Improvements in or relating to Machines for Winding Yarn, Thread,
" and other Material.
I, JOSEPHI ROBERT LEESON, of No. 226, Devonshire Street, Boston, Massachusetts,
United States of America, Manufacturer, 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:-
The object of the first part of my invention is to automatically perform certain
operations in the process of winding cylindrical or conical cops, the neglect of
which, would cause the production of inferior cops or packages; to provide means
for eliminating the adhering bunches of fibre and bits of foreign matter, com-
monly called
slubs," and to so effect the winding as to prevent the cops or
packages of yarn from bulging at the ends. The object of the second part of my
invention is to facilitate the winding of cops of conical form, without necessarily
employing a winding machine specially constructed for conical winding.
.
In producing cops or cones, of the character set forth in Letters Patent
No. 6497 of 1892, and especially in using the machines like those of Letters
Patent No. 17,123 of 1894, the thread guide must at all times be against the
surface of the package. In replenishing the supply, and at other times, in
piecing broken ends, it is frequently necessary to move the thread guide away
from the cop, in order to more easily get at the loose end of the yarn; and when
the cop has attained its full size, the guide should be moved back, away from
the cop, so that as the latter is removed, the guide shall not abrade the yarn,
nor displace the outer coils. It is now customary to move the guide away by hand,
when piecing, but careless operators often neglect to replace the guide against
the surface of the cop before restarting the winding and again, when the package
is completed, as they have no loose end to look out for, they frequently neglect to
move the guide away, preparatory to removing the package from the winding
spindle.
The bulging referred to is due to the following cause. With machines, in
which the winding spindle has a constant speed of rotation, the increasing lineal
speed of the material wound, due to the increase in diameter of the package, causes
an increase of tension. This increasing tension, in conjunction with the inherent
elasticity of the material, causes the exterior layers of the package to exert a
constricting pressure upon the interior mass, thereby forcing the ends outward.
To obviate these difficulties, I have invented devices for mechanically with-
drawing the thread guide from the package whenever the machine stops, and if
desired, also for mechanically replacing it again when the winding is started:
and for mechanically gradually decreasing the tension on the material, so that
the constricting pressure of the exterior layers shall never be sufficient to result
in bulging.
I shall describe the first part of my. invention as applied to machines sub-
stantially such as are shown and described in Patent No. 17,123 of 1894, Figs. G
to 8 thereof. It is equally applicable, whether the machine winds cylindrical

page_text: packages or is fitted to wind cones, or in other machines where the speed of the
yarn gradually varies.
For convenience I shall designate the material wound as
'yarn," without
limiting myself thereto, for my invention is also available in winding other
materials.
In the accompanying drawings, Fig. 1. is a front elevation of the machine;
Fig. 2 is a side elevation; Fig. 3 is a part rear elevation; Figs. 4, 5, 7, 8, 9, 12,
13, 14 and 15 and 15" show details of the structure; Figs. 6, 10, 11, and 16 show
modifications of the structure.
The first part of my invention is illustrated in Figs. 1 to 16 in which A is the
frame of the machine, 9 the winding spindle, and 26 the shaft carrying the cam 1),
which, through suitable connections, imparts a reciprocating motion to the guide
carrier C and the guide i, attached thereto, by spring arms. S', S, and studs r²,
Figs. 13, 14, 16. F is a swinging frame, which. sustains and guides the carrier C
and which, pivoted concentrically with the cam shaft 26, permits the thread
guide to bear at all times against the package being wound; and to be pressed
back, away from the winding spindle with the increasing diameter of the
package.
The yarn passes over a pick up bar 5, so as to slip into the eye of the guide when
raised by the rounded end of the latter, and the ends of the bar are turned up
so that the guide cannot push the yarn over the end of the cop before the guide
can pick it up.
There is also a stopping device of any usual or suitable character connected
with the shaft 21, which is adapted to be turned by the spring 18 in the direction
indicated by the arrow, Fig. 2, to stop the winding. Attached to the shaft 21, is
a handle E, having an arm 45 provided with a detent shoulder 46 and with
a slotted arm or lever P. The detent lever E, forced toward the shaft 21 by
means of the spring 31 is also provided with a shoulder 43, which, when engaged
with the shoulder 46, resists the tendency of the spring 18 to rotate the shaft 21
to stop the machine.
