ERNEST D. SIMONS, OF WATERBURY, CONNECTICUT, ASSIGNOR TO SCOVILL WATERBURY, CONNECTICUT, A COR- MANUFACTURING COMPANY, OF PORATION OF CONNECTICUT.

SNAPT-FASTENER;

SPECIFICATION forming part of Letters Application filed August 12, 1903.

T at whmn it may concern.-

Be it known that I, ERNEST D. SIMoNs, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a certainnew and useful Improvement in Snap-Fasteners, of which the following is a full, clear, and exact description.

The object of this invention is to provide a 1 simple, efficient, and durable socket member for snap-fasteners for use on gloves and garme'nts generally and for other purposes, and

more especially a spring socket member to cooperate with a solid or unyielding stud.

In some socketmembers heretofore devisedthe spring action has been obtained by radially or otherwise slitting their mouths and in some instances applying a restraining device to prevent or lessen the undue yielding of the mouths for the entrance and exit of the stud, which undue yielding has a tendency to set the socket and render it ineffective to hold the stud in engagement. In forming the socket its stud-receiving member has been constricted next the base-flange and slit portion to make a contracted mouth of less diameter than the larger diameter of the stud, which yields for the entrance and exit of the stud and closes again behind it. It is this operation that tends to impair or destroy the resilience of the socket when unduly carried on, and my invention is designed to counteract such tendency.-

The invention consists of a snap-fastener having a spring-socket and a solid, rigid, or unyielding ring applied externally to the mouth of the socket and adapted to prevent the undue expansion of such mouth for the passage of the stud into and out of said socket, as I will proceed now more particularly to set forth and claim.

In the accompanying drawings, illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1' is a vertical section of a snap-fastener applied 45 and closed and containing the present improvement. Fig. 2 is a perspective view of the socket. Fig. 3 is a top plan View of the socket. 'Fig. L is a perspective view of the Patent No. 757,237, dated April 12, 1904.

unyielding ring. Fig. 5 is a vertical section of the socket detached. Fig. 6 is a vertical section of amodified socket detached, showing its dome shouldered to insure against the loss stud-receiving member or dome 2 rising therefrom, said dome being constricted to form the mouth 3 of relatively smaller diameter than the dome. A number of radial slits 4 are present in the flange and extend into the dome, so as to render the mouth of the socket yielding or, in other words, to produce a springsocket, said slits permitting the socket to yield forthe entrance andexit of the stud 5. The stud, as here shown, is solid or unresilient; but it may be of other construction. In order to limit the play of the socket in applying and removing the stud, I place a ring 6 of solid or rigid constructionthat is to say, an unyielding ringupon the flange next the constricted portion, so that it is impossible for the socket to be stretched or sprung apart unduly or beyond its elastic limit, and thus the integrity of the spring-socket is permanently insured. This ring isflat and may be made of very thin metal, so as to occupy no appreciable space and aflord no appreciable protuberance in applyingthe socket to material.

As seen in Fig. 1, ahole is made in the material 7 and a hole 8 in the top of the dome, and the dome being inserted in the hole in the material a cover or cap is applied on the outside. The cap herein shown has an eyelet member 9 inclosed in a cover 10, and the eyelet member is adapted to engage the hole in the dome and to be upset therein in order to effect a permanent engagement of cap and socket and the consequent permanent application of the fastening to the materialor garment.

In order to insure against the loss of the ring in marketing andhandling the goods, the swell of the dome may be at its greatest diameter greater than the internal diameter of the ring, as in Figs. 1 to 5, or in case it be desired to hold the ring within strict limits and also prevent its escape the sides of the dome may be bulged out to form a shoulder 11 immediately above the ring, as shown in Figs. 6 and 7.

It is to be observed that the ring 6 has no function or utility as a means for fastening or securing the socket member to the material.

While I have herein shown a preferred means for securing the socket to an article, it is to be understood that the invention is not limited thereto, excepting in so far as the fastening means is independent of the unyielding ring.

What I claim is- 1. A spring-socket member, for snap-fasteners, having a base-flange, a stud-receiving dome rising therefrom and constricted to form a mouth, said dome adapted to be engaged by an independent fastening cooperating with the base-flange to secure the socket member to an article, and an unyielding ring externally surrounding said mouth and resting upon said base-flange, and operating wholly independently of the fastening solely as a means to prevent overcoming the elastic limit of the socket.

2. A spring-socket member, for snap-fasteners, constricted about its mouth, and having a base-flange, and an unyielding thin, flat metal ring applied externally in the constricted portion and resting upon the base-flange, combined with means independent of the ring for securing the socket member to material.

3. A spring-socket member, for snap-fasteners, having a dome, a base-flange, a yielding mouth, an unyielding ring externally surrounding said mouth and resting upon the base-flange, and a shoulder on the dome above the ring, combined with means independent of the ring for securing the socket member to material.

4. A snap-fastener, having a socket member provided with a dome, a base-flange, acontracted mouth, and slits through the flange and mouth and extending into the dome, and an unyielding ring applied externally to the contracted mouth next the flange and dome and adapted to prevent the elastic limit of the socket from being overcome, combined with means independent of the ring for securing the socket member to material.

5. A snap-fastener, having a socket member provided with a dome, a base-flange, a contracted mouth, and slits through the flange and mouth and extending into the dome, and an unyielding ring applied externally to the contracted month next the flange and dome and adapted to prevent the elastic limit of the socket from being overcome, combined with a cap or cover adapted to engage the dome and secure the socket to an article independently of the ring.

In testimony whereof I have hereuntoset my hand this 7th day of August, A. D. 1903.
