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