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