WC, JOHN ALEXANDER HANNA and THOMAS FOULKES SHILLINGTON, both of
Musgrave and Company, Limited, Ann Street Iron Works, Belfast, in the County of
Antrim, Ireland do hereby declare the nature of this invention to be as follows:-
Our invention relates to stoves of the kind or class described in the Specification of
former Letters Patent granted to us and dated April 14th A.D. 1883 No. 1906, and
chiefly to such as are provided with transparent panels in the sides or doors thereof.
In carrying our present invention into practice, we proceed as follows; that is to
say-We make the fire-bars vertical as described in our said former specification and,
by preference, solid instead of tubular. Instead, however, of making them of the
samme, or nearly the same height as the door in front of them, we make them either in
one or two parts and either hinged or stationary and so that they extend almost the
full height of the stove, merely leaving sufficient space at their lower ends to permit
the removal of ashes and the like. The front or the sides of the stove, or both the
front and the sides are formed with an overhanging canopy projecting over the bars
and so placed as to intercept any gases or smoke that may escape through the bars.
The upper part of the range of bars is made in the form of louvres or with
perforations sloping downwards towards the interior of the stove, so as not to allow
ashes or fuel to fall through them, but, at the same time, permit the free passage of
the air or gases.
To prevent the falling of ashes or dust from the stove at the inside of the front
door, we provide a flap or supplementary door hinged or pivotted in any suitable
manner at its lower edge. This flap remains in a vertical position usually, but can be
folded downwards to permit the removal of the ashes. The air for combustion is
admitted in front of this flap through suitable inlets provided with regulators; the
flap thus acts as a spreader to prevent the entering air striking any part of the fire too
keenly. The said flap is held in the vertical position by means of any suitable latch
or bolt.
The front door may be used or may be dispensed with as desired: it may be closed
o as to make a close-fire stoves, or it may be left open so as to make an open-fire stove,
ny smoke or gases escaping from the lower part of the fire-bars being intercepied

page_text: and carried off through the aforesaid canopy and louvres by the action of the draught
in the chimney.
The front door as described in our said former specification was fitted with
transparent panels of mica or glass; we sometimes use panels of thin china instead of
glass or mica. Or we make the door of close or solid metal work, or with perforations
which form various designs or devices to be illuminated by the fire in the stove.
If it is desired to cause a keener or more rapid combustion of the fuel, we provide
the top of the front door with a horizontal flange projecting inward. When the door
is shut, this flange touches the bars and thus prevents the passage of air through the
louvres and compels it to pass through the fire.
In some instances, we provide our stoves with suitable insulated or non-conducting
handles either firmly attached or hinged to such of the doors as require to be opened
and shut. These handles we usually make of earthenware, they may, however, be
made either wholly or partially of any other suitable non-conductor of heat, or, if made
of metal, may be disconnected or insulated, by means of a collar of nonconducting
material, from the part of the stove to which they are attached.

