WEIGHT-CORD AND ATTACHMENT FOR WINDOWS.

SPECIFICATION forming part of Letters Patent No. 326,392, dated September 15, 1885.

Application filed May 20, 1885. (Model.)

To all whom it may concern.-

Be it known that I, EDWARD T. BRADBURY, of Mahanoy City, in the county of Schuylkill and State of Pennsylvania, have invented new and useful Improvements in Weight- Cords and Attachments for Windows, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a sectional elevation of a part of a window sash and frame, showing the ap-- plication of my invention; and Fig. 2 shows the cord and its attachments.

The invention will first be described in connection with the drawings, and then pointed out in the claims.

The cord a has the metal block I) attachedto one end, and the screw-clamp G and hook d attached to the other. The hook d is for holding weight 6, that moves up and down in the channel f, made in window frame A. as the Window B is raised and lowered. The cord or, when applied for use, passes over pulley g in the ordinary way. The block b is for attaching cord a to the window B, and is a plain block of metal formed with passage h to receive the end of the cord, and with the thumb-screw i for securing the cord; and for making the attachment of the block to the cord more secure I form an opening, j, in the block opposite the screw-threaded opening 2', that receives the screw 2', so that when the screw is turned down upon the cord a portion of the cord will be pressed into the openingj, thus preventing any slipping of the cord.

The clamp O is made with two parts or sections, a o, and a nut or sleeve, is. The sections 0 c are screw-threaded upon their outer surfaces, and correspondingly recessed at their adjacent surfaces, as shown at 0 to form a circular cavity for the end of the cord (1. Upon the parts or sections of the clamp O is screwed the internally screw-threaded nut or sleeve k, which serves to press the parts 0 0 together to cause them to grasp the cord a. The nut or sleeve is shouldered at-k, to hold the hook d, which is formed with ring (1 to encircle the clamp O and rest upon the shoulder is, as shown clearly in the drawings. The parts 0 o are knuckled togetherthat is,

the part c is recessed at c and the part c is formed with an enlargement, c, to fit in recess c to form a rocking center or fulcrum on which the parts 0 0 open and close. With this construction, when the nut or sleeve is is screwed below the enlargement and recess 0 c, the upper ends of the parts 0 0' may be opened to insert or remove the end of the cord a without entirely removing the nut or sleeve. The end of the cord being inserted,

- it is only necessary to screw the nut upward upon the sections a 0, which will close them upon the cord and cause them to grasp it as ,in a vise.

To prevent all danger of the cord slipping between the sections 0 c, I form them with the ribs or teeth 0 in the cavities c", which teeth will be embedded in the rope when the sections are pressed upon it, as will be understood from Fig. 2.

The block bis of a size to be inclosed by the. cavity Z, made in the edge of the sash B below the shoulder m, so that it will not interfere with the up-and-down movement of the sash. With this block, in case the cord a requires to be shortened, the stop-bead has simply to be removed from the windowframe, the window swung out at the top, the thumb-screw t loosened, and the cord drawn through the block and the screw tightened upon it again, all of which can be quickly and easily done.

The clamp C may be very easily and quickvent the raising or lowering of the window.

Having thus described my invention, what,

I claim as new, and desire to secure by Letters Patent, is

- l. The screw-threaded sections 0 c, in combination with the screw-threaded sleevek and hook d, the sections 0 0 being formed with shoulder k and the hook with ring d, substantially as described.

2. The externally screwihreaded sections 0 a, recessed, as shown at c, and formed, respectively, with the recess 0 and enlargement 0, in combination with the screwthreaded nut or sleeve is, substantially as and for the purposes set forth.
