BRACKET FOR SHOW-CASES OR THE LIKE.

SPECIFICATION forming part of Letters Patent No. 782,069, dated February 7, 1905. Application filed April 20, 1903. Serial No. 153,502.

To all whom it may concern.-

Be it known that I, VICTOR SJosTRoM, a citizen ofthe Kingdom of Sweden, residing in Los Angeles city, in the county of Los Angeles, and in the State of California, have invented anew and useful Bracket for Show-Cases or the Like, of which the following is a full,clear, and exact description or specification, reference being had to the annexed drawings and to the letters marked thereon.

This invention, which relates to new or improved brackets for show-cases and the like, has for its object geneally the production of a bracket for supporting the shelves of show-cases (usually formed each. of a sheet or strip of plate-glass sufliciently thick to carry the weight of the articles placed or shown thereon) in such manner that the said brackets shall be removable from the vertical bars .or rods upon which the said brackets are carried and that the said brackets shall also be capable of being slid downward or upward over or upon the said vertical carrying rods or bars and incapable of being removed therefrom without being moved thereof longitudinally or more or less horizontally forward when the gripping or tightening con nection of the brackets With the vertical carrying-bars is sufliciently released after described.

My present invention consists of a bracket capable of carrying or supporting horizontally a shelf in a show-case-such, for example, as a plate of glass, onyx, or other stone, wood, obonite, or vulcanite, or other such sufficiently hard and rigid materialand also capable of being set at several angles with the horizontal and adapted for carrying such shelves or plates at various angles dipping downward. The attachment whereby each bracket is connected to the vertical bars of the show-case or the like is capable of being placed over or upon and removed from the said vertical bars by pushing or pulling the attachment horizontally upon or from the vertical slide-bars and by adjusting and fixing the said bracket thereon by a pinching or set nut and screw, in the manner hereinafter described.

Upon the annexed drawings, Figure l is a as hereinside elevation of a bracket and vertical slidear, to which said bracket is attached, constructed after the manner of or according to the present invention, the bracket in this case being a bracket arranged to be dipped downward at any required angle, as hereinafter described. Fig. 2 is a plan looking vertically downward upon the bracket and slide or carrying bar corresponding to Fig. 1. Fig. 3 is a side elevation corresponding to Fig. 1, with the pinching-nut and pinchingplate shown in Figs. 1 and 2 removed, but also showing the notched quadrantal inner end of the back of the bracket and the inclined slot and guide-pin, by means of the conjoint operation of which when the pinching-nut is released the horizontal position of the bracket is capable of being depressed into one of several inclined positions, of which one such inclined position is shown in dotted lines in Fig. 4. Fig. 5 is a front elevation corresponding to Figs. 1 to 4. Figs. 6 and 7 respectively represent in side elevation and plan the volute spring for opening the gripping-jaws of the device, so as to admit of its removal from the vertical bar of the show-case or other apparatus or system wherein it is used.

The bracket-arm is marked A. This arm A consists of a thin piece of metal thin enough to be flexible and of light weight, as shown in the drawings, and having an m erturned lip l5 at its upper edge. The vertical bracket-car rying bars are marked C, and they are by preference T-shaped in horizontal section, as more particularly seen at Figs. 2 and 5. As shown, a pair of jaws l) and I), I'GSPGCiJlVBly, operate in conjunction with the vertical bar (J. By tightening nut E upon clamping-bolt F, which bolt passes through the jaws D l) and the rear end of bracket-arm A, interposed between them, the jaws are caused to firmly grip the bar C, and thereby hold the bracket-arm A in a horizontal position, and by loosening nut E the arm A may be moved in the direction of the inclined slot (nr upon the pin H, so that any one of the notches a (1/ a" 0/ formed on the inner curved end of the arm A maybe shifted out of engagement with the pin or bolt F and be reengaged with the nut E is released the tension of the volute spring (Z presses the adjacent parts asunder, while the spring itself becomes compressed when the said parts are pressed together by the tightening action of the nut E.

Although I have upon the annexed drawings shown the carrying-bars C C as of T shape in transverse section of the bars, yet it 18 to be understood that these bars may be any other which provides the requisite stiffness of the bar. For example, the transverse section may be triangular, or curved, or corrugated, or of other transverse section when the metal constituting the said bars is thick enough and broad enough to produce the requisite stiffness, and the parts of the jaws D and l) which engage with the bars C C are always formed or shaped to correspond with the shape i l l l l l l l l of the edges of the bars with which they engage. For the purpose of rendering the jaws D and D stiff when formed of thin material they maybe corrugated.

Having now described the nature of my said invention and the best system, mode, or manner I am at present acquainted with for putting the same into practical effect, I desire to observe in conclusion that what I. consider to be novel and original, and therefore claim as the invention to be secured to me by Letters Patent, is as follows:

A shelf-bracket comprising an arm having a series of notches and an inclined slot in its rear end, said arm consisting of a plate of thin metal, clamping-jaws embracing the rear end of the arm, a pin pivoting the arm through said inclined slot to the jaws, and a clampingbolt for the jaws, said bolt being adapted to engage either of said notches in the arm, substantially as described.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
