Improvements in Machines for Winding Cords, Twines, Threads and
other Material.
I, JOSEPH ROBERT LEESON, of No. 226, Devonshire Street, Boston, Massachusetts,
United States of America, Merchant, do hereby declare the nature of this inven-
tion 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 machines for winding cords, threads, etc, in which
there is a rotating spindle and reciprocating guide; and my invention consists
in certain means for operating and varying the action of the guide to build up
cops of different lengths, with the cords laid in successive spirals, and in certain
details of construction and arrangement and in certain stop, driving and tension
devices, all as fully set forth hereinafter. One construction embodying my
improvements is shown in Figs. 1 to 11, and certain modifications in Figs. 12
to 23. In Figs. 1 to 11:-
Fig. 1 is a front elevation of a winding machine embodying my improve-
ments; Fig. 2, a side elevation looking in the direction of the arrow k, Fig. 1;

end view of the machine and showing the tension and stop devices, looking in
the direction of the arrow k¹, Fig. 1; Fig. 9, a plan view of part of the devices
shown in Fig. 8; Fig. 9 is an enlarged section of the tension wheel; Figs. 10
and 11 are modifications of the structure.
The construction of the apparatus shown in the drawings is intended more
especially for winding heavy twine or cord, such for instance as binding twine.
The machine as shown in Figs. 1 to 11 consists of a frame A, of any suitable
construction, supporting the winding spindle or cop holder w, which is driven
by or connected to a shaft W, and of a swinging frame F, which supports the
guide I, and also the devices which drive or impart reciprocation to the said
guide. These devices are of such a character that the winding spindle will rotate
one or more times at each full traverse of the guide, whereby the thread is laid
in helices which are crossed by the reverse movements of the guide, and I pro-
vide for winding cops of different lengths, with any desired number of turns in
each helix, by so constructing the guide operating devices that the traverse of
the latter may be extended or contracted as desired.
Different means may be employed for reciprocating the guide and varying the
extent of reciprocation, but in the construction shown I have provided a pro-
pelling screw 1, turning in bearings d', d², d, with a guide carrier J, supporting
the guide and reciprocated by said screw, together with means for reversing
the screw to alter the direction of travel of the guide. This reversing may be
effected by the contact of the guide or its carrier with shifting devices when the
guide reaches the end of its traverse, or it may be effected from any other part

page_text: of the moving apparatus. The screw D may be integral with the spindle D', or,
as shown in Fig. 11, the two parts may be separably connected. By this latter
means I overcome in a measure the difficulties incident to accurately aligning
the three bearings d¹, d², ³, as there is a joint allowing the two sections to
assume an angle to each other without friction, while the screw may be removed
for repairs without disturbing the gear and clutch mechanism. While this
jointed connection may be made in different ways, as shown in Fig. 11 the
spindle D has a transverse slot 84 receiving a corresponding tongue on the
Screw D. This tongue might be formed in different ways, but preferably consists
of a block 80 within the tubular end of the screw, with the tongue 81 extending
into the slot 84 in the head 85 of the shaft D', a pin 83 securing the block within
the screw.
As shown, the screw spindle D', supports two beveled gears 31, 32,
turning loosely on said spindle, and an intermediate clutch sleeve 33, each end
of which is adapted to engage with either one of the adjacent gears, the said
sleeve sliding on, but turning with, the screw shaft. As shown in Figs. 1, 3, 5,
11, the clutch faces are provided with teeth, but frictional engaging faces may be
employed, as in the modification shown in Fig. 10. With both of the beveled
gears 31, 32, engages a driving wheel 29, whereby the said gears are turned
continuously in reverse directions, so that by shifting the clutch member into
engagement with one or other of said gears the screw shaft is turned in one
direction or the other.
One means of shifting the sleeve 33 consists of a shifter rod c, sliding in pro-
jections in the bearings dd2, 3, and carrying an arm H, (see Figs. 3, 5, 7
and 10) which extends into a peripheral groove 33b, in the clutch sleeve 33, and
which rod is provided with contact pieces G G', arranged to be shifted by a pro-
jection 70, extending from the carriage J.
The carrier is recessed for the passage of the screw D, and is provided with
a screw 50, Fig. 6, terminating in a pin or teat 51, which engages with a shoe 52,
adapted to the channel between the threads of the screw, whereby the rotation
of the latter causes the traverse of the carriage.