page_text: Improvements in Stoves.
We, JOHN ALEXANDER HANNA and THOMAS FOULKES SHILLINGTON, both of
Musgrave and Company, Limited, Ann Street Iron Works, Belfast, in the County
of Antrim, Ireland, 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 :—
Our invention relates to slow combustion stoves, that is to say, stoves in which a
large body of fuel will remain incandescent and burning at a slow rate. Our improved
stoves are chiefly designed for burning anthracite or coke, they are, however, suitable
for burning other kinds of fuel. Our said invention comprises various improvements
hereinafter set forth.
We construct our improved stove with an enc.osed space or chamber for the fuel
and preferably with a flue or flues through which the smoke and gases from the fire
will pass and give off their beat. The fire-chamber or fuel-chamber is surrounded
partly by fire-clay slabs and partly by fire-bars. In some instances, transparent, semi-
transparent or perforated panels are fitted in the front or sides, or in both the front
and the sides of the fire-chamber to allow the light of the fire to be seen as described
in the Specification of Letters Patent dated 14th April 1883, No. 1906. In other
instances, the said front and sides are made entirely of opaque material.
In the accompanying drawing.
Figure 1 is a vertical central section of one form of our improved stove.
Figure 2 is a horizontal section on the line a, c, Figure 1.
Figure 3 is a horizontal section showing another form of modification of our stove,
and
Figure 4 is a vertical central section, showing a further modification thereof.
a is the fire-chamber or fuel-chamber. b,b are vertical fire-bars which are by
preference solid; they may, however, be made tubular, if desired, so as to allow a
current of air to pass through them to keep them cool. These bars are made in one
or more parts and are either hinged or stationary, they extend almost the full height
of the stove, merely leaving sufficient space at their lower ends to permit the removal
of ashes and the like. The bars are shown in Figures 1 and 2 on the front only of
the fire-chamber. They may, however, be arranged at the side or at both the front
and the side as shown for example in Figure 3. Wherever the bars exist, an over-
hanging conopy c is provided, which projects over the hars and is so placed as to
intercept any gases or smoke that may escape through the bars.
The upper part d of the range of bars is made in the form of louvres, or with
perforations sloping downwards towards the interior of the stove, so as not to allow
shes or fuel to fall through them, but, at the same time, to permit the free passage of
the air or gases into the space above the fire.
To prevent the falling of ashes or dust from the stove at the inside of the front door,
ve provide a flap or supplementary door e hinged or pivoted in any suitable manner
t its lower edge e'; this flap remains in a vertical position usually, but can be folded
lownwards to permit the removal of the ashes when the front door f is opened. The

page_text: air for combustion is admitted in front of this flap through suitable inlets provided
with regulators as at g. The flap thus acts as a spreader to prevent the entering air
striking any part of the fire too keenly. The air passes upward between the said flap
and the front door. The said flap is held in the vertical position by means of any
suitable latch or bolt, such as that shown at 2 which is pivoted to the supplementary 5
door e and engages with a stud or projection e³.
The front door may be used or may be dispensed with as desired; it may be closed
so as to make a close-fire stove, or it may be left open so as to make an open-fire
stove, any smoke or gases escaping from the lower part of the fire-bars being inter-
cepted and carried off, when the front door is opened, through the aforesaid canopy and
louvres by the action of the draught in the chimney.
The front door is fitted with transparent panels h of thin china having any orna-
mental design either painted or embossed thereon, or with panels of close or solid metal
work, or with perforations which form various designs or devices to be illuminated by
the fire in the stove. Or, if desired, it may be provided with mica or glass panels.
If it is desired to cause a keener or more rapid combustion of the fuel, we provide
the top of the front door with a horizontal flange i projecting inward. When the
door is shut, this flange touches the bars and thus prevents the passage of air
upwards into the canopy and through the louvres and compels it to pass through
the fire.
In some instances, we provide our stoves with suitable insulating or non-conducting
handles as at A, either firmly attached or hinged to such of the doors as require to be
opened and shut. These handles we usually make of earthenware, they may, however,
be made either wholly or partially of any other suitable non-conductor of heat, or, if
made of metal, may be disconnected or insulated, by means of a collar of non-conducting
material, from the part of the stove to which they are attached.
In Figure 3, we have shown a simple form of our stove in which there are no
flues. A similar stove may be made square or of other suitable shape if desired.
Jn Figure 4 we have shown a stove made with a solid sloping bottom and with an
air-chamber and smoke-flues arranged at the back of the fuel-chamber. The front
and sides of this stove is provided with fire-bars, canopies and louvres as above
described.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is;
First. A slow combustion stove so constructed that it may be used either as a close
fire-stove or as an open-fire stove, substantially as set forth.
Second. A slow combustion stove wherein the fire-bars are vertical and extend
from the top nearly to the bottom of the fuel-chamber, substantially as set forth.
Third. The employment of a canopy and louvres at the top of the fire-bars, substantially
as, and for the purposes, set forth.
Fourth. The employment of a supplementary door or flap hinged or pivoted at it
lower edge, substantially as, and for the purpose, set forth.
Fifth. The provision of an inwardly projecting plate or flange at the top of the door
substantially as, and for the purpose, set forth.
Sixth. The employment of non-conducting handles substantially as described.
Seventh. The improved stove constructed substantially as described and as illustrate
in Figures 1 and 2, or in Figure 3, or in Figure 4 of the accompanying drawing.
