Pulleys 1 and 2 are of equal diameter, as are pulleys 4 and 5. Pulley 1 rotates about fixed axis A and, through flexible link 6, rotates pulley 2 about fixed axis B. Link 3, designed as a bent lever, is connected by turning pair C to flexible link 6 and by turning pairs D and E to pulleys 4 and 5. Flexible link 7 runs over pulleys 4 and 5 and oscillates about fixed axis F. When pulley 1 rotates about axis A, pulleys 4 and 5 roll along flexible link 7, imparing a complex motion to link 3.