While the guide I may be of any suitable construction, I show in the draw-
ing the form which I prefer for use with binder twine, heavy cord, etc., and
consisting of a bracket having ears 54, bolted to the carrier and provided with
a curved channel or groove for receiving the cord, the said channel being
smooth to avoid friction, and extended so as to deliver the cord against the cop
holder or cop at the point where the guide would bear upon the periphery of
the cop.
The frame has a counter-weight 59, which tends to swing the upper
part of the frame toward the cop while permitting it to swing outward as the cop
increases in size.
Any suitable means may be employed for driving the gear 29, upon the swing-
ing frame F. As shown, the shaft 25 of said gear carries at the lower end end a
beveled pinion 28, which gears with the bevel wheel 27, upon a shaft 26, which is
driven by a suitable train of gears L, Fig. 2, from the shaft W; or the shafts W
and 26, may be both driven from a main driving shaft. The frame F swings about
the axis of the shaft 26, as a centre, whereby the gears 27 and 28 are maintained in
mesh at all positions of the frame.
In the operation of the machine the gear 29 rotates continuously in one
direction driving the two gears 31 and 32 in opposite directions, the screw D
turning with the gear which is in engagement with the sleeve 33.
Assuming the screw to turn in the direction of the arrow, Fig. 3, the carriage
and its guide will be carried towards the contact piece G¹, and on striking the
latter, will carry the shifter rod c, together with the sleeve 33, in the direction
of the arrow o engaging the gear 31 with the screw shaft and reversing the
direction of rotation of the screw.
It will be seen that the length of the cop and the number of turns in each
helix will depend upon the extent of traverse of the guide, and that, by setting
the contact pieces G or G', in different positions, cops of different lengths may

page_text: be wound on the same machine. If for instance there are to be two turns of the
cord or thread around the core or cop in each helix the guide is carried to one
end of the cop holder and one of the contact pieces G, G¹, is set close to the
projection 70, and the holder is then rotated so as to make two complete rotations
carrying the guide along the holder to a position circumferentially in line with
the starting point of the helix at the opposite end. If the movement of the
guide was now reversed, a reverse helix would be laid and the guide would be
brought to the exact position in respect to the holder at which it started, and
the next helix would be laid or piled directly upon the first. For this reason
the contact piece which is last adjusted is not brought against the projection 70
and secured at once after the cop holder has made two complete rotations, but
is so adjusted and secured only after the cop holder, in addition to two com-
plete rotations, is turned a small fraction of a rotation, so as to carry the threads
and reverse the guide beyond a point circumferentially in line with the starting
point at the opposite end. It therefore follows that the shifter rod will not be
moved and the rotation of the screw reversed until the cop has made a little more
than two complete revolutions, counting from the point where the thread starts
at one end, and as a result each helix starts from one end of the cop at a point
circumferentially beyond that at which the preceding helix started from the
opposite end, and the thread of each helix at the ends of the cop is therefore laid
across the thread of the helix before laid, and then bent back and laid alongside
of the latter.
While I have referred to the cop as making more than two complete turns it
will be understood that practically the same result will be secured if the traverse
is slightly reduced, or the guide reversed just before reaching the point at which
the cop completed a rotation.
It will be seen that there are practically two adjustments for the contact
pieces G, G¹. One of these determines the general length of the cop; the other
is a fine adjustment extending or reducing the traverse of the guide, just so far
as may be necessary to carry the thread across the thread of the helix pre-
viously laid and reverse it at a point circumferentially slightly ahead of or behind
that where the helix was started at the opposite end.
One construction providing for such adjustment is shown in the drawing, best
seen in Fig. 4, where the contact piece consists of two parts g, h, the latter
adapted for fine adjustment on the part g, while the former which is tublar,
slides upon the shifting bar c, and may be secured at any point thereon by a set
screw As shown the part g is threaded to receive the part h, which may be
adjusted by turning it upon the part and then securing it in place by a jamb
nut . In practice the part g is adjusted, together with the part h to such
position that the projection 70, on striking the contact piece will cause the
reversal of the guide exactly at the point where one or more rotations or fractions
thereof are completed, and in line with the point from which the laying of a
helix started at the opposite end of the cop. The part is then turned so as to
cause the guide to be reversed slightly before or slightly after reaching the
point upon line with the starting point at the opposite end.
