Abstract

897,325. Sliding clasp fasteners. CRYSTAL, P. E. April 16, 1959 [June 6, 1958; July 30, 1958], No. 13027/59. Class 44. A sliding clasp fastener comprises a pair of tapes 12, 14 the innermost edges of said tapes being welted for the entire length of the tapes, mating fastener elements 16 secured to said welts on each of said tapes, a slider 28, bridging means 24 securely joining said tapes together at the lowermost portion of said tapes and an element free gap 26 between said bridging means and the lowermost elements carried by said tapes and said gap having a length appreciably greater than the length of the slider with said slider being movable along the welts in the said gap and along said fastener elements. As shown the bridging means is a bar tack but a clasp can be used if desired. Each of the tapes has a top stop 22 consisting of a plurality of non-mating nesting elements. The fastener is mounted on adjacent flaps 32, 42 of a cloth article by firstly applying a line of stitching 30 to join the tape 12 to the flap 32 with the slider in the gap adjacent the bar tack or clip; secondly by joining the tape 14 to the flap 42 by a second line of stitching 52. The lines of stitching are placed as closely as possible to the elements 16 by tilting the elements through an angle of 90 degrees before stitching so that when the elements are tilted into their original position they cover the lines of stitching. After the stitching has been finished the slider is moved on to the elements 16 and the bottommost portion of the tapes are cut along a line extending through the gap 28 a sufficient distance below the bottommost elements to allow room for a bottom stop. The seams 48 and 50 which join the flaps 32 and 42 together above and below the fastener are then extended to the top stop and bottommost elements so that the fastener presents the appearance of a seam which is continuous with and collinear to the seams 48 and 50 and a bottom stop is then applied to the welts of the tapes 12 and 14 adjacent the bottommost elements 16a.
