Year: 1847

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
COATES, of Seedly, in the County of Lancaster, Calico Printer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-seventh day of April, in the tenth year of Her
reign, and in the year of our Lord One thousand eight hundred and forty-
seven, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Coates, Her especial license, full power, sole privilege
and authority, that I, the said John Coates, my executors, administrators,
and assigns, and such others as I, the said John Coates, my executors,
administrators, 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 ex-
pressed, should and lawfully might make, use, exercise, and vend, within
England and Wales and the Town of Berwick-upon-Tweed, my Inven-
tion of "CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR CLEANING
THE SURFACE OF WOVEN FABRICS, OR FREEING THE SAME FROM FIBROUS OR OTHER
LOOSE MATTERS PREVIOUS TO PRINTING THEREON;" in which said Letters Patent
is contained a proviso that I, the said John Coates, shall cause a particular
description of the nature of my said Invention, and in what manner the same
is to be performed, to be enrolled in Her 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.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Coates, do hereby declare that the nature of
nature of my said Invention,

page_text: and in what manner the same is to be performed, is particularly described and
ascertained in and by the Drawings hereto annexed, and the following
explanation thereof (that is to say):-
=
These improvements in machinery or apparatus for cleaning the surface of
woven fabrics, or freeing the same from fibrous or other loose matters, consist
in the application, employment, or use for such purposes of a revolving
cylinder or roller covered with wire cards (such as is used in the carding
of cotton), either employed in connection with a stationary brush or without it,
which apparatus may be either attached to the ordinary printing machine for
printing calicoes or other woven fabrics, or to the winding machine for pre-
paring the cloth roller used in such machinery, or used separately from either.
This apparatus is to be applied to the surface of calico, or any woven fabric,
to clean it from loose fibres or other extraneous matters, previous to printing
thereon, and thereby preventing the occurrence of imperfect work frequently
arising from the presence of such loose matters, and also increasing the
capability of producing more work in a given time. Such card cylinder, or
roller and brush, or any other modification of a similar cleaning apparatus,
may either be used separately or detached, if preferred, or may be attached to
or in connection with the ordinary calico printing machine, as herein described,
and placed between the cloth roller and the printing roller, or it be
employed in any other convenient situation.

In the Drawing accompanying these Presents, Figure 1 shews a plan view
of an arrangement of mechanism which is suitable to the above purposes, and
drawn upon a scale of about two inches to the foot; Figure 2 is an end view,
and Figure 8 a section of the same. Figure 4 is a diagram shewing the
relative position of the apparatus when used in connection with the ordinary
calico-printing machine. The cloth or calico is represented by the red lino.
a, a, is the side framing of the apparatus connected together by the rods b, b, and
supporting the tension rail c, c, under which the cloth passes, and thence over
the stationary brush d, d, which has a "doctor," or steel blade e, e, extending
along one side. The cloth then passes over the wire card cylinder or roller
f, f, and over the tension roller g, g, to the printing apparatus. The roller g, g,
may be covered with felt or cloth, if preferred, and the tension of the calico or
other woven fabric passing over it, causes the same to revolve, and, by means
of the spur pinion h and wheel i, turns the wire card cylinder or roller f. f
in the reverse direction. Thus the calico or other woven fabric passing under
the stationary brush d, d, and doctor e, e, and subsequently over the revolving
card cylinder or roller, becomes thoroughly brushed and cleaned from any loose
material which might adhere to it, thus causing the fabric to present a much

page_text: smoother or better surface for printing. The brush d, d, and the wire card
cylinder or roller f, f, may be adjusted by the screws k, k, and a slight lateral
or traversing motion may also be imparted to it, perhaps in some instances
with good effect, or it may also be placed in other instances, in an oblique
direction to that of the cloth. When the apparatus is not desired to be at
work, the tension rail c, c, may be thrown into the position shewn by dotted
lines at Figure 3, by means of the lever ; the cloth will then pass over the
roller g, g, without touching the brush or the said card cylinder or roller.
In witness whereof, I, the said John Coates, have hereunto set my
hand and seal, this Thirty-first day of July, One thousand cight
hundred and forty-seven.