Pivoted to the lever E is the end stop bar 51, having at its upper end a cam-
formed edge, adapted to engage the periphery of a rotating disk 53, on the
winding spindle 9, thereby forcing back the detent lever E, disengaging the
shoulders 43 and 46, and permitting the stopping device to operate to stop the
winding. Into the lower extremity of the end stop bar 51 is screwed the thread
bearing bar 56, which, held down by the yarn, under tension, normally restrains
the upper end of the bar 51 from engaging with the disk 53 to cause the winding
to stop. This bearing bar is bent as shown in Fig. 12, so as to be carried to
different positions by turning it in the socket of the bar 51.
A is a bracket to support the separable tension device and the pivot of a
block Q.
The tension device, as shown, consists of two separable combs c c¹ of sheet
steel, one rigidly attached to the bracket A' and the other pivotally attached
thereto, by means of the rod G, on which it swings freely, see Figs. 15 and 15°.
The tension fingers, or teeth of the combs are so related, that those on the movable
comb swing between and through those of the fixed or rigid comb, thereby
opening the tension device to receive the yarn. Attached to the movable comb,
by means of flexible connections, is the wire yoke a.
Into the threaded socket at the opposite side of the bar 51 screws a threaded
extension 56', of the bearing bar 56, by turning which the bearing bar 56 may be
loosened or fixed in place.
The arm P and the end stop bar 51 are, through a link o pivoted to the bar 51
at the lower end, so connected, that when the shaft 21 rocks, in stopping the
winding, the lower extremity of the bar 51 is depressed, causing the projection 56¹
to strive against a vertical projection or arm g of the block Q, swinging the latter
to one side and bringing an arm k against the yoke a of the tension device and
thereby forcing the tension open to receive the thread.

page_text: To the top of the tension bracket I attach the plate m (Figs. 1, 2, 3 and 5),
suitably formed to guide, in conjunction with the bent guide wire n, the yarn
to its appropriate place in the tension device, and into a slit m¹ in the plate.
The slit m Fig. 5, is made of such size that, the yarn will just draw freely
through it. In the process of spinning, bunches of fibre and sometimes of
foreign material are incorporated with the yarn, forming what are termed
slubs." The latter detract from the value of the fabric into which the yarn is
manufactured, and it is to eliminate them that I employ the plate m. The slit m¹,
while of size to admit the yarn, will not allow one of these slubs" to pass, so
that when such a "slub" occurs, the yarn breaks. The operator then removes
the "slub" before tying up the yarn. Incidentally, the plate serves to strip off
any loosely adhering bunches of fibre or of foreign material. The inner end of
the slit is wholly open, or communicates with an opening m³, which serves as a
vent for lint and dirt and prevents them from clogging the slit. The yarn, when
drawn through the plate m and carried by the guide has a reciprocating move-
ment, in the slit, corresponding to that of the reciprocating guide i, so that any
matter in the slit is pushed out by the thread at either end of the slit. Were
it not for this vent, the slit would become packed with the lint and dirt and
would be extremenly difficult to clear. It is essential that the slit be made to join
the hole at a tangent on the side toward which the yarn draws, as indicated, for
otherwise a shoulder would be formed, that, catching the yarn, would hold it,
thereby stopping its reciprocating movement. in the slit. Instead of the con-
struction shown in Fig. 5, the slit may be formed of two adjacent plates as in
Fig. 11. In cases where the slub catcher is not required, the plate m may be
replaced by a wire m³ (see Fig. 16) suitably formed to guide, in conjunction
with the wire n, the yarn into its appropriate position in the tensions.
In order to vary the tension upon the yarn as the packages increase in diameter
I so connect a tension weight W, or its equivalent with the movable comb that it
shall act thereon with constantly decreasing leverage. This may be effected in
different ways.
