AN IMPROVED STOVE FOR WARMING AND VENTILATING PURPOSES
Year: 1884

page_text: I RICHARD FRANCIS BOWLES of 86 Cambridge Street, Westminster in the
county of Middlesex do hereby declare the nature of my Invention for AN
IMPROVED STOVE FOR WARMING AND VENTILATING PURPOSES, to be as follows :—
I make, of any material, but by preference of a fire resisting earthenware, a case
generally rectangular in form; the interior of which is divided into three chambers
by means of two upright vertical divisions or partitions.
The centre chamber which lies between and is formed by the two upright
vertical divisions, and which is much larger than either of the two outer chambers,
I fill with a large number of small tubes, which may be of any shape, placed
horizontally in rows one row above another, the two ends of each tube passing
through and being fixed in each of the two vertical partitions respectively, and the
interior of the tubes communicating with the interior of each of the two outer
chambers like the tubes of the tubular boiler of a locomotive engine, (which cause
the firebox to communicate with the smokebox,) and as in the above case the
tubes are placed alternately as near to each other as they can conveniently lie,
whilst allowing a sufficient space all round them for the circulation of air.
One of the outer chambers, called the combustion chamber may be entirely
closed, with the exception of a small door in front & pipes fitted to admit air as
hereafter described; or it may be fitted with an ordinary open grate with an
ordinary blower. In this chamber heat is produced by the combustion of gas, oil,
coal or any kind of fuel. The products of combustion passing through the interior
of the tubes into the chamber at the other end of the tubes beat them, and are
conveyed by means of a pipe into an ordinary flue, chimney or outlet.
Air from the room, or the outer air, (either or both at will,) is admitted, if the
stove is not used with an open grate, through taps fitted in pipes at the bottom of
the combustion chamber and in a similar way either or both at will is admitted
into the lower part of the central or tube-chamber, and this air circulating round
the beated tubes becomes heated and passing up between them escapes into the
room through an opening made for the purpose at the top of the stove.
The stove is made in two portions, an upper and a lower, so that extra horizontal
sections each containing tubes with portions of the two outer chambers exactly
similar in plan to the body of the stove and corresponding with the parts to which
they are to be fitted, (but without either top or bottom,) can be inserted if required

and by this means the stove can be increased to any reasonable size, and the
greatest possible amount of the heat produced conveyed into the room, instead of
being wasted by being carried away up the chimney.
The shape of the exterior case or stove may vary in form to suit the nature of
the position, appliances, furnaces or burners for the combustion of the fuel used,
and the tubes, if long, can be constructed of such shape as to touch, and support
each other at intervals, without interfering with the free circulation of the air
round them, if required.
By means of this stove all the products of combustion are excluded from the
room and fresh warm air can be constantly admitted keeping the atmosphere
pure & healthy.

I RICHARD FRANCIS BOWLES of 86 Cambridge St Westminster in the county of
Middlesex Esq do hereby declare the nature of my Invention for AN IMPROVED
STOVE FOR WARMING AND VENTILATING PURPOSES and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :—
I make of any material but by preference of a fire resisting clay or earthenware,
such as is usually used a case generally rectangular in form as A in fig I. the
interior of which is divided into three chambers B. C. D fig 2 by means of two
upright vertical divisions or partitions E & F. fig 2 The centre chamber C which
lies between and is formed by the two vertical partitions and which is much larger
than the two outer chambers I fill with a number of small tubes, which may be
of any shape, placed horizontally in rows one row of each tube passing through
and being fixed respectively in each of the two vertical partitions E & F in fig 2
and the interior of the tubes communicating with the interior of each of the two
outer chambers like the tubes of a tubular locomotive engine boiler (which cause
the fire-box to communicate with the smoke-box) and as in the above the tubes
are placed as near each other as they can conveniently lie while allowing a
sufficient space all around them for the circulation of air.
One of the outer chambers B. fig 2 called the combustion chamber may be
entirely closed with the exception of a small door in front L fig 2 and pipes fitted as
hereafter described or it may be fitted with an ordinary open grate.
Heat is
produced by the combustion of gas, oil, coal or any kind of fuel.
The products of combustion passing from the combustion chamber through the
tubes backwards and forwards in the direction of the arrows fig 2 or by dispensing
with the stops H. H. in the outer chambers directly through all the tubes into the
chamber D. fig 2 at the other end of the tubes heat them and are conveyed by
means of a pipe into an ordinary chimney or other outlet.
Air from the room or outer air, (either or both at will,) is admitted, if the
stove is not used with an open grate, through taps fitted in pipes inserted in the
bottom of the combustion chamber B. and in a similar manner, either, (or both at
will) is admitted into the lower part of the central or tube-chamber C at arrow K
or other point and this air circulating round the heated tubes becomes heated and
passes into the room through openings G made for the purpose in the top of the
stove or the whole of the top of the central or tube chamber may be made to take
off like a lid.
The stove can be made in two portions an upper and a lower so that, for the
purpose of increasing its size, extra horizontal sections, each containing tubes with
portions of the two outer chambers exactly similar in plan to the body of the
stove and corresponding with the parts to which they are to be fitted but without
either top or bottom, can be inserted if required.
The shape of the exterior of the case or stove may vary in form to suit the
nature of the position appliances furnaces or burners for the combustion of the fuel
used and the tubes if long can be constructed of such shape as to touch and support

page_text: each other at intervals without interfering with the free circulation of the air
around them if necessary.
Having now particularly described and ascertained the nature of said Invention
and in what manner the same is to be performed I declare that what I claim is
I wish it to be understood that I claim as features of novelty.
1. The peculiar arrangement above described which causes the products of
combustion to pass through and heat tubes laid horizontally whilst the air of the
room or outer air is made to pass upwards around their heated outer surfaces, and
a current of hot & fresh air is produced for warming & ventilating purposes;
while the products of combustion pass away & are entirely excluded from
the room.
2. The construction in earthenware of an apparatus made on the principle of the
tubular boiler of a locomotive engine, with furnace, horizontal tubes and smoke-box
or flue.
3. The construction in sections above described which admits of adding to the
stove & thus increasing the heating surface at will.
In witness whereof I the said Richard Francis Bowles have hereunto set my
hand and seal this 14th day of March 1885.
