Improvements in and relating to Heating Apparatus.
I, WILLIAM FUNNELL, of 9 Blackman Street, Brighton, in the County of
Sussex, Hot Water Engineer, do hereby declare the nature of this invention to be
as follows:-
My invention relates to apparatus for heating water for warming apartments by
means of a circulation through coils or pipes or the like and has for one of its chief
objects to provide an improved boiler, adapted for use in connection therewith but
applicable also for other purposes, wherein the temperature of the said water can
be raised in an economical manner; the heat of any ordinary fire place, which
with ordinary boilers otherwise goes to waste against the wall at the back and up
the chimney, being preferably utilized for that purpose. My said boiler can be
economically applied to any of the present systems of warming by hot water.
According to my invention I so construct my improved boiler that it is capable
of being fitted to any stove of ordinary or other construction, including registers or
slow combustion stoves with or without shaped knee backs or sides or the like, in
such a manner as to take the place of the usual flue formed in the brickwork at
the back or side of the said stove, and to be indistinguishable to the occupants of
the room or apartment from the usual fire back of the stove.
For this purpose
I prefer to construct the said boiler with three sides or back and sides or crescent-
shaped and with one or more upright internal flues or passages with arched
horizontal passages under. In fixing, the boiler is placed vertically or on end and
is built into the fire place as a part of any ordinary stove leaving the ordinary
space for the fire as the improved boiler takes the place of the usual back. The
space (ordinary fire space) formed by the hollow or concave side of the boiler is
preferably parabolic or such as to retain the products of combustion prior to their
passing up the chimney and to permit the passage of the ordinary amount of heat
into the room. When the boiler is provided with one or more internal flues, which
may correspond in plan to that of the water chamber, form, preferably in the
lower part of the foremost wall or walls of such boiler, one or more arches or
passages leading into the said flue or flues so that the products of combustion will
gain access therethrough into the flue or flues, and from thence to the chimney.
I am thus able to ensure extra heating surfaces from the ordinary fire and to
utilize to the utmost the heat of the fire, inasmuch as, in a fireplace on the
Rumford principle, for example, the fire will first heat the room in the ordinary
way and the foremost wall of the boiler, and then playing direct through the one
or more arches or passages leading into the internal flue or flues, will heat the
boiler on all sides of the said flue or flues during its passage up the latter, thus
utilizing the heating effect communicated by the fire by conduction to the utmost.
I prefer to construct my improved boiler of wrought iron with welded joints, but
I do not confine myself to that material or method of manufacture, as I may
employ steel, copper, or other suitable material with riveted or other joints.
Besides providing a boiler without in any way interfering with the appearance
or the front of the fire and the obtaining of additional heating surface, my
invention is advantageous in that only a short length of brick flue above the stove
or boiler is required sufficient to allow for the fitting of a drawout or other damper
to enable the draught to be checked or regulated; moreover special skilled labour

page_text: can be dispensed with and the setting effected by any ordinary workman of average
intelligence.
By utilizing the ordinary register or slow combustion grate or stove usual in a
drawing, dining, or billiard rooin, hall, stable, servants' room, pantry or any other
room or place to heat the whole or part of any building or buildings or one or
more rooms or apartments in, or portions of the same, or any adjoining buildings,
a very considerable saving of fuel is effected, and the trouble and inconvenience
arising from the use of a separate furnace and stoke-hole are obviated.
Although I have herein before described my improved boiler as having one
internal flue or passage dividing it internally into, or nearly into, two distinct
water ways or spares, it is obvious that I can employ two or more of such, either
in the depth or width or both, or other suitably shaped flues and that I can also
somewhat modify the shape of the outer shell thereof.
The hot water circulating pipes may as hereinbefore mentioned be on any of the
present or other suitable systems of heating, and may be arranged in any well-
known or suitable manner.
It will be obvious that my improved boiler might be advantageously employed
in place of the ordinary saddle and other boilers in hot water installations.

