'rns'rnnnn Specification of Letters Patent.

Patented Apr. as, 1919.

Application filed August as, 1917. Serial No. 187,804..

To all wltom it may concern Be it known that I, Mosns, F. CARR, a

citizen of the United States, and a resident vented an Improvement in Fasteners, of'.

which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention pertains to improvements in fasteners, and more particularly, though not exclusively, to snap fasteners primarily intended to hold on securely the flaps of pockets containing clips of cartridges, readily permitting separation of the two parts of the fastener so that the flap can be raised and the clip of cartridges removed from the pocket, while reducingto a minimum the chances of accidental separation of the fastener and resultant loss of ammunition.

In snap fasteners as ordinarily constructed, if the flap of the pocket were raised accidentally in climbing out of a trench or by catching on the bough of a tree or the like, the socket portion of the fastener would be separated from the stud portion thereof. The use of those types of separable fasteners requiring any considerable manipulation for separation of the parts is disadvantageous because valuable time may be lost on account of failure to immediately perform the correct manipulation. In the present invention the amount of manipulation necessary to open the devicje is reduced to a minimum.

In the drawings:

Figure 1 is an elevation of a" preferred form of one embodiment of my invention;

Fig. 2 is a section on the line 22 of Fig. 1;

Fig. 3 is a section on the line 33 of Fig. 2.

Referring to the drawings, 4 represents the side of a coat, 5 the outside of a pocket and 6 the flap of the pocket. The stud 7 is attached to the outside of the pocket 5 by any suitable means and provides a round head 8 and a neck portion 9 providing shoulders, preferably abrupt, between the neck 9 and the head, 8. The socket is attached to the flap 6 of the pocket and preferably comprisesa front plate 10, intermediate plate 11 and back plate 12. The front plate 10 is preferably flanged at the edges to provide a recess for a spring 13 which provides jaws I 14 and 15 extending transversely of the socket. The jaws 14: and 15 are preferably held apart by a projection 16 interposed between their ends. When the rounded head of the stud 8 is pressed between the jaws 14k and 15, the jaws are spread and engage the neck 9 of the stud. As before stated, the shoulders provided between the neck 9 and head 8 are preferably sufficiently abrupt to prevent separation of the stud and socket by rectilinear movement. Said shoulders are also preferably sufliciently abrupt to prevent separation of the jaws 14 and 15 by tipping movement of the socket relative to the stud in a direction transverse to the jaws. Relative tipping movement of the stud and socket in a directionlongitudinal of the jaws 14.- and 15 is preferably prevented by the intermediate plate 11 or the back plate 12 or both of said plates.

The aperture through the intermediate and back plates is preferably such as to permit tipping movement of the socket relative to the stud when the bottom'of the flap 6 is pulled outwardly. As before stated, however, this alone will not open the fastener because of the engagement between the abrupt shoulder of the stud and the jaw 15. When, however, the flap 6 is pulled down- 'wardly and outwardly in the direction shown by the arrow in Fig. 2, the jaw 14 is pressed upwardly by the stud 7 while the jaw 15 re mains abutted against the stop 16 of the socket casing. Therefore the jaws '14: and 15 are separated sufficiently to permit the head 8 of the stud 7 to slip between the jaws 14 and 15, thereby opening the fastener andpermitting removal of the contents of the pocket. In practice the stud and socket are so proportioned that a quick jerk in a downward and outward direction will effect this opening. It is obvious that movement in this direction can only be effected in oneway, v-iz.,' by graspin the bottom of the flap of the pocket in a su ciently firm manner so as to be able to exert tension thereon in the desired direction. 7

While I have shown and described one embodiment of my invention, it is obvious 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 comprising, in combination,

a stud, a socket, jaw means carried by said socket for engagement with said stud, and means cooperating with said jaw means providing for opening thereof on diagonal movement of said socket in a direction transverse to, away from, and in the direction of the longitudinal axis of said stud.

2. A separable fastener comprising, in combination, a stud, a socket, a plurality of resilient jaws carried by said socket, stop tively interposed between the ends of said jaws; said socket permitting bodily transverse movement of said socket relative to said stud to a position where one of said jaws is disengaged from the abrupt portion of said shoulder.

4. A stud and socket fastener comprising, in combination, a stud having a head and a neck with an abrupt shoulder interposed therebetween, a socket providing two sub-- stantially parallel jaws for engagement with opposite sides of said neck and means permitting disengagement of one of said jaws from the abrupt portion of said shoulder, thereby to permit separation, of said socket from said stud on continued tipping movement of said socket relative to said stud in a direction transverse to said jaws.

-, 5. A stud and socket fastener comprising,

in combination, a stud having a head and a neck, an abrupt shoulder interposed between said head andneck, a socket having a casing, a resilient spring inclosed in said casing and providing two resilient jaws, a stop interposed between the ends of-said'jaws and means permitting limitedtippin movement of said socket relative to said stud in a direction transverse to said jaws, thereby to permit separation of said stud from said socket.

6. A stud and socket astener comprising, in combination, a stu 7 having a head 8 and a neck 9, an. abrupt shoulder interposed between said head and said neck, a socket comprising a casing 10 having a spring 13 therein providing. resilient aws 14 and 15, and a stop 16 interposed between the ends of said jaws. j

7 A stud and socket fastener comprising, in combination, a stud havin a head and a neck; a socket therefor having jaw means and means opposing separation of said socket from said stud by rectilinear movement ofsaid socket relative to said stud or by tipping movement alone, while permitting separation of said socket from said stud by combined transverse and outward .movement of one side of said socket relative to said stud.

8. A fastener for the flaps of cartridge pockets providin a stud 7 attached to the outer portion 0 the pocket, a socket attached to the flap 6 of the pocket, jaw means carried b said socket for enga ement with a reduce portion-of said stud g and means opposing separation of said stud from said socket by rectilinear movement of said socket relative to said stud or by relative tipping movement alone, while permitting separation of said socket from said stud by a combined downward and outward pull on the bottom of said flap.

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

MOSES F. CARR.
