Abstract
A generally wedge-shaped mud box with a bottom wall has a mud outlet orifice through which mud will flow. An edge of the wedge-shaped box has a rectangularly shaped cover rotatably attached so as to be rotatable between an filling position and an operating position. A releasable biasing structure biases the cover toward a bottom wall of the box so as to force mud contained in the box toward the outlet orifice. A mud gun, including a hollow body with an inlet and an outlet orifice, is releasable attached to the outlet orifice of the box. When air under pressure is introduced into an air inlet of the gun, mud entering through the inlet orifice is forced out through the outlet orifice of the gun. A nozzle chassis is affixed to the gun with a plurality of different nozzles movably attached thereto, and each nozzle is movable between a stored and an aligned position so that only one nozzle of the plurality of nozzles is aligned with the outlet orifice of the gun at a time.
