Automatic still

Claim 1

AN AUTOMATIC STILL FOR PRODUCING DISTILLED WATER FROM RAW WATER WHICH COMPRISES A FRAME, A BOILER ON SAID FRAME, AN ELECTRIC HEATER IN THERMAL CONDUCTING RELATIONSHIP WITH SAID BOILER FOR HEATING THE SAME, MEANS COMPRISING AN INLET CONDUIT CONNECTED TO SAID BOILER FOR CONDUCTING RAW WATER TO SAID BOILER FROM A RAW WATER SOURCE, AN ELECTRICALLY ACTUATED VALVE IN SAID INLET, CONDUIT FOR REGULATING THE FLOW OF RAW WATER TO THE BOILER, MEANS COMPRISING AN ELECTRIC SWITCH FOR CONTROLLING THE OPERATION OF SAID VALVE IN THE INLET CONDUIT, SAID ELECTRIC SWITCH COMPRISING A THEMOSTAT WHICH IS OPERABLE RESPONSIVE TO THE LEVEL OF WATER IN SAID BOILER FOR ACTUATING SAID SWITCH WHICH OPERATES SAID VALVE, A VERTICALLY INCLINED TUBE CONDENSER DISPOSED AT THE UPPER END OF SAID FRAME, SAID TUBE CONDENSER COMPRISING A PLURALITY OF RADIATING FINS AND HAVING AN INLET AT ITS UPPER END AND AN OUTLET AT ITS LOWER AND OPPOSITE END, CONDUIT MEANS CONNECTING SAID BOILER TO THE INLET OF SAID CONDENSER FOR CONDUCTING VAPOR FROM THE BOILER INTO THE CONDENSER WHERE SAID VAPOR IS CONDENSED TO DISTILLED WATER AND FLOWS BY GRAVITY DOWNWARDLY OF THE INCLINED CONDENSER TUBE TO THE OUTLET THEREOF, A DISTILLED WATER TANK ON SAID FRAME AND DISPOSED AJACENT THE OUTLET OF SAID CONDENSER FOR RECEIVING AND STORING DISTILLED WATER, MEANS COMPRISING A THERMOSTAT-CONTROLLED ELECTRIC SWITCH WHICH IS ELECTRICALLY CONNECTED TO SAID HEATER, SAID THERMOSTAT-CONTROLLED SWITCH BEING ACTUATED RESPONSIVE TO THE LEVEL OF DISTILLED WATER IN SAID TANK, SAID ELECTRIC HEATER BEING DE-ENERGIZED BY SAID THERMOSTAT-CONTROLLED ELECTRIC SWITCH WHEN THE LEVEL OF DISTILLED WATER IN SAID TANK REACHES A SUFFICIENTLY HIGH LEVEL, SAID THERMOSTAT-CONTROLLED SWITCH BEING ENERGIZED TO ACTUATE SAID HEATER WHEN THE LEVEL OF THE DISTILLED WATER IN SAID TANK FALLS TO A LOW LEVEL, A DISTILLED WATER OUTLET CONDUIT IN COMMUNICATION WITH SAID TANK AND EXTENDING SUBSTANTIALLY TO THE BOTTOM THEREOF, A PUMP CONNECTED TO SAID WATER OUTLET CONDUIT, A DISCHARGE PIPE FOR CONVEYING DISTILLED WATER AND WHICH IS CONNECTED TO SAID PUMP, AN ELECTRIC MOTOR DRIVING SAID PUMP FOR WITHDRAWING DISTILLED WATER FROM SAID TANK AND DISCHARGING THE SAME UNDER PRESSURE THROUGH SAID DISCHARGE PIPE TO A POINT OF USE, A FAN DRIVEN BY SAID MOTOR FOR CIRCULATING AIR OVER SAID CONDENSER RADIATING FINS TO COOL THE SAME, SAID DISTILLED WATER DISCHARGED PIPE COMPRISING A T WITH A BRANCH LINE LEADING BACK TO SAID TANK FOR RETURNING DISTILLED WATER TO THE TANK, VALVE MEANS IN SAID BRANCH LINE, A PRESSURE REDUCER IN SAID DISTILLED WATER DISCHARGE PIPE FOR REGULATING THE WATER, PRESSURE THEREIN, AND PRESSURE GAUGE MEANS IN SAID DISCHARGE PIPE IN ADVANCE OF SAID PRESSURE REDUCER AND A SECOND PRESSURE GAUGE IN SAID DISCHARGE PIPE LOCATED BEYOND SAID PRESSURE REDUCER.
