Abstract

Apparatus for heating water over an open fire comprises a kettle having a substantially flat bottom and an upstanding perimeter sidewall. Two openings are provided in the upper portion of the sidewall of the kettle. A water inlet tube extends through one of the openings and has an open, inner end that is positioned in the lower portion of the interior of the kettle. The open, outer end of the water inlet tube is positioned outside the kettle and is adapted to have aliquots of cold water poured into the open end so that the cold water will flow into the kettle through the water inlet tube, with the cold water entering the lower portion of the interior of the kettle. A water outlet tube extends through the other opening and has an open, inner end that is positioned in the upper portion of the interior of the kettle. The open, outer end of the water outlet tube is positioned outside the kettle and forms a hot water spout on the outside of the kettle. As aliquots of cold water are poured into the water inlet tube, similar sized aliquots of hot water are dispensed from the kettle through the water outlet tube. The kettle remains full of water at all times, and the cold water is rapidly heated in the bottom portion of the kettle. The heated water rises to the upper portion of the kettle as additional cold water is added to the kettle.

Apparatus for heating water over a heat source, said apparatus comprising

a kettle for containing the water to be heated, said kettle having a bottom and a perimeter sidewall that extends upwardly from said bottom so as to have an open upper edge;
two openings in the upstanding sidewall, said openings being located at a vertical distance from the upper edge of said sidewall that is no greater than about one-third of the distance between the upper edge of said sidewall and said bottom of said kettle;
first and second grommets made of a polymeric material, each grommet being fit inside one of the respective openings in said sidewall;
a water outlet tube fit snugly through the first grommet so that the water outlet tube makes a watertight seal with the first grommet and the first grommet makes a watertight seal with the respective opening in said sidewall, said water outlet tube having an open, inside end located inside said kettle at a distance from the upper edge of said sidewall that is no greater than about one-third of the distance between the upper edge of said sidewall and said bottom of said kettle;
and
a water inlet tube fit snugly through the second grommet so that the inlet tube makes a watertight seal with the second grommet and the second grommet makes a watertight seal with the respective opening in said sidewall, said water inlet tube having an open, inside end located inside said kettle at a distance from the upper edge of said sidewall that is at least about two-thirds of the distance between the upper edge of said sidewall and said bottom of said kettle, said water inlet tube further having an open, outside end located outside said kettle and oriented so that the open, outside end faces generally upwardly so that water can be poured into said open, outside end.
