SECTION I - CLASS DEFINITION
Class 83 is the residual locus of patents directed to methods
and machines for penetrating material, without substantial reshaping
flow of such material, by means of (1) a solid tool, or fluid current,
either of which applies mechanical deforming force to the material
by direct physical contact therewith, the fluid current forcing
the material against a solid tool whose edge defines the line of
cut; (2) a heated solid tool which directly engages the material
(to effect penetration thereof by melting, or by transmission of
mechanical energy, or both); or (3) opposed, controlled fluid currents.
(A) Specifically (as well as implicitly) excluded, is a patent
to apparatus or process for cutting by the transmission of heat
to the work material from a hot gas, such as flame cutting (for
the location of which, see Lines With Other Classes, subsection
A, Relationship to Other Classes Including, per se, Cutting, Severing,
or Incising, paragraph 8, Classes related to flame or other heat-cutting).
(B) While a disclosure of the production of a reshaping flow,
in the operation of its apparatus or accomplishment of its method,
will preclude original placement of a patent in this class, a disclosure
of a flow of the material which is inherent in, or purely incidental
to, the act of cutting will not operate as such a bar. The following types
of factual situations illustrate the rule:
(1) A disclosure that the work material flows, due to melting,
will not preclude placement herein of the patent so disclosing;
but the further teach-that the flow accomplishes a significant or
definable reshaping of the work beyond that inherent in the penetration
there-of will bar such placement. Exemplary of such reshaping is
the formation of a rim or bead around a hole coincident with the
penetration which forms the hole.
(2) A patent to a cutting machine or process employing a tool
which, as disclosed, creates a flow of the material while penetrating
the material only partially (that is, it fails to reach the surface
opposite the surface of entry) will be excluded from this class
only if there is a teaching from which it can be fairly inferred
that there is no severance of the surface fibres of the work, but
rather that the material is compacted, creased, forged or otherwise
plastic worked, thus indicating that the reshaping is not an incident
of a cutting operation. A disclosure that a "cutting" tool
penetrates only partially through tacky, flowable, or green, plastic
work material (such as soft synthetic "plastics",
food dough, etc.) will be considered to supply such a teaching,
unless (by the same disclosure) the work attains its flowable or
soft condition by the action of the cutting tool (e.g., a hot tool).
If such tool is disclosed as softening or plasticizing the work,
a patent directed to same would be proper for this class (83).
SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
SCOPE OF CLASS 83
Class 83 is an elemental or basic class. That is, its subject
matter is restricted (so far as possible) to means for, or steps
of, accomplishing the following functions: cutting something (the "work");
or cutting, and handling the work to be cut; or cutting, and handling
the product of the cutting operation. As a result, the great preponderance
of patents directed to cutting combined with some other work treatment
will be found in the respective class of the other treatment or
in some more general class of combined operations, such as Class
156 or Class 29 (particularly subclasses 33+ and 566+).
The few exceptions to this general statement are set forth explicitly
in section II, Lines With Other Classes, subsection B, Relationship
to Other Treating Classes (which appears later in this class definition).
The class does not act as the sole repository for patents directed
to cutting machines or even to cutting machines of the functional
types signalized in the subclasses of the class. Based upon past
development of the system of patent classification, such patents
are to be found in many classes, their disposition depending mainly
upon the nature of the material disclosed as constituting work for
the cutting operation. A listing of such classes is included in
Lines With Other Classes, subsection A, Relationship to Other Classes
Including, per se, Cutting, Severing, or Incising (which appears
later in this class definition). With respect to such classes,
Class 83 is residual.
As an incident of such residual nature, this class will not receive
for original placement a patent disclosing alternative embodiments
(claimed generically, or with a specific claim to each), one of
a type proper for this class and one of a type related to another
cutting class or subclass. Nor will it so receive a patent disclosing
two purposes for a claimed cutting machine, one general or related
to the art of this class (as shearing metal) and another specific
to another cutting class or subclass (as, for instance, cutting
plastic block or earthenware; or nail making). In both such cases,
the original patent will be placed in the other cutting class or
subclass.
A. RELATIONSHIP TO OTHER CLASSES INCLUDING, PER SE, CUTTING,
SEVERING, OR INCISING
The following enumeration and discussion of such classes,
although including the loci of patents relating to many and varied
types of cutting, does not purport to be exhaustive:
1. The class of cutting implements, Class 30.
Other than as governed by the exception set forth immediately
following description 4 below, a patent is deemed to be directed
to a cutting implement, and thus to be placeable originally in Class
30, if its claimed subject matter fits any one of following descriptions:
a. A cutting device which as an entirety is disclosed to be
supported or held against the force of gravity by the operator during
cutting.
b. A cutting device which as an entirety is disclosed as deriving
from the work a substantial amount of its support against gravity
(i.e., work-supported) during cutting, including a cutting device
which is disclosed as being guided and supported during cutting
by a member which is itself supported on the work (i) a cutting device
which is disclosed as having a loose, work supported tool and powered
means for driving the tool into the work, will be placed in Class
83; (ii) a cutting device which includes means to affix, hold, or
positively locate a portion of the device relative to the work,
for support of the device against gravity, and means to guide movement
of the cutter relative to the work-affixed or work-located portion,
will be placed in Class 83; (iii) a cutting device which includes
(1) means to position or positively locate a portion of the device
relative to the work in such a manner that said portion remains
in said relative position during cutting and (2) means to guide
the cutter in predetermined path with respect to said portion, will
be placed in Class 83.
c. A cutting device which is disclosed as being capable of
movement in a random path instantaneously under the control of the
operator during cutting, including a cutter suspended or supported
near the work; e.g., a cutter mounted at one end of a flexible shaft
whose other end is anchored to a table, or a cutter suspended from
a trolley, or a cutter mounted on a steerable vehicle.
d. A cutting device of the type referred to in the preceding
paragraph in combination with a work support or work holder wherein
neither the cutting tool itself nor the tool support is modified
or constructed to either constrain the motion of the cutter or to
guide it in a predetermined path with respect to the work support
or work holder.
However, a patent drawn to a device including a cutting tool
and means to support a reserve stock of the work in which the work
supply is in the form of a web or strand wrapped upon itself and
the supply is supported for rotation upon an axis will be placed
originally in this class (83) even though it fits one or more of
the above listed descriptions.
A patent for the combination of a cutting device meeting any
of the criteria set forth above and a work holder provided for in
Class 269 will be placed originally in Class 30, although a patent
for the work holder, per se, will be placed in Class 269.
A patent which only claims a cutting tool nominally, that
is, in which the claimed structure does not sufficiently define
a cutting tool substantially in its ultimate use form, or elements,
adjuncts, or materials structurally limited to such use, is regarded
as proper subject matter for original placement in Class 428, Stock
Material or Miscellaneous Articles.
2. The class of severing by tearing or breaking.
Class 225 includes patents for process or apparatus for severing
determinate portions of work material by causing failure of the
work under tension at the point or line of separation, effected
by moving one part of the work relative to another part. In such
devices or processes, the tension is applied by stretching, bending,
twisting, manually or mechanically grasping the work on one side of
a fixed edge and forcing it against the edge, or moving a breaking
or tearing tool and supported work material relative to each other.
Also included in the reference class are tearing or breaking devices
combined with any other type of severing means.
For a detailed statement of the distinction between Classes
83 and 225, see the (1) Note and (2) Note under section I, Class
Definition, subsection B, Breaking or Tearing, of Class 225.
3. The class of comminuting.
Class 241, Solid Material Comminution or Disintegration, includes
original patents for process or apparatus directed to the cutting
or severing of solid material into a number of smaller solid masses,
which smaller masses do not have imparted to them any desired or
significant shape. As between Classes 83 and 241, the provision
of means for (or steps of) retaining an original dimension of the
work in the cut up product will exclude a patent for the apparatus
(or process) from Class 241.
4. The class of selective cutting.
The art of selective cutting is collected in Class 234, Selective
Cutting (e.g., Punching). The distinction between a selective cutting
device or a method of selective cutting (either of which is proper
for Class 234) and a cutting means or method of this class (83)
is set forth in the following statement:
Class 234 is superior to Class 83, and takes or contains original
patents directed to cutting devices as defined in Class 83 which
are further distinguished by the claimed inclusion of a plurality
of cutting tool pairs and an actuating power train for each pair
(one power train may be common to all), so that power may be delivered
to any or all pairs for any cutting cycle, and wherein each and all
of the tool pairs assembled in the machine are constantly available
to be chosen for cutting or noncutting (in any desired number, from
one to the total number available) by (a) a pattern (b) combinational
coding means [defined in section III, Glossary, of the
class definition of Class 234, Selective Cutting (e.g., Punching)], or
(c) means not a part of the tool actuating power train and which
does not partake of all the movements of either tool or the pair;
which pattern or means conditions which pair so chosen to (a) enable,
or (b) prevent, a cutting operation thereby when its driving power
train is actuated.
The distinction expressed above is intended to exclude from
Class 234 patents for devices wherein, for example, (a) there is
no distinct conditioning means [see U.S. Patent No. 682,197
(subclass 225 of Class 83) to Hollerith: each punch is selected
and actuated by its individual key-connected linkage];
or (b) less than the whole number of tools is constantly available [see
U.S. Patent No. 878,775 (subclass 552 of Class 83) to Colbert:
a turret of tools]; or (c) the tool conditioning means
move bodily with their associated tools [see U.S. Patent
No. 746,625 (subclass 559 of Class 83) to Allen: manipulable locking
pins are fixed to the tools]; and is intended to include,
for example, devices wherein a tool-actuating power train common
to all tools is tripped, manually or automatically, after operation
of selected conditioning means [see U.S. Patent No. 1,110,261
(234/111) to Hollerith: initial depression of a key conditions
one punch for actuation, and further depression of the key trips
a common punch hammer or actuator], and devices wherein
a plurality of combinations of less than the total number of tools
are actuated or conditioned for actuation, by coding means (see
U.S. Patent No. 422,728 to Clark: a turret of coded interposers
is positionable to select groups of tools from an array thereof).
5. The class of mechanical manufacturing (metal working).
The class of reference (29, Metal Working) includes patents
for machines for bias cutting of tubular stock (subclasses 2.1+);
shredding metal; e.g., metal wool making (subclasses 4.51+);

76.1). Patents for files and rasps are found in subclasses 78+.
6. The class of presses.
The class of reference, (100, Presses) includes patents for
reciprocating press structures, which (as both claimed and disclosed)
may perform, alternatively, a cutting operation or some other forming
operation (such as forging, drawing, bending), as well as patents
containing such equivocal disclosures of forming devices that the
type of forming operation such devices are intended to perform cannot
be ascertained accurately.
7. The class of abrading.
With few exceptions (such as those found in Class 132, Toilet),
patents claiming a cutting means, or a step involving the use of
a cutting means, which (as disclosed) is composed of crystalline
material-removing particles, are placed originally in Class 451,
Abrading.
8. Classes related to flame or other heat-cutting.
In addition to the classes enumerated below, it will be noted
that subclasses 18.1+ of Class 33, Geometrical Instruments,
contained original patents for flame-cutting scribers, and that
Class 65, Glass Manufacturing, subclass 113, provides for glass
preform treating including flame severing, and subclasses 269+ provides
for glassworking means including flame severing means.

on the heat generated by the flame to perform its function; e.g.,
vaporize fuel.
d. The class of electric heating.
Class 219, Electric Heating, includes original patents directed
to methods or apparatus effective to sever, part, or burn or melt
away, a portion of a workpiece without using a solid tool which
engages and penetrates the work. Examples will be found in subclasses
68+.
e. The class of fluid sprinkling, spraying, and diffusing.
Class 239, Fluid Sprinkling, Spraying, and Diffusing, includes
original patents for fluid distributing nozzles or tips, per se,
even though disclosed as burners.

