  • Looptaker driving arrangement and method for zig-zag sewing machines
    Patent number: 5870960
    Abstract: A looptaker driving arrangement in a zig-zag sewing machine includes: a rotatable drive shaft driving rotation of the looptaker of the sewing machine; a main drive member rotatably supported on the drive shaft; a secondary drive member fixed on the drive shaft for concurrent rotation therewith; a bushing rotatably mounted on the drive shaft with an eccentric outer periphery; and a coupling member rotatably mounted on the periphery of the bushing in eccentric relation to the drive shaft and engaging the main drive member and the secondary drive member. Rotation of the main drive member about the drive shaft axis combined with rotation of the bushing about the drive shaft axis relative to the main drive member angularly accelerates and decelerates the secondary drive member with respect to the main drive member and, in turn, angularly accelerates and decelerates the drive shaft.
