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