Abstract
Abstract An supplantary reservoir supplants the original integral reservoir of an evaporative cooler eliminating the necessity for accumulating water in said original integral reservoir. The water circulating pump and float controlled valve of the original, conventional cooler may be transferred physically and functionally to the supplantary reservoir. Communication of water from the conventional cooler to and from the supplantary reservoir is by means of the drain opening in the base of the original integral reservoir. The supplantary reservoir is readily accessible providing easy maintenance thereof and inexpensive replacement if necessary.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
121 words
In an evaporative cooler having means for passing air past and through evaporative cooling pads which pads are maintained saturated with water drawn by water circulating means from a reservoir forming part of the base of said cooler said water being maintained within said reservoir by a float controlled valve coupling a source of water to said reservoir said reservoir being further provided with means for draining water from the base of said reservoir when desired to do so, the improvement comprising: a supplantary water retention vessel external to said evaporative cooler supplanting said reservoir and coupled thereto by said means for draining water from the base of said reservoir to preclude the accumulation and storage of water within said reservoir.
Claim 2
Dependent Claim
121 words
In an evaporative cooler having means for passing air past and through evaporative cooling pads which pads are maintained saturated with water drawn by water circulating means from a reservoir forming part of the base of said cooler said water being maintained within said reservoir by a float controlled valve coupling a source of water to said reservoir said reservoir being further provided with means for draining water from the base of said reservoir when desired to do so, the improvement comprising: a supplantary water retention vessel external to said evaporative cooler supplanting said reservoir and coupled thereto by said means for draining water from the base of said reservoir to preclude the accumulation and storage of water within said reservoir.
Claim 3
Dependent Claim
20 words
The improvement of claim 1 further comprising means for coupling said supplantary water retention vessel to a source of water.
Claim 4
Dependent Claim
25 words
The improvement of claim 2 wherein said means for coupling said supplantary water retention vessel to a source of water comprises a float controlled valve.
Claim 5
Dependent Claim
23 words
The improvement of claim 3 wherein said float controlled valve comprises that float controlled valve originally used to maintain water within said reservoir.
Claim 6
Dependent Claim
34 words
The improvement of claim 4 further comprising water circulating means for drawing water from said supplantary water retention vessel and coupling same to said evaporative cooling pads to maintain said pads saturated with water.
Claim 7
Dependent Claim
27 words
The improvement of claim 5 wherein said water circulating means comprises that water circulating means originally used to draw water from said reservoir to saturate said pads.
Claim 8
Dependent Claim
19 words
The improvement of claim 1 further comprising means for supporting said supplantary water retention vessel external to said cooler.
Claim 9
Dependent Claim
44 words
The improvement of claim 7 wherein said evaporative cooler further comprises means for mounting said cooler above a stable base and said means for supporting said supplantary water retention vessel external to said cooler comprises vessel support means coupled to said cooler mounting means.
Claim 10
Dependent Claim
48 words
The improvement of claim 8 wherein said means for mounting said cooler above a stable base comprises means for mounting said cooler above a sloping roof and said vessel support means comprises a support shelf coupled interior of said means for mounting said cooler above a sloping roof.
Claim 11
Dependent Claim
33 words
The improvement of claim 9 further comprising exterior access means to said vessel when said vessel is supported on said shelf interior of said means for mounting said cooler above a sloping roof.
