IMPROVEMENTS IN PRINTING CALICOES AND OTHER FABRICS
Year: 1839

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MOSES POOLF,
of the Patent Office, Lincoln's Inn, in the County of Middlesex, Gentleman,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Eleventh day of June, in the second year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said Moses
Poole, Her especial licence, full power, sole privilege and authority, that I, the
said Moses Poole, my exors, adiñors, and assigns, or such others as I, the
said Moses Poole, 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, the
Invention of "IMPROVEMENTS IN PRINTING CALICOES AND OTHER FABRICS,"
communicated to me by a certain foreigner residing abroad; in which said
Letters Patent is contained a proviso, that I, the said Moses Poole, shall cause
a particular description of the nature of the said Invention, and in what
manner the same is to be performed, 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
Moses Poole, do declare the nature of the Invention communicated to me is
fully described and ascertained in and by the following description thereof,
reference being had to the Drawing and letters marked thereon (that is
to say)
The Invention consists, first, in a mode of giving elasticity to the cylinders
which communicate the color to the engraved cylinder for printing calico and
other fabrics, by means of elastic material placed between the axis and the
cylinder, as hereafter described.
Secondly, in the construction of a cylinder, the peculiar character of which
is, that one portion of its surface is elastic and the other hard or firm, whereby
I am enabled, in certain cases, to use it either as a presser, or as a means of
communicating the color to the engraved cylinders.
And, thirdly, in a mode of constructing the ordinary wooden cylinders, by
which I obtain a more perfect solidity and fixedness, and in the mode of using
an additional brush, as hereafter described.
In the Drawings I have shewn a front and side view of a printing machine,
and with some of the rollers in detail, but I have only referred to those parts
which relate to the Invention.
Figure 1 represents a cylinder, with its axes passing through the centre,
from end to end, as shewn at A, A; at each end of this axis are two metal
plates B, B, which are fixed to the ends of a tube, made of leather or any
other suitably impermeable material. This tube completely surrounds the
shaft or axis of the cylinder, leaving sufficient space to allow for the introduction
of an elastic material; I prefer to use gum dissolved in water until it comes to
the required glutinous substance, but I do not confine myself thereto, so long
as the material has the property of rendering the cylinder elastic. The elastic
material is put into this tube by an opening at one end of the shaft; the
quantity will depend upon the elasticity required.
Figure 2 represents a cylinder constructed according to the second part of
the Invention, which in certain cases may be used in place of the cylinder
above described. This cylinder is covered with impermeable cloth, in the
ordinary manner; the elasticity is produced by the same means as before
described of Figure 1. It is so constructed that the part marked A remains
fixed. The cylinder is divided into two parts, which are reunited at B; C, the
branch; C forms the axis of a copper or other cylinder, put in movement by
the end pieces D, D, which are turned by the end pieces A; it is upon these
end pieces D, D, that leather or other impermeable material is fixed, which
cover the whole of the cylinder E, F. The wheel-work H, H, is fixed upon

page_text: the end. pieces D, D; when this cylinder is in operation it is placed with the
side marked E against the engraved surface of the cylinder, and the brush
placed against the side marked F; the end pieces A, A, are afterwards fixed
and turned. by means of the end pieces D, D; the distance of the cloth E is
always kept from the iron rod B, whilst the part F is always near the
cylinder C, which offers resistance, and which prevents the pressure on that
part of the elastic cylinder which requires to be very flexible, and it is kept
perfectly firm on one side, which is very essential for certain kinds of work.
The improvement in the construction of the ordinary wooden impression
cylinders consists in a mode of fixing them on a grooved iron axis or shaft, to
which the wooden parts are fixed by sliding them into the dovetailed grooves
and binding them together with copper or other metal bands at each end, as
shewn. Figure 3 shews the grooved iron shaft, also an end view is shewn.
Another improvement, shewn at Figure 4, consists in forming the wooden
printing cylinders of a series of parts, which are laid on the shaft of the
cylinder; the two ends are covered with copper or other metal nuts, which, by
means of screws on the axis, support the ends of the cylinders, and keep them
well bound together.
Figure 5 shews an endless moving brush which works upon a chain, and is
placed in front of the cylinder which supplies the colors to the engraved
cylinder; the object of this brush is, by passing to and fro across the cylinder,
to remove the inequalities or rays left on the surface by the action of the
ordinary brush; it is connected to the sides of the machine by wheel-work,
and put in motion by the turning of the machine.
What I claim as the Invention is, first, the mode of giving elasticity to the
cylinders used in calico and other printing machines, which supply the color to
the engraved cylinder, as herein described.
Secondly, I claim the application to such machinery of a cylinder, onc
portion of which is elastic and the other firm, as herein described.
Thirdly, I claim the mode of constructing wooden cylinders, and the mode
of fixing them, as herein described.
And, lastly, I claim the application of an endless moveable brush, working
with a chain, as shewn and herein described.
In witness whereof, I, the said Moses Poole, have hereunto set my
hand and seal, this Eleventh day of December, in the year of our
Lord One thousand eight hundred and thirty-nine.
MOSES (L.s.) POOLE.
