Description

UNITED STATES PATENT OFFICEO IMPROVED SASH-FASTENING.

Specification forming part of Letters Patent No. 56,347, dated July 17, 1866.

To all whom it may concern:

Beit known that I, BUnRoUGHs BEACH, of West Meriden, New Haven county, State of Connecticut, have invented new and useful Improvements in Window Sashes, and I do hereby declare that the following -is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the ac- 'companying drawings, forming part of this specification.

Thepresent invention relates to that class of supporters for window-sashes consisting of two sector-shaped spring-arms arranged and turning upon a common center pin or shaft at one end, and at their outer ends, which are serrated or roughened in any proper manner, bearing against the sides of the sash-frame, and thus preventing it from being either raised or lowered until removed from contact with the same 5 and it consists in a novel manner of operating these arms, whereby, when so desired, they can -be both so swung or turned and in conjunction with each other as to be entirely relieved from the sash, as will be apparent from the following detail description thereof, reference being had to the accompanying plate of drawings, in which- Figure l shows my improved sash supporter as inserted in a window-frame in proper position for its spring-arins to act or bear against the side of the sash; Figs. 2, 3, and 4, detail views of the sash-supporter detached from the window-frame. l

Similar letters of reference indicate like parts.

A A in the drawings represent the two sector-shaped arms constituting the sash-supporter, hung at one end upon a common center shaft or pin, B, of a casing or box, C, of suitable form for being inserted in the frame of a window and yet allow the serrated or notched ends D of the said arms to bear against the side of the sash. To each of these arms A a spiral spring, E, is secured at one end, its other being within and incased by a suitable casing or box, F, for each spring ofthe box C, by means ot' which casings F the springs are protected from injury and from getting out of place.

The sides ofthe arms A in contact with each other are similarly notched or cut away at G, as plainly shown in Figsland 2, so as to form a tapering opening, H, between the two, in which opening a wedgeshaped piece is inserted, secured to a knob, J, so that by forcing such wedge into the said opening the spring-arms A will be made to open or swing away from each other, thereby relieving their serrated ends from contact with the sash, as is obvious, both arms moving in conjunction with each other.

In lieu ofthe wedge-shaped piece I, (which I intend to so arrange in the facing of the window-fame that while it cannot become disengaged therefrom it can be pressed in at pleasure, the action of the spiral springs of the arms A throwing it o'ut,) a plate, K, turning upon a center pin, L, between the two arms A, and having a suitable handle-piece, M, for convenience in moving it, may be used, this plate bring placed in and between the two arms A, and in such position that when properly turned or operated through its handle M it will act against, by its oppo site ends, the two arms A, and open them Vboth from each other at one and the same time, as hereinbefore described for the wedgeshaped piece L, the principle of operation being the same, as is obvious.

I am aware that spring-arms of the form and shape hereinabove explained and shown in the drawings have been before used; but in the arrangement employed for operating them only one of them has been relieved from contact with the saslri'rame, according as the sash was to be either raised or lowered, the other remaining in contact with it, although not sufficiently close to interfere with the movement of the sash, yet nevertheless producing a certain amount of wear upon and injury to the same, whereas by my improvement it is entirely avoided, as both arms are relieved from contact with the sash, whether it is being raised or lowered, and by one and the same movement of the device varranged therefor.

I claim as new and desire to secure by Letters Patent- A sash-supporter consisting of the arms A, in combination with the lever-plaie K and springs E, when arranged together so that the said plate will act upon the said arms, substantiallyas described, and for the purpose specified.

The above speciiieation of my invention signed by me this 15th day ot December, 1866.

BURROUGHS BEACH.
