Improvements in Fuel for Spirit Stoves and in the Method of Making
the same.
We, SPIRITINE LIMITED, of No. 5, Carteret Street, in the City of Westminster,
Manufacturers, do hereby declare the nature of this invention (a communication
to us from abroad by Bernhard Hoffmann, of No. 23, Rue Le Peletier, Paris, in
the French Republic, Engineer) to be as follows:-
This invention relates to fuel for use in a spirit stove or receptacle and to the
method of making such fuel.
The invention consists essentially in the employment of stearine together with
a small quantity of carbonate of soda tó absorb alcohol so that the latter is in an
occluded condition thereby permitting of the convenient transport of the fuel
and of manipulating or handling the same without danger.
Instead of, or it may be together with the before mentioned stearine, other
animal or vegetable fatty substances may be used; and instead of using carbonate
of soda, carbonate of potash, caustic soda, caustic potash, ammonia or any other
alkali may be used. Further, instead of alcohol it is obvious methylated spirit
or spirits of wine of various strengths may be used.
As an example it may be stated that the following are suitable proportions of
the ingredients.
Stearine
45 parts.
Carbonate of Soda
'5
95'
Methylated spirits
"
33
In using the above ingredients the stearine is melted by heat and carbonate of
soda is added, the liquid mixture is agitated or stirred until the carbonate of soda
is dissolved and then the whole is poured into a vessel such as a digester. The
spirit is then poured in and the vessel is heated for, say, an hour, the contents
being agitated meanwhile. If the vessel used be enclosed, gasefied spirit does
not escape, and, as a matter of fact, if an open vessel be used, a great proportion
of the spirit is lost by evaporation besides rendering the process dangerous.

the same.
We, SPIRITINE LIMITED, of No. 5, Carteret Street, in the City of Westminster,
Manufacturers (a communication to us from abroad by Bernhard Hoffmann, of
No. 23, Rue Le Peletier, Paris, in the French Republic, Engineer) do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:
This invention relates to fuel for use in a spirit stove or receptacle and to the
method of making such fuel.

and
or
Instead of, or it may be together with the before mentioned stearing other
animal or vegetable fatty substances may be used, for example a small proportion
of an animal fatty substance such as beeswax a. small proportion of a vege-
table fatty substance such as cotton seed oil stearine or carnauba wax may be
employed together with the stearine; and instead of using carbonate of soda,
carbonate of potash, caustic soda, caustic potash, ammonia or any other alkali may
be used. Further instead of using alcohol it is obvious that methylated spirit.
(which consists of wood naphtha and spirits of wine) or wood naphtha alone or
spirits of wine alone of various strengths may be used.
As an example it may be stated that the following are suitable proportions of
the ingredients, but it is evident that the materials and the proportions may be
varied as hereinbefore indicated without departing from the invention.

In using the above ingredients the stearine is melted by heat and carbonate of
soda is added, the liquid mixture is agitated or stirred until the carbonate of soda
is dissolved and then the whole is poured into a vessel such as a digester. The
spirit is then poured in and the vessel is heated for, say, an hour, the contents
being agitated meanwhile if desired. If the vessel used be enclosed, gasefied
spirit does not escape and as a matter of fact if an open vessel be used a great
proportion of the spirit is lost by evaporation besides rendering the process
dangerous. The resulting liquid is then conducted or put into vessels of any
required shape in which it soon hardens or solidifies.
Having nor particularly described and ascertained the nature of the said
invention (as communicated to us by our foreign correspondent) and in what
manner the same is to be performed, we declare that what claim is:-
1. An improved fuel consisting of alcohol or the like occluded in a soap-like
mixture of stearine and an alkali substantially as described.
2. An improved fuel consisting of alcohol or the like occluded in a soap-like
mixture of stearine and other animal or vegetable fatty matter and an alkali
substantially as described.

3. The method of manufacturing an improved fuel consisting in subjecting
alcohol or the like, stearine and other animal vegetable fatty matter and an
alkali to heat and agitating same substantially as described.