1, WILLIAM FUNNELL, of 9 Blackman Street, Brighton, in the County of
Sussex, Hot Water 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 :-
My invention relates to apparatus for heating water for warming apartments by
means of a circulation through coils or pipes or the like and has for one of its chief
objects to provide an improved boiler, adapted for use in connection therewith but
applicable also for other purposes, wherein the temperature of the said water can
be raised in an economical manner; the heat of any ordinary fireplace, which
otherwise goes to waste against the back and up the chimney, being utilized for
that purpose. My said boiler can be economically applied to any fire or systems
of warming by hot water.
In the accompanying drawing
Figure 1 is a side elevation,
Figure 2 is a vertical central section, and
Figure 3 is a sectional plan showing one form of my improved boiler.
Like letters indicate corresponding parts throughout the drawing.
a is the boiler which is so constructed as to be capable of being fitted to any
stove of ordinary or other construction including registers or slow combustion,
independent, or other stoves with or without shaped backs or sides or the like, in such
a manner as to take the place of the usual back formed in brickwork or otherwise
around the said stove, and to be indistinguishable to the occupants of the room or
apartment from the usual fire back or register of the stove.
For this purpose
I may construct the said boiler a shaped as shown or otherwise with an internal
flue or passage a', and a horizontal passage a* under or through the water
chamber a. is a flue box, fitted with a damper b'.
In fixing, the boiler is placed vertically or on end and may be built in with the
fireplace as a part of the stove leaving the ordinary space for the fire as the
improved boiler takes the place of the usual back. The space (ordinary fire

page_text: space) formed by the hollow or shape of the boiler is such as to utilize the
products of combustion and to allow the ordinary appearance and amount of heat in
the room.
I thus secure extra heating from the ordinary fire, utilizing to the utmost the
heat thereof, inasmuch as it will, in addition to passing to the room in the ordinary
way, heat the foremost wall of the boiler, and the fire then playing direct into the
passage a through or under the water chamber a leading to the internal flue a¹
will heat the faces of the water chambers a³ and a³ of the boiler a all around the
said flue during its passage up the latter, thus utilizing the heating effect of the fire
to the utmost without any heat going to waste in the wall or back.
I prefer to construct my improved boiler of wrought iron with welded joints,
but I do not confine myself to that material or method of manufacture, as I may
employ steel, copper, or other suitable material with rivetted or other joints.
Besides providing a boiler without in any way interfering with the use or
appearance of the fire and besides the obtaining of additional heating surfaces, my
improved boiler is advantageous in that no brick flue is necessary, or even where
the metal flue b is not used, only a short length of brick flue above the stove or
boiler is required sufficient to allow for the fitting of the damper to enable the
draught to be regulated.
By utilizing the ordinary grate or stove that is usually fitted or placed in a
drawing, dining, or billiard room, hall, stable, servants' room, pantry or any other
room or place, to heat the whole or part of that and in addition any one or more
rooms or apartments in, or portions of, the same or any adjoining buildings or
conservatories and the like, a very considerable saving is effected in the quantity
of iuel used as compared with that hitherto necessary for the same purposes and
the trouble and inconvenience arising from the use of a separate furnace and
stoke-hole are obviated.
Although I have herein before described my improved boiler as having one
internal flue or passage dividing it internally into, or nearly into, two water ways
or spaces, it is obvious that I can employ two or more of such, either in the depth
or width or both, or other suitably shaped flues and that can also somewhat
modify the shape of the outer or other faces thereof. Two or more flues or other
passages may likewise be provided with three or more water chambers and
additional flue or flues or flue boxes to gain extra heating surface.
The hot water circulations may, as herein before mentioned, be on any of the
present or other suitable systems of heating, and may be arranged in any convenient
manner.
It will be obvious that my improved boiler might be advantageously employed
in place of the ordinary saddle and other boilers in hot water installations either
with or without any special fire or stoke hole.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
The improved beating apparatus constructed substantially as described with
reference to the accompanying drawing.