Thus to the frame F (Figs 2 & 3) is attached a counterweight F1 and to the
side of the latter, I pivotally connect a weighted lever M. Thus the lever may
have an arm 75 with pin 76 for receiving one or more weights W, and an arm
at 73 with an adjustable pin 73ª for attaching a connecting rod M². The arm 73
preferably balances the arm 75, so that the tension shall be due only to the
weight applied. The pin for attaching several weights W is of such formation,
that weights may be readily added or removed. Thus the outer end of the pin 76
is split, as is more clearly shown in Fig. 6, and the two portions are spread apart
so that they must needs be sprung together in order to receive the tension
weights. The split end is further so formed, that the weights can be readily
applied, and, having been applied, the expanded end of the pin restrains them
from being shaken loose or otherwise accidentally displaced.
A rod M serves to connect the arm 73 or the lever M with the yoke a, and is
extensible. Thus it consists of the sections 77, 78 and sleeve 78. The extremity
of the rod 77 is provided with a screw thread, adapted to engage with a corre-
sponding internal thread in the sleeve 78, Fig. 4. By screwing the section 77,
a greater or a less distance into the sleeve 78", the length of the rod M2 may be
varied, either to adapt the part 77 to any one of various positions of the pin 73",
or to adjust the position of the weight W.
The position of the lever M is such, that, when the thread guide is against
the spindle and before the cop is commenced the centre of the weight W shall
be on or near the horizontal line passing through the centre of the pivot M¹.
As the winding progresses, the guide i is pressed back, away from the cop causing
the weight W to rise.
As the weight rises, the leverage about its fulcrum,--the pivot M-decreases.
while the leverage of the tension about the same fulcrum increases, so that the

page_text: .
actual pressure on the tension diminishes gradually until the package has attained
its full diameter.
F
It is sometimes desirable to vary the rate at which the tension shall change,
or to cause a greater or less variation between the initial tension, applied at the
commencement of the cop, and the final tension, at its completion.
This can be, attained in several ways. I prefer to adjust the position of the
pin 73 Thus I provide a series of holes in the arm 73, in which holes thé.con-
necting pin 3 may be suitably inserted. It can also be accomplished by making
one arm of the lever M adjustable in respect to the other so as to be set at any
desired angle. As shown in Fig. 6, the arm 71 is adjustable on a hub of the
arm75.37
..!"
As the top of the frame F swings back, away from the spindle 9;' it is prevented
from returning thereto by a suitable detent R. As shown, the detent is pivoted
at 66 to the frame and provided with a cam 64. This latter member is so arranged
that its cam, surface constitutes a bearing for a toe 62 projecting from the
frame F. The cam 64 is suitably counterweighted at 68, so that as the frame F
moves back, the cam is kept constantly in contact with the toe 62: When it
becomes necessary to bring the guide back to the spindle in order to start a
new cop, the cam 64 is withdrawn, allowing the guide to resume its initial
position.
In order to mechanically move the guide away from the package when the
winding is stopped and, if desired, to also mechanically replace it against the
surface of the package before the winding is again started, I interpose suitable
connections between the cam 64 and the starting and stopping device or other
part of or on the machine, which connections, during the operation of stopping,
cause the cam 64 to force the guide i away from the package; and during the
starting, said connections withdraw the cam 64 from under the toe 62, allowing the
guide to return to the surface of the package; "and finally, disengaging from
the cam 64 leave the 'latter free to follow up the toe 62 during the subsequent
winding to prevent a return movement of the guide i.
I will now describe certain connections which have proved effective. A rotatable
disk S is pivotally attached to the frame A, by a pin S¹ (Fig. 2). From said
disk projects a small pins, Figs. 2, 7 and S. The latter is located at a slight
distance from the centre of the disk, so that as the latter rotates, the pin s, moves
in the arc of a circle, intersecting the pitch line of a curved rack or sector 64ª
attached to the cam 64. The disk S is so related to this sector that as the disk
is moved through a partial rotation, the pin s enters into engagement with the
teeth of said sector and after slighly moving the latter, emerges from said engage-
ment, leaving the sector and the cam 64, to which it is attached,
entirely unimpeded. This feature is essential, for the cam 64 'must,
at all times during the winding, be free to follow up the toe 62, to 'prévent
the return of the guide inward toward the spindle, from any position to which
it has been forced by the increasing diameter of the package. Further, when
the machine is stopped, to remove a completed package, the pins must be out
of engagement with the sector, so that the cam 64 can be moved back, to return
the thread guide to the spindle, preparatory to winding a new cop.
