1, JOHN DEMPSTER WHYTE of number eight South Parade, Manchester, Yarn
Agent do hereby declare the nature of this invention to be as follows:-
An improved method of winding whereby yarn may be wound into cop form on
the bare spindles, without pirus or spools or tubes such as yarn is commonly wound
upon; and also without cups such as yarn is commonly wound into, so that all
frictional contact with the yarn such as is caused by cups is entirely avoided. Yarn
may also be wound upon pirus or spools or tubes if desired, but without cups and
their frictional contact with the yarn. Parts of this method of winding are also
applicable to winding into warping bobbin form on tubes without flanges at the ends,
upon friction wheel machines such as are used for silk bobbin winding without
frictional contact with the yarn such as is caused by drums in drum-winding
machines.
For winding into cop form, my principle is to give each spindle its own
accompanying independent traverse guide, and so to adjust such traverse guide that
it may be moved along upon that which carries it whilst it is doing its traversing
movement, and that it may be automatically and singly stopped in its progress upon
the breaking of the thread which is being wound. The spindles are arranged at
right angles to the main driving shaft and are driven therefrom in any ordinary
manner that will admit of each spindle being easily put out of gear. Parallel with
each spindle are two small shafts driven conjointly with the spindle so that spindle
and shafts can be simultaneously stopped. The shaft nearest to the spindle has a
screw thread extending along upon the greater portion of it, and the other shaft
carries a cam upon it. The cam may be an ordinary cylindrical cam, or it may be a
wheel so shaped upon its boss that the diameter of the wheel is not at right angles to
the shaft upon which it is placed and the rim of the wheel thereby describes the
required oscillatory revolution. One end of a thread-guide is adjusted upon the
cam so that as the cam revolves the desired to-and-fro movement of the thread-guide
takes place. The revolution of the cam may be regulated at a speed to give slow
traverse upon pirus or spools or tubes, or to give necessary quick traverse upon bare

page_text: spindles. Secured upon, but movable along, a rod which is placed parallel with and
between those two shafts is a block with a half-nut on one side of it which half-nut
fits into the screw thread. A small arm fixed to that block extends to the thread-
guide, which thread-guide is pivotted upon the end of that arm at such a distance
between the cam and the spindle as shall give the desired length of traverse upon the
spindle when the end of the thread-guide is caused to oscillate by the revolving cam.
The cam is so keyed upon its shaft that whilst the shaft revolves and carries the cam
round with it, the cam may at the same time be moved along the shaft. Another
arm fixed to the half-nut block extends to the cam, and is swivelled upon one side of
the cam in such a manner that as the half-nut block is moved along in the desired
direction by the revolving screw-threaded shaft, the revolving cam is moved with it;
and consequently, whilst the revolution of the cam causes the end of the thread-guide
to give the requisite to-and-fro motion of the thread upon the spindle, the slow
progress of the cam and thread-guide along towards the point of the spindle gives
the proper conical shape to the cop by carrying the thread as it is being wound slowly
nearer to the point of the spindle. An automatic stop-motion is required to prevent
the progress of cam and thread-guide along towards the point of the spindle when
there is no thread being wound. Such a stop-motion is effected upon the breaking of
a thread by the dropping of the end of a lever which is supported by the thread
whilst unbroken. The screw-threaded shaft has a projection upon it which comes into
contact with the lever as the end of the lever falls, and so throws it into contact with
the spindle's driving connection that the spindle and the parallel shafts are released
from their driving power and immediately stopped; thereby the progress of cam
and thread-guide towards the point of the spindle is likewise stopped. So near to
the end of the spindle as shall coincide with the desired length of the cop, a small
arm attached to that stop-motion lever is placed in a vertical position in the path of
the gradually approaching thread-guide, which thread-guide at last comes into
contact with that arm and thereby the lever is made to disengage the driving of the
spindle and shafts as already described. Whilst the spindle and shafts are thus
disengaged from the driving, the half-nut block, taking with it the cam and thread-
guide, is moved back into position for starting afresh.
For winding into warping bobbin form the screw-threaded shaft and half-nut are
not required, but the thread-guide will receive its to-and-fro motion from a suitable
cam as already described. The end of the thread-guide which is next to the bobbin
or tube carries underneath it a small roller which rests lightly upon the yarn on the
tube, thereby keeping the thread in winding close to the bobbin or tube. If desired,
the traverse may by this means be slightly shortened as the winding proceeds, for,
as the thread-guide is slowly raised by the increasing quantity of yarn upon the tube,
the point upon which it is pivotted may be caused to recede, so that the distance from
pivot to tube will be lengthened and the distance from pivot to cam will be shortened,
therefore the traverse will proportionately shorten.

