G. JGHNSN FASTENER Filed June 14, 1924 FASTENER.

Application filed June This invention aims to provide an improved socket for a separable fastener.

In the drawings, which illustrate a preferred form of my invention Figure 1 is afront elevation of a preferred form of fastener;

Fig. 2 is a section on the line 22 of 1, being partly in elevation;

Fig. 3 is a front elevation of the preferred form of socket;

Fig. lis a longitudinal section, partly in elevation, through the socket showing the parts as they appear before the screwzis secured in place;

Fig. 5 is a rear elevation of the socket as shown in 4;

Fig. 6 is an enlarged side elevation of the completed socket;

Fig. 7 is a rear elevation of the socket as shown in Fig. 6; and

Fig. 8 is a detail section on the line 8-8 oi Fig. 7.

Referring to the drawings, 1 have shown, for illustrative purposes only, a stud 9 which may be secured to a flexible stud-carrying fabric 10 in any suitable manner. The stud may or may not be provided with means for locking the stud with the socket. I have, however, illustrated a stud like that shown in my co-pending application filed herewith, Serial No. 719,926, which resents a button 11 for operation of a locking member (not shown). @n the opposite side ot'the curtain from the button 11, l have provided a socketengaging contractible and expansible head 15.

The preferred form of socket includes a casing having a body part 17 presenting at its inner end a double wall portion 19 and a partition 20, which forms a separate recess 21 apart from the rest of the body part 17. This recess is formed by pressing the closed end of the body part 17 toward the front end thereof, thereby turning the wall of the body part 17 back within itself to form the double wall portion 19 and the partition 20.

The socket also presents an attaching screw 25, which is secured to the body portion 17 of the socket by first placing the hexagonal head 23 of the screw in the recess 21, then flattening the double wall portion 19 against the outer periphery of the head of the screw, thereby changing the double wall portion 19 from circular to non-circular, herein hexagonal cross-section to fit the head 23 of the screw. lhe overlying portion of the double 1324.

wall 19 then bent against the outer face of the head or the screw, thereby to hold the attaching screw 25 in fixed relation to the body part 1'7 of the socket.

At the front end of the body have provided a generally circular flange 27, against which are clenched the petal-like projections 29 presented by a front plate 31, thereby to secure the front plate and body part 17 together. 'lhese petal-likc projections 29 preferably bent over the edge of the flange 27 and then presses ii to the flange 27 provide interlocking engagement between the front plate 31 and the body part 17 portion 17, I

so that there can be no relative rotation bc- L tween the two parts of the casing, as best illustrated in Figs. 7 and 8.

The front plate 31 presents a stud-receiving aperture and a. plurality of tool-receiving slots 33 extending from the periphery of the studreceiving aperture. The front plate 31, as illustrated, is also preferably dished toward the stud-receiving aperture to facilitate entrance of the stud, and the inner edge thereor" is bent inwardly to form a curved annular wall 34: around the stud-receiving aperture to present smooth surface for engagement with the stud. The studrcceiving aperture and the tool-receiving slots are normally closed by a sealing disc 37' urged into normal position by a spring 39, thereby to exclude dust and dirt from the casing.

The socket, as illustrated, is of the flush type and there fore the body part 17 must be countersunk in the support to which the socket is to be attached, which in this instance, as shown, is the body l0 of an automobile provided with a socket-receiving recess.

I Attachment of the socket is efi'ected by insorting the blade of a screw-driver or other suitable tool in two of the tool-receiving slots 33 and rotating the tool in a clockwise direction. Thus rotation is imparted to the casing and to the attaching screw 25, which screws into the body 40 of the car and draws the body part 17 into the socket-receiving recess until the flange, located at the front oi the casing, is seated against the side of the car, as best illustrated in Fig. 2.

l Vhile l have shown and described a preferred tor-in of one embodiment of my in'ven tion,it will be understood'that changes involving omission, alteration, substitution and reversal of parts, and even changes in the mode of operation, may be made without departing from/the scope of my invention, which is best defined in the following claims.

Claims:

1. A fastener socket including a tubular casing, a partition between the ends of said casing, means at one side of said partition for receiving a coo crating stud and a recess at the other side 0 said partition surrounded by a wall crimped over the head of an attaching member located in said recess to prevent relative rotation between the casing and attaching member.

2. A separable fastener element including a casing presenting a closed end, means providing a pocket beyond said closed end and attaching means having a head and a shank, the head of said attaching means being held rigidly in said pocket.

3. A flush type socket for a separable fastener including-a hollow casing presenting at its outer end an aperture for reception of the head of a cooperating stud, said casing presenting-a recess at its inner end,-said recess being closed toward the outer end of the casing ,and open toward the inner end of the casing, an attaching screw having a head entered in said recess and engaged with said closed end, and said casing presenting inwardly crimped portions beneath said-head at the extreme inner end of said casing and adjacent to the open end of said recess for holding said screw in said recess.

4. A flush type of socket for a separable fastener including a casing presenting a hollow body part having a closed end, a pocket beyond said closed end for reception of the head of an attaching screw and a double wall surrounding said pocket, said double wall 6. A flush type socket for a separable fastenor, including a hollow casing presenting a transverse partition between its ends, a double wall surrounding a recess beyond said partition and an attaching screw seated against said partition and held thereagainst by said double wall.

7. A; flush type fastener element comprising a body portion for passage into an aperture in a rigid support, an attaching screw rigidly carried at the inner end of said body portion for securing the fastener element to the support, a laterally outwardly extending flange located at the outer end of said body portion, a front plate secured to said flange by a number of pedal-like portions bent inwardly from the outer edge of said front plate over the flange and positively interlocked therewith to prevent rotation of the front plate relative to said body portion and tool-receiving means provided by said front plate to permit turning said-fastener element :tor rota-ton of the attaching screw.

In testimony whereof, I have signed my name to this specification.

GUSTAV JOHNSON.
