ADJUSTABLE WINDOW-SHADE FIXTURE.

SPECIFICATION forming part of Letters hPatent No. 741,609, dated October 13, 1903. Application filed June 6, 1902. Serial No. 110,531. (No model.)

I accomplish the objectby the devices de-` scribed herein, and illustrated in the accompanying drawings, in which- Figure l is an elevation of a window with a shade attached thereto by my improved tixtures. Figs. 2 and 3 are side views of the same. Figs. 4, 5, 6, 7, and 8 are details views of different parts of the xtures. p

In the drawings, A is the casing of the window B. To the top of the casing are affixed the cord-carrying fixtures C and D, one of which, D, is adapted for the passage therethroughor thereover of two cords, the other, C, being for a single cord. VThese fixtures may be made with pulleys or may be arranged so that the cord will slide thereon. I prefer pulleys. The window-shade E is affixed to a spring-operated roller, having pintle F at one end and the spring'operated spindle G at the other end. AffiXed to spindle G by set-screw H is hanger-bar I, to which one endV ofthe adjusting-cordJis tied. From this bar the cord passes over pulley in Xture-C, thence over one of the pulleys in xture D, Vthence down through buckle K, thence through camclamp L, fastened to the lower portion of the casing, thence (after allowing a sufficient length for the adjustment of the shade) back through the clamp and the buckle up over l the other pulley in xture D, and thence down to han ger-bar M, to which it is fastened. On the bottom of hanger-bar M isa hook M', which hooks over and into the groove N of cylinder N, which *cylinder is fastened o n the end of pintle F by set-screw O. The hook passing into the groove is prevented thereby from slipping off and permits the cylinder to rotate therein.. If desired, hangerbar M could consist of a piece of strong wire with an eye at each end, one eye being for ,other being for the reception of a screw, which could be screwed into the end of the shade-roller in place of the pintle. It will be observed that the adjusting cord passes through the handle L ofthe clamp L both on its downward and upward movement and is kept separated by a web L, which prevents the cord twisting. .Thisalso enables me to operate the clamp by means of the cord, as by vp ulling the lower end of the cord out and away from the casing the grip Vof the clamp is released, and when the shade is adjusted `to its proper position by pulling down on the cord to draw it in close to the casing the clamp again grips the cord and fasf tens it. It will be observed that the weight of the handle of the clamp will cause the clamp to bind the cord within an inch or two without any downward pull on the cord. By the use of the buckle the portions ofthe cord which run over the pulleys in the fixtures can be adjusted relative to each other, so as to hold the shade-roller level and thereafter to retain it level, as it vdoes not make any difthe attachment thereto of the cord and the ference which part of the cord lcatches in the clamp, as both portions are held at the buckle in the same. position relative to each other that they had before being moved. When the stiffening-bar or curtain-stick at the bottom of the curtain is not long enough, I attach catches P on the ends thereof to prevent the lower end of the curtain from passing between the hanger-bars and thereby unwinding'the spring.

In practice I prefer to have the curtainstick long enough to prevent the free end of the curtain from passing between the hanger' bars.

Sov

Havingl described my invention, what I" claim as new, and desire to secure by Letters Patent, isv v l. The combination with a window-casing of a shade attached to a spring-operated roller, said roller having a pintle at one end and a spring-actuated spindle at the other end; a hanger-bar rigidly attached to said spindle;

a grooved cylinder rigidly attached toV said roo y pintle; a hanger-bar on said cylinder adapte ed for the rotation therein of said cylinder; fixtures attached tothe top of the casing one on each side thereof adapted for the passage thereover ofthe adjusting-cord; a cam-clamp aflixed to one side of the casing, said clamp having a handle; an adjusting-cord affixed to the saidhanger-bars passingthenee overthe fixtures at the top of the casing and thence down through the clamp; an adjusting-buckle on said adjusting-oord intermediate said clamp and the fixture above it.

2. An adjustable supporting device for curtain and shade rollers comprising a hangerbar rigidly afxed tothe spindle of the shaderoller; a hanger-bar revolubly connected to the other end of said roller; fixtures rigidly attached to the casing at the sides of the top thereof; a cam-clamp having a handle, said handlehaving two holes in the free end thereof; an adjusting and supporting cord attached to said hanger-bars and passing over said fixtures,and through said clamp and through the holes in the handle thereof; in combination with a spring-actuated shade-roller.

In Witness that I claim the foregoing,r I have hereunto subscribed my name this 30th day of May, 1902.
