PROVISIONAL SPECIFICATION.
Improvements in Artificial Fuel.
I, CHARLES JAMES LUNGLEY of Chestnut Lodge, The Green, Stratford, in the
County of. Essex, Gentleman, do hereby declare the nature of this invention to be
as follows:
According to this invention I solidify paraffin oil by heating and mixing it with
common soap. Although this mixture is solid when cold, it again liquefies on
becoming heated. To prevent this and to retain the fuel in the form of blocks
when in the fire I add absorbent materials such as flour and lime to the mixture
of paraffin oil and soap whilst in a heated state. The material thus produced can
be moulded into blocks which do not break up when heated.
In addition to the materials above mentioned I sometimes use small coal, saw-
dust or the like.

COMPLETE SPECIFICATION.
Improvements in Artificial Fuel.
I, CHARLES JAMES LUNGLEY of Chestnut Lodge, The Green, Stratford in the
County of Essex Gentleman do hereby declare the nature of this Invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
The object of my Invention is to produce from paraffin oil a solid fuel which
can be used without any special appliances or precautions in ordinary fire places
and furnaces in which coal is usually burnt.
According to this Invention I solidify paraffin oil by heating and mixing it
with common soap. Although this mixture is solid when cold it again liquefies
on becoming heated. To prevent this and to retain the fuel in the form of blocks
when in the fire I add absorbent materials such as flour and lime to the mixture
of paraffin oil and soap whilst in a heated state. The material thus produced can
be moulded into blocks which do not break up when heated.
In addition to the materials above mentioned I sometimes use small coal, saw-
dust or the like.
1 take the paraffin oil in the cheapest form in which it is obtainable, it may be
as crude petroleum and by the aid of heat 1 dissolve soap in it.
Yellow soap is
suitable and I use it in the proportion of one part by weight of soap to nine
parts of paraffin oil. When these materials are well mixed and are heated to the
boiling point of the oil I add finely powdered freshly slaked lime in the propor-
tion of two parts by weight. Also together with the lime I preferably add one
half part of flour but for the sake of economy the flour may be omitted. In place
of lime other absorbent powders such for example as chalk dust may be employed
but I know of none which serves the purpose so well as lime. By the means
described obtain a mixture of putty like consistency which may by itself be
moulded into blocks and used as fuel. In most cases however it is preferable to
incorporate with it some other combustible material, such as coal dust. For this
purpose I take the mixture whilst still hot and mix it in a mortar mill with
twenty four parts of coal dust; 1 then mould the compound into blocks as is now
done in making what is known as Patent Fuel. The blocks after leaving the
moulds will rapidly harden. Or sometimes in place of coal dust I use sawdust
say three parts; this composition forms a fuel which may be moulded into small
[Price 4d1

sawdust I may use other combustible refuse such as the dross
fibre, dried peat and the like.
Or in place of
from cocoa nut
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. An artificial fuel substantially as described composed of or containing a
mixture of paraffin oil, soap and lime with or without flour.
2. An artificial fuel substantially as described composed of or containing paraffin
oil, soap, lime and coal dust.
3. An artificial fuel substantially as described composed of or containing paraffin oil,
soap, lime, and sawdust or like material.
4. An artificial fuel made in accordance with either of the preceding claims
with the exception of the substitution for lime of some other absorbent powder.
