Title: A two thread chainstitch sewing machine
IPC: D05B1/10
Filed: 1962-10-29
Abstract: 948,866. Sewing machines. MAN-SEW CORPORATION. Oct. 29,1962 [Nov. 13,1961], No. 40779/62. Heading D1G. A two-thread chain stitch sewing machine comprises a threaded needle, a threaded looper, a spreader adapted to engage the looper thread to form a thread triangle for entry by the needle, and a thread interceptor adapted to engage the looper thread extending between the spreader and the previous stitch and to move from one side of the needle path to the other side thereof, whereby said triangle is formed regardless of the direction of work feed. The looper 89 is carried on an arm 88 oscillated transversely of the line of feed by a connecting rod 81. The spreader 36, which is oscillated in the line of feed and has two arms between which the needle reciprocates, is carried by an arm 30 pivoted on a shaft 31. A pitman 32 connects arm 30 to a crank pin 29 on an eccentric 101 rigid with a driving shaft 12. The thread interceptor 121, formed with a thread-engaging notch 123, is pivoted at 119 to the upper part of a frame 108 having spaced arms 109, 110 which are pivoted on shaft 31. A pitman 103 connects frame 108 to eccentric 101. The thread interceptor is also formed with a cam slot 124 engaging a fixed pin 125. The arrangement is such that the spreader and thread interceptor oscillate in the line of feed in opposite directions, the notched end of the interceptor initially travelling along the outside of the right hand arm of the spreader and then moving across the line of feed to a position above the left hand arm of the spreader. During forward feed, the interceptor when engaging the looper thread extending from the right hand arm of the spreader to the work, serves merely to enlarge the thread triangle through which the needle passes. During reverse feed, as shown in Fig. 3,the interceptor is moving opposite to the direction of feed engages the looper thread to produce a thread triangle which would otherwise not be formed, owing to the last stitch in the work being situated in front of the looper. It is stated that the feed may be immobilized and the work moved manually in any direction without causing skipped stitches. In a modification, Fig. 7, the spreader and interceptor are driven from separate sources. The interceptor 143 is carried by a member 138 which is pivoted about a vertical pin 140 carried by a member 141 fixed to a shaft 31, member 138 being oscillated by a converting rod 136 from the shaft that drives the looper.
