Abstract

A dual cylinder pivotal work piece holding device includes a fixture pivotally mounted on a frame. A crank arm drives the fixture about a pivot axis. First and second cylinders have rods pivotally connected to the crank arm at a drive point offset from the fixture pivot axis. The rods form an oblique angle with each other and a controller is provided for extending and retracting the rods in a coordinated cycle so that at least one of the rods is moving at any instant during rotation of the fixture.
