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