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. When it is desired to move the transfer fingers from the fixed bed to the bolster, the transfer rails are moved in the direction of the bolster moving the transfer fingers along the shaft and onto the bolster. A lock is provided which attaches the transfer fingers to the bolster and the rails are moved toward the fixed bed. 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.
