Link 1 rotates about fixed axis z-z and is connected by a screw pair to link 2. Link 1 has pulley d on which a rope is wound. When branch a of the rope is pulled, link 2 moves downward; when branch b is pulled, it moves upward. Link 2 is connected by turning pair A to link 3 which, in turn, is connected by turning pairs B and C to links 5 and 4. Link 4 turns about fixed axis E. Link 5 has piston f sliding in cylinder 6 which turns about fixed axis F. When branches a and b of the rope are alternately pulled, piston f reciprocates in cylinder 6.
