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