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