CURTAIN-FIXTURE.

SPECIFICATION formin part of Letters Patent No. 324,959, dated August 25, 1885.

Application liled September 22, 1884. lNo model.)

To all whom it may concern:

Be it known that I, FRANKLIN ROOT, of Hartford, in the county of Hart-ford and State of Connecticut, have invented certain new and useful Improvements in Curtain-Fixtures, of which the following is a full, clear, and exact description, whereby a person skilled in the art can make and use the same, reference being had to the accompanying drawings, and the letters of reference marked thereon, where Figure 1 is a view in elevation of my improved fixture, showing the parts connected and in use. Fig. 2 is an edge View in elevation of same, looking from the right. Fig. 3

is a detail view, on enlarged scale, in vertical section, through the endless cord, pulleys, and the bearer. Fig. 4 is a detail rear view of part of the cordstrainer frame.

My invention relates to certain devices more particularly adapted for use with a roller and shade that are borne in movable supports and not held in fixtures, as most commonly used. It consists in certain improvements in the details of the curtain and the cord-supporting device, as more particularly hereinafter described.

In the accompanying drawings, the letter a denotes a window-frame; Z), the window; 0, pulley-blocks that are fastened to the upper part of the frame at each side of the window by means of screws 0', that also serve as pivots for the rollers 0 (Z, a spring-roller of any ordinary construction; 0, a shade borne on the roller in the usual way; f and f, supports or bearers, into which the pins or trunnions of the roller are fitted and held in such manner that the shade or curtain may be raised or lowered in the usual manner.

The bearer f is elongated in outline, and has at its upper end ahook f by means of which it can be readily attached. to a cord which supports it. A central opening, f, in the bearer has at its lower limit a narrowed socket with parallel sides,into which the squared end of the spring-spindle d fits, so as to be held against rotation. Arms f project from the bearer near its upper and lower ends, and have open sockets, through which the cord 9 passes and serves to prevent the bearer from being rotated under the impulse of the spring in the roller when the shade is unrolled.

While the bearer f supports one end of the curtain-roller and allows the pivot of the roll to turn freely in it, the bearer f has, as above described, the double office of supporting one end of the roller and also so holding the end of the spring-spindle as to prevent it from turning, the endless cord 9 being drawn suffieiently taut to hold the bearer in substantially a vertical position when the cord 0 is being unrolled or rolled up.

The endless cord {1 passes over the pulley in one of the fixed blocks 0 near the top of the window-frame, and over the cam-pulley h of the cord-strainer 71 the latter being fastened to the frame of the window, preferably directly below the fixed block that supports the cord. To this endless cord 9 is secured a cord, g, that also passes over the pulley and is connected to the bearer f, and still another cord, g passes over the same pulley, across the window-frame, over the other pulley, and is attached to the hooked upper end of the bearer f, that supports the farther end of the curtain roller.

The metallic frame 2' of the cord-strainer it may be attached to the window-frame, as by means of screws. It has aguide-slot, 6, along the greater part of its length, and fixed between its opposite ends is a screwrod, *5, along which the slide h moves freely, except when its play is limited by means of the milled nut i.

The legs of the slide move in the guide-slot i of the frame 13, one of them being notched, so as to prevent the slide from being pulled outward,and the other being merely narrowed, so as to fit into the slot. The lower part of the frame under the roll is cut away (see Fig. 0 2) for the ready introduction of the endless cord in putting up the fixture. The cam-roller h is provided with any desirable number of cams, and the curtain-roller is held at any desired height in front of the window by jamming the cord between the frame and the slide, as illustrated in Fig. 3.

The slide is hooked into the slot of the frame 2 of the cord-strainer, and the screw-rod hear ing the nut is then riveted in place in putting I00 the parts together for use, and when the currain-roller and the other parts are connected,

as herein described, the curtain is easily adjusted so as to exclude the light from the whole 5 or any particular part of the window.

I am aware that curtain-fixtures have been made with movable roller-bearers and having the roller and curtain vertically adjustable by means of endless cords, as shown in the 10 patent to WVerner, September 24, 1872, No. 131,648, and to Prindle, May 16, 1871, N 0. 114,852, and such I do not broadly claim.

I claim as my invention 1. In combination with the suspended cur- I 5 tain-roller with cords, bearers, and fixed supports, substantially as described, the cordstrainer h, consisting of the frame having a guide-slot, afixed screw-rod, a check-nut, and a slide bearing a cam-roller, all substantially as described. 20

2. In combination with the endless cord 9 of a curtain-fixture, the cord-strainer h, having the slide h open on the lower side for the ready introduction of the cord and bearing the cam-roller h, the screw-rod, and the check- 25 nut, all substantially as described.
