PREPARATION OF ARTIFICIAL FUEL FROM CULM OR COAL DUST, AND IN APPA- RATUS TO BE EMPLOYED IN THE MOULDING OF ARTIFICIAL FUEL.
Year: 1874

page_text: LETTERS PATENT to Francis Page, of Thurles, in the County of
"IMPROVEMENTS IN THE
Tipperary, Ireland, for the Invention of
PREPARATION OF ARTIFICIAL FUEL FROM CULM OR COAL DUST, AND IN APPA-
RATUS TO BE EMPLOYED IN THE MOULDING OF ARTIFICIAL FUEL.
I, FRANCIS PAGE, of Thurles, in the County of Tipperary, Ireland, do
hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE PREPARATION OF ARTIFICIAL FUEL FROM CULM OR COAL DUST, AND IN
APPARATUS TO BE EMPLOYED IN THE MOULDING OF ARTIFICIAL FUEL," to be as
follows

page_text: may also be applicable wholly or in part in cases wherein other coal dust
is employed.
When carrying my said Invention into effect I add to the said culm
or dust, lime, peat, clay, and a suitable proportion of water, and I may
also add some or all of the following substances, namely, starch, potatoes
or derivatives of potatoes, nitrate of potash, carbolic acid, and Condy's
fluid. I incorporate the several ingredients by suitable means, as for
example, by means of a mortar mill. When sufficiently incorporated I
mould the composition into blocks or lumps of a size suitable to be used
as fuel; or I supply the said composition to consumers, who may effect
such moulding.
According to a further part of my Invention I effect the moulding of
the said composition or of other artificial fuel by means of a hand
moulding apparatus, consisting of a cylindrical or other shaped mould
fitted with a piston for effecting the discharge of the moulded mass. I
have found that when using a cylindrical mould having sharp edges and
tapering internally the lumps or masses may be quickly formed by
plunging the open mouth of the mould into a mass of the mixture, and
by then forcing out the moulded mass by means of the aforesaid piston,
which is suitably formed, fitted, and arranged to be operated upon by
the hand. The lumps or masses so formed may be used at once or be
dried as may
be preferred or found to be most convenient.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Francis Page in the Great Seal Patent Office on the
14th October 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANCIS
PAGE, of Thurles, in the County of Tipperary, Ireland, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of April, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty.
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto the said Francis Page, Her special licence that
I, the said Francis Page, my executors, administrators, and assigns,

page_text: or such others as I, the said Francis Page, my executors, administrators,
and assigns, should at any time agree with, and no others, from time
to time and at all times thereafter during the term therein expressed,
should and lawfully might make, usc, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN THE Manufacture
OF FUEL FROM CULM OR COAL DUST, AND IN APPARATUS TO BE EMPLOYED IN THE
MOULDING OF ARTIFICIAL FUEL," upon the condition (amongst others) that
I, the said Francis Page, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said In-
vention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Francis Page, do hereby declare the
nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement and accompanying Drawings, that is to say :-
My Invention relates principally and in the first place to thic manu
facture of artificial or prepared fuel from culm or anthracite dust, but
may also be applicable wholly or in part in cases wherein other coal dust
is employed.
When carrying my said Invention into effect I add to the said culm
or dust limestone or lime, peat, clay, and a suitable proportion of water,
and I may also add some or all of the following substances, namely,
starch, potatoes or derivatives of potatoes, nitrate of potash, carbolic
acid, and Condy's fluid. The proportions of the several ingredients may
be greatly varied to suit the requirements or the capabilities of divers
localities. A mixture which I now consider to be suitable may consist
of the following ingredients, namely, culm, one ton; limestone, ground
or crushed, three hundredweight; peat in a wet state, five hundred-
weight; clay, one hundredweight. To the foregoing I may add about
one pint of carbolic acid, and if circumstances permit I add about. ono
hundredweight of potatoes, starch in quantity corresponding to the yield
of about one hundredweight of potatoes." I incorporate the several
ingredients by suitable means, as for example, by means of a mortar mill.

page_text: And, Lastly. The moulding apparatus, substantially as and for the
purpose set forth and indicated herein-before and by the accompanying
Drawing.
In witness whereof, I, the said Francis Page, have hereunto set
my hand and seal, this Twelfth day of October, in the year of
our Lord One thousand eight hundred and seventy-four.
Witness,
JERIMIAU DARGAN.
