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