Attached to the disk S, on the side opposite that from which the pin s projects
is the toothed hub S. Meshing with the teeth on this hub is a toothed rack
on a rod X, which is connected with the lever P, or otherwise operated from
some part of the stopping and starting device.
When the stopping device operates, the starting lever arm P moving in the
direction indicated by the arrow Fig. 2 imparts to X a downward movement,
causing the disk S, to make a partial rotation. By this partial rotation, the pin s
is forced into engagement with the sector 64, pushes it in the direction indicated
by the arrow, Fig. 2, thereby moving the thread guide i away from the package
being wound, and then disengaging itself from the sector 64", leaves the cam 64
free to be moved in either direction.

page_text: When the handle E' is moved to start the winding, the disk S is rotated in the
opposite direction, and the pins enters into engagement with the sector 64",
withdraws the cam 64, from under the toe 62, thereby allowing the frame F,
acted on by the weights 61 (Fig. 3) on the arm 60, to swing in and carry the
guide to the surface of the cop, when the pin s again disengages itself from the
sector, leaving the cam 64 free to follow the toe 62 as the guide i is pushed back
by the increasing diameter of the cop.
It is obvious that the machine may be stopped at such a time that the pin s,
instead of properly engaging with one of the teeth of the sector 64", will strike
directly on top of a tooth, in such a manner as to prevent the action of the
device, and also the operation of the stopping device, and so stop the winding.
Moreover, the teeth on the sector 64, are of necessity quite fine, so that great
depth of tooth is inadmissible. It would then be necessary, unless otherwise
provided for, that the pins and the sector 64ª be very carefully fitted to insure
their working properly. Were the sector 64" located too far from the pivot 66
of the cam 64, the pins would, if rigidly connected with the member S "bottom"
in the sector with substantially the same result as when striking on the top
of the tooth as above set forth. I therefore so connect the pins with the member S
that it can yield slightly radially and I round the tops of the teeth of the
sector 64 so that the pin s, instead of striking dead on to top of a tooth will yield,
and passing over the obstructing tooth, enter into the adjoining tooth space.
Extending diametrically across the member S, and nearly through the same.
is the circular channel 80, in which moves a slide 81. guided by the pins 81"
working in the slot 80°. The pins is attached to S1, extending through the
slot and projecting into the recess 80b. The latter is enough larger than the
pin s to permit the requisite movement of the pin s. Behind the member 81 is
the spring 82, which forces the pin s outward from the centre of S, against the
opposite side of the recess 80b, and permits it to yield inward toward the centre
when it strikes an obstruction, as before described.
Fig. 10 shows another construction of the member S, by which the same result
is attained. In this case the slide 81 is replaced by the swinging arm 91 pivoted
on the pin 91. The pin s extends through the arm 91 into a socket or recess 90°
which limits its motion. The spring 92 held in the circular pocket 90, presses
the pin s outward.
Having described in detail my improved construction and indicated the relation
of its various members to those of an existing structure of winding machine,
I will now describe its action.
The machine being ready for winding, the handle E¹ stands in the position
indicated by the dotted lines, (Fig. 2) the pin 561 depressed, and in contact with
the arm holds the tension open.
The yarn is drawn through the tensions, and, guided by the wire and the
curved edge of the plate m, finds its position in the tensions and the slit in the
aforesaid plate. Thence it is drawn over the pick up bar 5 and attached to the
winding spindle. The winding is started by turning the handle E¹ to the right,
(Fig. 2) until the detent shoulders 43 and 46 engage. The thread guide i, passing
under the yarn, picks it up and lays it in place on the surface of the package.
The end stop bar 51 tends to assume its position of equilibrium, and in so doing,
its lower end rises until the bearing bar 56 comes in contact with the yarn, which,
under tension, prevents the cam surface of the upper end of 51 from coming into
contact with the rotating disk 53 on the spindle 9, to stop the machine.
Coincident with this action, the member Q, freed from the restraint of the
member 561, assumes a vertical position and, carrying the pin away from the
yoke a, allows the tensions to close under the action of the weight W acting
through the intermediate connections.
