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