IMPROVEMENTS IN PORTABLE COOKING APPARATUS OR FIELD KITCHENS
Year: 1884

page_text: I, JOHN CORDY BAXTER, Captain in the Royal Engineers, care of Ernest de
Pass, Office for Patents, 68, Fleet Street, London, do hereby declare the nature of
said invention for IMPROVEMENTS IN PORTABLE COOKING APPARATUS OR FIELD
KITCHENS, to be as follows:-
My Invention relates to improve on my cooking apparatus for which I obtained
Her Majesty's Letters Patent, No 4877, dated 13th October 1883.
In such specification I described my apparatus as consisting of a number of
superimposed and interchangeable vessels each of which was provided with a
central space or passage forming a combustion chamber and flue, and these vessels
were described and shewn as being all of the same size.
Now, my present improvements consist in constructing the apparatus in such a
manner that the annular vessels forming the apparatus may be nested or packed
one into the other so as to economize space, and to render the same readily
transportable. For this purpose, I construct each one of these vessels of smaller
size than the others, or in other words of less diameter than the others, and the
central spaces or passages of larger diameter than the others, in order that a
battery of these vessels may fit or nest one into the other, and may all be contained
in the largest of the said vessels.
When the apparatus is nested or packed the central space existing in the largest
vessel may be utilized for the reception of a pocket-filter, or other suitable article,
and the smallest and innermost vessel may receive canisters. A large frying pan
may be arranged to fit outside the largest of the vessels.
Any of the vessels may be fitted with a tap, to screw in, to draw off water, tea,
Boup, etc.
The iron stand or trivet which is placed on the top of the annular vessels, as
described in my previous Specification, is now partially surrounded with a thin
metal screen to prevent the wind from blowing the flame away from the kettle or
pot which surmounts the whole battery.
I also propose now to form the lids of each of the vessels with a hole or holes.
These holes may be protected by a hinged or pivotted cover in order that the food
may be inspected and stirred.

page_text: The walls of any of the central passages may be made double, for the reception
of sand or earth, so as to protect the outer wall of the passage or flue and to
produce a uniform heat in the vessel, so as to enable the vessels to be used for
baking purposes.
A leather strap passing round the "nest" of vessels, and the ordinary kettle or
pot, which is placed on the top, secures the whole in place.
I, JOHN CORDY BAXTER, Captain in the Royal Engineers, care of Ernest de
Pass, Office for Patents, 68, Fleet Street, London, do hereby declare the nature
of said invention for IMPROVEMENTS IN PORTABLE COOKING APPARATUS OR FIELD
KITCHENS, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, reference being.
had to the accompanying drawings, and to the letters and figures marked thereon,
that is to say:-
My Invention relates to improvements on my cooking apparatus for which I
obtained Her Majesty's Letters Patent, N° 4877, dated 13th October 1883.
In such specification I described my apparatus as consisting of. a number of
superimposed and interchangeable vessels, of any appropriate or suitable shape,.
each of which was provided with a central space or passage forming a combustion
chamber and flue, and these vessels were described and shewn as being all of the
same size.
Now my present improvements consist in constructing the apparatus in such
a manner that the annular vessels forming the same may be nested or packed
one into the other, so as to economize space, and to render the same readily
transportable.
And in order that my improvements may be readily understood I proceed to
describe the same with reference to the accompanying drawings.
Fig. 1, is a view partly in elevation and partly in section, of my improved cooking
apparatus, in its built up form, as ready for use.
Fig. 2, is a plan of the lowermost vessel.
Fig. 3, shews the apparatus in elevation. in its nested or packed form..
Fig. 4, is a vertical section of the same.
Fig. 5, is a horizontal section also of the same, taken on the line x, x, of fig. 4. .
The arrows in fig. 1 shew the entry and passage of air into and through the
apparatus,

