ABSTRACT APPARATUS FOR LOADING AND/OR UNLOADING INDUSTRIAL PRESSES Work-handling apparatus, such as may be used in automatically loading and unloading a press in the manufacture of metal pressings, is arranged to reciprocate a work-handling attachment substantially linearly. The attachment is pivotally mounted on a crank lever, which is pivotally mounted on a crank arm, which is pivotally mounted on mounting means, the pivot axes of the crank arm and the attachment being substantially equi-distant from that of the crank lever. By means of geared connec- tions between the mounting means and the crank lever (in the ratio of substantially 2:1), and between the crank arm and the attachment (in the ratio of substantially 1:2) the attachment is caused to maintain a substantially constant orientation during linear movement resulting from the coordinated rotations of the crank lever and the crank arm.
