Improvements in Machinery or Apparatus for Winding Yarns or
Threads.
I, WILLIAM THOMAS STUBBS of Mill Street Works, Ancoats, Manchester, in
the County of Lancaster, Machine Maker, do hereby declare the nature of this
invention to be as follows:-
My invention relates to machinery or apparatus for winding yarns or threads.
In machinery or apparatus for winding yarns or threads it has hitherto been
customary to employ drag rails or bars covered with flannel or cloth, or iron rods
with flannel washers threaded on or other like devices in order to impart the
requisite "drag" or tension to the yarns or threads in their passage from the cops,
bobbins or hanks from which they are being unwound to the spindles, bobbins or
tubes or other objects upon which they are being wound. In the use of drag rails
or bars covered with flannel or cloth or flannel washers or other like devices for
the purpose above mentioned it has been found that the friction of the yarns or
threads upon the flannel or cloth has caused projecting fibres to be detached from
the yarns or threads and that the detached fibres have accumulated upon the flannel
or cloth and afterwards have been taken up in lumps by the yarns or threads on to
the bobbins spools, tubes or other objects upon which they are being wound,
thereby causing inferior work to be produced in the subsequent processes to which
the yarns or threads are subjected. It has also been found in the use of rails or
bars covered with flannel or cloth or flannel washers or other like devices that it is
impossible to impart a perfectly regular and equal drag to each yarn or thread
while being wound.
My invention has for its object to avoid the use of drag rails or bars covered
with flannel or cloth or flaunel washers and other like devices and thus to prevent
the accumulation upon the flannel or cloth of the drag rails or bars of "fluff" or
detached fibres which might be carried away by the yarns or threads on to the
bobbins, spools, tubes or other objects upon which they are being wound and cause
inferior work in the subsequent processes and to cause each yarn or thread to be
subjected to a more regular and equal "drag" or tension while being wound than
has hitherto been possible. My invention also has for its object to take up any
slack which may at any time occur in the winding of yarn and thread and
especially in cases where two or more yarns or threads are being wound upon the
same bobbin or spool in stop motion winding machines.
According to my invention I cause the “drag” or tension of each yarn or thread
being wound in a winding machine to be caused by a wire or wires suspended upon
such yarn or thread which wire or wires is or are made of a weight adapted to the
counts or strength of the yarn or thread to be wound and may have an adjustable
weight or weights applied to it or them. In order that the wire or wires suspended
upon each yarn or thread may be prevented from being carried along with such
yarn or thread while it is being wound I provide suitable boxes or holders each of
which may hold or guide one wire or two or more wires. The wire or wires
suspended upon each yarn or thread is or are so formed that it or they may be
capable of sliding freely in the box or holder or boxes or holders in which it or
they is or are mounted while at the same time such wire or wires may be incapable
of escaping from the said box or holder or boxes or holders unless such box or
holder or boxes or holders are opened for the purpose of removing or changing
such wire or wires. By each yarn or thread which is being wound in a winding
machine being caused to support a wire or wires adapted in weight to the strength
or count of the yarn or thread and to the tension to which it is desired to subject

page_text: such yarn or thread I am enabled to ensure that each yarn or thread shall be
subjected to a regular and equal tension and that any slackness which may from
time to time occur in the winding of such yarn or thread shall be taken up. By
dispensing with a cloth or flannel arag or flannel washers and other like devices I
avoid the rubbing off of small fibres from the surfaces of the yarns or threads
being wound and thus avoid the weakening of such yarns or threads and the loss of
"fulness" which results from the employment of a flannel drag, and I also prevent
"fluff" or lumps of detached fibres from passing on to the bobbins, spools, tubes or
other objects upon which the yarns or threads are being wound.
My invention is applicable to winding frames or machines of any class in which
it may be necessary or desirable to have a certain amount of drag or tension
imparted to the yarns or threads being wound or where it is desirable to avoid the
use of a cloth or flannel drag, or flannel washers or other like devices and my
invention may be applied to machinery or apparatus for winding yarns or threads
from cops, bobbins or hanks or any of the other forms or bodies into or upon which
yarns or threads may be wound.
My invention is particularly applicable to machines in which two or more yarns
or threads are being wound upon the same bobbin or spool in stop motion winding
machines, as in such machines when one yarn or thread of a pair or set becomes
broken or terminates the other or others is or are allowed to become slack and
unless the slackness be taken up an uneven tension is produced in the cop, bobbin
or spool or other form into which the yarns or threads are being wound and my
invention in this respect is very particularly applicable when three two-fold yarns
are being wound from bobbins on to another bobbin or spool prior to being twisted
together into a six fold thread. In this case the slackness is caused by the "over
running" of the bobbin or bobbins on which is or are wound the unbroken yarn or
yarns of any particular set from which the yarn is being wound.

