socket by relativetippingaction after the parts have assumed the. position in F ig. 3 Fig. 'is a front elevation of the stud; Fig. 6 is a rearelevation. of the stud; .Fig. 7 is av section on the line 77 of Fig. 1, showing the means of attaching the'stud to a curtain; Fig.8 is a front elevation of the socket Fig. 9is a side elevation of the socket and Fig. 10 is. a section of a portion of a socket showing aataper'ed locking member. Referrin, to' the drawings and to the preferred formofmy in'ventioml have shown a socket including a casing 1 presenting a stud-receiving aperture, a screw 2 for' attaching the'casing to thebody 3 ofan automobile or the like, anda spring-.pressed'lockin g member; 4 normally surrounded .by' the stud-receiving. aperture. v v

The socket, as illustrated, except for the locking member, is substantially like the one illustrated and described in the co-pending "application of Andrew G. Anderson, Serial No. 708,724, filed April24th,z192 l. The preferred form of stud illustrated'is of very simple and inexpensive construction and'comprises a socket-engaging contractible and expansible head struck up from a single sheet of metal and having a substan- =15 tially long neck 5 for engagement with the stud-receiving aperture. The 'base 6 ofthe stud presents a plurality of prongs 6(Figs. 6 and 7), which are adapted to pierce the stud-carrying fabric such' as the curtain 7 of'an automobile, thereby to engage and be clenched outwardly and downwardly by a one-piece clench plate. 8 located upon the frontside of, the curtain.

A latch 9 is pivoted upon the stud nie'm- I 1924; 1 semi 1%.- 719,924.

and.operates ina slot therein, to displace .the locking member as more fully hereinafter describedyThe .latch'is held in posiprovides a-smooth guidingsurface for. the latch, as best illustrated-in Figs-.,2, 3,'4eand 6. .This ear 10 extends inwardly from the edge of thebaseG? (Figs. 2and 6 and is by the front plate when the stud is attached to the; curtain. g r. fiThe fcle'nch plate presents a false;pressbutton, 1-1 integral; therewith to designate the amma, assaentsms assmma To CARR rA'sTnNER COMPANIV' tion. an inwardly bent ear,10, which also .maderelatively wideso as to be supported point at which thefastener may be pressed to engagefthe studwith the'socket. ,Pressure upon thispress-button?" causes the head of thestud to enter thestuchre'ceiving aperture ,nr the socket and contractflsli'ghtly before coming into contact with the lockingfmember l, Thus thelockmg member is excluded 1 from thestu'd and is -urge jd inwardly until the head'of the stud passes through theaperture whereby it again expands and the lockvmg member urged intothe head of the stud, thus locking. the stud and socket together and preventing separation thereof by a strain exerted at-any side of the fastener,

WVhen the stud and socket are locked together, as illustrated in Fig.2, the inner end .12'of'the latch is engagedby the.'locking member and swung about its pivot until the outer end 13 of the latch is seated against the front face of the socket. As illustrated, the spring-pressedsealing disc 14; urges the stud outwardly from thesocket until that portion of the head of the stud, beyond the neck, is seated against the peripheral .wall

surrounding the stud-receiving aperture.

Separation ofthe stud from the socket maybe effectedby exerting pressure upon the false press-button, thereby urging the stud bodilytoward the socket, which movement is permitted by the relatively long neck .which may slide relative to the wall surrounding the stud-receivingaperture. This relative axial movement between the stud and the socket exerts pressure upon the outer end 13 of the latch, thereby tipping it about its pivot whereby theinnerend' 12 of the latch moves the locking member out, of engagement with the contractible and expansibleihead, asbest illustrated in Fig. '3. The

stud may now be separated from "the socket by grasping the lower edge of the'curtain and exerting a slight pull thereon, as illustrated in Fig. 4. y p p By providing the. socket with a tapered locking member, as illustrated in Fig. 10,

the stud may be separated from thesocket, by an outward pull at the bottom; of the curtain, without the initial inward pressure on the stud, the lever 9 being rocked by the resolution of forces, sufficiently to start the locking member a out-of locking position and the taper thereof progressively increasing the clearance as'the stud is tipped out of'the socket. upward pull on the curtain would by reso- In such case, however, an

lution of forces produce a similar tipping movement, making the fastener less secure 'a-nd'dependable for uses where the stud-car- 'rymg medium may exert an upward pull on thesocket. To prevent this resolution of forces arising from an upward pull, I have provided on the socket an abutment,herein shown as the inner face of the ringlike peripheral bead 15 provided on the front face of the socket.- The upper edge of the adjacent end 13. of the lever 9 abutting against the inner faceof the bead 15, rocks the lever "9 ,inthe opposite directionfrom that which --moves the locking member 4 out of locking position. This abutment is provided whether the locking member has straight or tapered sides so as to insure against separation of the stud and socket by an upward strainon the curtain. v v While I have shown and described a preferred form of oneembodiment of my invention, it will be understood that changes in volving omission, alteration, substitution and reversal of parts, and even changes in the mode of operation, may be made'without depar'tingfrom the scope 'of my invention, which is best defined in the'following claims.

I claim- I 1. A separable fastener comprising, in

combination, a flush type socket having a front face, a stud for application to a flexible carrying medium, said stud having a head for engagement with said socket, looking means carried by said socket for locking said stud and socket together and unlocking means carried by'said stud, said unlocking means having a portion for engagement with the front face of the socket and another portion for engagement with the locking member whereby movement of the stud toward the socket operates said unlocking means to shift said locking means and permit separation of said stud and socket.

2. A separable fastener comprising, in combinatioma stud element and asocket element, said socket element having a front face, locking means carried by one of said elements for locking them together and unlocking means carried by the other of said elements, said unlocking means having 3.