page_text: For the purposes of my Invention I now construct each one of these vessels A,
of smaller size than the others, or in other words, of less diameter than the others,
and the central spaces or passages a, of larger diameter than the others, in order
that a battery of these vessels may fit or nest one into the other, and may all be
contained in the largest of the said vessels, as clearly shewn in fig. 4.
Or in some instances, as shewn in fig. 6, I make the vessels A, larger in diameter
at the top than at the bottom, and the central spaces or passages a, larger at the
bottom than at the top, and by this means the vessels fit or nest inside each other,
to a great extent, as clearly shewn in fig. 7. In this arrangement the lids b, are
piled one upon the top of the other on the nested vessels. Owing also to the form
of the vessels in this arrangement steps or ledges are formed on the outside and on
the inside of the apparatus when built up. These steps or ledges on the inner side
of the central passage forming the flue, deflect the flame from side to side, and at
the same time prevent the fuel falling down too quickly.
F
When the apparatus is nested or packed the central space existing in the largest
vessel may be utilized for the reception of a pocket filter B, or a canister, or other
requisite article, and the smallest and innermost vessel may receive canisters C.
A large frying pan D, may be arranged to fit outside the largest of the vessels, as
Been in figs. 3 and 4.
Any of the vessels A, may be fitted with a screw tap f, to draw off water, tea,
soup, etc.; and they may be covered with wood or other non-conducting material
or composition to prevent loss of heat.
The iron stand or trivet E which I have described in my former specification, as
being, in some cases placed on the top of the annular vessels A, is now partially
surrounded by a thin metal guard or screen e, as shewn in fig. 8, to prevent the
wind blowing the flame away from the kettle or pot P, which surmounts the whole
battery.
I also construct the lids b, of each of the vessels, with a hole, or holes d, d, in
order that the food may be inspected and stirred. These holes may be protected
by a hinged or pivotted cover.
In order to enable the vessels to be used for baking purposes, the walls of any or
all of the central passages may be made double, as shewn in figs. 9 and 10, to form
a chamber g, and into this chamber I introduce sand or earth, so as to protect the
outer wall of the central passage or flue a from the flame, and to produce a uniform
heat in the vessels.
Z, is the grate or grid, which may be circular or square, and on which the fuel is
placed.
The nest of annular vessels may be packed inside a metal case to protect the
same, and this metal case can also be used as a water pot, or, if placed on the top of
the apparatus, as an oven for baking purposes.
The lid of this metal case may, in some instances, be provided with a hole into
which the grate may be fixed, and another hole contrived in the side of the case
permits of the bars being cleaned and the ashes removed. When the apparatus is
to be set up, the annular vessels are built up on the lid of this metal case a little saud
being put in the bottom of the case. This arrangement is specially applicable for
use in boats.
The apparatus may also be used with an oil or other lamp, or with a gas
burner, placed inside, at bottom, or with liquid fuel placed in a pan or basin seb
underneath;
A leather strap G, passing round the "nest" of vessels, and the ordinary kettle
or pot on top, secures the whole in place.
Having now particularly described and ascertained the nature of the said
invention, and in what, manner the same is to be performed, I declare that what
I claim is
1. Constructing the annular cooking vessels, of whatever shape they may be, in
such a manner that their external dimensions decrease, while their central spaces

page_text: .
or passages increase, substantially as described and as shewn in figs, 1 3, 4 and 5 of
the drawings, in order that such vessels may nest or pack one into the other for
the purposes of economizing space and rendering the same readily transportable.
;
2. Constructing the lids or covers of the annular cooking vessels with holes,
provided or not with covers, as and for the purposes set forth.
3. Constructing the iron stand or trivet with a wind-guard or screen, as shewn
and described, and for the purpose set forth.
4. Constructing the annular cooking vessels all of the same size, but with
inclined sides and with central spaces or passages of truncated conical form as
described and shewn with reference to figs. 6 and 7 of the drawings, so that when
the lids are off the vessels nest or fit inside each other to a great extent.
5. Constructing the walls forming the central space or passage double, as shewn
in figs. 9 and 10, for the purpose of forming a chamber for the reception of sand or
earth, in order to enable the said vessels to serve for baking purposes.
