Abstract
A mechanism for lifting from an operating position, inverting, and returning to the operating position a workpiece. The mechanism includes two drive devices, a linear drive which provides a continuous lifting force to a vertically movable member, and rotary drive which is energized to lift, invert, and lower a workpiece. The vertically movable member carries a rotational support member, which includes a rotatable shaft from which is supported the workpiece. The vertically movable member is raised, rotated and lowered by the rotary drive through a pair of levers, a first one of which is connected to rotate with the rotatable shaft and the second one of which is connected to be rotated by the rotary drive. Rotation of the second lever is imparted to the first lever through a cam and cam follower arrangement, the cam being provided on one of the levers and the cam follower on the other lever.
