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