Improvements relating to the Winding of Thread or Yarn, and to
Machines therefor.
I, EUGENE STOWELL Boss, of Willimantic, in the County of Windham, and
State of Connecticut, 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:---
My invention relates to improvements in machines for automatically winding
successive cops or sets of cops upon cores and for automatically discharging the
wound cops.
In the accompanying drawings, Figure 1 is a view of the machine in front
elevation, showing one set of cop winding and discharging mechanisms in
position, it being understood that in practice several such sets may be arranged
side by side, mounted in the same general frame, and driven by a common
driving shaft. Fig. 2 is a view in end elevation. Fig. 3 is an enlarged view,
partly in end elevation and partly in section, of the operative parts, exclusive of
the drive shaft. Fig. 4 is a top plan view of the same. Fig. 5 is a partial front
view of the same. Fig. 6 is a partial rear view of the same. Fig. 7 is a vertical
section taken in the plane of line 7-7 of Fig. 3, showing a part of the operating
mechanism in front elevation and a part in section. Fig. 8 is a transverse
section through the master cam-cylinder, showing the connection of the actuating-
spring with the cylinder and the shaft on which the cylinder is mounted; and
Figs. 9, 10, and 11 show in detail the several positions which the cop-receiver
and core-reservoir assume with respect to the winding-spindle.
Figure 12 is a detail top or plan view showing the adaptation of my invention
in part to a rotary table.
Figure 13 is a detail end view of the same showing the cutters located in
position away from the spindle.
Figure 14 is a like view showing the cutters in engagement with the cops.
Figure 15 is a detail view in central section through the parts on a line
passing through the axis of the winding and the cam spindles.
Figure 16 is a detail view of a tube on which a plural number of cops are
wound in the operation of the within described machine, this view illustrating
the manner of fastening the several ends of the thread in the beginning of the
operation of winding.
Figure 17 is a detail view showing a plural number of cops at an early state
of the building up of the cops in winding.
Figure 18 is a view of a plural number of completed cops as wound side by
side on the tube and forming what may be termed a mass of thread, although
the several cops are separable by the severing of the tube between two con-
tiguous cops.
Figure 19 is a view in side elevation of the cop.
My invention, in the particular form in which I have at present embodied it

page_text: section G¹ of the receiver is somewhat choked by spring-tongues g', which project
slightly from the inner wall of the receiver to hold the cops, which may have
been forced therein from the rotary section G, in position until they are forced
from the receiver by the thrust of a succeeding set.
The rocking support I has a hub extension through the front of the sup-
porting-frame and has clamped to it an arm, which may be a sector-arm,
by which the support I and parts carried thereby are rocked bodily on the
shaft e through a connecting rod or bar K, controlled by the master cam-
cylinder, as will be hereinafter more particularly described.
On the shaft e there is a sleeve e, which extends from a point within the
housing I through the hub i¹. The sleeve 2 has mounted thereon within the
housing I the thread-guide arm L, the connection of the guide-arm with
the sleeve being made by trunnions 7, projecting radially from the opposite
sides of the sleeve to permit the arm to be vibrated in the plane of the axis
of the sleeve, while at the same time subject to rock with the sleeve.
The thread-guide proper is denoted by 1, (see Fig. 7,) and may be of any
well-known or approved form adapted to distribute the several threads to
positions on the winding-spindle to form the several cops to be wound and subject
to the gradually-increasing size of the cop to be pushed away from the spindle
and through its swinging movement to rock the sleeve e and a trip-dog 1ª³,
carried by the sleeve, to stop the winding-spindle when the cop has reached a
predetermined size, as will hereinafter more particularly appear.
The sleeve e has the trip-dog 12 fixed to it at within the housing I, and it
also has fixed thereto exterior to the housing I an arm for sustaining a
weight to counterbalance the dog and give the thread-guide the desired
pressure against the periphery of the cop being wound.
The shaft e has fixed to rotate therewith a disk E', the inclined face of which
bears against the guide-arm support and serves as the shaft e rotates to impart a
vibratory movement to the thread-guide in a direction transverse to that in which
the thread is fed to lay the thread obliquely on the periphery of the cop
being wound.
The part which I have chosen to designate as the master cam-cylinder" is
denoted by M. It is mounted to rotate on a sleeve m, supported parallel with
the spindle-shaft, and has formed in its exterior curved surface a cam-groove
consisting of two V-shaped portions m¹ m², separated by a shorter annular
portion m3 and a longer annular portion m. An arm N, mounted on a guide
rod or barn to slide freely along its support parallel with the spindle-shaft,
projects into the cam-groove m¹ m² m³ m² and is controlled in its sliding move-
ment by said cam-groove as the cylinder M is rotated. The arm N also embraces
the winding-spindle holder between two abutments and do thereon, as shown
in Fig. 3, so that the movement of the arm N under the control of the cam-
groove in the cylinder will move the spindle-holder, and hence the spindle D.
longitudinally forward and backward as the arm travels along the V-shaped
portions of the cam-groove.
The cam-cylinder M is further provided with a cam-groove in its front end
for operating the bar K, hereinabove referred to, to rock the cop-receiver and
core-reservoir back and forth to present the receiver and a core alternately in
front of the winding-spindle. The said cam-groove consists of three annular
portions, denoted, respectively by kk, and intermediate straight portions,
denoted by 3. (See Fig. 7.) This cam-groove receives a laterally-projecting
roller on the bar K, and as the said roller travels along the groove during
the rotary movement of the cylinder imparts to the bar K, and hence to the
sector-arm, with which the bar K engages by means of rack teeth on its
under side, a positively-reciprocating movement to present a core to the spindle
and a secondary reciprocating movement to bring the cutters out of and into
engagement with the core to subdivide it. The operating-bar K has one end

