Abstract
A stitch length and reversing control for a sewing machine is uniquely arranged to facilitate the selection by a machine operator of the length of stitches to be formed in a work piece, to enable the operator at a convenient location on the machine to quickly reverse the direction in which work is fed from a forward feeding direction to a reverse feeding direction, and to enable the operator to sustain the operation of the machine in a reverse feed mode with hands off the control.
