JANES, OF WATERBURY, GONNECTICUT, ASSIGNOB TO SCOVILL MANU- FACTURING COMPANY, OF WATERBURY, CONNECTICUT, A CORPORATION OF CONNECTICUT SEPARABLE FASTENER Application filed November 19, 1930. Serial No. 496,695.

The object of this invention is to provide a resilient socket member of a snap fastener couple, with a collet encircling the spring elements in such way as to shield these elements against destruction of the snap action in the event of the article on which the socket is used being dropped, as on a floor, and stepped on, and whichwill take anyunusual blow,

and which also will protect the socket when the flange, to impart resilience to the socket collet.

member, and having a collet encircling and closed about the flange in such way as to permit resilient action in connecting the socket with a complemental stud member and disconnecting it therefrom, as I will proceed now to explain more fully and finally claim.

In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a top plan view; Fig. 2 is a bottom plan view, and Fig. 3 is a vertical section of the spring member of the socket. Fig. i is a top plan view; Fig. 5 is a bottom plan view, and Fig. 6 is a vertical cross section of the Fig. 7 is a vertical section of the spring element and collet assembled. Fig. 8 is a top plan view; Fig. 9 is a bottom plan view, and Fig. 10 is a vertical section of a cap for attaching the colleted spring element to an object and at the same time presenting a finish to the attached parts. Fig. 11 is a vertical section of the parts attached to a piece of material.

The spring element, shown detached in Figs. 1, 2 and 3, may be of any usual or approved construction, in which there is a barrel 1, terminating in a laterally projecting flange 2, the barrel being slitted partway of its length, as at 3, and these slits extending entirely through the flange, as indicated at i, so as to impart resilience to the device.

The juncture of the barrel and flange has an oifstanding head 5 which forms a constricted spring neck adapted to engage the complemental portion of the stud member (not shown) of the snap fastener couple, which stud member may be of any usual or approved construction.

The collet is composed of a top portion 6 provided with a hole 7 of a diameter larger than that of the barrel 1 of the spring element and also is provided with a circumferential flange 8. I

As shown in Fig. 7, the collet when applied to the flange 2 encircles said flange, and its top 6 and flange 8 are closed about the said flange 2 above and below, respectively, in such manner as to be entirely free from the bead 5. Thus the collet is arranged in floating engagement with the flange 2 and allows suflicient space for the expansion of the spring element in the act of connecting and disconnecting the stud member.

The thus colleted spring element is applied to an article, indicated by the part designated 9, Fig. 11, by inserting the barrel through the article and then closing the cap 10 over the barrel and mushrooming said barrel so as to afford a secure connection of the cap with the barrel.

This cap 10 may be of any approved construction, but the preferred construction, as shown in Figs. 8, 9 and 10, has the closed head 11 and the inturned slitted back 12, which slitted back engages the barrel'above the bead 5. I

When the parts are assembled as shown in Fig. 11, the collet takes up any strains placed upon the socket and thus prevents distortion. The collet, furthermore, in the case of any lateral pull or strain on the socket in coupling it with the complemental stud member, supports the socket member and thus prevents the undue pulling apart of the spring portions of the socket and so obviates the distorting and spoiling for future use of the said socket.

The collet. furthermore, when closed around the flange of the socket, acts as a shield which prevents the impairment or deluu 7 especially to the laundry wringer. Moreover,

' by the closed-in flange of the collet instead o of the socket and extendinginto close proxby this arrangement, any unusual blow or pressure upon the socket Wlll be taken up ofby the resilient member itself.

I am aware that it is old toprovide a collet on a socket member by means independent of the stud-engaging springs; and I am also aware that it is old to apply a collet to the turned-out edges of the spring socket, the application of the collet serving to turn out and clinch such edges; and. I am also aware that it is old to provide a spring socket memher having a lateral flange to which is applied a binding ring having a lower flange fitted beneath the oflset portion oi the flange of the socket and lying approximately flush with the surface of the socket flange and its stud-engaging portion, from which construc tion my socket and collet difl'er in that the top portion of the collet overlying the flange of the socket extends into close relation to the barrel of the socket and overlies the bead thereof while ,the lower portion of the collet underlies the flange and extends well below the bead; and I am also aware that it is old to apply a binder to a spring socket by placing the open end of the binder on the bottom ofthe lateral flange of the socket and then placing a ring above such flange and closing down the flange of the binder upon such ring, thus exposing the stud-engaging element of the socket to potential danger from blows instead of protecting it as in my construction.
