Abstract

112,645. Thompson, W. P., (Union Special Machine Co.). Dec. 18. 1916. Sewing-machines: cords. braids, and the like. attaching; folding-devices.-A sewing-machine is provided with means for inserting a tape or strip into a pocket formed by the folded parts of a fabric so that parts of the tape are in tension and other parts are untensiosed during sewing and is described in connexion with the insertion of an elastic strip in the waist-band of a skirt or like garment. The strip T, Fig. 3, is led to the needles 4, 5 along a guide 30 which is inclined to the line of stitching and is of channel shape, and under a block 35 carried by a spring-steel arm 38 which presses down on the strip with adjustable pressure and is pushed upwards by a rod 48 under control of the operator. The guide 80 is carried on a folder 21 for folding the edges of a waist-band B, and a folder is provided for folding the edge of the main fabric F. In this arrangement, two needles 4, 5, are used, making rows of stitches s, s<1>. When sewing those parts of the band that are intended to be flat, such as at the front of a skirt, the strip is fed along with the band and main fabric without tersion so that one edge is caught by the stitching s, and in sewing those parts of the band which are drawn or fulled, the block 35 is allowed to press on the strip thus causing it to stretch and become narrower in width and also to change slightly its direction of feed owing to the inclination of the guide, and so miss the stitching s. The machine may also be used for securing the strip in the 'pocket formed by folding over the edge of the main fabric F, as shown in Fig. 12, where 'one needle only may be used to stitch the turned edge f<3>. In further modifications, the guides and folders are arranged parallel to the line of stitching and the needle avoiding movements of the tape caused by narrowing it by tension, or they may be arranged to produce the article shown in Figs. 18 and 19 in which the elastic strip is enclosed in the band B and both are stitched to the folded edge of the fabric F. In this construction, the needles at all times penetrate the elastic strip which is fed with. out tension over the part from b to b' and with tension at the puckered parts. Reference has been directed by the Comptroller to Specification 112,638.
