Abstract
Abstract A compact, thermostatically controlled water supply system comprising a water heater for supplying hot water through an outlet to a junction with an incoming cold water supply line and a delivery pipe, a flow valve located in one of the lines responsive to the temperature of water flowing through the delivery pipe to control the ratio of cold and hot water mixed at the junction, and pedal-actuated valve in the delivery pipe to permit the flow of mixed water to the lavatory.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
203 words
A water supply system for use with lavatories, said system including cold water supply means for furnishing a flow of cold water through a first line, a water heater having an inlet connected to said first line to receive a flow of cold water therethrough and an outlet for supplying heated water to a second water line, means connected to said first and second lines for mixing the heated water with the cold water for flow through a delivery pipe, temperature responsive valve means in one of said lines for controlling the rate of flow therethrough to effect the ratio of mixture of the heated and cold water, temperature sensing means in heat transfer relation with the water in said delivery pipe and being connected to said temperature responsive valve means to maintain the temperature of the water passing through said delivery pipe within predetermined limits, manual valve means in said delivery pipe for controlling the flow of mixed water therethrough and being movable between a normally closed position and an opened position, and pedal means located adjacent the lavatory for selectively acuating said manual valve means toward its opened position to provide a flow of temperature controlled mixed water to the lavatory.
Claim 2
Dependent Claim
203 words
A water supply system for use with lavatories, said system including cold water supply means for furnishing a flow of cold water through a first line, a water heater having an inlet connected to said first line to receive a flow of cold water therethrough and an outlet for supplying heated water to a second water line, means connected to said first and second lines for mixing the heated water with the cold water for flow through a delivery pipe, temperature responsive valve means in one of said lines for controlling the rate of flow therethrough to effect the ratio of mixture of the heated and cold water, temperature sensing means in heat transfer relation with the water in said delivery pipe and being connected to said temperature responsive valve means to maintain the temperature of the water passing through said delivery pipe within predetermined limits, manual valve means in said delivery pipe for controlling the flow of mixed water therethrough and being movable between a normally closed position and an opened position, and pedal means located adjacent the lavatory for selectively acuating said manual valve means toward its opened position to provide a flow of temperature controlled mixed water to the lavatory.
Claim 3
Dependent Claim
32 words
The structure set forth in claim 1 wherein said system includes a housing adapted to fit beneath the lavatory and including means for supporting said pedal means to permit operative manipulation thereof.
Claim 4
Dependent Claim
19 words
The structure set forth in claim 2 wherein said housing at least partially surrounds said heater and said valves.
Claim 5
Dependent Claim
46 words
The structure set forth in claim 1 wherein said temperature sensing means includes a temperature responsive pressure generating means and said temperature responsive valve means includes pressure responsive means operatively connected to said pressure generating means for controlling the flow of water through the association line.
Claim 6
Dependent Claim
30 words
The structure set forth in claim 4 wherein said means for mixing the heated and cold water includes T connection between said first and second lines and said delivery pipe.
