ABSTRACT:
A hand-operated or vehicle-supported magnetic sweeper has a longitudinally elongated, hollow magnet-containing body member preferably formed in one piece of non-magnetic material which may include wheels mounted on its ends and a handle socket disposed centrally between the ends of the body member for reception of a handle member for hand operation of the sweeper over a floor surface. A rigid top cover plate is secured to the body member to cover and enclose the magnets contained in the hollow body and to provide rigidity to the sweeper construction. A catcher member formed of non-magnetic material is removably mounted on the body member so that metallic objects attracted to the magnet-containing body member are captured against the surface of the overlying catcher member and retained thereagainst until the catcher member is manually removed, whereupon the metal objects will simply fall away for discard. Wider magnetic sweeper units may be formed simply by securing individual body members together in end-to-end relationship by using longer, interconnecting top cover plates.
