Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
157 words
A hydromassage bath assembly for installation in a system having a drain line, comprising: a bath tank having vertical walls and a bottom wall, one of said walls having an overflow opening, and said bottom wall having a drain opening, and means for connecting said overflow opening to said drain line; a jet assembly mounted in a vertical wall of said tank at a location spaced from said drain opening, and including a jet nozzle; a pump having an intake end and a discharge end; means flow connecting said pump discharge end along the outside of said tank to said jet nozzle; and means for selectively flow connecting said drain opening to said pump intake end and to said drain line, each to the exclusion of the other, whereby said pump may circulate the water in said system to the exclusion of said drain line, or drain to said drain line along with water from said tank.
Claim 2
Dependent Claim
157 words
A hydromassage bath assembly for installation in a system having a drain line, comprising: a bath tank having vertical walls and a bottom wall, one of said walls having an overflow opening, and said bottom wall having a drain opening, and means for connecting said overflow opening to said drain line; a jet assembly mounted in a vertical wall of said tank at a location spaced from said drain opening, and including a jet nozzle; a pump having an intake end and a discharge end; means flow connecting said pump discharge end along the outside of said tank to said jet nozzle; and means for selectively flow connecting said drain opening to said pump intake end and to said drain line, each to the exclusion of the other, whereby said pump may circulate the water in said system to the exclusion of said drain line, or drain to said drain line along with water from said tank.
Claim 3
Dependent Claim
117 words
A hydromassage bath assembly in accordance with claim 1, characterized by said selective flow connecting means including a hollow fitting flow coupled to said drAin opening, conduit means flow connected to said fitting for flow connecting said fitting to said drain line, and a drain valve in the flow passageway formed between said fitting and said conduit means, and means in a wall of said fitting above the location of said drain valve, for flow connecting said drain opening to the intake end of said pump when said valve is closed, and to permit said pump to drain to said drain line when said valve is open to flow connect said drain opening to said drain line.
Claim 4
Dependent Claim
63 words
A hydromassage bath assembly in accordance with claim 1, characterized by a first jet assembly mounted at substantially the junction of a side and end wall, and a second jet assembly mounted substantially diagonally therefrom, with the nozzle of each jet assembly connected to the pump discharge end, and said tank having its cavity contoured to encourage placing oneself along the other diagonal.
Claim 5
Dependent Claim
28 words
A hydromassage bath assembly in accordance with claim 2, characterized by all flow passageways between said pump and said jet assembly being above said drain valve in elevation.
Claim 6
Dependent Claim
37 words
A hydromassage bath assembly in accordance with claim 1, characterized by said means for flowing connecting the pump discharge end to said nozzle including a pipe connection sloping upwardly from said pump discharge end to said nozzle.
Claim 7
Dependent Claim
141 words
A hydromassage bath installation comprising: a bath tank having vertical walls and a bottom wall, one of said vertical walls having an overflow opening, and said bottom wall having a drain opening; a jet assembly mounted in a vertical wall of said tank at a location spaced from said drain opening, and including a jet nozzle; a pump having an intake end and a discharge end; means flow connecting said pump discharge end along the outside of said tank to said jet nozzle; a drain line; and means for selectively flow connecting said drain opening to said pump intake end and to said drain line, each to the exclusion of the other, whereby said pump may circulate the water in said system to the exclusion of said drain line, or drain to said drain line along with water from said tank.
Claim 8
Dependent Claim
141 words
A hydromassage bath installation comprising: a bath tank having vertical walls and a bottom wall, one of said vertical walls having an overflow opening, and said bottom wall having a drain opening; a jet assembly mounted in a vertical wall of said tank at a location spaced from said drain opening, and including a jet nozzle; a pump having an intake end and a discharge end; means flow connecting said pump discharge end along the outside of said tank to said jet nozzle; a drain line; and means for selectively flow connecting said drain opening to said pump intake end and to said drain line, each to the exclusion of the other, whereby said pump may circulate the water in said system to the exclusion of said drain line, or drain to said drain line along with water from said tank.
Claim 9
Dependent Claim
73 words
A hydromassage bath installation in accordance with claim 6, characterized by said selective flow connecting means including a hollow fitting flow coupled to said drain opening, conduit means flow connecting said drain line to said fitting and a drain valve in the flow passageway formed between said fitting and conduit means, and means flow connecting said pump intake end to said fitting in a wall thereof at a location above said drain valve.
