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