CLASS 410,	FREIGHT ACCOMMODATION ON FREIGHT CARRIER
Click here for a printable version of this file

SECTION I - CLASS DEFINITION

A. This is the generic class for the accommodation of discrete units of freight which have been loaded on board a freight carrier for transportation, the freight accommodation being to assure the integrity of the load unit against the hazards of dynamic forces incident to transit

The class comprehends:

Means, entitled "accommodating means" in direct contact with a load unit to inhibit untoward shifting relative to the carrier that would be hazardous to the integrity of the unit. The term "accommodating means" is the generic term therefor.

Load unit accommodation on a freight carrier is recognized by the provision of:

1. An accommodating means detail in the construction of the load-supporting section of a freight carrier;

2. Means, per se, installable or otherwise put to use on a freight carrier (like dunnage which is merely inserted between load units);

3. Particular means on an exterior surface of the load unit (usually, of the load bearer type) itself; particularly provided, that is, to contact and thereby to cooperate with a corresponding construction of the freight carrier to achieve the accommodation of the load unit thereon;

4. An arrangement of an article of freight or the grouping of articles in such a way or to assure the integrity of the load against untoward shifting on board the freight carrier. Accommodating means may, but need not necessarily be required nor used to effect the arrangement; or

5. Freight accommodating methods, namely (a) associating a load unit present on the freight carrier with the appropriate accommodating means or (b) arranging (e.g., grouping) a load unit on the freight carrier.

(1) Note. Cautionary note: A step of loading onto or of unloading a load unit from a freight carrier places the combination beyond the limits of this class; for which greater combination see the material or article handling class. B. Present the critical element of load unit accommodation as herein defined, placement in the class is on a predominant disclosure basis. An invention will be found herein when the subject matter of the invention, regardless of breadth is disclosed as: 1. A support or receptacle which has a use as a freight carrier vehicle body part, e.g., an on-and-off container or other load bearer provided with the accommodating means referred to above. 2. Article securing or bracing structure which in use is attached to, installed on, or even merely placed on board a freight carrier for freight accommodation (e.g., dunnage). 3. Structure concerning which the advance in the state of the art has caused to be recognized as uniquely suitable to freight accommodation on a freight carrier. The emphasis in the disclosure of load unit accommodation on freight carrier for this class should be on a level equivalent to a principal embodiment description. However, as to the state of the art test, a presumption of load unit accommodation on a freight carrier not negated in the disclosure will serve for inclusion of the document in this class (410). In fact, except where clearly negated by the detailed description, this class is available as a depository for such state of the art structure as dunnage structures for load bracing and twist lock devices for load bearer retention even when not pinpointed in the description for use on a freight carrier. 4. A load bearer which is a shipping support on which a single article is secured for on-and-off stowage aboard a freight carrier. This subject matter is provided for in this class, even when the shipping support load bearer does not include the accommodating means cooperating with the freight carrier. This is so because the state of the art recognition of the equivalency in the art of the shipping support load bearer, whether or not provided with such cooperating means, has become so integrated at the time of the inception of this class (410) that the search for both has been quite merged.

(1) Note. Cautionary note: A shipping support lacking the accommodating means and supporting a group of articles on a freight carrier has not been classified in this class (410) but will be found elsewhere. A freight container absent the accommodating structure cooperating between the container and the freight carrier will also be found elsewhere. See References to Other Classes. A term which is defined in this class (410) definition, and is limited to a single word, is identified by an asterisk. Where a group of words defines the term, parentheses are used to identify the beginning and end of the term; and this is followed by an asterisk.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

INTERNAL PLAN OF THIS CLASS

A. Class 410 consists of three major groupings, as follows:

1. Particular Article Accommodation, (see Subclass References to the Current Class, for the location of the definition of this term) - subclass 2+

2. Load Bearer Accommodation, (see Subclass References to the Current Class, for the location of the definition of this term) - 52+

3. Subcombinational Subject Matter, namely (a) Load Lashing - 96+; and (b) Load Bracing, i.e., Yieldable Brace - 117+, and Load Bracing - 121 (generally). (see Subclass References to the Current Class, for the location of the definition of these terms)

The accommodation to the shape of the particular article in this first group being of essence and the disclosure being almost inevitably to such a detail, inventions limited to the subcombination will nevertheless be uniformly classified in that superior locus (subclasses 2+) and will be found as a cross-reference only in the subcombinational loci, subclasses 96+ or, in particular, subclasses 117+ and 121+.

B. Search Time And Storage Economization: Search Units.

1. Economy in search time and retrieval efficiency and in search area storage space has been incorporated in the internal plan of this class. This was done by the abstraction from the more generalized art of some particular subclasses certain subjects matter meriting low priority as the depository of the original (as opposed to the cross-reference copy) of a document in the classification schedule. As a result, subclasses of such low priority subject matter recur as indents under classified loci of higher priority (typically as subcombinations in different superior and separately classified combinations). Recurring sets of extractions or "break outs" have thus been developed out of separate but mutually related indented subclasses. They are usually quite small. A one "break out" readily matches a second (sometimes also a third) freed from the disclosures in principal subclasses entirely extraneous to the particular search needs for which "search units" have been devised.

2. Search Units: Where these "break out" pairs (or triplets) most closely coincide in extensiveness and analogousness further economy is achieved by emphatic discouragement of cross-referencing internally of one another but rather, are singled out and can be identified as constituting search units. They are easily recognized and identifiable in the Class 410 schedule.

3. The vehicle classes: The vehicle classes involved in the haulage of freight, absent the freight accommodation feature(s) as defined in section I, above, are:

RELATIONSHIP TO THE VEHICLE CLASSES

The vehicle classes involved in the haulage of freight, absent the freight accommodation features as defined in the Class Definition, above, are found in References to Other Classes below.

