Improved safety thermostat system for electric beverage making device

Claim 1

In a beverage-making device of the type having a covered water container for storing a quantity of water for use, the water container having an exterior sidewall and being heated by a looped coil-type heating element arranged interiorly thereof, said heating element having a plurality of coil loops, wherein at least one loop of the coil extends around the interior of the water container near the sidewall thereof, and running thermostat means capable of activating said heating element responsive to water temperature changes sensed within said container to maintain the temperature of the stored water in the container at a predetermined value, the improvement comprising a safety thermostat arranged to be capable of de-activating said heating element upon sensing temperature at the exterior sidewall of said container in excess of said pre-determined value and a mounting means therefor, said safety thermostat being attached to said mounting means and disposed against the exterior sidewall of the container generally about at or below the midpoint height thereof and close to said at least one coil loop of said heating element, said safety thermostat being in series in an electrical circuit with said running thermostat whereby the running thermostat is capable of being overridden by the safety thermostat upon reaching a temperature in excess of said predetermined value to de-activate the heating element.
