PROVISIONAL SPECIFICATION.
A New or Improved Portable Closed-in Stove or Outer Casing
or Wind-guard Combined with Stove for Picnicing or other
Purposes.
We, WALTER DARBY, ION DARBY, and JOHN HENRY PUNCHARD all of
249 Pentonville Road, King's Cross, London, N.W. Manufacturers, do hereby
declare the nature of this invention to be as follows:-
This invention relates to a new or improved portable closed-in stove or stove
combined with outer casing or wind-guard for picnicing or other purposes.
Any suitable form of stove and any suitable burner adapted to be arranged and
mounted according to our present invention may be used but our present invention
may advantageously he carried out with an oil or spirit stove of the character
described in Darby's Patent No. 6015 of 1895 and we will now therefore proceed
to describe our present invention as carried out in conjunction with such stove.
The stove is surrounded on all sides by an outer case or wall of any suitable
shape advantageously a rectangular tin or sheet metal box which is higher than
the stove so as to extend above the top of the latter and is closed at the top by a
hinged or removable lid or cover which latter may be provided with means to
attach same to the outer casing or cover and have a handle provided on said lid by
which to carry the whole apparatus or instead thereof any separate or other
suitable handle or means may be provided for carrying the apparatus for instance
loops or means may be provided on opposite sides of the box and a leather or other
suitable strap or straps secured to same and passing over the lid or cover thereby
not only keeping the latter in place but also serving as means by which to carry
the stove such strap being entirely removable when the stove is in use so as to
prevent injury thereto from the heat.
The stove is mounted and held rigidly in position within the casing by a
horizontal plate or division advantageously at or about the top of the burner so
that the casing is thus divided horizontally into two compartments in the lower of
which the burner is arranged to slide in and out in any suitable manner an aperture
or apertures of suitable size being provided in said horizontal division for the
flame or flames to pass through from the burner to that part of the stove above
the horizontal division.
In this latter (which may advantageously be of circular form as shown in
Darby's said Patent No. 6015 of 1895) a circular kettle having a central aperture
right through same vertically as shown in said Patent No. 6015 of 1895 may be
used so that while the water in said kettle is being heated cooking operation may
be carried on in another utensil supported over the top of said kettle as in the
aforesaid patent.
Or a grid or any other suitable support or supports may be provided for any
other utensil or utensils for use within or over the aforesaid stove.
The various utensils for use with this stove advantageously being arranged with
hinged or foldable handles so as to pack one within the other or closely together
within or around said stove and also the annulus or space between the stove and
the casing thereof may be further utilized by having fitted therein bottles or othér

page_text: vessel or vessels adapted respectively to contain oil or spirit for the burner or
water etc. as desired.
The aforesaid lower compartment in which the burner is contained as aforesaid
has a false bottom thereto or a horizontal plate or division upon which the burner
is supported so that a chamber is thus formed below same into which latter air to
support combustion can enter through perforations provided through the side of
the casing at or near the bottom thereof and thence such air supply can rise
vertically through holes or perforations in the said false bottom or horizontal
division supporting the burner or between the burner and the aforesaid apertures
in the side of the casing the object of having this series of holes or perforations in
the vertical sides of the casing as well as in the horizontal division being to baffle
or regulate the air inlet so that sudden gusts of wind are broken up and prevented
from blowing out the flame.
If desired coarse gauze or other reticulated material or other devices may be
interposed between the burner and the exterior of the casing to further regulate
and protect the admission of air to the burner to support combustion.
A hinged or removable door with suitable catch or fastening is advantageously
provided in the lower part of the casing to gain admission to the burner so that
the latter can be easily withdrawn for filling cleaning etc.
We also find it very advantageous to form an aperture or apertures in the
aforesaid horizontal plate or division between the burner compartment and the
uppermost compartment and at a point in said division between the stove and
the outer casing so as thus to afford means for heated air forming around the burner
escaping from the burner compartment to the upper compartment and thence to
the exterior of the apparatus whereby we have found the burner and burner
compartment are kept very cool.
By extending the sides of the casing upwards above the top of the stove as
above described we thereby prevent the flame from being blown out from above.
.. If desired any suitable bottle or bottles or vessels or utensils may be arranged
to be packed in the burner compartment alongside the burner.
A window. or other suitable aperture or apertures protected or covered by
suitable transparent or reticulated material may be provided in the case as also in
the stove so that the flame can be seen therethrough for regulating etc.

A New or Improved Portable Closed-in Stove or Outer Casing
or Wind-guard Combined with Stove for Picnicing or other
Purposes.
We, WALTER DARBY, ION DARBY and JOHN HENRY PUNCHARD all of
249 Pentonville Road, King's Cross, London, N.W. Manufacturers, do hereby
declare the nature of this invention and in what manner the saine is to be
performed to be particularly described and ascertained in and by the following
statement:-
This invention relates to a new or improved portable closed-in stove or stove
combined with outer casing or wind-guard for picnicing or other purposes.
Any suitable form of stove and any suitable burner adapted to be arranged and
mounted according to our present invention may be used but our present invention

