PROVISIONAL SPECIFICATION.
Improvements in Cop Tubes.
I, ELI JAGGER, of Werneth Metal Factory, Green Street, Werneth, Oldham,
in the County of Lancaster, Tin-plate Worker, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in that class of cop tubes which are used
in spinning for yarn intended to be dyed, bleached, or similarly treated in cop or
other compact form.
To permit of circulating the liquor through the yarn in cop or other compact
form, tubes woven circularly and cut from a continuous length or paper tubes
perforated have heretofore generally been used.
In practice it has been found that the said circularly woven cop tubes do not
permit an easy and free circulation of the liquor through the same and renders it
difficult for placing the tubes onto the spindles of the mules, whilst the paper cop
tube did not allow of a sufficient number of perforations to warrant a uniform
circulation of the liquor through the same and the yarn in cop or other compact
form.
To remedy these defects my invention consists in forming a cop tube of woven
fabric if deemed necessary suitably stiffened the meshes of which are sufficiently
large enough to permit, the required circulation of the liquor. This woven fabric
cop tube I form by hand or machine from a strip of woven fabric of the desired
width and size of meshes by applying paste thereto and wrapping it round the
spindle in the usual manner. On the liquor passing through the yarn in cop or
other compact form, the stiffening or paste in the tube dissolves, thins opening the
meshes of the tube and permitting the liquor to circulate through the same and
the yarn in cop or other compact form in a perfect easy and uniform manner to any
part thereof.

COMPLETE SPECIFICATION.
Improvements in Cop Tubes.
I, ELI JAGGER, of Werneth Metal Factory, Green Street, Werneth, Oldham,
in the County of Lancaster, Tin-plate Worker, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to improvements in that class of cop iubes which are used
in spinning or doubling for the reception of yarn intended to be dyed, bleached, or
similarly treated in cop or other compact form.
To permit of circulating the liquor through the yarn in cop or other compact
form, tubes woven circularly and cut from a continuous length, or perforated paper
tubes have heretofore generally been used.
In practice it has been found that the said circularly woven cop tubes do not
permit an easy and free circulation of the liquor through the same and renders it
difficult for placing the tubes onto the spindles of the mules, whilst the paper cop
tubes did not allow of a sufficient number of perforations to warrant a uniform and
quick circulation of the liquor through the same and the yarn in cop or other
compact form which in some colours is more difficult to attain than in others.

page_text: And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings, in which―
Figs. 1 & 3 are perspective views of cop tubes made according to my invention.
Fig. 2 represents a cut piece and Fig. 4 a strip of fabric from which the said cop
tubes are made respectively.
In carrying out my invention, the improvements consist in forming cop tubes,
such as shown in Figs. 1 & 3 of woven fabric, suitably stiffened or finished, the
meshes of which are sufficiently large enough to permit the required circulation of
the liquor. These woven fabric cop tubes, I form by hand out of suitably shaped
pieces, such as shown in Fig. 2, or by an ordinary cop tube making machine, from
a strip of woven fabric, such as shown in Fig. 4, of the desired width and size of
meshes, by applying paste thereto and rolling or wrapping it round a spindle in the
usual manner. The dotted lines in Fig. 4 represent the cut of the knife through
the said strip. On the liquor passing through the yarn in cop or other compact
form, the stiffening or paste in the tube dissolves, thus opening the meshes of the
tube and permitting the liquor to circulate through the same and the yarn in a
perfect easy and uniform manner, to any part thereof.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is-
A tube for the reception of yarn used in spinning or doubling, consisting of a
piece or strip of woven fabric, suitably meshed, stiffened or finished and rolled or
wrapped into tube form, by any suitable means, substantially as and for the purpose
set forth.
