IMPROVEMENTS IN YARN HOLDERS
Year: 1870

page_text: LETTERS PATENT to James Milton, Manager to Messieurs. John
Sommerville and Sons, Manufacturers, of Glasgow, in the County
of Lanark, North Britain, for the Invention of "IMPROVEMENTS IN
YARN HOLDERS."
Sealed the 18th October 1870, and dated the 21st April 1870..
PROVISIONAL SPECIFICATION left by the said James Milton at the
Office of the Commissioners of Patents, with his Petition, on the
21st April 1870.
I, JAMES MILTON, Manager to Messieurs John Sommerville and Sons,
Manufacturers, of Glasgow, in the County of Lanark, North Britain, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
YARN HOLDERS," to be as follows, that is to say :—
This Invention has for its. objects to prevent the waste of yarn which
ordinarily takes place when the yarn is in the cop form, and to admit of
the yarn being bleached, dyed, and otherwise dealt with in the cop form
in a uniform manner and without risk of damage.
The improved holder consists of a tubular spindle or sheath made of
thin brass or other suitable metal. It is of a tapered form adapted for

page_text: fitting upon the spindle of the spinning mule or machine, and is
strengthened by a flange or collar at its thicker end. It is made
sufficiently long to receive the entire cop in the spinning process, and
the cop is removed upon it from the spindle, and when used as weft is
kept upon it until it is unwound in the process of weaving, being pre-
vented from slipping off by one or more slightly raised collars which
are formed upon it, and which also strengthen it. The holder is made
open at both ends, and is formed with one or more longitudinal
slots or openings, and when the cops are being bleached or dyed the
liquids used have access through these slots and through the hollow
spindle to the core of the cop, so as to ensure complete saturation and
uniform action throughout the thickness of the cop.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Milton in the Great Seal Patent Office on
the 20th October 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
MILTON, Manager to Messieurs John Sommerville and Sons, Manufac-
turers, of Glasgow, in the County of Lanark, North Britain, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of April, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said James Milton, Her special licence that
I, the said James Milton, my executors, administrators, and assigns, or
such others as I, the said James Milton, 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 "IMPROVEMENTS IN YARN HOLDERS,"
upon the condition (amongst others) that I, the said James Milton,
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

page_text: manner the same was to be performed, and cause the same to be filed
in the Great Scal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said James Milton, 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 in writing, reference being had to the accompanying
Drawings, that is to say :-
My said Invention has for its objects to prevent the waste of yarn
which ordinarily takes place when the yarn is in the cop form, and to
admit of the yarn being bleached, dyed, and otherwise dealt with in
the cop form in a uniform manner and without risk of damage.
My improved holder consists of a tubular spindle or sheath of thin or
light metal of a tapered form, and made hollow, and with slots and
perforations so that bleaching, dyeing, or other liquids may have access
to the core of the cop, and so as to ensure complete saturation and
uniform action throughout the thickness of the cop.
And in order that my said Invention, and the manner of performing
the same may be properly understood, I have hereunto appended a
Sheet of explanatory Drawings to be herein-after referred to and
representing by way of example a modification as made according to my
Invention.
Figure 1 is a vertical section showing the yarn holder with the cop
of yarn (colored blue) upon it; Figures 2 and 3 are elevations showing
opposite sides of the yarn holder, whilst Figure 4 is an elevation of the
form of spindle to suit which the yarn holder shown in Figures 1, 2,
and 3 is made.
The holder is a tapered tube 1, 2, of thin brass or other suitable
metal not easily acted upon by the liquids used in bleaching, dyeing, or
otherwise treating or preparing the yarn.
The holder 1, 2, is open at
both ends and is shaped to fit firmly upon the spindle (Figure 4) of the
spinning mule or other machine, and is strengthened by a flange or
collar 3 at its thicker end. One or more longitudinal slits or openings 4
are formed in the holder, which formation allows the sides to spring a
little, and they do so in being put upon the spindle, and in consequence
exert a gripping pressure on the spindle which keeps the holder firmly
in its place. The spindle figure 4 is not formed with a square collar as

page_text: a stop for the collar 3 of the holder when putting it on, but with a
slight enlargement or shoulder 5, and the interior of the holder is
formed with a corresponding slight enlargement 6. This arrangement
renders it more convenient when removing a full cop and its holder
for engaging the yarn end, first with the spindle, and subsequently with
the fresh holder, whereas a projecting square collar on the spindle
would render those operations more difficult. The slots 4 besides
rendering the sides of the holder elastic as herein-before indicated also
serve to give free access for bleaching or other liquids to enter by the
ends of the holder and reach the core or internal parts of the cop, and
perforations are also formed in the sheath or sides of the holder to
give additional-access for the permeation of liquids. The holder is made
sufficiently long to receive the entire cop in the spinning process, and
the cop is removed upon it from the spindle, and when used as weft is
kept upon it until it is unwound in the process of weaving, being
prevented from slipping off by one or more slightly raised collars 7,
which are formed upon it, and which also strengthen it.
Having thus particularly described my said Invention, and the
manner in which the same is to be performed, I have to state that what
I believe to be novel and original and claim as the Invention secured to
me by the herein-before in part recited Letters Patent is, the con-
structing and adapting of yarn holders in the improved manner
substantially as herein-before described, and the bleaching and dyeing of
yarn in the cop form by the aid of improved holders, substantially such
as are herein-before described.
In witness whereof, I, the said James Milton, have hereunto set my
hand and seal, this Nineteenth day of October, in the year of
our Lord One thousand eight hundred and seventy.
Witness,
EDMUND HUNT,
Patent Agent,
Glasgow.
