Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
DAVIS HOSKOLD, of Cinderford, in the County of Gloucester, Mining
Engineer, and GEORGE PRINTY WHEELER, of Abinghall, in the said
County, Engineer, send greeting.
WHEREAS we are in possession of an Invention for "IMPROVEMENTS IN
THE MANUFACTURE OF ARTIFICIAL FUEL," and have petitioned Her Majesty
to grant unto us, our executors, administrators, and assigns, Her Royal

page_text: Letters Patent for the same, and have made solemn Declaration that we
believe that the said Invention will be of great pubic utility, that we are
the true and first Inventors thereof.
NOW KNOW YE, that we, the said Henry Davis Hoskold and George
Printy Wheeler, do hereby declare that the following Complete Speci-
fication, under our hands and seals, fully describes and ascertains the
nature of the said Invention, and in what manner the same is to be
performed, in and by the following statement:-
These improvements in the manufacture of artificial fuel consist in
preparing or manufacturing blocks to be used as fuel with the intention
that the same shall be fit and ready for immediate use free from odour,
not liable to spontaneous combustion, and burn with less smoke than
arises from ordinary fuel, and also shall produce a more powerful heat
at a cheaper rate than hitherto known.
We carry out our improvements in the following manner, that is to
say: We take small coal, coal dust, lime coal, slack, culm, or other
bitumenous substance, which we grind fine, and to this we add during
the process of grinding "coal shale clay," and by preference we make
choice of that particular shale which is always found associated with
coal of every kind under ground; this we intimately mix with the coal,
dust, slack, or culm, and pass the same into a mixing pan, when to the
substance mixed we add pulverized resin, a proportion of asphalt or
compact natural bitumen, to which a vegetable glue is added made in
the following manner:-To fifty gallons of water we add five pounds
avoirdupois of rice and five pounds avoirdupois of the glue or gluten
extracted from Indian corn meal or maize, which when boiled for half
an hour is fit for use. The above quantity in solution is used with the
above ingredients, and when thoroughly mixed together in the mixing
pan the whole is caused to adhere and form a compact paste, and can
then be moulded into blocks, which we do by pressing machinery, and
under such a pressure that the blocks will become solid. The paste thus
moulded into blocks is placed in a drying chamber or vessel in order to
be dessicated, when it becomes in a short time so hard as to bear carriage
to a considerable distance.
The following is a table of the proportions of the ingredients we prefer
to use, which will make a good strong fuel capable of sustaining a high
combustion, but we do not intend to limit ourselves to the precise
proportions herein-after stated.

page_text: 17 hundredweight avoirdupois of coal dust; 24 hundredweight avoir-
dupois of coal shale clay; five pounds avoirdupois of rice; 5 pounds
avoirdupois of Indian meal or maize gluten; 5 pounds avoirdupois of
pulverized resin; 20 pounds avoirdupois of asphalt.
Having now particularly described and ascertained the nature of the
said Invention, and what manner the same is to be performed, we hereby
declare that we claim as our Invention, the use in the manufacture of
artificial fuel, as herein-before described, of coal shale clay, Indian corn
meal, maize, or the gluten contained in them, rice or the vegetable glue
contained therein, though the use thereof is not absolutely necessary,
although we consider its adoption desirable, and asphalt and resin,
cither separately or in combination, whether used in a dry or other
condition.
In witness whereof, we, the said Henry Davis Hoskold and George
Printy Wheeler, have hercunto set our hands and scals, this
Fourth day of November, in the year of our Lord One thousand
eight hundred and sixty-eight.
Witness,
