Aug. 25, 1931. J. H. Boss WINDOW SHADE BRACKET Filed May 5, 1951 Patented Aug. 25, 1931 UNITED STATES PATENT OFFICE JOHN H. BOSS, OF BALTIMORE, MAIR/YIM'LNI), ASSIGNOR OF ONE-HALF TO JOSEPH STABELE, OF BALTIMORE, MARYLAND WINDOW SHADE BRACKET Application filed May 5, 1931. 'Seri aiNo. 535,114.

This invention relates to a shade roller support or bracket and has special reference to a combined shade roller and curtain rod fixture.

One important object of the invention is to improve the general construction of devices of this character.

A second important object of the invention is to provide a novel form of such iix Sure wherein there is a bracket slidable along the body or base of the fixture so as to accommodate variations in the length of the shade roller.

A third important object of the invention is to provide a device of this character wherein the principal parts can be made economically from sheet metal.

With the above and other objects in view, as will be hereafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.

In the accompanying drawings like characters of reference indicate like parts in the several views, and

Figure 1 is a front elevation of the invention.

Figure 2 is a section on the line 22 of Figure 1.

Figure 3 is a section on the line 3-3 of Figure l.

Figure 4 is a perspective view of the shade roller bracket used herewith.

Figure 5 is a perspective View of a presser or looking plate used herewith.

Figure 6 is a perspective View of a locking cam used herewith.

In the embodiment of the invention shown in the drawings there is provided a rectangular base plate 10 having its edges bent back to form a peripheral flange 11. Ad-

7 jacent each corner this plate is provided with a screw receiving opening '12 by which screws may be used to secure the device to a window frame. This base is preferably made of sheet metal and U-sliaped slits 13 are formed adjacent the top and bottom edges of the base. The metal defined by these slits is struck out forwardly of the remainder of the body to provide broad but low tongues 14 extending toward'each other in parallel relation. 7

In connection with this base there is provided a bracket having a rectangular bracket base 15"arranged with its ends beneath the tongues 14. Projecting from one side of this plate and extending forwardly from between the tongues 14 is a flange 16 having a suitable slot or opening 17 to receive the pintle of a shade roller. Similarly a flange 18 extends forwardly from the other side edge of the base 15 and these twoflanges are provided with alined bearing openings 19.

the outer or front faces of the tongues and is provided with a slot 21 through which the flange 18 projects. It will be noted from Figure 5 that the middle portion of the pressor plate is offset from the ends and, as shown in Figure 1, the major portion of this plate lies between the flanges 16-and 18 of the bracket.

-A cam member is provided to force the presser plate toward the base 15 and thus to clamp the tongues 14 between these parts and thereby hold the-bracket in' adjusted position on the base 10. This cam member is in the form ofa strip of metal bent to form a substantially. L-shaped lever having a short presser-arm 22 and a long operating arm 28. At the junction of these arms the lever is provided with laterally extending journal lugs which engage in the bearing openings 19 and thus pivotally mount the cam member, being'carried by said flanges. When moved into the position shown in Figure'3 the cam member causes the bracket to be securely clamped against A presser plate 20 rests at its ends on movement along the base 10 but, when the v iii the base 10 so that the end of a tubular curtain rod may be fitted securely thereon and obviously it is intended that these fixtures be used in pairs as is common in all such fixtures.

It is obvious that minor changes may be made in the form and construction of the invention without departing from the material principles thereof. It is not therefore desired to confine the invention to the exact form herein shown and described, but "it is desired to include all such as properly come within the scope claimed.

\Vhat is claimed as new, is;

l. A shade roller fixture including a base, a pair of opposed transversely extending tongues carried by said base and spaced forwardly therefrom, a bracket member having a base provided with ends extending behind said tongues and having side flanges projecting forwardl from between said tongues, one of said i anges having means to receive the pintle of a shade roller, said flanges having alined bearing openings, a presser plate between said flanges and having its end resting on said tongues, and a cam member provided with an operating arm pivotally mounted on said flanges and between the same, said cam member being arranged to force the presser plate toward the base of the bracket and thereby clamp said tongues.

2. A shade roller fixture including a base, a pair of opposed transversely extending tongues carried by said base and spaced forwardly therefrom, a bracket member having a base provided with ends extending behind said tongues and having side flanges projecting forwardly from between said tongues, one of said flanges having means to receive the pintle of a shade roller, said flanges having alined bearing openings, a presser plate between said flanges and having its end resting on said tongues, said presser plate extending at one side beyond the bracket and being slotted to receive the flange at said side, and a cam member provided with an operating arm pivotally mounted on said flanges and between the same, said cam member being arranged to.

force the presser plate toward the base of the bracket and thereby clamp said tongues. In testimony whereof I aflix my signature.

JOHN H. BOSS.
