ABSTRACT:
A work feeding mechanism for sewing machines including a feed dog with two pair of mutually orthogonal serrated teeth to drive a fabric past a stitch forming area in directions defined by mutually orthogonal axes. The feed dog is slidably mounted to a bracket which in turn is pivotally fastened to one extremity of a feed bar whose opposite extremity is suspended by gimbals carried in the bed. Means are disclosed to selectively impart oscillations of a varying amplitude and direction to the slidable feed dog in timed synchronization to the work feeding mechanism to drive the feed dog in lateral and longitudinal directions of fabric feeding motion which extend along the length of the sewing machine bed and normal to the length of the bed. Fabric feeding information for the work feeding mechanism may be stored in an electronic memory to permit the production of ornamental stitch patterns.
