Arrangement for the transfer of conveyed articles between intersecting trackways

摘要

This invention relates to an arrangement for engaging the relative elevation of two intersecting trackways for conveying and transferring freight goods in two conveying directions. One of the conveyors has rollers for engaging the flat bottoms of the freight bins and the other has flat tracks for receiving the wheels which project a short distance below the bottoms of the bins. The flat tracks are disposed at an elevation which is high enough to use the flat bottoms of the bins to clear the rollers in the intersecting conveyor. The portion of the tracks which intersects the roller conveyor is movable downwardly on eccentric cams a sufficient distance to drop the bins on the rollers to accomplish the transfer. Raising the flat track portion on the cams accomplishes transfer in the opposite direction.
