I, PATRICK O'CONNOR, of Wavertree, near Liverpool, in the County of
Lancaster, Ironmonger, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE CONSTRUCTION OF GAS STOVES FOR HEATING AND
WARMING," to be as follows:-
My Invention relates, firstly, to improvements in portable gas stoves or
apparatus for heating water in baths and other vessels. Hitherto, in the appli-
cation of gas for raising the temperature of liquids, it has been usual to apply
the gas to the vessel containing the water, or to a supplementary vessel placed
alongside and communicating with the main body. By my Invention, how-
ever, contrary to all others, the stove or apparatus is almost entirely immersed
in the water, and the gas is conveyed thereinto by a 'flexible or jointed tube;
so that as soon as the desired temperature has been obtained, the said stove or
apparatus can be removed from amongst the water. The principal part
consists of an U, surpentine, coiled, or other suitably-shaped metallic casing,
exposing a large surface to the water for effective distribution of the heat.
The gas from the tube above referred to is burned at jets fixed in a T or other
bracket, by preference under a part of the apparatus formed into an arch,
and combustion is maintained by supply of air received at one end of the
apparatus, the products being carried through the apparatus to the other end,..
where by a small intercepting inverted cup situate just over the surface, they.

the escape of noxious effluvia into the atmosphere; and, secondly, to improve-
ments in gas stoves or apparatus for warming rooms, halls, conservatories,
and other apartments and buildings. Here the object is to expose a large
superficial metallic area for the radiation of heat; this is secured by the form
of stove or apparatus herein-after described, within the casing of which water
is made to circulate in every part, and, if desired, may circulate or be carried
through pipes or other conductors a considerable distance. The bottom
framing supports and communicates internally with a saddle boiler, from both
ends of which are water spaces carried vertically, resembling with the semi-
circular or arched communication on the top an inverted U. On the top
of this arch a water supply cistern or expansion head is placed, from which a
pipe is carried through one of the legs down near to the bottom. The gas
jets are applied under the saddle boiler, and as the bracket conveying the gas
is jointed, the lights may be used for illumination or any other purpose when
further heating of the stove is unnecessary. The products of combustion are
carried through a flue in one of the legs of the inverted U, and allowed to
escape over the surface of the water in the cistern or expansion head in a
similar manner to the discharge in the apparatus first herein described, or
any other absorbent may be used. Any steam generated in the apparatus is
carried off by a suitable pipe, and condensed in the water expansion head.
