PROVISIONAL SPECIFICATION.
An Improved Composition of Artificial or Block Fuel.
I, CHARLES HAVELOCK MOWLL, of the Wellington Hall, Dover, in the County of
Kent, Coal Merchant, do hereby declare the nature of this Invention to be as
follows:-
My invention relates to an improved composition of artificial or block fuel
("Briquettes") with the object of lessening the friability of the blocks while
increasing their value as a combustible.
I take small coal or slack and combine it, (in proportions varying with the destined
use of the block and the quality of the material) with peat in a more or less divided
or pulverised state.
I may add to the mixture of coal and peat an adhesive or agglomerating substance,
pitch for example, and or cinders, ashes, or calcined coal, and slightly heat or moisten
the mixture before passing it to a suitable compressing machine. Or I may submit
the mixture of coal and peat without addition of adhesive matter to the compression
of the machine.
The compressing machine known as "Messengers" will be found very suitable for
forming my blocks or briquettes, which from the fibrous nature of the peat will be
less brittle than ordinary briquettes and will combine the combustible qualities of the
two fuels.

An Improved Composition of Artificial or Block Fuel.
I CHARLES HAVELOCK MOWLL, of The Wellington Hall, Dover in the County of
Kent, Coal Merchant, 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 to an improved composition of artificial or block fuel
("Briquettes") with the object of lessening the friability of the blocks while
increasing their value as a combustible.
I take small coal or slack and combine it, with peat in a more or less divided or
pulverised state.
I may add to the mixture of coal and peat an adhesive or agglomerating substance,
pitch for example, and or cinders ashes or calcined coal, and slightly heat or moisten
the mixture before passing it to a suitable compressing machine. Or I
may submit
the mixture of coal and peat without addition of adhesive matter to the compression
of the machine.
I now prefer to use slack and peat in about equal proportions and say 15 per cent.
of calcined coal or cinder ashes, when these are added to the slack and peat, and the
pitch or other adhesive substance I prefer to use, if at all, in very small quantity for
"Briquettes" for household purposes, say 5%; it will however be evident that these
proportions must greatly vary with the destined use of the block and the quality of
the materials used and therefore I do not limit myself thereto.
"
The compressing machine known as Messenger's" will be found very suitable
for forming my blocks or "briquettes," which from the fibrous nature of the peat
will be less brittle than ordinary "briquettes" and will combine the combustible
qualities of the two fuels.

page_text: 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 composition of artificial or block fuel by combining small coal or slack with
peat substantially as described.
2. The composition of artificial or block fuel by combining small coal or slack and
peat with pitch or other agglomerating substance substantially as described.
3. The composition of artificial or block fuel by combining small coal or slack and
peat with cinders ashes or calcined coal, and with or without pitch or other
agglomerating material substantially as described.
4. As a novel article of manufacture a "Briquette" or block of fuel composed of
small coal or slack and peat with or without addition of cinders ashes or calcined coal
or of agglomerating material.
