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