cast type are included in subclass 59 of Class 199, Type Casting.
f. A patent directed to cutting metal (or other hard substance
whose cutting is not the subject of a subclass is some other class)
will be placed originally in one of the following classes, if not
earlier placed on the basis of product (e.g., nails) according to
the criteria expressed:
i. Class 408, Cutting by Use of Rotating Axially Moving Tool,
will take original patents to machines for making a hole, reducing
the outside of a round workpiece, trepanning, screw threading either
the outside or the inside of a tubular workpiece, as well as any
other cutting operation by use of a tool turning about an axis and
moving along that axis toward a workpiece; provided, there is no
additional motion of the operating tool. Class 408 is intended
to ultimately include all cutting in the manner provided in the
definition of that class; however, not all classes have now been
screened for art proper for Class 408. Included among the classes
likely to include patents proper for Class 408 that have not been
screened are Classes 82, 142, and 451.
ii. Class 82, Turning. Original patents for devices or processes
for severing or cutting off work, wherein the cutting movements
of tool and work relative to each other include (1) rotation of
either or both about an axis passing through the work (except as
provided for in Class 408) and (2) relative translation substantially
normal to said axis, are in Class 82 as meeting the general concepts
of "turning".
iii. Class 409, Gear Cutting, Milling, or Planing, includes
original patents for a process and apparatus for shaping material,
usually metal, by means of (1) a toothed rotary cutter to produce
an article of desired configuration or (2) a nonrotary tool for
making a series of comparatively light cuts or a series of such
tools, between which tool(s) and the workpiece there is a relative
reciprocatory movement in substantially a straight line. Generally,
Class 409 is broad enough to take any patent for shaping by means
of a toothed rotary cutter not provided for in Class 77 or Class
82. Included in Class 409, subclasses 288+, is a patent
for a single edge cutter device which shapes work (e.g., grooving,
shaving, slotting, or flash trimming) by means of relative movement
between tool and work in one or more passes. See (1) Note under
Class 409, subclass 288.

or Class 30, Cutlery (including pencil sharpening implements in
subclasses 451+); except for patents directed to veneer-web
or -sheet clippers (including those intended to cut a layer to be
laminated) which are placed in this class (83).
11. Classes related (in whole or in part) to cutting the earth
or the fruits thereof in situ, or well tubing imbedded in the earth.
A patent directed to a machine or process for accomplishing
any one of the above enumerated purposes will be placed in the appropriate
earth exploring or exploiting, or agricultural, class. A list (not

16. Textile classes.
a. The class of cloth finishing.
Subclasses 7+ of Class 26, Textiles: Cloth Finishing, constitutes
the locus of original patents limited to apparatus or process for
severing threads or fibers projecting from textile fabrics. Such
patents may relate, for instance, to shearing or to the cutting
of float threads, pile loops, or weft ends.
b. The class of fiber preparation.
Patents for "tow-to-top" staplizing machines
or methods are placed originally in Class 19, Textiles: Fiber Preparation.
The type of severance therein involved is that in which a bundle
of filaments of indefinite length (termed "tow")
is subjected to a treatment which reduces the individual filaments
to staple length fibers without disrupting the continuity or integrity
of the bundle (which, when emerging from the machine or processes,
is known as "top"). In Class 83, on the other
hand, are found patents for machines or processes for the reduction
of isolated individual filaments to staple length fibers (for instance,
Beria-type cutters) or for the disruptive reduction of filament
bundles to such fibers, in both cases without further textile treatment.
c. The class of weaving.
Original copies of patents for cutting devices mounted on
loom parts (e.g., temple mounted cutters) are found in subclasses
302+ of Class 139.

machines will be found, as original copies, in subclasses 45 and
285-301 of Class 112.
e. The class of apparel apparatus.
Means for trimming the bottoms of dresses or skirts, for trimming
hat brims, or for cutting (e.g., clipping) the nap of hats comprise
subject matter of patents in subclasses 1.1, 16, and 19 of Class
223.
f. The general class of textiles.

Subclasses 127+ and 135+ of Class 400, Typewriting Machines,
includes original copies of patents drawn to keyboard operated means
for cutting intelligence-bearing indicia, as, for instance, stencil
cutting, and to processes utilizing such means.
b. The class of printing.
Generally speaking, the recording of intelligence by cutting
is proper subject matter for Class 101, Printing. More particularly,
individual cases of cutting machines or method may be tested for
aptness to Class 101 by reference to the following statements:
i. A patent for a machine or process for cutting on or adjacent
the printed or written matter on a document to prevent unauthorized
or fraudulent alteration of such matter due to the proximity of
the cut surfaces to the printed or written matter (e.g., check protecting)
will be placed originally in Class 101, subclasses 3.1+.
ii. A patent for a machine or process for cutting work in the
form of a character, a design, or a pattern which will impart information
to an observer is proper for Class 101, subclasses 3.1+,
if a cut is disclosed as extending only part way through the thickness
of the work (e.g., embossing). If all of the cuts forming such character, design,
or pattern are disclosed as extending all the way through the thickness
of the work, the patent will be found in Class 83.
iii. If in addition to a cutting machine or process of this class
(83) there is claimed a means or step peculiar to Class 101, (e.g.,
the application of ink to the cutting tool to additionally outline
or mark an aperture made by the punch), such addition has been considered
sufficient to place a patent directed to such combination in Class 101,
subclasses 3.1+. This is in accordance with the general
rule that a patent for a combination of cutting with another treatment
of the work will be placed in the class of the other treatment.
(See subsection B, Relationship to Other Treating Classes, below).
iv. An original patent claiming both the process and apparatus
for the manufacture of stencils by cutting, or only such process,
will be found in Class 101, subclass 128.4.
c. The class of recorders.
A process or apparatus which would be otherwise proper for
Class 346, Recorders, will not be removed from the scope of that
class merely by virtue of the fact that the recordation, as claimed,
is accomplished by an incising or penetrating means or method step.
d. The class of registers.
Original patents directed to means for cutting or punching
a record medium, in response to the results of the operation of
a calculating machine or register, will be found in Class 235, Registers,
particularly subclasses 58+ and 60.27+ (especially
subclass 60.29).
e. The class of railway signaling.
Patents for apparatus which cuts or punches a record medium,
in response to the operation of a block-signal system or of a cab
signal or train control device, are placed originally in subclasses
107 and 185 (respectively) of Class 246, Railway Switches and Signals.
f. The class of telegraphy.
A patent for a cutting device which is actuated by means responsive
to a telegraphically transmitted signal will be placed originally
in Class 178, Telegraphy, those in subclass 92 being typical.
g. The class of binder devices releasably engaging aperture
or notch of sheet.
A sheet binder device of that class (402) (i) in combination
with a discrete sheet aperture forming device, which device perforates
a sheet prior to placing the same on the retainer, (ii) including
means to force a sheet upon the sheet retainer and (iii) including
a sheet retainer which penetrates and inserts a pliant strand through
a sheet will be found in subclasses 1, 7, and 25, respectively,
of Class 402.
18. Receptacle classes.
a. The class of deposit and collection receptacles.
Patents claiming a ticket receiving and collection receptacle,
with means to punch or cut tickets introduced into the receptacle,
will be found placed originally in Class 232, Deposit and Collection
Receptacles.

patents for general-utility receptacles with attached openers which
function to open the receptacle by cutting part thereof.
19. Certain other classes distinguished by the nature or identity
of work or product.
a. The class of tobacco.
Patents for machines which are disclosed as being specially
adapted to the cutting of tobacco or cigars will be found, as original
copies, in subclasses 248+ and 281 of Class 131. (Patents
for tobacco cutting machines of more general utility are placed
originally in appropriate subclasses of Classes 30 and 83).
b. The class of button making.
Patented machines or processes for cutting button blanks are
disclosed in subclasses 15 and 16 of Class 79.
c. The class of brush, broom, and mop making.
The class of reference (300) includes a subclass (17) restricted
to the, per se, trimming of articles of the class. Most of the
devices represented by patents therein operate to accomplish such
trimming by cutting.
d. The class of wheelwright machines.
Patents directed to machines and processes for lacerating
or buffing the exterior surface of vehicle tires are collected in
subclass 13 of Class 157, Wheelwright Machines, except those claiming
an abrading means or step, which latter are to be found in Class
451, Abrading.
e. The class of ships.
Patents for ships carrying means to cut or break ice are placed
originally in subclasses 40-42 of Class 114.
f. The class of chemical manufacture and adhesive bonding
of articles.
Class, 156, Adhesive Bonding and Miscellaneous Chemical Manufacture,
provides in subclasses 625+ for severing a workpiece by
the action of a reactive or solvent fluid. It also provides for
the combination of laminating and cutting in subclasses 250+ and
510+.
20. The class of geometrical instruments.
Subclasses 18.1+ of Class 33, Geometrical Instruments, include
original patents for means for scoring or indenting a reference
point, respectively.
B. RELATIONSHIP TO OTHER TREATING CLASSES
1. This class is an elementary class and generally does not
include patents claiming the combination of a cutting method or
means with a process or apparatus for other treatment(s). Certain
specific exceptions to this general rule exist, as follows:
a. Heating or cooling work and cutting same.
Subject matter of subclasses 15+ and 170.
b. Cleaning work and cutting same;
subject matter of subclass 168.
2. Means for, or steps of, performing certain other operations
whose character as treating or nontreating operations, it is recognized,
will vary with individual judgement also are included in patents
of this class in claimed combination with cutting instrumentalities
or steps, as follows:
a. Weighing the cut product in subclass 77.
b. Separating or assorting product in subclasses 102+
c. Applying a transient, nonpropellant fluid (e.g., lubricant
or coolant) to work in subclasses 22 and 169.
d. Temporarily deforming work; in subclasses 17+,
175, and 176.
e. Unwinding material from, or supporting material on, a spool,
beam, bobbin, or the like, for presentation to a cutting device
for operation thereon; note particularly subclasses 649+.
(The combination of a cutting machine and significantly claimed
means for winding the product thereof is subject matter for Class
242, Winding, Tensioning, or Guiding, as is the Combination of a
winding machine and a means to cut the tail, extending from a package
wound by such machine, from the source of material to be wound.
See Class 242, subclasses 487.1+, 521, and 522+.
3. As to methods, the claimed recitation of a step of performing
a treatment other than cutting will exclude a patent from original
placement in this class, regardless of whether such treating step
is claimed in detail.
4. In interpreting a claimed combination of cutting and noncutting
treating means, a purely nominal recitation of the other (noncutting)
treating means will not exclude an original patent from this class
if all of the following conditions are met:
a. No means or instrumentality is claimed as being synchronized
with the other treating means.
b. A single material handling means presents work to both
such treating means; or, the means which presents material (as work)
to a second treating means in line is the means which removes it
(as product) from a first treating means in line.
c. No support or guide means is claimed as orienting or redirecting
the material (work or product) between treating means.
C. RELATIONSHIP TO MATERIAL HANDLING CLASSES
1. Product handling means.
a. This class (83) receives original patents claiming significantly
both a cutting tool of the class and means to separate or assort
portions of the product resulting from the cutting operation. An
original patent claiming such separating or assorting means in structural
terms, and the cutting tool in nominal terms only, will be placed
in Class 209, Classifying, Separating, and Assorting Solids.
b. Original patents drawn to the combination of cutting means
of this class and product weighing means which does not govern the
operation of the cutting means will be placed in this class (83)
without regard to the degree of specificity with which the cutting
means is claimed therein. If the weighing means is claimed as controlling a
cutting device, which cutting device terminates feed or flow of
material to the weighing means, a patent thereto is placed originally
in Class 177, Weighing Scales.
c. As to other product handling devices (i.e., instrumentalities
which effect or affect motion of the product of a cutting machine),
the claimed combination of such device with a cutting machine constitutes
subject matter for this class (83), regardless of the degree of
specificity with which the cutting means is claimed.
2. Work handling means.
a. As between this class (83) and Classes 193, Conveyors,
Chutes, Skids, Guides, and Ways; 198, Conveyors: Power-Driven;
212, Traversing Hoists; 414, Material or Article Handling; 226,
Advancing Material of Indeterminate Length; 406, Conveyors: Fluid
Current; and 271, Sheet Feeding or Delivering; the claimed recitation in
purely nominal terms, of a cutting instrumentality with respect
to which a work handling means may move or feed work will not of
itself exclude placement of an original patent for such work handling
means in the respective material handling class listed above. However,
when such instrumentality is set forth with structural specificity,
the claimed congregation of elements is properly placed with the
work modifying instrumentality (class 83). For example: A claim
reciting a structurally defined work handling means (not claimed
as synchronized with a work modifying means), and a "work
station" (or "tool station", or "work
modifying means", or "tool", or "cutter",
or "punch", or "knife", etc.)
in so many words, is properly placed on the basis of the work handling
means. A claim reciting a work handling means and, for instance,
a work station including a "reciprocating tool element",
or a "tapered tool", or a "round cutter",
or a "rotary punch", is properly placed in the
class of the specific tool set forth. The true test for proper
placement in this class (83) is whether or not the combination of
a tool and work-feed means is a significant tool-to-work-relationship.
For further notes on this relationship see (2) Note, under subclass
703 of this class (83) referring to Class 414.
c. Further, this class (83) receives original patents claiming
a cutting tool (of the type provided for in the class) synchronized
with or in power-transmitting driving relation with, a work handling
means, regardless of whether such tool is claimed significantly
or merely nominally.
3. Tool handling means.
Class 483 provides for a Class 83 cutting process or apparatus
combined with tool changing.
D. RELATIONSHIP TO CLASS OF TOOL DRIVING OR IMPACTING
Class 173, Tool Driving or Impacting, provides for subject
matter directed to driving or impacting a tool, when such subject
matter includes combined features peculiar to tool driving, but
which does not include features limiting the subject matter to a
specific tool art such as specific shape of the work contacting
portion of a tool, related tools, or an opposed work support. Class
83 has not been cleared as to subject matter in conflict with this line.
E. RELATIONSHIP TO THE CLASS OF WORK HOLDERS
This relationship is set forth in section II, Lines With Other
Classes, of the class definition for Class 269.
F. STRUCTURE OF THE CLASS
1. A perusal of the first line or skeleton schedule of the class
will reveal that the class is composed of a relatively small number
of major subclass groups. Generally, in order of superiority, these
major subclass groups provide search fields for:
a. a method including a step of cutting (subclasses 13-56).
b. noncyclic means to halt or prevent motion of a part or all
of a cutting machine (subclasses 58-68).
c. means to monitor and control operation of a cutting machine
(subclasses 72-76).
d. means to handle the product of a cutting operation (subclasses
78-166).
e. means to cut hollow work from the inside (subclasses 178-195).
f. means to cut work while cyclically halted (subclasses 202-283).
g. a flying cutter (subclasses 284-349).
h. a cutter (of a type other than those previously enumerated)
synchronized with work moving means (subclasses 350-357).
i. a cutting machine with an appurtenance such as a clamp,
work stop or gauge, work guide; firstly, synchronized with the tool
cycle (subclasses 373-398), and secondly, not so synchronized (subclasses
438-468).
j. means to control the operation of a part (at least) of
the machine in response to means to sense the work, product, or
another part of the machine (subclasses 358-372, 399, 400).
k. a cutting machine having work moving means not claimed
as synchronized with the tool cycle; providing for tool-station-type
work moving means (subclasses 401 through 437.7).
l. a rotatable disc type cutting machine (subclasses 469-508).
m. means to produce or facilitate the cutting motion of a tool
or tools (subclasses 513-519; 523-647).
n. a cutting tool, per se, or combined with its support (subclasses
651-699.61).
o. a method of, or means for, cutting other than all the way
through the work thickness-wise, providing for scoring, skiving,
and related operations (subclasses 6-12).
2. In addition, a limited number of groupings have been established
on secondary bases of classification, to facilitate state-of-the-art
searches. These subclasses, which contain no original patents are
numbered from 901.
The following index is provided for convenience in locating
certain elements or types of cutting machines according to keywords
generally of art terminology. This index is not intended to be exhaustive.

