Year: 1859

page_text: LETTERS PATENT to George Bedson, of Manchester, in the County of
Lancaster, Manager for Messrs. R. and W. Johnson & Co., Iron Manu-
facturers for the Invention of "IMPROVEMENTS IN PUDDLING FURNACES"
Sealed the 5th June 1860, and dated the 14th December 1859.
PROVISIONAL SPECIFICATION left by the said George Bedson at the
Office of the Commissioners of Patents, with his Petition, on the
14th December 1859.
I, GEORGE BEDSON, of Manchester, in the County of Lancaster, Manager
for Messrs. R. and W. Johnson & Co., Iron Manufacturers, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN PUDDLING FURNACES,"
to be as follows:-
My Invention relates to a method of protecting the sides and bottom of
puddling furnaces. For this purpose I make them hollow, of wrought iron,
and I propose welding the parts together. Through the chamber or chambers
so formed water is caused to flow. The whole I construct as a portable
apparatus, capable of removal from the furnace.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Bedson in the Great Seal Patent Office on the
14th June 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
BEDSON, of Manchester, in the County of Lancaster, Manager for Messieurs
R. and W. Johnson and Company, Iron Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of December, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said George Bedson, Her special licence that I, the said George
Bedson, my executors, administrators, and assigns, or such others as I, the
said George Bedson, 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
PUDDLING FURNACES," upon the condition, amongst others, that I, the said George
Bedson, 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 George Bedson, 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 and accompanying Drawings, that is to say :-
My Invention consists in forming the bottoms and sides of puddling furnaces
of wrought iron hollow, constituting chambers, into and out of which a stream
of water is allowed to flow.
In the accompanying Drawing Fig. 1 represents a puddling furnace in
section, and Fig. 2 is a plan view of that part constructed according to my
improvements.
The furnace bottom is shewn at a formed of wrought-iron plates, the
sides 6 being constructed after the same manner, so that a water chamber
surrounds the iron while it is being puddled; at c is a pipe by which water is
supplied; and at d another pipe by which it is allowed to flow out. The
latter is shewn as carried upwards, and the escape takes place from the upper

page_text: end; the feed pipe, therefore, must contain an equal or superior column, so
that the water chamber may always be full, and the rapidity of the current
may be regulated by a stop-cock at e or other convenient situation.
The parts constituting the furnace bottom and sides may be put together by
angle iron and rivets, or by other ordinary means, or the whole may be
welded, so as to avoid the use of joints; and I would observe, as an advantage
of my Invention, that the said bottom and sides being a complete apparatus,
may be removed as a whole when desired.
Having thus described and ascertained the nature of my said Invention,
and the manner of carrying the same into effect, I desire it to be understood
that I claim as my Invention forming the bottoms and the sides of puddling
furnaces of wrought-iron water chambers.
In witness whereof, I, the said George Bedson, have hereunto set my
hand and seal, this Thirteenth day of June, in the year of our Lord
One thousand eight hundred and sixty.
GEORGE BEDSON. (L.S.)
