ABSTRACT:
An overlock sewing machine is provided with means for driving a lower looper according to a plurality of different oscillational movements independently of each other, a clutch mechanism for changing the aforementioned movements from one to the other mode, a back and forth drive mechanism for moving a lower looper back and forth, a mechanism for transmitting movement of the back and forth drive mechanism to a lower looper and releasing transmission of the movement therefrom, a lower looper oscillating means for oscillatively moving a lower looper, a mechanism for releasing oscillational movement of the upper looper therefrom, and a motion change-over device for interchanging operation between the clutch mechanism, the transmission and release means, and oscillational movement release means. The arrangement permits conversion of various stitch formations in a sewing machine to take place in a simple manner without requiring complicated adjustment.
