Specification Accepted, 29th July, 1887.
I, JAMES GALLI, of 43 Mill Hill, Leeds, in the County of York, Steam, Gas, and
Hot Water Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention relates to certain improvements in gas stoves used for domestic
purposes, and has for its object the arrangement of the apparatus, so that the heat
and products of combustion, are distributed and utilized in a more efficient and
better manner than heretofore, whereby the quantity of gas burnt is considerably
reduced.
My invention consists in arranging around the oven of the stove, two casings one
outside the other, having chambers or passages between them. The chamber or
passage immediately next to the oven is used by means of suitable midfeathers or
partitions therein, to conduct the heat and products of combustion around the oven,
while the other chamber is filled with some non conductor of heat such as asbestos or
slag wool.
I also fix the stove upon a stand in which there is a circulating hot water boiler
supplied with water from a cistern. The heat after passing around the oven is
conducted around this circulating hot water boiler before escaping finally into the
atmosphere, whereby the heat is still further economised.
In order that my invention may be more clearly defined, I append a sheet of
drawings, in which Fig. 1 represents a longitudinal section of a gas stove
arranged according to my improved pattern, Fig. 2 a sectional plan, and Fig. 3 a
front elevation.
I fix the oven A which is made of sheet iron or other suitable material, in a
casing B leaving a chamber or passage C for the escape of the heat and products of
combustion, the casing B being fixed in the outside casing D, between which there is
another chamber E which I fill with a non conductor of heat such as asbestos
or slag wool. Below the burners F, which are of the usual atmospheric description,
and placed outside the oven A, I fix a circulating hot water boiler G, in the pedestal
or stand H, upon which the stove stands, the boiler G similarly to the oven A having

heat chamber, while the latter one is filled with a non-conducting material, and in
the stand H I also have a door, for the purpose of lighting the burners F, and the
inlet of air.
In the chamber or passage C I fix midfeathers or partitions K, which cause the
heat and products of combustion to rise up the sides of the oven A, on the top, and
then to descend down the back of same, through the pipe L into the chamber C, at
the underside of the circulating hot water boiler G, in which chamber there is a mid
feather or partition K' around the end of which, the heat and products of combustion
have to pass, before finally escaping through the opening M into the atmosphere.
Above the level of the boiler G and connected thereto by circulating pipes N I fix a
cistern O self filling or otherwise as required, the heated water being drawn, either
from the cistern O, or the circulating pipes N.
The pipe L connecting the chambers C and C¹ can be fixed either inside or outside
the stove, and should the stove be required without a hot water boiler G, the pipe L
discharges the heat and products of combustion directly out of the chamber C into the
atmosphere.
The upper portion of the stove which is used mostly for boiling pans, kettles, and
grilling, I construct in the ordinary manner.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed I declare that what I claim is :-
In a gas cooking stove, the distribution, and utilization of the heat by means of
chambers formed by casings, substantially in the manner as shewn and described.
In a gas cooking stove the application of a circulating hot water boiler, substantially
in the manner as shewn and described.
