Crank 1 rotates about fixed axis C and is connected by turning pair D to link 5 which, in turn, is connected by turning pair E to rocker arm 4. Rocker arm 4 turns about fixed axis A and is connected by turning pair F to sliding lever 3 which moves in slider 6. Slider 6 turns about fixed axis K. Lever 3 has gear segment a which meshes with pinion 2. Pinion 2 turns about axis B of rocker arm 4. When crank 1 rotates at uniform velocity, gear 2 rotates at nonuniform velocity and its complex motion is determined by the dimensions of the links.
