Firm of Charles Jeakes and Company, of Great Russell Street,
Bloomsbury, in the County of Middlesex, Engineers, for the
Invention of "IMPROVEMENTS IN COOKING APPARATUS."
Sealed the 18th September 1868, and dated the 1st April 1868.
PROVISIONAL SPECIFICATION left by the said James Norris and
Thomas Quarm at the Office of the Commissioners of Patents, with
their Petition, on the 1st April 1868.
We, JAMES NORRIS and THOMAS QUARM, both of the Firm of
Charles Jeakes and Company, of Great Russell Street, Bloomsbury, in
the County of Middlesex, Engineers, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN COOKING APPARATUS," to be as
follows:-
This Invention relates to improvements in cooking apparatus of the
character described in the Specifications of the Letters Patent granted
to Robert Baker Jones, dated respectively February 23rd, 1856,

page_text: No. 407, and October 28th, 1805, NO. 2072; and our invention nas for
its object improved arrangements and combinations of parts whereby
the heat is more effectively utilized, greater facility being afforded for
varying the number of cooking operations carried on with additional
convenience for packing up the parts more compactly together for
removal from place to place.
According to our improvements a fire-box or chamber is constructed
in front of the apparatus in combination with a boiler or boilers arranged
on each side and extending to the back of the apparatus, a flue being
formed from the fire space' passing underneath the boiler or boilers to
a removeable smoke box arranged at the back, upon which a chimney
is mounted formed telescopically or in sections, which slide into each
other and pack into the smoke box, which can be detached and packed
up in the fire-place or chamber. The smoke box may be arranged as a
boiler, with a passage through it to the chimney. The frame of bars or
open front of the fire chamber is removeable, the separate fire basket
described in the Specifications before referred to being dispensed with.
The boiler fits and is supported upon a hollow base arranged as an
oven, with doors on each side the flue to the smoke box being formed
between the two parts, thus affording great facility for cleaning and
packing. The smoke box is formed with holes to receive saucepans or
other cooking vessels. Above the boiler a steamer of comparatively
large capacity (with divisions if desired) is mounted; the bottom of which
is arranged as a tray or receptacle for catching the condensed steam and
liquid from the articles cooked, a pipe or passage at one end conducting
it away into a suitable receiver; or the liquid may be allowed to flow
over the sides of the tray into the boiler below when used for making
soup. The steamer is by preference of taper form, and is furnished
with a sliding cover, which may be used as a blower to draw up the fire
when required. A folding Dutch oven of improved construction is
arranged in front of the apparatus with dripping pan, fat chamber,
draw-off passage, and sliding grids, which can be packed with saucepans
into the main steamer, which, when closed by its cover can be turned
over and be dropped into the boiler, so as to occupy but small space.
A separate boiler and steamer is arranged to hang upon the front bars of
the fire chamber, and is capable of being stowed away in the oven when
the apparatus is packed up for removal. An additional boiler and
steamer is arranged to pack into the larger steamer suitably constructed

page_text: for being placed over the front portion of the fire, and connected with
the side steam boilers.

performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said James Norris, on behalf
of myself and the said Thomas Quarm, do hereby declare the nature
of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
!

page_text: more effectively utilized, greater facility being afforded for varying the
number of cooking operations carried on with additional convenience
for packing up the parts more compactly together for removal from
place to place.
According to our improvements a fire-box or chamber is constructed
in front of the apparatus in combination with a boiler or boilers arranged
on each side, and extending to the back of the apparatus, a flue being
formed from the fire space passing underneath the boiler or boilers to
a removeable smoke box arranged at the back, upon which a chimney
is mounted, formed telescopically or in sections, which slide into each
other and pack into the smoke box, which can be detached and packed
up in the fire-place or chamber. The smoke box may be arranged as
a boiler with a passage through it to the chimney. The frame of bars
or open front of the fire chamber is removeable, the separate fire basket
described in the Specifications before referred to being dispensed with.
The boiler fits and is supported upon a hollow base arranged as an oven
with doors on each side, the flue to the smoke box being formed between
the two parts, thus affording great facility for cleaning and packing.
The smoke box is formed with holes to receive saucepans or other
cooking vessels. Above the boiler a steamer of comparatively large
capacity (with divisions if desired) is mounted, the bottom of which is
arranged as a tray or receptacle for catching the condensed steam and
liquid from the articles cooked, a pipe or passage at one end conducting
it away into a suitable receiver; or the liquid may be allowed to flow
over the sides of the tray into the boiler below when used for making
soup. The steamer is by preference of taper form, and is furnished
with a sliding cover, which may be used as a blower to draw up the fire
when required. A folding Dutch oven of improved construction is
arranged in front of the apparatus, with dripping pans, fat chamber,
draw-off passage, and sliding grids, which can be packed with the
saucepans into the main steamer, which, when closed by its cover, can
be turned over and be dropped into the boiler so as to occupy but small
space: A separate boiler and steamer is arranged to hang upon the

