Abstract

197,622. Thompson, W. P., (Union Special Machine Co.). Dec. 6, 1922. Sewing-machines; feed by dogs; presser-feet.-In a multiple-needle machine sewing a seam such as that shown in Fig. 7, the presser-foot 2, Fig. 4, is recessed as at 10 from the stitching point, to accommodate the overlapped portions of fabric and, in addition to the main portions 13, 14 of the feed-dog which engage the work on either side of the seam, a spring- pressed portion 19 is mounted in the forward end of the feed-dog to project above the surface of the main feed-dog and engage the overlapped portions after they pass from the stitching point. The portion 19 is pressed upwards by a spring 20 and is guided and limited in its movement by two bolts 16. A differential feed-dog may also be provided.
