FASTENERS;

Specification forming part of Letters Patent No. 139,228, dated May 27, 1873; application tiled February 17, 1873.

To all whom it may concern:

Be it known that I, JoHN P. AHNoLD, of the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Window- Shade Fixtures, of which the following is a specification The object of my invention is to provide a device for tightening the cords of window shades or blinds, which shall embody in its construction the features of economy an simplicity, and be easily and efficiently operated, without danger of breakage or derangement of its parts.

My improvement, which consists of a novel method of combining the bearing piece of a cord-pulley with guides and an adjustingscrew, is herewith fully set forth.

In the accompanying drawing, Figure 1 is an isometrical view of a window-shade fixture, embodying my improvement; tudinal central section of the same; and 3, an isometrical view, taken from the rear, of a portion of the bracket.

The bracket or bed-piece A of my improved window-shade fixture is secured to the windew-frame by screws or nails 1) 0, one of which, a, engages in a recess, a, near the lower end of the bracket, the sides of the recess being beveled outward from top to bottom; and the other, b, passes through a lug, a, at t e opposite end of the bracket, the screw or nail 0 being first driven into the window or frame, leave only its head projecting, over which the recessed end of the bracket is slipped, and the screw or nail b then driven into sides of which are inclined or beveled outward from its top, is formed in the bracket A, from its upper to within a short distance of its lower end, at which'point the bracket is extended outward and downward to form a and convenience.

nut A. cord of upon a shaft secured into lugs, formed bearing piece, B, provid which fits into the inclined sides of which to dirept the bearing-piece in The pulley B, around which the the shade or blind passes, rotates on a its movements 7 It is obvious that the recess a and u? might straight sides and projecting described and shown, without departing from the principle of my invention, but I prefer the form described, on

In the use of my improved windowshade fixture, the tension of the shade or blind cord can be easily regulated by a slight movement of the adjustin g-screw, and from the simplicity of its constructon and mode of operation it has but little tendency to be broken or deranged.

I claim as my invention, and cure by Letters Patent- The combination, in ture, of a bracket,

a in its face, and a nut A, at or near its lower end, with the sliding bearingpiece B, and an adjusting-screw, G, to operate it, in the manner and for the purpose herein shown and described.
