useful lVindow-Shade;and I dohereby de: clare that the following is a full,- clear,

and exact description :thereof, reference. be- 111g had to the accompanying. drawings, 1n

which like letters refer to like parts.

This invention relates to. improvements in I shade hangersand particularlyito that class wherein the shade issuspended and; operated by means of a cord and pulleys. Onegfeature;

of the invention is them'anner of attaching the cord employed for suspending-the shade. and the roller construction.attachedto the shade. A further feature of the invention is to so attach the cord to theroller, upon the shade, that the upper bar of the. shade will extend slightly rearwardly-at, its upper edge.

when the weight of the curtain is. directed upon the part of the cord sustaining theweight of the shade, and a further-feature of the invention is to so construct thatpor tion ofthe roller supporting frame on the shade to which the cordis attached that when a downward pull isgiven to, the cord toraisethe shade to a folded position, it will cause the upper bar of the shade to, assumean upright position and extend in direct alinement with the remainder of the shade,

whereby the parts of the shade may be, folded together without undue friction or. part of the shadelupon the catching of one another part.

The. full nature, of this inventioniwill be understood from the accompanying drawings and the following description and claims Figure 1 is an elevation of a window frame showing the shade suspendedtherefrom and in partially folded .posltlon. Flg.

2 isa sectional view thereof as seen online 2-2 of Fig. 1. Fig. 3 is. an. end: elevation of the roller used in connection with. the:

shade. Fig. .4 is a front-elevation thereof and Fig. 5 shows a different form of roller construction and manner of attaching the end of the supportingzcord'thereto. I

Referring to the drawingsin which similar reference numerals designate corresponding parts throughout the several: view-syl indicates a window framewhich may be: of any preferred construction and .2 indicates a shade, preferably of fabric, which is provided at its upper and lower ends and'subsaidroller being of the usual. stepped variety so, that when the cord is in. one position on the roller, it/willzbind on. parts of the roller andrpreventthe cord from passing over the roller and whenmin another position will readilypass over the roller and permit the curtain to' bodily descend. I

One-endof the cord 6 is attached to. a

bracket :9;on:the roller carrying frame 10,

said bracket being preferably angular and the horizontal portion'll thereof provided witha recess 12 for the'reception of the cord 6, :the vertical portion of the-bracket 11 having? arms-13 .in the form of hooks around which the cord passes; attachedto the bracket 9, by-formi'ng a' knot 1.4 on the loose end of the cordwhich is placed above. the horizontal portion -11, the cord (ibeing then brought downthrough the recessj12 and extended below the arms-13 and then; extended upwardly and again through the. recess '12, said recessbeing provided with a registering way 15 through whichthe parts of the'cord may be introducedinto thejrecess. Q

Instead of forming a knot it at the end of the cord, any suitable. form ofbutton or enlargement may be provided for 1 preventing; the end from pulling out Yofthe recess.

The arms .13 extend forwardly aIlessldi stancerthan the horizontal portioirll of the bracket s0 thatiwhenthe weight of the shade is: directed againstthe cord the upper bar 3 to. which. the frame 10 is attached, will be directed at..an inward. inclination toward the frame asbest shownsin Fig. 2,'the cord causing .aslight rearwardlpressure on the. upper portionof the bracke 'In order :to raise and fold the lower portion of the "shade without moving the shade bodily, the cord after passing over the bracket 9 and the'roller 7 ,is introduced over a:roller 16' carried byithe frame 10 and througheyes 1 7: and 518; on. the

bars

5 and, 4 respectively, the end ofcthe cord being attached to the eye. 18 in any suitable manner. The roller 16 is constructed similar to the roller 7 so that when the-cord is at one point on the roller it will freely pass over the roller, but when moved to other parts of the roller it will bind againstthe framecarryingthe The cord is a roller and prevent further movement of the cord. i

In Fig. 5 of the drawings a slightlymodi- V or otherwise secured to the remaining portion of the cord at a point above and at the longitudinal center of the frame 10, and as the openings 21 are positioned forwardly of the back face of the frame 1O said frame and the bar attached thereto will likewise be tilted rearwardly when the weight of the curtain is suspended on that portion of the cord between the frame 10 and the upper roller 7 r In operation, when it is desired to admit light into the building through the lower portion of the window, a downward pull is given to that portion of the cord 6 passing over the roller 16 so asto move the bar 4 and the part of the curtain attached thereto upwardly, such downward pull causing the bar 3 to assume a vertical position and extend directly in line with the shade depending therefrom, thereby permitting the lower portion of the folding portion of the shade to pass upwardly over the face of the remaining portion of the shade without catching on any part thereof or without undue friction, so that said shade will be smoothly and uniformly folded.

\Vhen the lower part 4 has been moved upwardly and into engagement with the middle bar 5, said bar 5 and the portion of the curtain above the same will also be folded in the same manner as the part'of the shade is folded below the middle bar, thus permitting the shade to be assembled or brought together in the same manner, so as to occupy a minimum amount of space. As soon as the pull on the cord 6 is released the bar 3 will instantly return to its inclined position and will remain in said position until such time as the cord is again given a downward pull. If it is desired to lower the shade bodily a pull on that portion of the cord extending over the roller 7 is made which will move the cord to a portion of the roller 7 where the cord will readily travel over the roller and permit the shade to descend. As soon as the shade has been lowered or raised a proper degree,-the cord is again caused to travel over the enlarged Copies of this patent may be obtained for portion of the roller 7 so as to bind the cord against the parts of the frame carrying the roller 7 and thus stop a further descent of the shade.

. The invention claimed is 1. In "a shade hanger, the combination with a fixed pulley, a shade structure, bars on said shade structure, a pulley construction on the bar at the upper end of the shade, a cord for operating said shade, a bracket comprising a vertical portion integral with the rear edge of the pulley construction and a horizontal section integral with the upper end of the vertical portion and extending forwardly over the pulley construction, and means to attach the cord to the forwardly extending portion of the bracket in such a manner as to cause the upper bar to be rearwardly inclined when the weight of the shade is suspended from the cord and to assume an upright position when a pull is given parts of the cord,

7 2. In a shade hanger, the combination with a stationary pulley and a cord passing thereover, of a shade, a bar at the upper end of said shade, a pulley carrying frame attached to said bar, an upwardly and forwardly extending bracket on said frame, and means'to attach the cord to the forwardly extending portion of said bracket whereby said bracket and bar will be slightly rearwardly inclined when the shade is suspended from the cord and brought to an upright position when a downward pull is given to that portion of the cord passing through the frame attached to said bar.

3. In a window shade structure, the combination with a stationary pulley and a cord passing thereover, of a shade, a bar at each end of the shade and at the longitudinal center thereof, a frame carried by one of said bars, a bracket carried by the frame comprising a vertical and horizontal section, said horizontal section having a recess for the reception of said cord, and arms on the vertical portion of the bracket around which the cord extends.

4c. The combination with a shade and a bar at the upper end of the shade, of a pulley construction attached to said bar, a cord for cooperation with said pulley construction, and means to attach the cord to said pulley construction forwardly of the rear face of the pulley construction whereby the pulley construction and parts attached thereto will be normally rearwardly inclined.

In'witness whereof, I have hereunto affixed my signature in the presence of the witnesses herein named.
