PROVISIONAL SPECIFICATION.
Improvements in Paper Cop Tubes and Machines for the
Manufacture of the same.
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 paper cop tubes and
machines for the manufacture of the same which are used for yarn intended to be
dyed, bleached, or similarly treated in cop form.
In order to permit of the dye or other liquor passing freely through the paper
cop tube, the latter has been formed with perforations, either by hand or machine,
after having been wound. The means heretofore employed for this purpose,
flattened the tube, therefore necessitating the opening of it, so as to some extent
permit of placing it onto the spindle, which operation is not only expensive and
troublesome but also spoils the appearance and shape of the cop tube and renders
the placing of it onto the spindle more difficult than if the cop tube had been
retained in its original shape and not been flattened.
To remedy these defects my invention consists in providing a cop tube which
consists of paper suitably perforated previously to being wound to the shape, and
in employing a suitable punching apparatus in the cop tube machine itself, so as to
perforate the strip of paper from which the cop tube is made, either before or after
the paste has been applied thereto and thus form the perforations in the paper cop
tube whilst it is being formed, thereby retaining its proper shape and avoiding the
necessity of a second operation and opening of the paper cop tube.
The said punching apparatus may consist of a frame secured on the bed plate of
the cop tube machine, between the paste rollers and feed rollers and containing a
number of punches operating in conjunction with a corresponding die over which
the strip of paper, from which the cop tube is made, passes. The said punches
may be actuated by means of a cam, eccentric, screw, lever, or otherwise, as most
convenient from any moving part of the cop tube machine by the aid of suitable
gearing and levers."
The holes in the die and the punches are so positioned in relation to each other,
that on the previously perforated strip of paper being wrapped round the spindle of
the cop tube machine once, the perforations of the second wrap will meet those of
the first wrap, or vice versa, and thus come opposite to each other, so as to form a
clear passage for the dye or other liquor.

COMPLETE SPECIFICATION.
Improvements in Paper Cop Tubes and Machines for the
Manufacture of the same.
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 paper cop tubes and
machines for the manufacture of the same which are used in spinning, doubling and

page_text: the like operations for the reception of yarn intended to be dyed, bleached, or
similarly treated in cop form.
In order to permit of the dye or other liquor passing freely through the paper
cop tube, the latter has been formed with perforations, either by hand or machine
after having been wound or rolled. The means heretofore employed for this
purpose, flattened the tube, therefore necessitating the opening of it so as, to some
extent, permit of placing it onto the spindle, which operation is not only expensive
and troublesome, but also spoils the appearance and shape of the cop tube and
renders the placing of it onto the spindle more difficult than if the cop tube had
been retained in its original shape and not been flattened.
To remedy these defects my invention consists, in providing a cop tube which
consists of paper suitably perforated previously to being wound or rolled into tube
shape and in employing a suitable punching apparatus in the cop making tube
machine itself, so as to perforate the strip of paper from which the cop tube is made,
either before or after the paste has been applied thereto, preferably before and thus
form the perforations in the paper cop tube whilst it is being formed, thereby
retaining its proper shape and avoiding the necessity of a second operation and
opening of the paper cop tube.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a side view of the portion of a cop tube making machine, to which the
punching apparatus is applied,
and
Fig. 2
a plan of a strip of paper perforated in the cop tube making machine,
Fig. 3, a perspective view of a cop tube made thereby from a strip of perforated
paper.
În carrying out my invention and referring to the figures generally, a is the
punching apparatus, the bed plate of the cop tube making machine, c the paste
roller, &e the feed rollers, f the punches and g the die of the punching
apparatus, h the strip of paper from which the cop tube i is made, k the knife which
cuts and the spindle which winds the paper strip into tube form.
The said punching apparatus may be of any well known type or convenient
construction, and for example, consist of a frame a secured to the bed plate b of the
cop tube making machine, between the paste roller c and feed rollers e containing
a number of punches operating in conjunction with a corresponding die g, over
which passes the paper strip h, from the roll from which the cop tube i is made.
The punches may be actuated by means of a cam, eccentric, screw, lever, or
otherwise, as found most convenient, from any moving part of the cop tube making
machine, by the aid of suitable gearing and levers, and the cop tube making machine
itself may
be of any well known type or convenient construction.
The punch holes in the die y and the punches are so positioned in relation to
each other, that on the knife k having cut the previously perforated paper strip h
at the dotted line ³, see Fig. 2, and on it being wrapped round the spindle I once,
the perforations m of the second wrap will meet those of the first wrap, or vice versa,
and thus come opposite to each other, so as to form a clear passage for the dye or
other liquor.
It will be understood that I do not confine myself to the exact position of the
punching apparatus a in the cop tube making machine, as shown in the drawing, as
the perforations m in the paper strip h may be produced in other positions, for
instance, below the bed plate b.
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―
1st. A tube for the reception of yarn, consisting of a strip of paper h
perforated previously to being wound or rolled into tube form, the perforations m

page_text: of one warp meeting those of the other warp, substantially as and for the purpose
set forth.
2nd. The combination with a paper tube making machine of suitable construction,
of a convenient form of punching apparatus a suitably positioned in the cop tube
5 making machine, between the paper roll h' and feed rollers e, adapted to perforate
the strip of paper / fed in, previously to being wound or rolled into tube form,
substantially as and for the purpose set forth.
