Abstract
868,964. Sliding-clasp fasteners. NEW ZIPPER CO. Ltd., and DOELTER, G. Sept. 27, 1957 [June 29, 1956], No. 20258/56. Class 44. In a sliding-clasp fastener of the kind in which each stringer 20 has a series of elements 22 which are held within a fold in a sheet or strip of flexible material and are arranged to interlock with elements of the other stringer 20, the clasp is provided with a plough 27 to separate the stringers when the fastener is being opened and, when the clasp is at the closing end of the fastener, the plough is withdrawn from between the stringers by a cani action between itself and an end stop 50. The stringers 20, Figs. 1 and 3, are constructed as described in Specification 723,998, although the tips of the inner elements 22 may have to be flattened to facilitate movement of the plough, and the heads of these elements are removed over a short length of the fastener at the closed end thereof to allow the plough to be withdrawn from and reenter between the stringers. The clasp, Fig. 2, comprises three major-parts viz. a body 25, an outer shell 26 and the plough 27, which latter is urged between the stringers 20 by a spring 40 and is provided with bosses 38 for pivoting in notches 39 on the body 25, and between the body 25 and the outer shell 26 are provided spaces for receiving two side arms 54, 55 of the end stop 50 when the fastener is closed. Secured to the arm 54 is a spring catch 61 for locking the clasp in the closed position, the free end 63 of the spring catch engaging an abutment on the inside of the shell 26, Fig. 9, and provided on the shell 26 is a slide 68 having a finger grip 69 for moving the slide against the action of a spring 76 to disengage the spring catch 61. Alternatively, a spring catch may be mounted within a recess in the top of the shell 26 to engage notches in the arms 54, 55 of the end stop 50, a member being provided for disengaging the catch. To avoid the plough rubbing through the flexible material when it engages with the end stop it may be provided with pins which ride on cam faces on the inside of the side arms 54, 55 of the end stop 50 or in cam slots therein, in which latter case the plough will be forced between the stringers when the clasp is moved to open the fastener. Specifications 769,535, 769,536, and 769,537 also are referred to.
