ABSTRACT:
A workpiece transfer mechanism including a base having spaced parallel slides mounted in spaced parallel ways, bellcrank levers having their central portions pivotally mounted on the slides and having first portions pivotally mounting workpiece engaging members and having second portions connected by tie rods, with the force required to overcome the frictional engagement between the slides and the ways being greater than the force required to pivot the bellcrank levers, whereby the application of a unidirectional force to the tie rods will cause the workpiece engaging members to engage the workpiece prior to the time that the unidirectional force will cause the slides to move in the ways to transfer the workpiece from one position to another.
