PROVISIONAL SPECIFICATION.
Improvements in Stoves.
I ARTHUR WYNDHAM MARTIN, of Gorebrook House, Hyde Road, Gorton in
the County of Lancaster, Surgeon, do hereby declare the nature of this invention
to be as follows:-
My said invention relates to portable stoves. Inside the outer casing is a sheet
metal liner whose external diameter is somewhat less than that of the interior of
the casing so as to provide an air space for preventing overheating of the outer
casing. In some cases the outer casing may be perforated to allow of the passage
into the room of the air between the liner and the outer casing.
The fuel receptacle is inside and rests on an internal flange of the liner. An air
space is left between the liner and the fuel receptacle. The latter is less in
diameter than the interior of the liner which is provided with ribs or projections
for holding the fuel receptacle central. The fuel receptacle is perforated at the
bottom and sides.
The liner is covered by an internal lid in order to provide an air space under and
prevent overheating of the cover of the outer case. The said internal lid is hinged
to enable the fuel in the receptacle to be readily lighted.
In the lower part of the stove is a drawer for the ashes falling from the fuel
receptacle. The front of the drawer is provided with valves or air inlets having a
sliding cover plate for the purpose of regulating the inlet of air.
A separate air chamber is formed underneath the drawer in order that the base
of the stove may remain cool.
An exit for the gaseous products of combustion is provided at one side of the top
of the casing and liner.

COMPLETE SPECIFICATION.
Improvements in Stoves.
I ARTHUR WYNDHAM MARTIN of Gorebrook House, Hyde Road, Gorton, in
the County of Lancaster, Surgeon, 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 said invention relates to an improved construction of portable stoves.
In order that my said invention may be more clearly understood I will describe
the same with reference to the accompanying drawing in which Figure 1 represents
a sectional elevation of the entire stove and Figure 2 a front elevation of the
ash tray.
a is the external casing, b c are respectively the outer and inner walls of a liner
which I prefer to make hollow with the walls about a quarter of an inch apart so
as to leave an air space. d is a loose bucket shaped fuel receptacle having at the
bottom a perforated rim or feet d¹ resting on flanges projecting from the
inner wall of the liner. The fuel receptacle d which is perforated at the bottom
and sides is less than the internal diameter of the liner in order that the air may
circulate all round and enter the fuel receptacle at the sides as well as at the
bottom. Suitable ribs or projections are provided for keeping the fuel receptacle
Paine 71

page_text: central. The products of combustion pass off through the vent ƒ to a pipe leading
to the chimney.
e is a sliding ash tray or drawer the front of which is provided with air inlets
or valves e¹ covered by sliding cover plates e³ for regulating the admission of air.
Between the flat bottom c² of the liner and the base of the stove an air chamber g'
is provided. Perforations are made therein as shown in the drawing to admit air
to the bottom air chamber g'. The outer chamber g may also be perforated near
the bottom at g³ and also near the top at 92 in order that the warmed air may pass
into the room.
A constant circulation of air thus takes place between the liner and
the outer casing whereby the latter is kept comparatively cool and in consequence
of the air space between b and c overheating of the stove is to a great extent
prevented. Where a single liner is employed I prefer to dispense with the
perforations g² g³. The liner or when made double the inner wall thereof is loose
and can be readily replaced.
Immediately over the liner is an inner lid h one part of which h¹is hinged to
give access to the fuel receptacle.
The top cover i is hollow and may be also perforated at the top and sides. A
projecting rim under the cover i takes into a channel at the top of the outer
casing. The said channel is partly filled with sand so as to form a sand lute and
prevent the escape of the products of combustion from the interior of the stove into
the room.
The shape and proportions of the different parts of the stove may be considerably
varied without departing from the essential features of my said invention.
To use the stove the fuel receptacle d is nearly filled with fuel on the top of
which a few sticks of wood or an ordinary fire lighter is placed and on the latter a
small quantity of coal. The loose inner lid is then put on and the fire is lighted
through the hinged part of the inner lid which is then closed and the top cover i
is put on.
The fire is intended to burn downwards.
Owing to the air chamber g' the bottom of the stove is kept so cool that it may
with perfect safety be placed over a carpet or wooden floor when resting on the
feet k.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.-
1. A stove constructed substantially as hereinbefore described and shown in the
accompanying drawing.
2. In a stove the combination of the outer casing a the air space g the single or
double liner be and the fuel receptacle d having perforations at the bottom and
sides and so much less in diameter than the liner as that air can freely circulate
round the fuel receptacle substantially as and for the purpose set forth and shown.
3. In a stove the combination of a fuel receptacle perforated at the bottom and
sides with a surrounding air insulated casing whose internal diameter is sufficient to
allow of air circulating round the fuel receptacle substantially as and for the
purpose set forth.
4. In a stove of the kind described the air circulating chambers 9 and 9¹
substantially as and for the purpose set forth.