SECTION IV - GLOSSARY
ANVIL
A tool comprising a smooth-faced, imperforate member, the
smooth face having the purpose of contacting the work and providing
a reaction surface against which a relatively movable tool may abut
in its work penetrating movement.
DETECTOR
A mechanism for sensing a physical property or characteristic
of, or the presence or absence or passage of, the work or the product
or a movable element of a machine; which mechanism effects a signal
or impulse as a result of such sensing. The signal or impulse is
sent through a transmitter, (see definition of "transmitter" below)
and effects or initiates the functioning of a machine part or assembly
controlled by the detector.
FLYING
Moving with the work material. The term "flying" means
that the part so described has, at the time of cutting, a motion
component in the direction of the work as it moves to and through
the cutting station.
GUIDE
Passive means to direct the movement of something (e.g.,
work, product, machine part) in a desired path. (Note: although
a guide may be movable for the purpose of adjustment, yet it accomplishes
its directing function by presenting an obstacle to movement in
an undesired direction, rather than by causing the directed thing
or part to move with it).
NOTCHING
The cutting of a discrete product from a workpiece through
the thickness of the workpiece with the line of cut starting at
an edge of the workpiece and returning to the same edge. The edge
of the workpiece may be either an exterior edge or an interior edge.
A cut which extends solely along a single straight line is not
considered to be a notching cut.
PRODUCT
Material which has been treated by the cutting tool;
the result of a cutting operation. (Note: material which is "product" for
one cutting operation may be "work" for an ensuing
operation).
PUNCHING
The cutting of a discrete product out of the confines
of a workpiece through the thickness of the workpiece so that the
cut does not intersect any edge (exterior or interior) of the workpiece.
SHEARING
Cutting effected by the relative motion of two cutting tools
having edges which are initially on opposite sides of the work with
the cutting taking place by one tool moving towards the other tool
and the edge on the moving tool moving past and in close and overlapping
relationship to the edge of the other tool.
TOOL
The instrumentality that contacts the work for effecting directly
the operation of the class either by itself or by cooperation with
another tool.
TOOL CYCLE
The elapsed time between, and all of the motion traced by
the tool between, the time the tool leaves any particular datum
point in its approach to (or recession from) the work until it again
leaves that point in its next succeeding approach to (or recession
from) the work, the location of such datum point for a series of
recurring cycles being determined without giving significance to
mere positioning movements of the tool with respect to the work
(Note: positioning movements of the tool are considered to be part
of the cycle of motions constituting the tool cycle, and the time
they occupy is part of the span of the cycle. They are disregarded
only for the purpose of establishing the datum point of one cycle
with respect to that of a preceding or succeeding cycle).
TOOL PAIR
A plurality of tools, each having a work contacting portion,
said portions being initially separated from each other and cooperating
to effect cutting of the work when they have relative movement toward
each other.
TOOL STROKE
The motion of the tool toward and into the work to effect
a cut, and the motion of retraction of the tool from the product
to its base position.
TOOL SUPPORT
An element connected to the tool for supporting it against
gravity and that partakes of all of the movement of the tool and
has no relative movement with respect to the tool except for purposes
of adjustment.
TRANSMITTER
A system for sending the signal or impulse which has been
effected by a detector (see definition of "detector" above)
to a means for establishing (in response to receipt of such signal
or impulse) a driving connection between a source of power and a
machine part or assembly; or sending such signal or impulse to a
mart or assembly directly (as by a linkage).
WORK
Article, material, or stuff to be treated (cut). (Compare "product").
WORK-FEED MEANS
An instrumentality for advancing work to the treating (cutting)
zone.
WORK THICKNESS
In general, the least dimension along a substantially
planar outer surface of work. As to hollow workpieces, the thickness
dimension at an annular section is taken as the wall thickness;
at a solid section, it is the thickness of the entire workpiece
as though it were not hollow. The thickness dimension of a strand
is defined as follows: (a) as to those of circular, triangular
or elliptical cross-section, by any line passing through the strand
from surface point to surface point, (b) as to those of other polygonal
cross-section, by any line passing through the strand from one outer
surface to a nonintersecting outer surface. As to spheres a line
extending through the sphere from one point on the surface to another
is deemed to define the thickness dimension. As to all other shapes
of work pieces, thickness is not considered significant for the
purpose of this classification.
Throughout the definitions of subclasses herein below, the
appearance of an asterisk (*) will indicate a word or term
which has been defined in this section. However, the words "product", "tool",
and "work", defined in this section, occur so
frequently in the subclass definitions, that the use of the asterisk
in reference thereto has been omitted.
SUBCLASSES
![[List of Patents for class 83 subclass 13]](../ps.gif) 13 | PROCESSES: |
| | This subclass is indented under the class definition. Method which includes a step of cutting.
| | (1)
Note. A step of cutting, as herein applied, consists in moving
a tool and work into contact with and relative to each other such
that the tool moves entirely through the thickness of the work.
Once the cut through the wall thickness has been achieved, then,
an interruption of said relative movement, or of cutting contact
extending throughout said wall thickness, shall be construed as
a termination of said "step". |
| | (2)
Note. A special exception to the limitations expressed in
these definitions (i.e., the limitations which require a moving tool
and/or an edge backup member) exists in the case of wherein
sound waves (e.g., supersonic sound) cause work to be cut through
its thickness. Such a step will be proper for this class and this
subclass as a process of cutting. |

cutting step, of performing an operation (other than a cutting operation)
which changes the shape or state of the work, which change of shape
or state facilitates the cutting.
| | (1)
Note. The operation may either facilitate the operation of
the tool upon the work or effect a necessary or desired change of
shape of the work with respect to the tool. |
| | (2)
Note. Included in this subclass (14) are processes which
recite a step of placing the work under tension or compression; however,
applying such force for the purpose of merely immobilizing the work,
as by clamping, has not been considered a treatment step to admit
the patent to this subclass. Such patents are classified below
on other steps of their method. |

| | |
| 34 | With reorientation of tool between cuts: |
| | This subclass is indented under subclass 13. Process which includes a step of shifting the tool intermediate
successive cutting steps to rearrange or readjust the tool with
respect to the work.
| | (1)
Note. The mere movement of the tool toward and from the work
in its normal cutting cycle has not been considered reorienting.
The reorientation is superimposed upon the tool stroke, resulting in
such additional movements as a change from the previously normal
path of the tool during the tool feeding cycle, and inversion of
the tool, or an indexing of the tool. |

| | This subclass is indented under subclass 13. Process which includes a step of shifting the work intermediate
successive cutting steps to rearrange or readjust the work with

| | (1)
Note. The mere advancement of the work into the cutting zone
has been considered feeding rather than reorienting. The reorientation
is superimposed upon the work-feeding motion, resulting in such
additional movements as: a change in the path of an established
direction of feed, an inversion of the work, or a turning end-for-end
of the work. |

is moving through a cutting zone, which step includes moving the
tool, at the time of cutting, in the direction the work is moving.
| | (1)
Note. A method of slitting the work longitudinally of the
direction of work movement by means of a rotatable disc tool has
been excluded. Patents thereto will be found in subclass 56 below; whereas
patents for slitting apparatus will be found in subclasses 426+. |

| | This subclass is indented under subclass 37. Process which includes a step of changing either the speed
of the tool during a portion of its cyclic travel, (i.e., toward,
from, or concurrent with, the moving work) or the speed of the work
as it traverses the cutting zone.
| | (1)
Note. Oscillating and reciprocating tools of necessity have
a period of nonuniform rate of travel due to the reversals of direction.
Since such tools inherently operate in this manner, patents for
methods of operating them have not been included in this subclass
and will be found in other subclasses indented under subclass 13.
However, all patents for methods of operating unidirectionally moving
rotary tools which start their cycle of movement from a position
of rest have been placed here because of the difficulty distinguishing
between rotary tools which stop and those which merely slow down. |

| 57 | WITH MANUALLY ACTUATED MEANS TO DISTURB CYCLIC OPERATION: |
| | This subclass is indented under the class definition. Device which comprises means, actuatable by force applied
by and at the will of an operative, to override the normal cyclic
functioning of a part(s) of the device, which part(s) returns to
normal functioning when the application of the intervening force
ceases.
| | (1)
Note. The disturbance referred to is temporary and exists
only during the application of force by an operative. (Example:
A machine, set to cut products of a given size, is controlled by
a pushbutton to cut small pieces for sampling purposes). |
| | (2)
Note. The disturbance herein contemplated does not embrace
stopping. For disclosures, of noncyclic stopping means, see subclasses
58+; and, for cyclic stopping means, see other appropriate
subclasses whose titles include the work "stopping" or
equivalent term (e.g., subclasses 202+). |
| | (3)
Note. Adjustment of a device establishes a new condition
which persists indefinitely, and is thus distinguishable from a "disturbance" which
permits the disturbed part to return to the previous condition upon
withdrawal of the intervening force. |

