  • Patent number: 6618873
    Abstract: A waste disposer assist tool for automatically feeding waste food contained within the housing of a standard kitchen electric food disposer and for spraying liquid soap. The tool includes a hollow handle and a piston which screw together through a central hole of a flexible plunger. The plunger is held between respective flanges ofthe handle and the piston with the piston slightly protruding from within the plunger. The tool is positioned over the opening of the sink above the garbage disposer with the piston fitted within and in a substantially air-tight seal with the interior of the housing of the disposer unit. The plunger fits in a substantially air-tight seal against the bottom interior of the sink. The slight vacuum created by the outflow of ground food waste and water by the garbage disposer blades below the piston causes the higher ambient pressure against the upper side of the plunger to force the piston downward against he waste food in an automatic feed fashion.

  • Patent number: 6557791
    Abstract: A plant waste disposal system is further includes a wood chipper apparatus having plant waste fragmenting elements and having a plant waste receiving hopper; an elongate push member having a member first end for gripping by hand and having a member second end of at least twice the width of the member first end for abutting and pushing plant waste into the plant waste receiving hopper. The elongate push member preferably is formed of tool material which is biodegradable. The elongate member preferably is constructed to fracture when subjected to tensile force in excess of five pounds, for preventing the elongate member from pulling a worker hand into the plant waste fragmenting elements.
