Link 1, designed as a bent lever, is connected by turning pairs A and B to pulleys 7 and 2, of equal diameter. Flexible link 8 runs over the pulleys and is rigidly secured at points H and K to the base. Link 3, designed as a bent lever, is connected by turning pair C to flexible link 8 and by turning pairs G and F to links 4 and 6. Link 5 is connected by turning pairs D and E to links 4 and 1 and to link 6. 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.
