Abstract
Abstract A hydromassage assembly adapted to be permanently embedded in the sidewall of a pool of water and including a detachable aspirator nozzle of nonmetallic material accessible for assembly and disassembly through the discharge port of the embedded assembly. The assembly is highly resistant to erosion from the action of rapidly flowing water and incapable of reacting to form metallic oxides and the like discoloring agents commonly deposited from the water onto the walls of pools and associated equipment.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
186 words
A hydromessage assembly for delivering a highly energized stream of water and air into a body of water below the surface thereof, said assembly comprising a T-shaped molded main body having an open-ended T-head and an open ended T-stem opening into the midportion of said T-head, a nonmetallic aspirator nozzle having a rearwardly flaring water inlet passage opening into a relatively small diameter coaxial discharge passage, means detachably supporting said aspirator nozzle coaxially of said Thead with the discharge end thereof positioned to discharge past the inner end of said T-stem, the outer end of said T-stem being connectable to a supply of air at atmospheric pressure and the end of said T-head adjacent the flaring inlet end of said aspirator nozzle being connectable to a supply of pressurized water, the flow of pressurized water through said nozzle being effective to aspirate a flow of atmospheric air into the outlet end of said T-head for turbulent admixture with the stream of water issuing from said nozzle, and said aspirator nozzle being connectable to and removable from said T-head through the water and air discharge end thereof.
Claim 2
Dependent Claim
186 words
A hydromessage assembly for delivering a highly energized stream of water and air into a body of water below the surface thereof, said assembly comprising a T-shaped molded main body having an open-ended T-head and an open ended T-stem opening into the midportion of said T-head, a nonmetallic aspirator nozzle having a rearwardly flaring water inlet passage opening into a relatively small diameter coaxial discharge passage, means detachably supporting said aspirator nozzle coaxially of said Thead with the discharge end thereof positioned to discharge past the inner end of said T-stem, the outer end of said T-stem being connectable to a supply of air at atmospheric pressure and the end of said T-head adjacent the flaring inlet end of said aspirator nozzle being connectable to a supply of pressurized water, the flow of pressurized water through said nozzle being effective to aspirate a flow of atmospheric air into the outlet end of said T-head for turbulent admixture with the stream of water issuing from said nozzle, and said aspirator nozzle being connectable to and removable from said T-head through the water and air discharge end thereof.
Claim 3
Dependent Claim
31 words
A hydromessage assembly as defined in claim 1 characterized in that said aspirator nozzle is formed from thermoplastic material highly resistive to erosion and wear by rapidly flowing water passing therethrough.
Claim 4
Dependent Claim
43 words
A hydromessage assembly as defined in claim 2 characterized in that the exterior of the discharge end of said aspirator nozzle is generally conical with the smaller end thereof merging with the sidewall of the water flow passage extending longitudinally of said nozzle.
Claim 5
Dependent Claim
23 words
A hydromessage assembly as defined in claim 1 characterized in that said T-shaped main body and said aspirator nozzle comprise molded thermoplastic material.
Claim 6
Dependent Claim
40 words
A hydromessage assembly as defined in claim 1 characterized in that said aspirator nozzle and the interior of said T-head having mating threads cooperating to hold said aspirator nozzle detachably assembled between the inlet and outlet ends of said T-head.
Claim 7
Dependent Claim
184 words
In combination with the sidewall of a masonry pool for water employed for the hydrotherapy treatment of patients, a hydromassage assembly embedded in said sidewall of only the discharge end thereof opening into the water pool below the water surface, said assembly having a unitary hollow main body having aligned inlet and outlet openings, means for supplying pressurized water to said inlet, an air aspirator nozzle detachably mounted coaxially of and between said inlet and outlet openings, the discharge end portion of said aspirator nozzle being shaped to seat a tool insertable into said main body from within said water pOol and usable to assemble and disassemble said aspirator nozzle to and from said main body while said main body remains installed in the sidewall of said pool, and means to supply air at atmospheric pressure into said hollow main body in an area embracing the discharge end portion of said aspirator nozzle whereby the rapid flow of water through said nozzle aspirates a flow of air about the discharge end thereof for turbulent admixture with the stream of water issuing from said nozzle.
Claim 8
Dependent Claim
184 words
In combination with the sidewall of a masonry pool for water employed for the hydrotherapy treatment of patients, a hydromassage assembly embedded in said sidewall of only the discharge end thereof opening into the water pool below the water surface, said assembly having a unitary hollow main body having aligned inlet and outlet openings, means for supplying pressurized water to said inlet, an air aspirator nozzle detachably mounted coaxially of and between said inlet and outlet openings, the discharge end portion of said aspirator nozzle being shaped to seat a tool insertable into said main body from within said water pOol and usable to assemble and disassemble said aspirator nozzle to and from said main body while said main body remains installed in the sidewall of said pool, and means to supply air at atmospheric pressure into said hollow main body in an area embracing the discharge end portion of said aspirator nozzle whereby the rapid flow of water through said nozzle aspirates a flow of air about the discharge end thereof for turbulent admixture with the stream of water issuing from said nozzle.
Claim 9
Dependent Claim
19 words
The combination defined in claim 6 characterized in that hollow main body and said aspirator nozzle are molded thermoplastic.
