' Application and February 26, 1925. Serial No. 11,693.

'This invention aims to provide an improved separable fastener. In the drawings, which ferred embodiments of my invention Figure 1 is a front elevation of the fastener; v

Fig. 2 is a section on the line 22 of Fig.1; j Fig. 3 is a rear elevation of the socket; Fig. 4 is an elevational view of the socket casing before attachment to a support; Fig. 5 is a side elevation of the socketcasing shown in Fig. 4;

' Fig. 6 is a front elevation of the second '15- form of my invention, showing a different form of prong-receiving part from that shown in the first form;

Fig. 7 is a section on theline 7- -7 of Fig.

.6; and

Fig. 8 is a section on the line 8'-8 of Fig. {3,

illustrating the form that the carrying medium assumes when a stud has been engaged with the socket and showing the freedom of the resilient walls of the socket.

Referring to the drawings, 1 haveshown a simple, durable and inexpensive type of snap fastener and two simple forms of prong-receiving clench plates for securing the socket casing to'its support without cutting a hole in the support except for the attaching prongs.

The fastener illustrated in Figs. 1 through 5 includes a stud member having a head 1, a neck 2 and a base portion 3 secured to a flexible su port 4 by a tubular rivet 5 upset within the lead 1 of the stud in the usual manner. The fastener also includes a socket having a casing secured to a flexible support as more fully hereinafter described.

The socket casing, as illustrated, is pressed from a single piece of metal and presents a peripheral cylindrical wall 6, a second cylindrical wall 7' within the peripheral wall 6, and a third cylindrical wall 8 within the 45, second wall. All of the walls are parallel with and spaced away from each other, as illustrated. The walls 6 and 7 are connected by a web 9 at one end of the casing and the walls 7 and 8 are connected by a web 10 at the opposite end of the casing, as illustrated in Fig. 2. At the free end of the third wall 8', I have provided a reversely bent portion 11, which surrounds a stud-receiving aperture 12 and forms means for engagement with the illustrate two nec k of the-stud. The walls 7 and 8 are made resilient to permit passage of the head of the stud through the aperture 12 by dividing them 1nto resilient fingers'by a plurality of slots terminating in the web 9, as illustrated in Flgs. 2,3 and 4. These fingers are adapted to expand and contract to permit the head of the stud to pass through the stud-receiving aperture and the expansion and contraction of the fingers is distributed over their entire length and not concentrated at any one point. This construction, therefore,'is highly desirablebecause the socket is more duraing set is greatly reduced. While the socket casing may be securedto its flexible support 14 in any suitable manner, I prefer to secure it thereto by a clench plate or cap 15 and a plurality of prongs16. The prongs 16 extend from the peripheral wall 6 of the casing through the support 14 where they are clenched. into' engagement with the cap 15 as illustrated.

Thus the casing is secured to the support 14 without weakening the fabric, as is the case when a central attaching rivet is passed through a hole in the fabric. The fabric 14 is also maintained in substantially the same plane throughout thereby avoiding unnecessary stretching thereof. As illustrated in Figs. 2, 7 and 8, the fabric 14 is stretched loosely over the resilient portions of the socket, and the cap member is spaced away from the fingers at least the thickness of the cloth, so that there is no gripping of the. fabric above the fingers. Thus the fingers may contract and expand without interference from the support 14. The cap memher is provided with a central dome 17 to provide a space into which the fabric may be pressed when the stud and socket are engaged, as illustrated in Fig. 2.

Figs. 6, 7 and 8 illustrate the second form of cap member 18 in combination with a socket substantially asshown and described in the first preferred embodiment of my inble and the possibility ofthe fingers becom- .sented by the socket casing, cure the socket casing to the support 14;

and upsetting the attaching pr A there;

ferred embodiments of myrinvention, it will be understood .thatI have done so for purposes of clarification only, in invention be-' best definedjin the appen ed claims. .laims: 1 v

' said walls and the said cap part presenting surfaces toward: the carryin medium whichermit the carrying medium etween them to 'e in substantially the same plane as the remainder of the carrlying medium.

2. A fastener soc et comprising, in combination, a oneiece socket casing located at one I side of a fiexi le fabric and presenting beyond the face of the fabric a continuous outer peripheral wall, a second wall within the peripheral wall and a third wall within the second wall, all of said walls being parallel and inthe same plane, a luralit of slits extending through thesecon and thirdwallstoprovideresiliency,

and a plurality of rounded reversely bent portions resentedby said third wall to provide for su stantial engagement with the neck of a stud, said reversely bent portions ,expansible with the second and third walls to permit smooth passage of the head of the stud into and out of engagement with the socket, and

a means integral with the outer peripheral wall for cooperation with means located at the 0pposite face of the fabric thereby to secure the casing to the flexible fabric.

3. A fastener socket including a casing lo cated at one side of a flexible support and having a peripheral wall presenting a plurality of attaching prongs for cooperation with an attaching part located on the opposite'side of the flexible support for securing said casing to the support in such a manner that the support remains imperforate except where pierced by said prongs, a plurality of resilient stud-receiving fingers bent parallel with the peri heral wall, first in one direction and then in t e opposite direction and terminatin about a stud-receiving a erture, the parallel portions of each of said igers being spaced relative to each other and relative to the soc the peripheral wall permit free lateral flexing of said fingers over their entire lengths thereby to permit the head of a stud'to ass between the free ends of said fingers, an reduce to a minimum the gers becoming set;
