Abstract: A fork extension attachment for a boom-type forklift for use in loading and unloading a fragile cargo from commercial containers includes an extension portion pivotally connected to the outer end of the boom to allow pivotal movement of the extension in a vertical plane and a fork assembly having its inner end pivotally connected to the outer end of the extension portion to allow pivotal movement of the fork assembly in a vertical plane. The fork assembly includes at least two tines that are mounted for powered horizontal lateral movement relative to each other and relative to the longitudinal axis of the assembly. An electrical pendulum switch is provided for maintaining the fork assembly in a substantially horizontal position when desired.

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.
