PROVISIONAL SPECIFICATION.
Improvements in or in connection with Oil or Gas Stoves for
Cooking and Heating Purposes, and Utensil for Use therewith.
We, WALTER DARBY and ION DARBY of The Weston Works, Weston Street,
King's Cross, London, Manufacturers, do hereby declare the nature of this invention
to be as follows:-
:-
This invention relates to oil or gas stoves for cooking or heating purposes and
more especially to what we may call domestic oil stoves and to a kettle or utensil
(for boiling or heating water or heating or cooking other liquids or materials or
for other purpose) for use in conjunction with such stove and our present invention
has for its object to provide a compact and quick acting cooking or heating stove
which will fry boil grill or otherwise cook any article or material while at the same
time boil water or other liquid in the aforesaid special utensil, and having many
advantages in use and which we propose making known under the name or term of
Darby's Breakfast Stove."

a
Our present invention is as follows:-
We use any suitable oil or gas burner or burners for instance in the case of gas
"Bunsen "burner of suitable size or in the case of oil any flat wick or other
hydro-carbon burner suitable for the purpose such as the well-known flat wick
burners now commonly used in oil-cooking-stoves generally-the oil reservoir being
advantageously of such a character as to afford a wide base or support for the stove
with its utensil or utensils on same.
Over the burner is mounted (either hinged or detachably connected or otherwise
as desired) a case or vessel formed of an enclosing wall of sheet iron or other
suitable material open at the top but closed at the bottom except where same fits
over or onto the hood of the burner or this enclosing wall may be continued down
any suitable
to the oil reservoir (to which same may be attached or detached in
manner) in which event such lower part of this case would be perforated or
provided with openings in any suitable manner to permit admission of air to the
burner.
This case may be of any desired shape but advantageously cylindrical or oval or
parallel sides with rounded ends.
At or near the top of this enclosing wall we form an annular shoulder or it may
be lugs or projections or other suitable means to provide a seat or seating or
support for the aforesaid utensil or the latter may have simply a projecting ledge
all round or projections at intervals around the top edge of same (or near thereto)
which simply rest on the top edge of said case and thus this utensil is held in
position and the latter being of corresponding shape to the case fits closely within
said enclosing wall after the manner of a piston or plunger in a cylinder.
Or this utensil may be of other shape or form as hereinafter explained.
This special utensil is essentially a kettle for boiling water but may be used for
any other desired purpose and when made to closely fit within the case (like a
piston) as aforesaid same prevents escape of heat or products of combustion
between it and the enclosing wall and has a central or other opening or openings
through same (advantageously conical in form) through which the heat and products
of combustion ascend.
The handle of this utensil may advantageously be detachable or hinged so as to
fold out of the way.

page_text: On the top of this utensil we arrange and mount (either immovably or pivotally
or removably) three or other suitable number of rests or supports upon which a
frying pan pot or other uteusil can be placed the whole of the heat coming from
the burner being thus directed against the bottom of such frying pan etc. and then
is free to escape laterally through the open space left between the top of the special
utensil and the bottom of the frying pan etc. standing on said supports which latter
are of a sufficient height for this purpose.
Or these supports or rests may be fixed or pivotally mounted to the aforesaid
case instead of to the said special utensil in which case the latter can be removed
when not required in use.
If the stove is required for use without the special utensil (with the aforesaid
rests or supports on same) same can be removed and a grid or grill or other
temporary support placed in the case upon which a pot etc. can be stood or other
cooking operation performed.
Instead of the aforesaid utensil closely fitting the case such utensil may be made
like an ordinary pot or kettle of a corresponding shape but much less in size than
the case and same is suspended or supported centrally within the enclosing wall of
said case in any suitable manner thus permitting the heat to escape around the
sides thereof, rests or supports being provided as before on which a frying
pan etc. can be used for cooking etc. simultaneously with boiling the water in such
utensil.

Improvements in or in connection with Oil or Gas Stoves for
Cooking and Heating Purposes, and Utensil for Use therewith.
We, WALTER DARBY and ION DARBY of The Weston Works, Weston Street,
King's Cross, London, Manufacturers, 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 :—
This invention relates to oil or gas stoves for cooking or heating purposes and
more especially to what we may call domestic oil stoves and to a kettle or utensil
(for boiling or heating water or heating or cooking other liquids or materials or for
other purpose) for use in conjunction with such stove and our present invention has
for its object to provide a compact and quick-acting cooking or heating stove
which will fry boil grill or otherwise cook any article or material while at the same
time boil water or other liquid in the aforesaid special utensil and having many
advantages in use and which we propose making known under the name or term of
* Darby's Breakfast Stove."
Our present invention is as follows ;-
We use any suitable oil or gas burner or burners for instance in the case of gas
a "Bunsen "
burner of suitable size or in the case of oil any flat wick or other
hydro-carbon burner suitable for the purpose such as the well known flat wick
burners now commonly used in oil-cooking-stoves generally-the oil reservoir being
advantageously of such a character as to afford a wide base or support for the
stove with its utensil or utensils.
For the sake of example we will describe an oil stove with reference to the
drawings hereunto annexed.
Fig. 1 is a side elevation-partly in section-of an oil stove and utensil therein
according to our present invention.

