Year: 1858

page_text: LETTERS PATENT to John Miles, of Risca, in the County of Monmouth,
Ironfounder, for the Invention of "IMPROVEMENTS IN ANNEALING POTS,
USED IN THE MANUFACTURE OF IRON, STEEL, AND OTHER METALS."
Sealed the 16th November 1858, and dated the 28th July 1858.
PROVISIONAL SPECIFICATION left, by the said John Miles at the
Office of the Commissioners of Patents, with his Petition, on the
28th July 1858.
I, JOHN MILES, of Risca, in the County of Monmouth, Ironfounder, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN AN-
NEALING POTS USED IN THE MANUFACTURE OF IRON, STEEL, AND OTHER METALS," to
be as follows:-
My Invention has for its object the prevention of injury to the pots by the
unequal expansion and contraction of the metal at the closed end thereof when
in use, and also the protection of the pot from collapsing at the open end.
For this purpose I construct the pot with two open ends, and I close the
end which is ordinarily closed by a solid casting, by means of a moveable lid
fitting loosely the interior of the pot, and resting on a ledge or rib formed
therein, being also confined between the said rib or ledge, and projections on
the outer end of the pot; and it is secured in its position by means of a key
or wedge passed between one or more of the projections and the lid; on the
sides of this lid are dovetailed grooves for the purpose of fitting over dove-
tailed projections on the interior of the pot. The lid when in its position is

page_text: sunk in such a manner as to leave a hollow space at the end or top of the pot,
which is luted with clay and filled up with dust or other non-conducting material
after the cover is placed upon it. The saucer or stand for the pot is con-
structed with guage pieces or projections on the plate or bottom on which the
pot stands, fitting the interior of the pot and protecting it from the tendency
to collapse. These guage pieces are also useful as guides for piling the plates
intended to be annealed on the saucer, so as to keep them in a position central
with the pot before the pot is placed over them.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Miles in the Great Seal Patent Office on the 27th
January 1859.
ΤΟ
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
MILES, of Risca, in the County of Monmouth, Ironfounder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of July, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of
Her reign, did, for Herself; Her heirs and successors, give and grant unto
me, the said John Miles, Her special license that I, the said John Miles,
my executors, administrators, and assigns, or such others as I, the said
John Miles, 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 "IMPROVEMENTS IN
ANNEALING POTS USED IN THE MANUFACTURE OF IRON, STEEL, AND OTHER METALS,"
upon the condition (amongst others) that I, the said John Miles, by an
instrument in writing under my hand and seal, should particularly 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 John Miles, 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, reference being had to the Drawings hereunto annexed, and to
the letters and figures marked thereon (that is to say):-

page_text: My Invention of "Improvements in Annealing Pots used in the manu-
facture of Iron, Steel, and other Metals," has for its object, the prevention of
injury to the pots by the unequal expansion and contraction of the metal at
the closed end thereof when in use, and also the protection of the pot from.
collapsing at the
open end.
For this purpose I construct the pot with two open ends, and I close the
end which is ordinarily closed by a solid casting, by means only of a moveable
lid, fitting loosely the interior of the pot and resting on a ledge or rib formed
therein, being also confined between the said rib or ledge and some projections
on the outer end of the pot; and it is secured in its position by means of a
key or wedge passed between one or more of the projections and the lid. On
the sides of this lid are dovetailed grooves for the purpose of fitting over dove-:
tailed projections on the interior of the pot. The lid when in its position is.
sunk in such a manner as to leave a hollow space at the end or top of the pot, .
which is luted with clay and filled up with dust or other non-conducting
material after the cover is placed upon it.
The saucer or stand for the pot is constructed with gauge pieces or projec-.
tions on the plate or bottom on which the pot stands, fitting the interior of the
pot, and protecting it from the tendency to collapse; these gauge pieces are
also useful as guides for piling the plates intended to be annealed on the
saucer, so as to keep them in a position central with the pot before the pot is
placed over them.
Having thus stated the nature of the said Invention, I proceed to describe.
more particularly in what manner the same is to be performed, by reference
to the accompanying Drawings, in which my improved mode of constructing
the annealing pots is represented.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a plan, and Fig. 2, a section of the moveable lid; Fig. 3 is a plan
of the saucer or stand for the pot; Fig. 4 is a plan of the pot shewing the
dovetailed and other projections or "snugs" for fastening the lid to the end
of the box; Fig. 5 is a longitudinal elevation of the pot; Fig. 6 is a cross
section of the pot and saucer; and Fig. 7 is a longitudinal section of the
pot.
In all these several Figures, the same letters of reference indicate corres-
ponding parts. a is the pot; b is the moveable lid, having a cross strengthening
rib c, also a dovetailed groove d on each side, and a groove e at the end;
ff, are dovetailed projections in the end of the pot, over which the dove-
tailed grooves d, d, fit, when the lid is applied to the pot; g, g, are projections

page_text: "
snugs," also formed in the end of the pot under which the lid is placed;
h is the ledge or rib on the inside of the pot on which the lid rests. The lid
is secured in its position by means of a key or wedge passed between one or
more of the projections g and the lid b; the lid, when thus secured, is covered
by a luting of clay, and the space between it and the end of the pot filled with
dust or other non-conducting material, so as to prevent the heat from escaping;
i is the saucer or stand for the pot; this saucer has gauge pieces or projections
k, k, formed on the upper surface of its plate, which, by fitting the interior of
the pot, as shewn at Fig. 6, and also in the opposite direction, as will be
obvious on reference to Fig. 3, will resist the tendency of the pot to collapse.
It will also be obvious on reference to Fig. 3, that these gauge pieces or
projections will serve as guides to facilitate the piling of the plates on the
saucer, so as to keep them in a position central with the pot ready for the
same to be placed over them.
Having thus described the nature of the said Invention, and in what manner
the same is to be performed, I would have it understood that what I claim as.
of my Invention is,-
First, the construction of annealing pots with two open ends, and the closing
of the one (which when the pot is in operation is the upper end) by means of
a moveable lid, as described.
And, secondly, the construction of the saucer or stand for the pot with
gauge pieces or projections to resist the tendency of the pot to collapse, and
also to facilitate the piling of the sheets of metal, as described.
In witness whereof, I, the said John Miles, have hereunto set my
hand and seal, the Twenty-sixth day of January, in the year of our
Lord One thousand eight hundred and fifty-nine.
Witness,
JOHN VAUGHAN,
Pontynister, Agent.
