Year: 1823

page_text: ATTWOOD'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
ATTWOOD, of Birmingham, in the County of Warwick, Banker, send greeting.
WHEREAS His most Excellent Majesty King George the Fourth did, by
His Letters Patent under the Great Seal of His United Kingdom, bearing
date at Westminster, the Third day of June 1828, in the fourth year of His
reign, give and grant unto me, the said Thomas Attwood, my exors, admors,
and assigns, His especial licence, full power, sole privilege and authority,
that I, the said Thomas Attwood, my exors, admors, and assigns, during the
term of years therein mentioned, should and lawfully might make, use,
exercise, and vend, within England, Wales, and the Town of Berwick-upon-
Tweed, an Invention communicated to me by a person residing abroad, of
"CERTAIN IMPROVEMENTS IN THE MAKING OF CYLINDERS FOR THE PRINTING OF
COTTONE, CALICOER, AND OTHER ARTICLES;" in which said Letters Patent there
is contained a proviso, that if I, the said Thomas Attwood, shall not particu-
larly describe and ascertain the nature of the said Invention, and in what
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's High Court
of Chancery within six calendar months next and immediately 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, will
more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Thomas Attwood, do hereby declare that the nature of the said Invention,
and the manner in which the same is to be performed, are particularly
described and ascertained in and by the following description thereof (that is
to say):-
The improvements consist in soldering a cylinder of copper or other metal,
or mixture of metals fitted for engraving, upon a cylinder of iron by any of the
nsual well-known methods of soldering which are now in use. I thus obtain
cylinders with an external surface fitted for engraving, and supported by an
internal metal of a cheaper and stronger nature, which enables nearly the whole
of the copper or other metal used for engraving to be turned off without mate-
rially diminishing the strength of the cylinder, and when the whole of the
copper or other metal fitted for engraving is thus turned off or used, the iron
cylinder remains to be recovered from time to time with other cylinders of
_copper, or other metal, as often as may be necessary, at a comparatively trifling:
expence.
In witness whereof, I, the said Thomas Attwood, have hereunto set
my hand and seal, the Twenty-first day of November, in the year of
our Lord One thousand eight hundred and twenty-three.
GEM, Extra.
THOMAS (L.S.) ATTWOOD.
AND BE IT REMEMBERED, that on the Twenty-first day of November,
in the year of our Lord 1823, the aforesaid Thomas Attwood came before our

Inrolled the Twenty-second day of November, in the year of our Lord
One thousand eight hundred and twenty-three.
