ABSTRACT:
A lock stitch machine capable of being selectively set for either an overcasting mode or a hemming mode. A needle plate tongue is shifted between an operative position and an inoperative position in a region separated from the operating region of the looper, along a path substantially resembling a circular arc for a vertical displacement and a horizontal displacement greater than the vertical displacement, by turning an overcasting width adjusting knob which turns a control shaft. Thus, the needle plate tongue can be shifted between the operative position and the inoperative position regardless of the position of the looper thereby facilitating the stitching mode changing operation.
