Abstract
A transfer mechanism for transferring a large generally flat workpiece into and out of a power press, or between adjacent power presses, including a pair of spaced stands having respective gear boxes swingably mounted thereon with reversible drive means for oscillating the gear boxes in unison through 180.degree. from a first horizontal position downwardly and then upwardly to a second horizontal position with subsequent return along the same path to the first position. The gear boxes carry coaxial stubshafts with arms of equal length mounted thereon and with grippers at the ends of the arms for gripping the lateral edges of the workpiece. Each of the gear boxes has an input gear which is coaxial with the oscillation axis and anchored to the associated stand as well as an output gear which is connected to the associated stubshaft, the input gear being twice the diameter of the output gear and having the same directionality so that as the gear boxes are swung from first to second position the arms are swung from a first horizontal position to a second horizontal position extending in the opposite direction, the grippers being operated cyclically and in unison for gripping and depositing a workpiece.
