Abstract

478,418. Sewing - machines. UNION SPECIAL MASCHINENFABRIK GES. July 27, 1937, No. 20682. Convention date, March 2. [Class 112] The machine has feed cups 1 which produce a multi - thread . overedge seam, a horizontal needle, and a main looper 5 which carries out the usual three-fold motion. An auxiliary looper 7 co-operates in the production of a two-thread or treble - thread overedge seam. In the case of a two - thread seam the device 7 acts as a loop spreader with a fish tail, and does not carry a thread. The driving rock-shaft 12 for the looper 7 is mounted above the needle bar 4 and guide rod 6 of the main looper. Links 13, 14, 15 transmit the rocking motion from the shaft 12 to a carrier 16. The thread-carrying looper 7 may be exchanged for a non-thread-carrying spreader. A thread-guiding eye may be arranged above the needle and loopers. A position of rest is imparted to the auxiliary looper in its upper position.
