FASTENER.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed January 16, 1905. Serial No. 241,175.

To all whom it may concern:

Be it known that I, GEORGE A. HoLMEs, a citizen of the United States, and a resident of Newton, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Fasteners, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to that class of fasteners consisting of a stud or button member and a socket or buttonhole member; and it consists in a stud or button member embodying certain new features of construction hereinafter shown and described.

Referring to the accompanying drawings, Figure 1 shows in section the two parts of my improved stud member as they are commercially sold. Fig. 2 shows in section the two parts of my improved stud member placed together with the material between them prior to being riveted together. Fig. 3 shows the same after the operation of riveting has taken place. Fig. 4zShOWS a plan of the birdcage or resilient stud, and Fig. 5 shows a side elevation of same. Fig. 6 shows in section a modification of my improved stud mem ber before assembling, and Fig. 7 shows the same complete.

As shown in the drawings, my improved stud member consists of the stud A and the dome-attaching eyelet B. The stud A has the struck-up bird-cage X, (shown by itself in Figs. 4 and 5,) the collet Y, and the convex attaching bottom plate Z.

The bird-cage X is preferably struck up, as usual, from a star-shaped piece of metal, the radiating arms thereof being of substantially uniform width from the center or point of juncture to their ends, as distinguished from having at their respective ends enlargements contacting with each other to prevent collapse.

The collet Y serves to connect, as shown, the ends of the arms of the bird-cage X and the periphery .2 of the convex bottom plate Z. In Figs. 6 and 7 I show a modification in which I use an integral combined collet and convex bottom plate W, which may serve the purpose of the two corresponding pieces shown in'Figs. 1, 2, and 3.

The dome-attaching eyelet B has the hollow dome b and the flange b, the dome 5 being of such diameter as to just pass easily ber.

through the opening 2 of the convex bottom plate, as shown in Fig. 2. When the two parts are placed together with the material between them, as shown in Fig. 2, and pressure applied in any suitable manner, the convex bottom plate Z, which also serves as a biting or clench-effecting part, is flattened, contracting the central opening a and biting into the dome 6 of the attaching-eyelet, as shown in Fig. 8, with the result that the cylindrical wall of dome or shank is indented and the two parts are firmly riveted together onto the material. The thickness of the material will determine the point at which the biting or indenting of the eyelet will occur. In this way an eyelet of uniform diameter will be useful for varying thickness of material within certain limits.

The purpose of having the attaching-eyelet closed over its top is that it may be rigid to form an effective support for the spring-arms of the bird-cage, this giving it the form of a dome. The dome 6 for this purpose fills the interior of the bird-cage sufficiently to preventits collapse by the withdrawal of the ends of the bird-cage from the collet when the stud member is snapped into a suitable socket mem- By this I mean that the diameter of the eyelet shank or dome must be sufiiciently large that it may rest in contact with each of the arms at their nearest points below their bulge or bow, and thereby preclude any radial play of the arms within the collet Y. The resilience is afforded entirely by the bulge or bow of the arms of the bird-cage, which give or change curvature under the stress of engaging or disengaging with a socket. Of course the eyelet-shank must be of sufficient length or height to extend into the bird-cage at least sufficiently far to occupy the space between the nearest points of the spring-arms b6l0\ the bulge.

Heretofore in making bird-cage or resilient stud members of the form shown resort has been had to various special devices in the manufacture to prevent this collapse, such as inserting a fixed dome or filler within the bird-cage and also by providing the ends of the spring-arms with circumferential ends or feet, which when inclosed in the collet meet and form a continuous flange at the base of the bird-cage. By the construction of my improved stud member I do away with the necessity of providing the bird-cage as sold with any internal support or collapse-preventing device, for during the process of manufacture a suitable pin can be inserted within the birdcage while it is being formed, and after the setting the dome of the attaching-eyelet performs this necessary function.

Asillustrated in Fig. 1, where the parts are shown before setting'or riveting upon the material, my improved fastener may be made and sold as a commercial article of manufacture. As such article of manufacture it is then in condition for use by manufacturers of gloves or other garments or articles, because it is all ready for attachment to the perforated material of a glove or other article by the mere use of a simple riveting or clenching tool or machine to effect a riveting or clenching pressure exerted between the flange or collet above the material and the attaching or collapse-preventing eyelet on the opposite side of the material or its flange.

What I claim as my invention is- 1. The stud member of a separable fastener. consisting of a spring-stud having centrallyjoined radiating spring-arms of substantially uniform width throughout their length, provided with a convex perforated attaching bottom plate, in combination with a stud attaching and supporting eyelet, all arranged and combined as and for the purposes substantially as set forth and described.

2. A stud member of a separable fastener consisting of a struck-up spring-stud having radiating arms of substantially uniform width throughout, provided with a perforated bottom plate, in combination with the material towhich the stud member is attached, and a stud attaching and supporting eyelet substantially filling the interior of said stud, said eyelet flanged at one end and closed at the other, and passed through from the side of said material opposite said stud,with the material between the flange of said attaching-eyelet, and the bottom plate, all arranged and combined substantially as and for the purposes as set forth and described.

3. In a stud member for a separable fastener, the combination with the material to which the stud member is attached, of a birdcage spring member, the centrally-united radiating spring-arms of which are of substantially uniform width throughout their length, and a collapse preventing eyelet having a flange below the material, the said stud member having secured to it a biting part engaging'and indenting the shank of said eyelet for holding the stud member firmly riveted upon the material to which the fastener is attached.

4. A stud member for a separable fastener,

comprising a spring bird-cage the centrallyunited radiating arms of which are of substantially uniform width throughout their length, combined with the material to which thestud member is attached, and a flanged attachingeyelet comprising a flange below the material and an integral shank, the wall of which extends upwardly into the interior of the birdcage sufliciently to prevent collapse of the spring-arms thereof.

5. As a commercial article of manufacture, a stud member of a separable fastener, ready for attachment and comprising in combination, a spring bird-cage consisting of centrally-united spring-arms of substantially uniform width, a combined attaching and collapse-preventing part adapted to be passed through an aperture in the material to which the fastener is attached and into said birdcage and there clenched by pressure, and a part provided on said bird-cage member adapted to cooperate with said attaching part to effect such clenching, substantially as shown and described.

6. In a stud member for a separable fastener as commercially sold, before application to the material to which the fastener may be applied, the combination of a spring birdcage comprising spring-arms of substantially uniform width and a clench-eflecting part rigid therewith, and a combined attaching and collapse-preventing eyelet adapted to be extended through an aperture in the material and there clenched or riveted to the spring member, said eyelet being of uniform diameter and suflicient length to extend into the bird-cage and support the arms thereof for varying thicknesses of material, substantially as shown and described.

7. The stud member of a separable fastener, consisting of a spring-stud having centrallyjoined radiating spring-arms of substantially uniform width throughout their length, provided with a convex perforated attaching bottom plate, in combination with a stud attaching and supporting eyelet, said eyelet being of uniform diameter and sufficient length to extend into the bird-cage and support the arms thereof for varying thicknesses of material, all arranged and combined as and for the purposes substantially as set forth and described.

In testimony whereof Ihave signed my name to this specification, in the presence of two subscribing witnesses, on this 14th day of January, A. D. 1905.

GEORGE A. HOLMES.
