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