A New or Improved Stove for Warming Rooms and for other Heating
purposes.
I, HENRY BRIDGWATER, of Springfield House, Dudley, in the County of Wor-
cester, Iron Merchant, do hereby declare the nature of this invention to be as
follows:-
My invention consists of a store the parts of which are constructed and com-
bined in the manner hereinafter described. The said stove is especially useful for
warning apartments but may also be used for other purposes such for example
as warming or heating liquids.
In constructing a stove according to my invention I make a chamber preferably
of fire clay or other earthy material, but I do not limit myself to any particular
materials. The said chamber may be made rectangular or of any desired orna-
mental shape. The said chamber is closed on all sides excepting at the bottom
which is open for the admission of air to support the combustion of the lamp em-
ployed as the source of heat. The chamber is supported preferably on four feet
the open bottom being a short distance from the floor of the apartment. Where
burning gas is the source of heat the gas is conducted by a pipe entering the open
hottom of the chamber the said pipe terminating in a burner or burners in the
lower part of the chamber. At one side of the chamber and near its top is a pipe
of sufficient size to carry away the vitiated air and products of combustion which
are conducted by the said pipe into a chimney or flue. Instead of a gas flame a
lamp burning either light or heavy oil may he employed as the source of heat or
any other combustible may he employed.
When the gas or other combustible is ignited a current of hot air rises to the
upper part of the chamber together with the products of combustion and heats the
sides and top of the chamber passing from the upper part of the chamber by
the pipe described into the chimney or flue and from thence into the atmosphere.
The air in the room in contact with the exterior of the chamber is expanded
and ascends giving place to another portion of air and a circulation is thus set up
by which the air of the room is raised to the required temperature. By means of
a thermometer in a distant part of the room the temperature of the air is indicated
and can be regulated by the stopcock or wick of the lamp or other regulator with
which the source of heat is provided. As no part of the air by which the combus-
tion of the lamp or fuel of the stove is supported enters the room the air of the
room is uncontaminated, and as the heat of the exterior surface of the stove is never
sufficiently high to decompose organic matter in the air, the said air never has the
burnt odour common to the air of rooms heated by ordinary stoves.
Vessels of water or other liquid placed on the top of the stove quickly become
heated sufficiently for many purposes.
Where it is desired to give the stove an ornamental appearance the stove proper

page_text: may be covered by an ornamental covering preferably perforated. This orna-
mental covering may be made of metallic or non-metallic material.

A New or Improved Stove for Warming Rooms and for other Heating
purposes.
I. HENRY BRIDGWATER, of Springfield House, Dudley, in the County of Wor-
cester, Iron Merchant, do hereby declare the nature of my invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :—.
My invention consists of a stove the parts of which are constructed and com-
bine in the manner hereinafter described. The said stove is especially useful for
warming apartments, but may also be used for other purposes such for example
as warming or heating liquids.
In constructing a stove according to my invention I make a chamber preferably
of fire clay or other earthy material, but I do not limit myself to any particular
materials. The said chamber may be made rectangular or of any desired orna-
mental shape. The said chamber is closed on all sides excepting at the bottom
which is open for the admission of air to support the combustion of the lamp em-
ployed as the source of heat. The chamber is supported either on feet the open
ttom being at a short distance from the floor of the apartment or the bottom may
rest on the floor and a side opening admit air to the body of the stove. Where
burning gas is the source of heat the gas is conducted by a pipe entering the open
bottom of the chamber the said pipe terminating in a burner or burners in the lower
part of the chamber. At one side of the chamber and near its top is a preferably
horizontal pipe of sufficient size to carry away the vitiated air and products of
combustion which are conducted by the said pipe into a chimney or flue. Instead
of a gas flame a lamp burning either light or heavy oil may be employed as the
source of heat; or any other combustible may be employed.
When the gas or other combustible is ignited a current of hot air rises to the
upper part of the chamber together with the products of combustion and heats
the sides and top of the chamber passing from the upper part of the chamber by
the pipe described into the chimney or flue and from thence into the atmosphere.
The air in the room in contact with the exterior of the chamber is expanded and
ascends giving place to another portion of air and a circulation is thus set up by
which the air of the room is raised to the required temperature.
Figure 1 of the accompanying drawing represents in back elevation; Figure 2
in side elevation: Figure 3 in front elevation and Figure 4 in vertical section a
stove for warming rooms and for other heating purposes constructed according
to my invention: Figure 5 represents in elevation and Figure 6 in vertical section
one of the atmospheric gas burners which I employ in the stove drawn to a large
scale.
The same letters of reference indicate the same parts in the several figures of
the drawing,
is the vertical chamber of fire clay or other earthy material constituting the
body of the stove. The said chamber or body a represented is of an oblong or

