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