Abstract
A waterfall fixture for expelling water in sheet form comprises a housing having a cavity divided into chambers by apertured plates extending across the cavity. The plates are apertured and spaced from each other and from the inlet and outlet of the fixture to define multiple chambers within the cavity separated from one another by the plates. A first plate is opposed to the inlet and acts as a screen to block debris and as a barrier to incoming water to distribute the water into a laminar flow through the chamber defined between the first plate and the inlet. A second plate is opposed to the first screen and helps to further distribute the water into laminar flow and may be valved to assure a perfect laminar sheet style water flow pattern.
Claims28
A waterfall fixture for expelling water in sheet form, said fixture comprising:
- (a) a housing defining an elongate closed cavity having an inlet opening in one side for receiving water under pressure and an outlet opening spaced from the inlet opening for expelling water in sheet form, said outlet opening being elongate and extending longitudinally of the housing;
- (b) a plurality of apertured divider plates extending longitudinally through the cavity between the inlet and outlet openings in spaced apposition to one another to define one or more chambers therebetween and a chamber to either side thereof in apposition to the inlet and outlet openings, said chambers being disposed in aligned succession between the inlet and outlet openings and said plates each defining a plurality of apertures.
A waterfall fixture comprising:
- a) a housing having an inlet opening for receiving water under pressure and outlet opening for expelling water in sheet form, said outlet opening being of a generally slot shaped horizontal configuration with spaced upper and lower edges;
- b) an elongate cavity formed within the housing through which water can pass from the inlet opening to the outlet opening, said outlet opening extending longitudinally of and opening through one side of the cavity;
- c) a first divider plate extending longitudinally through and across the cavity to define a chamber between said first plate and the inlet opening, said first divider plate having a plurality of spaced apertures extending therethrough;
- d) a second divider plate extending longitudinally through the cavity to define a chamber between the second plate and the outlet opening, said second divider plate being spaced from the first divider plate and having a plurality of spaced apertures extending therethrough;
- e) a third divider plate extending longitudinally through the cavity between the first and second plates to define chambers between said third plate and each of said first and second plates, said third divider plate having a plurality of spaced apertures extending therethrough and wherein;
- f) the respective chambers are disposed in aligned succession between the inlet and outlet openings.
A waterfall fixture for expelling water in sheet form, said fixture comprising:
- a) a housing defining an elongate closed cavity having an inlet opening in one side for receiving water under pressure and an outlet slot spaced from the inlet opening for expelling water in sheet form, said outlet slot having spaced upper and lower edges, being elongate, and extending longitudinally of the housing;
- b) a plurality of apertured divider screen plates extending longitudinally through the cavity between the inlet opening and outlet slot in spaced apposition to one another to define one or more chambers therebetween and a chamber to either side thereof in apposition to the inlet opening and outlet slot, said plates each defining a plurality of screening apertures;
- and wherein:
- 1) a first of said plates is disposed in opposed spaced relationship to the inlet opening to define the chamber in apposition to the inlet opening;
- and
- 2) the apertures in the first plate have a cross-section no greater than the spacing between the upper and lower edges of the outlet slot.
A waterfall fixture for expelling water in sheet form, said fixture comprising:
- a) a housing defining an elongate closed cavity having an inlet opening in one side for receiving water under pressure and an outlet slot for expelling water in sheet form, said outlet slot having spaced upper and lower edges, being elongate, and extending longitudinally of the housing;
- b) a plurality of apertured divider screen plates extending longitudinally through the cavity between the inlet opening and outlet slot in spaced apposition to one another to define one or more chambers therebetween and a chamber to either side thereof in apposition to the inlet opening and outlet slot, said plates each defining a plurality of screening apertures;
- and wherein:
- the apertures in at least one of the screening plates have a cross-section no greater than the spacing between the upper and lower edges of the outlet slot.