Improvements in Machinery or Apparatus for Winding Yarns
or Threads.
I, WILLIAM THOMAS STUBBS of Mill Street Works, Ancoats, Manchester, in
the County of Lancaster, Machine Maker 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 :-
"
My invention relates to machinery or apparatus for winding yarns or threads.
In machinery or apparatus for winding yarns or threads it has hitherto been
customary to employ drag rails or bars covered with flannel or cloth or iron rods
with flannel washers threaded on or like devices in order to impart the requisite
drag or tension to the yarns or threads in their passage from the cops, bobbins,

My invention has for its object to avoid the use of drag rails or bars covered
with flannel or cloth or flannel washers and other like devices and thus to prevent
the accumulation upon the flannel or cloth of the drag rails or bars of "fluff" or
detached fibres which might be carried away by the yarns or threads on to the

My invention is applicable to winding frames or machines of any class in which
it may be necessary or desirable to have a certain amount of drag or tension
imparted to the yarns or threads being wound or where it is desirable to avoid
the use of a cloth or flannel drag or flannel washers or other like devices and my
invention may be applied to machinery or apparatus for winding yarns or threads
from cops bobbins or hanks or any of the other forms or bodies into or upon which
yarns or threads may be wound. My invention is particularly applicable to
machines in which two or more yarns or threads are being wound upon the same
bobbin or spool in stop motion winding machines as in such machines when one
yarn or thread of a pair or set becomes broken or terminates the other or others
is or are allowed to become slack and unless the slackness be taken up an uneven
tension is produced in the cop, bobbin or spool or other form into which the yarns
or threads are being wound and my invention in this respect is very particularly
applicable when three two-fold yarns are being wound from bobbins on to another
bobbin or spool prior to being twisted together into a six fold thread. In this case
the slackness is caused by the "over running" of the bobbin or bobbins on which is
or are wound the unbroken yarn or yarns of any particular set from which the yarn
is being wound.
In order that my invention may be more fully understood. and more readily

