Plate cam 1 rotates about fixed axis A. Follower 4 oscillates about fixed axis B and carries roller 5 which rolls along the working surface of cam 1. Follower 4 has screw 3 which is connected by a screw pair to slider 6. Link 7 is connected by turning pairs C and E to slider 6 and to driven slide 2 which reciprocates in fixed guide D. By means of screw 3, axis C of slider 6 can be adjusted along follower 4 with respect to axis B and clamped in the required position, thereby varying the type of motion of slide 2.
