page_text: behind that of the revolution of the gear 2. Thus as shown in Fig. 1, the gear 2
is an annular gear sliding round but having a frictional contact with a disc 4,
on the shaft b said gear 2 having an interval gear 5, which engages with a
pinion 6 turning upon a stud on the disc 4. Upon the pinion 6 are studs 7 in
position to make contact with the end of a stationary arm 8 so that as the disc 4
revolves, carrying with it frictionally the gear 2, (if the shaft b is the driving
shaft, or as the gear 2 revolves and carries with it the shaft b, if the shaft a
is the driving shaft) then as a pin or stud 7 makes contact with the arm 8 a
partial revolution is imparted to the pinion 6, so that at each revolution of the
shaft the pinion is moved slightly, moving the ring gear 2 which is thus moved
first by the disc 4 and then additionally by the pinion 6 so as to complete its
revolution slightly in advance or slightly back of that of the shaft b.
Use is made of adjustable devices to vary the said movement which may be
constructed in different ways, a most effective form being illustrated in the
remaining figures of the drawings, but most clearly in the skeleton view Fig. 2.
In this view a illustrates the driving shaft, the shaft carrying the cam e which
imparts motion to the thread guides c, through the medium of the cam groove 9 and
pin 10 on the carriage 17 of said guide. The gear wheel 2 is mounted to turn
independently upon the shaft and has an annular flange with a gear 5, that
meshes with the pinion 14 upon a shaft 13, carried by a yoke 12 on the end of
the shaft b, and a friction wheel or disc 15 is mounted to slide on but turn with the
shaft 13, with its edge frictionally in contact with a stationary friction plate 16. If
the wheel 15 is set directly opposite the axis of the shaft b, the gears 2 and the
shaft bare turned together the same as if the gear was fixed permanently to said
shaft, if however the friction wheel be set to one side or the other of the centre,
as shown in full and dotted lines, Fig. 2, then in that case the rotation of the gear 2
will cause the wheel 15 to travel in a circular path on the bearing 16, and a slow
rotary motion will be imparted to the shaft 13, and its pinion 14, which will
cause the rotary motion imparted to the shaft to be slightly greater or slightly
less than that imparted to the gear 2 accordingly as the wheel 15 is set upon one
side or other of the axial line of the shaft b.
It will be evident that by the adjustment of the wheel 15 it is possible to vary
the extent of the difference between the motion of the gear 2, and that of the shaft b
to any extent desired, so as to regulate these movements with the utmost nicety.
Any suitable means may be employed for shifting the wheel 15 for instance a screw
shaft having a knob Figure 5.
q
The carriage 17 carrying the guide c slides upon guides 20 and the holder for the
bobbin, spool, or tube, consists of heads 21, 22, Fig 3, adapted to enter the ends of
the cop tube the head 21 being upon the shaft a while the head 22 is upon a
sliding rod 23, the said head 22 turning freely on the end of said rod. D is a
lever to move the rod to permit the heads to be separated to insert or withdraw the
cop tube.
The driving pulley 24 turns loosely upon the shaft a but may be clutched thereto.
As shown the said wheel 24, forms one part of a clutch J, the other part of which
is a tapering disc 25 mounted so as to slide on but turn with the shaft a and fitting
an opening in the wheel 24, a spring 27 tending to throw the clutch wheel 25, into
contact with the wheel 24 so that the two will turn together. A pin 28 has an
inclined end that enters a groove in a hub 26 of the wheel 25, so that when the pin
is forced towards the shaft a, its bevel side will make contact with one side of the
groove 26, and will carry the wheel 25 away from the pulley 24.
The pin is elevated and depressed by means of a lever 29.
As the thread guide c bears against the surface of the cop at all times it must
slide outward with the latter as the size of the cop increases and connections
intervene between the thread guide c and the clutch device, whereby the latter is
shifted as soon as the thread guide reaches a determinate position, determined by
the size of the cop that it is desired to wind. Different intermediate connections
may be employed.

