page_text: I FREDERICK ROBERT EDWARD BRANSTON of 3 Crooked Lane in the City of
London Engineer do hereby declare the nature of this invention to be as follows:-
This Invention has for its object an improved gas or liquid fuel stove.
In my improved gas stove there is a central gas burner, it may be an air gas burner,
but preferably I employ an Argand burner with a chimney. Over the chimney I
arrange a helically coiled metal tube, in such a manner that the coil becomes heated
by the products of combustion rising from the burner. The coiled tube is open at the
ends and consequently a current of heated air ascends through it. This hot air is
delivered into a larger vertical pipe ascending to the top of the stove. This pipe
at its lower end near where the coiled tube enters it has an elbow passing to the
exterior of the stove and connected it may be with a passage by which air may be
drawn from the outside. This air becoming admixed with the hot air issuing from the
spiral or coiled tube and being urged forward by it ascends and escapes into the room.
The gas burner with the coiled tube and the vertical pipe above are all contained
within a cylindrical casing which forms a portion of the exterior heating surface of
the stove.
The hot products of combustion from the burner rise up within this casing and at
the top they pass by two lateral passages diametrically opposite into two other vertical
pipes one on either side of the central casing and by these they descend into the base
of the stove where they deposit any moisture which may be condensed and then escape
by an aperture provided for the purpose.
Sometimes in place of burning gas in this stove I make use of mineral oil or other
liquid fuel.
The construction of this stove is very simple; a single casting forms the base or
foot, it has three sockets in it, a central socket to receive the main body or furnace
casing and two lateral sockets for the ends of the descending tubes. The top of the
stove is similarly formed and the whole is bound together by vertical bolts passing
through the end castings and receiving nuts upon their extremities.

page_text: I, FREDERICK ROBERT EDWARD BRANSTON of 3 Crooked Lane in the City of
London, 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 has for its object an improved gas or liquid fuel stove.
In my improved gas stove there is a central gas burner, it may be an air gas
burner, but preferably I employ an Argand burner with a chimney. Over the
chimney I arrange a helically coiled metal tube, in such a manner that the coil
becomes heated by the products of combustion rising from the burner. The coiled
tube is open at the ends and consequently a current of heated air ascends through it.
This hot air is delivered into a larger vertical pipe ascending to the top of the stove.
This pipe at its lower end near where the coiled tube enters it has an elbow passing
to the exterior of the stove and connected it may be with a passage by which air may
be drawn from the outside. This air becoming admixed with the hot air issuing from
the spiral or coiled tube and being urged forward by it ascends and escapes into the
room.
The gas burner with the coiled tube and the vertical pipe above are all contained
within a cylindrical casing which forms a portion of the exterior heating surface of
the stove.
The hot products of combustion from the burner rise up within this casing and at
the top they pass by two lateral passages diametrically opposite into two other vertical
pipes one on either side of the central casing and by these they descend into the base
of the stove where they deposit any moisture which may be condensed and then escape
by an aperture provided for the purpose.
Sometimes in place of burning gas in this stove I make use of mineral oil or other
liquid fuel.
The construction of this stove is very simple; a single casting forms the base or
foot, it has three sockets in it; a central socket to receive the main body or furnace
casing and two lateral sockets for the ends of the descending tubes. The top of the
stove is similarly formed.
In order that my said invention may be most fully understood and readily carried
into effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation of a stove constructed in accordance with my invention.
Figure 2 is a vertical section of the same.
Figure 3 is also a vertical section and shows a modification.
A A is the burner, that in Figure 1 is of the Argand type and it is provided with
a chimney as is usual with burners of this sort.
The burner in Figure 3 is of the air

page_text: In some cases where gas is not easily obtained I substitute for these burners a
liquid fuel burner of any suitable well known construction. The burner is placed
centrally within a cylindrical casing B, and this casing is connected at the top and
bottom with two vertical pipes CC parallel to the casing B. These are all held
between two castings D and E. D is the base casting; it is closed at the bottom
except where the gas pipe passes through it and a small space left around the gas
pipe to allow any water resulting from condensation to drain out into a pan F. Three
sockets are formed in the upper part of the base casting to receive the lower ends of
the casing B and pipes CC. The top casting E is similarly formed but with the
sockets on its under side.
The structure may be bound together by bolts, but if the parts B and C are well
fitted to the sockets this will not be required.
G is a pipe having an elbow bend at its lower end by which it is fixed to the side of
the casing B, so that the air outside the stove has free access with the interior of the
pipe G. At its upper end this pipe G passes through a hole in the centre of the top
casting E. His a small coiled tube inserted at its upper end into the pipe G near
the elbow and centrally over the burner A. This tube H passes down, and its lower
end is within the base casting D, it is open so that the heated air from the interior of
the stove ascends by it into the pipe G.
In the front of the casing B a door B¹ is provided to give access to the burner A;
this door may have glass fitted to it through which the flame will be visible.
Immediately beneath the door there are perforations B B in the casing B which
allow air to enter in a small quantity. The air circulates round and round within the
stove; upwards in the casing B, then laterally within the top casting and descends
therefrom into the base by the pipes CC. From the base the current again rises
through the casing B, and so on. A small quantity only of the heated air ascends by
the tube H, and this enters the pipe G in a highly heated state, it ascends rapidly and
induces a current of air from outside the stove entering by the elbow at the lower
end of the pipe G and escaping into the room at the upper end of this pipe.
It is obvious that stoves may be made with but one descending pipe C but such
stoves will be less efficient.
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. In a stove the combination of a burner A; the cylindrical casing B; the vertical
pipes CC; and the top and bottom castings F and D each with three sockets
substantially as described.
2. In a stove the combination of a burner A; the cylindrical casing B ; the vertical
pipe or pipes CC; top and bottom castings F and D, the tube H and the pipe G
passing to the exterior of the stove substantially as described.
3. My improved gas or liquid fuel stove substantially as described.
