Specification of Letters Patent. Application filed October 19, 1905. Serial No. 288,494,

Patented Nov. 13. 1996.

To all whom it may concern.-

Be it known that I, EDWARD MELCHIOR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Adjustable Shelf-Supp orting Brackets, of which the following is a specification.

My invention relates to adjustable shelfsupporting brackets; and one of its objects is to provide a bracket of this character wherein the hooked keys or members for securing the bracket to the supporting-bar are fixedly related and arranged or projected in reverse directions-that is, the upper key projects upwardly and the lower key downwardly-and wherein the lower key is shorter than the upper. key and provided with a downwardlyinclined inner face, thus permitting the application of the bracket to the supportingbar by inserting the upper or larger key in one of the ke -receiving openings of the supporting-bar, fiy inserting the lower or smaller key in the next adjacent lower key-receiving opening, and by then moving the bracket downward, this downward movement of the bracket serving to direct the lower key behind the opening through which it projects and by virtue of its inclined face firmly locks the bracket in applied position.

Another object of the invention is to provide a bracket of this character wherein the top or shelf-receiving plate has its rear end provided with flanges serving to engage the supporting-bar to prevent the bracket from having any sidewise movement thereon.

A still further object of the invention is to provide the web of the bracket with lugs for engagement with the supporting-bar, to also prevent the bracket from having sidewise movement thereon, it being understood that the bracket may be provided with both the flanges and lugs, or with either of them.

With the above and other objects in view the invention consists in the construction,-

combination, and arrangement of parts hereinafter fully described, claimed, and illustrated in the accompanying drawings, where- Figure 1 is a view in side elevation, illustrating my improved bracket in applied position. Fig. 2 is a vertical central sectional view thereof, and Fig. 3 is a detail perspective view of the rear end of the bracket.

Referring to the drawings by reference characters, A designates the supporting-bar,

and B the bracket, said supporting-bar being channeled to provide flanges 1 and a connecting-flange 2. The flanges 1 serve to space the connecting-flange-2 from the support to which the bar is secured, while the connecting-flange 2 is provided-with a plurality of key-receiving openings 3.

The bracket B comprises, in the main, a web 4 and atop plate 5, the top plate 5 bein secured to the web 4 in any manner found desirable. The web 4 has its rear end formed with hooked keys or supporting-bar-engaging members 6 and 7, said keys being fixedly related and arranged or projected in reverse I the upper key 6 projects upwardly and-the lower key 7 downwardly. The key 6 is of a length greater than that of the key 7, while the key 7 is rovided with an inner downwardly-inclined ace 8. The formation of the keys 6 and 7 rovides the rear end of the web 4 with shoul ers 9, said shoulders resting upon the lower walls of the keyreceiving openings 3 when the bracket is in applied position.

The bracket is secured in appliedposition by first inserting the key 6 in one of the keyreceiving openings 3, by then tilting the bracket and directing the key 7 in the next adjacent lower opening 3, andby then moving the bracket downward. This downward movement of the bracket serves to direct the key 7 in rear of the connecting-flange 2, and in view of the inclined face 8 of said key the bracket is caused to firmliyl bind against the connecting-flange 2, and t us firmly lock the bracket in applied position upon the supporting-bar. The shoulders 9 of the web 4 rest upon the lower walls of the key-receiving openings 3, and thereby limit the downward movement of the bracket.

The rear end of the top plate 5 is cut away, as at 10, to provide flanges 11. The flanges are arranged upon each side of the web 4 and are bent downwardly and rearwardly to provide supporting-bar-engaging members 12, which engage the front face of the connecting-flange 2 and prevent the bracket from having any sidewise movement upon the supporting-bar. The rear end of the web 4 is provided at points intermediate the keys 6 and 7 with laterally-disposed supporting-barengaging members 13, which also prevent the bracket from having any sidewise movement upon the supporting-bar A.

The bracket may be provided with the members 12 and 13, or it may only be provided with the members 12-, the use of the directions-that is,

members 13 being optional, as the members 12 will serve the purpose of preventing any sidewisc movement of the bracket upon the supporting-bar.

It is apparent from the above description, taken in connection with the accompanying drawings, that I provide a novel and highlyuseful adjustable shelf-supporting bracket which may be firmly and rigidly secured in a plied position, which is simple and durable oFconstIuct-ion, and which maybe manufactured and sold at a com aratively low cost.

From the foregoing description, taken in connection with the accompanying drawings, the construction and mode of operation of the invention will be understood without a further extended description.

Changes in the form, proportions, and minor details of construction may be made within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

Having fully described and illustrated my invention, what I claim i's 1. In a device of the character described, the combination with a supporting bar provided with key-receiving openings, of a bracket comprising a web and top plate, said web being provided with hooked keys and supporting-bar-engaging members arranged between the keys, and said top plate being also provided with supporting barengaging members.

2. In a device of the character described, the combination with a supporting-bar provided with a key-receiving opening, of a bracket comprising a web and top plate and provided with a key, said plate having its rear end bent downwardly and rearwardly to provide a supporting-bar-engaging member.

3. In a device of the the combination with a supporting-bar provided with a key-receiving opening, of a bracket comprising a web and top plate and provided with a key, said top plate having its rear end cut away and bent downwardly and rearwardly to provide supporting-barengaging members.

4. In'a device of the character described, the combination with a supporting-bar provided, with key-receiving openings, of a character described,

bracket provided with fixedly related hooked keys, one of said keys projecting upwardly, while the other-of said keys projects downwardly, the construction and arrangement of the openings and keys being such that upon tilting the bracket the upper key may be inserted through one of the openings in rear of the supporting-bar to permit the in sertion of the lower key through another opening, whereby upon a downward movement of the bracket both keys will lock the bracket to the supporting-bar.

5. In a device of the character described, the combination with a supporting-bar provided with keyreceiving openings, of a bracket provided with fixedly related hooked keys, one of said keys projecting upwardly, while the other of said keys is smaller and projects downwardly, the construction and arrangement of the openings and keys being such that upon tilting the bracket the larger key may be inserted through one of the openings in the rear of the supporting-bar to permit the lower key to be inserted through another of said openings, whereby upon a downward movement of the bracket the keys will lock the bracket to the supporting-bar.

6. In a device of the character described,

the combination with a supporting-bar provided with keyreceiving openings, of a bracket provided with fixedly related hooked keys, one of said keys projecting upwardly and being longer than the width of the ke receiving openings, while the other of said keys projects downwardly and is shorter than the Width of said openings, the construction and arrangement of the openings and keys being such that upon tilting the bracket the larger key may be inserted through one of the openings in rear of the supporting-bar to permit the smaller key to be inserted through another of said openings,

whereby upon a downward movement of the bracket the keys will lock the bracket to the supporting-bar.

In testimony whereof I afiix my signature in presence of two witnesses.

EDWARD MELcHIoR.
