  • Patent number: 6045295
    Abstract: In the operation of a landfill compactor, it is a common problem for the wheels to pick up debris, especially wire and cable, and carry it around with the wheels as they rotate. When the debris falls from the wheels in the direction toward the frame and the axles, it becomes packed between the frame and the axle hampering machine operation and requiring hours of corrective maintenance. The apparatus of the subject invention for inhibiting the wrapping of debris about the axle assembly provides a hook member to ensnare debris. As the wheel rotates, the debris picked up by the hook member is dragged across a serrated blade portion mounted on the axle assembly to pull apart the debris and thus prevent the debris from wrapping around the axle assembly.

  • Patent number: 4421435
    Abstract: The present invention relates to a method and apparatus for applying a thin film of a liquid to a vibratory plate arranged on an edge of a vibratory compactor. The apparatus for applying the thin film of liquid includes a container assembly for holding the liquid adjacent the plate. Liquid is preferably supplied to the container assembly under the influence of gravity. An element for maintaining intimate contact between a thin liquid film and a front surface of the plate as the thin film moves downwardly along the plate surface is arranged within a lower portion of the container assembly. The element is arranged adjacent to an outlet from the container provided along substantially the entire width of the front plate. The thin liquid film flows from the container as a low velocity laminar flow along the surface of the plate in the form of a liquid sheet. The liquid remains in contact with the plate surface due primarily to surface tension as the liquid moves downwardly.
