Link 1, designed as a bent lever, turns about fixed axis A and is connected by turning pairs B and E to pulley 3 and to link 4. Flexible link 8 runs over pulleys 3 and 7, of equal diameter, and is connected by turning pair G to link 2. Pulley 7 is rigidly attached to the base. Link 4, designed as a bent lever, is connected by turning pairs D and F to links 6 and 2. Link 5 is connected by turning pairs C and B to links 6 and 1. When link 1 turns about axis A, links 2, 4, 5 and 6 have complex motions.
