IMPROVEMENTS, IN KEIRS
Year: 1868

page_text: LETTERS PATENT to Thomas Beeley, of Hyde, in the County of
Chester, for the Invention of "IMPROVEMENTS, IN KEIRS."
Sealed the 14th August 1868, and dated the 19th February 1868.
PROVISIONAL SPECIFICATION left by the said Thomas Beeley at
the Office of the Commissioners of Patents, with his Petition, on
the 19th February 1868.
I, THOMAS BEELEY, of Hyde, in the County of Chester, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN KEIRS,"
to be as follows:-
My Invention consists in introducing a flanged perforated pipe (which
I prefer to be of wrought iron) into the interior of such keirs as are
subjected to pressure. This pipe reaches from one end to the other of
the keir, and the flanges are attached or revitted to the end plates, thus
forming a strong stay, strengthening the keir in its weakest direction,
and thus preventing the explosions which so frequently takes place in
unstayed keirs. The pipe is perforated in order to admit the steam or
liquor. I am aware that it is not new to use a perforated pipe for this

page_text: purpose, but keirs so constructed have not been strengthened by stays,
and are very weak and liable to explode.
My Invention consists in making this pipe form a stay in order to
prevent explosion.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Beeley in the Great Seal Patent Office
on the 18th August 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
BEELEY, of Hyde, in the County of Chester, send greeting. .
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of February, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
first year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Thomas Beeley, Her special licence
that I, the said Thomas Beeley, my executors, administrators, and
assigns, or such other's as I, the said Thomas Beeley, 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 termi
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
KEIRS," upon the condition (amongst others) that I, the said Thomas
Beeley, 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 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 Thomas Beeley, do hereby declare
the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by
the following statement thereof, that is to say :-
My Invention consists in introducing a flanged perforated pipe (which
I prefer to be of wrought iron) into the interior of such keirs as are

page_text: subjected to pressure. This pipe reaches from one end to the other of
the keir, and the flanges are attached or rivetted to the end plates, thus
forming a strong stay, strengthening the keir in its weakest direction,
and thus preventing the explosions which so frequently take place in
unstayed keirs. The pipe is perforated in order to admit the steam or
liquor. I am aware that it is not new to use a perforated pipe for this
purpose, but keirs so constructed have not been strengthened by stays,
and are very weak and liable to explode.
My Invention consists in making this pipe form a stay in order to
prevent explosion.
In the accompanying Drawing a, a, is the outer shell of the keir;
b, b, is the perforated pipe which extends from one end of the keir to
the other, being flanged at the ends so as to be attached to the
eud plates.
In witness whercof, I, the said Thomas Beeley, have hereunto set
my hand and seal, this Seventeenth day of August, in the year
of our Lord One thousand eight hundred and sixty-eight.
THOMAS BEELEY. (L.S.)
