CURTAIN-FIXTURE.

SPECIFICATION formingpart of Letters Patent No. 234,177, dated November 9, 1880.

Application filed July 26, 1880. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH DARLING, of Peachville, in the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements in Curtain-Fixtures; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyin g drawings, and to letters of reference marked thereon, which form a part of this specification.

The invention relates to a class of windowshade fixtures in which the shade can be lowered from the top or elevated from the bottom, so as to exclude the suns rays from any portion of the Window or obtain ventilation above and shade below.

The curtain -roller is journaled in slides which move vertically. The roller on which the curtain is affixed can be raised and lowered by one mechanism, while the curtain itself can 7 be rolled and unrolled by another.

In the drawings, Figure l is a perspective View of the curtain with my improvement affixed to the window-frame. Figs. 2 and 3 show the slides in which the roller journals. Figs. 4-. and 5 are detailed views, showing the manner in which I affix the ends to the rollers.

The curtain itself is of any ordinary construction, and the roller is a cylinder of wood, to which the curtain may be attached in any convenient and proper manner.

At one end of the roller the grooved wheel 0 is firmly fastened. In this groove there is the endless cord D, to which is attached, by the hook E, the weighted tassel F. The weight ed tassel F is made sufficiently heavy to prevent the curtain A from unrolling by its own weight. The hook E is made of the peculiar form shown in the drawings, in order that turns of the endless cord D can readily be made upon it, in order to increase when necessary the friction of the cord D. The grooved wheel has two, three, or more points projecting from it, which pierce the end of the rollerB and thereby cause the roller B to turn when the grooved wheel 0 is moved.

I fasten the grooved wheel (J to the roller B by means of the adjustable screw H throughthe aperture G, leaving enough of the screw projecting, as shown in Fig. 5, to form ajournal for the roller B. The journal on the other end of the roller 13 is made by a similar screw.

The journal H is placed in the lower loop, K, of the wire support J. This support J is made in the form shown in Figs. 2 and 3, with the loop K, at the bottom, of a proper size to support the body of the screw H and smaller than the head of said screw.

The upper loop, L, is made sufficiently large to allow the head of the screw H to freely pass through it.

The wire support J is fastened by the band N to the heart-shaped slide M. The band N projects from the slide M sufficiently far to receive the wire guide 0. It is convenient, but not absolutely necessary, to strengthen the outer rim of the support J by a wire stay, 1?, and for use at one side of the roller this support P is useful, in order to form a guide for the main supporting-cords Q.

The wire guides 0 may be of any required length, but it will rarely be found necessary to have them extend farther than one-half of the length of the window. The wire guides 0 may be omitted, as the curtain will always hang on a plumb line, except when disturbed by wind. The cord Q, passing between the stay P and the wire support J, will sufficiently guide the curtain. When the wire guides 0 are dispensed with I recommend inserting nails at a point almost half-way down the window-casing, in order that the guides M may rest thereon.

The curtain is suspended by the cord Q, which passes over the nails It in the upper part of the window-casing. Said nails It may be also used to fasten the upper ends of the wire guides O.

The cord Q is fastened to the weighted tassel S, which may be sufficiently heavy to balance the weight of the curtain A and its fixtures, or the cord Q may be fastened on the nail T, or in any other convenient manner.

The slide M is made with the reins V and W, so that the upper part of the fork will be directed. to rest securely on the nails or supports, which form, also, fastenings of the wire guides 0, when such guides are used. The slide M is made of a flat piece of metal, so

that it will rest upon and slide freely up and down the window-casing.

I prefer to make the cord Q with a loop, in which the weighted tassel S may be suspended. and the ends of the cord Q are fastened at the upper loops, L, of the curtain-supports J.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of the curtain-roller B, grooved wheel C, journals H, wire supports J, and slides M, substantially as described, and for the purpose specified.

2. The combination of the curtain-roller provided with the grooved wheel G with the endless cord D and weighted tassel F, provided with a double-curved hook, E, substantially as described, and for the purpose specified.

3. The double-curved hook E, substantially as described, and for the purpose specified.

4. The combination of the slide M, band N, 20 wire support J, and stay P, substantially as described, and for the purpose specified.

5. In the curtain-fixture, a combination of the flat slide M with the wire guide 0 and a curtain-roller, substantially as described, and 2 5 for the purpose specified.

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

JOSEPH DARLING.
