Improvements in Machines for Winding Yarn, Thread, Cord,
and other Material.
I, JOSEPH ROBERT LEESON, of 226, Devonshire Street, Boston, Suffolk County,
State of Massachusetts, United States of America, Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to machines for winding from rotating supplies, and the
object of the invention is to provide a machine which is adapted to take yarn,
thread, cord or other material from several cops that have already been wound
in multiple, and so re-wind it that the resultant product shall combine all the
strands contained in the multiple cops, so that each strand may be continuous
throughout the product, and all the strands lie flat and substantially parallel to
each other. In order to do this, it is necessary to unroll the yarn or other material
from the supplying multiple cops, for, if it were drawn over the end of the cops
or package as is done with single yarn, the product would be twisted and conse-
quently the strands would lie neither flat nor parallel.
As the yarn used for the supply has been already wound in multiple, the weak
spots in the separate strands have been eliminated; and they have been wound
under such uniform tension that when the multiple strand is drawn from the
supply there is little danger of breaking the single strands composing them. It
follows therefore that if each multiple strand is wound without breaking, it is
safe to assume that the separate strands composing the multiple remain intact.
In order, then, that each multiple strand shall be continuous throughout the
product or package, it is important, first, to insure that no undue strain is
brought upon the various bodies of multiple strands; second, in case one of these
bodies of multiple strands breaks, to provide means whereby the winding shall be
immediately stopped so that the broken ends shall not run into the product or
package being wound.
In order to wind from an unrolling supply, it is necessary to neutralize the
effects of the momentum and inertia of the supplies. The winding spindle on
which the product or package is being formed must be started with a gradual
acceleration until the full speed is attained, for if it is started suddenly, the
inertia of the supply will break the yarn. In order to stop the winding, the
rotating supplies must stop coincidently with the product cop or a very little
later. If the supplies stop ever so little before the winding spindle of the product,
"and
the yarns will break; if the supplies stop too late, they will-over-run
there will be slack yarn to be taken up by hand or otherwise before the machine
can be started. Should the winding spindle be started before this slack is taken
up the winding spindle will acquire its full speed before the supplies are started
and the inertia of the latter is so great that when the slack yarn tightens it
breaks before the supplies can yield.
It is with the.object of overcoming these and other difficulties that this inven-

page_text: tion is made and it consists in the various features of construction and arrange-
ment of parts having the general mode of operation substantially as herein
specified,
In the accompanying drawings, there is illustrated a preferred embodiment

In the drawings. A represents a winding machine on which the product or
cop is to be made, and this machine is shown. as attached to a column B. It is
not deemed necessary to describe in detail the construction and arrangement of
the winding machine itself, as that may vary but comprises essentially, so far as
the present invention is concerned, a rotating spindle A¹ and a swinging frame R
carrying a traversing thread guide R' having an eye or eyes and arranged to
travel back and forth in front of the winding spindle in a manner well under-
stood in this class of winding machines."
Attached to the column B is a frame D which supports the operating mechanism
and mounted on this frame are the cops S of multiple yarn used for the supply,
these cops being held on supply holders S, and there may be any desired number
of these supplies, three being shown in the present instance.
These supply holders S₁, shown enlarged in Figs. 5 and 6, consist essentially of
a sleeve integral with a brake disk c and concentrically attached to a bushing d
which rotates on a pin or spindle supported in the frame D. This pin or
spindle is grooved longitudinally to receive absorbent material that shall
retain oil to maintain the lubrication of the supply holder and there is a screw a²
at its outer end the head of which serves. to keep the bushing on the spindle.
The bushing has an external screw thread at its outer end adapted to receive
the similar internal threads in the tapered plug e. The supply holder sleeve b
has, at its end, inner bearing faces corresponding to the taper face of the pluge,
and it is also provided with longitudinal slots 1 cut in its shell, so that, as the pluge
is screwed onto the bushing d, the ends of the sleeve are expanded. The plug e is
provided with a suitable handle el whereby it may be readily operated. On the
hub of the brake wheel there is an inclined or tapered portion f which serves
to center tubes that are larger than the body of the sleeve. The supply cop on
its tube is pushed onto the supply holder S₁ until the end of the cop tube bears
on the taper and the end of the sleeve is then expanded by adjusting the
plug e until it binds the cop tube sufficiently to hold it firmly on the sleeve and
to prevent it from slipping thereon. It will be seen that this. construction is
simple, readily adjusted, and serves to securely support the supply cops and the
brake wheel in connection with the brake devices hereinafter described controls
the movements of the cops.
