PROVISIONAL SPECIFICATION.
The Manufacture of an Improved Artificial Fuel.
I, JOHN MORRIS, of 13, Flinton Street, Surrey Square, in the county of London,
Plumber, do hereby declare the nature of this invention to be as follows:-
My invention relates to the manufacture of a slow combustion, smokeless and
inodorous fuel.
In manufacturing my improved fuel I mix and combine the following ingredients,
videlicet, silicate of soda, nitrate of potassa, water, powdered charcoal, powdered
carbonate of lime and powdered binoxide-manganese.
The proportions which I have found to give good results in practice are the
following, videlicet :-to a solution of about,
18 per cent by weight of silicate of soda
I add about
53 per cent. by weight of powdered charcoal

powdered carbonate of lime, and
powdered binoxide-manganese.
The whole is intimately mixed and is then moulded by compression into the form
of briquettes, or bricks, or other suitably shaped blocks and thoroughly dried at a low
temperature.
The proportions given above are those which produce a fuel suitable for an
average rate of combustion, but the rate of combustion can be increased or diminished
by increasing or diminishing the percentage of the soda silicate.
My improved artificial fuel being smokeless and inodorous and giving off no
Doxious fumes can be burned without a flue and is therefore especially applicable for
warming carriages, for rooms and other places which have no flues, and is very
useful for heating greenhouses.

COMPLETE SPECIFICATION.
The Manufacture of an Improved Artificial Fuel.
1, JOHN MORRIS, of 13, Flinton Street, Surrey Square, in the County of London,
Plumber, 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 :-
My invention relates chiefly to the manufacture of a slow combustion smokeless
and inodorous fuel.
In manufacturing my improved smokeless and inodorous fuel I mix and combine
the following ingredients, videlicet, silicate of soda, nitrate of potassa, water,
powdered charcoal, powdered carbonate of lime and powdered binoxide-manganese.
In practice I have found an admixture of the ingredients in the proportions and
manner following to give good results, videlicet, to a solution of about

powdered carbonate of lime, and
powdered binoxide-manganese.
The whole is intimately mixed and is then moulded by compression into the form
of briquettes or bricks or other suitably shaped blocks and thoroughly dried at a low
temperature.
The proportions given above are those which produce a fuel suitable for an average
rate of combustion, but the rate of combustion can be increased or diminished-by
increasing or diminishing the percentage of the silicate of soda.
My said improved artificial fuel being smokeless and inodorous and giving off no
noxious fumes can be burned without a flue and is therefore especially applicable for
warming carriages, for rooms and other places which have no flues, and is very
useful for heating greenhouses.
In manufacturing a fuel for ordinary purposes and which is not necessarily non-
smokeless, I mix and combine about 240 pounds of carbonate of lime, 1 cwt.
(112 pounds) of silicate of soda, 288 lbs. of water and about 1 ton of coal dust which
is then moulded into briquettes or blocks as above named.
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.) The described improved smokeless and inodorous artificial fuel formed by
mixing and combining the above named ingredients in about the proportions
mentioned and then compressing the composition into blocks, substantially as set
forth.
(2.) The described improved artificial fuel for ordinary purposes formed by
mixing and combining carbonate of lime, silicate of soda, water and coal in about the
proportions mentioned and then compressing the composition into blocks, substantially
as set forth.
