Abstract
Abstract A combined food warmer and beverage dispenser includes a generally parallelepipedal boiler, adapted to contain water, and associated means to heat the water. Suspendedly mounted in one end of the boiler and kept warm by the water therein are one or more beverage urns. The other end of the boiler contains a food warming chamber, extending into the boiler and jacketed by boiler water, said chamber including an access opening occupying most of the face of this end of the boiler. The same face which contains the access opening also contains a plurality of dispensing valves. One of these valves drains hot water from the interior of the boiler for beverage use. Another valve is connected to a beverage urn and drains previously prepared hot beverage from it. Thus, a user standing at one location can obtain hot beverage, hot water and/or warm food.

Total Claims: 6
Claim 1
Independent Claim
217 words
A combined food warmer and beverage dispenser comprising; a. a generally parallelepipedal boiler including a top, a bottom, sides, a proximal end and a distal end, said boiler being capable of holding a body of water; b. means for heating water present in said boiler; c. at least one beverage urn mounted within said boiler proximate the distal end thereof and spaced apart from the bottom and sides thereof, to permit circulation of hot water thereabout, said urn including an outlet; d. a food warming chamber located at the proximal end of said boiler including a generally rectangular access opening occupying substantially the full width of said proximal end and extending transversely from the top of said end toward the bottom, said chamber extending into the boiler toward the distal end thereof; e. a first dispensing valve located in said proximal end adjacent the warming chamber access opening, adapted to draw water from said boiler; f. a second dispensing valve also located in said proximal end adjacent the warming chamber access opening; g. conduit means connecting the outlet of said urn and said second dispensing valve; and whereby a single unit is provided which permits dispensing of a beverage, dispensing of hot water and unloading of the contents of the warming chamber from a single access location.
