Shifting apparatus for use in a transfer press having moving die bolsters. The shifting apparatus includes transfer rail sets that are located on the bolster and on the fixed bed that are interconnected during the normal transfer of the work pieces between dies. Transfer fingers are carried by both transfer rail sets that serve to engage the work pieces and move the work pieces through the positions of the transfer press. Transfer finger shift apparatus extends between the two rail sets and includes a shaft carrying a shift base member which has transfer fingers connected thereto. An elevating device is provided on the fixed bed to raise the transfer fingers sufficiently to pass over the top of the transfer fingers located on the bolster. A piston rod, which is secured to the transfer fingers, is retracted into an air cylinder which is attached to the transfer rail set of the bolster, causing the transfer fingers to move from the fixed bed to the bolster. The rails are separated and the bolster is moved to a remote location away from the press for replacement of the dies and related transfer fingers.
