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