Abstract

Abstract Apparatus for the stacking and withdrawal of horizontal rods, comprising a plurality of horizontally aligned finger bars for supporting the rods in horizontal relation, each of the finger bars having a free end, a conveyor for receiving a rod in the horizontal position and for moving it vertically to a position adjacent the free ends of selected bars and a pair of screw conveyors in horizontal alignment that are movable upwardly for engaging the rod and for moving it laterally onto the selected bars. The conveyors cooperate with spacing combs on the bars which maintain the rods in a predetermined spaced relation on the bars when the conveyors are moved away from the bars.
