Complete Specification Left, 8th Dec., 1892-Accepted, 14th Jan., 1893
PROVISIONAL SPECIFICATION.
Improvements in Artificial Fuel.
We JOSHUA SWALLOW, of Hillsyard Victoria Road, Leeds, Operative Chemist,
and CHARLES WEST, of 29 Hills Street Beeston Hill, Leeds, both in the County
of York, Commercial Traveller, do hereby declare the nature of this invention to
be as follows:-
--
This invention relates to improvements in the manufacture of artificial fuel, such
as briquettes and its object is to dispense with the use of resin and pitch usually
employed in their manufacture, thereby cheapening the cost and producing a
briquette free from the fumes arising from the combustion of pitch and resin.
According to this invention the briquettes are composed of coal (either ground
or ordinary smudge or slack) or coke, or shale combined with lime, Indian meal
and sugar or with lime and alum only in the proportion of say about nineteen
hundredweights of coal or coke, or shale, to say about one hundredweight of lime
Indian meal and sugar combined, or of lime and alum only.
These ingredients after being well mixed together are mixed with water into a
sémi plastic state, and are then pressed in a mould by any suitable machinery when
they are ready for use.

COMPLETE SPECIFICATION.
Improvements in Artificial Fuel.
We, JOSHUA SWALLOW of 20 Hills Yard, Victoria Road, Leeds, Operative
Chemist, and CHARLES WEST of 29 Hill Street Beeston Hill, Leeds, both in the
County of York, Commercial Traveller, 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 relates to improvements in the manufacture of artificial fuel, such
as briquettes, and its object is to dispense with the use of resin and pitch usually
employed in their manufacture, thereby cheapening the cost of manufacture, and at
the same time producing a briquette which in burning will be free from the fumes
arising from the combustion of pitch and resin.
According to this invention the briquettes or other artificial fuel is or are
composed of coal (either ground or ordinary smudge or slack or ground coke, or
shale, or of coal, coke, or the like, combined with lime which has been previously
slacked or moistened with water to prevent it bursting the briquette after being
pressed) Indian meal and sugar or of lime and alum only combined with ground
coal, or coke, or shale or with coal, coke and shale combined.
The proportion in which we prefer to use the above named ingredients may be as
follows: To say about nineteen hundredweights of coal, or coke, or shale, or of
coal, coke and shale combined, is added say about one hundredweight of lime,
Indian meal and sugar combined or about a hundredweight of lime, Indian meal,
and sugar in equal proportions or one hundredweight of lime and alum only in
equal quantities. We would have it understood that the above named proportions
may be varied or modified as circumstances require.
The above named ingredients after being well mixed together are moistened with
water into a semiplastic state (or nearly so) so as to easily ball in the hand, and
F

page_text: they are then pressed in a mould by any suitable machinery when they are ready
for use.
Although we have described the meal we prefer using as being what is
commercially known as Indian meal, which we find answers well in practice, yet we
would have it distinctly understood that any other kind of meal or floury substance
obtained from the grinding of grain, such as wheat, oats, peas, beans, corn, barley,
and the like may be employed thereof and as an equivalent therefor, for obtaining
like binding or paste forming results, also in place of lime any material or
materials having like chemical properties may also be used in place thereof as
a flux.
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. In the manufacture of artificial fuel the use and combination of coal (either
ground or ordinary smudge or slack) or of ground coke or shale, or of ground coal,
coke, and shale combined with lime meal and sugar, or with lime and alum only,
said ingredients being mixed together in or about the proportions given, moistened
with water and when required pressed, substantially as herein described.
2. A briquette composed of ground coal, or coke, or shale, lime, meal, and sugar,
or of coal, coke, or the like, (separately or combined) lime and alum said
ingredients being moistened with water and pressed to shape, substantially as herein
described.
