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