SECTION I - CLASS DEFINITION

This class provides for devices which carry the weight of an article or articles or otherwise hold or steady it or them against the pull of gravity, and devices for holding an article to its support, which are not otherwise provided for.

(1) Note. Devices having structural features limiting them to use in a particular art remain with the art.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

LINE BETWEEN CLASS 248, AND CLASS 362, CLASS 313/39, AND CLASS 431

The line between this class and Classes 362, Illumination, 313, Electric Lamp and Discharge Devices, subclass 39, and 431, Combustion is as follows:

Class 223, Apparel Apparatus, subclass 120 for supports, bases and stands claimed in connection with means for making, repairing or maintaining in condition articles of apparel.

Class 362 takes any combination of a support with significant structure of the light distributing means or the combination of the light distributing and generating means.

Class 313, subclasses 49+ is the generic class for the combination of a support with significant structure of an electric space discharge device. See Lines With Other Classes, "Combined with a Support" of the class definition for the other classes which provide for the combination of a support and a discharge device.

The mere supporting structure goes to Class 248 and such supporting structure may include conduits for fuel or energy and mere cut-offs therefor. Supporting structures limited to use with lighting devices are in Class 362. Supports for a light generating device are in Class 248 unless a significant structure of the light generator is claimed, in which case it goes to Class 431 or Class 362.

The mere naming of a light or discharge device as the thing supported will not operate to take the case out of Class 248. If the support is in itself an essential part of the lamp or discharge device such as are many lamp bases, it remains in the art class. In Class 313, class definition, see the following sections of Lines With Other Classes: "Combined with Electrical Connector Structure,...(3) Electrodes Combined with Connector Structure"; and see "Envelopes, Casings, and Jackets for Lamps and Discharge Devices,...(1) With Attached Base" for the classification of an envelope with a base attached thereto.

LINES BETWEEN CLASSES 313, 248, AND 174

See Class 313, Electric Lamp and Discharge Devices, subclasses 49+ for electric space discharge devices in combination with a mere supporting means therefor. See subclasses 238+ which provide for electric lamp and discharge devices which have supporting or spacing structure for the electrodes or shielding members thereof. See Class 248, subclass 50, which provides for supports for elongated discharge or lamp tubes (e.g., neon) where no electrical features are involved. See Class 174, Electricity: Conductors and Insulators, subclass 138 which provides for insulated supports for neon and similar elongated tubular lamps where the support includes no structure limiting the device to use with electric lamps. Also, see paragraph 1 of Lines With Other Classes and Within This Class, above.

LINE BETWEEN CLASS 211 AND CLASS 248

Class 211 is a specific class under the class definition of this class (248). In general, Class 211 is the generic support class for plural articles and Class 248 is the generic support class for single articles. However, Class 248, subclasses 235 - 250, inclusive, subclasses 309.1 -316.7, inclusive, subclasses 500 - 509, inclusive, and subclasses 511 - 541 inclusive, additionally provide for supports of plural devices of the same (i.e., nondiverse) nature, and any of the subclasses in this class (248) will take plural diverse supports where one of the supported devices is ancillary to the main device supported (e.g., check, label and tag holders combined with an article support); while in Class 211 additionally provides for supports for single articles.

This Class 248 provides for the combination of a mirror broadly together with its frame and its support. However, Class 52, Static Structures (e.g., Buildings), provides for a mirror frame, per se, and a mirror broadly claimed with its frame; see especially subclasses 474+ and 633+. Class 40, Card, Picture, or Sign Exhibiting, in subclass 700 provides for picture frames and in subclasses 745+ provides for such frames claimed in detail together with supporting structure. Class 40 also provides for frames whose use is indicated as for both mirrors and picture. Class 40 provides for picture and sign (including license plate) details with or without supporting structure.

(2) Note. As between this Class 248 and Class 359 a mere claiming of a plurality of signal reflectors of the Class 359 subclasses 515+ type does not preclude classification of subject matter otherwise classifiable in Class 248. However, if any physical arrangement or optical relationship between the signal reflectors is recited, classification is in Class 359. A mere plurality of image forming mirrors is classified in Class 359.