As the guides cannot be reversed until the clutch sleeve 33 is first disengaged
from the hub of one gear and then engaged with the hub of another, and as it
is desirable both to limit the period of shifting the sleeve, and also to prevent.
it from at any time stopping midway between the two engaging faces, I provide
means whereby to hold the sleeve in one position until the time of reversal, and
whereby to store-up power that will positively and quickly shift it the moment
the reversal should take place. An illustration of one means for securing this
result is best shown in Figs. 3 and 4 and consists of means for holding the rod c
frictionally against longitudinal movement. Thus there is a pawl t, having at
the end a triangular toe 2, the inclined faces of which are adapted to the opposite
inclined faces of a rib s¹ upon a block s, secured to the rod c.. A spring tends
to depress the pawl and prevent it from rising until the contact of the projec-
1

page_text: tion 70 with one of the contact pieces G G¹ overcomes the force of the spring
when the pawl is lifted, the rode and attached parts are shifted, and the toe (2
will then take a position upon the opposite side of the rib s to resist in like
manner the movement of the rod in the opposite direction. There are two
springs 41, 42, upon the rod c, one adjacent to each contact piece, with sliding
collars 47, 48, which are struck by the projection 70 so that each spring is. com-
pressed into a chamber in the contact piece, and power is thus stored, up to
aid to positively and quickly shift the shifting devices when they are released
by the lifting of either pawl.
The stopping devices may be of any suitable character. As shown in Fig. 1,
there is a driving belt Y, with a belt shifter N, upon a rod 21, to which is attached
a handle E, the end of which engages with a shoulder 43 thereby preventing a
spring 18 from shifting the rod and the belt shifter. When, however, the rod
is turned the handle is disengaged from the shoulder and the spring 18 moves the
rod longitudinally carrying the belt onto the loose pulley. This rocking of the
shaft may result from the contact of the cop with an arm 37 rotatively adjust-
able on the shaft 21, so that the machine is stopped when the cop reaches the
proper size. The rocking of the shaft also results from other causes hereinafter
described.
It is also essential to stop the machine when the supply becomes exhausted,
or when the cord breaks, or in case there is resistance to the feed of the cord,
as for instance results from the tangling of the latter. The stopping in the
latter case is especially important as an obstruction to the movement of the
cord will either cause it to break, or if the cord is strong will strain or break
the machine. To stop the machine under these conditions I incorporate in the
machine structure the devices illustrated in Figs. S and 9. As shown in said
Figures, an arm 22 attached to the shaft 21, carries at the end a guide pulley 23
over which the cord passes from a supply S and down through a tension device N.
If there is any obstruction to the movement of the cord the arm 22 will be drawn
down, rock the shaft 21 and stop the machine. A spring 13 tends to rock the
shaft to raise the arm 22.
There is another arm 14 carrying a pulley 15 and connected with a spring 16
which tends to draw the outer end of the arm downward. The pulley 15 lies
upon that part of the cord which is between the tension device and the cop,
so that if the cord should break or the supply become exhausted, the arm 14
will fall and through suitable connections stop the machine. As shown, a rod 17
connected with the arm 22 passes through an eye 20 on the arm 14, and is pro-
vided with a stop 19, with which the eye comes in contact when the arm 14 falls,
thereby drawing down the arm 22, rocking the shaft 21 and stopping the machine.
While any suitable form of tension devices may be used, I have found that
shown in Figs. 8 and 9 to be particularly effective. In these figures, M is the
frame of the device located at a suitable distance from the machine and carrying
wo grooved pulleys 51, 52, which conduct the cord to and from a horizontal
tension wheel N.
The latter has tension applied thereto in any suitable manner, as for instance,
by means of a tension disk 56, upon a pin extending through the shaft of the
wheel and secured to a lever 54, at. a point 55 beyond its fulcrum, a weight 59
being adjusted on the lever. Preferably the underside of the disk 56 and upper
face of the table M are provided with leather or other material that will secure a
steady frictional resistance to the rotation of the wheel N.
The wheel Fig. 9 consists of two connected sections vv, each having a hub
section 5 and rim 3 with radial arms so arranged that those of one section inter-
sect those of the other-being bent so that the bent parts of one series project
between the arms of the other. This forms a cord receiving groove that bends
the cord into a waved line and prevents slipping while permitting it to deliver
readily from the wheel.
