SEPARABLE FASTENER,

Application filed December 2, 1921. Serial No. 519,381.

To aZZ whom it may concern:

Be it known that I, FRED S. CARR, a citizen of the United States, and a resident of Newton, in the county of Middlesex and State of Massachusetts, have invented an Improvement in separable Fasteners, of

hich the fol-lowing description, in connection with the accompanying drawings, is a specification, like characters on the drawings representinglike parts. 7

This invention pertains to improvements inseparable fasteners. It is among the objects of the invention to provide a separable fastener in which the stud and soc ket are positively locked against separation except pursuant to a desired manipulation, and in which a very short stud may be used.

In the drawings, which show a preferred form of one embodiment of my invention Figure 1 is a" vertical central section through a preferred form of fastener, being partlyin elevation;

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

Fig. 3 is a section on the line 22 of. Fig. 1, showing the position ofthe parts pursuant to that manipulation which permits separation of stud and' socket; and

Figs. 4 and? 5 are end and side elevations respectively of a part of the fastener illustrated'in Fig. "-1, and are more fully described hereinafter.

Referring to the drawings and to the preferred form of my invention selected "for illustrative purposes, I'have shown a stud includin ahead ,5, a, neck 6, and a shank portion "*secured'to a stud-carrying part 8,

which may be a portion of the body of a motor car or the like. Between the head 5 and neck 6 of the stud is preferably provided, as illustrated, a relatively abrupt shoulder 9. The preferred form of socket illustrated is secured to socket-carrying fabric 10, which may be a motor car curtain, and includes a casing 11 containing a sprin 12 having jaw portions 13 and let adapte resiliently to underlie the head 5 of the stud by entering the neck 6 behind the shoulder 9 of the stud. In the preferred form of spring illustrated, resiliency is provided to the

jaws

13 and 14 by forming the spring 12 of spring sheet metal and cutting away an almost complete annular portion 15 and b slotting the spring at 16 from the stu receiving aperture therein to connect with this annular cut-away portion 15 -Ojpp'osite 7 the slot '16, the spring is slotted at 1 ing l';l by which providesspring locating

In the ,form'o-f. my inyention illustrated, the spring .121 is held in the cas co, the, closure plate 118 (Fig. 1):,

While providing for manipulation ofthjegj aw means from apart projecting thrqugh the curtain and located on the outside Qt-et curtain on the side thereof oppositethe stud. When. the manipulatory part. '24; is turned" t Y fiQ'th v will press againstthe' adjacent faces 0f the spring in opposite directions and will spread the

jaws

13, 14 so that they will no longer underlie the head 5 of the stud. In the preferred form of my invention illustrated, it is not necessary to exert an outward pull on the socket to effect separation of stud and socket pursuant to this manipulatory movement because I have provided kick-off means typified by the kick-oil spring 28 located within the manipulatory part 24L and pressing a sliding disc 29 against the outer end of the head of the stud 5 so that as soon as the jaws release the head of the stud, the socket casing, including the spring, will be moved outwardly away from the stud so that, if the manipulatory part is again released, the jaws 13, 14: will not again enter the neck of the stud behind the head thereof. The sliding disc 29 is held in relation to the manipulatory part 24 by the projections 27.

The operation of the fastener herein de-- scribed is very similar to that illustrated in United States Letters Patent to Bourque No. 1,367,350, issued February 1, 1921. The construction of the fastener has, however, been improved from a manufacturing stand point and particularly in thatits parts have been so reorganized as to admit of the location of the jaw-containing portion of the socket on that side of the socket-carrying fabric from which the stud enters, so that a very short stud may be used. The use of a very short stud is desirable in many places,

particularly in connection with the fastenings of curtains on automobiles because of the improved appearance and because clothing, etc., is not likely to be caught and torn on a short stud. For many purposes fasteners difi'ering considerably in construction and operation from the one illustrated may be used to advantage while retaining the before-described principal advantages of my 2D invention.

l/Vhile I have shown and described a pre ferred 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.

1. A fastener comprising, in combination, a stud having a head and a neck, a casing containing jaw means for engagement in said neck of said stud behind said head, said casing and jaw means securedto a carrying fabric and located on that side of said fabric from which said stud enters, and manipulatory means on the opposite side of said fabric for disengaging said jaw means from said neck of said stud.

2. A fastener comprising, in combination, a stud having a head and a neck, a casing containing jaw means for engagement in said neck of said stud behind said head,

gage said jaws from. said neck of said stud. I

3. A separable fastener comprising, in combmation, a stud having a head and .a

neck, and a socket comprising a casing secured to a carrying fabric on that side thereof from which the stud enters, jaw,

means in said casing, a closure plate for said casing between said casing and said, fabric and clenched within a casing-securmg part on the opposite side of said fabric from said casing, and manipulatory means projecting through said casing-securing part and permitting stud-releasing movement of said jaw means.

4. A separable fastener comprising, in combination, a stud having a head and a neck, and a socket comprising a casing secured to a carrying fabric on that side.

thereof from which the stud enters, jaw

means in said casing, a closure plate for said casing between said casing and said fabric and clenched within a casing-securmg part on the opposite side of said fabric from, said casing, manipulatory means pro- 7 jecting through said casing-securing part and permitting stud-releasing movement :of

said jaw means, and resilient means associated wlth said mampulatory means for urging said jaw means toward said head of said stud pursuant to disengagement of said jaw means from behind said head of said stud.

In testimony whereof, I have signed my.

name to this specification. I
