IMPROVEMENTS IN MACHINERY OR APPARATUS FOR APPLYING SIZE AND COLOUR TO YARNS OR THREADS
Year: 1875

page_text: LETTERS PATENT to Robert Fergusson, of the City of Manchester,
Thread Manufacturer, for the Invention of "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR APPLYING SIZE AND COLOUR TO YARNS OR
THREADS."
Sealed the 11th January 1876, and dated the 28th September 1875.
PROVISIONAL SPECIFICATION left by the said Robert Fergusson at
the Office of the Commissioners of Patents, with his Petition, on
the 28th September 1875.
I, ROBERT FERGUSSON, of the City of Manchester, Thread Manu-
facturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR APPLYING SIZE AND COLOUR
TO YARNS OR THREADS," to be as follows :—
My Invention is applicable to the ordinary machines now in use for
polishing and finishing yarns or threads, and it consists in applying the
size or colouring matter to the banks of yarns or threads when distended
on the ordinary stretching rollers by means of a roller or brush revolving
in a trough containing the size or colouring matter; or the size or

page_text: colouring matter may be supplied to the revolving roller, which deposits
it on the yarns or threads.
The revolving roller is supported in weighted levers or other
equivalents, which give the requisite pressure against the yarns or
threads, and the roller is moved out of contact with the yarns or threads
when the desired quantity of size or colour has becu applied.
The polishing is performed in the ordinary manner.
nied by the said Kobert Fergusson in the Great Deal Inte
Office on the 25th March 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
FERGUSSON, of the City of Manchester, Thread Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of September, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Robert Fergusson, Her
special licence that I, the said Robert Fergusson, my executors,
administrators, and assigns, or such others as I, the said Robert
Fergusson, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 "IMPROVEMENTS IN MACHINERY OR APParatus for APPLYING SIZE ANd Colour
TO YARNS OR THREADS," upon the condition (amongst others) that I, the said
Robert Fergusson, 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.

page_text: NOW KNOW YE, that I, the said Robert Fergusson, do hereby
declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in
and by the following statement (that is to say) :-
My Invention is applicable to the ordinary machines now in use for
polishing and finishing yarns or threads, and it consists in applying the
size or colouring matter to the hanks of yarns or threads when distended
on the ordinary stretching rollers by means of a roller or brush revolving
in a trough containing the size or colouring matter; or the size or
colouring matter may be supplied to the revolving roller, which deposits
it on the yarns or threads.
The revolving roller is supported in weighted or other levers or other
equivalents, which give the requisito pressure against the yarns or
threads, and the roller is moved out of contact with the yarns or threads
when the desired quantity of size or colour has been applied.
The polishing is performed in the ordinary manner.
And in order that my Invention may be fully understood I will
proceed to describe the accompanying Sheet of Drawings, in which
Fig. 1 is an end view, and Fig. 2 a front view of an ordinary machino
for polishing and finishing yarn or thread, to which my improvements
are applied.
a is the framing; b, b, the polishing rollers; c, the swing frame;
d, the top stretching roller; and e, the bottom stretching roller, between
which the hanks of yarn or thread are distended; these parts and the
gearing for raising or lowering the bottom roller e are made as usual.
My improvement consists in the apparatus for applying size or
colouring matter to the hanks of yarn or thread as they are passing
around the distending rollers d and e. The trough ƒ containing the size
or colouring matter is fixed on the frames a above the top polishing
roller b, or in any other convenient position; to this trough are fixed
the fulcrum studs for the levers g, in which the roller or brush h revolves;
this roller or brush bears upon and is turned round by the banks of yarn
or thread passing around the stretching rollers & and e, and the pressure
of the roller or brush can be varied by weights connected to the
lovers or otherwise. The size or colour is taken from the trough ƒ and

page_text: delivered to the roller or brush & by the small roller i, the lower part of
which is immersed in the size or colour.
When the desired quantity of size or colour has been applied the
roller or brush is moved out of contact with the yarn or thread, and
the polishing is performed in the ordinary manner.
My Invention may be modified by placing the trough fand the roller
or brush / under the top stretching roller d, as shewn in dotted lines in
Fig. 1; in this arrangement the trough bears upon eccentrics on the
cross shaft j, and when the desired quantity of size or colour has been
applied to the stretching roller d, and by it to the hanks of yarn or
thread the shaft j is turned partly round to remove the roller or brush h
out of contact with the under side of the roller d.
Having thus stated the nature of my Invention, and described two
convenient ways of performing the same, I wish to remark that I do
not limit myself to the details given, as they must be varied according
to the peculiar construction of the polishing machine to which theso
improvements are applied; I claim, the roller or brush and parts
acting in combination therewith for applying size or colour to the hanks
of yarn or thread to be polished, or to one of the rollers around which
the hanks are passing, as shewn and described.
In witness whereof, I, the said Robert Fergusson, have hereto
set my hand and scal, this Twenty-fourth day of March, Onc
thousand cight hundred and soventy-six.
