When link 1 rotates about fixed axis A, slotted link 3 oscillates about fixed axis C. The axis of slider 2 does not pass through centre C of slotted link oscillation. The angle β of oscillation is determined by the equation β„•=arcsin((A͞B-C͞D)/A͞C)+arcsin((A͞B+C͞D)/A͞C) where C͞D=e is the distance between the axis of slotted link 3 and axis C