While the brake wheel controls the starting and stopping of the supply cops,
it is desirable to provide them with tension devices which shall automatically
decrease to adjust themselves to the increased speed of the yarn due to the
increasing diameter of the product or winding.cop C on the winding spindle A¹..
Mounted in the frame D is a pin or shaft on which is pivoted a frame. having
a lug and to this frame is attached a plate h which bears upon the top of the

page_text: supply cop. These plates are so, located relative to the supply cops that when
the latter are first placed in position and are full of yarn, the plates are hori-
zontal and exert their maximum pressure on the top of the cops.
As the yarn is
unrolled from the cops S they decrease in diameter and the plates fall exerting
a constantly decreasing pressure or tension on the cops. The weight of the
plates alone may be sufficient to produce the necessary tension when the yarn
is running at high speed, but it is desirable to increase the weight to produce
the necessary tension when the yarn is running more slowly, and to do this a
weight is pivotally mounted on the pink and is provided at its upper part with
a lug m and the screw passing through the lug impinges on the corresponding
lug on the frame and by turning the screw the weight may be raised or
lowered thereby increasing or diminishing its effect on the plate h. This simple
construction provides a satisfactory tension device for the unrolling cops in which
the tension is automatically. decreased to adjust itself to the increasing speed of
the yarn as it is unrolled from the cops and wound upon the cop on the winding
spindle A which latter may have a uniform speed of rotation.
From the various supply holders S' the multipled yarns, pass, to the guide
wheels loosely mounted on a shaft supported in an extension 1 of the
frame D. Sometimes the strands.will become displaced from the periphery of the
wheels which are shown as circular in cross section and if so they are liable
to break and clog the bearings. To prevent this, a guardo is placed on the
hub of each pulley which guard extends over the hub of one of the adjacent
pulleys so as to catch the strands that are displaced and these guards are grooved
on their peripheries so as to prevent the strands from working into the space
between the guard and the adjacent pulley. This feature is further illustrated
in Figs. S and 9..
From the guide wheels the multiple yarns pass over the spoons which are
pivotally supported at p on the frame extension D and the free ends of which
extend over the grooved wheels. Arranged between the spoons and the winding
cop is.a shelf or platform 12 over which the multiple yarns pass to the traversing
guide R, and onto which the threads fall when they become broken and are pre-
vented from being entangled with the devices below the shelf. This shelf is
mounted on the frame D, and its extension D', and mounted on the shelf is a
piece of felt y under which the multiple yarns pass and which tends to keep the
threads from tangling, and if any of them break, to hold them in place on the
shelf 12 ready for piecing. Furthermore, the yarns being wound, attain sufficient-
momentum to throw them out of the eye or eyes when the machine is stopped,
the tension on the yarns sometimes being slight enough to allow this, and the
felt y serves as a secondary tension to overcome the momentum of the winding
strands and maintain the yarns at the eye under sufficient tension to hold them
in place. From the shelf the multiple yarns pass through the eye or eyes of
the traversing guide R and are wound upon a cop C supported on the winding
spindle A of the winding machine.
In the devices for stopping and starting the winding spindle there is a driving
pulley 3 (see Fig. 12) loosely mounted on the driving shaft A2 which is thrown
into connection with said shaft by means of a friction clutch. While various
forms of clutches may be used, there is shown a clutch portion 2, movable longi.
tudinally on the shaft A2 but rotating therewith and which is under the stress
of a spring 2 tending to cause it to engage the driving pulley, and the clutch
is withdrawn from engagement with the pulley by a dog 4 acting on the beveled
flange 9 of the clutch. The part 2 thus by its change of position acts to stop or start
the machine, and I therefore term it the stopping and starting device. The
dog 4 is mounted on a rod 19 supported in the frame of the machine and also
mounted on this rod is a brake 6 arranged to bear upon the brake wheel on
the shaft A2. Connected to the rod 19 is a handle 5 provided with a small plate
or cam 15 and also mounted on the rod 19 is the auxiliary lever 17 provided
with a toe or cam 18. Also mounted on the rod 19 is a spring 25 which tends to

page_text: turn the rod to throw the dog 4 into engagement with the flange 9 of the clutch.
Mounted in connection with the driving shaft A2, and in this instance, on the
hub of the clutch 2, is an inertia wheel S which is adapted to rotate on said hub.
