Abstract
Abstract A fireproof, hyperbolic, natural draft, crossflow water cooling tower having two story fill assembly structure between respective concrete hot water distribution and cold water basins within the tower shell and integral therewith adjacent the air inlet of the shell. Stainless steel fill and eliminator supports suspended from the distribution and basin units carry transversely threequarter wave asbestos cement board fill members and transversely full wave eliminator bars respectively cut from corrugated sheets. The fill members are disposed on edge with the longitudinal length thereof parallel to the air flow through each fill assembly structure while the eliminator bars lie in flat, generally horizontal disposition with the longitudinal axes thereof slightly tilted for drainage of the bars and located perpendicular to the path of travel of air through respective fill assembly structures.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
177 words
A cooling tower comprising: an upright, natural draft shell provided with an open top defining an air discharge outlet and an air inlet around the perimeter of the shell at the bottom thereof; upper and lower, vertically spaced cold water basins underlying at least the interior portion of the shell proximal to said air inlet thereof; upper and lower annular hot water distribution means within the shell above the upper and lower cold water basins respectively; and fill assembly structure within the shell between each hot water distribution means and the cold water basin therebelow in positions for movement of air therethrough from the air inlet toward the discharge outlet in crossflowing relationship to hot water gravitating through corresponding fill assembly structures from the hot water distribution thereabove toward the underlying cold water basin, a part of said shell being configured to define the outer, upright, annular wall portion of each of said hot water distribution means, the lower hot water distribution means being located at essentially the same horizontal level as the upper cold water basin.
Claim 2
Dependent Claim
177 words
A cooling tower comprising: an upright, natural draft shell provided with an open top defining an air discharge outlet and an air inlet around the perimeter of the shell at the bottom thereof; upper and lower, vertically spaced cold water basins underlying at least the interior portion of the shell proximal to said air inlet thereof; upper and lower annular hot water distribution means within the shell above the upper and lower cold water basins respectively; and fill assembly structure within the shell between each hot water distribution means and the cold water basin therebelow in positions for movement of air therethrough from the air inlet toward the discharge outlet in crossflowing relationship to hot water gravitating through corresponding fill assembly structures from the hot water distribution thereabove toward the underlying cold water basin, a part of said shell being configured to define the outer, upright, annular wall portion of each of said hot water distribution means, the lower hot water distribution means being located at essentially the same horizontal level as the upper cold water basin.
Claim 3
Dependent Claim
36 words
A cooling tower as set forth in claim 1, wherein is provided a common annular floor defining the bottom of said lower hot water distribution means and the bottom of the upper cold water basin respectively.
Claim 4
Dependent Claim
40 words
A cooling tower as set forth in claim 2, wherein is provided an upright divider wall on said floor intermediate the opposed annular margins thereof, and an inner upright wall on the floor in spaced relationship from said divider wall.
Claim 5
Dependent Claim
52 words
A cooling tower as set forth in claim 1, wherein said upper hot water distribution means and the upper cold water basin therebelow are offset inwardly of the shell toward the vertical axis thereof with respect to the lower hot water distribution means and the lower cold water basin below the same.
Claim 6
Dependent Claim
28 words
A cooling tower as set forth in claim 1, wherein at least said hot water distribution means and the upper cold water basin are integral with the shell.
Claim 7
Dependent Claim
25 words
A cooling tower as set forth in claim 1, wherein said shell, the hot water distribution means and said cold water basins are of concrete.
