WINDOW SHADE.

Application filed September 6, i922. Serial No. 586,4;77.

T all whom it may concern:

Be it known that I, WALTER CHURCH, a citizen of the United States, and a resident of Greeley, in the county of Weld and State of Colorado, have inventeda new and Improved Window Shade, of which the following is a full, clear, and exact description.

My invention relates to window shades for curtains of the type including two shades or shade'portions, both adapted to be drawn from the sametroller in oppositedirections when such roller is located at a point inter V mediatethe top and bottom of the window,

: thus manipulating a window-shade so that on imparting a turning movement to the roller one curtain or curtain portion is drawnup to shadethe upper part of the window and the other is simultaneously drawn down to shade the lower. part of the window.

The particular object of the present in vention is to provide new and improved and very much simplified controlling means for of the above general character. I

I am, of course, aware that very many diiterent types of such controlling means have been proposed.

The object of my invention, however, is to. provide a novel controlling means having the particular advantages that, with a single roller, preferably a spring roller of the'well known Hartshorne type, and also with the lower curtain or curtain portion provided with the single short centrally pendant cord commonly pulled to raise or lower a single shade or curtain hung on such a roller located at the top of the window, the new. shade of'my invention may have its two curtain portions adjusted as desired'nierely by pulling said pendant cord in the usual manner and, therefore, merely by using one handatall times; while at the same time providing a reallyjpositive elevating means forthe upper-curtain by virtue of having elevating elements to act'- FREMONT cally, and thereby incidentally obviating cord complexities, and minimizing cord r QFICE,

lengths, the number and variety of cord guiding fixtures requiredfthe work of installing the entire curtain equipment and the manufacturing expense of the latter.

Other objects will be in part obvious'and in partpointed out hereinafter.

All the'objects will be more clearly understood from the following description-when taken in connection with the accompanying drawing showing one example of a possible manner'in which my invention may be embodied; it being, of course, understood that w the scope of protection contemplated is indicated by the appended claim l In this drawing, merely illustrative ofthe general chara'cterof the invention asabove. noted, and in which like charactersrefer to like parts throughout the several views, f

Figure 1 is a front elevation of a curtain equipment according tovmy invention;

F 1gure-2 1s a side elevation thereof; and. Figure 3 is an enlarged fragmentary view,

being a section taken onthe l ine'33 of Figure I? x i. From this drawing it will be seen that my improved 'window shade equipment comprises merely a pair of upper fixtures. 4, a pair of flexible elements '5 and a pair of drums 6 fixed on the outer ends of the curtain roller in combination with a curtain Hartsho'rne roller in the well known man-- ner in-the stock Hartshornebraekets 9, but,

. Further, I prefer to scam the upper free 7 end of upper curtain 7 in the usual manner, as indicated at 11, not only to prolong the life of the curtain, buta'lso to permit a light wooden. slat 12 to be, accommodated ple form and adapted'to be inexpensively fine the portion of the flexible element runv made from sheet metal, the bracket having journaled therein, one above theother, a

pair of short rollers or drums 13 and 14, over the upper one ofwhich the flexible element 5 is looped and-behind the lower one of which saidelement isguided to conning down to slatflQto a predetermined line of descent and to increase the frictional hold of the fixture on gits flexible element,

It :is, of course, immaterial whether or not the two curtain elements 7 and 8 are separate curtain members secured along their joined ends to the roller or are folded over portions of a-single curtain member secured along the line of fold to the roller, as shown in F igure; 3. It will be under- 7 stood, therefore, thatthe term curtain or herein above stated. v It will, of course, be understood, nevertheless, that thellnvention maybe variously curtain portion as employed herein refers to either type; of curtain element, that is, a curtain portion or a curtain member.

The operation of the above deviceshould be obvious. To simultaneously extend the two curtains or tosimultaneously retract thesame as desired, the cord 10 is merely pulled againstthe tension of the well known spring means within the Hartshorne roller; the action being precisely like the familiar one encountered. when using such a roller carrying the ordinary single curtain at the top of awindow. And it will also have been seen that I have provided an exceedingly simple, inexpensive, reliably- 0 eratin and com )arativel incons icuous I'D i construction and one otherwise well adapted to; attain all the various ends and objects carriedoutfwithout following the precise details of construction and arrangements of parts as particularly described in c'onnec: tion with theillustrative disclosure of the drawing so long as the spirit of the invention is adhered to as pointed outin the following claims r I claim: 7

.1.. I a window shade including a single roller having wound thereon a plurality of curtain elements adapted to be simultaneously unwound from the .roller one to ward the. top of the window and the other toward the bottom of the window, thecombination of drums fast on the respective ends of the roller, a plurality of drums on fixed axes directly above the respective betwee the drum last toward the bottom of the window, the'combination of drums fast on the;.rcspective ends of the roller, a plurality; of drums on fixed axes directly above the respective drums on the roller and-located at the top of the window, and a single flexible element secured atone endto each of the drums'on the roller and running thence upwardly over the overlyingdrum at the'top of the window and running thence downwardly'and having its other end secured to. thetop of the upper curtain element, there being associated 'with each drum at the top of the window a guidingaancl confining means for the flex ible element on that side of the window and engaging the part of said element extending mentioned and the upper curtain. 5 f

3.,In a window shade including a single roller having wound thereon a plurality, of curtain elements adapted to be simulta neously unwound from. the roller one toward the top of the window andthe other toward the bottom of the window, the co'nibination of drums fast on the respective ends of-the roller, a plurality of drums on fixed axes directly above the respective drums onzthe roller and located at the top of the window, and a single flexible element secured. at one end to each of the drums on the roller and running thence upwardly over the overlying drum at the top. of the window and running thence downwardly and having its other end secured to thetop of the upper curtain, there being an auxiliary drum located below each drum at the top of ward the top of-the window and'the. other toward the ,bottom o-f the window, thecom- 7 bination of drums fast on the respective ends of the roller, a plurality of drums on fixed axes directly above the respective drums on theroller and located at the top of the window, and a single flexible element secured at one end to each'of thedrums on the roller and running thence upwardly over the overlying drum at the top of the window and running thence downwardly and having its other end secured to the top of the upper curtain, there being an auxiliary drum located below each drum at the top of the window for frictionally engaging and additionally guiding the flexible element on that side of thewindow, and there being further provided a unitary'bracket having journaled thereon one of the drums at the top of the window and the auxiliary drum for the drum last mentioned. 7

5. In a window shade including a single roller having wound thereon a plurality of curtain elements adapted to be simultaneously unwound from the roller one toward the top of the window and the other toward the bottom of the window, the combination of drums fast on the respective ends of the roller, a plurality of drums on fixed axes directly above the respective drums on the roller and located at the top of the window, and a single flexible element of the upper curtain element, the upper curtain element having a transverse slat carriedthereby at its upper end, the ends of the slat protruding beyond the side edges of the upper curtain, one end of each flexible element being secured to one of the protruding ends of the slat.
