Plate cam 1 rotates about fixed axis A and has two contours (working surfaces) a and b. Followers 2 and 3 oscillate about fixed axis B and have knife-edges c and d which slide along contours b and a. Links 4 and 5 are connected by turning pairs D and E to followers 3 and 2, and by turning pair C to each other. The lengths of the links comply with the conditions: B͞D=B͞E and C͞D=C͞E. By proper design of contours a and b of cam 1, point C can be made to trace a specified path. Knife-edges c and d are held in contact with contours b and a of cam 1 by spring 6.
