Abstract
Abstract A container having a conventional toilet seat and cover, includes an inner rotating pan to catch waste, separate liquid, and after use to rotate to dump solid from the pan onto an incinerating hearth. The separated liquid flows into a jacket defining the firebox side wall for evaporating liquid during the incineration of the solids. The rotary pan is movable from a sealed position, which seals the fire chamber from the seat, to a rotating position spaced therefrom. Air is forced into the unit maintaining it under positive pressure and provide a positive circulation of air throughout the fire chamber. Solids are initially dried and incinerated on a solid hearth following one use cycle, and then are scraped onto a grill for open flame incineration following the next use cycle. Lifting and lowering the toilet seat activates the device.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
172 words
An incinerating toilet having an outer shell; an inner shell separated from said outer shell; a combustion chamber mounted in said inner shell including burner means at the bottom thereof; grate means mounted above said burner means; the wall of said combustion chamber being a hollow jacket for collecting and holding liquid and having upper vapor outlets; barrier means at the upper end of said combustion chamber having an opening therein; a waste catching and separating rotary pan mounted in the upper end of said combustion chamber below said barrier arranged to separate liquid waste on receipt and pass it in to said hollow jacket and to deposit solid waste on said grate on rotation of said rotor; said burner arranged at the bottom of said combustion chamber having peripheral flame means for heating said jacket and central flame means for heating solid waste on said grate means; seat and lid means positioned above said barrier; and means connecting said lid to said rotary pan means for rotating the same after use.
Claim 2
Dependent Claim

Claim 12
Dependent Claim
119 words
In an incinerating toilet having a combustion chamber for incinerating waste separated from a toilet seat by a barrier, the improvement of a multiple compartment waste catching and separating rotor mounted below said barrier and having circular end walls and including three separated compartments, there being a series of openings in the end wall for each compartment permitting separation of liquiD from solid therein; means for moving said rotor from a sealing position against said barrier; means for rotating said rotor to dump solid from said rotor and turn the used compartment into said combustion chamber when said rotor is spaced from said barrier; and means for moving said rotor into sealing position against said barrier after such rotation.
Claim 13
Dependent Claim
119 words
In an incinerating toilet having a combustion chamber for incinerating waste separated from a toilet seat by a barrier, the improvement of a multiple compartment waste catching and separating rotor mounted below said barrier and having circular end walls and including three separated compartments, there being a series of openings in the end wall for each compartment permitting separation of liquiD from solid therein; means for moving said rotor from a sealing position against said barrier; means for rotating said rotor to dump solid from said rotor and turn the used compartment into said combustion chamber when said rotor is spaced from said barrier; and means for moving said rotor into sealing position against said barrier after such rotation.
