CURTAIN-FIXTU RE.

SPECIFICATION forming part of Letters Patent No. 402,598, dated May '7, 1889.

Application filed Tannery 18, 1889. Serial No. 296,701. (No model.)

To whom it may concern.-

Be it known that I, PLEASANT B. HUFFMAN, a citizen of the United States, residing at Ohandlerville,in the county of Cass and State of Illinois, have invented a new and useful Improvement in Curtain-Fixtures, of which the following is a specification.

The invention relates to curtain-fixtures of that class in which a roller shade or curtain is adjustable vertically with relation to the window-frame, so that any desired portion of the window may be darkened by unrolling a part of the shade and adjusting it in the desired position; and the invention consists in the improved construction and combination of parts which will be hereinafter fully described, and particularly pointed out in the claims. I

In the drawings, Figure 1 is afront view of a window equipped with my improved adj ustable roller-shade, showing the latter partly unrolled and'lowered, so as to shade the middle part of the window. Fig. 2 is a front view showing the shade raised to the top of the window-frame and wound upon the roller. Fig. 3 is a perspective detail view of one end of the curtain-roller, showing how it is connected with. the operating-cord. Fig. 4 is a detail view of one of the links connecting the ends of the curtain-roller with the operatingcord.

The same lettersrefer to the same parts in all the figures.

In the drawings, Adesignates a windowframe of ordinary construction, at the top and bottom of which are centrally located screweyesB B while at the four corners are aciditional screw-eyes B B B and B.

0 is a light but strong operating-cord, which passes upward through the upper central screw-eye,B', thence laterally to one of the upper corners, through the screw-eye B at said corner, downward and through screw-eye B at the corresponding lower corner, thence to the lower central screw-eye, B up through the latter and through the upper central screw-eye, B, thence to the upper corner screw-eye, B down through the latter and through the lower corner screw-eye, B thence again to the lower central screw-eye, B and up through the latter. The ends of the cord are then tied together or otherwise suitably connected, thus making an endless cord, by pulling upon which at any point the sides or parts between the screw-eyes B B and B B will move simultaneously in the same direction.

In lieu of the screw-eyes, pulleys of any suitable construction may be used, double pulleys being of course necessarily put in the places of the upper and lower central screweyes, B and B D is the roller, to which is attached a curtain or shade, E. The ends of the roller are provided with annular grooves F, and it is attached to the endless cord 0 or the parts thereof between the corner screw-eyes, B B" and B B, by making a turn of the cord or winding it once around each end of the roller in the grooves F, which prevent the cord from slipping off.

To retain the shade-roller in the proper position upon the cord and prevent it from slipping or dropping at either or both ends, I employ the links G, (shown in Fig. 4 of the drawings,) which links may be constructed of wire, and consist of a central bent or curved porighgn, a, at the ends of which are formed eyes will fit over the front side of the roller, above and below which the eyes I) b are hooked or adjusted upon the endless cord 0, thus creating suiiicient friction to prevent the accidental displacement of the roller.

The shade E is provided at its lower end with the usual stiffening-slat, II, to the ends of which are attached a pair of loops, I I, through which the endless cord passes at the sides of'the window-frame. This is for the purpose of preventing the shade, when partly The bent middle portion of said links or entirely unrolled, from fluttering or being blown into the room when the window is open.

The ends of the roller are provided with laterally-extending pins J J, located axially with relation thereto. Near the u er end of IOO may be attached a ring or tassel, L, for unrolling the shade.

The operation of my invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. The shade may be unrolled to any desired extent by simply pulling the ring or tassel at its lower end. It may then be adj usted to any desired position by pulling upon the cord 0, preferably by grasping the parts of said cord between the central screw-eyes, B 13 \Vhen said parts of the endless cord are grasped and pulled upwardly, the sides of the cord between the corner serew-eyes,B l5 and B B, will travel downwardly, carrying the shade-roller; which is meanwhile retained securely upon the cord by the frictionlinks G G. In order to wind the shade upon the roller, the latter is first raised to the top of the window-frame by pulling the cord 0 in the proper direction until the pins J J bear against the under sides of the brackets K K. By cont-inning to pull in the same direction the roller will be revolved by the cord C being wound once around each end thereof, as desired. It will be seen that when this is done the position of the cord is shifted with relation to the roller .and the screw-eyes, the result of which is that the cord will not be worn excessively at any particular place, but gradually and evenly throughout its entire length, thus rendering it more durable and less liable to breakage. The general construction of the device is simple and inexpensive and it may easily be put up and manipulated.

I would state that it is not deemed necessary that the screw-eyes B B should be located centrally at the top and bottom of the window-frame, as they may be located near either side with the same results.

Having thus described my invention, I claim 1. The combination, with a window-frame, of screw-eyes located at the middle of the top and bottom of said frame and at its four corners, an endless cord threaded through the said screw-eyes, as described, crossing itself between the middle screw-eyes, and a shaderoller attached to the parts of the said cord between the upper and lower corner screweyes, substantially as described.

2. The combination, with a window-frame, of screw-eyes located at the middle of the top and bottom of said frame and at its four corners, an endless cord threaded through the said screw-eyes, as described, crossing itself between the middle screw-eyes, and a shaderoller having annular grooves near its ends, attached to the parts of said cord between the upper and lower screw-eyes by winding said cord once around each end of the roller in the grooves in the latter, substantially as set forth.

3. The combination, with a window-frame, of screw-eyes at the middle of the top and bottom and at the four corners thereof, an endless cord threaded through said screw-eyes, as described, a shade-roller attached to said cord by winding the parts of the latter be tween the corner screweyes once around each end of the roller, and friction-links having eyes, whereby they are adjusted upon the endless cord at each end of the roller, so as to bear against the latter, substantially as set forth.

at. The combination, with a window-frame, of screw-eyes at the middle of the top and bottom and at the four corners thereof, an endless cord threaded through the said screweyes, as described, a shade-roller attached to said cord by winding the latter once around each end of the roller, a stilfening-slat at the lower end of the shade, and loops attached to the ends of said slat and encircling the endless cord, substantially as set forth.

5. The combination, with a window-frame, of screw-eyes at the middle of the top and bottom and at the four corners thereof, an endless cord threaded through said screweyes, as described, a shade-roller attached to said cord by winding the latter once around each end of the roller, axial pins extending from the ends of the roller, and brackets secured near the upper corners of the windowframe to form bearings for the said pins, substantially as set forth.

(3. As an improvement in curtain-fixtures, the combination, with a window-frame, of screw-eyes at the middle of the top and bottom and at the four corners thereof, an endless cord threaded through said screw-eyes, as described, a shade-roller attached to said cord by winding the latter once around each end of the roller, friction-links adjusted upon the endless cord over and bearing against each end of the roller, axial pins extending from the ends of the latter, brackets secured near the upper corners of the window-frame to form bearings for the said pins, and loops at the lower corners of the shade encircling the endless cord, all arranged and operating substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

PLEASANT B. HUFFMAN.
