INVENTOR H6 Myedarn .BY 's ATTORNEYjW Patented Jan. 31, 1933 HENRY c. HAGEDORN, or swan-e01; NEW Yogak ADJUSTABLE WINDOw -SHADE SUPPORT Application filed January 15, 1932. serial No. 586,?76.

The main object of this invention is the provision of a novel support for roller shades mounted on windows, for the purpose of permitting adjustable movement of the shade away from the window to permit opening of the window without the accompanying rattling of the shade as is usually caused by the wind which enters an open window.

Another object of the invention is the provision of an adjustable roller shade supporting bracket for windows, whereby the roller of the shade may be swung outward and downward away from the window, for the purposes above-mentioned.

The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing, Figure l is a front interior elevational view of a window equipped with the adjustable suport; p Figure 2 is an enlarged perspective view of the support member, one being used on each 5 side.

ing arm, showing the means for limiting the downward movement of this arm.

Figure 5 is an enlarged perspectiveview of the lower end of the stationary support member.

Referring in detail to the drawing, the numeral 10 represents a window frame of usual construction. On both sides of this frame, near the upper ends thereof, vertical, stationary brackets 11 are mounted by suitable means, such as screws passing through openings 12. Each bracket 11 compr ses side walls 13 joined by a face 14. A ridge 15 extends around the face 14, leaving a groove 16 inside the ridge.

An arm 17, having its upper end 18 ofi'set as shown, is pivotally secured by the lower screw through the opening 12, to the lower end of the bracket 11. A ridge 19 extends around this arm, of the same conformation as the ridge 15, and an arcuate ridge 20 surrounds the opening, l2inthis in order to increase the friction between the members;

The ridges mentioned m an formedb stamping them out of sheet metal,'of whi c the members are form'ed',,so that th bppo. site si'de of the member will have a similarlyshaped groove therein. In the offset, end: 18 of the arm 17, the ends'of the shade roller 21, carrying'the' shade 22, are supported In the lower end of bracket 11,..between the wall 13and ridge 15,355 shown in Figure 5, an arcuate slot is cut oiit, indicatedat 23, the are representing a quadrant ,of a circle. At the pivoted end-ofthe arm 17, similarly between the edge of. the arm and the ridge 19;"a depression is stamped into the arm, shown at 24, causing a tongue or lug 25 to be formed on the opposite side.

Assuming that the shade is in normal position, that is, that the arm 17 and bracket 11 are in vertical, mutually aligned position, these members are retained in this position by the registering of the ridge 15 in the groove formed on the arm 17 by the stampedout ridge 19. As the members are of sheet metal, they are resilient and therefore tend to remain interlocked. At this time the lug 25 lies against the upper end of slot 23. When it is desired to open the window at the top and at the same time to avoid rattling of the shade in the wind, the roller 21 is swung outward and downward from the window, thus disengaging arm 17 from bracket 11 and rotating the former about the lower pivot. Because of the resiliency of both members, the arms 17 will frictionally remain in any position, within its limits, so that the distance of the shade from the window may be varied at will. 7 have reached a horizontal position, the lower end of the slot 23 will be engaged by the lug 25 and thus further movement of the arms checked. This is desirable, since further movement of the arms, below horizontal would again bring the shade closer to the Window.

The lengths of the bracket and arm may be varied according to the size of the window or the room in which the device is to be mounted. Obviously, the device may be ap- When the arms plied to windows in any and all sorts of buildin s.

%)bviously modifications in form and structure may be made Without departing from 5 the spirit and scope of the invention.