Suitable devices are employed to hold the cord in the groove of the guide

page_text: wheel 51, as for instance a guide-eye 60; and to prevent the cord from dropping
from the groove when tension is relaxed I employ a spring finger 58, extending
into the lower part of the groove.
An ordinary feather might be used to prevent the rotation of the clutch sleeve 33
on the shaft ; as shown in Fig. 5, however, there is a sleeve 30 secured to the
shaft D with external longitudinal grooves receiving corresponding internal
projections on the sleeve 33.
The frame F below the screw is curved or rounded as shown in Figs. 1 and 6,
so that the cord can be conducted from one side of the frame beneath the rounded
face thus provided and to the guide following a general curved course without
abrupt bends or friction, a rib n preventing the cord being drawn from the
end of the said curved face.
While I have shown means for carrying the guide toward the cop to preserve
the contact of the two at the point where the cord passes from the guide it will
be evident that an equivalent would consist in means for carrying the cop against
a guide receiprocating on an immovable support.
Instead of a single thread, the screw may have a second thread as indicated
at y², Fig. 11, so that when one is worn the shoe 52 may be inserted in the
other.
It will be seen that by providing means for uniformly rotating the cop or cop
holder and of varying the throw of the guide so as to reverse the movement of
the guide at a point circumferentially at one end beyond the point at which it
started at the opposite end, I am enabled to build up cops of succeeding rings or
helices laid in regular and uniform succession, so as to build up the cop in
successive layers each like all the others, of the character set forth in my British
Letters Patent No. 6497 of 1892, and that I can secure this result by the adjust-
ment of the traverse of the guide, instead of providing means for varying the
speed relations of the spindle or holder and a guide having uniform traverse,
as heretofore.
I have used the term "helix" in this specification as describing a coil of.
thread which in extending from end to end of the cop is carried more than one
half a turn around the circumference of the cop so that when reversed to form
a reverse helix, the latter will cross the one first laid at some point between the
ends; or if the helix is of sufficient length, at two or more points between the
ends. While, however, the machine as described is especially intended to lay the
thread in crossed helices, the travel of the guide may if required be restricted
so that the thread will be laid in inclined rings extending diagonally from one
end of the cop to the other and not crossed, thereby winding very narrow cops or
packages suitable for sonie purposes.
Heretofore in machines for winding cops of the general character above
described, the guide or member which lays the cord on the package has been
reciprocated by means of a cam. For winding cops of medium or small size,
this construction is effective, but when heavy thread or cord and large cops are
wound many conditions arise which render the use of a cam inexpedient. For
instance in such cases the cams are necessarily large and on account of their
weight cannot be driven at the high speed sometimes required while a separate
cam is required for each length of cop or package wound:
It will be seen that in the above described machine, I dispense with the use of
a cam and operate the guide by devices comparatively small in size, light in
weight and capable of winding cops of different lengths.
In the modified form of apparatus illustrated in Figs. 12 to 23, I do not adjust
the guide so as to add or subtract slightly from, its traverse in order to lay the
helices in succession, but I increase or decrease the speed of the reciprocation
of the guide as in the machine of British Letters Patent No. 6381 of 1893, but
through the medium of improved appliances.
In said figures, Fig. 12 is a front elevation of a machine embodying certain
modifications; Fig. 13 is an end elevation of Fig. 12; Fig. 14, an elevation,

view of the parts at the right of Fig. 14; Fig. 18 is à section on the line 7-7,
Fig. 17, looking in the direction of the arrow; Fig. 19 is an enlarged sectional

Fig. 21 is a section of a modified expansion pulley; Fig. 22 is a face view thereof;
and Fig. 23 is an edge view thereof.
In this construction, a transverse pin 23, Fig. 17, connects the clutch member 53
with a rod 22 which extends through the hollow end of the screw D and projects
beyond the same.
The rod 22 is connected with the rode by means of the arm H having a fork
fitting an annular groove in the collar at the end of the rod 22. This latter rod
is free at all times to rotate with the screw D but can be shifted longitudinally
by means of the rod c to throw the clutch from engagement with one gear into
engagement with the other.
There are two parts G, G, which act as detents in one position, but when lifted
release the shifting devices. Each part G engages a contact piece g which is
adjustable in position on the rod c.
