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