A NEW OR IMPROVED MACHINE FOR TURNING AND LEVELING VARIOUS ARTICLES MADE OF IRON, PREPARATORY TO WELDING AND GRINDING
Year: 1812

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
HENRY OSBORN, of Bordesley, near Birmingham, in the County of
Warwick, send greeting.
WHEREAS His most Excellent Majesty King George the Third
did, His Letters Patent under the Great Seal of the United King-
dom of Great Britain and Ireland, bearing date at Westminster, the
Third day of August, in the fifty-second year of His reign, give and
grant unto me, the said Henry Osborn, my exors, adñiors, and assigns,
His especial license, full power, sole privilege and authority, that I,
the said Henry Osborn, my exors, admors, and assigns, should and
lawfully might, during the term of years therein mentioned, make, 'use,
exercise, and vend, within England, Wales, and the Town of Berwick
upon Tweed, my Invention of "A NEW OR IMPROVED MACHINE FOR
TURNING AND LEVELING VARIOUS ARTICLES MADE OF IRON, PREPARATORY TO
WELDING AND GRINDING," in which said Letters Patent there is contained
a proviso, that if I, the said Henry Osborn, shall not particularly
describe and ascertain the nature of my said Invention, and in what

page_text: manner the same is to be performed, by an instrument in writing under
my hand and seal, and cause the same to be inrolled in His Majesty'
High Court of Chancery within two calendar months next and immie-
diately after the date of the said Letters Patent, that then the said
Letters Patent, and all liberties and advantages whatsoever thereby
granted, shall utterly cease, determine, and become void, as in and by
the same (relation being thereunto had) may more fully and at large
appear.
NOW KNOW YE, that in compliance with the said proviso, I, the
said Henry Osborn, do hereby declare that the application of my said
Invention is as follows:-
First, the machine being completed according to the Drawing and
references hereunto annexed, I take skelps of the sorts that are usually
used, and instead of partially heating them in a welding or smith's fire,
I heat them completely from end to end in a reverbatory furnace;
when properly heated and the machine in motion, I pass the skelp
under the segment C, by which means it becomes hollow its whole
length I then pass it under the segment D, which gathers the sides
up close together and makes the hollow much deeper. Lastly, I pass it
under the segment E, with the two edges 'downwards in the V form of
the swage H, and the back or round part in the hollow of the seg-
ment E; this finishes the operation, and the skelp becomes closed from
end to end and fit to be welded. The advantages to be derived from
this machine is, that it renders the skelps perfectly straight and smooth
from end to end, and does not disturb the grain of the iron as is usually
the case with skelps turned in the common way with the panes of
sledge hammers. It is also applicable with great advantage to a
variety of other purposes, in the manufacture of fire-arms and other
articles..
In witness whereof, I, the said Henry Osborn, have hereunto set
my hand and seal, this First day of October, in the year of our
Lord One thousand eight hundred and twelve.
HENRY OSBORN. (L.S.)
