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