Year: 1850

page_text: WOOD'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I HENRY
WALKER WOOD, of Briton Ferry, near Neath, Glamorganshire, Gentleman,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Seventh day of
December (One thousand eight hundred and fifty), in the fourteenth year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Henry Walker Wood, my exors, admors, and assigns, Her
especial license, full power, sole privilege and authority, that I, the said Henry
Walker Wood, my exors, adñññors, and assigns, or such others as I, the said
Henry Walker Wood, my exors, admors, or assigns, should at any time
agree with, and no others, from time to time and at all times during the term
of years therein expressed, should and lawfully might make, use, exercise,
and vend, within England, Wales, and the Town of Berwick-upon-Tweed,
my Invention of "IMPROVEMENTS IN THE MANUFACTURE OF FUEL;" in which
said Letters Patent is contained a proviso that I, the said Henry Walker
Wood, shall cause a particular description of the nature of my said Invention,
and in what manner the same is to be performed, by an instrument in writing
under my hand and seal, to be inrolled in Her said Majesty's High Court
of Chancery, within six calendar months next and immediately after the date
of the said in part recited Letters Patent, as in and by the same, reference
being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Henry Walker Wood, do hereby declare that the nature of my said Inven-
tion, and the manner in which the same is to be performed, are fully described
and ascertained in and by the following statement thereof, that is to say :—
.
The fuel to which my improvements relate is of two kinds; one kind is made
of coal, mixed with some other substance or substances, such as pitch, coal
tar, resin, or other pitchey, fatty, or resinous substance or substances; the
other kind is made of coke mixed with the above-mentioned substance or
substances. My improvements relate to the time of heating the coal or coke
used for the purpose of such admixture, that is to say, in the case of fuel made
of coal so mixed, my improvement consists in making the coal hot before the
other substance or substances so to be mixed with it are applied to it. In the
case of fuel made with coke so mixed, my improvement consists in applying
the other substance or substances to the coke whilst the coke remains in a hot
state after being made."
The way in which I manufacture fuel made of coal so mixed is as follows:-
I take coal sufficiently small for the purpose and make it quite hot, I. then
put it into a mixing machine, made with a spindle and arms like a conimon
pug mill. I then add such a proportion of pitch, coal tar, resin, or other
pitchy, fatty, or resinous substance or substances as the purpose for which the
fuel is wanted may require, and when the whole is perfectly and intimately
mixed I press it off in lumps of any size suitable for the purposes for which it
may be needed. The way in which I manufacture fuel made of coke so mixed
is precisely similar to the above made of making fuel of coal so mixed, with
this exception that I use the cake quite hot as it comes from the overis, and
after passing it through rollers, if needed, in order to make it sufficiently small,
I deal with it in the manner above described.
I do not claim the use of any particular form of ovens or other apparatus
for heating coal or making coke, nor do I claim any particular form of pug
mill, presses or rollers, nor do I claim the exclusive use of any particular
pitchy, fatty, or resinous substance or substances for the purposes of the above
admixture,, but what I claim as my Invention is the making of fuel with coal
or coke in combination with same pitchy, fatty, or resinous súbstance or
substances necessary for making a good and serviceable fuel by applying heat
to such coal or coke previously to the admixture or combination thereof with
such other substance or substances. And I also claim as my Invention the
exclusive use of this preparation or any other preparation of a similar characte
for the purpose of preventing the decomposition of coal, and of preserving i

page_text: by enclosing coal in a covering of this mixture, or by a covering with any other
material better suited for the purpose.
In witness whereof, I, the said Henry Walker Wood, have hereunto
set my hand and seal, this Second day of June, in the year of
our Lord One thousand eight hundred and fifty-one.
