Claim 5

The invention as defined in claim 3 wherein said flow directing means includes baffle means projecting upwards towards said covering shroud for balancing the flow of water to offset the kinetic energy of initial water velocity.

Claim 6

The invention as defined in claim 4 wherein said covering shroud and said distribution pan are molded from a plastic material.

Claim 7

In a cooling tower including a hot water basin for receipt of water to be cooled having spray nozzles pOsitioned in the floor thereof, a manifold pipe positioned above said hot water basin having openings therein with control valve means associated therewith, and a distribution box associated with said control valve means for receiving water to be cooled from said manifold pipe and uniformly distributing it over said hot water basin floor; said distribution box comprising: a. a covering shroud having an opening in fluid communication with and secured immediately below said control valve means for receiving water from said manifold pipe; and b. a distribution pan positioned immediately below and covered by said covering shroud having a plurality of flow directing means formed integral therewith for receiving the water directed thereon from said covering shroud and uniformly distributing it in a substantially horizontal direction over said water basin floor.

Claim 8

In a cooling tower including a hot water basin for receipt of water to be cooled having spray nozzles pOsitioned in the floor thereof, a manifold pipe positioned above said hot water basin having openings therein with control valve means associated therewith, and a distribution box associated with said control valve means for receiving water to be cooled from said manifold pipe and uniformly distributing it over said hot water basin floor; said distribution box comprising: a. a covering shroud having an opening in fluid communication with and secured immediately below said control valve means for receiving water from said manifold pipe; and b. a distribution pan positioned immediately below and covered by said covering shroud having a plurality of flow directing means formed integral therewith for receiving the water directed thereon from said covering shroud and uniformly distributing it in a substantially horizontal direction over said water basin floor.

Claim 9

The invention as defined in claim 6 wherein said control valve means includes a body portion extending downward from said manifold pipe and the opening in said covering shroud is positioned around said body portion.

Claim 10

The invention as defined in claim 7 wherein said covering shroud is of two piece construction secured together around said body portion with sealing material positioned therebetween.

Claim 11

The invention as defined in claim 8 wherein said covering shroud has a conical diverging section molded integral therewith to direct the discharge of water from said control valve means upon said distribution pan.

Claim 12

The invention as defined in claim 6 wherein said covering shroud is secured to and spaced from said distribution pan by a plurality of bolt means received by spacers positioned therebetween so as to permit an operator to stand on said cover shroud for inspection and adjustment of said control valve means.

Claim 13

The invention as defined in claim 10 wherein said bolt means are received by well-nuts positioned in said hot water basin floor.

Claim 14

The invention as defined in claim 11 wherein said distribution pan includes a plurality of cut-outs in vertical alignment with said nozzles in said hot water basin floor therebelow so as to permit the passage of water therethrough.

Claim 15

The invention as defined in claim 6 wherein said flow directing means includes a cone means, and a plurality of rib means and baffle means projecting upward towards said covering shroud for effecting a uniform distribution of water over said distribution pan.

Claim 16

In a cooling tower including a hot water basin for receipt of water to be cooled having spray nozzles positioned in the floor thereof, a manifold pipe positioned above said hot water basin having openings therein with control valve means associated therewith, and a distribution box associated with said control valve means for receiving water to be cooled from said manifold pipe and uniformly distributing it over said hot water basin floor; said distribution box comprising: a. a plastic covering shroud having an opening in fluid communication with and secured immediately below said control valve means for receiving water from said manifold pipe, said covering shroud being integrally formed with a conically diverging section; and b. a plastic distribution pan positioned immediately below and covered by said covering shroud having a plurality of flow directing means formed integral therewith for receiving the water directed thereon from said covering shroud and uniformly distributing it in a substantially horizontal direction over said water basin floor; c. said flow directing means includes a cone means, and a plurality of rib means and baffle means projecting upward towards said covering shroud for effecting a uniform distribution of water over said distribution pan.

Claim 17

In a cooling tower including a hot water basin for receipt of water to be cooled having spray nozzles positioned in the floor thereof, a manifold pipe positioned above said hot water basin having openings therein with control valve means associated therewith, and a distribution box associated with said control valve means for receiving water to be cooled from said manifold pipe and uniformly distributing it over said hot water basin floor; said distribution box comprising: a. a plastic covering shroud having an opening in fluid communication with and secured immediately below said control valve means for receiving water from said manifold pipe, said covering shroud being integrally formed with a conically diverging section; and b. a plastic distribution pan positioned immediately below and covered by said covering shroud having a plurality of flow directing means formed integral therewith for receiving the water directed thereon from said covering shroud and uniformly distributing it in a substantially horizontal direction over said water basin floor; c. said flow directing means includes a cone means, and a plurality of rib means and baffle means projecting upward towards said covering shroud for effecting a uniform distribution of water over said distribution pan.

Claim 18

The invention as defined in claim 14 wherein said covering shroud is secured to and spaced from said pan by a plurality of bolt means received by spacers positioned therebetween so as to permit an operator to stand on said cover shroud for inspection and adjustment of said control valve means.