page_text: may advantageously be carried out with an oil or spirit stove of the character,
described in Darby's Patent No. 6015 of 1895 and we will now therefore proceed
to describe our present invention as carried out in conjunction with such stove such
arrangement being illustrated in Sheet 1 of the accompanying drawings-in.
which:-
Fig. 1 is an elevation partly in section (the top part of one side of the casing
being removed and also part of the upper part of the stove broken out),
showing the interior arrangement and construction of this apparatus.
Fig. 2 shows same closed for cooking.
Fig. 3 shows same packed for travelling.
Similar letters of reference indicate corresponding parts throughout.
The stove a is surrounded on all sides by an outer case or wall of any suitable-
shape advantageously a rectangular tin or sheet metal box & which is higher than
the stove a so as to extend above the top of the latter and is closed at the top by a
hinged or removable lid or cover c which latter may be provided with means to:
attach same to the outer easing b and may have a handle (not shown) provided on.
said lid c by which to carry the whole apparatus or instead thereof any separate or
other suitable handle or means may be provided for carrying the apparatus for
instance loops or other suitable means may be provided on opposite sides of the
box 6 and a leather or other suitable strap d or straps secured to same and passing
over the lid or cover e thereby not only keeping the latter in place but also serving
as means by which to carry the stove-such strap d being entirely removable when.
the stove a is in use so as to prevent injury thereto from the heat...
The stove a is mounted and held rigidly in position within the casing by a
horizontal plate or division e advantageously at or about the top of the burner f so
that the casing b is thus divided horizontally into two compartments y and z in the
lower y of which the burner f is arranged to slide in and out in any suitable manner
an aperture or apertures of any suitable size being provided in said horizontal
division e for the flame or flames to pass through from the burner to that part of
the stove a above the horizontal division e.
In this stove a (which may advantageously be of circular form as shown in
Darby's said Patent No. 6015 of 1895) a circular kettle g having a central
aperture right through same vertically as shown in said Patent No. 6015 of 1895,
may be used so that while the water in said kettle is being heated cooking
operation may be carried on in another utensil supported over the top of said!"
kettle as in the aforesaid patent for instance a pot h with foldable handle may be.
provided to pack below said kettle 9 and a frying pan i which is packed away by
inverting same over the top of the kettle g see Fig. 1.
Or a gridj or any other suitable support or supports may be provided for any
other utensil or utensils for use within or over the aforesaid stove a.
The various utensils for use with this stove advantageously being arranged with:
hinged or foldable handles so as to pack one within the other or closely together-
within or around said stove and also in the annulus or space between the stove a
and the casing & thereof may be further utilized by baving fitted therein bottles or
other vessel or vessels adapted respectively to contain oil or spirit for the burner
or water etc. as desired.
The aforesaid lower compartment y in which the burner is contained as.
aforesaid has a false bottom thereto or a horizontal plate or division m upon which
the burner / is supported so that a chamber is thus formed below same into which
latter air to support combustion can enter through perforations n provided through.
the side of. the casing at or near the bottom thereof and thence such air supply
can rise vertically through holes or perforations o in the said false bottom or
horizontal division m supporting the burner for between the burner and the
aforesaid apertares in the side-of the casing the object of having this series of
holes or perforations n in the vertical sides of the casing b as well as the holes o in.
the horizontal division m being to baffle or regulate the air inlet so that sudden.
gusts of wind are broken up and prevented from blowing out the flame.
:

page_text: If desired coarse gauze or other reticulated material or other devices may be
interposed between the burner and the exterior of the casing to further regulate
and protect the admission of air to the burner to support combustion.
A hinged or removable door p with suitable catch or fastening such as p' is
advantageously provided in the lower part of the casing to gain adinission to the
burner so that the latter can be easily withdrawn for filling cleaning etc.
We also find it very advantageous to form an aperture or apertures (not shown)
in the aforesaid horizontal plate or division e between the burner compartment y
and the uppermost compartment z and at a point in said division between the stove
and the outer casing so as thus to afford means for heated air forming around the
burner escaping from the burner compartment to the upper compartment and thence
to the exterior of the apparatus whereby we have found the burner and burner
compartment y are kept very cool.
By extending the sides of the casing upwards above the top of the stove a as
above described we thereby prevent the flame from being blown out from above..
If desired any suitable bottle or bottles or vessels or utensils (not shown) may
be arranged to be packed in the burner compartment y alongside the burner.
A window or other suitable aperture or apertures protected or covered by
suitable transparent or reticulated material a may be provided in the case as also
in the stove so that the flame can be seen therethrough for regulating etc.
Referring now to Sheet 2 of the annexed drawings:-
Fig. 4 is a front elevation partly in vertical section showing on a larger scale a
modification riz.: a much smaller stove (heated by spirit lamp) and casing or
wind-guard therefor.
Fig. 5 shows same in perspective packed for travelling.
Parts corresponding with those shown in, Sheet 1 are marked with similar letters
of reference.
s is a spirit lamp in the lower compartment. y below the division plate e-air
being admitted through apertures n in the casing b and baffled by vertical baffle
plates having apertures u therein through which the air supply passes to the
burner s.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. Providing a portable stove of the character described with a wind-guard or
outer casing combined and arranged to act substantially in the manner and for the
purposes herein before described.
2. An outer casing or wind-guard combined with a portable stove and arranged
to act substantially as hereinbefore described with reference to the drawings
hereunto annexed.