Excluded from this class (410) are (a) haulage of material in bulk, whether fluid, aggregate, particulate or in any bulk form. However, a rigid-wall receptacle which contains fluent or other bulk material qualifies as a load unit (of the load bearer type) for this class (410); and (b) very short distance movement of articles on a vehicle propelled by a walking attendant handler (e.g., from a building to a moving van); for which see References to Other Classes, below.

Securement means for articles on a pleasure vehicle for the pleasure or convenience of the occupant(s), particularly, are provided for elsewhere.

RELATIONSHIP TO THE RECEPTACLE AND SUPPORT CLASSES:

The receptacle and support classes include disclosures for the provision of securement or bracing of an object or of a group of objects intended for shipment together as a unit, but excluded from the instant class (410) because of absence of accommodating means cooperating with a freight carrier. The receptacle classes of this description may be found in References to Other Classes below.

The support classes are found in Reference to Other Classes, below.

The receptacle and support classes are in particular related to subclass(es) 52+ of the instant class (410) in that a receptacle or support is recognized as a load bearer when conforming to the limitations set forth in the Class Definition; i.e., having means cooperating with a freight carrier to effect the accommodation thereof on the freight carrier. Placement in the instant

Class 410 is in no way barred because of further inclusion of details of receptacle or support structures. This class is the appropriate locus too, for a receptacle or support disclosed as being, in fact (a) a freight carrier body part, and (b) provided with accommodating means for a stowed load unit, e.g., the particular article under subclasses 2+.

RELATIONSHIP TO ARTICLE HANDLING CLASSES

See References to Other Classes for the generic article handling class, which provides for the means and method of loading and unloading freight on-and-off a freight carrier.

See References to OTher classes for article handling classes that provide for means for tautening flexible material about a load of objects--absent the attachment of the load to the freight carrier--and that provide for container lift loading and unloading devices of the spreader frame type. (This type lift device includes latch elements akin to the retainers of of the instant class (410), particularly akin to the twist lock type found in Class 410).

RELATIONSHIP TO ATTACHMENT DEVICE SUBCOMBINATIONS, ELEMENTS:

See REferences to Other Classes, below, for attachment devices used to secure objects to one another only, to make up a load unit found on a freight carrier, but which devices do not couple the load unit to the freight carrier.

Class 188 Brakes, subclass 32 is the generic locus for a wheel chock, recognized as a brake on the ground whereas the instant Class 410 is the locus for such a device used on board a freight carrier to stabilize freight; compare with instant Class 410, subclass 30 for a wheel chock for a stowed vehicle; and subclasses 49+ for a chock for stowed cylindrical article, generally. Compare, too, with instant subclass 62 for fore-and-aft accommodation of a stowed vehicle where the aft-end accommodating means may be a wheel chock. (Attachment Device Class)

RELATIONSHIP TO STOCK MATERIAL CLASSES

The locus for members of indeterminate shape, as for load bracing, e.g., dunnaging, is found elsewhere. When in fact of such a shape so as to be beyond the scope of that class, a bracing member will be found in the instant class (410) in subclasses 117+ when of flexible (i.e., flexible wall) material; subclass 121 being the principal subclass for load bracing; and subclasses 154 and 155 for, respectively, edge around and honeycomb dunnage. Subclass References to the Current Class of this class (410) is particularly relevant as a guide to the location of dunnage in the instant Class 410. (Stock Material Class)

SECTION V - GLOSSARY

Also see Subclass References To The Current Class, above, for the location of the definition of other Glossary terms.

CUSHIONING MEANS:

Fore-and-aft slide cushioning means - Load unit protection means supplementing load accommodation. The effect of inadvertently inertial forces which could cause damage to the load unit is mitigated by means so supplementing accommodation as to permit such an extent of reactive movement of the load unit or the accommodating means, or both as to be adequate to prevent damage that could occur were the load rigidly fixed to the freight carrier. When the forces guarded against and the reactive movement acts in the direction along the longitudinal axis of the freight carrier, this is recognized as fore-and- aft direction slide cushioning. The effect of only mere compression-relaxation of a resilient block is not intended to be included in the cushioning concept.

LOAD LASHING RETAINER

Retainer which includes flaccid material accommodating means, the virtue of the flaccidity being in its infinite deflective capacity so that the means can (inter alia) (a) closely conform to exterior configurations of load units, (b) extend in guided changes in direction from the locus of securement to the freight carrier to that of the retentive engagement with the load unit, and (c) most particularly, under subjection to force multiplying means, be so tightly engaged with the load unit, and over such critical configurations of the load unit surface that the engagement of this nature constitutes load unit retention. A load lashing retainer may consist of a combination of rigid material and flaccid material elements provided that the flaccid material element (or member) is significant in the combination. Significance is present when the flaccid material element member is used (a) to attach the load lashing retainer to the freight carrier or retentively to connect with the load unit, or (b) to extend between the freight carrier attachment member and load unit securement member (one or both of which members are rigid) to impart to the load lashing retainer made up of these members unique advantages of flaccidity described in the preceding paragraph. Not all flaccid load unit accommodating relationships are, in fact, retentive. Tight encirclement of the load (i.e., wraparound lashing) tautened engagement with the load under the effect of force multiplying means, and a tiedown (defined hereinbelow) do, however, invariably accomplish load lashing retention.

TIE PIECE

The anchor part which directly engages the end of a flaccid material member to secure that end at an anchor location whereby to define the point from which the member diverges from the freight carrier surface. The term is used in the context of bi-partite construction in that the tie piece is an add-on (e.g., welded on) part, the other part of the anchor being the mounting for freight carrier attachment. Commonly, the mounting is a one-piece member shaped or otherwise so constructed or arranged on a freight carrier as to define an array of anchor locations, at one or more of which the add-on tie piece is attached. See Subclass References To The Current Class, above.

TIEDOWN

A load lashing retainer which diverges from the freight carrier surface whereat it is attached and extends and terminates at the point or localized area of attachment to the load units.

