Link 3 is reciprocated by the slider-crank linkage CDB. Link 3 is connected by turning pairs A and B to wheels a which roll without slipping along plane b. Flexible link d runs over pulleys b which rotate freely on axes A and B. Flexible link d is driven by slider-crank linkage EFG which is connected by turning pair G to link d. When cranks 1 and 2, connected together by meshing gears 4 and 5, rotate about fixed axes C and E, point e of flexible link d reciprocates, participating in two motions: the motion of link 3 and the relative motion of flexible link d with respect to link 3.