page_text: In the construction shown, the thread guide is connected with the clutch lever 29,
Fig. 3, which has a second arm 30, through the slotted end of which extends a
rod 31 threaded at the upper end and having a nut 32, the said rod 31 passing
through suitable guides upon the frame, and having a notch y, Figs. 6 and 7, which
engages a lug 33, upon a lever 34 hung to any suitable portion of the frame.
From a rock shaft 37, Figs. 5 to 7, extends an arm 38 having at the lower end a
bevelled projection 36, Figs. 6, 7 and 8, engaging with a bevelled projection 35
upon the lever 34 so that when the shaft 37 is rocked in one direction the pro-
jections 35 36 are brought together so as to swing outward the lever 34 in the
direction of the arrow Figs. 6 and 8, and an arm 39 Fig. 7, extends from the rock
shaft 37 and has a double bevelled projection 40 which when the carriage 17
supporting the thread guide c is drawn out to a proper extent is struck by a lug 41
upon the said carriage as the carriage slides to one side. It therefore follows that
when the cop is of such a size (which is the predeterminate size) that the
carriage 17 is drawn out sufficiently to cause the lug 41 to make contact with the
lever 39 as the carriage reciprocates, then the end of the lever 39 will be raised,
the rock shaft 37 will be rocked, the lugs 35, 36, will be brought into engagement
so as to swing outward the lever 34 in the direction of its arrow and carry the
lug 33 from engagement with the shoulder y when the rod 31 will be caused to
descend to the position shown in dotted lines Fig. 6 by a spring 42 and the clutch
lever 29 will be rocked so as to lower the pin 28 Fig. 3 and disengage the clutch
and put the machine out of operation.
In order that the machine may be arrested at the proper time according to any
predetermined size of the cop, the arm 39 is adjustable upon the rock shaft 37 by
means of a screw rod 43 Fig. 5, and a thumb nut 44, the threaded portion of the
shaft entering the nut.
In winding cops of elastic threads such as silk, if the tension upon the thread is
maintained uniform throughout the winding, the stricture upon the outer layers
acting upon the elastic body beneath causes the cop to bulge out at the ends.
Means are therefore combined with the winding devices, whereby in regular pro-
portion as the cop increases in diameter, the tension upon the thread is decreased.
Thus in Fig. 4, 45 is a swinging frame pivotted to the frame of the machine at 46, and
having an upper cross bar 50, which bears against a lug 51 on the frame 17 carrying
the thread guide c and an arm 47 extending from the lower part of the frame 45
is connected by a rod 48 with a lever 49 pivotted to a supplemental frame B¹ and
a lug 52 at the upper end of the lever 49, enters a slot in a carriage C sliding upon
a guide rod 53, supported rigidly by the frame B', and a cord s is connected with
the carriage C and passes over a guide wheel 54 and carries a weight W so as to
normally swing the lever 49 in the direction of its arrow and thereby tend to
maintain the frame 45 and its cross bar 50 in contact with the lug 51 on the guide
frame 17 and maintain the -guide c in contact with the face of the cop while
permitting the carriage 17 to slide back in the direction of its arrow as the cop
increases in size.
As the cop increases in size and the frame 45, swings outward, the carriage C
will be moved in the direction of its arrow and this movement of the carriage is
made the means of gradually decreasing the tension.
Thus a shaft 55 of a tension wheel 56 Figs. 4, 10 and 12, which is a plain disc
with a groove at the edge receiving the thread to be wound, is acted upon by a
friction brake in the form of the jaws of a tongs D, the said jaws 57, 58, being
curved to fit the face of the shaft and being pivotted together and extended to
form diverging shanks 59, which extend between lugs 600, 610 on the carriage C.
