page_text: OSBORN'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME,
HENRY OSBORN, of Bordesley, near Birmingham, in the County of
Warwick, Sword and Gun Barrel Maker, send greeting.
WHEREAS His most Excellent Majesty King George the Third,
by His Letters Patent under the Great Seal of Great Britain, bearing
date at Westminster, the Twenty-eighth day of November, in the fifty-
third year of His reign, did give and grant: unto me; the said Henry
Osborn, my exors, admors, and assigns, His special licence, full power,
sole privilege and authority, that I, the said Henry Osborn, my exors,
admors, and assigns, 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 new Invention of
WELDING, AND MAKING. OF VARIOUS KINDS OF CYLINDER OF IRON AND
STEEL;" in which Letters Patent there is contained a proviso, obliging:
me, the said Henry Osborn, under my hand and seal, to cause a particular
description of the.nature, of my said Invention, and in what manner the
same is to be performed, to be inrolled in. His Majesty's High Court of
Chancery within two calendar months next and immediately after the

page_text: date of the said recited Letters Patent, as in and by the same, relation
being thereto had, may more fully and at large appear.
NOW KNOW YE, that I, the said Henry Osborn, in compliance and
performance of the proviso contained in the said Letters Patent, do
hereby declare that my said Invention dotli, by this instrument in writing
under my hand and seal, particularly describe and ascertain the nature
of my said Invention, and the manner in which the same is to be per-
formed, as well by a description.in. writing, as also by a delineation of
apparatus hereunto annexed, that will help to illustrate or exemplify my
said principle (that is to say):
I. take a turned skelp (for which I have previously obtained His
Majesty's Royal Letters Patent) for a gun or pistol barrel of any
description, or any other cylindrical article, and bring it to a welding
heat in an open or close fire, as may best suit my purpose, and when
in a welding state I put a mandrill in the inside, and place the skelp
or cylinder so prepared in the swage Number 1, machine A, and by a
regular rotative motion of the cam ring Number 3, such speed is given
to the hammer Number 2, as completely effects the welding. The dif-
ferent groves in the swage Number 1, is to assist in gathering the different
parts of the barrel or cylinder in the process of welding; or to effect the
welding by means of machine B, I take a turned patent skelp, or other
cylindrical article prepared as herein-before described, and placed in
either of the beds Number 3, 4, or 5, according to the part required to
be welded, and which welding is effected by the segment performing half
a revolution, the manner of which is explained by profile Number 10.
And, lastly, the fixed framework for supporting my said machinery, and
the manner of connecting the several parts together, so that their motions.
may be properly adapted to the purposes herein-before described, in order
to shew the nature of my said Invention, and the means by which the
same is to be carried into effect, together with the methods of driving
the said machinery by any of the powers usually employed to give
motion to machines; and also the several materials to be used in con-
structing the same, may be made, used, adapted, and applied in different
manners, according to the choice or judgment of the maker; and any
workman of competent skill in the construction of mill work or the like

page_text: machinery will find no difficulty in forming, making, and completeing
the same from the general instructions here given.
In witness whereof, I, the said Henry Osborn, have to this Specifi-
cation set my hand and seal, the Twenty-sixth day of January,
One thousand eight hundred and thirteen.
