Abstract
A self-contained module installed in the side walls or deck of a pool or spa is connected to the pool or spa plumbing system, and converts the turbulent water supply of the system to a laminar sheet of water which free falls into the pool or spa in a manner pleasing in sight and sound. Narrow, elongated spouts prevalent in the prior art have been reduced to a short, compact, economical and structurally stronger emitter owing to the provision of components including an apertured conduit, or "flute", traversing a relatively large manifold chamber open along an element.

Apparatus for producing a sheet waterfall for a pool or spa, comprising:
- an elongated chamber defined in part by a longitudinal encompassing wall, said wall including a longitudinal opening, means including an apertured conduit extending into the chamber for introducing water into the chamber and establishing a laminar flow of water through the opening, said conduit having a fitting for connection to a water supply and at least one aperture for emitting water into the chamber, and a hollow longitudinally extending square-in-section casing encompassing the longitudinal encompassing wall, said casing having a longitudinal slot in registration with the longitudinal opening in the wall.
In apparatus for producing a sheet-like waterfall:
- an elongated housing of generally rectangular cross-section, a longitudinally elongated opening in one wall of the housing, a longitudinally extending conduit within the housing adapted for connection to a supply of pressurized water and having a plurality of longitudinally spaced apertures for emitting water into the housing for discharge in sheet-like form through the opening in the housing wall.
In apparatus for producing a sheet-like waterfall:
- a substantially cylindrical elongated housing having a longitudinally extending elongated opening therein, a longitudinally extending conduit within the housing adapted for connection to a supply of pressurized water and having a plurality of longitudinally spaced apertures facing away from the opening, and a pair of laterally projecting lips extending along opposite sides of the opening and defining a channel for water discharged through the opening.
In apparatus for producing a sheet-like waterfall:
- an elongated housing having a rectangular cross section and a longitudinally extending elongated opening therein, a longitudinally extending conduit within the housing adapted for connection to a supply of pressurized water and having a plurality of longitudinally spaced apertures facing away from the opening, and a pair of laterally projecting lips extending along opposite sides of the opening and defining a channel for water discharged through the opening.
Apparatus for producing sheet waterfall for pool or spa, said apparatus comprising:
- a. an elongated chamber extending along an axis and defined in part by a longitudinal encompassing wall, said wall including a longitudinal opening;
- b. means for introducing water into said chamber;
- and,
- c. means for establishing laminar flow through said opening of water introduced into said chamber, said means including an apertured conduit extending into said chamber parallel to said axis,
- said conduit including a fitting adapted to be connected to a water supply and a plurality of apertures spaced apart longitudinally in said conduit for the emission of water into said chamber, each of said apertures comprising a slot which is substantially a quadrant in angular extent and is transverse to said axis,
- the size of said chamber being large relative to the size of said plurality of apertures so that the velocity of the water emitted from said plurality of apertures into said chamber is substantially reduced.
Apparatus for producing sheet waterfall for pool or spa, said apparatus comprising:
- a. an elongated chamber extending along an axis and defined in part by a longitudinal encompassing wall, said wall including a longitudinal opening defined by an upper edge and a lower edge;
- b. a conduit extending into said chamber parallel to said axis, said conduit including a plurality of apertures for the emission of water into said chamber and a fitting adapted to be connected to a water supply;
- and,
- c. an emitter including an upper lip projecting from said upper edge and a lower lip projecting from said lower edge, said lips defining a channel for water flowing from said opening, the length of said lower lip being approximately equal to the thickness of a pool or spa tile and the length of said upper lip being greater than the length of said lower lip to provide an overhanging portion,
- the size of said chamber being large relative to the size of said plurality of apertures so that the velocity of the water emitted from said plurality of apertures into said chamber when said chamber is filled with water results in a substantial reduction in the Reynolds number characterizing the stream of water flowing toward said opening.
Apparatus for producing a waterfall at a side of a swimming pool, said apparatus comprising:
- a generally cylindrical reservoir adapted to be connected in the water circulation system of said pool, said reservoir having an elongate slot formed in a side wall thereof;
- at least one water discharge metering rod positioned on the axial centerline of said reservoir;
- nozzle means formed in said rod configured, dimensioned, and arranged for directing water in a direction diametrically opposite said elongate slot;
- and
- means for directing water from said reservoir through said elongate slot to the side of said pool.
