Abstract
Abstract A fill assembly for a cooling tower which includes a plurality of parallel, spaced-apart, superimposed support members on which are mounted a plurality of trays. The support members are at an angle but each of the trays are mounted so that they are generally horizontal. The trays are provided with holes therethrough to permit water to gravitate through the fill assembly. Air flows through the fill assembly between the trays to cool the water.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
99 words
In combination with a cooling tower, a fill assembly through which water to be cooled is adopted to gravitate and air is adapted to flow comprising; a plurality of parallel, spaced-apart superimposed support members; means for mounting said support members within said cooling tower so that said support members are at an angle to horizontal; and tray means mounted on each of said support members; said tray means being arranged in steplike pattern and positioned substantially horizontally provided with a plurality of holes therethrough for permitting water which gravitates through the fill assembly to pass through the tray means.
Claim 2
Dependent Claim
