page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN
Cook, of Birmingham, in the County of Warwick, Brassfounder, send greeting.
WHEREAS His most Excellent Majesty King George the Fourth, by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-third day of April, in the tenth year of His reign, did,
for Himself, His heirs and successors, give and grant unto me, the said
Benjamin Cook, my executors, administrators, and assigns, His special licence,
full power, sole privilege and authority, that I, the said Benjamin Cook, my
executors, administrators, and assigns, and every of them, by himself and
themselves, or by his and their deputy or deputies, servants or agents, or such
others as I, the said Benjamin Cook, my executors, administrators, or assigns,
should at any time agree with, and no others, from time to time and at all
times thereafter during the term of years therein expressed, should and lawfully.
might make, use, exercise, and vend, within that part of the United Kingdom
called England, the Dominion of Wales, and Town of Berwick-upon-Tweed,
my Invention of "AN IMPROVED METHOD OF MAKING ROLLERS OR CYLINDERS OF
COPPER AND OTHER METALS, OR A MIXTURE OF METALS, FOR PRINTING OF CALICOS,
SILKS, CLOTHS, AND OTHER ARTICLES;" in which said Letters Patent there is
contained a proviso, obliging me, the said Benjamin Cook, by an instrument
in writing under my hand and seal, particularly to describe and ascertain
the nature of my said Invention, and in what manner the same is to be
performed, and to cause the same to be inrolled in His Majesty's High Court
of Chancery within six calendar months next and immediately after the

page_text: date of the said recited Letters-Patent, as in and-by-the-same, reference.being
thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Benjamin Cook, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, is described and
ascertained in the following explanation thereof (that is to say):―
First, in the novel-form-I-give-to-the-mandrel-or-axle on which the cylinder
or outer shell of copper or other metal or alloy is, mounted; and, secondly, in
the internal form or shape of the copper or other external shell, and the way
or method employed for so forming it. Instead of making the mandrels or
axles of my improved printing rollers circular, that is, of a cylindrical form and
slightly conical, which is as they have been heretofore made, now shape the
mandrels elliptical, or otherwise eccentric, or cylindrically, rose shaped, and
slightly tapered or conical, which may be done by turning them in an oval or
an eccentric lathe, or any other lathe, or by any other convenient means, and
having prepared cylindrical ingots of copper, brass, or other proper alloys of
suitable lengths-and-diameters, a cylindrical hole being bored, Idrilled, or
otherwise, formed through the axis of each ingots leavingan small-shoulder.cor
inwardly-projecting ring at one end, to act as alstoplagainst the mandrel when
drawing the ingot-down- orishaping it to the form and size required lathen
introduce the mandrel into the hollow ingot which is to form its shell and
place them in a draw bench or other suitable machine, and draw the external
surface of the shell perfectly-cylindrical through holess or draw plates to the
dimensions-Ifwish, which causes the shell to form itself internally-elliptical for
eccentric and.to.the exact figure of the mandreland when so fitted and turned
truly "cylindrical-and-polished on the outer surfaces constitutes my improved
printing roller. The mandrelson which the copperpof other (shell has been
drawn, as above, described, may have journies tumed on it and be employed
as its working-axle in-the-printing-press; but if not so used all the axles.or
mandrels must be formed exactly to the sameifigure and dimensions, as the
original mandrel, in order that any number of external shells may fit in.common
upon them for changing-the patterns. The designs or subjects: employed for
printing are of course engraved on the polished surface of the external-shells-in
the same manner as-is-now-usually adopted in printing calicos, silks, cloths;
and other articles.--Lastly, Ido hereby declare that my improved method of
making rollers or cylinders of copper and other metals/oria mixture of metals for
printing calicos, silks, cloths, and other articles consists in the above-described
employment of elliptical-mandrels.or eccentric axles on which the copperior
other shells are formed and fitted-as aforesaid, and in the means employed in

page_text: fitting exactly the inside of the ingots of copper, brass, or other alloy to the
mandrel, as above described.
In witness whereof, I, the said Benjamin Cook, have hereunto set my
hand and seal, the Nineteenth day of September, One thousand eight
hundred and twenty-nine.
AND BE IT REMEMBERED, that on the same Nineteenth day of
September, in the year above mentioned, the aforesaid Benjamin Cook
came before our Lord the King in His Chancery, and acknowledged the
Specification aforesaid, and all and every thing therein contained, in form
above written. And also the Specification aforesaid was stamped according
to the tenor of the Statute in that case made and provided.
Inrolled the Twenty-first day of September, in the year above written.