thereof. |

| 58 | WITH RANDOMLY ACTUATED STOPPING MEANS: |
| | This subclass is indented under the class definition. Device provided with means capable of bringing any or all
of the moving parts of the device to a halt, such means acting to
accomplish its halting effect in response to a signal or impulse
which cannot be predicted to occur during any particular one of
a number of recurring cycles of operation (either of the machine as
a whole, of the tool, or of any part of the machine which has a
cyclic law of operation).
| | (1)
Note. Such means may comprise, for example, a device effective
to disrupt the flow of power to a part or all of the machine, as
by effecting the disconnection of the parts of a clutch. |
| | (2)
Note. It is not a bar to original placement of a patent in
this subclass, that the claimed power train disrupting, braking or
other "stopping" means may be activated at a time
when the part to be halted is, purely adventitiously, at a standstill due
to its normal cyclic operation. |
| | (3)
Note. If, however, the normal and intended operation of power
disrupting, friction gripping, or other motion preventing means,
is to forestall the impending start of movement or activation of
a part of the device, then the motion preventing means is regarded
as an interlock and its claimed combination with an instrumentality
of a cutting machine is found in subclasses 399+, below. |
| | (4)
Note. If the normal and intended operation of power disrupting
means is to forestall or prevent future movement of a tool or tool
support by disrupting its power-transmitting connection to an uninterruptedly
moving tool-actuating mechanism, the claimed combination of the
power-disrupting means with the tool support and tool actuating
mechanism is found in subclasses 572+, indented under subclass
571 in this schedule. |

| 72 | WITH MEANS TO MONITOR AND CONTROL OPERATION (E.G., SELF-REGULATING
MEANS): |
| | This subclass is indented under the class definition. Apparatus, each of whose parts has a desired operating condition
according to a law of operation; such apparatus being provided with
a detector for sensing a deviation of a part(s) (or all of the apparatus)
from its or their desired operating condition; and including means
to modify - in response to a signal or impulse transmitted by said
detector - (a) the cyclical operation of such part(s) (or the entire apparatus)
to correct the deviated operating condition; and/or, (b)
the normal cyclical operation of another part(s) to compensate for
the deviated condition; whereby, in either event, the maintenance
of a normal cyclical desired operating condition of the apparatus
as a whole is achieved.
| | (1)
Note. The sensing or detecting may be direct; i.e., by determining
the operation of a component of the device (as, for example, in
U.S. Patent No. 2,175,828, wherein a driven feed roller is coupled
to a roller-speed detector); or may be indirect, i.e., by determining
the result of the operation of a component of the device (as, for
example, in U.S. Patent No. 1,961,538, wherein work is moved by feed
rollers, indicia on the work are scanned stroboscopically to detect
any variations in work speed imparted by the feed rollers, and such
speed variations are eliminated by correcting the feed roller speed). |
| | (2)
Note. Merely stopping or starting a cyclic component of the
device to effect the functioning thereof is not considered to be
modifying the operation of a component. However, a regulating means, which
accomplishes such modification of a cyclic operation, may itself
be started or stopped (to effect the cyclic operation), in response
to the detection of a deviation in the desired condition. (See,
for example, U.S. Patent No. 2,023,243, wherein the leading edge
of the work initiates the actuation of a regulating means, which
means compares the position and speed of the entering work relative
to the angular position and speed of a flying cutter and modifies
the angular position of the cutter to compensate for the entrance
timing of the work). |
| | (3)
Note. The imposition of a change upon a component by an operator
(e.g., physical relocation of a component) is not considered a deviation
within the meaning of the definition above. Thus, patents claiming
means for detecting operator-imposed changes, and means to vary
the operation of the device in response to detection of such changes,
will be found in other subclasses; e.g., subclasses 399+,
below. |
| | (4)
Note. Detection of an irregularity in the work, which irregularity
is not the result of a deviation in the desired operation, but is
a part of the work, is not considered a deviation detection within
the meaning of the definition above. Thus, devices claiming means
to detect such irregularities and means to vary the operation of
a cutting device in response to the detecting means, will be found
in other subclasses; e.g., subclasses 360+, below. |

| 76.1 | WITH CONTROL MEANS RESPONSIVE TO REPLACEABLE OR SELECTABLE INFORMATION
PROGRAM: |
| | This subclass is indented under the class definition. Device provided with memory means, i.e., a member in which
digital or analog data can be impressed for subsequent recall, and including
means to detect the data on the memory means and accordingly regulate
the operation of the device.
| | (1)
Note. The "memory" means of this subclass
may comprise permanently installed structure of the device or it
may comprise a removable tape or card. |
| | (2)
Note. A templet, per se, is not considered to be a replaceable
information supply; however, a device including a templet from which
information is retrieved and stored in the device is included in
this subclass. |

| | This subclass is indented under subclass 76.3. Device wherein the removable member on which replaceable
data is stored is generally elongated and wherein the device either engages
no end of the removable member or engages only the leading or trailing
end thereof.
| | (1)
Note. The replaceable member may be endless, or it may be
wound on a spool. | |
| | |
| 76.5 | Magnetic: |
| | This subclass is indented under subclass 76.4. Device wherein the magnetic characteristics of the removable
member are utilized in storing data thereon. |
| | |
| 76.7 | With condition sensor: |
| | This subclass is indented under subclass 76.6. Device including means to detect a characteristic other
than that of the "memory".
| | (1)
Note. The condition sensor of this subclass may respond to
work, product, a component of the device, or to the environment. | |
| | |
| 76.9 | With operator input means: |
| | This subclass is indented under subclass 76.6. Device also having means to alter the operation thereof
(without changing the program) at the control of the person operating
the device. |
| | |
| 77 | WITH MEANS TO WEIGH PRODUCT: |
| | This subclass is indented under the class definition. Device having means to determine the weight of a piece or
portion of the cut product.
SEE OR SEARCH CLASS:
| 177, | Weighing Scales, appropriate subclasses for the combination of a cutting
machine and a weighing scale which received material cut or to be cut
by the cutting machine, characterized by means for actuating, or
modifying the operation of, the cutting machine in response to determination of
the weight of material accumulated on the weighing scale; and
subclasses 60+ for weigh chamber responsive material control. |
| 198, | Conveyors: Power-Driven,
subclasses 504+ for a conveyor having load weighing means. |
|
| | |
| 78 | WITH PRODUCT HANDLING MEANS: |
| | This subclass is indented under the class definition. Apparatus including means to move, guide, or otherwise affect
the motion of, the product of a cutting operation - other than by the
mere provision of a receptacle or support into or onto which product
may descend at random (i.e., without necessarily assuming any regular
arrangement).
| | (1)
Note. A cutting machine including such receptacle or support
for receiving product in random arrangement constitutes subject
matter of subclass 167, below. |
| | (2)
Note. The handling given recognition by this and indented
subclasses is additional to that which inherently is accomplished by
the tool(s) in the cutting operation. A tool, qua tool, is therefore
not to be considered a product handling means. But a specific element
fixed to, or a portion integral with, a tool will be recognized
as a product handling means if there is a clear teaching, in the
disclosure of the device, that the element or portion performs a
product handling function. |
| | (3)
Note. Inasmuch as many work moving means of the cutting arts
also function to carry away the product of the cutting operation,
a patent whose only claimed means capable of product handling is
a device for moving, guiding, supporting, or stopping motion of,
work will not be placed originally in this subclass unless such
work handling device is claimed in terms of its specific product
handling function. (Of course, a patent claiming work handling means
in combination with additional means to give the work handling means
a product handling effect - such as means to tilt a work table to
effect product sliding - will be placed originally in this or an
indented subclass). |
| | (4)
Note. For the purpose of original placement in this classification,
a means to handle the product of one of a claimed series of tool
stations, while proceeding from such one station to a succeeding station,
will be considered a work handling means for the succeeding station rather
than a product handling means for the earlier station. (Disclosures
of such means may be placed as cross-reference copies in this or
indented subclasses, where deemed pertinent). |

relative to the conveying direction. |
| 242, | Winding, Tensioning, or Guiding,
subclasses 487.1+ and particularly subclasses 522+ and 911
for cutting a product which is subsequently wound classified along
this line: Patents which claim a device for cutting material and
for winding are placed in Class 242 whereas patents which claim
a device for cutting material supplied from a wound source, or in which
disclosed structure for winding a cut product is not significantly claimed
are placed in Class 83 or related Class 225 (Severing by Tearing
or Breaking). |

subclasses 278+ for a device for removing individual sheets to
some determined position (where no means to treat the sheet is claimed
specifically). |

for placing or displacing articles in a particular manner, as in stacks
or piles; also for a carrier or forwarding mechanism of general type
combined with special means for placing the load on the carrier
or removing it therefrom (where no means to treat the material is
claimed specifically). |
|
| | |
| 79 | Initiated by means responsive to product or work: |
| | This subclass is indented under subclass 78. Device including a detector* for sensing product
or work, a transmitter*, and means to effect or initiate
product handling or delivery as a direct or indirect result of the
receipt by said means of a detected and transmitted signal or impulse.
| | (1)
Note. As between Classes 83 and 209, patents claiming significant
assorting of the work for, or the product of, a disclosed cutting
device will be placed as an original copy in Class 209 unless the cutting
device also is claimed significantly, in which latter case the original copy
will be placed in this class (class 83). |
| | (2)
Note. Included in this subclass are patents disclosing the
sensing of product and the initiation of product handling responsive
thereto, whereas subclass 80 (indented hereunder) is the repository
for patents disclosing product handling responsive to work sensing. |

| | This subclass is indented under subclass 78. Device including a detector* for sensing the presence
of a moving tool, or of an element partaking of all tool motions,
at a predetermined point in the path of motion of said tool or element;
and including a transmitter* and means to effect or initiate
product handling or delivery as a direct or indirect result of the receipt
by said means of a detected and transmitted signal or impulse. |
| | |
| 83 | Including means to drape the product: |
| | This subclass is indented under subclass 78. Device which comprises, as part at least of the product
handling means, or is additionally provided with, means adapted
to receive and support the cut product with the ends of the product
depending downwardly on opposite sides of the support means. |
| | |
| 84 | Including means to form or hold pile of product pieces: |
| | This subclass is indented under subclass 78. Device which includes structure for placing or retaining
product pieces in some regular order relative to, and in contact
with, one another.
| | (1)
Note. Included in this group of subclasses are patents which
disclose that elongated product pieces are arranged in substantial
parallelism or that flat product pieces are arranged sequentially
in face-to-face contact. |
| | (2)
Note. As indicated by the subclass definition, a patent claiming
a receptacle or support which is disclosed as serving to receive
and retain the product pieces in an orderly arrangement will be
included in this group of subclasses. However, where there is no
teaching that the product pieces are placed or held in the receptacle
or on the support in some regular order the patent will be placed
in subclass 167, below. |

| | This subclass is indented under subclass 84. Device which has means to place together, or retain, a plurality
of similar nonplanar cut pieces in sequential interfitting order,
with at least a portion of one piece located within, and in contact
with, a mating hollow portion of the next adjacent piece. |
| | |
| 86 | In stacked or packed relation: |
| | This subclass is indented under subclass 84. Device which has means to place together, or to receive
and retain, a multiplicity of substantially planar-faced cut pieces
in sequential face-contacting relation, supported one on another
or edgewise on a common base.
| | (1)
Note. A stack or pack is formed by superposition or juxtaposition
of the pieces thicknesswise. Herein, and in the indented subclasses,
the term "stack" will be used to designate the
concepts generally included in both the terms "stack" and "pack". |
| | (2)
Note. Such stack need not be static but may be in motion,
such as one which is continually diminished at one end and replenished
at the other end. |
| | (3)
Note. A patent disclosing a device which includes a mere
product-conforming cavity in a hollow tool or in the tool and its
support, though it inherently holds the pieces in stack formation,
is not included in this group of subclasses (86+) but is
placed on the basis of other features. However, a stack holding means
which communicates with such tool or its support, or which is incorporated
as an added element within the tool or its support, its proper subject
matter for this group. |

| | This subclass is indented under subclass 86. Device including means to support product pieces, individually
or in stacks, in spaced relationship in substantially parallel planes
so that an edge of one such piece or stack is above the adjacent
edge of the next or adjacent piece or stack, and including stacking
means which moves along the support means for engaging the pieces
or stacks sequentially and moving them into superposed stacked relation
with each other. |
| | |

| | This subclass is indented under subclass 86. Device including means to arrange a series of cut pieces
on a product-moving support so that each piece of the series rests
partly in contact with the support and partly on an adjacent piece.
| | (1)
Note. Included in this subclass are patents disclosing apparatus
as above defined and further including means to place additional
cut pieces on the overlapped series. | |
| | |
| 89 | And means to separate product portions: |
| | This subclass is indented under subclass 86. Device including means to move one or more product pieces
from a stack, or to cause product pieces to proceed, or be directed
to, a stack, and other product pieces to proceed or be guided in
another direction (as, for instance, but not necessarily, to another
stack).

