WINDOW-SHADE BRACKET.

Application filed February 19, 1923. Serial No. 619,811.

7 eye or the hook of the bracket and then being twisted and coiled upon itself to form a head or shoulder to limit the extent to which the bracket can be screwed into the.

window frame or the window frame sash, and also to act as a brace to take care of any stress or strain when in place.

Other novel features of construction and advantage will hereinafter more clearly ap pear in the detailed description and the ap pended claims.

For the purpose of illustrating my invention, I have shown in the accompanying drawing a typical embodiment thereof which is at present preferred by me, since this embodiment will be found in practice to give satisfactory and reliable results. It is, however, to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figures 1 and 2 represent, in perspective, window shade brackets, embodying my invention.

Figure 3 represents, in front elevation, a window bracket in assembled position with respect to a window frame and a window shade. Similar numerals of reference indicate corresponding parts.

Referring to the drawings p In accordance with my present invention, the brackets are formed from a single strip of material such as, for example, wire, one end of which is threaded to form a screw 1, the wire then extending outwardly and be ing deflected upon itself to form a coil 2 or a hook 3. Between the coil 2 and the screw 1 the wire is twisted upon itself, as indicated at 3, in Figure 1, and as indicated at 4, in

Figure 2, a tight twist preferably being formed. In proximity to the rear end of the screw portion 1, the wire is coiled upon itself, as indicated at 5, to form a head or shoulder which serves as an abutment when the bracket is screwed into its position on the window frame.

In Figure 1, the coils 2 are disposed in close substantially parallel relationship with each other. The head 5 is formed by windingrthe wire upon itself so that the turns of wirewhic'h form. the head 5 are disposed substantially in the same plane. The hook or loop forming portion 3 has the wire doubled to form two hooks lying one against the other and of the same dimensions.

Window brackets formed in this manner are very rigid and can be manufactured by means ofsuitable material at a very low cost of production, as it simply involves the bending and twisting of a single piece of material into the desired conformation and there is no waste of material in the manufacturing operation. The screw threaded portion can be threaded prior to the forming operation or subsequently thereto, as may be desired.

The manner in which the window shade roller 6 co-opera-teswith the bracket is well known to those skilled in this art and a detailed description thereof is believed to be unnecessary, it being apparent that the window shade roller co-operates with the bracket in the same manner as it does in the conventional types of brackets.

The head or shoulder of the bracket also acts as a brace to take care of any stress or strain to which the bracket is subjected when in place. 7 i

It will now be apparent that I have devised a new and useful window shade bracket which embodies the features of advantage enumerated as desirable in thestatement of the invention and the above description, and while I have, in the present instance, shown and described an embodiment thereof which will give in practice satisfactory and reliable results, it is to be understood that this embodiment is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages..

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, i 7

1. A window shade bracket formed from a single piece of wire the free end portion of whlch ls's'crew threaded, [the said wlre then extendlng rearwardly and. being doubled over upon itself to form a roller pin re-'- being spirally wound to form a snbstain'ially circular head arranged transversely with respect to said screw tl'ireaded stem.

2; A Window shade bracket -formed fronr a single piece of wire the free endportion of which is screw threaded, the wire then extending rearwardly and being doubled over upon itself in coiled form the axis of which coil is arranged at right angles to the longitudinal axis of said screw threaded end portion, said wire then being extended forwardly and twisted toprovide a reinforced or doubled portion the free end of which donbled portion thereafter being spirally coiled in a direction transversely of the longitn dinal axis of said screw threaded portion.
