UNITED STATES PATENT OFFlCE.
FRED S. CARR, OF NEWTON, MASSACHUSETTS, ASSIGNOR TO CARR FASTENER COM- PANY, OF CAMBRDGE, FAESSACHUSETTS, A CORPORATION OF MAINE.
FASTENER.
This invention aims to provide an improved separable fastener.
In the drawings, which show an illustrative embodiment of my invention Figure 1 is a front elevation of a preferred form of fastener;
Fig. 2 is a rear elevation of the socket as attached to a curtain;
Fig. 3 is a section on the line 3-3 of Fig. 1, being partly in elevation;
Fig. 4 is a section on the same line as Fig. 3, showing the operation of the fastenerI when the socket is being` engaged with the stud;
Fig. 5 is a front elevation of the stud; and
Fig. 6 is a section onthe line G-G of Fig. 4.
Referring to the drawings and to the embodiment of my invention selected for illustrative purposes, I have shown a stud secured to the body 1 of an automobile or the like by a screw 2 held by the casing '3 of the stud.
The front plate 4 provides a contractibe and eXpansible head 5, which is entirely Within the body 3 of the stud and is adapted to receive the stud-engaging part of the socket. The stud illustrated is substantially like that shown and described in my copending application Serial No. 719,928, filed herewith, except as hereinafter described.
The preferred form of socket is secured to the curtain 8 by the use of a back plate 9 presenting a plurality of attaching prongs 10 which pierce the curtain and are secured to the socket in substantially the same manner as illustrated and described in the above` mentioned application. The socket includes a tubular stud-engaging ortion 6, anvil parl: 1l, clench flange 12 and front plate 13, all of which are substantially like those parts il lustrated and described in the above-mentioned application. The socket also includes a locking means comprising a locking part T normally projecting beyond the stud-engaging part, a press-button part 14 presented through an aperture in the front plate and an enlarged shoulder 19, which provides seat for one end of a spring 18 also seated aga-inst the front plate to urge the locking means into its normal position. The locking means is limited in its forward movement by the reduced end portion of the studengaging part 6, against which the shoulderv Application filed June 14, 1924. Serial No. 719,929.
19 is seated when the locking means is in its normal position.
Engagement of the socket with the stud is effected by pressing upon the press-button and urging the socket toward the stud. The locking part rst passes through the opening in the head of the stud and engages a hatshaped disc 16 normally urged toward the base of the stud by a spring 17. The disc 16 is moved inwardly against the pressure of the spring and the reduced end of the studengaging part is forced over the head of the stud, which is permitted to contract because the locking part is, at this point (Fig. 4), beyond the reversely bent portions 2O located upon the head of the stud. When the reduced portion of the socket-engaging part (5 is engaged back of the head of the stud, thc head expands and the locking part is forced by the substantially strong spring 17 acting against the pressure of the relatively weaker spring 18, into engagement with the reversely bent portions 20, thereby preventing contraction of the head and withdrawal thereof from the socket, as best illustrated in Fig. 3.
Separation of the fastener is effected by grasping the lower edge of the curtain 8 and exerting a. slight pull thereon, at the same time pressing the press-button 14 to displace the locking part from the reversely bent portions 20 to permit contraction of the head of the stud and Withdrawal therefrom of the stud-engaging part 6 of the socket.
lVhile I have shown and described a preferred form of one embodiment of my invention... it will be understood that changes involving omission, substitution, alteration 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:
l. A separable fastener comprising, in combination, a stud including a casing presenting a contractible and expansible head surrounded by said casing, a socket presenting a rigid stud-engaging part for engagement with said head, a locking member forming part of the socket assembly and adapted to pass through said head before engagement of said stud-engaging member therewith and resiliently pressed means located in the stud for movingsaid locking ,member into engagement with, said head,
thereby to prevent separation of said socket from said stud by a strain exerted at any side thereof.
2, A separable fastener comprising, in combination, a stud incliuling a casing presenting a contractible `and expansible head surrounded by said casing, a socket presenting a. rigid stud-engaging part for engagement with said head, a locking member forming part of the socket assembly and adapted to pass through said head before engagement of said stud-engaging member therewith, resiliently pressed means located in the stud for moving said locking member into engagement with said head thereby to prevent sepa-ration of said socket from said stud by a strain exerted at any side thereof, and a manually operable press-button also forming p-art of the socket assembly for moving said locking member out of engagement with said head against the pressure of said resiliently pressed mea-ns thereby to permit separation of said socket from said stud.
3.

A separable fastener comprising, in combination, a stud including a casing presenting a contract-ible and expansible head surrounded by said casing, a socket presenting a tubular stud-engaging part, springpressed locking means axially located in said stud-engaging part, said locking means presenting a locking part normally extending beyond the free end of said stud-engaging part to pass through the head of said stud before engagement of said stud-engaging part with the head of said stud, thereby to permit contraction of said head and engagement of said stud-engaging part therewith, a spring-pressed disc in said stud for i thereto, a
moving said locking part into locking engagement With the head of said stud thereby to prevent contraction'thereof, and a manually operable press button presented by .said locking means for moving said locking part against the pressure of said spring-pressed disc out of engagement with said head thereby to permit separation of said socket from said stud.
A separable fastener comprising, in combination, a flush type stud secured to a rigid support, said stud including a casing and a contractible and eXpa-nsible head counter-sunk within said casing, a cooperating socket secured to a. flexible support, said socket presenting a tubular stud-engaging part for engagement with the head of the stud` locking means forming part of the socket assembly for locking said stud and socket together, and a spring-pressed manually operable push-'button also forming part of the socket assembly, said push-button adapted when pressed to move said locking mean-i into unlocked position by movement thereof toward said stud when the stud and socket are engaged.
t3. A stud for a 4separable fastener including a casing, an attaching member secured thereto, a socket-engaging head surrounded by said casing and a spring-pressed disc located between said head and said attaching member for moving a cooperating locking` member into engagement with said head.
7 A stud for a separable fastener including a casing, an attaching member 'secured contractible and expansible socket-engaging head surrounded by said casing and a spring-pressed disc operatively located between said head and said attaching member for automatically moving a cooperating locking member into engagement with said head.
8. A stud for a separablel fastener including a casing, a. socket-engaging stud member located in said casing and having its head, neck and base located adjacent to the outer end thereof in fixed relation thereto, a reciprocable element in said casing behind said socket-engaging member and means secured to and eritenvding axially from said casing adjacent to the inner end thereof for securing said casing to a support.
In testimony whereof, I have signed my name to this specification.