In the hub of the inertia wheel 8 are several grooves 8ª, and in these grooves are
'rolls 9a and the bottoms of these grooves are slantingly related to the periphery
of the clutch hub, rendering the said grooves deeper at one end than at the other
so that when the shaft A2 and the winding spindle rotate in its forward direction,
the rolls bind between the clutch hub and the inertia wheel carrying the latter
with the spindle and shaft. Arranged in connection with each roll 9 is a spring
or similar yielding device 9b which keeps the rolls in contact with the periphery
or the clutch hub and the bottom of the groove in the wheel thus preventing the
rolls from falling away or chattering. The brake wheel 7 is provided with
pins 7 taking into recesses in the hub of the clutch 2. The expansion pulley
shown at the right hand end of Figure 12 is similar to the pulley Gin Figure 5
of my prior British Patent No. 561 of 1896. It is adapted to receive a belt of
triangular cross section, and is capable of adjustment by moving the discs con-
stituting the pulley towards or from one another in order to vary its effective
radius and to so effect-a variation in the ratio of movement between the winding
spindle and the thread guide operating device in a similar manner to the aforesaid
pulley.
With this construction in order to start the machine, assuming the driving
pulley to be rotating, if the clutch were thrown into connection with the pulley
and the machine started abruptly attaining its full speed too suddenly, the multi-
pled yarns not being strong enough to overcome the inertia of the supplies are
liable to break, and by applying the inertia wheel to the clutch, the inertia of the
clutch and wheel is such that the clutch when it is thrown into working position
refuses to act immediately, but slips in the driving pulley, and holds back the
spindle A and shaft A2, which spindle and shaft are integral, causing them..to'
come to the requisite speed with an approximately uniform acceleration. When
the machine stops, the dog 4 being thrown into engagement with the clutch by
the spring 25, the inertia wheel 8 is free to rotate on the hub of the clutch
through the medium of the rolls 9a and thus the stress upon the shaft A² due to
the momentum of the inertia wheel is eliminated, and strain to which the
machine would be subjected if the inertia wheel were rigidly attached to the
shaft or hub is avoided. Futhermore as the clutch 2 is withdrawn from the
driving pulley by the dog 4 simultaneously therewith the brake 6 is applied to the
brake wheel 7, and the shaft A2 and its spindle are immediately stopped, the
brake being sufficient to overcome the momentum of the shaft while the momen-
tum of the inertia wheel does not affect the shaft, as above explained. This
brake and brake-wheel 7 are illustrated in Fig. 14, and it will be seen that
the brake 6 on the shaft 19, is arranged so that when it is applied to the brake
wheel 7, on the shaft A2, the direction of rotation of the brake wheel is such
that the brake being brought in contact with the disk through the medium of
the spring 25, the spring and disk co-act and cause a sort of toggle joint action,
thereby causing the brake to press quickly and tightly against and positively stop
the rotation of the shaft to which the brake wheel is attached, and this is an
important feature, especially in high speed machines, as by this arrangement the
motion of the shaft and its attached spindle can be almost instantly stopped. Thus
with this construction, the machine can be gradually started without danger of
breaking the multipled yarns, and the spindle can be instantly stopped and
the spindle shaft relieved of the momentum of the inertia wheel so that if per-
chance a strand breaks, the spindle can be stopped before the broken end is
wound thereon.
I have designated the wheel 8 as an inertia wheel and by that I mean a wheel
or equivalent. member mounted and connected to the parts so that when the
parts are started to rotate, the inertia of the wheel tends to retard the starting
cand, where as; in the present instances the combined spindle and shaft A, A is

page_text: normally stationary, while the driving pulley may be rotating loosely on the
shaft when the clutch is thrown into working position the pulley has to over-
come not only the inertia of the shaft and clutch but also the inertia of the
wheel; so that the shaft will not attain its full speed as quickly as it would
without the inertia wheel, but the speed will be attained under a substantially
uniform acceleration, and in the present instance would start the supplies rotating
without undue strain. So too the inertia wheel in the present instance is so
mounted on its support or driving member that when that driving member stops,
the wheel can continue its rotation under its momentum without rotating its
supporting member, which in the present instance is the clutch connected to
rotate the shaft A2, and thus the strain upon the shaft by the momentum of the
wheel if it were rigidly attached thereto is removed.