I, JOHN DEMPSTER WHYTE, of 8 South Parade, Manchester, Yarn Agent, 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:-
An improved method of winding whereby yarn may be wound into cop form on the
bare spindles without pirus or spools or tubes such as yarn is commonly wound upon;
and also without cups such as yarn is commonly wound into, so that all frictional
contact with the yarn such as is caused by cups is entirely avoided. Yarn may also
be wound upon pirus or spools or tubes if desired, but without cups and their
frictional contact with the yarn. For this winding into cop form, ny principle is to
give each spindle its own accompanying independent traverse guide, and so to adjust
such traverse guide that it may be moved along upon that which carries it whilst it is
doing its traversing movement, and that it may be automatically and singly stopped
in its progress upon the breaking of the thread which is being wound.
In order that my said invention and the manner of performing the same may
be properly understood, I will now proceed to describe the same in detail, with
references to the accompanying explanatory Drawings, which I have marked with
figures corresponding with those in the following descripton. The same reference
figures are applied to the same parts wherever they may be repeated.
Figure 1 represents my method of building tho yarn in cop form. Parallel with
a spindle 1 is a small shaft 3 upon which a cam 4 is so adjusted that whilst the
shaft 3 revolves and by means of a fixed key 5 upon it causes the cam 4 to
revolve with it, the cam 4 may at the same time be caused to slide along upon its
shaft 3. This cam is a simple wheel so shaped upon its boss that the diameter of
the wheel is not at right angles to the shaft upon which it is placed and the rim of the
wheel thereby describes the required oscillatory revolution. Any ordinary cylindrical
cam with a zig-zag groove encircling it may be used if preferred. Parallel with and
between the spindle 1 and cam shaft 3 is another small shaft 6 which has a screw
thread extending along the greater part of its length. This screw-threaded shaft 6 is
below the spindle 1 but placed a little to one side and the cam shaft 3 is similarly
placed below the screw-threaded shaft 6. This may be arranged as thought desirable
for the saving of space in the length of the machine. A square block 7 has a half-nut
on one side of it which half-nut fits upon the screw thread. Whilst this half-nut is
held in contact with the screw-threaded shaft 6 by a small rod 8 which passes through
the half-nut block 7 and is parallel with the screw-threaded shaft 6, the revolution of
the screw-threaded shaft moves the half-nut block 7 along in the direction and at the
speed which are required for the building of the yarn in proper cop form 2. By
means of a thread guide 10 the thread of yarn is guided on to the spindle or tube
thereon through a suitable eye near to the spindle. The other end of this thread
guide 10 is resting upon the cam 4 with a small finger on each side of the cam or (if
the cam is a grooved one) with a small roller running in the groove of the cam,
so that, as the cam makes its oscillatory revolution, this end of the thread guide
receives therefrom its to-and-fro motion. As the thread guide 10 at that part of
it which crosses the half-nut block 7 (properly distanced between the spindle 1 and
cam sbaft 3) is pivotted upon the half-nut block 7, the end of the thread guide 10