page_text: forms of portable cooking stoves constructed and arranged according
to our present improvements.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a front view; Figure 2, a side view; Figure 3, a
longitudinal vertical section; Figure 4, a transverse vertical section
through the line A, B, in Figure 5; and Figure 5, a plan of an improved
portable cooking apparatus constructed according to our present
improvements.
a is the fire-box, within which the fuel is placed, the fire-box being
covered by the removeable plate a¹. The sides and back of the fire-
box a are formed at the upper part by the boiler b, which if desired
may be divided into compartments, and the sides and back of the fire-
The front of the
box a are formed at the lower part by the oven c.
fire-box a is enclosed by the frame of grate bars a², which is so con-
structed that. it may be withdrawn from the guides a when it is
necessary to remove the fuel quickly from the fire-box. The oven c
and the whole apparatus is supported upon the legs c', which are hinged
so as to turn back for the convenience of carriage. The boiler fits
and is supported upon the hollow base or oven c, a space being left
between the boiler band the oven c. to form the fluc d, by which the
heated products of combustion pass under the boiler or boilers b and
over the oven c to the smoke box or flue chamber e arranged at the back
of the stove. The smoke box e is so constructed as to be removeable,
being withdrawn when necessary by means of the handle e' from guides
formed at the back of the stove, and the smoke box e is so formed that
after it is removed it will pack into the fire-box a; f is a chimney
formed in lengths, the first length being placed over a suitable aperture
in the smoke box e, and the other lengths one upon the end of the
other to form any suitable length of chimney. The various lengths of
the chimney fare conical in form, each succeeding length being smaller

page_text: than the one upon which it is placed, so that when the various lengths
are dismounted they may be placed one inside the other, and the whole
afterwards placed within the smoke box e; f¹ is a damper or valve for
regulating the draught, the damper f being placed at the junction
between two lengths of the chimney f can be removed for packing
up when they are separated. The oven c is provided with doors at c², c³,
and extends to the back of the apparatus, and the boiler b, which also
extends to the back of the apparatus, is provided with a tap at b¹.
Above the boiler or boilers b is arranged a steamer g, furnished with
a lid g'; the steamer g is of comparatively large capacity, and may
have divisions if required, and where the apparatus is of a longer form
several of such steamers g may be employed.
and fat chamber h², from
convenient means; there is
Figure 6 shows an, and Figure 7 a vertical longitudinal section
on a larger scale of the lower part of the steamer g, the bottom
of which is perforated, and a tray or receptacle gå is arranged under
the perforated bottom of the steamer g, which serves to catch the
condensed steam and liquid from the articles cooked in the steamer, a
pipe or passage g³ conducting it away into a suitable receiver, the effect
of this contrivance being that the water or other liquid in the boiler 6
does not become mixed with the liquid condensed in the steamer g;
or the liquid may be allowed to flow over the sides of the tray into
the boiler below when making soup. is a Dutch oven, which when
desired may be placed in front of the fire chamber a. The Dutch
oven is provided with a dripping pan
which the fat may be drawn off by any
also a door at the back of the oven for the convenience of the
attendant, and at ' are ledges or projections within the oven h, which
serve to support grids or trays. The oven h is supported and slides
upon the bars h³, so as to stand at any suitable distance from the fire;
the bars are removeable, being placed when required in guides h
formed under the stove. The sides and back of the Dutch oven are
hinged to the bottom, and the top is hinged to the back, so that the
sides, back, and top of the oven may be folded over the bottom in a
small compass to pack into the steamer g; i,, are saucepans or steamers
placed over the boiler b at cither side of the fire-box a; and j, j', are
saucepans placed over the smoke box e. When the Dutch oven his
not in use a separate boiler and steamer may be hung in front of the
frame of bars a'. When it is desired to pack up the above described