SUBCLASSES

1	INCLUDING TURNTABLE FOR LOAD, E.G., FOR SEMITRAILER:
	This subclass is indented under the class definition.  Structure in which the freight carrier has a supporting surface which is rotatable to turn lading which it underlies (typically, a semitrailer or other wheeled vehicle for transhipment) between positions (a) for loading and unloading, and (b) for transit aboard the freight carrier.

2	PARTICULAR ARTICLE ACCOMMODATION:
	This subclass is indented under the class definition.  Structure for accommodating, by direct contact, an article of the type which satisfies a particular need elsewhere (i.e., is not merely a bearer for the load in shipment, like a container or pallet), which structure is designed, in its contact with the lading, to take advantage of a particular configuration of the lading, or one of its parts, to minimize a carrying problem arising from such particular configuration, e.g., tendency of a cylindrical article to roll. (1) Note. Included herein (see indented subclasses 31+) is the accommodation of articles by their having been grouped in a particular way or by having been otherwise so arranged on the freight carrier that a foreseeable problem in transit is minimized. (2) Note. The class definition section, Internal Plan of This Class relating to this and the indented subclasses is reviewed, as follows: placement in this and indented subclasses is on a predominant disclosure basis, which means that, in the absence of a controlling claim barring such placement or an overwhelming emphasis in the total disclosure to that same effect, this is the locus (subclasses 2+) for the original placement of an invention to accommodating means for the particular article. Accordingly: a. A generic invention to structure disclosed as accommodating a semitrailer or container (ordinarily classified under subclasses 52+) and equally applicable to the accommodation of a particular article (a farm tractor in transit, for example) will be classified as an original in subclasses 2+ and will appear in subclass(es) 52+ only as a cross-reference where necessary. b. Subclasses 2+ will take an invention to a load lashing means or load bracing means subcombination for a particular article or group of articles and only a cross-reference will be placed in subclasses 96+, load lashing, or subclasses 121+, load bracing means; the locus for the lashing or bracing subcombinations, respectively, of general freight. SEE OR SEARCH THIS CLASS, SUBCLASS: 35, for a group of articles stowed on board a freight carrier together with an on-and-off base. 46, for a shipping support onto which a single article only has been secured for on-and-off storage on board a freight carrier.

(1) Note. This (the principal) subclass includes inventions for bicycle stowage. (2) Note. Semitrailers are presumed to be load bearers, not, in themselves, particular articles of freight. SEE OR SEARCH THIS CLASS, SUBCLASS: 56+, for the stowage of freight-laden semitrailers.

4	Four-wheeled vehicle accommodation:
	This subclass is indented under subclass 3.  Structure in which the freight carrier is particularly designed or equipped to accommodate such a wheeled vehicle as has sets of running gear from corner-to-corner across the forward and the rear ends. SEE OR SEARCH CLASS: 206,  Special Receptacle or Package,   subclass 335 for a four-wheel vehicle or group of vehicles preassembled in an on-and-off container for shipment on a freight carrier, absent means for interengagement with the freight carrier for accommodation against the hazards of transportation.

	This subclass is indented under subclass 5.  Structure including panel means constituting a vertical panel at the side edge of the freight carrier and mounted for swinging movement outboard thereof for rolling or placement of a vehicle thereonto for stowage, and means for securing the vehicle to the panel whereby, when the panel is then swung to its vertical position upward from the edge of the carrier the panel means further functions to sustain the stowed vehicle attached thereto at substantially 905 to its normal road use attitude.

7	Vehicle retainer*:
	This subclass is indented under subclass 4.  Structure including a retainer*; i.e., member(s) secured to the carrier and particularly constructed for direct securement engagement with a part of the stowed vehicle

8	Multipositionable; i.e., along array strip or track:
	This subclass is indented under subclass 7.  Structure in which the carrier is further provided with an elongated mounting member which has retainer positioning locations therealong; and in which (a) the retainer engageable with the stowed vehicle part extends from the location selected as being the suitable one for retaining the vehicle on the freight carrier, or (b) the elongated mounting member is shaped to guide the vehicle retainer for sliding movement therealong to the selected location.

(1) Note. Accommodating structure such as a straddle or cradle does not constitute retentive securement where only the lower wheel quadrant is engaged; whereas retention amounting to securement necessarily is effected when similar structure encompasses the upper wheel quadrant(s).

17	Including suspended retainer* member or prop:
	This subclass is indented under subclass 13.  Structure in which the freight carrier is a walled vehicle and in which an elongate arm or flexible means depends from substantially the highest portion of the carrier interior either (a) to bring a retainer* member into its direct, retentive contact with a vehicle part, or (b) to abut and thereby brace either the retained vehicle or some part of the retainer*.

25	Interrupted or recessed wheel support:
	This subclass is indented under subclass 24.  Raised vehicle arrangement structure in which spaced supporting portions or members engage respective lower quadrant portions of a stowed vehicle wheel perimeter, whereby the intervening perimetral portion, which normally sustains the vehicle mass, as during road use, is uncontacted by said member or portions. (1) Note. Another sunken and upwardly concave member may, however, span the space between the member or portions to substantially conform to and contact the lower half perimeter of the wheel. SEE OR SEARCH THIS CLASS, SUBCLASS: 26, for a raised vehicle arrangement wherein the underlying support, in the raised vehicle arrangement, is planar so as to contact the vehicle wheel at that point at which it normally sustains the vehicle mass. 30, for wheel chock or cradle means to inhibit the rolling tendency of a vehicle wheel. 49+, for similar means to inhibit the rolling tendency of any other cylindrical article. 57, for the fore-and-aft accommodation of a semitrailer which could include similar sunken area structure for accommodating the rear wheels. 65, for a rear wheel accommodating sunken area accommodating the stowage of a semitrailer.

