  • Patent number: 4138331
    Abstract: A method of incinerating toilet waste comprising applying combustion heat in substantially the manner of applying heat to the bottom of a cooking pot under and to and through the bottom of a heat permeable upwardly opening receptacle containing the waste and thereby effecting substantial boiling and incineration of the waste, supplying preheated air into the receptacle, and compelling vapor and products of combustion generated by the combustion heat to pass from the receptacle into a combustion zone under the receptacle and through the combustion heat and into an after burner flue leading from the combustion chamber. An aesthetically desirable and sanitary masking foam may be applied to the surface of accumulated toilet waste in the receptacle prior to boiling and incineration.

  • Patent number: 4051561
    Abstract: A store and burn incinerating toilet has a heat permeable upwardly opening receptacle over a combustion chamber and under a deck providing a toilet seat support and having a receiving opening over the receptacle, the opening being closeable by a removable plug closure when a selectively operable heat producing device in the combustion chamber is in operation. Vapor and products of combustion generated in the receptacle pass from the receptacle into the front portion of the combustion chamber and toward the rear of the chamber and into an afterburner flue stack leading from the rear of the chamber. Preheated air is introduced into the receptacle during the burn cycle, and air is also introduced at the lower end of the stack. While incineration is in progress the closure is locked by a thermally responsive safety-locking device. During the accumulating and storing interval, a layer of masking foam may be applied and maintained over the waste in the receptacle.
