SNAP FASTENER Filed April 28, 1932 INVENTOR BY I Patented Nov. 1, 1932 JOSEPH W. DEWS, OF WATER/BURY, CONNECTICUT, ASSIGNOR TO SCOVILL MANUFACTUR- ING COMPANY, OF WATERBURY, CONNECTICUT, A CORPORATION OF CONNECTICUT SNAP FASTENER Application filed April 28, 1932. Serial No. 607,964.

This invention relates to an improved snap fastener socket element of more or less general application but of a form particularly adapted to be adjustably secured to the end of a strap and serve as means whereby the strap may be detachably connected with a strap provided with a complementary stud element.

It is'an object of the invention to provide a fastener element of the above-described character which shall be of relatively simple construction and correspondingly inexpensive and at the same time reliable and durable.

In the accompanying drawing illustrating the preferred form of the invention Figure 1 is a face view of the end portion of a strap having a socket element embodying the invention applied thereto.

Fig. 2 is a longitudinal sectional view of the strap and socket illustrated in Fig. 1, a complementary stud element in engagement with the socket element being represented in broken lines.

Fig. 3 is a side view of a strap endprovided with a stud adapted for engagement with,

the socket.

' Fig. 4 is a face View of a socket element embodying the invention, the same being represented as having been removed from the strap.

Fig. 5 is a reverse view of the socket element illustrated in Fig. 4.

Fig. 6 is a transverse sectional view through the socket element illustrated in Fig. 5, the section being taken along the line 66 and viewed in the direction indicated by the arrows.

Fig. 7 is a longitudinal sectional view of a socket element embodying the invention prior to the assembling of the body portion with the stud-engaging wire, the wire-engaging prongs being indicated as having been struck up from the material of which the socket is made but not yet bent around the wire.

Fig. 8 is a plan view of the stud-engaging wire of the socket element.

Fig. 9 is an edge view of the same.

In the form of the invention herein'disclosed the socket element comprises a body portion consisting of a plate of sheet-metal 20 having an opening or perforation 21 therein of a form'and size approximately equal to that of the stud with which the socket element is intended to be used.

Lying along the under side of the body portion of the socket element is a piece of bent wire 22 having curved resilient portions 23 lying just within and approximately following opposite portions of the opening 21. The wire 22 also has an attaching portion 24 lying against the under surface. of the plate 20 including parts which are preferably closely adjacent a pair of inturned strengthening ribs 25, and the wire may be firmly secured in position by means of aplurality of lugs 26 which may be struck up from the material of the plate and bent around the attaching portion '24 on the wire,- whereby thewire may be firmly clamped between the lugs and the ribs.

As herein disclosed the socket element is of atype adapted to be adjustably secured to a flexible strap and to that end isprovided With a pair of slots 27 through which the straps 28 may "be threaded as indicated in Figs. 1 and 2. 'If desired, one or more spurs 29 may be struck up from one of the margins of either or both of the slots 27 as a means of securely holding the socket member in any desired position of adjustment along the strap. 7

A stud80 secured to a complementary strap end3l may be snapped into engagement with the socket by thrusting its head between the stud-engaging elements 23 of the wire, after which the wire will resiliently snap into an engaging relationwith the neck portion 32 of the stud 'whilethe head will be firmly held by the walls of the socket element surrounding the opening'21.

It will be apparent that any lateral pull of one of the'two stranelements 28, 31 with respect to the other will be resisted by direct engagement between the stud 30 and the walls surrounding the opening 21 in the body portion of the socket element, whereas the studmay be readily separated from the socket element by pulling the straps away from each other so as to impart an axial pull between the stud and the socket element, thus causing the resilient portions 28 of the studengaging wire to be spread sufficiently to release the socket.

The wire element of the socket member illustrated in Figs. 8 and 9 may be readily assembled with the body portion QO-by placing the endportions between the lugs 26: when in their outwardly-turned positions, as indicated in Fig. 7 and the ribs 25, after which the lugs may be rolled to their wire-retaining positions as indicated in Fig. 6, thus clamping the end portions of the wire between the lugs and the ribs.

The invention is not intended to be limited to the specific form herein selected for pur- L poses of illustration, but should be regarded;

as covering modifications and variations thereof within the scope of the appended claims.

' lVhat is claimed is:

I. A snap fastener socket comprising a plate having a perforation therein of the approximate size and form of a complementary snap fastener stud with which the socket is to i be used, and a piece of resilient wire having cu-rved portions approximately following and lying just within the oppositely-disposedportions ofthe perforation at one surface of the plate to resiliently engage the neck of an in- 3 serted stud, the wire having also an approximately rectangular attaching portion lying against the surface of the part of the plate surrounding the perforation and; the plate having a. plurality of attaching lugs struck up therefrom and rolled over the adjacent portions of the wire, the lugs being so positioned as to project upwardly-from the plate at the four inner corners of the attaching portion of the wire.

1o 2.. A snap fastener socket, as defined by claim 1, of which the plate has a pair of watifiening ribs turned downwardly along 0pjsite margins, the attaching portion of the resilient'wire being of a form: such as to have 4.) oppositely-disposed portions parallel to and closely adjacent said ribs, and the attaching lugs being so disposed as to clamp the adjacent portions of the wire between the lugs and said ribs. 3. A snap fastener socket, as defined by claim 1, of which the plate has a pair of slots at opposite sides of its stud-receiving perforation to: receive a strap'to which it may be adjustably secured. V

p In witness whereof, I have hereunto signed my name. a
