  • Magnetic carrier
    Patent number: 6168221
    Abstract: A magnetic carrier includes a housing having an interior ledge. First and second levers are pivotally mounted within the housing such that the ledge limits the angular position of the levers with respect to the housing. First and second permanent magnets are connected with the respective first and second levers for attracting a workpiece. A pneumatic piston actuator is provided on the housing for pivoting the levers with respect to the housing to selectively pivot the magnets into and out of magnetic engagement with the workpiece.

  • Magnetic holding device
    Patent number: 6086125
    Abstract: A magnetic holding device includes a hollow cylinder having an axis and closed ends. A rodless piston having an elongated radial cross-section is slidable within the cylinder for movement between the ends. At least one 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.