page_text: Fig. 18 a plan of same.
Fig. 3 is an edge view, and
Fig. 4 is a plan of a loose trivet or device for use as hereinafter described.
Over the burner a is mounted (either hinged or detachably connected as shown
or otherwise as desired) a case or vessel formed of an enclosing wall-of sheet.
iron or tin-plate or other suitable material-open at the top.
The bottom of this casing b fits over or onto the hood c of the burner or this
enclosing wall b may be continued down to the oil reservoir d (to which same may
be attached in any suitable manner) in which latter event such lower part (not
shown) of this case would be perforated or provided with openings in any suitable
manner to permit admission of air to the burner.
This case may be of any desired shape but advantageously of cylindrical form
as shown, or oval or having parallel sides with rounded ends.
At or near the top of this enclosing wall & we form arrange or mount a rim 6¹ or
it may be lugs or projections 62 or both b¹ and 2 as shown or other suitable means
may be used to provide a seat or seating or support for the utensil A hereinafter
described or the latter may have simply a projecting ledge A¹ all round or
projections at intervals around the top edge of same (or near thereto) which
simply rest on the top edge or rim of said case baud thus this utensil A is held
in position and the latter being of corresponding shape to the case fits closely
within said enclosing wall b after the manner of a piston or plunger in a
cylinder.
Or this utensil may if desired be of other shape or form to correspond with the
case b.
This special utensil A is essentially a kettle for boiling water but may be used
for any other desired pupose and being made to closely fit within the case (like a
piston) as shown same prevents escape of heat or products of combustion between
it and the enclosing wall & and has a central vertical opening Ax (or other opening
or openings either conical or otherwise through same) through which the heat
and products of combustion ascend.
The handle B of this utensil A may advantageously be detachable or may be
hinged so as to turn down out of the way as shown in Fig. 2.
C
On the top of this utensil A we arrange and mount (either immovably or
pivotally or removably) four or other suitable number of rests or supports (in
the case illustrated these are fixed) projecting above the top of the kettle A-
upon which a frying pan pot or other utensil can be placed the whole of the heat
coming from the burner up the passage A* through the kettle A being thus
directed against the bottom of such frying pan etc. (not shown) and then is free to
escape laterally through the open space left between the top of the special utensil A
and the bottom of the frying pan etc. standing on said supports C which latter are
of a sufficient height for this purpose.
If the stove is required for use without the special utensil A (with the aforesaid
rests or supports C thereon) same can be removed and a grid or grill or other
temporary support such as illustrated in Figs. 3 and 4 placed in the case upon
which a pot etc. can be stood or other cooking operation performed-the radial
arms D¹ of this device D being forked as shown to fit over the rests 62 to thus hold
said device in position while in use.
In the case illustrated the burner hood c is attached to the bottom of the case b
and is detachably connected to the burner by projections c¹ on said hood e passing
under lugs a' on the burner a a spring catch e on the opposite side engaging the
projection on the hood c to thus lock the parts together or release saine when
desired to gain access to the burner or wick thereof for lighting, cleaning,
filling, etc.
dare handles fixed to the base d by which to carry said stove.
bis window or aperture (covered with mica or other suitable transparent
material) through which to see the flame to regulate same.
Tant of bait A

page_text: F is filling orifice therefor.
As a modification-if desired-the kettle A may be made to fit in the case b
closely like a plunger as before described but inserted deeper therein i.e. inserted
so far or in such manner that the top of said kettle will be below the level of the rests
or supports on the top edge of the casing b whereby a pot or frying-pan can then
be placed or supported on said rests 62 while the kettle is in the casing (instead of
on the rests C on said kettle-which rests C on said kettle can in such arrangement
be dispensed with) and thus cooking operation carried on by means of the heat
coming through the passage A* in said kettle A simultaneously with heating the
water in said kettle as before-but this arrangement would cause the heating of
the handle of said kettle and we consider the arrangement shown in the drawings
more advantageous.
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. The combination with a burner forming the base or stand for the stove of a
case or enclosing wall mounted just over said burner, rests or supports for a cooking
utensil on the top of said case, a kettle adapted to fit closely as a plunger within
said case, a flange on said kettle to support same on or to the said top edge of said
case and a vertical passage or passages through said kettle substantially in the
manner and for the purposes herein before described.
2. The combination with an oil reservoir such as d forming the base or stand
for the stove of a case or enclosing wall such asb mounted just over the hood c of
the burner, rests or supports such as 2 on the outer edge of the rim on the top
of said case, a kettle such as A adapted to fit closely within said case b, a flange A¹
on said kettle to support same on the said rim b¹, a vertical passage such as A*
through said kettle, and rests or supports such as C on the top of said kettle A
substantially in the manner and for the purposes hereinbefore described and
illustrated in the drawings hereunto annexed.
3. The combination with a kettle having a vertical passage or passages there-
through of rests or supports such as C on the top thereof substantially in the
manner and for the purposes herein before set forth.
4. The improved cooking stove and utensil for use in conjunction therewith
arranged constructed combined and acting substantially in the manner and for
the purposes hereinbefore described and illustrated in the drawings hereunto
annexed.
