ABSTRACT:
An improved coffee maker is disclosed. The coffee maker shuts off automatically when the level of coffee in the decanter drops below a certain point, or when the decanter is removed. A housing is provided with the conventional elements used to brew coffee. The invention further comprises a decanter platform biased upward by a helical spring, the platform engaging switches which control the flow of electrical current to the brewing and heating elements of the coffee maker. When the decanter is at least partially full, the decanter platform is depressed and the switches are biased to the "on" position. When the decanter is almost empty, the upward travel of the decanter platform shuts off the heating element switch. When the decanter is removed from the platform, the brewing mechanism is shut off.
