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