page_text: At
and worm f and will continue its rotary movement until the belt has been
entirely removed from the drive-pulley. The belt will remain wholly on
the drive-pulley f and the winding-spindle be prevented from a rotary move-
ment while the cylinder M is completing three-fourths of a rotation, more or
less--that is, while the releasing-tappet is being carried from its position
shown in Fig. 7 to a position to lift the retaining pawl Q and again release
the shaft P. During this two-thirds rotation of the cylinder M, more or less,
the two V-shaped portions m² m² and the intermediate annular portion m3 of the
cam-groove in the curved face of the cylinder will have operated upon the
spindle-holder d with the following results: The spindle, with the wound cops
thereon, will have been thrust into the rotary section G of the cop-receiver and
withdrawn from the same, leaving the cops therein. This will have been
accomplished by the V-shaped portion m¹ of the cam-groove. While this has
been taking place the roller on the operating-bar K has been travelling along
the circular portion of the cam-groove in the front end of the cylinder M
and has not disturbed the position of the cop-receiver relatively to the winding-
spindle. At this point, however, and while the spindle-holder d, and hence the
spindle, are held in the normal position by the engagement of the annular
portion m3 of the cam-groove with the armi on the spindle-holder, the bar K
is forced to the left by the straight or tangential portion of the groove in the
end of the cylinder, and the support I. and hence the cop-receiver and the core-
reservoir, are rocked to the left, bringing the core at the bottom of the reservoir
into alinement with the spindle. The core-reservoir is held in this position by
the engagement of the circular portion of the cam-groove with the roller .
while the V-shaped portion m² of the cam-groove in the curved surface of the
cylinder imparts to the spindle a second forward-and-return movement—a for-
ward movement to enter a core and a return movement with the core thereon.
this moment the retaining-pawl Q is released by the tappet and the shaft P
turns around until it is stopped by the engagement of the second retaining-
pawl Q with the abutment 3. This partial rotation of the shaft P, through the
medium of the cam-groove in the disk p, will operate the belt-shifter to shift
the belt into position partly on each of the drive-pulleys f and f³, and will
thereby start the rotation of the winding-spindle, while the rotation of the
master cam-cylinder will be continued. The portion m of the cam-groove in the
curved surface of the cylinder being annular, the position of the spindle will not
be further affected. The straight portion of the cam-groove in the end of
the cylinder will, through the operating-bar K, rock the support I over toward
the right while the winding of a new set of cops is being started, the threads from
the previously-wound set leading from within the rotary section G of the
receiver out around the core on which the new set is being wound and the said
previously-wound, cops being rotated in the section G at the same rate at which
the winding-spindle is rotated. The rocking movement of the support I will be
continued by the portion of the cam-groove until it has brought the cutters ()
into engagement with the core to sever it and the threads between the cops,
and the short circular portion of the groove serves to hold the cutters there a
little time, when the following straight portion of the groove serves to rock
the support I a short distance back to the left to move the cutters out of engage-
ment with the cores and bring the section G of the receiver in alinement with
the spindle ready to receive the wound cops. At this moment the tappet g²
releases the second retaining-pawl Q' and the shaft P' completes its rotation, being
stopped by the nose of the trip-dog 12. This movement of the shaft P operates
the belt-shifter, throwing it wholly onto the pulley f, and the operation of
winding and discharging the cops is ready to be repeated in the manner above
described.
In the form of the invention as illustrated in Figures 12 to 15 inclusive the
cops are built up on the core and the core separated in a manner similar to
that herein before described, the core, however, being placed on and removed

page_text: by means of the cutter as herein before described, this severing of the core also
cutting the threads which have been wrapped about the core as a preliminary
step in the winding operation. Each thread of the bunch when secured to the
core is subsequently wound into a cop as shown.