page_text: next to the spindle oscillates similarly to the end which is upon the cam 4, thereby
the requisite traverse or to-and-fro motion is given to the guide eye whilst the
thread is being wound. When quick traverse is necessary for winding upon the
bare spindle this simple guiding motion being light in its construction has an
especial advantage over the ordinary methods of moving a heavy longitudinal rail
up and down or backwards and forwards, as such a rail is not moved very con-
veniently at a very great speed. A small arm. 9 extending from the half-nut block 7 to
the boss of the cam 4 encircles a groove in said boss or is swivelled on to the end of
said boss in any suitable manner that will not retard the revolution of the cam 4. By
means of this arm which is carried along with the half-nut block 7 in its progress
towards the point of the spindle the cam 4 is caused to slide along upon its shaft
similarly towards the point of the spindle. Therefore whilst the thread guide 10 is
with its to-and-fro motion guiding the thread upon the revolving spindle or tube
thereon, the thread guide is at the same time being carried onward at a suitable speed
to properly build the yarn in cop form 2. The thread guide 10 may have a secondary
arm and guide eye for the regulating of tension on the thread. This may be arranged
as shewn in Figures 1 and 2. A small arm pivotted to the guide 10 a little above its
pivot on the half-nut block 7 is elbowed to a longer arm 11 extending towards the
cop 2 and ending with a guide eye similar to that on the end of the guide 10. This
longer arm 11 is pivotted on the upper corner of the half-nut block 7 so that when
the thread guide 10 is moved towards the nose of the cop 2 and less length of yarn is
thereby being wrapped round the nose of the cop than round the thicker part, the
arm 11 (through the eye of which the yarn is first threaded) will be moved in the
opposite direction as in Figure 2. If desired, the cam shaft 3 may be placed next to
the spindle as in Figure 3, and the thread guide 1 would in such case be pivotted at
its end upon the half-nut block 7 and receive its to-and-fro motion near its middle
from the cam 4. An arrangement of parts may be made whereby spindles and cam
shafts and screw-threaded shafts would work vertically; and I wish it to be under-
stood that I do not confine myself to the exact details or relative proportions as
illustrated by my Drawings, as my "improved method of winding" may be adapted
to differently constructed frameworks of machines.
Upon the breaking of a thread, the progress of the thread guide 10 towards the
point of the spindle must be stopped so that the form of the cop may be perfectly
uniform. If the cam shaft 3 and the screw-threaded shaft 6 are driven by their
connection with the spindle which may be done by any suitable well-known means,
then it is only necessary that a stop-motion should be applied to the stopping of the
spindle 1. This is done by means of a rod 12, as in Figure 4, similar in length to
and parallel with the spindle. A drop-wire 13 which is supported by the thread so
long as it remains unbroken is attached to one end of a small horizontal lever 14
which is pivotted upon an upward projection 15 from the rod 12. This horizontal
lever 14 is so nearly balanced that the thread which supports the drop-wire 13 and
thereby holds up
the end of the horizontal lever 14 has as little drag upon it as
possible whilst thus supporting the drop-wire 13. When this drop-wire 13 falls by the
breaking of a thread releasing it, that end of the horizontal lever 14 to which the
lower end of the drop-wire 13 is attached will fall into contact with a revolving
shaft 16 having two or more fingers upon it which so strike against the angle end of
the horizontal lever 14 that the upward projection 15 to which this horizontal lever is
attached is pulled forward so far that the rod 12 being thereby similarly pulled
forward moves the wharve 20 on the spindle so as to disengage the spindle from
the clutch of that revolving wharve 20. Any ordinary means of thus disengaging the
spindle may be used. The rod 12 may either be connected to a movable wharve upon
the spindle by a lever, or, in the employment of two wharves on the spindle, one fast
the other loose, the rod 12 may be connected to a small strap-guide which pushes or
pulls the strap or banding from the fast to the loose wharve or rice versa.
the rod 12 may by the aforementioned pulling forward of the upward projection 15
remain in that position until it is desired to put the spindle again into motion,
a small downward projection 17 similar in shape to the upward projection 15, but
That

page_text: reversed, hangs through a suitable bracket down on to the top of the upward
projection 15. One side of each of these projections 15 and 17 is rounded off towards
the end and the opposite side is straight. The rounded parts lie against each other
so long as the rod 12 is held back by the spring 19 and has not been pulled forward
by the action arising from the breaking of a thread as already described. When the
rod 12 however is pulled forward by that action the rounded part of the upward
projection 15 pushes the downward projection 17 up out of its way until the upward
projection 15 has moved so far forward that the downward projection 17 falls down
behind it with straight side against straight side as in Figure 5, and thereby prevents
it slipping back into its former position. When it is desired to put the spindle and its
attendant shafts into motion again the worker, having adjusted the thread in the eye
on the upper end of the drop-wire 13, has only to lift the downward projection 17 by
the knob 18 out of contact with the straight side of the upward projection 15
and then the rod 12 to which the upward projection 15 is attached will be pushed
back into its former position by the spring 19; thereby the revolving wharve on the
spindle will be so moved as to cause the spindle to revolve with it, or in the case of
two wharves, one fast the other loose, the strap or banding will be moved from the
loose on to the fast wharve, and the winding proceeds. To ensure the action of the
stop-motion when a cop is complete and no broken thread actuates the stopping
movement, a small projection 21 hangs down from the rod 12 in the path of the
slowly approaching half-nut block 7. The half-nut block at last in its outward
movement pushes that projection 21 along with it, and thereby the rod 12 is pushed
forward until the upward projection 15 is moved to allow the downward projection 17
to fall behind it in the manner already described when the stop-motion is at
once effected.
As certain varieties of winding may require a very slow revolution of the screw-
threaded shaft 6 and also an easy method of changing the speed of the same, it will be
desirable in such cases to impart the desired slow rotatory motion to the screw-
threaded shaft 6 by a longitudinal shaft 22 extending along the front of the machine.
By speed-cone pulleys or any other well-known means which may be employed at the
end of the machine to drive this longitudinal shaft 22 its speed may be easily regulated
and changed as desired. Similarly the cam shaft 3 may receive its rotatory motion
from another longitudinal shaft in the centre of the machine, the speed of which may
be similarly regulated and changed for the purpose of giving quick or slow traverse
to the thread as it is being wound. Under this arrangement of parts, the stop-motion
as shewn in Figures 6, 7 and 8 is different in some details to that already described.
A rod similar to the rod 12 which stops the revolution of the spindle will still be
employed, but thereby the spindle alone is stopped, as the cam shaft 3 and screw-
threaded shaft 6 are not now driven by the spindle. On the longitudinal shaft 22, a
bevelled friction wheel 23 is in frictional contact with a bevelled friction wheel 24
upon the end of the screw-threaded shaft 6. A groove round the boss 25 of the
friction wheel 23 on the longitudinal shaft 22 is encircled by a circular piece or
ring 26. A vertical lever 27 is hinged on to a short arm hanging down from this
circular piece or ring 26 and is pivotted near its middle upon a short rod 28 which is
A horizontal lever 80
secured in the longitudinal rail 29 in the front of the machine.
similar to the horizontal lever 14 already described is pivotted upon the lower end of
the vertical lever 27 and is connected with the drop-wire 31 in a similar manner to
the connection of 14 and 13 as already described. Upon the cam shaft 3 and so near
the end of it as to be under the angle end 32 of the horizontal lever 30 are fingers 33
(which may be two or more) one of which as the cain shaft 3 revolves will strike
against the angle piece 32 when it is allowed to fall by the breaking of a thread, and
will thus pull along the lower end of the vertical lever 27 in such a manner that
the upper end of this vertical lever by its connection with the ring 26 encircling the
groove in the boss 25 will pull friction wheel 23 out of contact with friction wheel 24.
Thus the rotatory motion of the screw-threaded shaft is stopped. At that portion of the
vertical lever 27 which is pivotted on the rod 28 is an arm 34 bearing on its end a
weight 35 which is sufficiently heavy to hold the friction wheel 23 in contact with the

