FASTENER.

Application led June 14,

This invention aims to provide an i1nproved separable fastener.

In the drawings, which illustrate a preferred embodiment of my invention Figure 1 is a front elevation or' the preferred form of fastener;

Fi 2 is a section on the line 2-2 oi' Fig. 1, being partly in elevation;

Fig.`3 is a se tion similar to Fig. 2, showing the relation of the parts of the stud when being unlocked from the socket;

Fig. `4 is a section similar to Fig. 2, showing the relation of the parts of the stud when the head is being entered into the studreceiving aperture;

Fig. 5 is a section on 2.

,Fig 6 is a section on the line 6-6 of Fig. 2; and

Fig. 2.

Referring to the drawings and to the preferred form of my invention, as illustrated, 1 have shown a socket 1 including a studreceiving aperture, sealing means, and an attaching screw 2 for attachingy the socket to the body 3 of an automobile, substantially as illustrated and described in the copending application of Andrew G. Anderson, Serial No. 708,724.

The stud may be secured to the curtain 4 of an automobile in any suitable manner, but I prefer to provide a back, plate 5, located upon that side of the curtain nearest the socket, presenting a plurality of attaching prongs 6 which pass through the curtain 4 and are clenched preferably outwardly and downwardly by a clench plate 7 located upon the opposite side of the cui tain. This clench plate also presents an elongated aperture 8, the purposes of which are more fully hereinafter described.

The preferred form of socket-engaging means includes a socket-engaging member presenting a head 9 having a neck 10 .for engagement with the socket and a locking member 11 slidably mounted within the head and presenting a fin-like part 12 through a longitudinal slot 13 located in the head diametrically opposite the neck 10. This locking memberv is normally `urged forward by a spring 14 interposed between one end of the line 5*-5 of Fig.

7 is a section on the line 7-7 of Fig.

. the locking member 11 and the inner face A of a cap 15, which fits over the end of the 1924. Serial N0. 719,934.

socket-engaging member, thereby holding the spring in place and presenting a finished appearance to the stud when assembled to the curtain, as illustrated. in Fig. 1.

To permit relative tipping movement between the clench plate 7, curtain 4 and back plate 5 as a unit or casing and the socketengaging means, I have provided a substantially deep recess 16 in the head 9 which is adapted to receive the pivot 17 located o u the back plate adjacent the top of the preferably rectangular aperture 18 in the back plate through which the head passes. This pivot is provided by a reversely bent portion which presents a smooth rounded surface for cooperation with the recess 1G. The wall at the bottom side of the aperture presents a reversely bent edge for normal engagement` d with the in-like part 12 of the locking member and, also for engagement with the depending finger 19, when the back plate is pivoted relative to the socket-enga means, as more fully hereinafter described.

Assembly `of the parts of the stud is as follows. The socket-engaging head 9 is first entered through the aperture 18 in the back plate 5 until the recess 16 is opposite the pivot 17 and the locking member 11 is then placed in the head 9 with the nlike part 12 projecting through the slot 13. Vhen pushed forward, the fin-like part engages the periphery of the rectangular aperture 18 diametrically opposite the pivot 17 and urges the pivot into the recess 1G, thus hold-l ing the back plate and head together as illustrated in Figs. 2, 3 and 4@ Next the spring 14 is placed in the socket-engaging member and the cap is driven over the outside of the socket-engaging member, thereby holding all of the above-mentioned parts in place prior to assembly thereof to a curtain.

The stud may be vsecured to the socket by pressure upon the cap, which projects through the elongated aperture in the clench plate, thus urging the head 9 of the stud into the stud-receiving aperture, and, as best illustrated in Fig. 4, the eam-shaped end 2() of the locking member contacts with the edge of the socket adjacent the periphery of the stud-r`eceiving aperture, thus holding the locking member out of the aperture until the head 9 has passed therethrough and the neck has been engaged therewith. The

ning

spring 14 then urges the locking member forward and the socket-engaging member shifts relative to the stud-receiving aperture to engage the neck thereof with the periphery of the stud-receiving aperture, thereby to permit engagement ofthe fin-like part` 12 of thelo`eking` member with the` stud-receiving" aperture,' as "best illustrated Then in the position illustrated'. in this figure, the stud is looked with the in Fig. 2.

thereon, which causes theback plate and 17 relative to the socket-engaging member. Thus the `reversely bent ortion Aof 'the back plate adjacent the tin-li e part 12'engages the depending linger 19 and' .moves 4the lockingmember relative to thesooket-engaging member untilythe cam-shaped portiony 2O is adjacent the periphery of the stud-re ceivilngy aperture, `as best .illustrated in Fig. 3. I i

Then asa further pull is exerted upon the curtainthe socketenga ing means may tip relative to the socket and become disengaged therefrom. g This relative tipping movement between the clench plateyand the outer end of the socket-engaging member is ermitted b the elongated,slotfprovidedin t e face of tliye, cleneh plate.I Thus the rst part of the tipping action releases the locking member softhat Athe last 4part, of the tipping action :tips the socket-engagingnhead out oflengagement'withthe socket. i While I yhave shown and described .a preferred `form of one embodimentoi my inclench plate or casing to tip about the pivot vention, it .will Abe understood that changes involving omission, alteration, substitution and reversal of parts, and even changesl'n the mode of operation, may be made Without departing from the seopeof my invention which is best defined in the followingelaims.
