Abstract
Abstract This invention is concerned with an anti-pollution device, and particularly a filter for removing deleterious particles and matter from liquids. The invention herein comprises a system and mechanism whereby liquid is caused to flow into a tank. The tank is so arranged that it has an upper area where the floating particles will rise and flow off into a designated receptacle. The heavy particles are caused to flow into a lower area in the tank and the flow of the liquid is slowed down by passing through helicoid ribs so that the heavy particles will have time to fall into a lower area and then into a chute in the bottom of the tank. Then particles are fed by a worm mechanism into a container whereby when enough of the particles have been deposited, the slurry of the particles will be caused to create a pressure so as to open up a valve. They then exit into a designated receptacle. The liquid itself flows into a chamber within the tank and through filtering means removing substantially all of the deleterious particles therefrom and out into a designated receptacle. The filtering means comprise two separate species. In one embodiment the liquid is slowed down by being fed into helicoid ribs around the inner chamber and is further slowed down by fins attached to the bottom of the chamber and then caused to flow upwardly into the chamber and out through an opening. In another species the liquid flows through diatomaceous earth into filter screen tubes and then passes into an upper chamber and out through an opening.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
190 words

Claim 4
Dependent Claim
98 words
An anti-pollution device as described in claim 2 wherein there are a plurality of key brackets mounted on the side of the inner chamber, a plurality of abutments mounted on the sides of the tank having stops at the bottom thereof, said key brackets protruding so as to make contact with said abutments and preventing the inner chamber from rotating within the said tank as the threaded bushing is turned causing said threaded rod to raise and lower said inner chamber, and said stops limiting the vertical distance in which the inner chamber may be lowered or raised.
