Link 1, designed as a bent lever, turns about fixed axis A and is connected by turning pairs D and E to pulleys 2 and 3, of equal diameter. Flexible link 7 runs over the pulleys and is connected by turning pairs G to links 4 and 5. Link 4 turns about fixed axis B. Link 6 turns about fixed axis C and is connected by turning pair F to link 5. When link 1 turns about axis A, link 5 has a complex motion and links 4 and 6 oscillate about axes B and C.
