CURTAIN-POLE ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 366,330, dated July 1 2, 1887.

Application filed J uly 26, 1886. Serial No. 209,047.

T 0 all whom, it may concern.-

Be it known that I, GEORGE LOCKHARI, of New York city, county of New York and State of New York, have invented certain new and useful Improvements in Curtain-Pole Attachments, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention has relation to the attachments or appliances for curtain-poles, eornices, and other devices or media upon which curtains are sustained, which attachments or appliances are employed in shifting or moving the curtains or the curtain-sustaining rings back and forth upon the support.

The objects of my improvements are to produce simple, cheap, and durable appliances,

which may be readily connected with any cur-.

tain pole or rod, or cornice, or other support, which will be easy to operate, notliable to get out of order or to become disarranged, and which will obviate scratching of the rings against the surface of the pole or rod and undue wearing of the operating-cord. To accomplish these objects my improvements involve certain novel and useful peculiarities of construction and relative arrangements or combinations of parts, all of which will be herein first fully described and then pointed out in the claims.

In the accompanying drawings forming part of this specification, Figure 1 is a side elevation, and Fig. 2 a top or plan view, ofa curtainpole having my improvements applied thereon, the rings being shown in position to hold the curtains drawn back. Fig. 3 is a side elevation of the same pole, showing the curtainsupporting rings at intervals along the length of the pole, as when the curtains are' (No model.)

wherever they occur indicate corresponding parts.

It has not been deemed necessary to represent the curtains, inasmuch as they are attached to the curtain-rings in the usual manner and move with the rings.

A. represents a curtain-pole upon which the curtain-sustaining rings a a a are mounted and arranged to slide back and forth, the curtains being usually attached to small screw-eyes, as

a a, located in the rings, especially when the rings are made of wood.

B is the operating-cord by which the rings, and thus the curtain depending therefrom, are moved back and forth upon the pole. Near one end of the pole is a double-pulley block, 0, containing a pair of grooved sheaves to accommodate the cord. This block is connected withthe pole by a hollow shaft or stem, 1), large enough to permit the two sections of cord to run therein easily, and the block is mounted 011 the top of the pole and held in place by the hollow stem I), which passes through the material of the pole, the stem being threaded into the block and having a bead or rim, I), which bears against the under side of the pole. Instead of threading this stem into the block the lower end might be threaded and receive a nut, which would bear. against the pole and clamp the block in place; but the construction shown in the drawings is deemed preferable, because it gives a better and closer fiinish.

The pulleys or sheaves in the double block 0 are mounted upon horizontal axes, so as to better guide the sections of the cord into the hollow stem, and I prefer to place a partition between the two pulleys or sheaves, as shown at e, to aid in keeping the cord in place. At or near the other end of the pole is a singlepulley block, D, the pulley therein being preferably mounted upon a vertical axis and the block sustained by a solid stem, all, passing down through the pole and held by a nut on the projecting end.

The cord is carried up through the hollow stem b, over one of thepullcys in block 0, along the top of the pole, and between it and the rings made to engage with one of the middle rings, thence in the same manner between the pole and the remaining rings and back to one of the middle rings, to which it is attached, then between the pole and remaiuingringsover the second pulley in block O,and down through the hollow stem b. Being thus arranged, by pulling down on one end of the cord the rings will be drawn together at the ends of the pole, as in Figs. 1 and 2, and by pulling down on the other end of the cord the rings will (when the curtains are attached) be distributed along the pole, as in Fig. 3. While the rings are moving the pole is protected from wear by the intervening cord,which raises them off or away from the pole and makes it easier to slide the curtains, which are sometimes quite heavy, and prevents the inclination or wcdging of the rings to a great extent. The cord and pulleys being above the pole are not so much exposed to view as when placed below it, and the cord is prevented from sagging, and thereby detracting from the appearance of the curtain fixtures.

Instead of connecting the cord with the ring at the center I generally prefer to connect it with those next adjacent, by which a better movement of the rings is secured; but this is immaterial. v p

The connection between the cord and rings is generallymade by a simple turn of the cord about the rings, as shown, though any convenient means for connection might be em ployed instead.

I am aware that cords have heretofore been run along on the under side of the pole, and also that a cord has been run in a groove cut in the top of the 'pole, neither form, however, having the pulleys as herein described. In the first form the cord seriously interferes with the movement ofthe rings, causing them to drag on the top and sides, and the second form requires a groove to be cut out of the pole and the pulley to be located on one side, and is not applicable except upon poles of particular construction. My improved appliances are applicable alike to wooden or'metallie or covered poles, (wooden poles covered with metal,) whatever their-form or construc tion, and require no alteration in the pole save the piercing of two small holes for the stems of the pulley-blocks, and may be quickly applied upon old or new poles without the aid of special tools.

At Figs. 6, 7, and 8 the improved appliances are shown as mounted upon the inner face of an ordinary window-cornice. E represents the body of the cornice, usually hav- 7 ing projecting end pieces, as at E E. The single-pulley block is sustained in. ordinary screw-eyes e e, entering the material of the cornice, and the double-pulley block sustained in like manner by screw-eyes f f. A suitable rod, as A, serves to guide the curtain-rings,

(in this case usually smaller than those employed on the pole,) and the rod is sustained upon the cornice by screw-eyes, as g g, or by other suitable means. The cord is applied as before and the curtain is moved as before. The pulley-blocks are rigidly held in proper place by screwing the stem or nut so as to secure a firm bearing against the screw-eyes. In like manner the blocks maybe mounted upon the window-easing or upon any object of support. when desired, and generally they will be found to admirably answer the purpose or objects of the invention, as previously set forth.

Having now fully described my invention, what I claim as new, and desire to scan re by Letters Patent, is-

1. The combination, with a curtain-pole, of

' the double-pulley block for the operating cord, the same being provided with a hollow stem'passing through the body of the pole and receiving the cord, substantially as shown and described.

-2. In combination with the double pulley block, the hollow stem constructed and arranged substantially as described, and provided with a bead or rim at bottom to bear against the under side of its support and securely hold the block in place, for the purposes and objects set forth.

3. In attachments for curtain poles, &c., the double and single pulley blocks for the operating-cord, said blocks being provided with shanks or stems, one of which is made hollow or tubular, each arranged, as explained, to secure the blocks firmly in place upon the support, and each projecting entirely through the support, and combined with each other and with the support, substantially as shown and described.

4-. The combination of the pole, the curtainrings movable thereon, the operating-cord lo cated between the rings and the pole and preventing contact of the rings and pole, and the double and single pulley blocks mounted upon the top of the pole, and each provided with shanks projecting entirely through the pole, and with a nut or rim bearing against the under side of the pole, the shank connected with the double block being made hollow or tubular, substantially as shown, and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand in the presence of 'two witnesses.