It is obvious that any friction between the ears a of the guide I and the shifter
rod c, or the jar of the machine might disengage the clutch before the proper
time for such disengagement, and for this reason I provide positively acting
detents. The latter are pivoted to the supports 24 which are adjustable in
position on the guide rod e. Each of these detents has a shoulder 4, adapted to
a corresponding shoulder on the contact piece g and is depressed by the spring t,
so that the two shoulders engage in one position of the parts.
The extremity of each detent is beveled, and the guide I provided with suitable
projections 70, 70, adapted to engage with each detent at each end of the traverse,
to lift the detent and allow the rod to be shifted directly or indirectly to reverse
the motion of the screw.
With a clutch mechanism of this description, in which the direction of rotation
of one member is reversed by throwing it alternately from engagement with one,
into engagement with another of two other oppositely rotating members, it is
essential that one side of the clutch be disengaged, before the other side is
engaged. There is, in consequence, during the operation of reversing the motion
of the first member, a momentary period during which it is unconnected with the
driving mechanism and hence is neutral, being inoperative to drive the parts
to which it is connected.
If the guide I ran at very high speed and any projection from the guide struck
directly a contact piece upon the rod c, there might be sufficient momentum in
the shifting parts, to carry the clutch from one gear into engagement with the
other, but this is not positive and sure, especially at slow speeds, and I therefore
provide an independent means for shifting the parts arranged to operate when the
detents G G are lifted. Thus I arrange on the rod c, adjacent to the contact
pieces gg, springs 42, 42, adapted to be compressed by the ears a as the guide I
.approaches either end of the traverse.
By this means, sufficient power is stored up prior to each movement of the
clutch to throw the latter positively into engagement with one gear, after it has
been disengaged from the other, and this results regardless of the speed of move-
ment of the guide.
In order to vary the length of the cop, I vary the extent of the traverse of the
guide, by shifting the position of the parts 24, g and 42, as before described.
Fig. 14 shows the position of the parts just after the clutch has been thrown
into engagement with the gear 32. One of the projections 70 of the guide I,
has lifted the left hand detent G from engagement with the contact piece g;
the ear a, pressing against the contact piece after compressing the spring 42
has forced the clutch out of engagement with the gear 31, and the

page_text: spring 42, compressed as stated, has carried the clutch into engage-
ment with the gear 32. The guide, as shown is now moving toward
the right. As it approaches the opposite end of its traverse it will
compress the spring 42, one of the projections 70 will lift the detent G,
the ear a will strike the stop g and force the clutch out of engagement with the
gear 32, the compressed spring 42 completing and insuring the instant move-
ment of the clutch, throwing it into engagement with the gear 31. As the rod c
moves to the right, the shoulder 3 of the contact piece g at the left hand end of
the traverse will have passed the corresponding shoulder 4 on the detent G,
allowing the latter to drop into position to prevent the movement of the rod e to
the left until the contact is again raised by the approaching guide.
In order to prevent the engaging parts of the clutch device from becoming
clogged and ineffective the clutch sleeve 53 is covered by a band 53", Figs. 14
and 17.
I show in Figs, 5, 8, 17 and 18 an improved device whereby the guide is
restrained from returning to the spindle after it has been carried outward. In
said figure there is a bearing bar Q, pivoted or otherwise secured to the frame A,
and shown as curved concentrically with the axis of the frame F and resting upon
a lug 75 of the frame F. Pivoted to the frame is a wedge l' bearing upon the
bar with its curved edge and weighted to maintain contact therewith, the con-
struction being such that the frame F can move away from the spindle in the
direction of the arrow Fig. 18, without material resistance, but is prevented by
the wedge from returning. By pressing upon a finger 76, however, the wedge
may be lifted to permit the frame to be swung inward when required.
The position of the above parts might be altered without changing the. effect
by connecting the part Q to the frame F and the parts 1', 75 to the main frame,
and it is evident that the wedge could be arranged to bear upon either edge of the
bar Q.
To provide means for positively and accurately regulating the relative move-
ments of the rotating winding spindle and the reciprocating guide, I use
adjustable expansion pulley L', Figs. 13, 19 to 23, of improved structure. Hereto-
fore, expansion pulleys have been used provided with a V-shaped groove, adapted
to a correspondingly shaped V belt. This, while one of the most efficient devices
for accomplishing the desired regulation in speed. is open to the following
objections.
