3 Claims. (Cl. ,M -218)` My invention aims to provide improvements in snap fastener sockets.

In the drawing which illustrates a preferred embodiment of my invention:-

' l Figure 1 is a section through a snap fastener 1c carrying medium engaging surface; and

Fig. 3 is a plan View of the socket showing that face from which the stud enters.

Referring now to the specific embodiment of my invention, as illustrated by the annexed drawing, I have shown a socket structure which is particularly adapted for use on wearing apparel and other articles adapted to be laundered. The two most important objects of my invention are to provide a socket having a relatively small stud-receiving aperture with a relatively large support-engaging surface and to provide within the socket casing a structure which will prevent crushing of the casing.

The particular socket illustrated includes a one-piece sheet metal casing part having a rear face 1, a front face 2 spaced from the rear face 1 and connected at its outer periphery by a wall 3, as best illustrated in Figure l. The front face has a stud-receiving aperture 4 of small diameter compared to the diameter of the casing and is intersected by a split ring spring 5, as best illustrated in Figs. 1 and 3. Between the spring 5 and the wall 3 (Fig. l) I have provided an integral double wall 6 extending from the rear face 1 toward and against the inner surface of the front face 2. This wall 6 is spaced inwardly from the peripheral wall 3 thereby to provide means for properly positioning the spring 5 with relation to the aperture 4. This wall also prevents accidental crushing of the casing during the laundering process of the article to which it is attached or at any other time.

By usingi a double wall 6 and an outer peripheral Wall 3, spaced therefrom laterally, I provide an additional area 7, outside of the surface 1 heretofore provided, thereby to increase the area of the surface 1 which may come in contact with the material to which the socket is to be attached.

The particular socket shown is secured to a flexible carrying medium 8 (Fig. 1) by a rivet 9 carried by a suitable cap member 10. 'Ihe rivet 9 extends through the carrying medium 8, through a hole 11 in the surface 1 of the socket surface of the back face 1.

Any suitable stud member may be used according to the particular formation of the casing and the spring used in conjunction therewith. The stud installation illustrated includes a stud member 12 secured to one side of a carrying me- @o dium 13. by means of a suitable attaching member 14, the base of which is shown in Figure 1.

My improved socket is particularly desirable because it will withstand av relatively great amount of crushing stress without injury. Furthermore, because of the additional fabricengaging surface provided by the structure described above, a relatively large cap 10 may be used in combination with the casing thereby gripping a large enough area of the carrying 1o medium 8 so that the carrying medium will not tear loose from between the cap and the socket when lateral stresses are exerted thereon.

While I have illustrated and described a preferred embodiment of my invention I do not wish to be limited thereby because the scope of my invention is best defined by the following claims:

1. A snap fastener socket comprising a hollow stud-receiving casing part formed from sheet s@ metal and having a stud-receiving aperture at one side thereof, a stud-engaging spring located in said casing and intersecting said stud-receiving aperture, said casing part having a continuous one-piece front face surrounding the stud- 8,5r receiving aperture, a back face spaced therefrom,

a peripheral wall connecting the two faces .of the casing and means located inwardly from said peripheral wall and entirely between the faces to support said faces and prevent accidental crushing of the casing part thereby to maintain the proper spacing for operation of said spring. j

2. A snap fastener socket comprising a hollow stud-receiving casing part formed from sheet metal and having a front face and a back face spaced from each other, a stud-receiving aperture in the front face, a spring located in said casing and intersecting said stud-receiving aperture, a wall extending from one of said faces toward and into engagement with the other face and surrounding said spring, a return bend oi'v said wall extending back to the face with which it is integral, a portion ofsaid face extending outwardly from the return bend of said wall in the plane of the other face portion with which said wall is integral to increase the area of said face and a peripheral wall portion connecting said outwardly extending portion and the other face at the edge of said casing.

3. A snap fastener socket comprising a hollow stud-receiving casing part formed from sheet metal and having a rigid frontface 2 provided with a stud-receiving aperture 4, aback face 1,

`a. peripheral wall 3 connectingV said front and back faces, a double Wall 6 extending from ysaid rear face toward and into engagement with said front face andbeing located inwardly from the as y' 1
