Cylindrical ridge cam 1 rotates about fixed axis A and has profiled ridge a. Follower 2 is connected by turning pair B to crosspiece 9 which carries two rollers 3, rolling along the side surfaces of ridge a. The lower end of follower 2 is collar b which encircles round eccentric 4. Eccentric 4 rotates about fixed axis D and is rigidly attached to worm wheel 8 which meshes with worm 7. Gear 5, rigidly attached to cam 1, meshes with gear 6 which is rigidly attached to worm 7 and rotates with it about fixed axis C. When cam 1 rotates, follower 2 has a complex motion.