	This subclass is indented under subclass 26.  Structure including further structure underlyingly receiving the vehicle wheel(s) thereupon and constituting either an elevator or inclined ramp for transit of vehicles between the vertically spaced decks. (1) Note. Elevating structure, per se, and nothing more, is proper for this subclass only when, either in itself or together with another elevator(s), it provides a substantially continuous elevated support for a plurality of vehicles at least temporarily, for loading and unloading. The elevator or ramp must be in addition to, and for service between, a plurality of decks level. Absent the above, see principal subclass 26 for an inclined fixed height structure sustaining the four-wheels of a single stowed vehicle and subclasses 14+ for such a structure which is adjustable, e.g., elevatable.

28	On dropped-center car:
	This subclass is indented under subclass 27.  Structure in which the freight carrier floor which underlyingly supports the vehicle wheels is of an extent to include a center area lower than the freight carrier running gear supports and another area extending therefrom to a level to support a part, at least, of a stowed vehicle directly above a running gear support.

28.1	On dropped section freight carrier:
	This subclass is indented under subclass 26.  Structure in which the freight carrier floor includes longitudinally contiguous areas, namely, a relatively high area at an end section of the freight carrier and a relatively lower area longitudinally inward thereof, whereby a vehicle may be towed athwart the areas at an incline with respective ends thereof supported at the corresponding floor areas. (1) Note. The freight carrier of this subclass is of the type which is wheeled and is for highway travel and includes a floor section inward of the running gear used to advantage in freight haulage in being constructed lower than the running gear height. (2) Note. The stowed vehicle may be supported, front and rear, directly on respective floor sections, or on structure supported by and straddling the floor sections.

29	Vertically swingable from hinge at freight carrier wall:
	This subclass is indented under subclass 26.  Structure in which the deck structure is pivotally mounted at the freight carrier wall for vertical swinging movement. (1) Note. The hinged deck structure may include a plurality of members, of which each, or a pair of each extends from opposite walls of the freight carrier for supporting corresponding pairs of the supported vehicle wheels.

29.1	Higher level deck positioned, then sustained by power cylinder:
	This subclass is indented under subclass 26.  Structure in which the member which underlyingly supports the stowed vehicle by its wheels is vertically adjustable and in which piston and cylinder telescoping tube means has one end attached to the member and the other end to a point on the freight carrier, the telescoping tube means being subject to the influence of force from a fluid source to effect elongation thereof to position the wheel support member at the requisite height, or attitude at which the piston and cylinder means cooperates in retaining the vehicle support means.

30	Wheel cradle, chock, or well:
	This subclass is indented under subclass 4.  Structure wherein the means to accommodate the stowed vehicle engages the wheel(s) thereof at location(s) extending to, but not beyond both lower quadrants of the wheel periphery; or along, but not beyond, a substantial perimetral length of a lower wheel quadrant. SEE OR SEARCH THIS CLASS, SUBCLASS: 49, for cradle structure accommodating a cylindrical article other than a wheel mounted on a vehicle. SEE OR SEARCH CLASS: 188,  Brakes,   subclass 32 for a chock, recognized as a brake on the ground for that class and subclass, and which may be used to chock a vehicle wheel on a surface other than that of a freight carrier.

31	Grouped:
	This subclass is indented under subclass 2.  Structure particularly designed for accommodating a number of articles as a load unit, or an arrangement of such a number of articles. (1) Note. This (the principal) subclass includes inventions particularly designed for accommodation of groups of engines, also racks or hanging hooks for meat carcasses. SEE OR SEARCH CLASS: 206,  Special Receptacle or Package,   appropriate subclass for a group of articles which is prepackaged possibly for stowage as a load unit on board a freight carrier.

32	Group of articles which are, predominantly, regularly contoured; i.e., are rodlike, panel shaped, blocks, or analogous forms:
	This subclass is indented under subclass 31.  Structure or arrangement wherein the accommodated load unit consists of articles which are substantially the same in cross section throughout at least nearly all of their length. (1) Note. The article, under the instant definition, may have a localized irregularity (for which, see subclass 31, indented hereunder) but remains, on the whole, "predominantly" regularly contoured, as the title to this subclass phrases it.

33	Articles with protuberance or flange:
	This subclass is indented under subclass 32.  Structure or arrangement particularly designed to establish a load unit of articles shaped with a localized right-angled extension from each of their otherwise regular contours.

34	Grouped by load binder or press means
	This subclass is indented under subclass 32.  Grouped by load binder or press means: Structure including means firmly forcing the articles into compact proximity. (1) Note. The means of this subclass may be firmly forced against the group of articles by muscle power or by force multiplying means associated with said first-named means (for which latter, see indented subclasses 38+). SEE OR SEARCH CLASS: 24,  Buckles, Buttons, Clasps, etc.,   subclasses 16+ for a wraparound load binder for a group of articles having no parts connected to a freight carrier; see, too, indented subclasses 19+ wherein the load binder includes a tightener; and see subclasses 68+ for a tightener, per se.

35	Grouped together with on-and-off base:
	This subclass is indented under subclass 34.  Structure further including underlying support structure for the load unit and united therewith by the load binder or press means for and throughout the loading and unloading sequences. (1) Note. A rigid member underlying a load unit may be merely an element of the press means of principal subclass 34 when its dimensions are not substantially different from the remaining (side and top) press means member; rather than being so substantially dimensioned as to be clearly recognizable as a supporting base for the load unit. SEE OR SEARCH CLASS: 206,  Special Receptacle or Package,   subclass 386 for a group of articles prepackaged on an on-and-off base for stowage for shipment on board a freight carrier, absent means in interengagement with the freight carrier for accommodation against the hazards of transportation.

36	Cylindrical article group:
	This subclass is indented under subclass 34.  Structure in which the means firmly maintains or urges articles of substantially circular cross section into the compact proximity.

37	Log load:
	This subclass is indented under subclass 36.  Structure or arrangement in which the load unit consists of hewn tree trunks in compact proximity.

40	Between groups:
	This subclass is indented under subclass 39.  Structure in which the intervening means is between and sets off one group of articles from another.

