Plate cam 1 rotates about fixed axis B. Follower 3 oscillates about fixed axis A and carries roller 4 which rolls along the working surface of cam 1. Link 5 is connected by turning pairs C and D to follower 3 and to driven slide 2 which reciprocates in fixed guide E. Bearing block a can be adjusted along guide b with respect to axis B and clamped in the required position. This adjustment varies the type of motion of slide 2.
