Abstract
An apparatus for destroying articles that has a cutter rotatably mounted adjacent a feed opening of a chamber containing articles to be destroyed. A ram is mounted in the chamber and is movable in a first direction toward the cutter. A plate forms the bottom surface of the chamber, and the plate has a plurality of grooves extending in the first direction. A wiper is mounted on the front of the ram, and the wiper has a plurality of teeth located in respective grooves in the plate. Thus, the plurality of teeth in the grooves prevent articles from sliding beneath the ram as it pushes articles into the cutter. In another embodiment, a segmented wiper is mounted on a first side wall, the segmented wiper has a length extending across an irregular upper surface of the ram, the segmented wiper further has a plurality of independently movable wiper teeth that are in substantially continuous contact with the irregular upper surface of the ram. Thus, the segmented wiper prevents articles from sliding between the irregular upper surface of the ram and the first side wall as the ram pushes articles into the cutter.