[List of Patents for class 248 subclass 511]

511

STAFF TYPE:

This subclass is indented under the class definition. Support comprising a device which includes means particularly adapted to receive a staff (i.e., a pole-like or rod-like member) and to support it in one or more attitudes relative to either (1) the device, (2) the surface or object upon which the device relies for its support, or (3) a principal plan (e.g., horizontal, etc.). The device may (1) be a stand or base, (2) include structure in the form of a ground insertable member, or (3) be a bracket. The staff receiving means usually is a distinct element such as a socket, cradle, ring, etc.; in rare instances, however, it may be an integral portion of the device. Typical examples of a staff are a fishing rod, a flagpole, a tree trunk and an umbrella stick. Included in this subclass (511) are structures involving the rather peculiar arrangement wherein the device supports only part of the weight of the staff; i.e., the staff rests also, at some other point of its length, upon a surface or an object. Included are "stands" comprised of a plurality of individual, leg-like members which have no engagement with one another, and which achieve an operative relationship with one another only at such time as they are attached to an end of a staff for supporting it in an upright position.

(1) Note. The staff receiving means of this and the indented subclasses usually is of a "universal" nature; i.e., it will accommodate one pole-like or rod-like element about as well as another. Accordingly, a staff which includes structure peculiar to a particular art device, and with which structure the staff receiving must cooperate, usually presents a combination or sub-combination which is more properly classifiable with the art device. However, that statement is not intended to proscribe staff modifications where the modification has utility only in its cooperation with the staff receiving means, such as the tapering of the lower end of a tree trunk to better fit the socket of a staff receiving means, or the boring of a hole therein to receive a spike-like member of a staff receiving means, for example.

(2) Note. The existing cross references to other areas of this class of patents which appear as original documents in this and the indented subclasses, have not been screened to determine whether their placement is consistent with the concepts adopted herein of such terms as "stand" and "bracket".

Angularly adjustable:

This subclass is indented under subclass 511. Support wherein the staff receiving means is adjustably connected to the device, whereby the staff is movable in one or more planes with respect to the device. A means (friction brake, lever and detent, etc.) to secure the staff receiving means against movement relative to the device is required. Neither a movement of the staff within its receiving means, nor a repositioning of the device relative to its supporting surface or object, constitute the movement of the receiving means relative to the device that is fundamental to this subclass.

(1) Note. Where more than one centering or retaining means is present, it is not necessary that each means move relative to the device; rather, it is sufficient if one moves, as an entity, relative to the device (and therefore, relative to any other means).

(2) Note. Rotation of the staff receiving means about its longitudinal axis (i.e., the longitudinal axis of the staff) relative to the device is deemed to be for the sake of adjustment (and therefore proper for this subclass ) if a means to secure against rotation is provided.Rotation for its own sake (i.e., in the absence of a securing means) is specifically provided for -- in the instance of a stand or base type device -- in subclasses 521+.

Support wherein the device includes structure whereby it can be supported by, alternatively, plural types of supporting surfaces or object; e.g., the device can be either (1) a stand or a ground inserted device, (2) a stand or a bracket, or (3) a ground inserted device or a bracket.

(1) Note. The claiming of means (e.g., apertures) to receive fasteners in the surface-contacting portions of a device in the nature of a stand, for the purpose of securing the device to the surface, is not an alternatively mountable feature for this subclass in the absence of a disclosure that the device may be used without the fasteners on a generally horizontal surface as a stand and used with the fasteners on a nonhorizontal surface as a bracket.

[List of Patents for class 248 subclass 519]

Support wherein the staff receiving means is a component of a device which is inherently stable when resting, without attachment, upon a generally horizontal surface. The device is the sole support for, and bears the entire weight of, the staff receiving means and staff.

(1) Note. A device designated as a stand or a base but having means for attachment to an underlying surface (e.g., screws), or to an outlying surface (e.g., guy wires), or which is disclosed as requiring some such form of attachment, does not fulfill the stability requirement of this subclass; rather, it is considered to comprise a bracket for subclasses 534+ below.

