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