ABSTRACT:
This disclosure relates to a four motion feed mechanism for sewing machines that is adapted to advance a workpiece past the stitch forming point of the machine. Orbital movement is imparted to the feed dog by a drive mechanism including first and second linkage assemblies driven off a common eccentric arranged on the sewing machine bed shaft. A feed regulating assembly including a single feed regulator control knob is operatively associated with one of the linkage assemblies to selectively pre-set the stitch length of the machine.
