Abstract
Abstract In apparatus for filtering out objectionable solids and harmful gasses from the exhaust gasses of a combustion engine, a first compartment or chamber containing liquid and through which the exhaust gas passes upwardly so to remove solids such as ash, carbon, soot and the like, a second chamber where neutralizers are introduced to neutralize poisonous gasses passing downwardly, and a third chamber wherein ozone gas can be added and magnetism is incorporated for filtering out metal particles as gasses pass downwardly.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
31 words
In apparatus as set forth in claim 1 including exhaust means coupled to the outlet of said third compartment to move the exhaust gasses through said first, second and third compartments.
Claim 2
Dependent Claim
24 words
In apparatus as set forth in claim 1 wherein said first, second, and third compartments are defined by a common tank with intermediate walls.
Claim 3
Dependent Claim
29 words
In apparatus as set forth in claim 1 wherein said first compartment has means supporting chemicals for releasing solids from the exhaust gasses as they are passed upwardly therethrough.
Claim 4
Dependent Claim
31 words
In apparatus as set forth in claim 1, wherein said third compartment has magnetic means for magnetically removing solids having metallic properties from the gasses passing upwardly through said third compartment.
Claim 5
Dependent Claim
33 words
In apparatus as set forth in claim 1 wherein said first and third compartments are each provided with a sediment collection for the removal of solids collected from the exhaust gasses passing therethrough.
Claim 6
Dependent Claim
275 words
In apparatus for filtering out objectionable solids including ash, carbon, soot and other particles and harmful gasses including posionous gasses from exhaust gasses developed by a combustion engine and the like, the combination comprising: a tank having walls arranged to define first, second and third compartments to successively treat the exhaust gasses, said first compartment having an inlet at the lower end coupled to a duct adapted to receive the exhaust gasses and an outlet at an upper portion communicating with an inlet in an upper portion of second compartment directing the exhaust gasses in an upward direction through the first compartment, said duct being forked with a plurality of channels opening into the first compartment said first compartment containing a liquid having a predetermined level for collecting the solids including ash and carbon soot with the surface of the liquid being above said channels and having a rack supporting chemicals above said channels for releasing said solids from the exhaust gasses as they are passed upwardly therethrough, said second compartment having an outlet in a lower portion communicating with an inlet in a lower portion of said third compartment directing the exhaust gasses downwardly through a third compartment, said second compartment having means for introducing a chemical into the gasses passing downwardly therethrough for contact with the gasses, said third compartment having means for spraying an ozone gas into the gasses passing upwardly through said third compartment, and magnetic means for magnetically removing solids having magnetic properties from the gasses, and exhaust for means coupled to the outlet of said third compartment to move the exhaust gasses through said first, second and third compartments.