41	Including angle overlay, e.g., corner guard:
	This subclass is indented under subclass 34.  Structure in which the articles of the group are of such shape that the group is configured as to provide an abrupt, substantially 905 change of direction along the outside surface of the group; and in which a rigid member is of such shape as to be in overlying contact with said outside surface through said change in direction. (1) Note. In this way, frequently, the outside corner article is protected from the bend of a taut lashing member.

42	Cylindrical article group:
	This subclass is indented under subclass 32.  Structure in which the accommodated load unit consists of articles of substantially circular cross section.

43	Vehicle body part group:
	This subclass is indented under subclass 31.  Structure or arrangement particularly designed to accommodate articles consisting of frame or shell parts for vehicle manufacture or assembly.

44	Accommodation of article which is massive relative to the freight carrier:
	This subclass is indented under subclass 2.  Structure particularly designed to accommodate a single article (a) of such dimensions as to occupy substantially the entire space of the freight carrier or to extend beyond an edge thereof (e.g., onto a second carrier), or (b) of such height as to require that the freight carrier load-support area surface area on which the article rests be between and lower than the height of the top of the carrier trucks. (1) Note. A truck is considered to be a freight carrier for this subclass so that an article bridging a pair of trucks are properly classifiable therein. The article may in itself, or together with on-and-off base, be the sole structure bridging the pair of trucks; for which see indented subclass 45.

45	Stowed as a bridge between trucks, or across cars, or on drop-center (schnabel type) car:
	This subclass is indented under subclass 44.  Structure or arrangement (a) in which the article, either by itself alone or together with an on-and-off underlying support, is mounted at each end onto separate, spaced apart freight carrier running gear structures to constitute the sole connection between those structures while so mounted, or (b) in which the article staddles a plurality of horizontally swingingly related freight carriers, or (c) in which the freight carrier load-support area is between and lower than the height of the freight carrier running gear supports. (1) Note. With respect to part (b) of the above definition, each of the separate spaced running gear structures (i.e., trucks) constitutes, in itself, a freight carrier and the article, extending from the one to the other extends beyond either one of them. The requirement for placement in subclass 44, under (1) Note of the definition thereof, is there­ by met. SEE OR SEARCH THIS CLASS, SUBCLASS: 53, for a load bearer, e.g., semitrailer, stowed as a bridge between trucks. SEE OR SEARCH CLASS: 296,  Land Vehicles: Bodies and Tops,   subclass 25 for a dropped center highway vehicle, e.g., semitrailer, absent the provision thereon of load accommodating structure.

46	On supporting on-and-off base:

47	Cylindrical article accommodation:
	This subclass is indented under subclass 2.  Structure particularly designed to accommodate an elongate article of substantially circular cross section; i.e., to utilize a structural feature of, or nullify a particular problem inherent in, the shape of the article.

	This subclass is indented under subclass 47.  Structure including rigid means retentively engaging the article along its longitudinal axis, or retentively engaging a member axially related to (generally, an axial part of) the article.

49	Cradle or chock:
	This subclass is indented under subclass 47.  Structure in which the accommodating means defines an upwardly facing concavity or upwardly diverging angle(s), whether continuous or interrupted, in either case to engage one or both lower quadrants of the cylindrical article periphery and thereby inhibit rolling. SEE OR SEARCH CLASS: 188,  Brakes,   subclass 32 for a chock recognized as a brake on the ground for that class distinguishing over the instant subclass in that it is applied to a surface other than that of a freight carrier.

50	And wraparound* lashing:
	This subclass is indented under subclass 49.  Structure further including a wraparound* (load lashing retainer)* attached at its ends to the freight carrier and drawn securely about or through the article to secure it against a contour-complementing surface of the accommodating means. SEE OR SEARCH THIS CLASS, SUBCLASS: 20, for a wraparound for securing the wheel of a stowed four-wheel vehicle to the freight carrier; and subclasses 97+ for a wraparound for lashing a load unit to a freight carrier, generally.

51	DRAFT (INCLUDING PUSHED) FREIGHT CARRIER, I. E., WAGON, HAND TRUCK:
	This subclass is indented under the class definition.  Structure particularly designed to accommodate a load unit on a freight carrier the motive force for which is intended to be entirely biologically muscular. (1) Note. Included herein are horse drawn wagons designed for such facile removal of the load bearer structure from running gear as is common to the more contemporary load carrier stowage technology of subclasses 52+. Because of such commonality that has been brought about by the advance in the state of the art, this type of support or container is classified with more contemporary on-and-off load bearers of this class (410). SEE OR SEARCH CLASS: 280,  Land Vehicles,   subclasses 47.131+ for an inherently unstable vehicle to which an article may be attached, and which may be propelled by a walking attendant. Transportation (a) for a insignificant distance, as within a supermarket or from a building to a curbside moving van, or (b) by a noncommercial user, e.g., a shopper or a boatman trailering his own boat would be appropriate for that Class 280, subclass 47.131 rather than the instant class and subclass 51.

52	LOAD BEARER ACCOMMODATION:
	This subclass is indented under the class definition.  Structure particularly designed to accommodate an on-and-off freight support base or receptacle; i.e., such as underlying support or such an enclosure as presumably receives freight thereon or therein prior to being loaded on the carrier and is unloaded from the carrier together with the freight. (1) Note. A base (pallet) or enclosure (container), per se, is herein included when provided with externally carried means specifically for cooperation with mating means on the freight carrier for the accommodation of said base or enclosure and will be found in the particular subclass provided for that particular accommodation. The means, per se, specifically for cooperation with mating means on the freight carrier for the accommodation of said base or enclosure and will be found in the particular subclass provided for that particular accommodation. The means, per se, found in subclasses 96+ is also herein provided. SEE OR SEARCH CLASS: 294,  Handling: Hand and Hoist-Line Implements,   subclasses 67.1+ for a frame or a load bearer particularly designed (as by being provided with corner fittings) for cooperating with hoist equipment for loading onto or unloading from a freight carrier.

