Round pulley 1 rotates about fixed axis A. Flexible link 2 runs over pulley 1 and pulley 3 which rotates about axis B. Circular gear 4 is rigidly attached to pulley 3 and meshes with noncircular gear 5 which rotates about fixed axis C. Bent lever 6 turns about axis A and is connected by turning pair B to links 3 and 4, and by a sliding pair to slider 8. Slider 8 moves along slot a of lever 6 and is connected by turning pair D to rod 7 which slides in fixed guided b. When pulley 1 rotates, lever 6 oscillates and rod 7 correspondingly reciprocates in guide b. The kind of motion of lever 6 and rod 7 depends on the shape of the centrode of noncircular gear 5.