So far, the stopping and starting device has been described only as being
operated by the handle 5, and the automatic stopping device will now be des-
cribed. Mounted on the rod 19 is an arm 24 having at its end a hook 21 and
engaging with this-is a hook 22 mounted on the detent lever E which is pivotally
mounted on the frame of the winding machine in the usual way and which tends
to hold the rod 19 in such a position as to allow the clutch 2 to engage' the
driving wheel, the dog 4 and brake 6 being held under the stress of the spring 25.
When, however, the detent lever E is operated to disengage the hooks 22, 21,
the rod 19 is turned under the influence of the spring, applying the brake 6 and
the dog.4 to operate the clutch and stop the machine. This detent lever E in this
class of winding machines is operated in various ways, as for instance, when the
winding cop or product is full, the frame R, which supports the traversing eye
or eyes R comes in contact with an adjustable screw E mounted on the detent
lever, and other means for operating the detent lever may be used which form
no part of the present invention.
The spoons as above indicated are arranged over the guide pulleys in such
a manner that the multiple strands pass over the spoons, holding them in the
position shown in Fig. 1 during the operation of winding, but if any one of the
multiple strands breaks, the spoon being released from the strain of the strand,
will move upward and by means of its connecting devices, instantly stop the
winding spindle.
The winding spindle A' on which the cop C is placed, is provided with a series
of flutes or corrugations s. Pivotally connected to the detent lever E is a series of
stopping leverst and one of these levers is attached to each one of the spoons ?
by means of rods or wires 14 which rods or wires are provided with an extensible
connection F, Figs. 1 and 11, so that they can be properly adjusted. The arrange-
ment of these members is such that when the spoons are held down in their
normal position by the strands, the levers are held up away from the corruga-
tions s on the spindle, but if any one of the strand breaks or becomes disarranged
allowing the spoon to fly upward, the corresponding levert falls, and by engag
ing with the revolving corrugations & forces the detent lever E back releasing the
arm 24 and allowing the stopping mechanism to operate.
.
Mounted on the frame D is an arm 27 carrying a pin 23 which extends under
the stopping levers t so that when the arm 27 is raised, it carries with it the
levers t, and through the wires 14, depresses the spoons p into the position ready
to. thread the machine or re-adjust the strands that have become broken or dis-
arranged. Also mounted on the frame D is a lever 16 which is connected to the
arm 27 by the spring 28, and this lever is provided with an indentation at its
free end When this lever 16 is down as indicated by dotted lines, Fig. 2, the
end of the lever locks the cam or plate 15 and prevents the handle 5 from being
moved forward to start the machine, and in order to start, the auxiliary lever 17
is lifted and the toe or cam 18 connected to said auxiliary lever engaging the end
of the lever 16 raises it to the position shown in full lines, Fig. 2.
The lever 17. is free, to turn on the rod-19, and the hub of the lever 17. has a
cam 18, formed on its edge for the purpose of raising the lever 16, for oper
operating
1.

page_text: the brakes on the supply holders S. Working in conjunction with the cam 18,
is a cam plate 15, attached to the handle 5. Prior to starting the winding the
lever 17 is in its lowermost position 171 indicated in dotted lines, Fig. 2, with
the free end of the lever 16, resting on the cam 18, also shown in dotted lines,
Fig. 2. The cam plate 15, is so attached to the handle 5, that when the latter is
disengaged from the detent lever E, it is so related to the lever 16, that the
handle 5, cannot be moved to start the winding until the lever 16 is lifted out of
its way. In order to do this the lever 17 is raised from its dotted position 17',
to the position indicated in full lines, Fig. 2, its cam 18, raising the free end
of the lever 16, and when the lever 17, and the lever 16, have reached the upper
position, indicated by the full lines in Fig. 2, the toe of the cam 18, engages
the indentation 20, at the extremity of the lever 16, causing the lever 17, to be
sustained in its upper or full line position. When the handle 5 is moved to
release the clutch 2, and allow it to be operatively connected with the pulley 8,
the cam plate 15, raises the free end of lever 16, allowing the toe of the cam 18,
to be disengaged from the indentation 20, so that the lever 17 drops back into its
lowermost or dotted position.
Rigidly connected with the handle 5 is an arm 26 carrying a rod 26ª, which is
adapted to act upon the arm 27, thereby moving the pin 23 away from the
levers tt leaving them free to fall.
