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