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