Abstract
206,727. Thompson, W. P., (Union Special Machine Co.). Dec. 8, 1922. Sewing-machines; surface threads, attaching. - In a multiple-needle sewing-machine for producing an over-edge seam, suitable for uniting fabric sections to form a pocket &c. and having fabric-trimming means, one member of the loop of a cross-thread, concatenated with the needlethreads by a reciprocating hook, is positioned to pass between the needles by a finger 17. The cross-thread c, Fig. 2, passes to the work through a guide-edge and over a cam-faced arm 16 and lies in the path of a hook 14 pivoted centrally on the presser-bar 10. The finger 17 adjustably mounted at 18 on the presser-bar engages the limb c<1> of the loop formed by the hook and deflects it so that it passes between the needles 6, 7. A second finger 160 is provided to ensure the correct position of the cross-thread for engagement by the hook 14 whatever the variation of the feed. This finger is adjustably mounted on the presser foot behind the needle 7, and is formed with a blade 163 in a vertical plane having a downward projection 164 and a backwardly curved part 165. Trimming or cutting.-A trimming device 20 is arranged in front of the needles and the hook 14, the strip cut off being defected by a deflector 21. Multiple needle machines; seams. - A third needle 8 is mounted to one side of an behind the needles 6, 7 and a separate threaded looper 22 cooperating therewith is mounted on the same rocker as the looper 11 of the needles 6, 7 so that a single line d of double-loop stitches is produced alongside the stitches formed by the needle and. cross-threads a, &c.
