Abstract

526,962. Sewing-machines; seams. UNION SPECIAL-MASCHINENFABRIK GES. March 27, 1939, No. 9458. Convention date, Oct. 26, 1938. [Class 112] Fringing-machines; intermittent feed; worksupports.-An ornamental edge seam or fringe as shown in Fig. 6 is produced on a zig-zag chainstitch sewing-machine by interrupting the feed and concatenating the thread loops with fingers 20, Fig. 5, in the needle aperture of the throat plate. The fingers 20 are shaped as shown to retain all the stitch chains until the work is fed forward while then allowing the chains to slip off easily. The lifting movement of the fourmotion feed-dog is produced by a worm-driven cam, on a vertical axis, with a peripheral groove engaged by the end of a lever on the feed-lift rock-shaft; the cam groove is straight except for notches at the points where feed is required. The cam may be made in two halves, so as to be easily interchangeable, the division between the two parts preferably being at an angle to the radius on each side or the hub for smooth working.
