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