WINDOW-CURTAIN FIXTURE.

SPECIFICATION forming part of Letters Patent No. 543,946, dated August 6, 1895.

Application filed May 23, 1895. Serial No. 5501 (No model.)

To all whom it may concern.-

Be it known that I, EDWIN 1. PYLE, a citihem of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Window Curtain Fixtures; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in window-curtain fixtures; and it has for its object to provide fixtures of such a nature that the curtain may be lowered from the top of the window at will, so as to admit of proper ventilation, and also to prevent any rattling that may be caused by a strong draft through the Window.

A further object of my invention is to provide a simple and effective device whereby the belt or adjusting-cord to which the curtain-roller is secured may be kept taut, so that the proper working of said cord is assured; and with these ends in view my invention consists in the various details of construction hereinafter described.

In the accompanying drawings, which form a part of this specification, Figure 1 is an interior perspective view of a window equipped Figs. 2 and 3 are detail elevations'of the bearings for the ends of the curtain-roller; Fig. 4, a section on the linex 0c of Fig.2; and Fig. 5a horizontal sectional view of a window-casin g, showing the grooved guideways in cross-section.

Similar numbers of reference indicate like parts in the several figures of the drawings.

1 is the window-casing, to the upper part of which is secured two double pulleys 2, (but one shown,) and 3 are two single pulleys, (but one shown,) which are secured at either side of .said casing near the bottom thereof.

4 is the adj usting-cord which passes around the pulleys after the manner of an endless belt, and is crossed at the top of the casing clearly shown in Fig. 4. The other ends of the cord are passed through eyes 8 in the ends of the swivels 9, which are secured to the lower part of the fixtures. One of tho fixtures 5 is provided with a keyhole-shaped aperture 10, as shown in Fig. 3, within which is inserted a headed journal (not shown) on one end of the curtain-roller. has a vertical slot 11, within which is inserted the flattened end of the spring-rod (not shown) of an ordinary spring-roller curtain, and is securely held within this slot by means of the set-screw 13.

Since both of the fixtures or bearings are exactly alike, with the exception of the shape The other fixture of the slots within which the ends of the curtain-roller are journaled, as previously described, I shall hereinafter only refer to one of these fixtures in describing the other elements of the same.

Referring particularly to Fig. 4, 1a is an antifriction-roller journaled between ears 15 (but one shown) rigid with the back of the bearing, 5. 16 is a rubber tire on said roller. 17 is a screw depending from the bearing'5, and 18 is a nut run thereon. 19 is an annular groove in the nut 18, and 20 is a tubular swivel having its upper portion formed into an annular flange 21, which fits within said annular groove 19 and serves to connect the nut and swivel together in such manner that said nut may be rotated independent of the swivel.

22 is a strip of wood or other material socured to the top of the casing 1, and 23 is a vertical groove or guideway in said strip, within which the roller 14 tracks, as shown in Figs. 1 and 5. By thus guiding the movements of the bearings for the curtain-roller and providing the antifrietion-roller l twith a rubber tire or buffer all unnecessary noise and rattling is done away with, especially the annoying rattle caused by a strong draft when the window has been opened at the top for the purposes of ventilation.

When the adj usting-cord has become loosefrom any cause it may be quickly and effectually tightened without inconvenience by sim ply turning the nuts 18.

I am aware that curtain-fixtures have been heretofore provided with means for lowering the curtain-roller from the top of the window to any desired plane, and I therefore do not claim this feature; but

What I do claim, and desire to secure by Letters Patent, is-

5 In curtain fixtures of the character de scribed, the combination of the adjusting cord, the pulleys around which said cord is passed, the bearings carried by said cord and in which the curtain roller is journaled, the

[0 screws depending from said bearings, the adjusting nuts on said screws provided with annular grooves, the swivels provided at one end with an eye and at the other end with an internal annular flange which engage the annular grooves on the adjusting nuts, substantially as and for the purpose described.

In testimony whereof I afiix my signature in presence of two witnesses.
