Abstract

The machine of the Parent Specification, in which the needle thread is tensioned only at the time of stitch forming, is modified by providing the feed dog 7 with a needle aperture 14 and a recess 7A immediately downstream of aperture 14. A projection (9) extends 'laterally from the needle plate (8) into recess 7A and supports the work while a stitch is being set, when dog 7 has descended out of contact with the work. The needle 6 is carried by an arm 15B connected by a link 15A to a disc 15 on a rotary shaft 26, and also connected to a lever 16A with a forked end embracing a cam 16 on shaft 26. Feed lift movement is imparted to dog 7 by a linkage 18, 19 actuated by a cam 17 on shaft 26. Feed advance movement is imparted by a two-part lever 21, 22 with a fork end embracing a cam 20 on shaft 26 and connected to dog 7 by a link 23. The latter engages an abutment 24 to limit the feed stroke, a lost-motion connection comprising a spring being provided at the junction of the parts of lever 21, 22.
