ABSTRACT:
A radially facing circumferential surface of a cam, in at least some planes which radiate from the cam axis, includes lines which are inclined relative to the cam axis. The inclinations of these lines vary from one axial plane to another, except in the dwell regions of the cam. A wobble member is supported for oscillating movement about a wobble axis. One or more cam followers on the wobble member engage the cam on opposite sides of a transverse reference plane which is substantially perpendicular to the cam axis. During operation of the mechanism, the cam turns about its axis, and the wobble member oscillates about its axis. The mechanism is used in a sewing machine to move a looper.
