Link 1 is connected by turninig pairs A and B to pulleys 6 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 5 is connected by turning pairs E and F to links 1 and 3. Link 3, designed as a bent lever, is connected by turning pairs G and H to links 2 and 4 which turn about fixed axes C and D. When link 1 has straight translational motion, links 3 and 5 have complex motions and links 2 and 4 oscillate about axes C and D.
