Feed bar advance and return driving apparatus for a transfer press. An upper slider is reciprocally vertically movable in the press crown in synchronization with the operation of the press, and a pinion rotatably mounted on the upper slider is rotated alternatingly in opposite directions with the upward and downward vertical movement of the upper slider. A drive rack vertically slidably supported on the upper slider is connected to the pinion at a position on the pinion which is eccentric to the axis of rotation of the pinion and is reciprocally vertically driven by the rotation of the pinion. The lower end of the drive rack extends downwardly and engages a drive pinion for rotating the drive pinion alternatingly in opposite directions during the reciprocal vertical motion of the drive rack. A drive lever connected to the drive pinion at a position eccentric to the axis of rotation of the drive pinion and pivotally mounted on the press is driven in a swinging motion and is connected to a lower slider for supporting feed bars of the press to drive the lower slider in advancing and returning directions.