page_text: apparatus the last named boiler and steamer are placed in the oven
with the oven pans. The Dutch oven h with trays, poker, and sauce-
pans and covers are packed into the steamer, which is then closed by
a cover constructed to slide over the top and around the rim, so as to
be secure when the steamer g is turned over. This last named cover
being also so formed as to slide down the guide pieces a³ and act as a
blower when lighting the fire. The steamer g is by preference of taper
form, so that when filled with the articles and closed by the sliding
cover, as above described, it may be turned over and readily inserted
into the boiler b, the cover g¹ being afterwards placed over the bottom of
the steamer g; which is formed to receive it, the smoke box e enclosing
the chimney f, as above described, is then placed in the fire-box a, and
the apparatus is then ready packed for transport.
Figures 8 and 9 shew side views, Figure 10 a front view, Figure 11
a plan, and Figure 12 a longitudinal vertical section (taken through
the line C, D, Figure 12) of a portable cooking stove constructed
according to our present improvements, the parts corresponding with
these, previously described in reference to Figures 1 to 8, being marked
with similar letters of reference. In this stove the relative position of
the parts is similar to that previously described, but they are not so
constructed as to admit of being packed one within another. The fire-
box is furnished with two grates a, as, one above the other. The
fire-box is also furnished with doors at a, a, and as. It will be seen
on examining the Drawing that the cinders falling from the upper
grate a will be caught by the lower grate as and form a second fire,
by which the fuel will be economized, the ashes eventually falling into
the receptacle a. In this arrangement the boiler.b is divided into
three parts, the part arranged over and at the back and sides of the
fire being a closed steam boiler furnished with a safety valve, and from
this closed boiler a steam pipe 62 is conducted, with taps at 6' and ',
so as to supply steam to the steamers or cooking vessels k, k', supported
upon the hinged brackets. Over the other two compartments of the
boiler & steamers g are arranged, furnished with trays or receptacles g',
as before described. The oven c is also divided into two chambers, and
in addition to the flue d between the boilers and ovens there is another
flue d' under the ovens c, the flues & and d' being carried separately, as
shewn, up the smoke box e as far as the dampers e², e³, by means of
which the ovens or boilers may be more or less heated according to
the requirements of the case. The smoke box e is arranged as a boiler,

page_text: the passages or flues d, d', to the chimney being surrounded by a water
space, as shewn, from which hot water may be drawn from time to time
by means of a tap, the water being poured in through an aperture in the
upper part. The smoke box e is removeable, being so constructed as to
be capable of being lifted out of the end of the stove, as shewn in the
Drawing.
Having thus described the nature of our Invention, and the manner
in which we carry the same into effect, we would have it understood
that we do not confine ourselves to the precise details of construction
and arrangements herein shewn and described, which may be greatly
varied without departing from the nature of our Invention; but what
we claim is,―
Firstly. The general combination, arrangement, and relative position
of the parts of a portable cooking apparatus, both when in use and
when packed for transport, substantially as herein shewn and described
in reference to Figures 1 to 7 of the Drawings.
Secondly. We claim the general combination, arrangement, and
relative position of the parts of a portable cooking apparatus, sub-
stantially as herein shewn and described in reference to Figures 8
to 12 of the Drawings.
Thirdly. We claim the arrangement of the receptacle 9' and passage g³
for collecting and conveying away the condensed liquid from steamers
for cooking purposes, substantially as and for the purpose herein
shewn and described.
In witness whereof, I, the said James Norris, have hereunto set my
hand and seal, this Thirtieth day of September, One thousand
eight hundred and sixty-eight.
