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