PROVISIONAL SPECIFICATION left by the said Henry Rollinson at the
Office of the Commissioners of Patents, with his Petition, on the

I, HENRY ROLLINSON, of Stepney, in the County of Middlesex, do hereby
declare the nature of the said Invention for "AN ARTIFICIAL FUEL," to be as
follows (that is to say) :-
-
My Invention, having reference to the manufacture of an improved fuel
for the general purposes for which fuel is employed, which may also be used for
kindling or igniting fires, to be called "bituminised fuel," consists in employing
for the above purpose a combination of the following vegetable and hydro-
carbonaceous materials, namely, coal pitch, breeze with or without ashes,
broken coke, or sawdust, to which may be added coal tar, Stockholm tar,
Stockholm pitch, resin, or similar liquid or solid bodies capable of burning.
The above materials should be heated by means of a furnace or otherwise,
and moulded into suitable blocks, and submitted to pressure, if required.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
ROLLINSON, of Stepney, in the County of Middlesex, send greeting.
WHEREAS IIer most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of June, in the year of our Lord One
thousand eight hundred and fifty-eight, in the twenty-first year of ller reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Henry Rollinson, Her special licence that I, the said Henry Rollinson, my
executors, administrators, and assigns, or such others as I, the said Henry
Rollinson, 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 "AN ARTIFICIAL FUEL,"
upon the condition (amongst others) that I, the said Henry Rollinson, 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 per-
formed, 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 Henry Rollinson, do hereby declare
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 the following
statement (that is to say):-
My Invention, having reference to the manufacture of an improved fuel
for the general purposes for which fuel is employed, which may also be used
for kindling or igniting fires, to be called bituminized fuel, consists in employing
for the above purpose combinations of the following vegetable and hydro-car-
bonaceous materials, namely, coal pitch, breese with or without aslies, broken
or crushed coke, or sawdust, to which may be added Stockholm pitch, resin,
or similar substances capable of burning, the above materials being heated
by means of a furnace or otherwise, and moulded into suitable blocks, and
submitted to pressure, if required.
But in order that this my said Invention may be more fully understood

page_text: and readily carried into effect, I now proceed to describe in detail the mode
in which the same is to be performed (that is to say):-
I cause the said fuel to be composed in the proportion of one part of coal
pitch to three parts of breese, or one part of coal pitch to three parts of
crushed coke, or either of the said combinations may be employed with the
addition of any of the above-mentioned materials, the said materials being
worked together in a heated state until the temperature be sufficiently raised
to liquify the pitch or other hydro-carbonaceous substances, and enable the
ingredients to be thoroughly mixed or incorporated, and moulded into suitable
blocks or cakes for stowage or otherwise, for which purpose a furnace provided
with a tray top or receptacle on a level with the ground may be employed, and
the materials placed in the said tray top or receptacle, and heat supplied
thereto through the medium of under-ground flues, or otherwise. The
materials, when heated as above described, have then to be placed in suitable
moulds, and pressure applied thereto, if required, and allowed to remain
until sufficiently cool and hard for removal, by which they are rendered fit
for use.
Having now fully described and ascertained the nature of this my said
Invention, and the manner in which the same is to be performed and carried
into effect, I would have it clearly understood that I do not intend to confine
myself to the precise details herein-before described, as the same. may be
varied without departing from the general principle of this my said Invention;
but that which I do claim as new and of my said Invention is the com-
bination and employment of the above-mentioned materials, in the manner and
for the purposes herein-before set forth and described.
In witness whereof, I, the said Henry Rollinson, have hercunto set
my hand and seal, this Ninth day of December, in the year of our
Lord One thousand eight hundred and fifty-eight.
Witness,
F. R. DARKIN CAMPBELL,
Clerk to Messrs. Weatherdon & Co.,
