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