AN IMPROVEMENT IN POLISHING OR FINISHING YARNS, THREADS, AND WOVEN FABRICS
Year: 1856

page_text: LETTERS PATENT to Charles Brook the younger, of Meltham Mills,
near Huddersfield, in the County of York, for the Invention of "AN
IMPROVEMENT IN POLISHING OR FINISHING YARNS, THREADS, AND WOVEN
FABRICS."
Sealed the 25th November 1856, and dated the 9th September 1856.
PROVISIONAL SPECIFICATION left by the said Charles Brook at the
Office of the Commissioners of Patents, with his Petition, on the
9th September 1856.
I, CHARLES BROOк the younger, of Meltham Mills, near Huddersfield, in
the County of York, do hereby declare the nature of the Invention for "Ax
IMPROVEMENT IN POLISHING OR FINISHING YARNS, THREADS, AND WOVEN FABRICS,"
to be as follows:-
This Invention has for its object an improvement in polishing or finishing
yarns, threads, and woven fabrics. For this purpose the yarns, threads, and
woven fabrics are acted on by the surfaces of rollers caused to move at a high
surface speed, so that the rollers become heated by the friction, and thus

page_text: produce to the yarns, thread, and woven fabric a high polish or finish, superior
to that produced by rollers heated by steam and moving at a less surface
speed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Brook in the Great Seal Patent Office on the 9th
March 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
BROOK the younger, of Meltham Mills, near Huddersfield, in the County of
York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of September, in the year of our
Lord One thousand eight hundred and fifty-six, in the twentieth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Charles Brook, Пer special licence that I, the said Charles
Brook, my executors, administrators, and assigns, or such others as I,
the said Charles Brook, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "AN
IMPROVEMENT IN POLISHING OR FINISHING YARNS, THREADS, AND WOVEN FABRICS,"
upon the condition (amongst others) that I, the said Charles Brook, my
executors or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Charles Brook, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
This Invention has for its object an improvement in polishing or finishing
yarns, threads, and woven fabrics. For this purpose the yarns, threads, and
woven fabrics are acted on by the surfaces of rollers caused to move at a high

page_text: surface speed, so that the rollers become heated by the friction, and thus
produce to the yarns, thread, and woven fabrics a high polish or finish, superior
to that produced by rollers heated by steam, and moving at a less surface
speed.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 shews a side elevation of a machine such as was described in the
Specification of a former Patent granted to me on the 23rd day of February
1856; Figure 2 is a plan thereof, and Figures 3 and 4 are two end views
thereof. In these Figures the same letters of reference are used to indicate
the several parts as were used in the said former Specification, it will not
therefore be necessary to repeat the description thereof in this Specification.
My present improvements, which are applicable to the finishing of yarns and
threads generally which require to be polished, are shown colored, and are
applied near the end of the machine.
A, A, are friction rollers, which I prefer to be of steel or iron, and very
smooth on their rubbing or friction surfaces. It is preferred to employ three
such rollers, but I do not confine myself to the use of that number, as more or
less may be used. These friction rollers are driven at a high velocity, and
produce a better finish than heretofore to the threads or yarns; B, B, are
pulleys on the axes of the polishing or friction rollers A, A, and they receive
motion in a direction opposed to that in which the thread or yarn moves. The
rollers A, A, receive motion by means of the straps G, G, which are actuated
by means of drums or pulleys on the same shaft which drives the beaters u, u.
One of the straps G drives two of the pulleys B, and the other strap G drives
the other pulley B. In place of having all the rollers A plain on their surfaces,
one of them may be grooved with as many grooves as there are threads or
yarns, the grooves corresponding at their lower parts with the diameter of the
thread or yarn. When thus using a grooved friction roller A the reed n may
be dispensed with. When arranging and applying my improvements for the
purpose of polishing and finishing woven fabrics, the machinery shown at
Figures 1, 2, 3, and 4 will remain as shown, except that the reeds and guides
will be dispensed with; and when it is desired that any cloth or fabric shall be
polished or finished only on one side, then the rollers A will be applied to one
side only, and pressing rollers will be used to keep the cloth or fabric to press
against the polishing rollers A.

page_text: Having thus described the nature of my Invention, and the manner of per-
forming the same, I would have it understood that I make no claim to the
mechanical parts separately; but what I claim is, the application of the
combination described with reference to colored parts of the Drawing.
In witness whereof, I, the said Charles Brook, have hereunto set my hand
and seal, this Fifth day of March, in the year of our Lord One thousand
eight hundred and fifty-seven.
Witness,
JNO. ALCOCK.
CHARLES BROOK, JUNE. (L.S.)
