FASTENER SOCKET Application filed June 29,

This invention relates to separable fasteners adapted to removably secure together the partsof gloves, pocket-books, and the like,

H and relates particularly to the means for a permanently securing the socket in place in I the material. against detachment. Difficulty has been experienced with socketszof the type here involved in that the socket tends to work its way out of the material through the hole in the material through which thesocket ispassed. After a period, by reason of the enlargement of the hole due to the stretching of the material'under the strain and stress of use, the socket frequently becomes detached and its useful life ended.

My invention contemplates the provision of simple and efficient means to prevent such detachment of the socket even after repeated use. My invention further contemplates the provision of means such as prongs on the socket for firmly gripping and holding on to the leather or other material to which the socket is applied, to adequately fix the'socket to the material, and which means requires 5 no additional labor in assembling the parts but which is designed to be assembled into its operative position and simultaneously with the assembly of the socket parts with ease and rapidity.

My invention further contemplates the rovision of means for insuring the bending of the holding prongs and thereby more firm ly securing the parts in place.

The various objects of my invention will be clear from the description which follows, and from the drawing in which.

Fig. 1 is a cross-sectional view of my improved socket in its operative position in which it is secured in place, showing the rotation-preventing prongs imbedded in the material, and showing a cooperating stud for the socket in dash and dot lines. 7

Fig. 2 is a plan view of the combined anvil member and cap of the socket.

Fig. 3 is a partial cross-sectional and par tial elevational view of a modified form of my invention, showing the closed central por- 5 plied to comparatively thin material, where- ,member, prongs being provided 011 the lat- 1932. Serial No. 619,893.

by the prongs inserted into the material become bent out of their initial positions, being illustrated as being bent inwardly.

Fig. 5 is a similar viewof the same showing the prongs as bent outwardly.

' Fig. 6 is a similar View of a modified form of my invention, particularly showing the means for insuring the bending of the prongs, which as illustrated, are bent inwardly.

Fig. 7 is a similar view of the same, showing the prongs as bent outwardly instead of inwardly.

Fig. 8 is a plan view of a modified form I of the anvil and capmember, showing the upstanding prongs and the resilient rim on the member, the teeth of Fig. 2 being omitted.

In that practical embodiment of my invention which Ihave illustrated by way of example, my improved socket is preferably made of two pieces. One piece takes the form of a combined cap and anvil member, and the other takes the form of a flanged eyelet comprising the socket member. The unflanged or eyelet end of the socket member is forced into the interior of the anvil memher to hold the members together with the material compressed between the flange of V the socket member and the rim of the anvil ter member for the purposes above-mentioned.

As is well known,andas is shown in the patent to Lues Beiter for glove fastener, dated March 2nd,- 1920, No. 1,332,754, the flange of the socket member is usually arranged on one face of the material, and the eyelet portion of the socket member passed through a hole in the material. The anvil member is arranged on the other side or face of the material and the members pressed together in the direction of their axes to attach the members together and to the material, part of the eyelet portion being spread 95 and distorted by the anvil member to serve as a clinch joint for the members.

Referring now to Figs. 1 and 2, I have there illustrated a combined anvil and cap member- 10, the lowermost portion of which serves as 10 a socket cap. A rim as 11 is bent upwardly and inwardly from the cap portion. As shown, the rim is divided by aser'es of preferably radial slits 31 into a plurality of teeth 12 extending toward, but terminatin outwardly of, the central opening 13 in the cap portion. The rim 11 is suiiiciently spaced from the cap portion to provide an annular space 14 therebetween for the receptionand distortion of the lowermost portion 15 of the socket member 16, in a manner customary in the art. Certain of said teeth, however, are

bent upwardly and bevelled at their outer ends as 17, and pointed to provide the upstanding prongs 18. As shown, three of said prongs in spaced relation to each other are provided though it will be understood that as many prongs as may be desired may be so bent from the teeth 12.

The socketmember 16 comprises theliange 19 adapted to rest againstthe surface 20 of the piece of material 21, which may be leather, fabric or the lilro. The eyelet portion 15 of the socket member is first passed through the opening 22 of the material 211, thereby coming in contact with the upper surface of the anvil portion of the cap 10, after the anvil member and the socket member have been ranged on opposite sides of the material. A i;- ial pressure of said members toward each other thereby causes the eyelet portion to follow the curve of he anvil portion and to spread outwardly. At the same time, the prongs 18 are forced through the material 21 and therebv not only prevent rotation of thevthus assembled socket relatively tov the material, but further prevent enlargement of the hole 2'2 under the stress put upon the socket, when the cooperating stud 23is inserted therein and withdrawn. It will run ders tood that the socket is provided with the usual head 24: cooperating with thestud 28 to provide the required snapping engagement I and disengagement therebetween.

, vunderstood that said opening may-be omit so;

It will further be seen that the prongs 18 by their bracing action prevent stretching as illustrated in the remaining Referringfnow tol ig. 3, I have shown an imperforate combined cap and anvil-member 25 the inte ral central portion 26 of the can 7 V D l l.

part of the anvil member concealing the open ing in the socket member. 7

ll be As shown in Fig. 4E, owing to the use of com paratively thin material 27.,the prongs 1n strike the flange 19 of the socketwhen the parts are forced together during the assembly operation, causing the prongs to bend out of their initial positions. Unless thepr'on gs are given predetermined bias inwardly or outwardly, as is unnecessary since it is immaterial in most cases in which direction the prongs are bent, said prongs may bend'either deflection of the prongs so that said'prongs are-firmly imbedded n the material without penetrating the socket flange.

As has been indicated, the combined anvil and cap member may be made with a central hole as 13 therein, if desired, or imperforate and closed as at 26. It will be understood that if desired, the teeth-formin g slits or slots 81 in the rim of the anvil member may be omitted, and that only such slits made in pairs as to permit the bending up of the prongs 18, as shown in Fig. 8.

it will be seen that l have provided a simpleand efficient two-piece socket adapted to be firmly secured to a piece of material without danger of working therethrough and becoming detached therefrom, and that I have provided a socket well adapted to meet the severe requirements of practicaluse.

While I have shown and described certain specific embodiments of mv nvention, 1 do not wish to be understood as limiting myself thereto,.butdes1re to claim my invention as broadly asmay be permitted by the state of the prior art and the scope of the appended claims. 7
