Year: 1850

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME. I, GEORGE
ATTWOOD, of Birmingham, in the County of Warwick, Copper Roller Manu-
facturer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by
Her Royal Letters under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Fifteenth day of April,
One thousand eight hundred and fifty, in the thirteenth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said George
Attwood, my exors, admors, and assigns, Her especial license, full power,
sole privilege and authority, that I, the said George Attwood, my exors,
adñors, and assigns, or such others as I, the said George Attwood, my
exors, adñors, or assigns, should at any time agree with, and no others,
from time to time and at all times 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 Invention of "A NEW OR
IMPROVED METHOD OF MAKING TUBING OF COPPER OR. ALLOYS OP COPPER;" in which
said Letters Patent is contained a proviso, that I, the said George Attwood,
shall cause a particular description of the nature of my said Invention, and in
what manner the same is to be performed, by an instrument in writing under
my hand and seal, to be inrolled in Her said Majesty's High Court of Chancery
within six calendar months next and immediately after the date of the said in
part recited Letters Patent, as in and by the same, reference 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
George Attwood, do hereby declare that the nature of my said Invention, and
in what manner the same is to be performed, are fully described and ascertained
in and by the following description thereof, that is to say:
My Invention of a new or improved method of making tubing of copper,
or alloys of copper, consists in using for the purpose of making it such hollow
copper rollers, or such rollers as are commonly called copper rollers, and as
are made and used for printing or otherwise operating upon woven or textile
goods or fabrics of cotton, silk, linen, and wool, or of a mixture of any of them,
or of any other animal or vegetable materials, or upon paper or leather, and in
using such of the said rollers only as are made without soldering or braizing,
after they have been used for the purposes for which they were originally
made and intended; and when worn out, done with, or no longer wanted for
such purposes, I then first remove from them any nibs or slots, if there are
any, or such parts of the said nibs or slots, as it may be desirable to remove,
as have been placed or formed in their interiors for the purpose of holding
them firm upon the iron or other mandrills or axes when at work or in use.
This I effect by such lathes as are well known to and in use among copper
rollers makers and others, or by some other suitable means; I then roll the
rollers down between iron rolls properly grooved for the purpose, or draw
them down in draw benches into tubing upon suitable iron or steel mandrills
in the way they are originally made, and in the way also in which braized or
soldered copper or brass tubing is commonly drawn in draw benches. In one
or other of these ways I operate upon the said rollers until they become of
the lengths, diameters, and thinness of metal required for the different sizes
and sorts of tubing; but the grooves of the iron rolls and the iron or steel
mandrills and other tools I use for these purposes, are, as occasion requires,
of different sizes and dimensions from those with which the copper or alloyed
rollers were originally made.
I anneal the rollers from time to time as often as experience recommends
during the process of. drawing or rolling them down into tubing, and some-
times I roll or draw them down more or less at a red heat. By these means
I form the copper or alloyed rollers into tubing of the lengths, diameters, and
thinness of metal most suitable for use in the boilers and other parts of steam-
engines, in breweries and distilleries, for gas fitting, upholstery, sugar works,
and other purposes where such tubing is required. The copper, which is used
for making copper rollers, may be commonly alloyed with small portions of
some other metal or metals, but the rollers made of such alloyed copper are
nevertheless commonly called copper rollers; and I claim the exclusive use of

page_text: such rollers for the purpose of making tubing as are usually known as, and
commonly called, "copper rollers" in Lancashire and other places, where they
are made and used for printing and otherwise operating upon cotton and other
textile or woven goods or fabrics, and upon paper or leather, and which have
been used for one or other of these purposes, and which are worn out or done
with, or are no longer wanted for the said purposes. And I claim the
exclusive use of such old, worn out, done with, or no longer wanted copper
rollers, as aforesaid, for the purpose of being elongated, contracted, or extended
for the purpose of making the kinds of tubing, as aforesaid.
In witness whereof, I, the said George Attwood, have hereunto set my
hand and seal, this Twelfth day of September, in the year of our Lord
One thousand eight hundred and fifty.