[List of Patents for class 248 subclass 523]

523

Having staff retaining or centering means:

This subclass is indented under subclass 519. Support wherein the staff receiving means includes means to grip and/or to align the staff therein. This and the indented subclasses involve, predominantly, structure for supporting a Christmas tree.

(1) Note. A cylinder with a closed bottom (i.e., a socket) is not a means for this subclass unless the respective diameters of the cylinder and the staff are so related as to necessarily result in a retaining or centering function; in the absence of such a relationship, the structure is in subclass 519 above. On the other hand, the staff receiving means of this subclass may comprise only an up-standing pin which either is driven into the bottom of the staff or else is received in a complementarily-sized bore formed in the bottom of the staff.

524	Plural means, vertically spaced:
	This subclass is indented under subclass 523. Support wherein the retaining or centering means are at least two in number and are positioned above and below one another. While the means more often than not are diverse in nature, the more significant aspect is that their contact with the staff is at regions of the latter which are spaced vertically from one another. In some instances the plurality of means comprises only a single member, or set of members, which member, or members, have vertically spaced, staff contacting portions. Mere "teeth" formed on a means or element thereof at a single region of contact with the staff are not within the spaced-contact concept of this subclass, nor is continuous contact over a portion of the length of the staff (e.g., as in the instance of a sleeve).

Including pivoted, staff-engaging supporting legs:

This subclass is indented under subclass 524. Support wherein one of the retaining or centering means comprises a plurality of legs which are pivotably attached to the device and support it in elevated relation to the generally horizontal surface. Except in the rare instances where there are more than two retaining or centering means, the pivoted legs constitute the upper one of the means. Pivotable movement of a leg about its axis, which axis usually is horizontal, causes its upper portion to move into or out of engagement with the staff, and tooth-like structure frequently is provided on the staff-contacting area of the upper portion for the purpose of enhancing its grip on the staff.

(1) Note. In view of the pivotable attachment of the legs, the supports of this subclass (525) more often than not are of a foldable nature within the meaning of subclass 528 below.

Engagement is responsive to weight or thrust of staff :

This subclass is indented under subclass 525. Support wherein the exertion of a downward force by the staff (i.e., resulting either from its weight or from an externally-applied force) causes the supporting legs to grip the staff more tightly.

(1) Note. While the structure of this subclass usually do not appear to differ materially from those of the preceding subclass (525) and therefore might function similarly, nevertheless the patents which appear in this subclass (526) are those which claim or otherwise disclose the functional relationship described.

Support wherein one or more of the retaining or centering means comprises a plurality of generally horizontal elements which are in threaded engagement with the device and are axially movable into or out of engagement with the staff. Where there are not more than two retaining or centering means, the screw usually constitutes the upper one of the means.

(1) Note. While a support of the kind found in this subclass usually has the capability of changing the attitude of the staff (e.g., to "plumb" it), it is not an angularly adjustable support within the meaning of subclass 514 above; see the reference therein to this subclass for an explanation of the difference.

RESILIENT SUPPORT:

This subclass is indented under the class definition. Structure comprising a resilient means wherein said means takes at least part of the weight of the supported article and permits relative movement or vibration thereof with respect to a support.

(1) Note. Almost every material possesses some elasticity or resilience. Moreover, many substances such as rubber, cork, etc., which are often used in certain applications because of their resilient properties, are also used in other applications because of other properties which they possess, which are unrelated to their resilient properties. Hence, a structure such as a mere mat, pad, sleeve, bushing, cover, etc., which is used primarily because of its frictional, nonmarring or protective properties, is not placed in this subclass, but is classified in the subclasses below on its physical characteristics even though it may incidentally function to dampen sound or to provide a slight cushioning effect.

(2) Note. This subclass does not include a device wherein a resilient means acts in opposition to gravity but without sufficient force to actually support the article, for example, a counterbalanced support which bottoms, or in which the resilient means is ineffective in the normal operation of the device. Such devices are in the subclasses below. However, this subclass does include a device wherein the resilient article is displaced from a neutral or equilibrium position if the weight of the supported article is taken by the resilient means during such displacement.