The movement of the handle E', to start the winding, also raises the connecting
rod X, causing the member S to make a partial rotation, carrying the pin sinto

page_text: connection with the sector 64", withdrawing the cam 64 from contact with the
toe 62 and causing the pins to emerge again from the sector, leaving the cam 64
free to return to contact with said toe 62 on the frame F.
During the process of winding, as the cop increases in diameter, the frame F
is pressed back from the spindle, this action causing the weight W to rise,
diminishing its effect on the tension. In the meantime the plate m cleans from
the yarn most of the "slubs." If one occurs which is too firmly incorporated
with the yarn to be eliminated, the yarn breaks and as the restraint is removed
from the bearing bar 56, it flies up, causing the machine to stop.
In the action of stopping, the upward movement of the slotted end of the
arm P, lifting the upper end of the bar 51, causes the tension to open, forces
the connecting rod X downwards causing the disk S to make a partial rotation,
and, through the pin s, the sector 64" and cam 64, swings back the guide frame F
and moves the guide i back, away from the package. This permits the operator
to tie up the loose ends, without touching the frame F. When the machine is
again started, the same cycle of operations occurs, the tensions being mechanically
closed and the thread guide i brought back against the cop.
While I have shown and described the pivoted or swinging guide carrier
frame F and means for moving it back mechanically on the stopping of the
machine, I do not limit myself to this construction, as the guide carrier may
slide back as shown in Letters Patent No. 6497 of 1892 and any suitable con-
nections may be employed for throwing it away from the cop when the machine
is arrested, and for releasing it and carrying it back when the machine is started.
It will further be evident that different devices may be used to mechanically
and gradually shift the relation of the combs c c² as the cop increases in size, and
that the various parts may be otherwise constructed than as shown. Also that
tension devices of different forms may be employed in some cases.
с
The second part of my invention relates to a coning attachment specially
adapted for machines of the construction above described, but adapted also to
other constructions is shown in Figs. 17 to 25.
In said Figures, Fig. 24 is a front view of a winding machine with my new
coning device attached; Fig. 25 is a side view of the same; Fig. 17 an enlarged
sectional view of the coning device; Fig. 18 a face view of one of the driving
gears; Fig. 19, an edge view of said gear; Fig. 20, a side view of the expanding
ring Fig. 21 is a view of an attachment for use with the cone spindle in winding
cylindrical packages; Fig. 22 is an end view of same; Fig. 23, a view of the
expanding pin.
The coning device is supported on the winding spindle with its axis so inclined
thereto that the element of the cone along which the traversing guide travels, is
parallel to the line of travel of said guide.
Upon the rotating spindle 9 is temporarily supported the cone member or
bearing K, prevented from turning with or about said spindle by means of the
pin 28 extending into a hole in the frame A of the winding machine and fastened
therein by means of the screw 27, or otherwise.
In order that the pressure of the screw 27 upon the pin 28 shall not force the
member K against the winding spindle, thereby causing undue friction, I pivot
said pin to the bearing K by a pin 28 so as to move slightly on the pin 28* to and
from the winding spindle.
The axis of the member K does not correspond with that of the spindle 9, but
is inclined thereto at such an angle, that each element of the cone tube, or
of the cone package being wound shall, when rotated between the spindle and
the traversing guide i, be substantially parallel to the line of travel of said
guide.
Upon the bearing K is carried and rotates the conical sleeve or tube carrier B¹
driven from the spindle 9, by means of a bevel or crown gear 40 which is attached
to the spindle by means of the screw 41 and the dowel pin 40d. The teeth
of the pinion mesh with corresponding teeth in the sleeve B equal in number to

page_text: those in the pinion, so that the sleeve B makes the same number of rotations as
the spindle.
To permit the sleeve B¹ to run freely and smoothly without excessive play, and
to adjust it to take up wear, the member K is pushed toward the pinion 40 until
the play is eliminated and is held firmly against longitudinal movement by
means of the pin 28 and the screw 27 which bears on an inclined face or seat
on said pin. This inclined seat is provided, because, in pushing the cone tubes
onto the carrier B', the tendency is to force the bearing K away from the
pinion, thereby causing or increasing play between the sleeve B and the
member K. With the pin beveled, as indicated, it is impossible to force the
member K back without first loosening the screw 27. Other means to effect this
result may be employed.
