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