1st. The specially formed V belt is expensive to manufacture, owing to the
fact that it must be accurately formed to uniform cross section.
2nd. Owing to the stiffness of a V section, such a belt is much less flexible
than a flat one, and does not obtain so good a bearing on the pulley.
3rd. The V belt is not available for use on machines that wind heavy material
because it is difficult to obtain leather of sufficient thickness for such heavy
belts as would be needed.
4th. When the expansion pulley is adjusted, it presents a greater or less sur-
face to the felt; depending on whether the two halves are separated or closed
together.
5th. As the leather becomes more pliable from use, and from the oil absorbed,
it sinks more deeply into the pulley thus, changing the pitch line of the pulley
and causing the wind to change.
In my new and improved construction, I overcome these faults, by the use of
an expansion band or ring, whose inner face is fitted to the V groove in the
pulley and having a substantially flat outer face, adapted to receive a flat belt.
By this means, I am enabled to use a thin flexible belt of any desired width,
which will readily adapt itself to the periphery of the pulley, insuring the
maximum surface of contact, and of sufficient width to transmit great power.
As shown in Figs. 19 and 20, the parts 60, 61 are the parts of the expansion
pulley having beveled edges adapted to the beveled inner face of the split ring
or band 73, from one end of which a pin 76 projects inward into a hole in a

page_text: pin 77, extending loosely through both parts of the expansion pulley. The
pin 76 must be so located relative to the split in the band, that as the pulley rotates,
the band is drawn by said pin, rather than pushed, so that the belt will tend to
press the band into its groove. Were the pin 76 so located that the rotation of
the pulley tended to push the band, instead of pull it, the band would be dis-
tended, with danger of fracture, especially if made of cast metal which is the
least expensive method of manufacture and the band would be pushed away from
the pulley, thereby changing its pitch line and the ultimate effect on the winding.
In the construction shown in Figs. 19 and 20, the disk 60 is clamped to the
shaft which may or may not be the winding spindle, and the disk 61, slides upon
the shaft which is provided with a screw thread receiving an adjusting nut 74,
the latter having a slot s, and binding screw 79, whereby it may be clamped firmly
in position upon the shaft.
In the construction shown in Figs. 21, 22 and 23, the hub 63 of the fixed disk 60,
is threaded, as shown, and the disk 61 slides upon said hub and is provided with
an internally threaded collar 74" which has a slots and binding screw 79, and
serves the purpose of the nut 74, Fig. 19. In the construction of Figs. 21, 22
and 23, the pin 77 of Fig. 19, could not be used as, in adjusting, one disk is turned
independently of the other and the pin 76 is therefore extended into a slot 78
in the disk 60.
The belt L, Figs. 12 and 13 passes from the expansion pulley L' to a pulley L³,
the shaft of which is carried by a frame K swinging about the shaft 26 as a centre
and provided with a gear wheel 8, meshing with a gear wheel 9, on the shaft of
the pulley L2, the frame K having a weight w² connected therewith to maintain
the belt taut.
While I have described and shown the band 73 upon the expansion pulley, as
consisting of a single split ring it may consist of sections of a ring each secured
preferably at one end, so as to turn with the disks of the pulley.
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:
-
1. The combination in a winding machine, of a rotating holder and recipro-
cating guide and means whereby the traverse of the guide may be changed to lay
the cord between the ends of the cop with one or more turns or parts of a turn,
substantially as set forth.
2. The combination in a winding machine of a rotating holder, reciprocating
guide, means for varying the traverse of the guide to lay the cord in helices each
having one, two or more turns, or parts of turns, and means for slightly varying
the traverse to lay the helices circumferentially in succession parallel to each
other, substantially as set forth.
3. The combination with a rotating cop holder, of a frame movable to and
from said holder, a guide carried by said frame, and devices such as the screw D
and its appurtenances also carried by said frame for operating the guide, sub-
stantially as set forth.
4. A winding machine provided with a rotating cop holder, a frame movable to
and from the holder, a guide reciprocating on said frame, guide operating devices
such as the screw D and its appurtenances carried by the frame, and means for
preserving the contact of the guide and the cop, substantially as set forth.
5. The combination with the guide of a winding machine, of means for moving