by moving the support on which the pieces are received to form the stack. |
| | |
| 92 | By timed relocation of holder along path of stack growth: |
| | This subclass is indented under subclass 91. Device in which means is provided to move the support progressively
broadside away from the source of product pieces as product pieces
are added to the stack.
| | (1)
Note. A typical device of this kind operates to keep the
product receiving end of the stack at all times in the same position with
respect to the source of pieces for the stack. | |
| | |
| 92.1 | Interrelated adjustment of holder movement and work-feeder: |
| | This subclass is indented under subclass 92. Device including means to vary the progressive broadside
movement of the product, which means is operatively linked to the
mechanism which adjusts the extent that a work-feeding device moves
between each cutting cycle.
| | (1)
Note. Included in this subclass are devices having means
to vary the thickness of product pieces being cut, which means effects
the adjustment of the movement of the product holder to compensate
for such variance in thickness. | |
| | |
| 93 | And means to resist stack movement: |
| | This subclass is indented under subclass 86. Device which includes means to oppose broadside movement
of the stick away from the source of product pieces as product pieces
are added to the stack.
| | (1)
Note. Devices including a receptacle telescoped over a stack
holder or guide in which the receptacle is moved by the growing
stack are typical of the art of this subclass. | |

pieces, formed by a tool having a cavity or aperture and a continuous
cutting edge bounding the open end of said cavity or aperture, after
the pieces have left the confines of the tool.
| | (1)
Note. The stack former may be claimed in some general term
such as "a chute"; but if, as disclosed, it actually
forms a stack, a patent therefor is placed here regardless of the
breadth commonly assigned to the name applied to such stack former. |
| | (2)
Note. For the distinction between this subclass and subclass
164, below, see (3) Note under the definition of subclass 86 above. | |
| | |
| 98 | By fluid current: |
| | This subclass is indented under subclass 78. Device which effects movement of product directly by means
of one or more jets or streams of liquid or gaseous material.
| | (1)
Note. The pressure of the fluid current may be superatmospheric
or subatmospheric. |
| | (2)
Note. Fluid pressure means (blast or vacuum) which function
merely to push or pull product into contact with a mechanical product-moving
or product-braking means do not constitute subject matter for this
subclass. Original patents claiming such fluid blast devices will
be placed in the subclass based on the nature either of the mechanical
product-moving means or the mechanical product-braking means. |

subclasses 97.1+ for means to advance material by fluid current. |
|
| | |
| 100 | By suction means: |
| | This subclass is indented under subclass 98. Device including means to produce a zone of subatmospheric
pressure so related spatially to the cutting zone or product path
that the product will move under the influence of atmospheric pressure
toward or through said zone of subatmospheric pressure.
| | (1)
Note. See (2) Note and the search subclass note under the
definition of subclass 98 above. | |
| | |
| 101 | By brush means: |
| | This subclass is indented under subclass 78. Device in which movement of the product is effected by frictional
engagement with bristles mounted on a backing having relative motion with
respect to the product. |
| | |
| 102 | Including means to divert one portion of product from another: |
| | This subclass is indented under subclass 78. Device including means for accomplishing one of the following
functions:
- causing contiguous (either touching or
adjacent) products which have been traveling along parallel paths
to now travel in diverging directions; or preventing their paths
from merging or overlapping;
- (b) causing, or permitting, product pieces which have been proceeding
seriatim along a common path to now follow respective discrete and
individual paths;
- (c) causing, or permitting, one or more product pieces to follow
a path away from the zone of separation while restraining one or
more pieces from proceeding away from the zone of separation (i.e.,
holding one piece back while another moves away);
- (d) dividing a moving group of products into smaller groups (or
units) traveling in the same direction of general path as that before
division; or
- (e) positively moving products from the zone of separation in
different directions.
| | (1)
Note. Such separation must be additional to that inherently
accomplished by the tool(s) in the act of cutting. |
| | (2)
Note. The removal (or facilitation of removal) of one product
portion from the as-cut position, while leaving the portion from
which it has been cut in the cutting zone to serve as work for a
succeeding cut by the same tool, is not considered to be separation. |
| | (3)
Note. The separation signalized by this subclass is distinct
from that brought about by means for moving a product from contacting
engagement with a tool (such as stripping or ejecting means). So,
the movement of product out of contact with a tool, even though
it may involve a motion away from another product portion, is not
considered a separation for the purpose of patent placement in this
and indented subclasses. |
| | (4)
Note. On the other hand, a product portion which has been
subjected to the action of a stripper- or ejector-type means (as
defined in subclass 111) is not considered (for the purpose of this
classification) to be closely adjacent to other product portions
from which the stripper or ejector has moved it apart, so that a further
movement of the portions in different directions will not be deemed
to be a separation. (A positive teaching that a stripper or ejector
places a product portion in actual contact with another portion,
however, will not be ignored). For patents claiming means to strip
or eject a product portion and thereafter convey it away, see subclass
112. |
| | (5)
Note. The combination with cutting, of separation accomplished
in response to a sensing of a physical characteristic of the pieces
to be separated (such as quality separation), is provided for in
subclass 79. |
| | (6)
Note. Merely allowing pieces to fall freely from a common
height or place of departure is not considered to permit them to
travel in substantially different directions. But diverting guides
which cause certain of the so dropped pieces to travel in one path
and others to follow a different path constitute separating means. |
| | (7)
Note. Since this subclass is specific to that of produce,
(i.e., cut work) handling, which requires the operation of motion-affecting
means additional to the work-feeding means, at least one of the
separated product portions must be directed to its destination by
means other than the work moving means. |
| | (8)
Note. Although separation inherent in a cutting operation
(e.g., the removal of certain product pieces through a hollow cutter)
is not sufficient to place here a patent disclosing such, a patent
directed to product separating means carried by a cutter is proper
for this and indented subclasses. |

gravitational field to act selectively on a plurality of product
portions; with the result that one portion or piece will move along a
path have a downward component, under the gravitational impetus,
while another portion or piece will move along some other path or
will be restrained from moving away from the zone of separation.

| 105 | Deflecting guide: |
| | This subclass is indented under subclass 102. Device provided with passive means for guiding a product
into a path diverging from that followed by another product.
| | (1)
Note. The deflecting guide of this subclass is effective
to direct a moving product portion into a desired path, not to hold
it from further movement. Stationary means (catchers) which prevent
a product portion from moving, while another portion continues in
motion, will be found in subclass 102 and in subclass 104 indented
thereunder. |
| | (2)
Note. The divergence effected by a guide of this type may
be either simultaneous with the passage of another product portion
through the zone of separation or may be temporarily spaced therefrom.
That is, the guide may operate on one or more product portions
traveling along parallel paths or moving seriatim along the same
path. |

Note. One of the product moving means may be a work moving
means, which may be claimed as such. |

moving and tool moving means is disrupted during or after each tool
cycle in such manner that the reestablishment of such relationship
and initiation or continuation of a succeeding cycle requires the
intervention of an external force or stimulus.
| | (1)
Note. Unicyclic operation is characterized by the requirement
of two inputs: one to supply actuating power and the other to intervene
and supply an unlocking force without which the machine could not
resume operation, as distinguished from the usual machine which operates
whenever power is supplied to it. Some type of "nonrepeat" mechanism is
required as part of the invention. |

| | (1)
Note. Impaling points or fingers which form their own recesses
or openings in the work are included here. |
| | (2)
Note. Push bars and the like which directly engage and push
the work are included here. The "abutment surface" engaged
by such pusher may be the rear edge of the work as well as any other salient
portion. |
| | (3)
Note. A feed member having a rough toothed, or corrugated
surface to engage work, if opposed by another moving surface so
as to clamp the work, would be classified in subclass 277, but if
opposed only by a stationary work-supporting surface or work guide,
or by the mere weight of the work itself, would generally be regarded
as imbedded in the work or abutting it within the scope of the definition
of subclass 278. |

control on the work (other than by merely supporting it against
gravity) before it reaches the means-to-feed it to the cutting zone.
| | (1)
Note. The first named means (guiding, positioning, or transport)
is not adequate of itself to present the work properly to the tool

| | (1)
Note. The transport means serves to advance work to the work-feed
means proper, but is not adequate in itself to move the work in
correct amount and proper timed relationship to the tool station,

| 284 | CUTTING MOTION OF TOOL HAS COMPONENT IN DIRECTION OF MOVING
WORK: |
| | This subclass is indented under the class definition. Device which includes means to move one or more tools into
cutting engagement with the work while the work is being moved to
and through a cutting zone to produce (a) spatially unconnected,
or (b) undulant (e.g., zigzag) cuts, and in which the tool"s
movement includes, as a necessary factor, motion in the direction
of such work movement.
| | (1)
Note. These devices are commonly known as "flying
cutters". |
| | (2)
Note. See section IV, Glossary, of the Class 83 Definition
for the definition of "flying". |
| | (3)
Note. The direction of movement of the work, to and through
the cutting zone; i.e., feed direction, is determined by the law
of operation of the disclosed machine, even though the work-feed means
is not claimed. Accordingly, this and the indented subclasses do
not require that means to feed the work be claimed. Thus, patents
for means to cut manually fed work may be included here if the other
requirements of the definition are met. |
| | (4)
Note. This and the indented subclasses are limited to devices
which engage the work so that cuts made by the same tool are spaced
from each other or produce a nonrectilinear slot or slit. Patents
for cutters which continuously engage the work, even though they
have a component of motion in the direction of work-feed which has
no affect on the resultant cut, such as band knives and rotary disc slitters,
will be found in other areas of the schedule. The test is whether
the "flying" motion has any affect on the desired
shape of cut. |
| | (5)
Note. Since indented subclasses 321+ is limited
to patents which disclose a tool having a cutting blade which moves
in an orbital path, this subclass, (284) has been chosen as the
residual repository for those patents which disclose an orbiting
anvil and a cooperating nonorbiting bladed tool, and which do not
disclose a feature set out in the schedule above subclass 321. |

| 286 | Tool moved in response to work-sensing means: |
| | This subclass is indented under subclass 285. Device provided with a detector* for work, a transmitter*,
and means to initiate or effect a tool action as a direct or indirect
result of the receipt by said means of a detected and transmitted
signal or impulse.
| | (1)
Note. For convenience in terminology, in this and indented
subclasses, the compound movement of a flying tool will be referred
to in terms of two components, one being the tool "flying
movement" (defined in the Glossary for the class), and
the other being the tool "feed movement)" (defined
as that component of motion directed only toward the work, i.e.,
toward the other tool of a tool pair). The distinction between the
named components is not an arbitrary one; in the schedule, and in
the placement of patents, components are significant as to those
patents which disclose separate actuating means to give the tool
its respective flying and feed movements. Thus a patent to a rotary
cutter of the "lawnmower" type (such as is found,
per se, in subclasses 331+ below) and including work-responsive
tool actuating means, will be found in a generic subclass such as
290 rather than in a subclass characterized by the type of feed
or flying movement such as subclasses 291 or 292, respectively. |
| | (2)
Note. Included in this subclass (286) are patents disclosing
tools revolving about a fixed axis (e.g., lawnmower type), which
tools are actuated by a mechanically operating detector and transmitter.
For similar structure wherein the detector is a photocell, see
subclass 289; and wherein it is otherwise part of an electrical
circuit, see subclasses 290+, indented hereunder. |

and control means responsive thereto, see subclasses 399+ under
the heading "Search This Class, Subclass". |
SEE OR SEARCH THIS CLASS, SUBCLASS:

tool"s motion is derived entirely from the engagement of
the tool with the moving work. |

| | |
| 287 | With means to vary "length" of product: |
| | This subclass is indented under subclass 286. Device provided with means to alter the dimension of the
product in the direction of work movement.
| | (1)
Note. For the purpose of this subclass, the length of a product
is that dimension defined above regardless of the magnitude of that
dimension relative to other dimensions; thus, as to this subclass,
the length of a product may be smaller than the width thereof if
short pieces are cut from relatively wide work. |
| | (2)
Note. Examples of the means defined above are means to effect
(a) variation of the position of the work sensor relative to the
cutter and (b) variation of the time elapsed between the sensing
of work and the initiation of the tool action in response to said
sensing. |

| | This subclass is indented under subclass 287. Device provided with means to alter the longitudinal dimension
of the first product cut from a workpiece with respect to the longitudinal dimension
of the remaining products cut from the same workpiece.
| | (1)
Note. The work "crop" is an art term referring
to that end portion of a workpiece which is so irregular in contour
or composition as to be considered waste material. To produce regular
sheets from a rolled slab, for instance, waste or "crop" may
be trimmed from the leading and/or trailing end of the
slab, the intermediate cuts producing the usable products which
are usually of longer dimension than the crop and of similar dimension
as between successive usable products. |
| | (2)
Note. Included herein are patents also disclosing means to
change the length of intermediate products so that a short trailing "crop" end
may be cut. | |
| | |
| 289 | With photo-electric work-sensing means: |
| | This subclass is indented under subclass 286. Device in which the detector includes a means responsive
to light to energize an electrical circuit, and the detection of
work is effected by a change in the quantity or quality of the light received
by said means either directly (as by work"s moving between
said means and the source of said light), or indirectly (as by reflection
from the work).

