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