MENTS IN STOVES."
"IMPROVE-
The object of this Invention is to provido efficient means for heating a current
of air passed through the centre of the mass of fuel in pedestal and other stoves,
and for facilitating the removal from the stove of the clinkers and ashes formed
therein.
In carrying out my Invention I preferably construct a stove by building up a
series of annular rings of iron gilled externally, so as to obtain a large heating
surface, the gills sloping upwards and outwards the better to carry off the heat.
The base of the stove is fitted with a combined dead plate and grating to support
the fuel, and the grating is formed with a central aperture to allow of a pipe
passing vertically through the stove for conveying a current of heated air to tho
apartment to be warmed.
This combined grating and dead plate is so arranged with respect to the sliding
or other door by which the draught through the fuel is regulated as to prevent any
of the fuel from falling into the ash pit, while it allows of the easy removal from
the stove of the ashes and the clinkers.
As already stated, a current of air is caused to pass through the centre of the
fuel by means of a vertical pipe of novel construction. This pipe I construct of
cast iron surrounded by a casing formed of a series of rings of plumbago, fire clay,
or its equivalent placed one upon the other, by which casing the iron pipe is
protected from the great heat concentrated in the central portion of the stove.
The plumbago or fire clay casing being constructed in rings or short sections is
capable of a variable expansion, thus avoiding risk of breakage. I preferably protect
the lower part of the central pipe by two or more rings or sections of plumbago,
and the upper part of the pipe by rings of fireclay or its equivalent.

page_text: In some cases it may be desirable to form the sections of plumbago or fire clay
with grooves and flanges, which will serve to lock the sections together, while
allowing of their independent expansion and contraction.
By washing the iron pipe with gannister I am enabled to provide a coating
between the pipe and the plumbago or fire clay casing which will still further
protect the metal from injury by overheating. The stove is provided at top with
a gilled covering plate, preferably dome shaped, having a central aperture for the
passage of the hot air pipe. The stove is also fitted at the upper part with a
feeding door and smoke flue. The central air pipe is preferably connected with a
pipe drawing in fresh air from outside the room to be licated.
When the air of the room itself is drawn through the central pipe the lower end
of [the said pipe is supported by an annular rim or flange on the bottom plato,
which is centrally perforated to allow of the free passage of the air through the
stove.
By this sectional construction of stove all the parts may be speedily and easily
removed for inspection or repair.
The external heating capacity of the stove is not affected by the use of the
central pipe, which pipe most advantageously reduces the quantity of fuel required
to charge the stove. By properly proportioning the belt of fuel in this arrange-
ment great economy is secured, and the heating power of the apparatus is increased
by one third.

"IMPROVE- 2
This Invention relates, firstly, to improved means for conveying a current of
fresh air through the mass of fuel in pedestal and other stoves, whereby the
heating capacity of the stove will be greatly increased, and the intense heat
generated in the centre of the stove will be utilized; and, secondly, to a special 3
construction and arrangement of combined grating and dead-plate for supporting
the fuel in stoves, whereby the removal of the clinkers and ashes formed therein
is facilitated.
"
gill
In carrying out my Invention I preferably adapt it to what are known as
stoves," which I construct by building up a series of rings of iron gilled externally, 3
so as to obtain a large heating surface, the gills sloping upwards and outwards the
better to diffuse and carry off the heat; but the gilling of the stove is not essential
to the success of my improvements.
In the accompanying Drawing Fig. 1 is a vertical section of a gill stove con-
structed as above described and fitted according to 'my Invention with a central
warm air pipe and a combined grating and dead plate, Fig. 2 is a plan view of