To insure that the bearing surfaces between the spindle 9, the sleeve B¹ and
the meniber K shall be maintained well lubricated, I provide in the member K
suitable chambers 22 and 23 which are filled with an absorbent, adapted to
retain a quantity of oil and deliver it to the bearing surfaces as needed.
:
Oil is introduced into the device through a suitable hole, as the hole t in the
stem of a detachable cap L which is suitably adapted to the tube carrier and
constitutes a prolongation thereof. As the coning device rotates, the oil works
back through the gearing, along the spindle 9 and between the member K and
the tube carrier B₁, lubricating the surfaces and replenishing the oil chambers.
As some of the oil will work out at the rear or base of the carrier B¹, I provide
a guard O which serves to intercept any drops which may be thrown off by the
centrifugal action which is incident to the high speed at which the tube carrier B¹
rotates. This is a very desirable feature, inasmuch as winding machines, are
set side by side, and any oil thrown from one winding spindle will spatter and
damage the package being wound on the spindle next adjoining.
The outer surface of the tube carrier B₁ is provided with longitudinal corruga
tions to hold the paper cone tube from slipping rotatively.
To prevent the tube from slipping longitudinally I use the split ring G,
encircing the tube carrier, or otherwise arranged, and circumferentially corrugated
and adapted to be expanded.
A sleeve H is adapted to slide on a stem of the cap L, and is adjusted thereon
by means of the screw j, adapted to an internally threaded, axial hole in said
stem. The cap L at 26 and the sleeve H at 25 have suitably beveled bearing
faces to correspond with an internal taper or bevel at each end of the split
ring G, so that the ring can be expanded or contracted by changing the relative
positions of the bearing faces.
I do not limit myself to a corrugated ring, though a ring provided with a con-
tinuous spiral corrugation as shown is preferable. The object of this corrugation
is to adapt the ring to make a firmer contact with the paper tube. This can
be attained in several ways, as for instance, by making a ring with a knurled
surface or by forming on the surface a series of circular rings.
The screw is provided with a knurled head, which abutting the end of the
sleeve H advances the latter along the stem 7, thereby expanding the split,
corrugated ring G and imparting to it, at the same time, a slight linear movement
toward the base of the cone.
As the ring expands, the tops of the projections or corrugations are forced
into the tube, and the linear movement of the ring tends to press the tube more
firmly upon the longitudinal corrugations. When the screw j is loosened, the
ring G contracts, due to its elasticity, forcing back the sleeve H and leaving the
tube of the package wound, free to be removed.
When the coning device is in operation, the end of the screw j
obstructs the oil hole t SO that no oil can leak out. When it
becomes desirable to oil the device, the screw j is withdrawn sufficiently, so that
the split ring may be drawn back to uncover the oil hole t and render it accessible.
The new arrangement of gearing herein described is greatly superior to that

page_text: :
previously employed, in that larger and stronger gears can be used, reducing
backlash and the extent of play at the periphery of the package.
With the
Furthermore, when, with the previous construction, the teeth of the gears
become damaged, it was necessary to replace the whole spindle 9.
present construction it is necessary to replace only the pinion 40 or the tube
carrier B, either of which are less expensive pieces than the spindle, 9..
When desired the same machine can be readily adapted to wind, cylindrical
packages as follows:
A tube holder for cylindrical tubes is secured by extending the spindle 9., One
means consists in the use of a section 20, Fig. 21, adapted to be suitably attached
to the spindle 9 as by means of a screw portion 20d which fits the hole provided
for the pinion screw 41. The arrangement for holding the tubes is a part of the
section 20 and is of a construction commonly employed. That is, the end of the
holder is split, and adapted to be expanded by means of a screw 21. A hole 21"
is provided for a suitable wrench, whereby the tube holder can be turned to
bind it securely, to the spindle 9.
While I have shown the parts H G ; in connection with the other parts the
latter may be used, alone, or with other means for prolonging the holder and for
securing the cone tube thereon.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is―
