Flexible link 1 runs over pulleys 2 and 5, of equal diameter, and oscillates about fixed axis A. Link 4 is connected by turning pairs D and C to pulleys 2 and 5. Flexible link 1 is connected by turning pair E to link 3 which turns about fixed axis B. When flexible link 1 turns about axis A, link 4 has a complex motion and link 3 oscillates about axis B.
