ABSTRACT:
An expansion thermostat adapted for regulating the temperature of a cooking surface. One end of the cooking surface is secured at one end of a container. Mounted to the other end of the container is a switch which controls the heat. When the cooking surface is heated, the cooking surface expands causing the other end of the cooking surface to release the switch. Releasing the switch turns off heat to the cooking surface. As the cooking surface cools, the switch is pressed. Pressing the switch turns on heat to the cooking surface. The heat to the cooking surface is thus cycled to provide a substantially constant cooking temperature.
