in the County of Surrey, Civil Engineer, for the Invention of "IM-
Sealed the 5th December 1873, and dated the 27th June 1873.
PROVISIONAL SPECIFICATION left by the said James Hunt at the
Office of the Commissioners of Patents, with his Petition, on the
27th June 1873.
I, JAMES HUNT, of the Ewell Powder Mills, Ewell, in the County of
Surrey, Civil Engineer, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN THE MANUFACTURE OF ARTIFICIAL FUEL," to be as
follows:-
This Invention has for its object improvements in the manufacture of
artificial fucl. For this purpose I mix peat or peat carth with coal or
coke dust, breeze, lignite, or such like carbonaceous substances, and
grind them together in a grinding mill, edge runners being by preference
employed. By this means the mixed mass is brought to the consistency
of stiff clay, the coal, coak, or such like absorbing the moisture in the
peat.

page_text: The materials after being thus ground together may be moulded into
any shape required, or the cake of ground material may be used as fuel
without being moulded. -
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Hunt in the Great Seal Patent Offico
on the 24th December 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
HUNT, of the Ewell Powder Mills, Ewell, in the County of Surrey,
Civil Engineer, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of June, in the year of our
Lord One thousand eight hundred and seventy-three, in the thirty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said James Hunt, Her special license that I, the
said James Hunt, my executors, administrators, and assigns, or such
others as I, the said James Hunt, 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, use, 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
ARTIFICIAL FUEL," upon the condition (amongst others) that I, the said
James Hunt, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, 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 James Hunt, do hereby declare
the nature of the said Invention, and in what manner the same is to be
-

page_text: performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
This Invention has for its object improvements in the manufacture of
artificial fuel. For this purpose I take peat or peat carth, either as it is
dug, or peat which has been disintegrated by passing it through a pug
mill or otherwise, and mix it in about equal proportions with coal or
coke dust, brecze, lignite, or such like carbonaceous substances, and
grind them together in a grinding mill, edge runners being by preference
employed. By this means the mixed mass is brought to the consistency
of stiff clay, the coal, coke, or such like absorbing the moisture in the
peat.
The materials after being thus ground together may be moulded into
any shape required by any ordinary brick making machinery, and the
bricks or blocks so made, afterwards dried, by preference, upon a drying
floor similar to that used for drying malt, or the cake of ground material
may simply be cut up into lumps suitable for being used as fuel without
being moulded.
The moulded blocks or the lumps of artificial fuel made as above
described become when dried hard and waterproof.
Having thus described the nature of my Invention and the manner of
performing the same, I would have it understood that I claim the manu-
facture of artificial fuel by grinding together peat or peat earth, with
coal or coke dust, breeze, lignite, or such like carbonaceous substances
as hercin described.
In witness whereof, I, the said James Hunt have hereunto set
my hand and seal, this Twenty-third day of December, in the
year of our Lord One thousand eight hundred and seventy-
three.
