TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
WALKER WOOD, of Blackweir, in the County of Glamorgan, Gentleman,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of February, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Henry Walker Wood, Her special licence that I, the said
Henry Walker Wood, my executors, administrators, and assigns, or such
others as I, the said Henry Walker Wood, 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, shouldand 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 CYLINDERS EXPOSED TO THE DIRECT ACTION OF FIRE, AND
EMPLOYED IN. THE MANUFACTURE OF ARTIFICIAL FUEL, AND IN HEATING AND DRYING
OTHER SUBSTANCES," upon the condition (amongst others) that I, the said
Henry Walker Wood, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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 Henry Walker Wood,do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the Drawings hereunto annexed,
that is to say:-
My Invention consists in constructing the lower part of the cylinders open
over so much of the extent thereof as is liable to injury from the fire, in
forming flanges round the opening, and in fixing in the opening one metal
plate or several separate metal plates; on any one or more of these plates
becoming worn it or they can be readily removed and replaced without the
necessity for removing the cylinder..

page_text: Figure 1 of the accompanying Drawings is a longitudinal section of a
cylinder fitted according to my Invention.
Figure 2 is a transverse section of the same through the line a, b, of
Figure 1; c is the cylinder having a portion of the lower part formed open,
and provided with a flange or flanges d, d, round the opening. A metal
plate or plates 6, 6, are inserted into the open part, and rest upon the flanges
d, d. When worn or burnt by the action of the fire, the plates are removed
and others substituted for them, and that without necessitating the removal
of the cylinder.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I do not limit myself to the
mode described of securing the movable plates, and that I claim constructing
cylinders exposed to the direct action of fire, and employed in the manufacture
of artificial fuel, and in heating and drying other substances with one or more
bottom plates capable of removal and replacement, substantially as herein-
before described.
In witness whereof, I, the said Henry Walker Wood, hath hereunto set
my hand and seal, this Twelfth day of August, One thousand eight
hundred and sixty-four.
HENRY WALKER WOOD. (L.S.)
