Abstract
A sewing machine, has a looper mounted (at 96) on a bearing member (82) and has a looper drive assembly (20) including a rotary shaft (28) and a crank pin (34) obliquely mounted thereon. Rotational and axial movements are imparted to the looper via the member (82) by motion transfer means (60) driven off the crank pin (34). Manual adjustment means (110) are provided to change the relative working association between the crank pin (34) and the motion transfer means (60) so as to vary the motion of the looper. <IMAGE>
