A New or Improved Artificial Fuel.
I JABEZ HOLMES WOOD of 91c, Grosvenor Road Pimlico in the County of
Middlesex Gentleman do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide an extremely efficient while yet cheap
artificial fuel which can be used in cement works as well as for foundry work or in
boilers or for other purposes.
To carry out this object and to produce this fuel for use in cement works I take
of coke breeze or coke dust say 90 per cent. of pitch or other similar material say
75 per cent. of slurry or what is generally a mixture of carbonate of lime silica
and alumina say 2 per cent. of astatki or the semiliquid residue of petroleum after
it has been refined say 0.3 per cent. and of a suitable alkali such for example as
bicarbonate of soda say 02 per cent. and having thoroughly when and where required
pulverized these materials and then mixed them together in the aforesaid proportions
or thereabouts I subject the combined mass to a great heat and then in a press or
otherwise to a very heavy pressure whereby these materials are properly amalgamated
and united and then the desired blocks or briquettes can be made therefrom in any
usual manner.
When this fuel is intended for use in foundries or in boilers or otherwise I
preferably omit the slurry and instead thereof I can increase the proportion of the
alkali and add a small proportion of slaked lime.
When this fuel is intended for use in hoilers and for many or most other purposes
I can when I may desiré substitute coal for the aforesaid coke.

COMPLETE SPECIFICATION.
A New or Improved Artificial Fuel.
I JABEZ HOLMES WOOD of 91c, Grosvenor Road Pimlico in the County of
Middlesex Gentleman 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 :-
The object of this my invention is to produce and provide for use an extremely
efficient and yet cheap artificial fuel which will be suitable for and can be used in
Portland cement works and also in foundries for foundry work and in boilers and
for domestic and other purposes.
To carry out this object and to produce this my artificial fuel for use in say
Portland cement works I proceed as a general rule and under normal conditions in
the following manner.
I take of coke breeze or coke dust 90 per centum of pitch or other similar
material 75 per centum of what is known as and commonly called slurry or that is
to say a plastic admixture of carbonate of lime silica and alumina 2 per centum of
astatki or the semiliquid residue of petroleum after it has been refined 0.375 per
centum and of a suitable alkali such for example as soda or potash or bicarbonate of
soda which alkalies I consider the most suitable for my purposes 0.125 per centum.
When the coke aforesaid has been burnt or is very hard as for example is frequently
the case when this coke has been produced or created in coke ovens it generally
requires more of the binding material and when and wheresoever this is necessary or
even expedient I can increase the aforesaid proportion of the pitch or other material
073

page_text: to even 10 per centum or more but in all cases I preferably do not use more of
this pitch or other material than is sufficient to allow the same properly to exercise
its binding qualities on the coke. Again when rapid combustion is desired or on
other occasions of a similar or other character I can increase the aforesaid proportion
of the astatki to even 0.75 per centum or more. Again when the other constituent
materials of this fuel are of good quality and the agglomeration thereof can be
satisfactorily effected and the combustibility thereof can be predicated or on other
occasions when it may be expedient or desirable so to do I may find it convenient and
proper slightly to reduce the aforesaid proportions of the pitch or other material and
of the astatki. I preferably use the aforesaid slurry in the plastic condition while the
other constituent inaterials of this fuel that is to say those of them that are dry are
invariably used in a thoroughly pulverized condition.
I then proceed to produce froin and by these materials aforesaid my artificial fuel
and to manufacture the same in readiness for use in the following manner and I can
use in and for this purpose any of the ordinary and well known machines and
apparatus that will perform and effect and carry out the treatment hereinafter
described.
The coke breeze or coke dust and the pitch or other material are separately'
mixed together in the aforesaid proportions or thereabouts and the slurry the astatki
and the alkali are also separately mixed together in the aforesaid proportions or
thereabouts. The coke mixture and the slurry mixture are then in the aforesaid
proportions or thereabouts fed into a chamber wherein they are subjected to a great
heat through the instrumentality or by means of superheated steam and wherein by
any suitable mixing or stirring appliances or apparatus they are thoroughly and
completely mixed together and all the aforesaid constituent materials of this fuel are
properly amalgamated. The combined mass then is removed from or passes out of
this chamber and is allowed or as perhaps is preferable is caused to cool down it,
may be by a fan when in and by suitable moulds and presses or other usual and
ordinary appliances or apparatus this mass is formed into the blocks or bricks or
briquettes required under pressure or otherwise which blocks or bricks or briquettes
may be of any desired shape and size and this my improved artificial fuel is ready
for use.
When this fuel is intended for use in foundries or in boilers or, in many other
places other than Portland cement works I can if and when I may deem it expedient
so to do omit the aforesaid proportion of the slurry and instead thereof I can or may
increase the aforesaid proportion of the astatki and also add a small proportion of
slaked lime.
When this fuel is intended for use in and for domestic purposes and on other
occasions I can if and when I may deem it expedient so to do substitute a small
proportion of coal also pulverized for a corresponding or other proportion of the
coke aforesaid in which cases it will generally be found that the aforesaid proportion
of the pitch or other material can be in some small degree reduced with advantage.
i
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed 1 declare that what I
claiin is
The artificial fuel substantially as herein before described and set forth.
