Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
180 words
In an incinerator toilet having a combustion chamber, comminutor plate means for reducing solid waste matter to particle size, means within said combustion chamber for incinerating said solid waste, fan means within said combustion chamber for drawing air into said chamber for supporting combustion and for cooling said chamber after incineration of the solid waste matter is completed, and discharge pipe means for exhausting air from said combustion chamber to atmosphere, the improvement comprising a liquid storage chamber located in a position to receive liquid from said combustion chamber, pump means connected to said liquid storage chamber and adapted to receive liquid therefrom, a discharge line having one end connected to said pump for receiving liquid under pressure therefrom, nozzle means connected to the opposite end of said discharge pipe, said nozzle means having a discharge portion located within said combustion chamber, whereby liquid waste matter is selectively projected into the combustion chamber when said chamber is at an elevated temperature so that liquid waste matter is vaporized and the vapor is discharged to atmosphere through said discharge pipe means.
Claim 2
Dependent Claim
180 words
In an incinerator toilet having a combustion chamber, comminutor plate means for reducing solid waste matter to particle size, means within said combustion chamber for incinerating said solid waste, fan means within said combustion chamber for drawing air into said chamber for supporting combustion and for cooling said chamber after incineration of the solid waste matter is completed, and discharge pipe means for exhausting air from said combustion chamber to atmosphere, the improvement comprising a liquid storage chamber located in a position to receive liquid from said combustion chamber, pump means connected to said liquid storage chamber and adapted to receive liquid therefrom, a discharge line having one end connected to said pump for receiving liquid under pressure therefrom, nozzle means connected to the opposite end of said discharge pipe, said nozzle means having a discharge portion located within said combustion chamber, whereby liquid waste matter is selectively projected into the combustion chamber when said chamber is at an elevated temperature so that liquid waste matter is vaporized and the vapor is discharged to atmosphere through said discharge pipe means.
Claim 3
Dependent Claim
70 words
The structure of claim 1 including shaft means extending through said liquid storage chamber, said comminutor plate means and said fan means being mounted on said shaft means, bearing means supporting said shaft means, means for rotating said shaft means, a well mounted within said liquid storage chamber and disposed about said bearing means, said well adapted to receive liquid from said combustion chamber to keep said bearing means cool.
Claim 4
Dependent Claim
55 words
The structure of claim 1 including a baffle box located intermediate the ends of said discharge pipe, said baffle box having a plurality of baffles for causing air from said chamber to move in a serpentine path so that particles of ash fall out of suspension, and drawer means in said box for collecting ash.
Claim 5
Dependent Claim
22 words
The structure of claim 1 in which said nozzle means is an atomizing nozzle for reducing said liquid to a fine mist.
Claim 6
Dependent Claim
166 words
Apparatus for treating liquid waste matter comprising a combustion chamber, means within said chamber for comminuting solid waste matter, means for introducing a combustible mixture into said chamber at high velocity, means for igniting said combustible mixture, means for directing the ignited mixture in a swirling, burning path around the inner surface of said combustion chamber, A liquid storage chamber in communication with said combustion chamber and adapted to receive liquid waste matter therefrom, pump means for removing liquid waste matter from said liquid storage chamber, discharge pipe means connected at one end to said pump means and connected at the opposite end to a nozzle, a portion of said nozzle being located within said combustion chamber, whereby fluid from said fluid storage chamber is sprayed under pressure into the combustion chamber after incineration of solid waste matter has been completed to accelerate the cooling of the combustion chamber as well as to vaporize the liquid waste matter after which the vapor is exhausted to atmosphere.
Claim 7
Dependent Claim
166 words
Apparatus for treating liquid waste matter comprising a combustion chamber, means within said chamber for comminuting solid waste matter, means for introducing a combustible mixture into said chamber at high velocity, means for igniting said combustible mixture, means for directing the ignited mixture in a swirling, burning path around the inner surface of said combustion chamber, A liquid storage chamber in communication with said combustion chamber and adapted to receive liquid waste matter therefrom, pump means for removing liquid waste matter from said liquid storage chamber, discharge pipe means connected at one end to said pump means and connected at the opposite end to a nozzle, a portion of said nozzle being located within said combustion chamber, whereby fluid from said fluid storage chamber is sprayed under pressure into the combustion chamber after incineration of solid waste matter has been completed to accelerate the cooling of the combustion chamber as well as to vaporize the liquid waste matter after which the vapor is exhausted to atmosphere.
Claim 8
Dependent Claim
108 words
Apparatus for treating liquid waste matter comprising a combustion chamber, means for comminuting solid waste matter, means for distributing the comminuted waste matter about said chamber, means for incinerating said solid waste matter, a liquid storage chamber adapted to receive liquid waste matter from said combustion chamber, means for removing liquid waste matter from said liquid storage chamber, means whereby fluid from said fluid storage chamber is sprayed under pressure into the combustion chamber after incineration of solid waste matter has been completed to accelerate the cooling of the combustion chamber as well as to vaporize the liquid waste matter after which the vapor is exhausted to atmosphere.
Claim 9
Dependent Claim
108 words
Apparatus for treating liquid waste matter comprising a combustion chamber, means for comminuting solid waste matter, means for distributing the comminuted waste matter about said chamber, means for incinerating said solid waste matter, a liquid storage chamber adapted to receive liquid waste matter from said combustion chamber, means for removing liquid waste matter from said liquid storage chamber, means whereby fluid from said fluid storage chamber is sprayed under pressure into the combustion chamber after incineration of solid waste matter has been completed to accelerate the cooling of the combustion chamber as well as to vaporize the liquid waste matter after which the vapor is exhausted to atmosphere.
