Appl. No.:

7/553353

Inventors:

Charles L. Sargent - Ann Arbor MI
John M. Antos - Ann Arbor MI
Scott I. Biba - Ann Arbor MI

Assignee:

Thetford Corporation - Ann Arbor MI

International Classification:

E03D 1100

US Classification:

4432

Abstract:

A portable toilet having a battery operated flushing assembly that is powered by batteries carried in the toilet. The batteries provide for a "pulsed" flushing action of the flush water and this is achieved by the use of an axial flow pump which is operable to lift small amounts of water small distances to the bowl in a repeatable fashion. This facilitates flushing of the toilet, makes it easier for the user to flush the toilet, and provides for efficient and complete flushing. A selectively operable closure plate prevents leakage of water from the toilet bowl during transport of the toilet.