| | This subclass is indented under subclass 290. Device including a cutter having a means for accomplishing
its feed movement, separate and distinct from a means for accomplishing
its flying movement, whose feed movement (at least) is started by
the work-responsive detector and transmitter.

Note. See (1) Note to subclass 286 for definition of the
terms "feed movement" and "flying movement". | |
| | |
| 294 | With flying work-gripper means related to tool carrier: |
| | This subclass is indented under subclass 293. Device provided with means, connected to and traveling with
the cutter and/or its support, to firmly secure the work
to the support for the period during which the work is moving and the
tool is cutting.
| | (1)
Note. Included herein are patents disclosing devices wherein
a work-responsive flying gripper is actuated to secure the flying
support to the moving work, thus effecting flying movement of the cutter.
Also included herein are patents disclosing work-responsive mechanism to
actuate concurrently a driving means for the flying movement of
the tool and a work gripping means. | |
| | |
| 296 | With means to vary frequency of initiation: |

| | This subclass is indented under subclass 296. Device in which the means to vary the frequency of the tool-action-starting
mechanism includes at least two means, one of said means comprising
an element which, when activated, effects the initiation of the
tool action, the other of said means comprising a plurality of pin members
moving in a closed path, one or more of which pin members along
the closed path may be selectively positioned so as to describe a
second closed path (parallel to the first named path) which intersects
the location of such element at the selected position(s) along the
first named path, whereby the positioned pin member(s) will intermittently
or periodically engage and move, or otherwise activate, the element
in the desired frequency of occurrences.
| | (1)
Note. The positionable pins may be mounted on a wheel or
endless chain for movement in the first named closed path, and any
selected pin may be shifted into the second closed path either manually or
by mechanical means. | |
| | |
| 298 | Interrelated control of tool and work-feed drives: |
| | This subclass is indented under subclass 284. Device in which both the work-feed means and the means to
move the tool through a cutting action or cycle are provided with
independent power trains, each of which trains has a speed changing
means which is adjustable to vary the speed of its driven element
(tool or work respectively), and a common mechanism is provided
to interdependently regulate the several speed changers so that
an adjustment of one will be accompanied by an adjustment of the
other.

| | (1)
Note. A tool pass (as applied in the title and definition
of this and indented subclass) refers to a sweep of the tool along with
the work and including both its flying motion and whatever feed
motion is present. A pass may be rendered ineffective to cut the
work by a change in tool motion (either in its flying or feed movements),
or by a change of work-feed motion, or both. |

through the tool station; the tool, during its passage through the
work, following a path which is substantially perpendicular to the
direction in which the work is moving.
| | (1)
Note. The portion of the work near the cutter may be blocked
thereby during and incidental to the cut, causing a buckling or
compression of the work. If, however, a patent contains a definite teaching
that a dwell is caused in the work motion, such patent will be placed in
subclasses 202+, particularly subclasses 262+.
Usually the tool stroke* is rapid, and the work springs
or falls back to its normal condition between tool strokes. |
| | (2)
Note. For a patent to be placed as an original copy in this
and indented subclasses, it is not necessary that a work-feed means
be claimed if it is evident (from the claimed subject matter) that work
is in motion and that a definite timed relationship exists between
the work motion and the tool actuation. |

upon a portion of the work spaced from the tool and in a direction
not intersecting the cutting zone, whereby the work is caused to
pivot about the portions thereof which are successively engaged
by the tool, to effect a generally curved or irregular line of cut.

| | This subclass is indented under subclass 350. Device provided with work-carrying structure which is drivingly
connected to tool-actuating means so that movement of the work-carrying structure
transmits power from itself to a tool to cause the latter to cut
the moving work.
| | (1)
Note. One tool is sometimes fixed to the work support, and
a cooperating tool moved by linkage connected thereto. |
| | (2)
Note. The concept of this subclass is distinguished from
that of a "flying cutter" by the fact that here
the work may be at rest in the cutting zone at the start of the
operation. Thus the actuated tool of this subclass may have a component of
motion in the direction of the moving work. |
| | (3)
Note. The work-carrying structure constitutes or is part
of work-moving means, hence is distinguishable from a "work-responsive" detector
or sensing means, for which see subclasses 360+. |

| | This subclass is indented under subclass 350. Device including means which constantly transmits power
to actuate the tool continuously through repeated strokes during
continued movement of the work.
| | (1)
Note. A cam-driven tool would satisfy the limitations of
the definition of this subclass only if no dwell period occurs during
the camming cycle. (A dwell period implies interruption in the
flow of power to the tool). |

| 373 | INTERRELATED TOOL ACTUATING AND WORK GUIDE MOVING MEANS: |
| | This subclass is indented under the class definition. Device wherein means to change the location or position
of passive means to orient the moving work cooperates significantly
with means to move a tool through a tool stroke* or a part
of such stroke.
| | (1)
Note. The work guide functions merely in a passive manner
to orient or influence the direction of motion of work which is
moved by another means. |
| | (2)
Note. The generally lateral displacement of work which may
be incidentally caused by movement of work guide means is not considered
work-feeding (work moving) within the definition of this term.
A work guide is thus distinguishable from work-feed means or supplemental
work-feed means. |
| | (3)
Note. The subject matter of this subclass includes a work
guide which is carried by or moved by the tool merely as a matter
of convenience or compactness in design even though its movement
has no effect on the work. |

maintain or retain work stationary, or means to move or render active means
presenting an obstacle or bar to work movement, cooperates significantly
with means to move a tool through a tool stroke* or a part
of such stroke.
| | (1)
Note. This subclass includes a device in which the immobilizer
is merely mounted on the tool or tool support, even though the motion
of the immobilizer may have no useful effect on the work; e.g.,
the immobilizer is movably mounted merely as a convenience or to simplify
the machine design. |
| | (2)
Note. This subclass includes work immobilizers which restrain
and hold work stationary by means of suction, magnetic attraction,
impaling pins, or locating pins, as well as immobilizers which clamp
work or provide stopping abutment therefor. |

| 375 | Work clamp: |
| | This subclass is indented under subclass 374. Device in which the means cooperating with the tool moving
means comprises a plurality of opposed solid jaws or surface elements
which are made effective by movement of one or more of said jaws
or surface elements to grip the work frictionally and hold it in
desired position fixedly with respect to a tool station.
| | (1)
Note. Clamps which act to move the work, as well as hold
it in fixed position after movement ceases, are not found in this
subclass, but will be found in the appropriate subclass relating
to work moving (including those directed to the work-moving, tool-moving
relationship). |
| | (2)
Note. In this subclass are found disclosures of a clamp driven
in timed relationship to a tool as from a common drive shaft or
power train or from a separate power source and related to the tool stroke
only by timing control mechanism. |
| | (3)
Note. For device actuated in timed relationship to a tool,

| 376 | Tool deflected by guide on tightened clamp: |
| | This subclass is indented under subclass 375. Device in which the clamp is slidably mounted on the tool
or tool support by means including a guide which, after the clamp
has been halted by engagement with the work, causes a change of
direction of the tool movement from that in which both it and the
clamp have been moved by the tool driving force.
| | (1)
Note. Examples are found in draw-cutting machines, wherein
inclined guide means between tool and clamp serve to force the tool
away from its initial vertical downward motion after the clamp has
settled firmly upon the work, thereby effecting a slicing or "draw
cut". | |
| | |
| 378 | Clamp driven by reaction from tool force: |
| | This subclass is indented under subclass 375. Device including means to deliver incremental clamping force
in proportion to incremental resistance exerted by the work against
the tool, so that the clamping force (additional to a predetermined
force; e.g., the weight of the clamp) is proportional to the resistance
which the tool meets in its working stroke.

of the reaction of the tool force, in order to deflect the tool
into an oblique, draw-cutting direction. |

| | This subclass is indented under subclass 375. Device wherein proper timing of the tool stroke with respect
to the clamp actuation is assured by provision of means responsive
to a predetermined travel of a clamp jaw or to predetermined developed
clamping force, which means generates a signal or impulse which
causes or permits initiation of a tool stroke.
| | (1)
Note. The sequencing means, as defined in this subclass,
is a specific application of an "interlock" (for
which in general see subclasses 399+). |
| | (2)
Note. Mere timed actuation of clamp and tool in sequence,
as by properly phased cranks or cams, does not meet the definition
of "sequencing means". |

| | This subclass is indented under subclass 375. Device in which a tool is rigidly mounted on or made integral
with a displaceable surface element of the work-gripping means.
| | (1)
Note. Both tools of the cutting pair are movable. One tool
engages the work to clamp it against a work support before the other
tool engages the work in its cutting stroke. |
| | (2)
Note. This subclass includes such devices as split die blocks
which move together to clamp the work before the cutting tool engages
it. |

| | This subclass is indented under subclass 375. Device, in which the actuated tool or its support, in some
portion of its movement approaches and drivingly engages a movable clamp
jaw or element rigid therewith, thus driving the clamp jaw in one
direction only.
| | (1)
Note. The clamp is not mounted on the tool. |
| | (2)
Note. The clamp is usually moved, by engagement with the
tool, against the force of gravity or that of a pre-loaded spring. |

| | This subclass is indented under subclass 383. Device wherein the clamp jaw is moved away from its applied
or work-engaging position by direct engagement with cutter or element secured
thereto.
| | (1)
Note. The clamp jaw is moved against the work by other means,
such as gravity or preloaded spring, when the tool withdraws from
contact with the jaw. | |
| | |
| 385 | Clamp actuating means driven by tool or tool support: |
| | This subclass is indented under subclass 375. Device, in which a tool or an element rigid therewith, during
the tool stroke serves to impart motion to a cam, lever, linkage,
or other force-transmitting means which drives the clamp.
| | (1)
Note. The force-transmitting means in the definition of this
subclass comprehends any mechanical or fluid pressure mechanism
operatively interposed between tool or tool support and movable
clamp jaw, including for example a simple pivoted link connection,
but excluding a direct driving abutment, for which see subclasses
383+. |
| | (2)
Note. A clamp which is moved away from closed (actuated)
position by linkage driven by tool or tool support, and which is
biased or driven toward closed position by other means will not
be found here, but in subclass 375 (or subclasses 388+ for
yieldable drive). Also see (2) Note, under subclass 388. |

