do hereby declare the nature of this invention to be as follows:-
J
This Invention relates to Improvements in that class of Stoves which have an
outside Casing or Shell, between which and the inside one which contains the fire,
there is an annular space into which the cold air is admitted and which by passing
through the enclosed space is heated to a high temperature, and is then conducted by
pipes or passages to any place it is desired to warm.
The principal feature of my Invention consists in making the inside casing which
contains the fire of a single piece of fire clay, which I usually make cylindrical in
section with openings in the side, at the top and bottom for the admission of fuel
and air.
The outside casing of the Stove I usually make of Fire Brick but above the fire
clay shell and forming a continuation of it I put a casing of Iron into which the
chimney is fitted. The fire clay Stove between the openings is encased in Stout Iron
Bonds and the top of the Air Chamber is covered with a Stourbridge Fire Clay
Square.

shire 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 Improvements in that class of Stoves which have an
outside casing or shell, between which and the inside one which contains the fire
there is an annular space, into which the cold air is admitted, and which by passing
through the enclosed space is heated to a high temperature and is then conducted by
pipes or passages to any place it is desired to warm.
The principal feature of my Invention consists in making the inside casing which
contains the fire of a single piece of fire clay, which I usually make cylindrical in
section with openings in the side, at the top & bottom for the admission of fuel and
air. The outside casing of the stove I usually make of Fire Brick but above the fire
clay shell and forming a continuation of it I put a casing of iron into which the
chimney is fitted, and in order that my said Invention may be more fully understood
I have appended hereunto a sheet of explanatory drawings.
it.
Fig. 1 shows a section and Fig. 2 a front elevation of the Stove as I prefer to make
1 is the cylindrical fire clay casing made of one piece of fire clay in which the
fire burns, the fuel being put in through the fire hole 3 and the draught admitted through
the opening 4, the quantity of which can be regulated by the sliding door 5. On the
top of the Fire Clay Casing 1 a sheet Iron bonnet of casing 6 is fitted, in which the
pipe 7 is fastened which forms a chimney for taking away the products of combustion.
The fire clay cylinder 1 is surrounded by a Brickwork casing 8 which I usually build
square and large enough to leave an annular space through which cold air (usually
brought from the outside of the building) through the pipe 9 circulates.
As the air becomes heated it rises, and passing up through the stove is conveyed
away by one or more pipes 19 to any chamber it is desired to warm. The top of the
stove is covered in by the fire square 10 and the concrete 11.
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
1. Making a Stove of the kind described above, with a fire clay chamber in which
the fire burns, from one solid piece of fire clay thereby making the Stove much more
durable and efficient.
