Abstract
Abstract A combination fresh water supply and waste holding tank for use in mobile structures such as vehicles. The tank includes separate half shell portions and an extensible divider wall extending across the internal tank space between the half shell portions. A fresh water supply holding structure is provided in one portion of the shell spaces defined by the divider wall and a waste holding structure is provided in the other portion of the spaces defined by the divider wall. Each of the divider wall, fresh water supply holding structure and waste holding structure are extensible whereby selectively substantially the entire internal space of the shell may be occupied by the fresh water supply holding structure and fresh water therein, or substantially the entire internal space of the shell may be occupied by the waste holding structure and waste therein. The tank is arranged to be substantially full at all times with fresh water drawn from the supply being volumetrically compensated by waste delivered to the waste holding structure.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
229 words
A combination fresh water supply and liquid waste holding tank for use in mobile vehicles, comprising: a bottom half shell defined by a bottom wall, an upright end wall at one end of the bottom wall, and opposed side walls extending downwardly from the top of said end wall to the opposite end of the bottom wall; an upper half shell defined by a top wall, a depending end wall at one end of the top wall, and opposed side walls extending upwardly from the bottom of said end wall to the opposite end of the top wall; means for securing said half shells together with the lower edge of the upper half shell side walls juxtaposed to the upper edge of the lower half shell side walls to define a parallelepiped shell; an extensible divider wall sealingly secured between said half shells and being extensible selectively fully upwardly into said upper half shell and fully downwardly into said lower half shell; first flexible holding means for holding fresh water disposed within the shell above said divider wall; second flexible holding means for holding waste disposed within the shell below said divider wall; first port means for passing fresh water through said shell into and from said first flexible holding means; and second port means for passing waste through said shell into and from said second flexible holding means.
Claim 2
Dependent Claim
229 words
A combination fresh water supply and liquid waste holding tank for use in mobile vehicles, comprising: a bottom half shell defined by a bottom wall, an upright end wall at one end of the bottom wall, and opposed side walls extending downwardly from the top of said end wall to the opposite end of the bottom wall; an upper half shell defined by a top wall, a depending end wall at one end of the top wall, and opposed side walls extending upwardly from the bottom of said end wall to the opposite end of the top wall; means for securing said half shells together with the lower edge of the upper half shell side walls juxtaposed to the upper edge of the lower half shell side walls to define a parallelepiped shell; an extensible divider wall sealingly secured between said half shells and being extensible selectively fully upwardly into said upper half shell and fully downwardly into said lower half shell; first flexible holding means for holding fresh water disposed within the shell above said divider wall; second flexible holding means for holding waste disposed within the shell below said divider wall; first port means for passing fresh water through said shell into and from said first flexible holding means; and second port means for passing waste through said shell into and from said second flexible holding means.
Claim 3
Dependent Claim
26 words
The fresh water supply and liquid waste holding tank of claim 1 wherein said divider wall defines a peripheral flange sealingly secured between said half shells.
Claim 4
Dependent Claim
50 words
The fresh water supply and liquid waste holding tank of claim 1 wherein said divider wall defines a peripheral flange sealingly secured between said half shells and said first flexible holding means comprises a bag having a peripheral flange sealingly secured with said divider wall flange between said half shells.
Claim 5
Dependent Claim
52 words
The fresh water supply and liquid waste holding tank of claim 1 wherein said divider wall defines a peripheral flange sealingly secured between said half shells and said first flexible holding means comprises a parallelepiped bag having a diagonal peripheral flange sealingly secured with said divider wall flange between said half shells.
Claim 6
Dependent Claim
33 words
The fresh water supply and liquid waste holding tank of claim 1 wherein said second flexible holding means comprises a pair of flexible sheets having peripheral portions sealingly secured between said half shells.
Claim 7
Dependent Claim
49 words
The fresh water supply and liquid waste holding tank of claim 1 wherein said first port means comprises a single duct for passing fresh water therethrough into said first flexible holding means for storage therein, and delivering the stored fresh water from said first flexible holding means when desired.
Claim 8
Dependent Claim
39 words
The fresh water supply and liquid waste holding tank of claim 1 wherein said second port means comprises a duct opening through said bottom half shell at the top thereof and extending downwardly therein to adjacent said bottom wall.
Claim 9
Dependent Claim