| 386 | Clamp yieldably driven by tool or tool support: |
| | This subclass is indented under subclass 385. Device in which the force transmitting means between tool
and clamp comprises a resilient, deformable or slippable element.
| | (1)
Note. See (1) Note under subclass 387. |
| | (2)
Note. The yieldable element may be included in the drive
as a mere safety feature to prevent excessive overload strains,
or it may yield during normal conditions of machine operation, within the
purview of the definition of this subclass. |
| | (3)
Note. A frangible element, such as a shear pin, constitutes
a yieldable drive element for the purposes of this subclass. |
SEE OR SEARCH THIS CLASS, SUBCLASS:
| 388+, | for other examples of a clamp driven, in synchronism
with a tool, through a resilient or slipping drive train. |
|

| | This subclass is indented under subclass 386. Device in which the force-transmitting means comprises an
elastic element (solid or fluid) which exhibits the characteristics
of a spring throughout the expected range of forces applied thereto
during normal operation of the machine.
| | (1)
Note. The definition of this subclass is restricted to drive
means which function in a springlike manner during normal or expected
conditions of operation of the machine. Such means as a preloaded spring,
interposed in a clamp drive train for the purpose of yielding only
to relieve excessive strains during overload conditions, would not
be classified here but in subclasses 386 or 388 as a yieldable drive
element. |

| 388 | Clamp driven by yieldable means: |
| | This subclass is indented under subclass 375. Device wherein the clamp-actuating means comprises a force-responsive
(i.e., resilient or slipping) element forming part of the force-transmitting
train which moves the clamp toward its applied condition, such element serving
to limit the force which can be exerted on and by the movable clamp
jaw.
| | (1)
Note. The yieldable element may be a mere overload responsive
means, not effective during normal conditions of operation.
See (2) Note and (3) Note under subclass 386, supra. |
| | (2)
Note. A clamp which is continually biased toward closed
position, but is raised cyclically by power-driven linkage will
be found in this subclass, even though the linkage is moved by a
tool or tool support. But see subclasses 383 and 385+ for
a clamp biased toward open position and driven toward actuated position,
directly or through linkage, by the tool support. |

| | This subclass is indented under subclass 388. Device wherein the force-responsive element (solid or fluid)
has the characteristics of a spring or its equivalent throughout
the expected range of forces applied thereto during normal operation
of the machine.
| | (1)
Note. The presence of a relief valve in a fluid-pressure
drive means indicates that the drive exhibits the characteristic
of yield ability under certain conditions, hence is not wholly "resilient" (see
(1) Note under subclass 390 and (1) Note under subclass 387). |

or equivalent device subjected to hydraulic or pneumatic force,
and provided with relief valve or other output limiting means.
| | (1)
Note. The disclosure of a relief valve or other out-put limiting
device in the fluid pressure drive system is evidence that the drive
is "yieldable" rather than "positive" or "resilient". | |
| | |
| 391 | Work-stop abutment: |
| | This subclass is indented under subclass 374. Device, in which the means cooperating with the tool moving
means is an obstacle or bar to work movement across the path of
the work which functions by resisting or reacting to the work"s
abutting it.

guide slot below the moving tool and adjacent the work supporting
table. |
| | |
| 399 | OPERATION OF MEMBER CONTROLLED BY MEANS RESPONSIVE TO POSITION
OF ELEMENT REMOTE FROM MEMBER (E.G., INTERLOCK): |
| | This subclass is indented under the class definition. Device characterized by mechanism for detecting the presence
or absence or passage of a portion of the device, or for detecting
the characteristics of a pattern or templet, which mechanism effects
a signal or impulse as a result of such detection and includes a
component (disclosed or claimed) for transmitting such signal or
impulse; further characterized by means to permit or effect the
functioning of at least a portion of said device in response, directly
or indirectly, to the receipt by said means of said signal or impulse;
and further distinguished in that the portion sensed is other than
said part or other than a part or sub-assembly in, or driven by,
a direct drive train moving said part.
| | (1)
Note. In this and the indented subclasses, that part of the
device whose functioning is effected is termed the "member" or "assembly" or "interlock" whose
operation is controlled; the portion sensed is termed an "object" or "element";
and the meaning of the term "remote" (used in
the title) will be elaborated on in (3) Note below. |
| | (2)
Note. This and indented subclasses are the residual subclasses
for the placement of patents claiming means for controlling the
operation of a moving or movable member or assembly or interlock
in response to the sensing of an object other than the controlled,
moving member or assembly or interlock itself. Subclasses 358+,
360+, and 71 to which these subclasses (399+)
are analogous, provide for patents in which the sensed object is
the product, the work, or indicia-bearing control means, respectively. |
| | (3)
Note. Where the sensed object is an element integral with,
or driven by, a direct drive train, which train moves the controlled
assembly, with the result that movement of the assembly is always accompanied
by movement of the sensed element, then the element is part of the controlled
assembly itself, and thus the element is not "remote" therefrom
as required by the title of subclasses 399+. Patents disclosing
and claiming such features will not be placed in these subclasses,
(399+), but will be found in other subclasses of the schedule,
often under the heading "unicyclic", or other equivalent
term. |
| | (4)
Note. This and indented subclasses do not include patents
disclosing structure provided merely with a continuous train of
mechanism inherently operative to perform a plurality of operations, according
to a regular or uniform cycle. For such patents, see other subclasses appropriate
to the desired operations to be performed. |
| | (5)
Note. As a repository of patents this subclass (399) includes
patents disclosing and claiming structure in which the member or
assembly includes mechanism (i.e., an interlock) to prevent movement
of the member or assembly, said mechanism or interlock being provided with
means to disable the movement preventing mechanism, and in which
the sensed object effects the activation of the disabling means,
whereby the mechanism or interlock is released and subsequent movement
of the member or assembly is permitted. For interlock release means
controlled by the presence of the product, see subclasses 358+.
For interlock release means controlled by the presence of work,
see subclass 366. |

| | This subclass is indented under subclass 399. Device including mechanism to start the movement of that
portion of the assembly whose operation is controlled by the sensed
object.
| | (1)
Note. The difference between patents in this subclass (400)
and patents in subclass 399 is that subclass 399 provides for structure
wherein movement of the controlled member or assembly is permitted
(e.g., by effecting release of an interlock), whereas this subclass
(400) provides for structure wherein movement of the controlled
member or assembly itself is started or accomplished as the direct
result of the detection of the sensed object (i.e., element, pattern
or other portion remote from the controlled member or assembly itself). | |
| | |
| 401 | WITH MEANS TO CONVEY WORK RELATIVE TO TOOL STATION: |
| | This subclass is indented under the class definition. Apparatus including (a) dynamic means to effect movement
of the work with respect to the zone of the claimed cutter, or (b)
a device associated and moving with the work to hold or support
the work and facilitate movement thereof with respect to such zone.
| | (0.5)
Note. An extension of a plane from the outer surface of a
cutting edge of a cutter closest to the work will be referred to
as a "plane of cut" or "cutting plane". |
| | (1)
Note. This and indented subclasses are the residual subclasses
for the placement of a patent in which a work-conveying means is
claimed or clearly inferred from the context of the claim and in which
a cutter is claimed. A patents in which work movement is effected
by an operator grasping the work itself and pushing or pulling such
work without correspondingly moving the work-associated device is
excluded from this and the indented subclasses (401+). |
| | (2)
Note. The work-moving means may comprise any structure by
which the work is moved relative to a cutting zone even though the
structure itself may be advanced manually. Examples of such structure
are a moving table, a pusher, a belt, an air-blast nozzle, etc. |

| 403 | Centrifugal feed to tangential tool (e.g., "Beria" type): |
| | This subclass is indented under subclass 401. Device in which the work conveyor comprises a rotatable
disc having a work passageway starting at the center of one of its
faces and terminating in its periphery and in which the cutter has
a cutting plane substantially perpendicular to the disc radius which
defines the axis of the passageway at the moment of cutting.
| | (1)
Note. The patents included herein are commonly known as Beria-type
fiber cutters after the name of the inventor of the device of U.S.
Patent No. 1,723,998. In this and other patents of this type, filamentary
material is led axially into the center of the disc wherein the
material makes a right angled turn into a work passage, usually
radial, and flows through the passage. The rotation of the disc
effects revolution of the radially extending portion of the filament
in the plane of the rotating disc, and the centrifugal force imparted
by the rotation simultaneously effects movement of the filament
outwardly of the axis. | |
| | |

at each of which zones is located a cutter cutting in a plane acting
on a distinct portion of the same material, and including means
to effect movement of said material from a preceding cutting zone
to a succeeding cutting zone in sequence.
| | (0.5)
Note. In this subclass, a plurality of punches or dies which
act simultaneously in a single stroke or cycle of the tool actuator
will be considered as a single cutting zone or tool station: hence, means
to feed to such zone will be found elsewhere in this group of subclasses (401+).
If two punches or sets of punches are positioned at the same general
location, but do not act simultaneously, then the two punches will
be considered to define plural cutting zones and the device will
be found here (404). |
| | (1)
Note. The word "material" as used above
is inclusive of that work which is to be cut at a first cutting
zone, and of that product of the first cutting zone which is work
to be cut at a second cutting zone. |
| | (2)
Note. For further amplification of specific forms of "cutting
zone", see (1) Note of subclass 405, (1) Note of subclass
406, and (2) Note of subclass 407. |

Note. A plurality of slitters transversely spaced at the
same longitudinal location, which slitters simultaneously cut moving material,
(i.e., two or more slitters spaced across the material and perpendicular
to the direction of material movement), will be considered as a
single cutting zone or tool station, whereas slitters obliquely

against the guide. For an adjustable guide, see subclass 421. The
supplemental means may include a pair of rollers inclined to the
path of movement to the work mover, the rollers being driven or
nondriven, but in either case urging the work laterally of the direction of
movement of the work. |
| | (2)
Note. Included herein is a patent disclosing two members
horizontally movable toward each other to clamp work therebetween,
wherein inherently one of the members will engage a workpiece (the
first-engaging member thus being a workmover) and move that workpiece toward
the other member (the other member thus being the additional means);
and in which it is claimed or clearly inferred from the content
of a claim (e.g.,by recitation of "centering" or

Note. Patents placed herein may disclose the function of
the adjustment as effecting a variance of the distance between the
uncut side edge of the work and the cut side edge of the product.
For other patents in which the same function is achieved by shifting
the tool means laterally, see subclasses 433, 498+ and 504. |

| | This subclass is indented under subclass 401. Device including means for urging the work toward the work-moving
means.
| | (1)
Note. Where a patent discloses a pressing member cooperating
in a feeding function (as, e.g., an idler roll of a feed couple),
the patent (to be placed as an original herein) must claim the pressing member
in terms of its pressing function (as by naming it "a presser
roll") or claim additional structure effective to urge
or permit urging of the presser toward the feeding means. |
| | (2)
Note. Included in this subclass are patents in which the
pressure between the presser assembly and the work-moving means
is adjustable. Thus patents claiming a feed couple, or equivalent
term, (characterized by structure including two rolls between which,
and in tangential contact with, the work is moved by the rolls)
and also claiming means to adjust the pressure between the rolls,
will be included in this subclass. |

said means being separate in the direction of movement of the work,
and in which the cutter is located interjacent said means.
| | (1)
Note. If the means located beyond the cutter facilitates
pulling the work through the cutting zone, it is considered to be
a work-moving means for this subclass. For patents in which the
means located beyond the cutter facilitates movement of the product
away from the cutting zone, see subclasses 102+. |

| 425 | Cut made parallel to direction of and during work movement: |
| | This subclass is indented under subclass 401. Device in which a cutter is located at a cutting zone in
the path of moving work and whose cutting plane (as disclosed) is
substantially parallel to said path and to the direction of movement
of the work for constant cutting contact with said work, and including
claimed means for moving the work to and through said cutting zone
for constant cutting of said work.
| | (1)
Note. This subclass includes tools known generally in the
art as "slitters" as well as saws. |
| | (2)
Note. The word "constant" as used above
does not preclude the operation of means to reposition the cutter
out of (and thus, also, back into) the cutting zone in the absence
of work thereat. The cutting is constant so long as (a) the cutter remains
in its cutting position and (b) the work is moved toward and past
it. The following conclusions flow from consideration of this qualification:
| | (i)
The cutter does not have a cycle of operation known as "tool
feed"), in that it does not move to and through the work during
cutting. If the cutter has a movement, its movement is limited to:
(1) a bodily movement of the cutter into a position wherein it will
cut the work, or out of such cutting position, but in either such
case while the work is absent from the cutting zone; or (2) an internal
movement such as will present a fresh cutting edge to the work;
for example, as by rotation of a rotatable circular blade or by
reciprocation of a blade, but in either case while the cutting edge
remains in contact with the work. If the cutter is moved into the
work while the work is at the cutting zone, such movement is part of
a cutting cycle, and a patent claiming such structure is not found
herein. For such patent see subclasses 202+, 284+, and
350+. |
| | (ii)
The work may be, for instance, a succession of relatively
closely-spaced articles, each of which articles is to be cut or slit
longitudinally of the direction of article movement from the leading
end to the trailing end of each article regardless of the orientation
of the article. It also may be a web of indeterminate length, for
instance, which is to be slit longitudinally of its length. | |

