Abstract

A magnetic holding device includes a hollow cylinder having closed ends. A rodless piston is slidable within the cylinder for movement between the ends. A magnet is carried by the piston. The piston is driven back and forth in the cylinder by air pressure. The magnet is adapted to pick up a workpiece adjacent to one end of the cylinder when the piston is driven toward that end of the cylinder.
