Abstract
Abstract The presently invented three tier fountainhead comprises several assembly orientations of modified standard Polyvinyl Chloride (PVC) plumbing parts to form three separate pressure chambers, each of which feed a different tier of water spray. Larger sized standard caps are joined to form the low pressure chamber; one or more intermediate sized caps are employed to form an intermediate pressure chamber; and a length of smaller standard sized PVC pipe is used to form the high pressure chamber which passes centrally through the low and intermediate pressure chambers and is modified with appropriate orifices to feed the low and intermediate pressure chambers. The high pressure chamber is capped at the upper end with a standard PVC cap with appropriate outlet orifices to form the upper tier. The low and intermediate pressure chambers include outlet orifices to form the lower and middle tiers respectively.

Claim 1
Independent Claim
335 words
An ornamental fountainhead to produce three tiers of water spray which is constructed of slightly modified, standard Polyvinyl Chloride, PVC, plumbing parts to form different pressure chambers and flow paths to feed each tier, the construction consists of: a low pressure chamber constructed of an upper and a lower large-sized standard PVC cap connected to each other by a cemented matching sized standard PVC pipe, the upper cap having an upper wall with a hole and having output orifices located circumferentially around the outer portion of the upper wall of said upper cap, the lower cap having a central hole; an intermediate pressure chamber constructed of an upper and a lower intermediate-sized standard PVC pipe cap connected to each other by a cemented matching intermediate-sized standard PVC pipe, the intermediate-sized pipe tightly and axially penetrating the hole in the upper cap of the low pressure chamber, said upper and lower intermediate-sized caps abutting the upper and lower surfaces of the upper wall of the low pressure chamber, respectively, and being cemented thereto, forming a secure seal, the upper and lower caps of the intermediate pressure chamber having centrally located holes, the upper intermediate-sized cap having outlet orifices located circumferentially on the outer edge of the top surface; a high pressure chamber being constructed from a small standard sized PVC pipe and capped at the upper end with a matching sized standard PVC cap, and having one or more outlet orifices on its upper surface, wherein the high pressure chamber passes tightly and axially through the hole in the lower cap of the low pressure chamber forming inlet pressure means for the fountainhead and passes tightly and axially through the holes in the upper and lower caps of the intermediate pressure chamber, the high pressure chamber pipe having an approximate number and sizes of orifices located in a manner to connect the low and intermediate pressure chambers to the high pressure chamber thereby creating a controlled source of water for the low and intermediate pressure chambers.

Claim 3
Dependent Claim
335 words
An ornamental fountainhead to produce three tiers of water spray which is constructed of slightly modified, standard Polyvinyl Chloride, PVC, plumbing parts to form different pressure chambers and flow paths to feed each tier, the construction consists of: a low pressure chamber constructed of an upper and a lower large-sized standard PVC cap connected to each other by a cemented, matching sized standard PVC pipe and having a central hole in the lower cap and multiple outlet orifices located circumferentially around the outer edge of the upper surface of the upper cap such that they penetrate the inner volume of the low pressure chamber; an intermediate pressure chamber constructed of an intermediate-sized standard PVC pipe cap having an upper rim centrally cemented to the under side of the upper wall of the low pressure chamber and having a central hole in a lower wall of the intermediate pressure chamber, said low pressure chamber having a set of outlet orifices located circumferentially around the mid-portion of the upper surface of the upper cap in such a manner as to penetrate the inner volume of the intermediate pressure chamber; a high pressure chamber constructed of a small-sized standard sized PVC pipe, the upper end of the high pressure chamber being centrally cemented to the lower surface of the upper wall of the low pressure chamber, the lower end of the high pressure chamber pipe passing tightly and axially through the hole in the lower cap of the low pressure chamber and forming the inlet means for the fountainhead, and passing through the hole in the lower wall of the intermediate pressure chamber, the high pressure chamber pipe having outlet orifices located such that they connect the high pressure chamber with the low and intermediate pressure chambers, thereby providing a controlled inlet means for the low and intermediate pressure chambers, said low pressure chamber having a set of outlet orifices centrally located in the upper surface of the upper cap such that they penetrate the high pressure chamber.