When the stopping levers t, or anyone of them, come in contact with the
corrugationss, as before stated, the detent lever is moved backward, disengaging
the detents or hooks 21 and 22. The arm 26 moving in conjunction with the
rod 19, under the action of the spring 25, rises, carrying with it the pin 26", thus
allowing the spring 28 to act, to raise the arm 27 and with it the pin 23. The
latter coming into contact with the stopping levers & raises them, thus depressing
the spoons as above stated. The position of the arm 20 is so adjusted that the
winding spindle starts before the pin 23 is sufficiently depressed to let the levers t
come in contact with the corrugations s, and before this happens, the tension on the
strands is sufficient to operate through the spoons 7 and, sustain the levers tin
position away from the corrugations.
In order to stop the supplies S and prevent them from overrunning when the
winding spindle is stopped, brakes are arranged to bear on the brake wheels c
of the supply holders, and may be attached to levers 10 which are under the
stress of the springs 11 tending to apply the brakes. The brakes are withdrawn
by means of a rod 12 connected to the lever 16 and provided with collars 13
engaging the free ends of the brake levers. When the machine is running as
shown in Fig. 1, the lever 16.rests upon the cam 15, and the rod 12 by its collars
133 holds the brakes y out of contact with their brake wheels, but as soon as the
stopping device is operated as above described, the lever 16 falls to the position
shown in dotted lines, Fig. 2, and the rod 12 is moved downward allowing the
springs 11 to quickly apply the brakes g to the supply holders.
It will thus be seen that each brake g is independently operated by its
spring 11, to engage its corresponding brake wheel controlling its particular
supply, and that all the brakes are released simultaneously when the rod 12, is
moved upward by the lever 16. This arrangement is important in high speed
machines, as it is almost impossible to arrange a series of brakes controlled by a
single means and applied to a series of devices, to have them operate simul-
taneously and quickly to stop the devices, as slight variations in the form or.
arrangement of the parts will prevent a uniform pressure being applied to all
the devices, while with my arrangement each supply receives the benefit of the
pressure of an independent device applied to its particular brake and is stopped
instantly.
It will thus be seen that if any one of the multiple strands breaks the spoon p
rises, the stopping levert falls and engages one of the corrugations s, the detent
lever is moved releasing the arm 24 and allowing the springs 25 to apply the
brake 6 and disconnect the clutch 2 by means of the dog 4, and the balance wheel

page_text: moves on without affecting the winding spindle, while the spring 28 operates
upon the arm 27 to lift the stopping levers by the rod 23, and set the spoons in
position for threading, and the lever 16 falls, moving downward the rod 12;
allowing the brakes to be applied to the supplies, and thus the supplies are
stopped almost simultaneously with the stopping of a winding spindle which,
as before stated, is practically instantaneous.
As it is impossible to obtain absolute uniformity of tension or regularity of
rotation on the part of the supplies, and as these irregularities affect the stopping.
levers and their connections so that sometimes yielding to the recurrent slacking
of the threads, the spoons ? commence to vibrate and the levers t acting in sym-
pathy with them and these vibrations being accentuated by the momentum of
the vibrating members, one or more of the levers may be thrown in contact will
the corrugations's and cause the machine to stop. This is remedied by interposing.
between the supplies S and the spoons a compensator or yarn tightener e
shown in the form of a light wire bail pivoted to the frame D and its end which
is free to vibrate bearing on the strands, taking up any slack that may occur and
yielding with a temporary excess of tension over the normal, so that the objec-
tions just stated are overcome.
In Figs. 15 and 16 is shown a modified form of guide R. If a large number
of strands are run through one eye or channel, they will not lie flat, but those
on the edges of the body of strands being wound will roll on top of the others.
This is especially true of the strands on the side of the body towards which the
traversing guide R' moves, as it travels back and forth. But up to a certain-
number of strands there is no such trouble, so that if the larger body of yarns
can be subdivided into smaller bodies, and each of these be provided with a
separate guide or eye, the final product will be better laid on the product cop,
than if all the strands were drawn through a single eye. Fig. 1 shows the
machine provided with a single eye, while Figs. 15 and 16 show a guide with a
series of eyes and slow the method of attachment to the machine. The guide R¹
has two pins or studs in it, adapted to slots in the eye piece r, so that the
latter can be readily removed when desired.
In order that the essence and scope of the invention may be better understood,
the sequence of operations to be performed from the time-the cops of multipled
yarns are placed on their supply holders S¹ to the time the product cop C is
finished, will be described.
When not in operation the parts of the machine should be in the following
described positions.
The handle 5 is in its extreme back position as indicated in Fig. 2; the dog 4.
