An Improvement in Portable Cooking Stoves.
I, ALFRED SAVILL TOMKINS of Holmwood, Caterham in the County of Surrey,
Captain in the Victoria Rifles, do hereby declare the nature of this invention to be as
follows:-
My invention relates to the construction of portable cooking stoves specially adapted
for the use of military men or travellers, the stove being so arranged that it can be
used with safety in a tent or waggon as well as in the open air.
In the middle of the
lower part of the stove there is a fireplace occupying about one third of the width
and nearly the whole depth, and under the fire grate there is a pan to receive the
cinders and ashes, this pan having an air space below it and being removeable to be
emptied. The space on each side of the fire place and below the ash pit pan forms a
heating chamber for air which is admitted at the lower part of the chamber and issues
from the upper part by an aperture or by a pipe by which the warmed air can be
ted to any chamber or compartment requiring to be heated.
From the crown of the fire place there extends upwards a flue of rectangular
section, narrow in width but having considerable depth from front to back.
On each side of this flue is an oven. Over the top of the flue there is a
plate which deflects the hot products of combustion and makes then travel
horizontally under the plate and over the tops of the ovens, and finally find
their way, as directed by suitable baffles, at the back of the stove. On the plate, which,
as well as the top of the ovens, is thus heated, are placed boilers, four of which can be
accommodated on the plate. At the bottom of the rectangular flue I prefer to place a
fire grate so that fuel being fed into the flue by a sloping opening in front, the flue
itself can serve as the fire place when full heating is not required.

An Improvement in Portable Cooking Stoves.
I, ALFRED SAVILL TOMKINS, of Holmwood, Caterham, in the County of Surrey,
Captain in the Victoria Rifles, 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 invention relates to the construction of portable cooking stoves specially
adapted for the use of military men or travellers, the stove being so arranged that
it can be used with safety in a tent or waggon as well as in the open air.
In the middle of the lower part of the stove there is a fire place occupying about
one third of the width and nearly the whole depth, and under the fire grate there is
a pan to receive the cinders and ashes, this pan having an air space below it and
being removeable to be emptied.
From the crown of the fire place there extends upwards a flue of rectangular
section narrow in width but having considerable depth from from front to back. On
each side of this flue is an oven.
Over the top of the flue there is a plate which deflects the hot products of com-
bustion and makes them travel horizontally under the plate and over the tops of the
ovens, and finally find their way as directed by suitable baffles at the back of the stove.
On the plate, which as well as the top of the ovens is thus heated are placed boilers,
four of which can be accommodated on the plate. At the bottom of the rectangular
flue I prefer to place a fire grate so that fuel being fed into the flue by a sloping
opening in front the flue itself can serve as the fire place when full heating is not
required.
The stove is preferably made in separate parts so as to render same convenient for
transport on pack animals or otherwise.
Figs. 1 and 2 of the accompanying drawings are vertical sections on planes at right
angles to one another, and Fig. 3 is a sectional plan of a cooking apparatus or camp
stove according to my invention.
F is the fire place which can he supplied with fuel through the door O and down the
inclined shoot N the draught being regulated by the ashpit door S. The hot products of
combustion ascend the central flue space C from which two side spaces CC branch
each way and finally pass away by the chimney C.
On each side of the fire F is a space T which can be used as an oven or for drying
materials placed in it. The space on each side of the flue C is divided by horizontal
partitions so as to form four ovens F1 in which are placed cooking vessels or dishes B².
On the upper part of the stove are placed boilers K. At the back and sides of the

page_text: stove there is a separate water casing R which effectually protects from fire any
combustible material in the neighbourhood of the stove.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A portable cooking apparatus consisting of a fire place F, flues Cand ( chimney C³,
ovens F¹ and boilers K in combination with the water casing R substantially as
described.
