Abstract
Abstract An evaporative cooler of the invention includes a water distribution system having a dispersion cover spaced from a water pipe having evenly spaced orifices therein for expelling water. The water impinges on a flock-coated concave surface of the dispersion cover. The flock coating retards the water flow and spreads the water flowing downwardly so that the water substantially evenly covers a drip rail at the lower edge of the flock-coated surface adjacent the evaporative medium in the cooler.

Claim 11
Dependent Claim
59 words
A dispersion cover for a fluid distribution system in an evaporative cooler, said dispersion cooler comprising an elongated concave undersurface and an elongated drip rail extending along a lower edge thereof, said undersurface comprising flock-coated surface means for dispersing water impinging thereon, whereby said water spreads over said undersurface and contacts said elongated drip rail substantially along its length.
Claim 12
Dependent Claim
59 words
A dispersion cover for a fluid distribution system in an evaporative cooler, said dispersion cooler comprising an elongated concave undersurface and an elongated drip rail extending along a lower edge thereof, said undersurface comprising flock-coated surface means for dispersing water impinging thereon, whereby said water spreads over said undersurface and contacts said elongated drip rail substantially along its length.
Claim 13
Dependent Claim
55 words
An evaporative cooler comprising a water distribution system which comprises a dispersion cover including fiber-coated concave surface means for spreading water impinging thereon, and an elongated drip rail extending along a lower edge thereof, whereby said water spreads over said surface means and flows downwardly to contact said drip rail substantially along the length thereof.
Claim 14
Dependent Claim
55 words
An evaporative cooler comprising a water distribution system which comprises a dispersion cover including fiber-coated concave surface means for spreading water impinging thereon, and an elongated drip rail extending along a lower edge thereof, whereby said water spreads over said surface means and flows downwardly to contact said drip rail substantially along the length thereof.
Claim 15
Dependent Claim
34 words

Claim 17
Dependent Claim
34 words
An evaporative cooler of claim 11 further comprising a water pipe having orifices substantially evenly spaced therein, secured to said dispersion cover wherein the water impinging on the surface means flows from said orifices.
Claim 18
Dependent Claim
27 words
An evaporative cooler of claim 14 wherein the orifices have a diameter of about 0.12 to 0.16 inches and are spaced about 2.5 to 3.5 inches apart.
