BUTTON.

SPECIFICATION forming part of Letters Patent No. 394,132, dated December 4, 1888.

Application filed September 12, 1888. Serial No. 285,224. (No model To aZZ whom, it may concern.-

Be it known that I, (HARLES PRENTICE, of Putnan'nin the county of Windham and State of (onnectim1t, have invented certain n cw and useful Improvements in Buttons; and I do hereby declare the tollo wing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in buttons, and more particularly to buttons intended to fasten carriage-curtains, detachable portions of leather harness, and button shoes.

The object isto provide a button over which the lnitton-hole may be readily passed without unduly stretching it, and which may be then adjusted to lock the part in which the button-hole is formed thereon and be automatically held in locked adjustment.

A further object is to provide a button which shall. be simple, durable, and quite inexpensive.

\Vith these ends in view my invention consists in certain features of construction and combinations ot' parts, as will be hereinafter described, and )ointed out in the claims.

In the accompanying drawings, Figure 1 represents a curtain locked to a support by thebutton. Fig. Qrepresents the curtain partially adjusted over the button, showing the position of the button to receive the curtain. Fig. 3 represents the button in side elevation, and Fig. 4- represents the several parts of the button in detail.

A represents a port ion of anysuitable frame or support to which it may be desired to fasten a curtain strap or flap of any description; and for the purpose of showing the use of the button a curtain, B, is herein shown as the part to be secured to the frame or supturning head portion E preferably consists of a spring-wire loop, the ends of which are turned to form eyes c, which loosely embrace the reduced portion (I of the standard and permit the loop E to be swung at right angles to the axis of the standard.

The branches of the spring-wire loop or head E have a tendency to sprcz'ul apart t'arther than the distance they occupy when in position on the stamlard, and the stamlard is provided with shoulders 11 (I at the extremities of the reduced portion (I, which serve to retain the branches in their partially-closed adjustment, and hence produce friction between the eyes e oi the loop and the shoulders (1. (1", which friction serves to retain the loop in a position in which it may be turned.

\Vhere the standard or shank l) is to be secured to a t'rame, as shown in the drawings, I find it desirable to employ a screw to form the reduced portion d of the shank, and the enlarged portion l) is t'm'med by a cylindrical. cap or short tube, through which the screw (1 cxtcmls into the frame, 1 he port ion 1) being cramped between the lower or inner branch of the loops E and the frame, and the top of the portion D and the head of the screw forming the shoulders d (7 This construction has the advantage of allowing the spriug-tension of the branches to be increased or diminished by turning the screw (1 in or out, and hence regulating the readiness with which the loop may be turned. \Yhen the curtain is to be fastened, the loop or head E is turned into position, (shown in Fig. 2,) so as to correspond to the direction of the slit portion c of the button-hole. The curtain is then pressed over the button, the standard or shank passing through the portion c of the button-hole and the loop E through the slit (1, and when in position the loop or head E is turned to the right or left and the curtain is locked in position.

The spring-tension ot' the branches of the loop 1 serves to hold the loop in position until it is positively swung again into position to admit of the removal ot'the curtain.

It will be observed that there will be little or no strain upon the button-hole, because of the very narrow portion of the button passing through the narrow portion of the button hole.

It will also be seen that the abovedescribed button might be employed to fasten a part which was essentially rigid about the buttonhole by simply making the button-hole large enough to admit the button when turned into the position shown in Fig. 2.

It is evident that slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my invention; hence I do not wish to limit myself strictly to the construction herein shown and described; but,

'Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The described button, consisting of a standard or shank portion and a swing springhead seated on the standard or shank portion, the said spring-head being held in its swinging adjustment by its own tension, substantially as set forth.

2. The herein-described button, consisting of the standard or shank, and the spring loop 1 and a base portion surrounding the screw,

and a swing spring-wire loop or head having its branches compressed between the head of the screw and the said base portion, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing. witnesses.

CHARLES PRENTICE.
