ABSTRACT:
A sewing machine provides zigzag and feed drive features through operation of independent synchronized stepper motors. A first stepper motor imparts reciprocating motion to a first rack piece which is hingedly connected to a middle piece and a lever. The lever is connected to a needle supporting piece which imparts zigzag motion to a needle. A second stepper motor through a second rack piece imparts oscillating motion to a connecting rod. Shifting motion in a feeding device is provided by an axle which is powered by the oscillating connecting rod.