page_text: friction wheel 24 when they are not pulled apart by the action of the fingers 33 upon
the angle end 32. The rod 36 serves the same purpose as the rod 12 which as already
described stops the spindle, but upon this rod 36 there is a square projection 37
which is held against the vertical lever 27 by means of a spring 38 so long as this
vertical lever retains its perpendicular. When upon the breaking of a thread, this
lever 27 is thrown out of its perpendicular, this square projection 37 allows the rod 36
to be pulled forward by the spring 38, and at the same time prevents the lever 27
returning to its perpendicular. In order to set the spindle and screw-threaded shaft 6
in motion when the thread has been pieced up, the worker has only to push the
knob 39 inwards until the square projection 37 is moved along to allow the lever 27
to return to its perpendicular. When a cop is complete the stop-motion is actuated
by a sliding piece 40 in a groove cut lengthwise in the cam shaft 3. At the end near
to the fingers 33 this sliding piece has an upward projection 41 which branches
forward towards the horizontal lover 30. On the other end of this sliding piece 40
near to the approaching cam it has another small upward projection 42. When the
cam in its onward progress along its shaft has moved so far as to complete the cop
the end of the boss of the cam pushes the projection 42 and thus pushes the sliding
piece 40 along in its groove so that the projection 41 will then strike against the angle
end 32 of the horizontal lever 30 in the same manner and with the same stop-motion
effect as when the finger 33 does so.
When a cop is complete the half-nut block 7 and cam 4 require to be moved back
into position to begin winding a fresh cop. This may be simply done by means of the
rod 8 which holds the half-nut block 7 upon the screw-threaded shaft 6. This rod 8
is suitably mounted on a bearing in the longitudinal rail in the front of the machine
with a small knob 43 on its end by which it may be lifted up so as to let the half-nut
block 7 slide back to the starting point, which is indicated by a collar fixed on the
rod 8, and which may be moved, if it is desired to change the starting-point.
Whilst I have only referred to and illustrated one spindle, it will be understood that
the various parts described are applicable to each of as many spindles as may be put
upon the machine conveniently.
Whilst I have only referred to the winding of one thread for each spindle, it will be
understood that, two or more threads may be wound at the same time on to one cop.
In such cases a drop-wire and small horizontal lever as shewn by 13 and 14 in
Figure 4 or 31 and 32 in Figure 6 have to be used for each thread.
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 :-
:―
1. The combination and arrangement of a cam (4) and a half-nut block (7) in
conjunction with each other operating substantially as and for the purposes hereinbefore
described and illustrated by Figures 1, 2 and 3 on the accompanying Drawings.

arm (11) substantially as and for the purposes hereinbefore described and illustrated

mechanism substantially as hereinbefore described and illustrated by Figures 4 and 5
on the accompanying Drawings.
