CHARLES ROBINSON, OE TORONTO, ONTARIO, CANADA.

BUTTON AND STUD.

SPECIFICATION forming part of Letters Patent No. 241,722, dated May 17, 1881.

Application filed May 31, 1880. (Model.)

, To all whom it may concern Be it known that 1, CHARLES ROBINSON, of the city of Toronto, in the county of York, in the Prdvince of Ontario, Canada, jeweler, have invented certain new and useful Improvements in Shirt Studs and Buttons, of which the following is a specification.

This invention relates more particularly to an improved fastening for shirt and other studs and buttons; and it consists in the combination, with a fixed prong, which extends first downwardly and then outwardly from the center of the bottom of the stud, of a similarlyshaped prong, which is movable'around the other prong for the purpose of fastening the stud to and detaching it rom the shirt or other garment.

Referring to the accompanying drawings, Figures 1 and 2 are perspective views of a stud embodying my improvements. a section, and Figs. 4 and 5 bottom plans of the same.

A is the stud, to the. under side of which is attached a fixed prong, B. This prong extends downwardly and then outwardly from the center of the stud, and on it is mounted the movable prong B, of substantially the same shape.

The prong B is provided with a socket or sleeve, 1), which is fitted on the upright portion of the stationary prong and retained in position by a shoulder, b.

, Both prongs are of substantially the same shape, and when placed in the position shown in Figs. 1, 3, and 4. form a retaining crossbar, which effectually holds the stud in place. In this position the movable prong is held, by means of the spring-arm B and the cam-projection (J, from displacement, while to prevent the prong being turned too far, a stop-block, D, is provided, against which the armB bears.

Figs. 2 and 5 show the position of the pron gs when fitting the stud into and detaching it from place. Here the prongs are brought close together, forming but one bar, which can readily be passed into and out of a small opening in the shirt or other garment; and,if desired,

. the ends of the prongs can be pointed and be made to effect their own entrance by pressure.

The fixed prong B and the movable prong B, provided with the spring-arm B made in Fig.3is

viz., it retains the sleeve 11 on the upright portion of the fixed wire B and limits the revolution of the movable wire prong B in one direction by acting as a stop, the movement of the movable wire prong in the opposite direction being limited bythe cam-projection O and stop D.

I am aware that Letters Patent for a button-fastening have been granted L. Goodwin, dated June 29, 1858, No. 20,707, and I therefore lay no claim to such invention, which differs from my construction in several important particulars, among which the following may be ennmerated,viz: The prongs of Goodwin are not formed of wire; nor are the movable prong and its revolving arm made in one piece, nor provided with a sleeve secured to the movable prong and adapted to rotate on the fixed prong; nor is a shoulder employed by Goodwin retaining the sleeve in place, and also acting as a stop to limit the movement in one direction of the movable prong.

My construction is different, simpler, and cheaper than the invention disclaimed, and the parts more readily put together.

I claim as new and desire to secure by Letters Patent The combination, with the stud-head A, having the projections O D on its lower face, of the fixed angular wire prong B, provided with the shoulder and stop I), and movable angular wire prong B, provided with the wire springarms B formed therewith, and sleeve 1), secured to the movable arm and fitting around the upright part of the stationary wire prong, substantially as described, and for the purpose set forth.

O. ROBINSON.
