FUEL," to bo as follows :——
•
'
My Invention relates to the preparation of an artificial fuel from peat,
turf, or bog, which, according to my Invention, I combine either with
tar, pitch, resin, asphaltum, or other resinous or bituminous substance
or oil. Tho poat or turf is first dried by exposure or by artificial heat,
and is then immersed or soaked with one or other of the above sub-
stances, and afterwards submitted to pressure in moulds to thoroughly
impregnato it with the tar or other substance, and express any super-
fluity, and after being again dried is fit for use.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of February, in tho
year of our Lord One thousand eight hundred and seventy-threo, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Thomas 'Cadett, Her special licence 1
that I, the said Thomas Cadett, my executors, administrators, and assigns,
or such others as I, the said Thomas Cadett, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to
time and at all times thercafter during the term therein expressed, should
and lawfully might make, use, exercise, and vend, within the United 1
Kingdom of Great Britain and Ireland, the Ohannel Islands, and Isle of
Man, an Invention for "AN IMPROVED ARTIFICIAL FUEL," upon the con-
dition (amongst others) that I, the said Thomas Cadett, my executors
or administrators, by an instrument in writing under my, or their, or ono
of their hands and scals, should particularly describe and ascertain the 2
nature of the said Invention, and in what manner the samo was to be
performed, and cause the same to be filed in the Great Seal Patent
Offico within six calendar months next and immediately after the dato
of the said Letters Patent.
NOW KNOW, YE, that I, the said Thomas Cadett, do hereby declare 2
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by tho
following statement, that is to say :——
My Invention relates to the preparation of an artificial fuel from the
substance known as peat, turf, or bog, and for this purpose I utilize the 3
coal tar resulting from the manufacture of coal gas. The peat is cut in
the usual way in the form of bricks, and is thoroughly dried by exposure
to the air, and is then immersed for about two or three minutes in the
coal tar. A longer immersion is not desirable, because if the tar is in
excess a great quantity of smoke will be produced. when the fuel is 3
burnt. In frosty weather it is desirablo to heat the coal tar to render it

page_text: moro fluid. The blocks of peat having been immersed as above men-
tioned are again dried by exposure to the air. When dry they are fit for
use, or by coating them with sawdust they may be used immediately
after being immersed in the tar without the subsequent drying.
Пaving described the nature of my Invention, and the manner in
which the same is to bo performed, I declare that what I claim as my
Invention to be protected by the herein-before in part recited Letters
Patent is, the production of an artificial fuel composed of peat impreg-
nated with coal tar, as herein described.
In witness whereof, I, the said Thomas Cadett, have hereunto set
my hand and seal, this Twenty-eighth day of August, in tho.
year of our Lord One thousand eight hundred and seventy-
threo.
