Improvements in Means or Apparatus for Warming or Cooking Food
and in Fuel to be used therewith.
I, HARRY JONES THADDEUS, of The Devonshire Club, St. James's Street in the
County of London, Artist, do hereby declare the nature of this invention to be as
follows:-
The object of the present invention is to construct a cheap, simple and convenient
warming or cooking apparatus for the use of soldiers, travellers, artisans and others
and to provide a suitable fuel to be used therewith.
In carrying my invention into effect for use in the army I construct of tinplate
a case or cover for the regulation canteens carried by the soldiers. This case or
cover is made in two parts the one fitting within the other and is provided with loops
in the same positions as upon the canteen by which it may be carried with the
straps usually employed for this purpose.
The lower half of this case is perforated at the bottom and around the lower
part of the sides and is fitted in the inside with two hinged rods or wires which are
parallel to the bottom and are curved to fit and lie against the sides of the case
when it is not in use and which are turned across the case and act as a support for
the canteen or cooking utensil when required.
The upper part of the case or cover is formed at the lower edge thereof with a
slot at each end through which when the apparatus is in use for cooking, the
handle of the cooking utensil passes when the upper part of the case or cover is
placed over the lower part thereof.
When the apparatus is in use for frying it is placed upon the tray which fits
into the top of the canteen, and when it is in use for boiling it is placed upon the
frying pan.
The fuel which is used with this apparatus is made into flat circular cakes
having a hole through the centre and projections on the surface, the composition of
which is as follows:-
4 ozs.
44 grs.
127 grs.
Charcoal,
Potassium Chlorate,
Gum acac No. 3,
1% or more
2 ozs.
Tow,
Water.
An
These cakes may be ignited by an ordinary match or they may be provided with
a patch of igniting material similar to that used on safety or other inatches.
annular cake of desiccated soup or other food material may be packed with a cake
of fuel and a cylinder of chocolate or tea or coffee essence may be placed through
the centre of these cakes so that no space is wasted.
The apparatus is used in the following manner;-
A cake of fuel is ignited and placed in the bottom of the case which is standing
upon the tray or frying pan as aforesaid, the cooking utensil is placed on the curved

page_text: rods and the top of the case is put into position on the lower portion to retain the
heat.

Improvements in Means or Apparatus for Warming or Cooking Food
and in Fuel to be usod therewith.
I, HARRY JONES THADDEUS, of The Devonshire Club, St. James's Street, London,
England, Artist, 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;-
The object of the present invention is to construct a cheap and simple warming
or cooking apparatus for the use of soldiers, travellers, and others and to provide a
suitable fuel to be used therewith.
In carrying my invention into effect I make use of a canteen consisting of a
container for water of flat form on one side and rounded on the other side, said
container being fitted with a shallow tray which is used as a plate and which
rests on the top of the water container, the whole being covered with another
tray provided with a folding handle and which may be used as a frying pan.
This canteen is of well known construction and separately considered it forms no
part of my present invention.
My invention is illustrated in the accompanying drawings in which Fig. 1.
shows a warming or cooking apparatus in section and Fig. 2. is a plan view of the
same with the top cover removed.
Fig. 3. is an end elevation of the apparatus as in use for boiling and Fig. 4. is
a plan of the same.
Fig. 5. is a vertical cross section showing the apparatus as used for boiling and
Fig. 6. is a horizontal section on the line 6. 6. of Fig. 5.
Fig. 7. is a plan of one of the cakes of fuel.
Fig. 1. shows the whole apparatus packed up for transport. It consists of a
case or cover made in two parts a and b forming a stove, the one part a fitting
over the other 6 and completely enclosing the canteen. The upper cover a is
provided with loops a by which it is carried by means of straps; it is formed
with two slots a through which the handle d' of the cooking utensil passes when in
use, as shown in Figures 3, 4, and 5.
The lower part of this case or cover b is perforated at the bottom and around
the lower part of its sides as shown in Figures 1, 3, 5 and 6, and it is fitted in
the inside with two hinged rods b¹ which are parallel to the bottom. These
rods b¹ lie against the sides of the case when not in use as shown in Fig. 2 and they
are turned across the case and act as a support for the cooking utensils when
required as shown in Figures 3, 4, 5, and 6.
În Figures 3, 4 and 5 I have shown the apparatus in use for boiling. On the
bottom of the lower case 6 I place a cake of fuel e and ignite the same I then stand!
the cooking utensil d upon the rods 6 and I place the upper case a over the lower
rase b with the handle d¹ projecting through the slots a2 and resting on the top of
the lower case b. The handle d' thus acts as a support for the upper case a.
The whole apparatus is then placed upon the tray as shown in Figures 3, 4,
5 and 6 so that air may enter through the holes in the lower part of the case b
to keep the fuel burning.

page_text: When the stove a. b is being used for purposes not associated with the canteen
it will be supported by legs hinged thereto and formed of strong wire which when
not in use will fold under the bottom or around the sides of the part b.
The fuel which is used with this apparatus is made into flat circular cakes c
one of which is shown in position at Figures 3, 4, 5 and 6 and separately at Fig. 7;
these cakes have a hole c through the centre and projections c, upon the surface.
These projections enable the whole cake to become ignited and glowing in a
rapid manner as the combustion takes place rapidly along the. same.
The composition of the cakes of fuel is as follows:-
not in use will fold under the bottom or around the sides of the part b.
The fuel which is used with this apparatus is made into flat circular cakes c
one of which is shown in position at Figures 3, 4, 5 and 6 and separately at Fig. 7;
these cakes have a hole c through the centre and projections 2, upon the surface.
These projections enable the whole cake to become ignited and glowing in a
rapid manner as the combustion takes place rapidly along the same.
The composition of the cakes of fuel is as follows:-
Charcoal, 4 ounces.
Potassium Chlorate or other like material, 44, grains,
Gum acacia or other similar gum, 127, grains.
per cent of Tow or other fibrous material,
Water, 2, ounces.
These materials are well mixed together and moulded preferably into the form
shown.
These cakes may be ignited by an ordinary match or they may be provided with
a patch of igniting material similar to that used on safety or other matches.
An annular cake of dessicated soup or other food material may be packed with
a cake of fuel and a cylinder of chocolate or tea or coffee essence may be placed
through the centre of these cakes so that no space is wasted. These packets of
food material and fuel may be carried in the interior of the canteen when on
the march.
It will be understood that when it is desired to use the frying pan d³ the
boiling utensil d is removed from the case and the frying pan d³ will be placed
inside the case with the handle d projecting through one of the slots a².
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. A warming or cooking apparatus consisting of an upper case or cover a
provided with loops a¹ and formed with slots a3 and a lower case or cover having
perforations in the bottom and around the lower part of the sides and provided
with hinged bars b', the whole arranged to receive the cake of fuel and the cooking
utensil.
2. A cake of fuel for use with the apparatus characterized by claim 1, consisting
of the following materials in about the proportions stated. Charcoal 4 ounces,
Potassium Chlorate or other like material 44 grains, Gum Acacia or other similar
gum 127 grains, Tow or other fibrous material 1 per cent, and 2 ounces of water
mixed and formed into cakes of suitable size and shape.
