Pulleys 2 and 5 are of equal diameter, as are pulleys 4 and 8. Link 1, designed as a bent lever, is connected by turning pairs A and B to pulleys 2 and 5 and by turning pair D to flexible link 7 which runs over pulleys 4 and 8. Flexible link 6 runs over pulleys 2 and 5 and is rigidly secured at points G and F to the base. Link 3 is connected by turning pairs E and C to pulleys 8 and 4. Flexible link 6 is connected by turning pair C to pulley 4. When link 1 has straight translational motion, pulleys 2 and 5 roll along flexible link 6 and pulleys 4 and 8 rotate about axes C and E, imparting complex motion to link 3.
