of the Commissioners of Patents, with his Petition, on the 4th
March 1875.
I, RICHARD GEORGE, of Alma Road, Kentish Town, in the County of
Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN STOVES," to be as follows:-
This Invention relates to improvements in the arrangement and con-
struction of stoves, whereby the quantity and combustion of the fuel
employed can be regulated so as to determine approximately the length
of time required for its consumption, and also the temperature of the
room or chamber in which it is placed. For this purpose I construct a
metallic chamber of cylindrical or other suitable form placed upon legs
or other supports, the upper end of which is closed by means of a cover
and a sand, water, or other suitable joint.
At the lower part of the chamber a door is placed in communication
with the ash-pit or chamber below the fire-grate. The aperture to
supply air for combustion may cither be formed through the door or
otherwise into the ash-pit,

page_text: The metal chamber is lined with fire-clay or other refractory material
the interior of which is of taper or conical form, and in order to increase
or diminish the capacity of the combustion chamber I find it desirable
to make the fire-clay lining in rings, tubes, or section, so that the
position of the fire-grato may be altered with facility when required.
By raising the fire-grate the grate surface is diminished as well as the
capacity of the fire-chamber, owing to the conical form and stepped
surface of the interior of the chamber.
A pipe or passage is formed at a suitable height through the side of
the stove for the outlet of the products of combustion, and so as to
divide the inner chamber into a lower combustion chamber and the
upper reserve chamber for the fuel.
In order to charge the stove the cover is removed and a quantity of
ignited fuel or combustible material is placed on the fire-grate to be
ignited; the interior chamber is then filled with coke, charcoal, or other
similar fuel, the cover being securely closed over it; by opening the fire-
door the fuel below the top of the outlet passage rapidly assumes a
perfect state of combustion, the door is then closed and the necessary
quantity of air to support combustion is supplied through the small
aperture previously described.
The fuck in the combustion chamber supports the fuel above, and
prevents its ignition until it descends below the outlet pipe as the fuel
become gradually consumed.
For heating water, for generating steam, or for other purposes the
stove may be surrounded by or enclosed within a receptaclo containing a
water, arranged with inlet and outlet pipes as is well understood.
When required for warm ventilation I enclose the stove in a cylinder
or coil in communication with the outer atmosphere, such as or similar
to the arrangement described in the Specificaton of Letters Patent
granted to me, dated 11th October 1867, No. 2853, the outlet pipe is a
provided with a damper or throttle valve, to be fully opened before.
removing the cover to supply fresh fuel to prevent the noxious gases
entering the apartment in which the stove is placed.
