I ADJUSTABLE WINDOW SHADE HANGER Filed July 11, 1928 INVENTOR. Mu/AM 5. H14 1.

A TTOR NE YS.

Patented Apr. 28, 1931 UNITED STATES WILLIAM B. HILL, OF SAN FRANCISCO, CALIFORNIA ADJUSTABLE WINDOW-SHADE HANGER Application filed July 11,

My invention relates to improvements in an adjustable window shade hanger, and it consists in the combinations, constructions, and arrangements hereinafter described and claimed.

An object of my invention is to provide an adjustable window shade hanger that permits the shade roller to be lowered or raised on the window frame for aligning the roller with the top of the upper sash. This permits the upper sash to be lowered for the entrance of air into a room and does away with the disadvantage of having air blow against the top of the shade as is the case where the curtain roller is permanently secured to the top of the frame. Moreover, a greater quantity of air may enter the room due to this construc tion.

A further object of my invention is to provide a device of the type described which provides novel means for positively aligning the ends of the roller in substantially the same horizontal plane regardless of its position on the window frame. The device is also extensible so as to fit windows of varying widths.

Other objects and advantages will appear in the following specification, and the novel features of the device will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawing forming a part of this application, in which Figure 1 is a front elevation of the device shown operatively applied to a window frame;

Figure 2 is a section along the line 22 of Figure 1; Y

Figure 3 is a side elevation of one of the roller-supporting brackets;

"* Figure 4 is a section along the line 4 l of Figure 3;

Figure 5 is avertical section through the device; and

Figure 6 is a transverse section through a portion of the device.

In carrying out my invention, I make use of a window frame 1, which has the usual lower sash 2 and the upper sash 3.

On the frame 1, I mount two guides 4 and 0 5 which are disposed adjacent to the top of 1928. Serial'No. 291,968.

the frame and extend aconsiderable distance down along the sides of the frame.

Reference to Figure 2 shows that these guides are channel-shaped and are provided with slots 6 and 7 on their inner faces. F Within each guide, I mount a rack. Reference numerals 8 and 9 designate these racks in Figure 2. j

A roller 10 extends between the guides 4 and 5 and is carried by brackets 11 and 12. to Each bracket is identicalwiththe other with the exception that they are'right and lefthand and that one has a hole while the other has a slot. A projection 13 is carried by both brackets (see Figures 3, 4 and 5), this projection being connected to the operating mechanism hereinafter described. p

The forwardly-projecting portions 14 of the brackets 11 and 12 are provided with a slot and a perforation respectively. Figure 5 shows the bracket 12 with aperforation therein. U-shaped members 16 and 17 are disposed at the top and bottom of the'bracket 12 and straddle the rack '9. V'Vithin the U- s'haped member 16 I mount a pinion 15. This pinion carries a shaft 18, and the shaft has a squareend entering a square opening in the pinion for positively connecting the two together. The pinion meshes with'the rack 9.

The bracket 11 carries a. pinion 19 similar 'tothe pinion 15 (see Figure 2), and the pun ion 19 is positively connected to a sleeve 20 that telescopes on the shaft 18 (see Figure 1). Figure 6 shows how the sleeve 20 and the shaft 18 engage with each other so that a rotation of the shaft will rotate the sleeve.

A tubular member 21 (see Figure 1) extends up into the guide 5 and has its upper end fashioned into a hook 22 (see Figure 4L). This hook passes through an opening in the projection 18, and a movement of the tubular member 21 vertically will raise or lower the bracket 12.

This, of course, will carry with it the pinion 15 and cause it to rotate. The pinion in turn being operatively connected to the pinion 19 will cause the latter to rotate. In this way, the brackets 11 and 12 are kept aligned at all times, and, consequently, the shade roller is properly supported.

manner.

The tubular member 21 slides over a guide rod 23 (see Figure 1). The lower end of this rod is secured to the window frame 24. The member 21 is held in adjusted position by a set screw 25.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood.

The shade roller 10 is mounted upon the brackets 11 and 12 in much the same manner as a standard shade roller mounting. The only difference is that the brackets are movable. Should a person wish to open the top of the window, the shade roller could be lowered to the desired point and then the sash opened. The lowering of the shade roller is accomplished by first loosening the set screw 25 and then pulling downwardly upon the member 21. This will move both brackets downwardly to the desired position. The shade 26 can be raised or lowered in the usual The telescoping members 18 and 20 permit the device to be attached to win dows of various sizes.

Although I have shown and described one embodiment of my invention, it is to be understood that the same is susceptible of various changes, and I reserve the right to employ such changes as may come within the scope of the appended claims.

I claim:

1. An adjustable shade roller hanger comprising tubular guides secured to a window frame in spaced parallel relation, each guide having a slot extending along its length in the portion which faces the other guide, a rack mounted in each guide, a shade roller supporting bracket having U-shape-d portions slidable in each guide and straddling the rack, a pinion carried by the U-portion of each bracket meshing with the rack, and means extending through the slots in the guides and operatively connecting the pinions together.

2. An adjustable shade roller hanger comprising tubular guides secured to a window frame in spaced parallel relation, each guide having a slot extending along its length in the portion which faces the other guide, a

rack mounted in each guide, a shade roller supporting bracket having U-shaped portions slidable in each guide and straddling the rack, a pinion carried by the U-portion of each bracket meshing with the rack, means extending through the slots in the guides and operatively connecting the pinions together, and means'for adjusting the brackets longitudinally of the guides.
