Abstract The improved portable sewage disposal system of the invention includes a portable toilet, a sewage holding tank therefor, a tank drainage pipe, a tubular, preferably flexible, conduit connected to the drainage pipe and an adapter, preferably of molded plastic or rubber, inserted at one end in the conduit with the other reduced end thereof being externally threaded for releasable threaded engagement with a fixed sewage drain cleanout tee. The adapter system includes the conduit and adapter releasably inter-connected. Gripping means may be provided for releasably securing the conduit and adapter in gas-tight, liquidtight relation, and the adapter may have a shoulder which aids in positioning the conduit over the insert end thereof. The gripping means may include unidirectional serrations on the exterior surface of the insert end or a flexible collar or a releasable ring clamp. The described systems permit liquid- and gas-tight removal of sewage wastes from the portable holding tank into a fixed disposal drain cleanout tee in a rapid, simple and efficient manner.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
124 words
An adapter for coupling the flexible drain conduit of a portable sewage system in liquid- and gas-tight coupling relationship to a fixed sewage system via a cleanout tee thereof to permit the ready transfer of wastes from the portable system to the fixed system comprising: a generally cylindrical member having two opposed ends of different diameters, the smaller diameter end having an outer, externally threaded portion adapted to threadably engage the internally threaded opening of a conventional cleanout tee of the fixed sewage system, the larger diameter end having an unthreaded portion for releasably and slidably receiving the end of a flexible conduit comprising the outlet of the portable sewage system; and a tapered intermediate portion joining the two ends in a unitary structure.
Claim 2
Dependent Claim
124 words
An adapter for coupling the flexible drain conduit of a portable sewage system in liquid- and gas-tight coupling relationship to a fixed sewage system via a cleanout tee thereof to permit the ready transfer of wastes from the portable system to the fixed system comprising: a generally cylindrical member having two opposed ends of different diameters, the smaller diameter end having an outer, externally threaded portion adapted to threadably engage the internally threaded opening of a conventional cleanout tee of the fixed sewage system, the larger diameter end having an unthreaded portion for releasably and slidably receiving the end of a flexible conduit comprising the outlet of the portable sewage system; and a tapered intermediate portion joining the two ends in a unitary structure.
Claim 3
Dependent Claim
40 words
An adapter in accordance with claim 1 wherein the larger diameter end has an outer surface including a plurality of serrations angled toward the intermediate portion for facilitating the insertion of the adapter into the end of the flexible conduit.
Claim 4
Dependent Claim
23 words
An adapter in accordance with claim 1 further including an outwardly extending peripheral shoulder for abutting against the end of the flexible conduit.