page_text: carried into effect I will now proceed to further describe it with reference to the
accompanying drawing in which
Fig. 1 is an end view partly in section and Fig. 2 a front view of so much of a
machine for winding yarns or threads from bobbins as is necessary to illustrate my
invention and Figs. 3, 4, and 5 are respectively a front view, a plan partly in
section, and a transverse section of the box or holder employed in conjunction with
the wires suspended in accordance with my invention, upon the yarns or threads
being wound.
In the accompanying drawing (a) (a) (a) are the bobbins from which the yarns
or threads (A) (A) (A) are to be unwound and (b) is the bobbin or spool upon
which the said yarns or threads are to be wound by the friction between the
winding drum (c) and the surface of the yarns or threads wound upon the bobbin
or spool (6). The bobbins (a) (a) (a) and the bobbin or spool (b) and the drum (c)
are mounted in any suitable manner and do not form any part of my invention.
The yarns or threads in their passage from the bobbins (a) (a) (a) are caused to
pass over bars or rails (d) (d) supported in brackets (e) of which one only is shown
in the drawing which brackets (e) are secured to any suitable part of the machine.
Upon each of the yarns or threads (A) is suspended a wire () which imparts
tension to the said yarn or thread. The wires (f) are so formed that each of them
is capable of sliding freely upwards and downwards in a box or holder (g) shown
upon a larger scale in Figs. 3, 4, and 5 which box or holder (y) prevents the
wires () from being carried along by the yarns or threads (A) in their movement.
The box or holder (9) may be of any construction which may be suitable and the
wires () must be so formed as to be incapable of escaping from the box or
holder (9) except at such times as the said box or holder (g) is opened in order that
the said wires (f) may be removed or changed. One mode in which the said
wires (f) may be inade incapable of escaping from the box or holder (9) except at
such times as such box or holder (9) is opened, is clearly indicated in the accom-
panying drawing which also clearly indicates the manner in which the box or
holder (9) may be opened in order to allow the wires () to be removed or changed.
The box or holder (9) may be secured to any suitable part of the framework of the
machine. Each yarn or thread (A) being unwound from the bobbins (a) (a) (a)
and wound upon the bobbin or spool (6) having to support one of the wires (f)
will be subjected to "drag or tension thereby and by the wires (1) being made
of weights corresponding to the tension to which the yarns or threads (A) are to
be subjected and corresponding to the strength or counts of such yarus or threads
it is easy to secure that an equal and regular "drag" or tension shall always be
exerted upon each of the yarns or threads and the breakage or termination of one
yarn or thread is prevented from causing any interference with the tension of the
other yarns or threads. As the wires (f) are capable of sliding freely upwards
and downwards in the box or holder (g) any slack which is likely to occur in any
of the yarns or threads (A) will be taken up by or compensated for by the descent
of the wire (f) supported by such yarn or thread.
"
In order to show the manner in which my invention may be employed in a stop
motion winding machine in which the breakage or termination of one of two or
more yarns or threads being wound upon a bobbin tube or spool or other object is
caused to bring about the stoppage of the winding of the other yarn or thread or
yarns or threads on to the said bobbin, tube or spool or other object I have
indicated in Fig. 1 a detector wire or faller wire (1) as being suspended upon each
of the yarns or threads (A) and in such figure have also indicated a shaft (i) upon
which may be mounted a revolving or oscillating ratchet or wiper into contact with
which each of the detector or faller wires (h) will pass as soon as the yarn or
thread upon which such detector or faller wire (4) is suspended breaks or terminates.
As the provision of a stop motion or arrangement of detector or faller wires forms
no part of my invention I will not further describe such an arrangement.
In cases in which it may be desirable to subject the yarns or threads being
wound to a greater degree of tension than can readily be exerted by the suspension

page_text: 66
upon each of such yarns or threads of a simple wire I may suspend a weight or
weights to the wire (f) suspended upon each yarn or thread and so cause a greater
drag" or tension to be exerted upon such yarn or thread or I may cause two or
more wires arranged and mounted in a manner similar to that in which the wires (f)
are arranged and mounted and provided or not provided with a weight or weights
secured thereto to be suspended upon each yarn or thread..
The extent of the motion in an upward and downward direction permitted to the
wires (f) suspended upon the yarns or threads being wound may be made as small
or as great as may be desirable in accordance with the circumstances under which
my invention is to be employed.
Although I have in the accompanying drawing illustrated my invention as applied
to a stop motion winding machine for winding yarns or threads from bobbins on to
bobbins or spools my invention is applicable to winding frames or machines of any
class in which it may be necessary or desirable to have a certain amount of drag or
tension imparted to the yarns or threads or where it is desirable to avoid the use
of a cloth or flannel drag or flannel washers or like devices and my invention may
be applied to machinery or apparatus for winding yarns or threads from cops
bobbins or hanks or any of the other forms or bodies into or upon which yarns or
threads may be wound and winding such yarns or threads into or upon pirns,
bobbins, spools, tubes or hanks or any of the other forms or bodies into or upon
which yarns or threads may be wound and my invention is as has been stated above
particularly applicable to machines in which two or more yarns or threads are being
wound upon the same bobbin or spool in stop motion winding machines.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The herein before described means for subjecting to "drag" or tension the
yarns or threads being wound in a machine for winding yarns or threads and which
consists in a wire or wires (f) suspended upon each yarn or thread and mounted
in a box or holder (g) substantially in the manner and for the purposes hereinbefore
described.
