PROVISIONAL SPECIFICATION.
Improvements in and in connexion with Combustible Material,
suitable for Cooking Purposes.
I, STEFAN NIEWIAROWSKI, of 8, Danilowiczowka, Warsaw, Russia, Gentleman,
do hereby declare the nature of this invention to be as follows: —
-
This invention relates to what are hereinafter called cartridges suitable for
heating cooking apparatus and each comprising a case, box, or the like of suit-
able sheet-metal, as tinned sheet metal, and containing the combustible material
hereinafter described.
This combustible material is produced as follows. A small quantity of a
substance that yields up its oxygen readily is dissolved in alcohol and the liquid
thus obtained is combined mechanically with, or absorbed by, porous or absorb-
tive material, as cotton, asbestos, wood-cellulose, kieselguhr, or the like.
Owing to the presence of an oxygen-yielding body, the process of combustion
proceeds considerably quicker and more fiercely than under ordinary circum-
stances, so that, with the help of combustible material made in the manner
mentioned, liquids to be boiled or cooked can be brought to the required high
temperature much more quickly than can be done when the addition of an
oxygen-yielding substance is omitted.
The best substance to use for this purpose is picric acid, 0.5 to 2% of which
are dissolved in the alcohol that acts as the combustible material, and the
solution thus obtained is then absorbed by cotton or some other porous or
absorbtive material of the kind mentioned.
In order that material soaked with alcohol and prepared in the manner described
may be kept ready for use as long as desired, it is placed in sheet-metal cases
or boxes, which are hermetically sealed in any suitable manner, as by soldering.
When the contents are required for use, the lid of the box is cut through and
the contents forthwith ignited.

1. STEFAN NIEWIAROWSKI, of 8, Danilowiczowka, Warsaw, Russia, Gentleman,
do hereby declare the nature of this invention and in what manner the same

following statement:
This invention relates to what are hereinafter called cartridges suitable for
heating cooking apparatus and each comprising a case, box, or the like of suit-
able sheet-metal, as tinned sheet metal, and containing the combustible material
hereinafter described.
This combustible material is produced as follows. A small quantity of a
substance that yields up its oxygen readily is dissolved in alcohol and the liquid
thus obtained is absorbed by an absorbtive material, as cotton, asbestos, wood-
cellulose, kieselguhr, or the like.
Owing to the presence of an oxygen-yielding body, the process of combustion
proceeds considerably quicker and more fiercely than under ordinary circum-
stances, so that, with the help of combustible material made in the manner
mentioned, liquids to be boiled or cooked can be brought to the required high
temperature much more quickly than can be done when the addition of an
oxygen-yielding substance is omitted.
The best substance to use for this purpose is picric acid, 0.5 to 2% of which

material of the kind mentioned.
In order that material soaked with alcohol prepared in the manner described
may be kept ready for use as long as desired, it is placed in sheet-metal cases
or boxes, which are hermetically sealed in any suitable manner, as by soldering.
When the contents are required for use, the lid of the box is cut through and
the contents forthwith ignited.
.
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:-
A fuel-cartridge for cooking purposes or the heating of cooking apparatus
comprising a sheet-metal case which is hermetically sealed, as by soldering, and
contains a combustible material obtained by the absorption in an absorptive
material, as cotton, asbestos, or the like, of alcohol, in which is dissolved a sub-
stance, preferably picric acid, that yields oxygen readily.
