Abstract: A hollow generally circular horizontal float body is provided. The body tapers in thickness from its central portion of its outer periphery and includes upper and lower walls which are inclined downwardly and upwardly, respectively, from the central portion to the outer periphery of the body. A horizontal work platform is spaced above the body and supported therefrom by upstanding supports extending and secured between the body and the platform at points spaced about the central portion of the body. The body includes a central vertical passage therethrough and the interior of the body spaced outwardly of and about the central portion includes structure defining ballast tanks which may be selectively flooded and evacuated of water.

Abstract: An upstanding panel member is provided having an opening formed therethrough in an upper portion thereof for snugly, but slidingly receiving the rear end portion of a cylindrical grease gun body therethrough. An elongated lever is hingedly supported, intermediate its opposite ends, from one side of the panel member for oscillation about an axis extending transversely of the lever, spaced outwardly of the opening and disposed generally normal to a line extending between the axis and the center of the opening. One end portion of the lever extends toward and projects slightly into the adjacent portion of the opening when that end portion of the lever is disposed at least generally normal to the center line of the opening and the other end of the lever is spaced outward from the panel member and swingable theretoward in order to swing the first mentioned end portion of the lever away from the panel member and to thus retract the free terminal end thereof away from the opening.
