Abstract

A Body Waste Disposal (liquid) System which makes disposition of the fluid by burning in the combustion chamber of the associated internal combustion Engine. It consists of a receptacle, small reservoir, metering valve and connecting hose. The vaccuum in the intake manifold of the Engine draws the fluid into the Combustion chamber where it is burned by the heat of combustion of the fuel.

1 Claim, 1 Drawing Figure PAIENTEDSEPI H978 EDWARD HOWA 5 LIQUID BODY WASTE DISPOSAL SYSTEM BRIEF SUMMARY OF INVENTION The liquid body waste disposal system is designed to accept and dispose of liquid body waste when installed in vehicles such as boats, trailers, campers, trucks and aircrafts employing or using an internal combustion engine having an intake manifold to provide a vaccuum source.

The drawing illustrates an installation for front and rear seat passengers in a typfiical automobile.

The object of the liquid body waste disposal system is to accept and dispose of liquid body waste cleanly and completely without the aid of moving parts or an external power source. The system is composed of three primary components, appropriate hoses or tubing and fittings wherein the components are connected to the intake manifold of an internal combustion engine.

DETAIL DESCRIPTION OF THE INVENTION With reference directed to the drawing, the liquid body waste disposal system 12 with the present invention is herein illustrated as adpated for use with an automaobile A having seats S (rear seat not shown) and which includes a source of power such as an internal combustion engine E with the usual intake manifold associated therewith.

As will be understood, the intake manifold of the internal combustion engine B provides a vaccuum source. The primary components of the sytem as shown in its present form are a pair of oval shaped funnel type urinals 18 and 18 one for the front compartment and one for the rear compartment of the automobile A, respectively. The urinals 18, 18' are connected by front and rear hoses 17 and 17 to a T-shaped inlet fitting 16.

The inlet fitting 16 connects to a reservoir or plastic tank 14 located on the underside of the floor 10 of the automobile A. The urinals 18, 18' are maintained in a storaged position with the aid of front and rear retainers 20 and 20' respectively.

OPERATION The system 12 is on at all times when the engine E is operating. The vacuum taken from the intake manifold causes a continous airflow from the urinals 18, 18' through the reservoir 14 and by way of the metering valve 26 into the intake manifold and thus into the combustion chambers where it is burned and passed out through the engine exhaust system (not shown).-

Metering valve 26 has a handle or valve control knob 27 whereby the rate of flow of liquid therethrough may be optimized; otherwise, no controls of any kinde are required.

The user pulls the urinal 18 or 18, depending upon whether he or she is in the front or rear compartment of the automobile A, out to a convenient position and deposits the liquid body waste therein. The liquid L flows by gravity, aided by the engine vaccuum, into the reservoir 14. Reservoir 14 is evacuated through the outlet pipe 22 by way of the hose or tubing 24 by the engine vaccuum drawing it into the intake manifold. The hose or tubing 24 is connected to the intake manifold with an intake manifold fitting 28. The liquid waste is thus destroyed by the high temperature of the associated combustion chambers.

What is claimed is:

l. A liquid body waste disposal system for use in a conveyance or vehicle with an internal combustion engine comprising an oval shaped funnel type urinal, a plastic tank-like reservoir beneath the vehicle, said internal combustion engine characterized by an intake manifold having a vaccuum source, said urinal adapted to be connected to the reservoir, a metering valve interposed between the reservoir and the intake manifold, said liquid waste from the urinal is deposited in said reservoir and drawn from said reservoir through said metering valve to said intake manifold by said vaccuum source, whereby said liquid waste is burned by the heat of combustion associated with said intake manifold.
