Abstract
Abstract Apparatus for producing a waterfall at the edge of a swimming pool, spa or pond, the apparatus including a generally cylindrical reservoir in the water circulation system path, with at least one water discharge metering rod on the axial centerline of the reservoir, configured for directing water in a first direction diametrically opposite an elongate discharge plenum having a second plenum in fluid flow communication therewith for discharging the water into the pool through a sidewall thereof. The apparatus is placed inside the wall on the side of the pool and produces a smooth even sheet of water which is directed away from the side of the pool. The metering rods are constructed for adjusting pressure along the axial length thereof to cause the water pressure inside of the unit to be maintained evenly across its length thereby directing the water out through the throat of the discharge plenum.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
190 words
Apparatus for producing a waterfall at a side of a swimming pool and being capable of producing a smooth sheet of water which is directed away from the side of the pool, said apparatus comprising: elongate reservoir means adapted to be encapsulated by gunite in the side of said pool for receiving water, said reservoir means including an elongate slotted opening; water flow means having at least one tubular member axially positioned along the axis of and within said reservoir means for flowing water to said reservoir means; means for coupling an external source of water to said water flow means; nozzle means in said tubular member formed on a line generally opposite said slotted opening for providing communication between said tubular member and said reservoir means; valve means at least partially formed within said tubular member for enabling equalization of water pressure along the length of said tubular member with water provided to said coupling means to provide a generally uniform water pressure along the length of said slotted opening; and means for directing water from said reservoir means through said slotted opening to the side of said pool.
Claim 2
Dependent Claim
190 words
