PROVISIONAL SPECIFICATION.
An Improved Solid Combustible, and Process of Manufacturing
the same.
We, LÉON DARDEL and HENRI BÉCOULET both of 16 Rue Drouot, Paris in
the Republic of France, Engineers, do hereby declare the nature of this invention
to be as follows:-
This invention has for its object an improved process for the solidification of
petroleum and oil of naphtha with the object of forming a new solid combustible
which is lighter, of much greater heating power, and cheaper in price than any
other solid combustible. It allows therefore of there being stored in less volume
and more particularly with less weight, a much more considerable source of heat,
which is, in many cases, of immense advantage.
Several attempts have already been made to produce solidified petroleum for
making briquettes or firelighters, but up to the present no industrial result has
been obtained owing to the absolutely defective composition of the mixture which
is employed.
Our improved process is based on the combined use of oil of naphtha, or of
petroleum (the oil of naphtha having the advantage of being the least expensive
and producing a greater number of calories) fir cones, or spent tan, soap, which
may preferably be resin soap, and pine soot, to which a small quantity of soda may
be added in certain cases.
The elements constituting the mixture vary in certain proportions but we
indicate, as having given us the best results, the following proportions :-
Oil of naphtha, or of petroleum
Resin soap, or the like
Fir cones, or speut tan
Soda, if employed
Pine soot
60 to 70%
-
-
19 to 15%

19 to 15%

.
The mixture is warmed over a flame which is capable of being regulated to
requiremente.
When it commences to solidify, it is poured onto a smooth surface, or into
moulds having the shape of briquettes and is allowed to cool, and is then removed
from the mould. When the mass has been run into sheets it is afterwards cut up.
It is preferable, in order to obtain a harder product, to run the substance into
moulds surrounded by a continuous circulation of cold water, and then to allow it
to dry in the air.
There is thus obtained a combustible, which, owing to its being solid, may be
employed instead of, and in place of any other solid combustible, and may be
charged as conveniently into coal boxes or bunkers.
The combustion is effected in a similar manner to that of any solid combustible,
and it has the further advantage of yielding a much less quantity of cinders.

We, LEON DARDEL and HENRI BÉCOULET, both of 16, Rue Drouot, Paris,
in the Republic of France, Engineers, 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 :-
This invention has for its object an improved process for the solidification of
petroleum and oil of naphtha with the object of forming a new solid combustible
which is lighter, of much greater heating power, and cheaper in price than any
other solid combustible. It allows therefore of there being stored in less volumé
and more particularly with less weight, a much more considerable source of heat,
which is, in many cases, of immense advantage.
Several attempts have already been made to produce solidified petroleum for
making briquettes or firelighters, but up to the present no industrial result has
been obtained owing to the absolutely defective composition of the mixture which
is employed.
Our improved process is based on the combined use of oil of naphtha, or of
petroleum (the oil of naphtha having the advantage of being the least expensive
and producing a greater number of culories) fir cones, or spent tan, soap, which
may preferably be resin soap, and pine soot, to which a small quantity of soda may
be added in certain cases.

The mixture is warmed over a flame which is capable of being regulated to
requirements.
When it commences to solidify, it is poured onto a smooth surface, or into
moulds having the shape of briquettes and is allowed to cool, and is then removed
from the mould. When the mass has been run into sheets it is afterwards cut up.
It is preferable, in order to obtain a harder product, to run the substance' into
moulds surrounded by a continuous circulation of cold water, and then to allow it
to dry in the air.
There is thus obtained a combustible, which, owing to its being solid, may be
employed instead of, and in place of any other solid combustible, and may be
charged as conveniently into coal boxes or bunkers.
The combustion is effected in a similar manner to that of any solid combustible,
and it has the further advantage of yielding a much less quantity of cinders.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is:-
1. An improved process for solidifying petroleum and oil of naphtha, consisting
in mixing whilst hot one or other of said materials with a suitable soap,
préférably resin soap, fir cones or spent tan, and soot, to which may be added a
small quantity of soda, about in the proportions herein before specified, the
mixture when made being run, the moment it commences to solidify, on or into

page_text: suitably shaped moulds preferably surrounded by a continuous circulation of
water, in which moulds it is allowed to cool, and being then removed from the
moulds and cut up into pieces of suitable form and dimensions; substantially as
hereinbefore described.
2. An improved solid combustible product obtained by solidifying petroleum or
oil of naphtha by mixing it with a suitable soap, preferably resin soap, fir cones
or spent tan, and soot to which may be added a small quantity of soda, all taken
respectively about in the proportions hereinbefore specified, such mixture being
first made whilst hot and then run on or into moulds of suitable form, preferably
surrounded with a continuous circulation of cold water, from which moulds it is
removed after cooling and then cut up into pieces of suitable form and dimensions;
substantially as hereinbefore described.
