Abstract
Abstract A toilet of the incinerating type includes several pots which are set on a turntable at equal angular intervals, with one of the pots ready for use at all times. A pot containing human waste is automatically connected to an incinerator for incineration of the waste, and the other empty pots are automatically moved to a desired position ready for use and a position waiting for use.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
197 words
A toilet of the incineration type, said toilet comprising: a turntable mounted for rotation about an axis; a plurality of waste receiving pots removably mounted on said turntable at equal angular intervals about said axis; means for rotating said turntable about said axis to selectively align each of said pots at predetermined positions including a waste receiving position and an incineration position; an incinerator located to confront one of said pots aligned at said incineration position; means for removing said one pot from said turntable and tightly joining said one pot to said incinerator, such that the interiors of said one pot and said incinerator form an enclosed chamber; means for jetting combustion gas into said chamber to thereby incinerate waste contained in said one pot; stirring means extending into said chamber for stirring and kneading said waste during incineration; means for discharging exhaust gas from said chamber during said incineration; and means for circulating cooling air around the exterior surfaces of said incinerator and said one pot during said incineration to thereby cool said exterior surfaces, and for then mixing said cooling air with said exhaust gas to thereby reduce the temperature of said exhaust gas.
Claim 2
Dependent Claim
197 words
A toilet of the incineration type, said toilet comprising: a turntable mounted for rotation about an axis; a plurality of waste receiving pots removably mounted on said turntable at equal angular intervals about said axis; means for rotating said turntable about said axis to selectively align each of said pots at predetermined positions including a waste receiving position and an incineration position; an incinerator located to confront one of said pots aligned at said incineration position; means for removing said one pot from said turntable and tightly joining said one pot to said incinerator, such that the interiors of said one pot and said incinerator form an enclosed chamber; means for jetting combustion gas into said chamber to thereby incinerate waste contained in said one pot; stirring means extending into said chamber for stirring and kneading said waste during incineration; means for discharging exhaust gas from said chamber during said incineration; and means for circulating cooling air around the exterior surfaces of said incinerator and said one pot during said incineration to thereby cool said exterior surfaces, and for then mixing said cooling air with said exhaust gas to thereby reduce the temperature of said exhaust gas.
Claim 3
Dependent Claim
18 words
A toilet as claimed in claim 1, wherein said turntable is mounted for rotation about a vertical axis.
Claim 4
Dependent Claim
35 words
A toilet as claimed in claim 2, wherein said incinerator is positioned above said turntable and has an open bottom portion, and each said pot has an open top portion and an exterior annular flange.
Claim 5
Dependent Claim
47 words
A toilet as claimed in claim 3, wherein said removing means comprises means for contacting the bottom of said flange of said one pot and for thereby raising said pot from said turntable until said flange is in tight contact with the lower end of said incinerator.
Claim 6
Dependent Claim
52 words
A toilet as claimed in claim 4, wherein said contacting and raising means comprises plural vertically movable rods, each said rod having at a lower position thereof a hanging member adapted to contact the bottom of said flange, and means for moving said rods, said hanging members and said one pot upwardly.
Claim 7
Dependent Claim
34 words
A toilet as claimed in claim 5, wherein said moving means comprises a rack on each said rod, a pinion mounted in engagement with each said rack, and a motor for driving said pinions.
Claim 8
Dependent Claim
37 words
A toilet as claimed in claim 1, wherein said jetting means extends through said incinerator into said chamber, said jetting means further comprising means for jetting cooling air into said chamber after the completion of said incineration.
Claim 9
Dependent Claim
19 words
A toilet as claimed in claim 2, wherein said discharging means comprises an exhaust pipe extending from said incinerator.
Claim 10
Dependent Claim
88 words
A toilet as claimed in claim 8, wherein said circulating means comprises a cooling chamber surrounding said incinerator and said one pot, and a cooling passage extending from said cooling chamber and surrounding said exhaust pipe, the outer ends of said exhaust pipe and said cooling passage being of a construction to create a negative pressure in said cooling passage upon the discharge of exhaust gas from said outer end of said exhaust pipe, whereby said cooling air is drawn through said cooling chamber and said cooling passage.
Claim 11
Dependent Claim
34 words
A toilet as claimed in claim 9, wherein said mixing means comprises a primary mixing chamber positioned to receive said exhaust gas from said exhaust pipe and said cooling air from said cooling passage.
Claim 12
Dependent Claim
51 words
A toilet as claimed in claim 10, further comprising a secondary mixing chamber positioned to receive the mixture of exhaust gas and cooling air from said primary mixing chamber, and means for mixing additional cooling air with said mixture in said secondary mixing chamber, to thereby further cool said exhaust gas.
Claim 13
Dependent Claim
18 words
A toilet as claimed in claim 11, wherein said additional cooling air mixing means comprises a cooling fan.
Claim 14
Dependent Claim
18 words
A toilet as claimed in claim 1, wherein said stirring means comprises an agitator extending through said incinerator.
