Pulleys 1 and 6 are of equal diameter. Pulley 1 rotates about fixed axis A and, through flexible link 7, rotates pulley 6 about fixed axis B. Link 3, designed as a bent lever, is connected by turning pairs F, G and H to links 2, 4 and 5. Links 2 and 4 are connected by turning pairs D and E to flexible link 7. Link 5 turns about fixed axis C. When pulley 1 rotates about axis A, links 2, 3 and 4 have complex motions and link 5 oscillates about axis C.