53	Stowed as a bridge between trucks:
	This subclass is indented under subclass 52.  Structure or arrangement in which the load bearer is mounted at each end onto separate spaced apart freight carrier running gear structures to constitute the sole connection between them. SEE OR SEARCH THIS CLASS, SUBCLASS: 45, for a particular article so massive as to be accommodated as a bridge between trucks. SEE OR SEARCH CLASS: 105,  Railway Rolling Stock,   subclasses 270+ for a tank pivoted between railway trucks in order to orient its outlet for pouring.

54	Diverse load accommodation, e.g., convertible between semitrailer and container accommodation:
	This subclass is indented under subclass 52.  Structure in which the freight carrier is particularly designed simultaneously or alternatively to accommodate load units of diverse construction, e.g., container and/or pallet and/or semitrailer, and, therefore, necessitating mutually distinct stowage structures or arrangements to be present on or be assembled to or arranged on the freight carrier. (1) Note. These subclasses (54+) require a positive structural detail of each of the accommodations; the plurality of accommodating means or, at least, structure particularly provided to cooperate with each of them. Mere retractability for getting accommodation means of a one type out of the way, and going no further than to prepare the freight carrier for an alternative accommodation is inadequate for this subclass. (2) Note. The original document to structure designed to accommodate a particular article, as defined in subclass 2, and also, alternatively or additionally, a load bearer defined in principal subclass 52 will be classified in the superior subclasses 2+ and should be crossed in this instant subclass (54).

55	Retainer including load lashing anchor capability:
	This subclass is indented under subclass 54.  Structure appropriate for retentive engagement with a load bearer is combined with (e.g., has attached thereto) or is convertible to structure for the attachment device used in load lashing. (1) Note. See subclass 101 for the definition of a load lashing anchor, and search indented subclass 102 for other diverse use devices including an anchor.

56	Semitrailer accommodation:
	This subclass is indented under subclass 52.  Structure in which the accommodated load bearer is of the type provided with running gear at a location limited to the rear portion thereof. (1) Note. An arrangement of wheels at the front end to facilitate stowage (e.g., guidance) on the carrier will bar placement in this subclass, even though the wheels are nonroadable and have no other use than said storage facilitation [See (1) Note in subclass 66]. Mere lowering of the semitrailer landing gear does not, however, constitute stowage (e.g., guidance) facilitation to make said bar to placement herein operative. SEE OR SEARCH THIS CLASS, SUBCLASS: 1, for the inclusion of a turntable mounted on a semitrailer-accommodating freight carrier for stowing the trailer on board the carrier. 53, for a semitrailer stowed as a bridge between railway trucks; in fact, constituting the sole structure linking the spaced trucks. SEE OR SEARCH CLASS: 280,  Land Vehicles,   subclasses 414.1+ for a boat carrying, articulated vehicle, e.g., semitrailer.

57	Fore-and-aft accommodation:
	This subclass is indented under subclass 56.  Structure including accommodating means engaging forward and rear sections of the stowed semitrailer. SEE OR SEARCH THIS CLASS, SUBCLASS: 58+, for a stand collapsibly mounted on a freight carrier for accommodating a semitrailer at its front end. 64, for details of the kingpin retaining latch of such a stand.

58	Collapsible and erectable stand:
	This subclass is indented under subclass 56.  Structure including a support to maintain the fore end of a stowed semitrailer raised above the freight carrier bed and means so linking the support to the freight carrier bed as to be extensible to a raised, supporting position and foldable to a lowered position on or below the bed. SEE OR SEARCH THIS CLASS, SUBCLASS: 57, for semitrailer stowage structure including the fore-end stand and means accommodating the rear end of the semitrailer.

59	Tractor operated:
	This subclass is indented under subclass 58.  Structure wherein the supporting stand is provided with means engageable with a loading or unloading tractor so as to utilize the tractor force for the extensible raising or the collapsed lowering operation.

60	Cushioned:
	This subclass is indented under subclass 59.  Structure including recoverable means, other than merely a resilient block, which is yieldable under the influence of an excessive or inadvertent force whereby to interveningly receive and thereby ward off the undesirable effect of the force upon the stand or the stowed trailer; which means tends to be restored to its prior state upon, and as a consequence of, the cessation of that force.

61	Jack screw erected:
	This subclass is indented under subclass 58.  Structure in which the mounting means for the fore-end stand includes threaded means operable to obtain a force multiplying advantage effective to facilitate raising of the stand and with it, presumably, the mass of the supported fraction of the load.

62	(Fore-and-aft direction slide cushioning means)*:
	This subclass is indented under subclass 58.  Structure wherein the mounting means for the trailer support includes a base portion installed along the carrier floor for movement parallel to the longitudinal axis of the carrier under the influence of (fore-and-aft direction slide cushioning means)*.

63	Cushioned cylinder strut:
	This subclass is indented under subclass 58.  Structure wherein the mounting means for the trailer support comprises underlying leg means including a leg consisting of hollow interfitting parts which enclose means which render than yieldable for telescopic movement in response to inadvertent force incident to freight transportation and recoverable to the earlier state upon and as a consequence of cessation of the force.

64	King pin latch:
	This subclass is indented under subclass 58.  Structure in which the trailer fore-end support includes means particularly designed for releasable retentive connection with a post extending downward from the underside of the fore end of the trailer, which post is analogously employed to join the trailer to the tractor during road use.

65	Accommodation means conforms to wheel sidewall during guidance or rest condition, e.g., rub rail or wheel well:
	This subclass is indented under subclass 56.  Structure in which the freight carrier support surface is provided with accommodation means of such configuration as to be in engagement with a sidewall of the semitrailer wheel during its movement along the freight carrier to a stowed location or when it is at that location, whereby lateral movement of the semitrailer is thereby prevented. (1) Note. The mere lowering of the wheeled landing gear on a deck surface is not considered to convert a semitrailer to a four-wheeled vehicle to bar placement in this subclass in favor of lower subclasses 66+. However, additional (e.g., fore-end) wheels to facilitate guidance for stowage on the freight carrier, even though such additional wheels are nonroadable and have only that stowage facilitation use and capability, is subject matter for that inferior subclass and will be found therein rather than in the instant subclass. See (1) Note in principal subclass 56. SEE OR SEARCH THIS CLASS, SUBCLASS: 57, for a freight carrier provided with rub rail or sunken area structure accommodating the rear wheels of a stowed semitrailer and also with means accommodating the fore end of the semitrailer. 67, for rub rail or sunken area structure accommodating a four-wheeled load bearer.

