ADJUSTABLE isnaokn'rl i hpplicationfiled May 23, 1912. Serial No. 699,098.-

To all whom it may concern:

Be it known that LGEORGE R. Mnrnnooim,

' a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Adjustable Brackets, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, ref erence being had to the accompanying drawings, which form a part of this specification. 7

My invention has for its object to produce a strong, simple bracket which may readily be adjusted to fit slabs or shelves of various sizes.

The various features of novelty whereby my invent-ion is characterized will hereinafter be pointed out with particularity in the claims; but, for afull understanding of my invention and of its object and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawing, wherein: I

Figure 1 is a central vertical section through a bracket arranged in accordance with a preferred form of my inventiomthe dotted lines showing the adjustable member extended; Fig. 2 is a view looking toward the right in Fig. 1, that is a back view of the bracket; and Fig. 3 is an elevation of the loose clamping piece.

Referring to the drawing, 1 represents a plate, preferably of sheet metal having roughly the outlines of the letter T. Along its edges the plate is bent back to form a continuous flange 2 which gives stiffness to the plate. Near the ends of the cross arm 3 of the plate are holes 4c for receiving screws or other fastening means. At the juncture of the two arms of the plate the metal is pressed back to form a nipple 5 of such length that it will not extend beyond the plane of the back edge of the flange 2.

6 is a metal tube which is forced into the nipple from the front sideo-f the plate and is either held frictionally or is brazed or soldered in place. By pressing back the metal of the plate to form the nipple a com paratively long bearing is obtained for the tube and the latter willftherefore be firmly held when the bracket is fastened to awall and will not yield under a considerable weight imposed thereon. The freeend of Specification of Letters Patent. j

the tube is threaded internally as at"? for the reception of an elongatedstud 8. 1 Loose upon the stud is a small clamping plate 9 which is adapted to cooperate with the member 1 to clamp aslab or shelf upon the bracket. The member 9 may be provided with a laterally extending lip 10 adapted to overlie the slab or shelf so as to prevent the latter from being lifted from the bracket until the'stud is loosened.

It will be seen that the stud may be adjusted lengthwise of the tube or arm 6 so as to adapt the bracketto slabs or shelves of various widths. It is therefore unnecessary to have a different bracket for each width of slab or'shelf, it being suflicient to have a few brackets having tubular arms I without screw-threads, the interior of the tube at the outer end being enlarged to receive this plain portion of the stud. This arrangement will permit the stud to be ad justed within'considerable limits without exposing any of the screw-threads and consequently the bracket will have substantially the same appearance for all adjustments.

While I have illustrated and described only a single preferred form of my invention, I do not desire to be limited to the particular structural details thus illustrated and described; but intend to cover all forms l and arrangements which fall within the terms employed in the definitions of my invention constituting the appended claims.

I claim: j

1. In a bracket, a plate, an arm projecting outwardly from one face of the plate at right angles thereto, a ,member screwthreaded within the end of said arm, and a: clamping piece loose on said member and adapted to T cooperatewith said plate to hold a shelf or the like, on the bracket.

2. In a bracket, .a plate, a. tube secured at one end to the plate and extending at right angles thereto,qan elongated stud screwed into the free'end of the tube, and a clamping. piece loose on the stud and adapted to cooperate with said plate to outer end ofthe tube, and means on the 10 hold a shelf or the like on the bracket.
