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