page_text: the stove, Fig. 3 is a front elevation thereof, and Fig. 4 is a horizontal section of
the same taken on the line a, a, of Fig. 3. The same letters of reference indicate
like or corresponding parts.
In these Figures A is the pedestal gill stove built up of a series of rings of iron a
having gills radiating from their circumference in an upward and outward direction,
by which construction I have found that a great amount of heat is given off into
the apartment to be warmed.
The top of the stove is fitted with gilled covering plate or casting a', preferably
dome-shaped, and having a central aperture to allow of the pure warm air entering
the apartment through the vertical pipe B, which is placed centrally of the mass
of fuel within the stove. The stove is also fitted at the upper part with a feeding
door A¹ and a smoke flue A².
The pipe B is constructed of cast iron, and is encased by a series of rings or
sections C, C, of plumbago, fireclay, or equivalent_fire-proof material, such rings
being placed one upon the other, as shown in the Drawing. Attempts have been
made to heat a current of air by means of metal pipes passing through the fuel,
but such attempts have proved failures owing to the pipes being rapidly destroyed
by the action of the fire.
By means of this fire proof casing however the iron pipe B is effectually
protected from the great heat developed in the central portion of the stove, which
heat has hitherto been only partially utilized for warming apartments and
buildings.
The plumbago or fire-clay casing C being constructed in rings or short sections
is capable of a variable expansion and contraction, thus avoiding risk of breakage,
and facilitating renewal of worn out sections when necessary.
I preferably protect the lower part of the central pipe B, where the heat is
greatest, by two or more rings or sections of plumbago, and the upper part of the
pipe by rings of fireclay or its equivalent.
The rims of the said rings or sections C, C, may be plain and smooth, so as to
touch closely when placed one upon the other, but I preferably form them with
interlocking grooves and flanges, which will serve to hold the sections in position,
while at the same time allowing of their independent expansion and contraction.
By washing the iron pipe B with gannister I am enabled to provide a fireproof
coating between the metal pipe and the plumbago or fire-clay casing C, which will
still further protect the metal from injury by overheating.
The fuel is supported upon a combined grating and dead-plate D (see Figures 1
and 4), and this grating I form with an aperture to allow of the passage of the
central pipe B, as shown in the Drawing.
This combined grating and dead plate is so arranged with respect to the sliding
or other door E, by which the admission of air to the fuel is regulated as to
prevent any of the fuel from falling into the ash-pit, while it allows of the easy
removal from the stove both of the clinkers and ashes above and below it
respectively.
F is the bottom plate, onto which the ashes fall, and to this plate are secured
the feet, on which the stove stands. This plate F is made with an aperture of
circular form, and the lower end of the pipe B will rest around a flange or in a
recess formed around said aperture, when the air passing upwards through the
pipe B is derived from the room or building in which the stove is placed. But
should it be desired to draw in air to be warmed from the outside of the room or
building, the lower end of the pipe B will preferably rest within a recess or around
a flange formed round the aperture in the combined grating and dead-plate, as
shewn in Fig. 1, and a pipe communicating with the outer air will be led
through the opening in the bottom plate F, and will abut closely against the
underside of the combined grating and dead-plate, or such connection may be
effected in any other well known or suitable manner.
In stoves of small size the mass of fuel is not of sufficient bulk to necessitate the
employment of the central warm air pipe, and to such stoves I propose merely to

page_text: apply my improved arrangement of grating and dead-plate, which will then be
unperforated by a central aperture, as shewn detached in Figs. 5, where two
varieties of make are represented.
In stoves of large diameter I have found that it is advantageous to doubly gill
the lower rings of iron which are exposed to the greatest heat, and this arrange-
ment is shown in the plan view and front elevation, Figuros 2 and 3, but in stoves
of ordinary medium size this double gilling will not be necessary.
By this sectional construction of stove all the parts may be speedily and easily
removed for inspection or repair.
The external heating capacity of the stove is not affected by the use of the
central pipe, which pipe most advantageously reduces the quantity of fuel required
to charge the stove, and utilizes to the fullest extent the great heat developed in
the centre of the stove. By properly proportioning the belt of fuel in this
arrangement great economy is secured, and the total heating power of the apparatus
is increased by one-third.
I would remark that the coating or wash of gannister above referred to as being
preferably employed as an additional protection to the pipe B is not essential to
the success of my Invention, but may be advantageously used therewith.
Having now set forth the nature of my said Invention of "Improvements in
Stoves," and having explained in what manner the same may be carried into
practical effect, I wish it to be understood that I claim,-
First. Protecting from the destructive action of the fire the metal air tubes,
which pass through the fuel in pedestal and other stoves, by the application
thereto of a casing of plumbago or fireclay composed of loose sections, as above
described.
Secondly. The adaptation to pedestal stoves of the combined grating and dead
plate arranged with respect to the firo door, as and for the purpose above
described.
In witness whereof, I, the said William Barton, have hereunto set my hand
and seal, the Fourteenth day of December, in the year of our Lord One
thousand eight hundred and eighty one.
