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