' CURTAIN" FASTENER.

Application filed February 20, 19 24. SerialNo. 693,972. i Q

' My invention has particular reference to 'curtain-fastenersadapted for use on automobiles though as will appear from the drawing and specification it islikewise adaptable to other uses; It isthe object of the invention to provide a so-called snapfastener I which will not disfigure the frame of the automobile when the curtains are not in place, which is easy and certain of manipulation and which will Securely hold the curtains in place.

I "In the drawings accompanying and form- 'ing a part of this application, Fig. 1 1s a diametrical section through a curtainfas- 'tener embodying my invention, parts being shown in elevation; Fig.12a face vieW'of-the memberof the fastener attached to the curtain 'viewed from the outside; Fig; 3 a simi- 5 larview from theinside of the curtain and Fig. t an end-view of the socket orframe member of the fastener. I

The-socket or frame member of'the fastener comprises a barrel. 5 which maybe cylindrical inform and'which at 'itsinner end is reduced as at 6and given an angular form 8 of form corresponding to the reduced, porthe outer periphery of which is preferably in. place by peening or pinching'the barrel slightly over, the head of the vscrew as;at. 10. The upper or outer end of the barrel is formed withan outwardly extendingflat flange 11,

a hexagonal or octagonal and an annular catch member 13 is applied to saidfiange the edge of the catch member being bent under the flange at lJto secure the parts firmlytogether. The outer end of the barrel isthus provided with an angular head to whlch a wrench may be appliedfor the purpose of driving the screw 7 into the wood of the frame memberin whichthe socket is im bedded. The annulus 13 projectsinwardly and is given a slightly funnel-shape at 15 the inner edge terminating in a bead 16'.

Within the barrel 5-is a follower. 17I'which is. normally pressed outward against the :.-bead 16 on the catch memberby aspring 18 in the barrel. *TheYfollowerQl'? is formed with a cylindrical flange 19 toguide it in. the barrel and also witha central" boss 20" 1 ing in the ann'ular'cat ch which n-ormally projects through the-openfor a purpose which will appear.

' The curtain elementnof the fastenercomprises 'aiifle'xible cylindrical catch whichflis pressed into the annular catch: of thesocket,

contracting sufliciently to clear thesame and i then expanding to interlock therewith. The

spring catch 21 comprises a fiat annular base 1 Q2 and a generally cylindrical entering portion 23 which'terminates in an outwardly proectmg bead 26. The enteringflpo rtion is split long tudinally into a convenient number of sections, here "shownat 26, the slits 2T extending nearly to the base. -The bead 26 "I on the end of the entering member is of slightly larger external diameterthan theinter- .nal'diameter of the bead 16 of the annular catch of the socket. Hence when the split entering member is forced against the annular. catch of the socket the spring catch or entering member contracts to permit its bead 26 to pass the'bead 16and then expands 'to normal diameter so that the beads are in looking engagement. The-boss or projectionQQ on the follower of the socket member, here:

tofore mentioned is of a diameterto freely-- Y enter the spring entering member or catch when the latter is 1n normal expanded con dition butto prevent sufficient contraction of I v of to passthe bead 16 of the socket. Therefore when the entering member'of the curtain the entering member to permit the bead there-.

element. of the fasteneris pressedinto the socket the follower in the latter yields until the bead 'onthe entering'member passes the beadon the socket and then the follower is I returned by its spring into contactwith the" end of the entering member but with its boss 20 within: the end thereof. The parts of the.

fastenerare thus firmlylocked together and the entering' member cannot be withdrawn until the boss of the follower is forced out, of the end thereof so ber inay contract.-

member of the fastener, the inner end therethat the entering mem In order to expel the boss ofthe follower from the endof the entering meinber when: .the curtain is tobe unfastened a plunger or push button 30"is ;1nounted in the curtain rounds the plunger and bears at its inner end on a seat or shoulder 34 provided for this purpose byv reducing the diameter of themner portion of the split barrel. The other end of the spring bears against a collar35 formed on the push button or plunger.

The housing for the operating elements of the curtain member of the fastener comp-rises a back plate 86 against which the flange 22 of the locking member rests and a concavoconvex front plate 37 the outer edge of which is turned over or upset at 88 about the edge of the back plate 36 thus firmly locking the two plates together and fixing the locking member. The front plate is formed with an opening 39 through which the end of the push button extends and which is engaged by theflange on the push button or plunger to limit its outward movement; The back plate 36 is formed with a rearwardly extending sleeve H) which surrounds the entering member for a portion of its length. Awashwill receive the body of the socket but fit the same snu l and then b the use of a wrench r on the outer end of the socket driving the attaching screw thereof home, To secure the respective members of the fastener together they are broughtinto registry and a slight pressure is sufiicient to drive the entering member home when parts assume the position shownin Fig. 1; To separate the members of the fastener the push button is pressed in to drive back the follower of the socket after which the entering member may be readily withdrawn. In actual use the thumb is inserted under the edge of the curtain and a finger pressed on the push button so that by singleniovement of the hand the parts may be separated.
