ABSTRACT:
A shaft coupling mechanism for a sewing machine includes an eccentric secured on a rotatable shaft and includes a ring engaged on the eccentric so as to be moved up and down by the eccentric. The ring has a downward extending bar. A block is rotatably secured to the lower end of the bar and rotatable relative to the bar about a pin. The block includes a rod secured to a spindle so as to rotate the spindle in an oscillating action without a ball joint. The rotational movement of the block relative to the bar will not affect the movement of the bar.
