Link 1, designed as a complex lever, turns about fixed axis A and is connected by turning pairs C, E and F to link 4 and to pulleys 6 and 2, of equal diameter. Flexible link 7 runs over the pulleys and is connected by turning pair G to link 3. Link 5 turns about fixed axis B and is connected by turning pairs D to links 4 and 3. When link 1 turns about axis A, links 3 and 4 have complex motions and link 5 oscillates about axis B.
