This invention relates to an adjustable display shelf, and the primary object of the invention is to provide a shelf that maybe readily adjusted to the desired length and fastened on a cash register, anarticle of furniture, a box, a wall jutting, or any other place where it is practical to fasten a clamp.

A further object is to provide an adjust able shelf of the above kind which is simple and durable in construction and efficient in use. I

Other objects will appear as the nature of the, invention is better understood and the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings, and claimed.

In the drawings:

Figure 1 is a to plan view of a display shelf embodying t 1e present invention, applied to a wall jutting.

Figure 2 is ,an enlarged transverse section on line 22 of Figure 1. v

Figure 3 is an enlarged fragmentary section on line 33 of Figure 1.

Figure t is a perspective view of one section of a modified form of shelf embodying ing member for the shelf carried by said section.

The present displayshelf is designed to attractively display articles of merchandise at places where ordinary shelves cannot be utilized. In other words, ordinary shelves involve supporting brackets or pedestals which occupy considerable space and often make it impossible to conveniently arrange the shelves, while thepresent invention is 7 devoid of supporting brackets or pedestals which require considerable space and can be readily clamped to any suitable support.

Referring in detail to the drawings, the present shelf consists of two

telescopingsections

5 and 6, preferably formed of sheet metal, and respectively having rearwardly projecting clamp arms 7 and 8 rigidly attached to the outer ends thereof. By sliding the

sections

5 and 6 relative to each other, the

shelf may be adjusted as to length to roughso ly correspond to the width of the wall jutting or other support 9 to which the shelf is to be attached, and such adjustment is maintained by suitable means, such as a headed pin 10 adapted to engage in registered ones 59 of longitudinal series of openings 11 and 12, respectively provided in the

sections

5 and 6. One clamp arm has a fixed jaw 13 at the inner side of its free rear end adapted to engage one side of the support 9, while the other clamp arm has a laterally adjustable jaw 14 adapted to be adjusted against the other side of the support 9 and to cooperate with the jaw 13 to firmly fasten the shelf in place, either horizontally or slightlytilted, 7

as desired. As shown, the jaw 14 is swivelled on the inner end of an adjusting screw 15 threaded transversely through the free rear end of the clamp arm.

Theshelf

sections

5 and 6 are formed of 7, longitudinally return-bent sheets of metal so as to be of flattened form in cross section and to present wide platform portions having flange portions 16 rising from the front edges thereof to prevent articles from falling forwardly off of the shelf and to stiffen the shelf. The sections may be made in this way as shown in Figures 4 and 5, or they may be shaped to further provide forwardly projecting horizontal ledge portions 17 on the up- {:5

per edges of the flange portions 16, as shown in Figures 1 and 2, to enhance the appearance of the shelf and to receive suitable advertising matter. The inner section f. the

shelf has its folds contiguous, while the folds of the outer section 5 are spaced apart to snugly slidably receive said inner section 6. The structure thus produced is very stiff and durable, and for further stiffening purposes the rear longitudinal edge portions'of the upper walls or folds of the

sections

5 and 6 are rolled downwardly to provide beads 18 which telescope one within the other.

The

sections

5 and 6 have wings or extensions 19 on the rear outer end portions thereof received in slots 20 provided in the forward end portions of the clamp arms 7 and 8, and passing through these extensions and the clamp arms are screws 21 or the like by means of which the clamp arms are effectively rigidly attached to the shelf sections. Upturned flanges 22-are provided on the forward outer end portions of the upper walls or folds of the shelf sections to cooperate with the clamp arms in preventing displacement of articles from the shelf at the ends of the latter.

In order to prevent sagging of the shelf intermediate its endswhen an exceptionally long shelf is used or when heavy articles are placed on the shelf, an intermediate sup porting member may be provided, embodyinga flexible angular plate or bracket 23 having a horizontal arm welded or otherwise fastened to the under side of the shelf section 5 at its inner end and a depending arm arranged to bear against the front face of the support 9 as shown in Figures 2 and 6. The clamp arms 7 and 8 and the depending arm of bracket 23 have suitable friction faces 24: to prevent slipping or inarring of the support.

In use, the

sections

5 and 6 are slid relatively to roughly adjust the shelf to a length approximating the width of the support, and

the pin 10 is inserted in registered ones of the openings 11 and 12 to maintain such adjustment, the rear edge of the shelf is then positioned adjacent the front of the support with the jaw 13 of arm 7 engaging one side of the support. The screw 15 is then turned to draw the jaws l3 and 14 tightly against the opposite sides of the support, thereby firmly fastening the shelf in place.

It will thus be seen that we have provided a very simple and durable shelf exceptionally well adapted for the intended purpose and uses. A tier of these shelves having different widths would provide for effective display of small articles, and economy of space under'all conditions of use is insured.

Minor changes are contemplated within the spirit and scope of the invention as claimed. The depending arm of bracket 23 may be bent to the desired angle to properly engage the support, whether the latter be truly vertical or not, or whether the shelf be disposed horizontally or at an inclination.

What we claim as new is:

1. An adjustable shelf comprising inner and outer telescoping sections having rearwardly projecting clamp arms rigidly attached to the outer ends thereof to grip a support therebetween and means to secure said sections in their relatively adjusted positions, one of said clamp arms having a jaw adjustable toward or away from the jaw of the other clamp arm. f

2 An adjustable shelf comprising inner and outer telescoping sections having rearwardly projecting clamp arms rigidly attached to the outer ends thereof to grip a support therebetween and means to secure said sections in their relatively adjusted positions, one of said clamp arms having a jaw adjustable toward or away from the jaw of the other clamp arm, said securing means comprising a pin, said sections having longitudinal series of openings for selective registration and reception of said pin. 7

3. An adjustable shelf comprising inner and outer telescoping sections having rearwardly projecting clamp arms rigidly attached to the outer ends thereof to grip a support therebetween, said sections having extensions on the outer ends thereof, said clamp arms being spaced apart for receiving said extensions therebetween, and means rigidly securing said clamp arms to said extensions. I
