    摘要： A sewing machine with a pair of feed wheels which clamp a workpiece therebetween to transport the workpiece, the sewing machine comprising first and second feed shafts each of which have a clutch portion at an end thereof in opposition to each other and a group of gears disposed between these feed shafts for rotating the second shaft in the direction reverse to the rotational direction of the first shaft. The direction of transportation of the workpiece is changed by means of a clutch having a portion which selectively contacts the clutch portion of either the first or second feed wheel.

    摘要： A feed gear of a sewing machine for reversibly driving a rotary feed dog, as for example, a conveyor belt, a chain or a feed wheel, having a first gear part for producing an oscillating movement, and a second gear part for converting the oscillating movements into reversible intermittent rotary movements. The second gear part is provided with oppositely arranged driven one-way couplings.

    摘要： A mechanism for shifting the work clamp of a buttonhole sewing machine relatively to the stitch forming mechanism back and forth along the length of the buttonhole in which the mechanism comprises a screw associated with the work clamp and in engagement with threads on a belt pulley constrained in the machine frame. The pulley is driven by an endless flexible belt that is turned intermittently by an oscillating belt gripper. The length of the active stroke of the belt gripper, as well as the phase relationship of the active and inactive strokes thereof, may be changed to influence the stitch density and the direction of feed of the work clamp.
