ABSTRACT:
Apparatus for handling material by magnetic attraction comprising an elongated tubular member of nonmagnetic material with a magnet slidably received in the tubular member. The magnet is movable along the length of the tubular member between starting and dwell positions to carry magnetically attractive articles or material along the tubular member. A nonmagnetic barrier engages the tubular member between the starting and dwell positions to prevent the articles or material attracted by the magnets from moving past the position of the barrier as the magnet moves past the barrier to the dwell position.
