ABSTRACT:
A waste disposal apparatus has a cutter apparatus with angled teeth. The cutters may be disposed in a passage of a housing having an inlet and an outlet. The cutter apparatus has a stationary cutter and a pivoting cutter which pivots with respect to the stationary cutter. The stationary cutter has a plurality of teeth intermeshing with a plurality of teeth on the secondary cutter as the secondary cutter pivots. The teeth of the stationary and pivoting cutters have edges that extend towards one another at an angle with respect to a traverse direction perpendicular to a longitudinal axis such that the teeth meet at an angle. Each edge has a leading edge which meets first to concentrate cutting force at a point along the edge. The force moves along the edge from the leading edge to a trailing edge. A drive means rotates the pivoting cutter. The waste disposal apparatus may be a water powered waste disposal apparatus. The drive means may have a housing defining an annular chamber with a drive piston slidingly disposed therein and coupled to the pivoting cutter.
