Link 1, designed as a complex lever, is connected by turning pairs A and B to pulleys 2 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 3 is connected by turning pairs C and D to flexible link 8 and to links 4 and 5. Links 4 and 6 are connected by turning pairs G and F to link 1. Links 5 and 6 are connected together by turning pair E. 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.
