ABSTRACT:
A zig-zag stitch sewing machine having a laterally displaceable needle, the displacements of the needle being controlled by a cam arrangement through a linkage mechanism, the cam arrangement being actuated by one or more control members, the linkage arrangement including a pivotally mounted slider, the pivotal axis for the slider being provided on a pivotal lever so that the pivotal axis is displaceable, and a connecting rod which is pivotally connected to the mounting for the needle, the connecting rod being displaceable along the slider, means being provided for displacing the pivotal axis of the slider while its free end is immobilized in one of its terminal angular positions, whereby displacement of the end of the connecting rod along the slider causes a needle carrying bar to be displaced between two terminal decentered positions.
