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