Link 2 has collar a encircling fixed eccentric b which has its centre at point A. Link 3 is connected by turning pairs B to connecting rod 5 and crank 4 of slider-crank linkage EBD. When link 2 rotates at uniform velocity about axis A, link 4 rotates about fixed axis E at nonuniform velocity, transmitting motion to slider 6 with different times for the forward and return strokes.
