WINDOW-.SHADE FIXTURE.

SPECIFICATION forming part of Letters Patent No. 519,437, dated May 8, 1894.

Applicationale March 6. 1894.

Serial No. 502.521. (No model.)

, To all whom t may concern:

Be it known that I, HERBERT R. SMILEY, a citizen of the United States, residing at Chicago, vin the county of Cook and State of Illinois, have invented certain new and useful Improvements in Window-Shade Fixtures, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates more specifically to that class of window shades known to the trade as drop lift roller curtains.

My invention is mainly characterized by two drop lift roller curtains, the ixtures of which are so arranged that the shades are free to overlap each other to any degree it may be desired to adjust them for the purpose of excluding the light more or less from the whole or any part of the window, all as more fully hereinafter described.

In the drawings, Figure l is an elevation of a window to which myim proved window shade fixture is applied. Fig. 2 is a vertical, central section thereof, substantially on line fr fr. Fig. 3 is an enlarged vertical section ofthe central cord guides on line 'y y Fig.1. Fig. 4 is a detached perspective View of one of the two central cord guides, shown in Fig. 3. Fig. 5 is an enlarged side elevation of the curtain roller guides. Figs. 6 and 7 are detached perspective views of the corner cord guide pulleys as indicated by their letters of reference. Fig. 8 is a detached perspective view of one of the bracket boxes of the roller carrying frame.

A represents a pair of vertical guide rods secured by outwardly projecting brackets B to the face of the stile of the window casey ment. A represents a similar pair of vertical guide rods secured by laterally projecting brackets to the inner sides of the window easement on opposite sides of the window. These guide rods are secured in their brackets by being provided with heads A2 and straining nuts A3 screw threaded upon the, lower ends whereby the lrods may be firmly secured in place. Upon each pair of guide rods is a curtain roller carrying frame com-,1 posed of two bracket boxes C, connected together by a cross bar D. The bracket boxes are constructed in the usualmanner to receive the ends of the spring actuated curtain roller shades E E', which may be of any desired description, and by means of two perforated ears C they brackets sli'dingly engage upon the guide rods. The arrangement of these guide rodsl and roller carrying frame is such that the two curtain rollers and shades are entirely out of the way of each other, when moved up or'down on their respective guide rods.

, Each of the roller carrying frames is provided with adjusting cords for raising and lowering the same and these are constructed in the following manner: The frame carrying the roller E is raised by means of two cords-F secured to the brackets C, then extending'upwardly pass over guide pulleys G near the opposite corners of the window frame and thence inwardly to guide pulleys in the center of the frame. These center guide pulleys are contained in a metallic housing H provided with ears I for securing the housing to the c asement. In the lower portion of this housing are journaled on opposite sides two suitable pulleys J and in front thereof at right angles a cord pulley K. The cords F after passing over the pulleys G pass into the housing beneath the rollers J and then upwardly together over the pulley K and thence some distance down in front of the window, with their ends joined together and provided with a suitable handle L.

Above the cord pulley K in the housing is pivotally secured a lever, provided with arms M, M', M2, the arm M projects forwardly underneath a projecting part of the housing, and a spring N is interposed between said arm and housing. The arm M2 projects to the rear and has secured to its end a cord O which projects ldownwardly in front and terminates in a suitable handle P. The arm M of the lever projects down on top of the roller K and is pressed by the spring N to nip both cords F in passing over the roller, the arrangements being such that by pulling upon the cord O the pressure of the lever is removed thereby allowing the free adjustment up or down of the roller carrying frame by means of the c'ords F.

The device for adjusting the frame of the .roller E is of the same description and operation except that the cord pulleys are substan- IOC tially in the vertical plane of the roller E', the housing containing the central rollers being secured to the underside of the top within the easement.

With fixtures of this description I am enabled to adjust the two curtains independently of each other and the curtains may overlap each other in any way without interfering and thus I can regulate the admission of light into the room in any desired manner.

Vhat. I claim as my invention is- 1. In a window curtain xture, the combination of two carrier frames, each carrying a spring actuated roller shade, two pair of vertical guide rods for said carrier frames, one pair arranged to guide one of the carrier .frames in the space within the window casement and the other to guide the other carrier frame in front and out of the way of the other, and two sets of cords for vertically adjusting the carrier frames independently 4of each other, substantially as described.

2. In a window curtain xture the combination of two spring actuated rollers and shades, a carrier frame for each, composed of two bracket boxes in which the roller is supported and of a bar connecting the bracket boxes, two sets of vertical guide rods, one secured by laterally projecting brackets inside of the window easement on opposite sides of the window, and the other byoutwardly projecting brackets to the stile of the casement, whereby the two carrier frames are out of the way of each other, and means for vertically adjusting each carrier frame independently of the other, substantially as described.

3. In a Window curtain fixture, the'coinbination with a curtain roller carrying frame slidingly engaging upon vertical guide rods, of two cords passing jointly over a single pulley secured centrally of the easement and from there outwardly and downwardly over suitable guide pulleys to the opposite ends of the roller carryingframe respectively, a spring pressed lever arranged to press upon tne top of the single pulley to nip the two cords and a releasing cord attached to the lever, substantially as described.

4. In a window curtain fixture, the combination of two spring actuated roller shades, carrying frames for each composed of two bracket boxes connected by a cross bar, two sets of vertical guide rods, one secured in the space between the easement, and the other to the face of the stile of the easement, and adj usting cords for each set of rollers each comprising two ropes secured to the opposite ends ot' the curtain carrying frame, guide pulleys for guiding the ropes to the center of the window easement and guide pulleys secured in a housing in the center of the easement, one of which is common to both cords, anda spring pressed lever acting upon said roller to nip the cords, and a releasing cord attached to said lever, substantially as described.

In testimonywhereof Iaftix my signature in presence of two witnesses.
