Abstract

Abstract A removable waste fluid holding tank for use with a vehicle. A pair of U-shaped supports straps are suspended below the body of the vehicle with the base portion of the strap farthest inwardly from the side of the vehicle lower than the other strap. The tank is constructed to rest on the straps under the body of the vehicle and has an indentation in its base for receiving a portion of one of the straps to inhibit horizontal removal of the tank from the straps. The tank has inlet and vent connections at one end thereof to which drain and vent conduits may connect the tank to plumbing in the vehicle. Within the tank a conduit connects the inlet opening with the base of the tank. A handle is provided for lifting the tank slightly to release it from the strap, allowing it to be pulled horizontally therefrom after such release.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 113 words
In combination with a vehicle having a body with plumbing therein, a liquid holding tank below said plumbing, conduit means extending from said plumbing to the tank, said conduit means connecting with the top of the tank and extending into the tank to a region adjacent the base of the tank and at said region communicating with the interior of the tank, said conduit means further including an expanse outside said tank at an elevation below the base of the tank, and means detachably connecting said conduit means to said plumbing, said conduit means on disconnection from said plumbing being adjustable to provide for the draining of fluid under gravity from said tank.
Claim 2
Dependent Claim 113 words
In combination with a vehicle having a body with plumbing therein, a liquid holding tank below said plumbing, conduit means extending from said plumbing to the tank, said conduit means connecting with the top of the tank and extending into the tank to a region adjacent the base of the tank and at said region communicating with the interior of the tank, said conduit means further including an expanse outside said tank at an elevation below the base of the tank, and means detachably connecting said conduit means to said plumbing, said conduit means on disconnection from said plumbing being adjustable to provide for the draining of fluid under gravity from said tank.
Claim 3
Dependent Claim 173 words
In combination with a vehicle having a frame and a body with plumbing therein mounted on said frame with the underside of the body spaced above the ground, a liquid holding tank, support means secured to said vehicle releasably supporting said holding tank beneath said body with an extremity of the tank adjacent a side of said body, said support means supporting said tank with the base of the tank inclined downwardly progressing inwardly from said side of said body, releasable indent-detent means presented between said support means and the tank operable to lock the tank from displacement laterally of said body, said releasable indent-detent means having a construction whereby with lifting of the tank to raise it from said support means the tank is free to be displaced laterally of said body, drain conduit means connecting said plumbing in said body and said tank with the latter in receiving relationship to fluid flowing from said plumbing through said drain conduit means, and vent conduit means connecting with said tank extending upwardly therefrom.
Claim 4
Dependent Claim 173 words
In combination with a vehicle having a frame and a body with plumbing therein mounted on said frame with the underside of the body spaced above the ground, a liquid holding tank, support means secured to said vehicle releasably supporting said holding tank beneath said body with an extremity of the tank adjacent a side of said body, said support means supporting said tank with the base of the tank inclined downwardly progressing inwardly from said side of said body, releasable indent-detent means presented between said support means and the tank operable to lock the tank from displacement laterally of said body, said releasable indent-detent means having a construction whereby with lifting of the tank to raise it from said support means the tank is free to be displaced laterally of said body, drain conduit means connecting said plumbing in said body and said tank with the latter in receiving relationship to fluid flowing from said plumbing through said drain conduit means, and vent conduit means connecting with said tank extending upwardly therefrom.
Claim 5
Dependent Claim 63 words
The combination of claim 2, wherein said drain conduit means communicates with the interior of said tank adjacent the base of said tank, and said drain conduit means is detachably connected to said plumbing and is flexible, whereby when the drain conduit means is disconnected from the plumbing it is adjustable to provide for the draining of fluid under gravity from said tank.
Claim 6
Dependent Claim 102 words
The combination of claim 2, wherein said drain means is connected to the plumbing by detachable means and is flexible, the drain conduit means connects with the top of the tank and thence extends into the tank to a region adjacent the base of the tank where such is in communication with the interior of the tank, and the drain conduit means further includes an expanse outside the tank at an elevation below the base of the tank, said drain conduit means on being disconnected from said plumbing being adjustable to provide for the draining of fluid under gravity from said tank.
