Abstract
Abstract An apparatus for treating water or other liquid comprises outwardly extending front side walls defining an entrance for water to be treated, intermediate inwardly extending side walls, central parallel side walls and outwardly extending rear walls defining an exit for treated water or other liquid. A stepped bottom is integral with and between the side walls. A housing, slidable on the top edges of the side walls, is provided for holding a chemical solution to be dispensed into the water to be treated. A float housing integral with one of the intermediate side walls contains a float which is raised or lowered according to the volume of water flowing between the side walls. A valve on the housing is interconnected with the float whereby the solution within the housing is dispensed into the water or liquid to be treated in proportion to the volume of water flowing between the side walls. A chemical solution is fed from a bulk storage container to the housing through a float valve which insures that the housing will always contain an adequate supply of chemicals.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
143 words
A water treating apparatus comprising: front side walls; intermediate side walls; central side walls; rear side walls; a bottom wall between said side walls; a float housing on one of said intermediate side walls; a float supported on a vertically movable rod within said float housing; a chemical solution holding housing on top of said walls; a valve exterior of said chemical solution holding housing and communicating with the interior thereof; means supported on support means and interconnected with said float and said valve operable in response to upward or downward movement of said float to open or close said valve in response to water or liquid flow through said apparatus; a valve within said chemical solution holding housing; and a bulk storage container connected to said valve within said chemical solution holding housing whereby said container is replenished with a chemical solution.
Claim 2
Dependent Claim
143 words
A water treating apparatus comprising: front side walls; intermediate side walls; central side walls; rear side walls; a bottom wall between said side walls; a float housing on one of said intermediate side walls; a float supported on a vertically movable rod within said float housing; a chemical solution holding housing on top of said walls; a valve exterior of said chemical solution holding housing and communicating with the interior thereof; means supported on support means and interconnected with said float and said valve operable in response to upward or downward movement of said float to open or close said valve in response to water or liquid flow through said apparatus; a valve within said chemical solution holding housing; and a bulk storage container connected to said valve within said chemical solution holding housing whereby said container is replenished with a chemical solution.
Claim 3
Dependent Claim
58 words
A water treating apparatus as defined in claim 1, wherein: said bottom wall is stepped from a higher elevation to a lower elevation and said walls therebetween are parallel thus defining a venturi whereby water or liquid having treating chemicals therein is accelerated causing turbulence which results in thorough mixing of the chemical solution and water or liquid.
Claim 4
Dependent Claim
27 words
A water treating apparatus as defined in claim 1, wherein: said side walls are integral and said float housing integral with one of said intermediate side walls.
Claim 5
Dependent Claim
37 words
A water treating apparatus as defined in claim 1, wherein: said solution holding housing has means for permitting adjustment of said interconnecting means for the purpose of calibrating said valve exterior of said chemical solution holding housing.
Claim 6
Dependent Claim
46 words
A water treating apparatus as defined in claim 1, wherein: said support means comprises, a flange extending inwardly of one of said intermediate side walls adjacent the upper edge thereof and a vertical panel having a slot in the upper edge thereof supported on said flange.
Claim 7
Dependent Claim
36 words
A water treating apparatus as defined in claim 1, wherein: said means interconnecting said float and said valve comprises a bar selectively pivotably supported on said support means and selectively pivotably attached to a valve operator.
Claim 8
Dependent Claim
75 words
A water treating apparatus as defined in claim 6, wherein: said bar is attached to said float at one end and attached to a valve operator at the opposite end whereby when said float is raised or lowered in response to water flow through said apparatus, said valve operator is raised or lowered accordingly to progressively open or close said valve thus controlling the dispensing of a chemical treating solution into the water or liquid.
Claim 9
Dependent Claim
44 words
A water treating apparatus as defined in claim 1, wherein: said chemical solution is dispensed into the water or liquid in the elevated portion of the bottom wall by a flexible tube extending from said valve to a position near said elevated bottom wall.
Claim 10
Dependent Claim
29 words
A water treating apparatus as defined in claim 1, wherein: said solution housing is replenished with a chemical solution through a valve therein connected to a bulk storage container.
Claim 11
Dependent Claim
70 words
A water treating apparatus as defined in claim 1, wherein: said front walls extend outwardly defining a wide entrance for water or liquid, said intermediate side walls extend inwardly from said front walls, said center side walls extend from said intermediate side walls and parallel for a distance, and said rear walls extend outwardly from said center parallel side walls and define a wide exit for treated water or liquid.
Claim 12
Dependent Claim
33 words
A water treating apparatus as defined in claim 1, wherein: said valve exterior of said housing is calibrated by selectively adjusting the pivot points connecting the valve operator and the float support rod.
Claim 13
Dependent Claim
26 words
A water treating apparatus as defined in claim 1, and: means between said intermediate side walls for measuring the volume of water flowing through said apparatus.
