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