Abstract
Abstract A hot beverage dispensing means having first, second, and third reservoirs; one below the other in the order listed. The first reservoir is watertight except for one outlet at the bottom thereof which fills the second reservoir up to the level of said opening. A two-position valve in its lower position allows water to flow from the second to third reservoir where it is heated by a heater activated when said valve is in its lower position. Movement of the valve to its upper position in response to a thermostatic indication deactivates the heater and release the heated water into a cup.
