IMPROVEMENTS IN TREATING YARNS WHEN WOUND INTO COPS OR ANALOGOUS FORMS FOR USE IN SEWING MACHINES
Year: 1875

page_text: LETTERS PATENT to William Cox, of Lochec, in the County of Forfar,
North Britain, Manufacturer, for the Invention of "IMPROVEMENTS IN
TREATING YARNS WHEN WOUND INTO COPS OR ANALOGOUS FORMS FOR USE IN
SEWING MACHINES."
Sealed the 25th June 1875, and dated the 22nd April 1875.
PROVISIONAL SPECIFICATION left by the said William Cox at the
Office of the Commissioners of Patents, with his Petition, on the
22nd April 1875.
I, WILLIAM Cox, of Lochee, in the County of Forfar, North Britain,
Manufacturer, do hereby declare the nature of the said Invention of
"IMPROVEMENTS IN TREATING YARNS WHEN WOUND INTO COPS OR ANALOGOUS FORMS
FOR USE IN SEWING MACHINES," to be as follows, that is to say:-
This Invention, which relates to improvements in treating yarns when
wound into cops or on tubes, pirns, or other holders for use in the
shuttles or equivalent carriers of sewing machines, has for its object to
diminish as much as possible the length and diameter of the body of

page_text: yarn when so used, whilst enabling the same quantity of yarn to be
employed as with the cops or other forms of the dimensions at present
employed.
The Invention is applicable to yarns of all kinds, including cotton and
silk as well as flax, hemp, jute, and others analogous thereto, and it i
enables shuttles or equivalent carriers of less length and diameter than
those at present used to be employed in the shuttle race or the equivalent
thereof in sewing machines.
The Invention consists in subjecting the cops or other forms into
which the yarn is wound to considerable pressure in moulds or dies of
the form and dimensions into which it is desired to compress the same,
the pressure used being sufficient to cause the cops or other forms into
which the yarn has been wound to retain the dimensions and form into
which it is compressed by hydraulic, steam, or other power.
By using two or more cops or other forms of yarn compressed in the 1
manner described twice, thrice, or more times the quantity of yarn can
be placed in the sewing machine shuttle or equivalent carrier than is the
case under the present mode of working.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Cox in the Great Seal Patent Office on 2
the 21st October 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
Cox, of Lochee, in the County of Forfar, North Britain, Manufacturer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters 2
Patent, bearing date the Twenty-second day of April, in the year of our
Lord One thousand eight hundred and seventy-five, in the 38th year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said William Cox, Her special license that I, the said
William Cox, my executors, administrators, and assigns, or such others 3
as I, the said William Cox, my executors, administrators, or 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

page_text: Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN TREATING YARNS WHEN WOUND
INTO COPS OR ANALOGOUS FORMS FOR USE IN SEWING MACHINES," upon the con-
dition (amongst others) that I, the said William Cox, by an instrument
in writing under my hand and seal, 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 William Cox, 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 said Invention, which relates to improvements in treating yarns
when wound into cops, or on tubes, pirns, or other holders for use in the
shuttles or equivalent carriers of sewing machines, has for its object to
diminish as much as possible the length and diameter of the body of
yarn when so used, whilst enabling the same quantity of yarn to be
employed as with the cops or other forms of yarn when wound of the
dimensions at present in use.
The Invention is an extension or further application of that for which
Letters Patent were granted to me, the said William Cox, dated the
Twenty-second day of February, A.D. 1875, and numbered 642.
The Invention is applicable to yarns of all kinds, including cotton and
silk, as well as flax, hemp, jute, and others analogous thereto, and it
enables shuttles or equivalent carriers of less length and diameter than
those at present used to be employed in the shuttle race or the equivalent
thereof in sewing machines.
The Invention consists in subjecting the cops or other forms into
which the yarn is wound to considerable pressure in moulds or dies of
the form and dimensions into which it is desired to compress the same,
the pressure used being sufficient to cause the cops or other forms into
which the yarn has been wound to retain the dimensions and form into
which it is compressed by hydraulic, steam, or other power.
By using two or more cops or other forms of yarn compressed in the
manner described, twice, thrice, or more times the quantity of yarn can

page_text: be placed in the sewing machine shuttle or equivalent carrier than is the
case under the present mode of working.
The mechanism by which the compression of the cops is effected may
be like that set forth in the Specification and Drawings filed in pursuance
of the aforesaid Letters Patent, No. 642, A.D. 1875; or other analogous
mechanism may be adopted.
Having now described and particularly ascertained the nature of my
said Invention, and the system, mode, or manner in or under which the
same is or may be used or practically carried into effect, I would observe
in conclusion that what I consider to be novel and original, and there-
fore claim as the Invention secured to me by the herein-before in part
recited Letters Patent is, diminishing the size of cops or other forms into
which the yarn used in the shuttles or equivalent carriers of sewing
machines is wound, by subjecting the same to pressure in moulds or dies
of the required shape.
In witness whereof, I, the said William Cox, have hereunto set
my hand and seal, this Nineteenth day of October, One thousand
cight hundred and seventy-five.
