450,823. Sliding clasp fastenings. UNITED-CARR FASTENER CORPORATION, 31, Ames Street, Cambridge, Massachusetts, U.S.A.-(Assignees of Murphy, H. J. ; 9, Bowdlear Road, Greenwood, Massachusetts, U.S.A.) Feb. 11, 1936, No. 4130. Convention date, Feb. 27, 1935. [Class 44] A completely separable sliding-clasp fastener has a top stop formed by laterally projecting ears 24 on a plate 21 bent over the beaded edge of one stringer 2 and the beaded portion 23 of such plate is abutted by the ends of the topmost fastener elements of the other stringer 5. If the fastener elements accidentally become separated below the slider the stringers can be disengaged by hand up to the slider and the said other stringer 5 can then be pulled through the slider. The stringers can later be re-engaged in the ordinary way starting from the separable bottom stops 14. An abutment plate 26 on the said other stringer 5 serves to prevent displacement of the said topmost fastener elements. The bottom stops comprise a member 1 with a base loop 10 into which is inserted the thin end 13 of the pin member 4 after the latter has been threaded through the slider. The bottom stop member 1 also comprises fingers 12 engaging the lowermost elements of the opposite stringer. The bottom ends 3, 6 of the stringers are beaded by slitting the tapes, twisting the beaded edges 90‹ and then sticking down the flaps 14, 15.