| 425.2 | Including plural, laterally spaced tools: |
| | This subclass is indented under subclass 425. Device provided with at least two distinct tools separated
one from the other laterally across the path of moving work.
| | (1)
Note. The tools of this particular subclass are distinguished
from tools of subclasses indented hereunder by the fact that each
tool is separately mounted on its own independent shaft or carrier. |

| | This subclass is indented under subclass 425. Device including means to move the edged cutter, and common
mechanism to drive both the cutter-moving means and the work-moving means.
| | (1)
Note. The cutter movement referred to above is limited to
a movement as restricted in paragraph A of (2) Note to subclass
425. Exemplary forms of such cutter movement are a reciprocation
of the cutter (such as is produced in a "jigsaw" type
of cutter) and a rotation of a disc blade type of cutter. | |
| | |
| 428 | With means to move tool laterally of feed direction during
cutting: |
| | This subclass is indented under subclass 426. Device in which the cutter movement is in a direction which
is simultaneously transverse to the path of the work, and substantially
perpendicular to the cutting plane of said cutter, (i.e., parallel
to a surface of the work), and occurs while the work is moving through
the cutting zone.
| | (1)
Note. Patents placed herein produce an undulant or zigzag
line of separation of cutting. For other patents producing a zigzag
line, but without lateral movement of the tool, see subclass 333. |

tool laterally of the direction of movement of the work. |
|
| | |
| 429 | With means to effect difference between work speed and
tool speed: |
| | This subclass is indented under subclass 426. Device in which the cutter-moving means imparts to the cutter
a component of velocity in the direction of movement of the work,
and including means to cause the velocity of the cutter to be different
in magnitude than the velocity of the work.
| | (1)
Note. Since a reciprocating cutter whose cutting edge is
at an oblique angle to the direction of work movement inherently has
a varying component of velocity in the direction of work movement
as it accelerates and decelerates in its to-and-fro movement, this
of itself is not considered a means to bring about a difference between
the speed of the tool and the speed of the work. However, if a
means is provided to vary the speed of the motion converting mechanism
(which effects the reciprocation of such a cutter) with relation
to the speed of the work, such patents have been placed in this subclass
(429). |
| | (2)
Note. A patent claiming means to rotate the cutter in a negative
direction; e.g., a direction opposed to the movement of the work,
will be found herein. | |
| | |
| 430 | Tool co-axial with work-conveying means: |
| | This subclass is indented under subclass 426. Device in which the means to move work turns about an axis
of rotation and engages work to move the work tangentially of said
means, and in which the cutter is a circular disc-blade turning
about the same axis of rotation.
| | (1)
Note. To be placed herein, a patent must include an edged
cutter and a work-moving roller or disc coaxial with each other.
A tool which is recited in the claim as both a cutting means and
a work-moving means is considered to be a coaxial cutter and work-mover
if it otherwise fits the limitations of the definition. |
| | (2)
Note. A roller serving both as work-moving means and as the
backup anvil for an edged cutter not revolving about such axis is
not itself considered to be an edged cutter. For such structure,
see subclass 434. For similar structure wherein the roller does
not function as a work-moving means, see subclasses 505+. |

cutter located adjacent the edged cutter and acting in a direction
which is simultaneously parallel to the plane of said edged cutter
and perpendicular to the direction of work movement to urge the
work upon the edged cutter. |
| | |
| 432 | Bevel cutting tool: |
| | This subclass is indented under subclass 425. Device in which, as disclosed, the work mover acts to move

face area, and in which the cutting edge of the cutter engages said
face area during cutting.
| | (1)
Note. The structure of patents placed in this subclass is
similar to that of subclasses 505+ and 509+ in
that patents in this subclass may include a rotatable disc-blade
(in subclasses 505+) or a fixed cutter (in subclasses 509+)
engaging the periphery of a cylindrical anvil. The difference is
that in this subclass the cylindrical anvil is rotated by drive means
and is claimed as a work-feed (or equivalent term) means, whereas

| | (1)
Note. The individual patents directed to devices of the type
described in part (A) of the above definition are collected or filed
in this generic subclass (469). |
| | (2)
Note. With respect to part (a) of the above definition, patents
placed herein differ from the patents in Tools, subclasses 651+,
especially disc type, subclass 676, in that the claims of the patents
herein placed include the means about which the tool rotates, whereas tools
in subclass 676 include only the tool and parts partaking of all
the tool movements. For example, if the claimed disclosure includes
a shaft fixed against rotation, about which shaft a disc cutter rotates,
the patent would be placed herein; but if the claimed disclosure includes
a shaft, to which shaft a disc cutter is secured, whereby both elements may
rotate, but no fixed or bearing support for the shaft is claimed,
the patents would be placed in subclasses 651+, especially
subclass 676. |
| | (3)
Note. With respect to part (a) of the above definition, a
holder for so mounting or supporting a rotatable circular member
as defined in the main definition will, in the further description
of this and indented subclasses, henceforth be termed a "Tool
carrier". |
| | (4)
Note. With respect to part (b) of the above definition two
cooperating cutters forming one line of cutting, at least one of
which cutters is a rotatable circular member as defined will, in
the further description of this and indented subclasses, henceforth
be termed a "Tool pair". |
| | (5)
Note. With respect to part (b) of the above definition, the
second cutter may be a disc-blade similar to the circular cutter
defined, or may be a section of a circular cylinder (the disc-blade
cooperating with the peripheral surface of the cylinder, see subclass
505 for example) or may be a flat anvil surface or ledger blade
edge across which the disc-blade moves, (see subclasses 485+ for
example), or may partake of nonrotary movements or no movement (see
subclass 508 for example), or may be any other part with which the
disc-blade as defined cooperates to cut work thicknesswise. |
| | (6)
Note. With respect to part (b) of the above definition, (i.e.,
Tool pair), the definitions of the subclasses indented hereunder
are written in terms of one tool pair, that is, one disc-blade cutter cooperating
with one backup element (anvil, cylinder, other-disc-blade, etc.) whereas
as disclosed and claimed there may be a plurality of disc blades
on a common axis (or, in the case of a cylindrical anvil of subclass
505, a single anvil having a peripheral surface common to plural
discs against which surface all of the disc-blades are in cooperative
relationship). |

or against a radial force exerted by the cutter action on the work.
| | (1)
Note. For a patent to be placed herein, the work-supporting
function of a table or other element must be recited in the claim
or be clearly inferred from the context of the claim. For patents
in which a table is claimed as supporting a guide for a tool carrier,
see subclasses 485+. |

substituted.
| | (1)
Note. For a patent to be placed herein, the cutter removal
function of the carrier must be recited in the claim or be clearly inferred
from the content of the claim and supported by the disclosure. |
| | (2)
Note. Since it is inherent in a device wherein the cutters
of a tool pair are separable, as exemplified by the patents of subclass

| | (2)
Note. To be classified herein, a patent must include disclosure
of a movement of one cutter away from and out of cutting relation
with respect to the other cutter of the tool pair (this movement usually
being for the purpose of permitting the work to be threaded through
a cutting zone). A mere adjustment of one cutter relative to another
cutter while they remain in contact with or in cooperative cutting
relationship with each other will not suffice for placement in this
subclass, but will be found in subclasses 503, 504 and 507 below. |

Note. Included in this and indented subclasses are patents
reciting carrier means for holding or mounting the cutters, for example,
a separate carrier for each cutter or a carrier common to both cutters. | |
| | |
| 496 | Tool pair elements angularly related: |
| | This subclass is indented under subclass 495. Device in which the axes of the cutters are not parallel.
| | (1)
Note. In the patents placed herein the angular relationship
is rarely recited precisely as exemplified below, but this relationship
usually falls into one or more of the following categories or types:
| | (a)
the cutter axes lie in a common plane, but the axes are not
parallel to each other, hence the axes converge to a common point; |
| | (b)
the cutter axes lie in planes which are separate, not in a
common plane, but are in planes which are parallel to each other; |
| | (c)
the cutter axes lie in planes which are separate, not in a
common plane and not parallel to each other. A distinguishing feature
of all the patents placed herein, or in the indented subclass, lies
in the fact that the cutter axes, if projected (in the sense of
the term as used in descriptive geometry) on to a common plane, will
intersect. | |

| 861 | OTHER THAN COMPLETELY THROUGH WORK THICKNESS OR THROUGH
WORK PRESENTED: |
| | This subclass is indented under the class definition. Method or apparatus utilizing a tool which: (a) is disclosed
as limited to engage operatively only one of the nonthickness work surfaces
(and which may or may not engage operatively a thickness work surface),
or (b) has operative (i.e., cutting) engagement with only a thickness
face and which is constrained to an operative path lying between
the nonthickness faces, or (c) has a tool stroke* in a single
rectilinear path, which stroke fails to completely cut all the work
lying before it in the direction of its cutting path (even though the
resulting line of cut may extend entirely through the thickness
of the work).
| | (1)
Note. A thickness surface is one along which the "work
thickness" may be measured. See the illustration below.
"Nonthickness Surface"; "ThicknessSurface"; "Work Thickness Dimension" |
| | (2)
Note. For a patent to be placed originally in this or indented
subclasses, it is not required that the contemplated type of cutting
be distinctly claimed. It is sufficient that the claimed means
be disclosed as functioning within the limitations above defined. |
| | (3)
Note. Where the tool operates to produce a mere indentation
or distortion of surface material (i.e., without severing the work
surface fibers), as for instance, by creasing, forging, or metal
rolling, or combines cutting with a significant material flow, as
for instance in sheet forming and in plastic working, then the patent
for such defined subject matter is excluded from this class and
will be classified in other classes according to material worked
on, type of operation performed, or machine disclosed. |
| | (4)
Note. Where the disclosed apparatus is directed to subject
matter as above defined but the claimed recitation is limited to
a cutter, per se, then the patent for such is originally placed
in a subclass of tools, per se (651+). |
| | (5)
Note. Where a tool element penetrates partially through the
thickness of a workpiece and thereafter continues to coact with
an opposed tool element, which opposed tool element completes the
severance of the workpiece in the cutting plane extended of the
first tool, then the combined cut through the work is considered
the same as the product of a single coacting tool pair and the patent directed
to such subject matter is excluded from this subclass and those indented
thereunder and will be found elsewhere in the schedule. However,
if the first said tool is withdrawn from the workpiece before the
complete severance occurs (i.e., no coaction occurs between said
elements) then the first tool element is considered to be a scorer means
and the opposed tool element a through cutter, and a patent disclosing same
is placed as an original copy in this or indented subclasses. |
| | (6)
Note. The main body of the class (subclasses 13+)
always should be included in the search for a particular process,

Note. Excluded from this subclass is a patent for a process
or apparatus for merely slitting such a junction area, as the operation
of slitting itself is not considered to entail removal of a work
portion. However, a patent may properly be placed herein where
a plurality of slitters coact to remove a portion of edge material. |
| | (2)
Note. In general, the patent of this subclass discloses removal
of a work portion planarly by a single tool. However, a patent directed

CROSS-REFERENCE ART COLLECTIONS
The following subclasses are collections of published disclosures
pertaining to various specified aspects of the cutting art which
aspects do not form appropriate bases for subclasses in the foregoing
classification (i.e., subclasses superior hereto in the schedule),
wherein original copies of patents are placed on the basis of proximate
function of the apparatus. These subclasses assist a search based
on remote function of the apparatus and may be of further assistance
to the searcher, either as a starting point in searching this class
or as an indication of further related fields of search inside or
outside the class. Thus, there is here provided a second access for
retrieval of a limited number of types of disclosures.
