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