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