(Fig. 12) has withdrawn the clutch 2 from the pulley 3 so as to dissever the active
connection between the pulley and the winding spindle: The driving pulley 3.
is constantly rotating. The arm 26 holds the pin 26 in its upper position,
thereby allowing the spring 28 to act on the arm 27, and through the pin 23
elevate the levers t, thus depressing the spoons-p and leaving them in position to.
thread, as heretofore described.
•
The auxiliary lever 17 is down, as shown by the dotted lines in Fig. 2. and
the lever 16 is also down as indicated by the dotted lines, so that the collars 13.
are withdrawn from the levers 10 and allow the brakes g to act on the brake.
wheels e of the supply holders S', to prevent their rotation. The tension plates h.
are at their lowest points, resting on the supply holder sleeves b.
To prepare the machine for winding, the several cops of multipled yarns are
placed upon their supply holders, each tension plate being raised to admit. its
cop. The cops are pushed onto their supply holders until the end- of the cop:
tube reaches, and if larger than the sleeve b centers itself on, the tapered por-
tion of the supply. holder. The plug e is then forced into the sleeve expand-
ing the slotted end thereof, fastening the supply to its holder as heretofore
described.
The supplies, having been placed in position, and properly secured, the

page_text: handle 17 is raised and the toe 18 engages with the end of the lever 16 raising
it sufficiently to withdraw the brakes g from their supply holders, leaving them
free to revolve. The end of the toe 18 engages with the notch 20 in the end of
the lever 16 and is held up, the two levers thereby co-operating to restrain the
to be moved forward.
brakes from the supply holders, and permit the lever
The supplies being now free to rotate, the various bodies of multiple yarns
are drawn forward, under the compensators a, around the pulleys o. over the
spoons, under the felt y and through the eye or eyes of the thread guide R¹.
The ends are then so wrapped around the cop tube on the winding spindle as to
hold them fast when the winding is started. The operative, after making sure
that there is no slack between the supplies S and the pulleys o, moves the
lever 5 forward, carrying with it the plate 15, which further raises the lever 16
and releases 17 allowing it to fall back. The lever 5 carries with it the arms 24
and 26, and with the latter the pin 26. Before this pin touches the lever 27, the
brake 6 is withdrawn from the brake wheel 7, leaving the winding spindle free to
rotate, and the dog 4 is withdrawn from the flange 9, thereby allowing the
clutch 2 to contact with the pulley 3. The tendency of the clutch is to imme-
diately engage with the pulley 3, but it is held back by the inertia of the wheel 8
until the latter gets under way and with it gradually attains the full speed of
the driving pulley 3.
After the winding has started and the yarns being wound are under sufficient
tension to maintain the levers in position away from the corrugations s, the
pin 26 depresses the lever 27, causing the pin 23 to recede from the levers t, so
that, when any one of the supplies breaks or becomes exhausted, the lever which
it controls, can drop and cause the machine to stop as described. The handle 5
is held in its forward position by means of the detent lever E through the
medium of the lock pins 21 and 22 until such time as the detent disengages the
lever 24, thereby allowing the stopping devices to act.
-
Suppose now that one of the strands of multiple yarn breaks, or that its
supply has become exhausted. As soon as the end thereof passes from between
the tension plate h and the supply cop S (or its tube, if the yarn has run out) the
tension on the yarn ceases and the spoon, over which it passes, flies up causing
the corresponding levert to drop and engage with the revolving corrugations
and operate to stop the, machine. In order to unite the broken ends or tie in
the end of a new supply, the same sequence of operations is to be followed as in
the original starting. The supply brakes must first be released and the yarn run
under the compensator, around the wheel over the spoon p, under the felt y
and tied to the broken end on the supply cop, and the winding started.
As the cop increases in diameter, the swinging frame R recedes from the
product cop, carrying with it the traversing guide R¹, until the cop attains its
proper diameter, when it comes in contact with the adjusting screw E thereby
forcing back the detent lever E and causing the machine to stop as described. The
product cop is then removed and a new one started.
The products are intended to be used in spinning, weaving, knitting, etc.
Further they may be used for binders' twine, for ropes, and in fact all sorts
of cordage broadly speaking, the products being in a saleable condition as well
as being in a proper condition for use in other processes, such as spinning,
weaving etc., and the machines are not intended to be made and sold for use in
any particular branch of the art, but may be used in all branches.
As to the nature of the materials other than varn and thread, the machines
may be used for winding wire, asbestos, jute and hemp ropes and cords, and in
