Ash removal system

Claim 2

In an incinerator for the disposal of waste material by oxidation a closed casing defining a substantially airtight combustion chamber, means for feeding waste into said combustion chamber, means for subjecting said waste to a process of combustion, a holding means for residue from the combustion of said waste comprising an ash holding chamber at the bottom of the combustion chamber lying contiguous therewith, and a floor for said holding chamber vertically movable to permit lowering thereof as ash build-up on said floor develops whereby the floor may be lowered an amount commensurate with the ash deposits thereon to provide the combustion chamber with a constant volume.

Claim 3

An incinerator for the disposal of waste by combustion having a closed casing defining a substantially airtight combustion chamber, means for feeding waste material into said combustion chamber, an exhaust port for the exhaust of the products of combustion therefrom, a holding means for residue from the combustion of said waster comprising an ash holding chamber at the bottom of the combustion chamber lying contiguous therewith, a floor for said ash holding chamber vertically movable with respect to the incinerator casing adapted to simultaneously comprise a floor for the incinerator chamber and the ash holding chamber, and means for lowering said floor into the ash holding chamber whereby the surface thereof may be maintained constant to provide the combustion chamber with a constant volume.

Claim 4

An incinerator for the disposal of waste by combustion having a closed casing defining a substantially airtight combustion chamber, means for feeding waste material into said combustion chamber, an exhaust port for the exhaust of the products of combustion therefrom, a holding means for residue from the combustion of said waster comprising an ash holding chamber at the bottom of the combustion chamber lying contiguous therewith, a floor for said ash holding chamber vertically movable with respect to the incinerator casing adapted to simultaneously comprise a floor for the incinerator chamber and the ash holding chamber, and means for lowering said floor into the ash holding chamber whereby the surface thereof may be maintained constant to provide the combustion chamber with a constant volume.

Claim 5

An incinerator for the disposal of waste by combustion as defined in claim 2 including means for the supply of oxygen to the combustion chamber independent from the movable floor for the ash holding chamber to permit lowering said floor with respect to the oxygen supply means for the combustion chamber.

Claim 6

An incinerator for the disposal of waste by combustion as defined in claim 3 wherein the means for the supply of oxygen to the combustion chamber comprises an apertured tube extending longitudinally along the edge of the movable floor.

Claim 7

An incinerator for the disposal of waste by combustion as defined in claim 4 wherein the means for the supply of oxygen to the combustion chamber comprises an apertured tube lying on each side of the incinerator chamber.

Claim 8

An incinerator for the disposal of waste by combustion as defined in claim 5 wherein oxygen supply tubes on opposite sides of the incinerator chamber are laterally adjacent and independent from the movable floor for the ash holding chamber.

Claim 9

An incinerator for the disposal of waste by combustion as defined in claim 6 wherein the ash holding chamber subjacent the combustion chamber has vertical walls that provide for constant clearance around the movable floor as said floor is lowered into the ash holding chamber.

Claim 10

An incinerator for the disposal of waste matter by combustion as defined in claim 2 wherein the means for lowering the floor into the ash holding chamber lies intermediate oxygen supply pipes at opposite sides of the incinerator casing.
