Claim 8

A distilling apparatus as claimed in claim 5 further comprising biasing means for biasing said valve to a closed position, said value including a rigid actuator connected between said thermostat and said valve for opposing said biasing means.

Claim 9

A distilling apparatus comprising: an evaporator including a liquid tank for charging with a liquid to be distilled having a removable top, said top defining an opening therethrough, means for heating the liquid within said tank, an exhaust chimney extending from said liquid tank including a first end connected with said opening, said exhaust chimney further including first and second concentrically mounted tubes wherein said first tube is a vapor outlet tube and said second tube is a tank inlet tube disposed within said first tube, venting means at a second end of said exhaust chimney providing access to the atmosphere for said tank inlet tube, a condenser connected with said exhaust chimney, said condenser including an outer tube connected with said first vapor outlet tube and at least one inner tube disposed therein, said at least one inner tube comprising a condenser inlet tube in communication with said tank inlet tube, a condensate outlet connected to said outer tube of said condenser, a liquid inlet connected to said condenser inlet tube to supply liquid to be distilled, a thermo-responsive valve mounted to control the flow of liquid in said liquid inlet, said thermo-responsive valve including a thermostat mounted substantially centrally within said condenser inlet tube and connected to operate said valve as a function of temperature of the liquid within said condenser inlet tube.

Claim 10

A distilling apparatus comprising: an evaporator including a liquid tank for charging with a liquid to be distilled having a removable top, said top defining an opening therethrough, means for heating the liquid within said tank, an exhaust chimney extending from said liquid tank including a first end connected with said opening, said exhaust chimney further including first and second concentrically mounted tubes wherein said first tube is a vapor outlet tube and said second tube is a tank inlet tube disposed within said first tube, venting means at a second end of said exhaust chimney providing access to the atmosphere for said tank inlet tube, a condenser connected with said exhaust chimney, said condenser including an outer tube connected with said first vapor outlet tube and at least one inner tube disposed therein, said at least one inner tube comprising a condenser inlet tube in communication with said tank inlet tube, a condensate outlet connected to said outer tube of said condenser, a liquid inlet connected to said condenser inlet tube to supply liquid to be distilled, a thermo-responsive valve mounted to control the flow of liquid in said liquid inlet, said thermo-responsive valve including a thermostat mounted substantially centrally within said condenser inlet tube and connected to operate said valve as a function of temperature of the liquid within said condenser inlet tube.

Claim 11