66	Wheeled load bearer accommodation:
	This subclass is indented under subclass 52.  Structure particularly designed to accommodate such a load bearer as includes rolling support means. (1) Note. The "rolling support means" commonly but not necessarily constitutes the running gear for road use; see indented subclass 67 however, wherein are to be found four-wheel vehicles having roller support structure having utility for facilitating stowage, but impractical for road use. SEE OR SEARCH THIS CLASS, SUBCLASS: 1, for a freight-carrier-mounted turntable for stowing a wheeled vehicle, typically a semitrailer, on board; and wherein wheel guide structure (e.g., track) is mounted on the turntable and wherein, moreover, mating guide (track) structure may further be mounted on the freight carrier.

67	Including wheel guide:
	This subclass is indented under subclass 66.  Structure in which the freight carrier floor structure is provided with means contacting the rolling support members for guiding or for accommodating the supported load unit to or at its stowed position. SEE OR SEARCH THIS CLASS, SUBCLASS: 57, for a freight carrier provided with such structure and also with structure accommodating the fore end of the stowed semitrailer. 65, for wheel guides of the rub rail type for accommodating a semitrailer.

68	Accommodation of rigid wall container for bulk material:
	This subclass is indented under subclass 52.  Structure particularly designed to accommodate such an enclosure as (a) is form sustaining, and (b) contains fluent, particulate, or aggregate material. SEE OR SEARCH CLASS: 105,  Railway Rolling Stock,   subclass 270 for a container for fluids pivoted on its axis between railway trucks so as to reorient the outlet for pouring; and subclasses 358+ for tank cars.

69	Load bearer tripped retainer*:
	This subclass is indented under subclass 52.  Structure including a retainer for the load bearer including a part so mounted and so positioned on the freight carrier as to be moved as a result of contact with a load bearer which is being stowed on the freight carrier. (1) Note. The contact-induced movement may be of the reset type; i.e., undergoing displacement to permit the load carrier to move therepast to be finally positioned, provided that the displacement is followed by spring, gravity, etc., induced resetting for ultimate retentive engagement.

70	Retainer* mounted on (corner pedestal)*
	This subclass is indented under subclass 69.  Retainer* mounted on (corner pedestal)*: Structure in which a load bearer retainer* is installed to extend and move through a wall of a (corner pedestal)* so as to be load tripped upon the load bearer corner(s) mating therewith.

71	Corner pedestal:
	This subclass is indented under subclass 52.  Structure including a horizontal member engaging the meeting edges of a corner of a load bearer and vertical members upstanding from the outer edges of the horizontal member in position to engage corresponding vertical surfaces of said load bearer meeting edges to inhibit horizontal displacement of the load bearer on the freight carrier in the direction both longitudinally and transversely of the freight carrier; the accommodating structure being positioned to maintain the load bearer somewhat raised from the freight carrier surface. (1) Note. The presence of the horizontal member merely upon the upper surface of the freight carrier floor is adequate to satisfy the "somewhat raised" requirement of this instant subclass definition. (2) Note. The disclosure is commonly directed, of course, to a set of four corner pedestals for the respective four corners of the load bearer.

72	Vertically displaceable, e.g., on horizontal axis:
	This subclass is indented under subclass 71.  Structure including mounting means which permits displacement of the corner pedestal between an upper position to maintain the load bearer somewhat raised and a lower, generally nonuse, position of the pedestal.

73	Including male-female retainer*:
	This subclass is indented under subclass 72.  Structure in which the corner pedestal is provided with, or is constructed to mount a retainer*, which is effective within the confines of the vertical and horizontal pedestal members, to penetrate a load bearer corner aperture.

74	Mounted on pedestal which is also slidable along track:
	This subclass is indented under subclass 73.  Structure in which the corner pedestal which is provided with or which mounts the retainer* is itself mounted on guide means for movement toward or away from the location the corner of a stowed load bearer is intended to occupy.

75	And slidable along track:
	This subclass is indented under subclass 72.  Structure in which the freight carrier is provided with guide means constraining the corner pedestal for movement there along-toward and away from an intended location relative to the corner of a stowed load bearer.

76	Including male-female retainer*:
	This subclass is indented under subclass 71.  Structure in which the corner pedestal is provided with, or is constructed to mount a retainer*, effective within the confines of the horizontal and vertical pedestal members, to penetrate within a load bearer corner recess.

77	Retainer:
	This subclass is indented under subclass 52.  Structure in which the accommodating means is attached to the freight carrier and engages a part of the stowed load bearer adequately to effect securement thereto; i.e., to inhibit displacement of the load carrier on the freight carrier in both the lateral and vertical direction. (1) Note. Inhibition of displacement in the lateral direction is presumed when means inhibiting displacement in the vertical direction is brought into play. However, merely inhibiting displacement in the lateral direction will not be assumed to constitute, in itself, retainer structure as herein defined but will be recognized only as generic accommodating means. Rigid material hold-down structure of the hold-down type is predominantly the expedient by which to inhibit vertical displacement of a load--and, typically, lateral displacement as well (note, however, the load bearer (load lashing retainer)* in subclass 85). The basics of a hold-down is paraphrased from the definition of Class 248, Supports, subclass 501, as follows: --form-sustaining structure having an undersurface portion for engaging an upwardly facing portion of a article to retain the article on a support surface--; to wit, in the instant context, a load bearer on a freight carrier surface. SEE OR SEARCH THIS CLASS, SUBCLASS: 57, for the accommodation of a semitrailer on a freight carrier by means cooperating with fore and with aft sections of the semitrailer, which means may be retainer*. 64, for the retention of a semitrailer on a freight carrier by latch means on a stand retentively engaging the king pin at the fore end of the semitrailer supported on the stand.