page_text: rectangular figure in plan but I do not limit myself to that figure nor to the
material of which it is made.
°
It will be seen by an examination of the drawing that the chamber or body a
rests on the floor of the apartment and is closed excepting at its bottom and at
one side near the bottom, the open side part being marked b. The open side part b
is for the admission of air to support combustion of the gas flames or other source
of heat employed at the base of the chamber or body a. The parts of the sides of
the body a uncut away constitute a base on which the stove is supported. Or the
side opening 6 may be dispensed with and the open bottom of the chamber a be
supported upon fect a short distance above the floor. I have represented the
source of heat in the stove as consisting of two Bunsen or atmospheric gas
burners c, c situated in the lower part of the chamber a and secured in the floor of the
apartment as represented in Figures 5 and 6 and connected with the gas supply;
air to mix with the gas to produce the combustible gaseous mixture passing into
the burner at the side holes c², c². .
b
A single Bunsen or atmospheric burner may be situated at the base of the stove
and for large stoves more than two burners may be employed.
Near the top of the chamber a and at the back thereof is a pipe connected with
the chimney or flue of the room or otherwise connected with the external air for
carrying away the vitiated air and products of combustion from the stove.
For igniting the burners in the base of the stove a key shaped hole or other
shaped hole is made in the front of the chamber which hole after the burners
have been ignited is filled with a plug so as to close the said hole air tight, air
entering the stove only at the side part 7 near the base. After the gas burners e, c
have been ignited a current of hot air rises in the upper part of the chamber a
together with the products of combustion and heats the sides and top of the cham-
ber, the said hot air and products of combustion escaping from the upper part of
the chamber by the pipe d into the atmosphere. By this heating of the upper
part of the chamber the air in contact with the exterior of the chamber is expanded
and ascends giving place to another portion of air and a circulation is thus set
up and the air of the room raised to the required temperature.
As no part of the air by which the combustion of the lamp or fuel of the stove is
supported enters the room the air of the room is uncontaminated and as the heat
of the exterior surface of the stove is never sufficiently high to decompose organic
matter in the air, the said air never has the burnt odour common to the air of
rooms heated by ordinary stoves.
By means of a thermometer in a distant part of the room the temperature of the
air is indicated and can be regulated by the stopcock or wick of the lamp or other
regulator with which the source of heat is provided.
•
Vessels of water or other liquid placed on the top of the stove quickly become
heated sufficiently for many purposes.
Where it is desired to give the stove an ornamental appearance the stove proper
may be covered by an ornamental covering preferably perforated. This ornamental
covering may be made of metallic or non-metallic material.
Although I have represented the source of heat as gas flames produced by
Bunsen or atmospheric gas burners yet I do not limit myself thereto as other
sources of heat as hereinbefore pointed out may be employed in place of gas flames
or a mixture of gas and air.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that I claim as my
invention:
The new or improved stove for warming rooms and for other heating purposes
herein before described and illustrated in the accompanying drawing, the said
stove consisting essentially of a vertical rectangular or other shaped chamber or
body made preferably of fire clay or other earthy material open at the bottom

page_text: or at the bottom and one side near the bottom at which open bottom or open
side near the bottom air enters the stove for supporting the combustion of the gas
flame or flames, oil lamp or lamps or other source of heat employed at the base of
the said chamber or body for heating the upper part of the stove the several parts
of the stove being arranged and working substantially as described and illustrated.
