SHADE-PULL.

SPECIFICATION forming part of Letters Patent No. 293,31l, dated February 12, 1884.

Application filed November 15, 1883. (No model.)

To all whom it may concern Be it known that I, CHARLES WV. CLARK, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Shade-Pulls, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a side elevation of a shade-pull embodying my invention. Fig. 2 is a longitudinal section thereof. Fig. 3 is an enlarged view, in section, of a portion of a modification thereof. Fig. 4 is an end view of Fig. 3, the ball being removed.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists of a shade-pull hav- 7 bore or opening leading to the upper side of the bar, as at b, and into said openings are inserted theends of the cord B, it being noticed that said cord is looped and has attached to its center or top bend a hook, eye, or other means of connection, as at 0, of thepull with the shade or other article with which it is employed. The tubular ends of the bar are split ordivided and somewhat tapering, and receive within them the ends of the cord B, it now being seen that when the balls are fitted on said tubular ends of the bar they contract and compress the same,.and thus firmly clamp the ends of the cords in position within the ends of the bar, whereby the cord and bar are connected in a secure, reliable, and inexpenwhich is shown on the left side of Fig. 2, the

knots or nnknotted ends, as the case may be, being concealed by the balls.

In order to prevent swinging around or turning of the pull, I stiffen the cord B by Wire (1, (see Fig. 3,) and employ a slide, D, which is forced down over the cord below the top bend or angle, so as to double the cord, the diverging cord below the slide being drawn tightly by said slide, so as to render the diverging portions comparatively rigid and prevent them, and consequently the pull,from turning around after being adjusted on the shade.

If desired, the bar may be tubular throughout. I

Having thus described my inv'ention,what I claim as new, and desire to securerby Letters Patent, is 1 1. A shade-pull having a bar, end balls, and a suspensiomoord, the latter having its ends fitted in the bar and secured by the balls, sub stantially as and for the purpose set forth.

2. In a shade-pull, a bar having its ends tubular and compressible, a suspension-cord having'its ends fitted in the ends of the bar, and balls which are fitted on the ends of the bar and clamp the same on the cord, combined and operating substantially as and for the purpose set forth. a

3. A shade-pull having a bar, a suspensioncord, and slide, said cord being stiffened and said slide tightening the stifiened cord, substantially as and for the purpose-set forth.