78	Multiunit retainer:
	This subclass is indented under subclass 77.  Structure in which (a) the retainer includes parts particularly interrelated for retaining a corresponding plurality of stowed load bearers, or (b) there is further provided a common operator to associate or disassociate a plurality of retainers with respect to a corresponding plurality of load bearer units. (1) Note. Consonant with the scope thereof, the above definition does not comprehend the customary plurality of retainers which, in fact, act independently of one another in their engagement with load bearers. Nor does this subclass include the plurality of retainers; however, interrelated in operation, for cooperating in retentively engaging different parts of but a single load unit.

79	Oppositely directed latch pair to retain contiguous load bearers:
	This subclass is indented under subclass 78.  Structure in which the retainer is provided with lateral projections extending in opposite directions and parallel to the surface on which the load bearers are supported so as to be in retentive engagement with a respective pair of side-by-side load bearers.

80	Load bearer understructure retention, e.g., leg engaging:
	This subclass is indented under subclass 77.  Structure including a part mounted on the freight carrier and retentively engaging such a load bearer part as is positioned or projects below the load-support surface thereof.

81	By insertion of completely separable retainer, e.g., bolt, through aligned aperture:
	This subclass is indented under subclass 80.  Structure wherein the retention is effected by the passage of a hitherto independent elongated fastener through coaxial apertures through each of the freight carrier and load bearer parts. (1) Note. The fastener was "hitherto independent" when carried upon the person for use as a retainer. It is also considered "hitherto independent" when hung from a chain or the like at a convenient spot on the load bearer or freight carrier surface.

82	Twist lock:
	This subclass is indented under subclass 77.  Structure comprising a flanged shift the flange of which enters a load bearer fitting past a restriction which partially blocks egress, the shaft being then rotatable about its axis whereby to turn the flange behind the ingress-blocking restriction whereby to lock and retain the load bearer on the freight carrier. SEE OR SEARCH CLASS: 24,  Buckles, Buttons, Clasps, etc.,   subclass 287 for a twist lock joining adjacent load bearers; frequently when on a freight carrier. 294,  Handling: Hand and Hoist-Line Implements,   subclass 81 for a handling device equipped with twist lock terminals to enter the corner fittings of a load bearer for the handling thereof, i.e., to load a load bearer on, or unload one from a freight carrier.

83	Project-retract mounting:
	This subclass is indented under subclass 82.  Structure including means which is on, or parallel to the support surface of the load bearer on the freight carrier, which means mounts the retainer for displacement between (a) an operative position for entry into a load bearer fitting, and (b) a nonuse position locating the retainer flange below the level of that support surface. (1) Note. The load bearer support surface could be the floor or a bolster of the freight carrier or could be a floor- or bolster-attached housing for the twist lock flanged member.

84	Load bearer mounts active retainer received by static freight carrier keeper:
	This subclass is indented under subclass 77.  Structure in which the freight carrier includes a fixed member and the load bearer is equipped with retainer structure including a part movable into retentive engagement with said carrier fixed member.

	This subclass is indented under subclass 77.  Structure comprising means so retaining the load bearer or so related to the load bearer support or retaining structure as to impart thereto recoverable movability so as to be movably yieldable under an excessive or undesirable force and thereby ward off the undesirable effect of that force. (1) Note. The mere compression of a solid block is not herein provided for.

87	Cushioned accommodation:
	This subclass is indented under subclass 52.  Structure comprising means so participating in the accommodation of the load bearer as to impart to the load bearer recoverable movability so as to be yieldable under an excessive or inadvertent force and thereby ward off the undesirable effect of that force upon the load unit.

	This subclass is indented under subclass 108.  Structure in which a row of (tie pieces)* or anchor formations is arranged along, or adjacent and parallel to, the uppermost edge of the vertical body member of the freight carrier and thereby in an exposed and bordering array because the freight carrier has no top wall structure to thwart access thereto.

111	Project-retract (tie piece)*:
	This subclass is indented under subclass 101.  Subject matter in which the (tie piece)* is mounted so as to be recessed within the bounds of the mounting structure in the nonuse position thereof and be shiftable to extend therebeyond and be maintained in that position under the force applied to the attached flexible, lading engaging member.

SEE OR SEARCH THIS CLASS, SUBCLASS: 107, for such a project-retract tie piece on a bordering surface of a freight carrier open to the ambient. 111, for a project-retract tie piece which is recessed in freight carrier facing in its nonuse position.

(1) Note. The "elongated member means" herein defined may be, in fact, part of wider panel structure (e.g., edge, flange; see subclass 108) only when it is unmistakably distinct from the rest of the panel and so narrow as hardly to permit more than a single anchoring to occur at a single location along the row (two would be rare and could occur only under the limitations of subclass 102).

(1) Note. The requirement for either facile securement or disengagement is met where either is disclosed and it is obvious that a reverse manipulation will complete both. Facility in assembling and removal is presumably negated by the necessity to use a tool: but not necessarily. Delivering a light blow to unwedge the device, for example, need not necessarily negate operational facility. (2) Note. Performance of facile assembly and removal may occur for the tie piece and anchor mounting as a unit; or by association and disassociation of the tie piece alone from the means which mounts it on the anchor receiver and remains with it.

The rigid member means in this and the indented subclasses is referred to in disclosures classified hereunder as a bracing member, at other times as a bulkhead. In either case the member is assumed to be effective for bracing a load unit, in any event, to be so similarly shaped and installed as to be classified together regardless of how referred to and, by implication, used. Some few such panel or frame members are herein classified even when not positioned wall-to-wall recognizing, for example, that dimensions appropriately "wall-to-wall" in a freight car do not aptly apply to the hold of a ship, where the panel member may be installed post to post.
