Link 1, designed as a complex lever, is connected by turning pairs A and B to pulleys 7 and 2, of equal diameter, an by turning pairs H and G to links 6 and 4. 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, is connected by turning pairs E and D to link 5 and to link 3 which turns about fixed axis C. Links 6 and 5 are connected together by turning pair F. When link 1 has straight translational motion, pulleys 2 and 7 roll along flexible link 8, imparting complex motions to links 4, 5 and 6, and link 3 oscillates about axis C.