The lug or pin 610 is hung to a loose frame E and extends through vertical
slots of the carriage C to move vertically thereon, and the said frame is provided with
weights, W, which may be increased or diminished at pleasure so as to vary the
pressure as may be required, according to the different character of threads to be
wound. It is therefore evident that as the top increases in size the carriage 17
moves out in the direction of its arrow and the carriage C, moves in the direction

page_text: of its arrow towards the pivot of the tongs the pressure to bring the shanks
together and the friction upon the shaft 55 of the tension will be decreased in
proportion as the pressure approaches the pivot of the tongs.
As the threads sometimes are knotted or occasionally will get caught so as to
fail to feed, provision is made whereby any such arrest in the movement of the
thread will automatically arrest the action of the machine. Thus the thread passes
over a guide pulley 62 and around a pulley 60, Fig. 4, from which is operated the
stop devices.
As shown, the said pulley 60 is carried by a lever 61, which is
moved in one direction by a spring 63, and which yields in the other direction
whenever the thread is caught. A stud 64 upon the lever 60 engages an arm 65
connected with a rock shaft 66, from which extends an arm 68 in position to
make contact with the inclined lower end of the lever 34, Figs. 4 and 7 and
on the arm 65 is a shoulder w. When the lever 61 is drawn outward in the
direction of its arrow, by the stoppage of the thread, the stud 64 bearing upon
the shoulder w depresses the outer end of the arm 65, rocks the shaft 66, lifts the
arm 68 and forces outward the lower end of the lever 34 so as to remove the
lug 33 from beneath the shoulder y and thereby throw the clutch J, Fig. 3 out of
operation as before described.
Inasmuch as the thread passes from the tension wheel 56 sometimes in a direct
line and sometimes at an angle to the ends of the bobbin and must travel back and
forth from the centre to the ends of the bobbin, there is a variation in the draft or
speed of the feed which increases in proportion as the thread is carried from the centre
towards either end. It has been found that, as a result of this variation, it is
almost impossible to wind some kinds of thread, but the difficulty is obviated by
interposing between the tension device and the bobbin a spring regulator that
will yield as the draft increases and that will take up the thread as the draft
decreases. A preferable form of embodying this regulator is illustrated in the
drawing, Figs. 10 and 11, in which a sleeve 71 turning loosely on the shaft 55, of
the tension wheel, carries an arm 70 having an eye or hook under which the thread
passes, while a spring 72 is connected with the sleeve so as to tend to turn it in the
direction of the arrow a. As the thread passes towards either end of the bobbin
or cop as shown by dotted lines the speed of its draft being thereby increased, the
arm 70 will be lifted increasing the tension upon the spring 72, and affording the
increased quantity of thread required, while as the thread travels back towards
the centre of the cop to the line from either end, the arm will descend and take
up the thread, as will be readily understood.
The constructions, Figs. 13 et seq., illustrate a multiple machine for winding
sewing machine cops in which each cop shaft 1 is provided with a spindle a,
Fig. 17, and the thread guide hole or notch is in an arm 2, Figs. 14, 16, which is
pivotted to a carrier 3, Fig. 14, the latter being a hub and arm upon a rock
shaft 15 which derives its motion from another rock shaft 4 having an arm 7 into
the fork or slot a of which extends a pin 5 from the rocking carrier 3. The rock
shaft 4 is driven from a cam wheel 13, Fig. 13, into the cam groove of which
extends a stud 12 and from the latter extends a stud 9 into a slot in an arm 8
which latter is secured to the shaft 4. A slotted arm 10 carries the studs. The
cam thus imparts a reciprocating motion to the arm 8 and a rocking motion to
the shaft 4, and the arm 7 on the latter imparts a rocking motion to the carrier 3
which carries the arm 2 having the thread guide at the upper end.
The thread guide arm 2, Fig. 14, is pivotted to the carrier 3, so as to swing to
and from the cop shaft 1, whereby as the size of the cop increases, the arm 2 is
thrown back and this movement of the arm is the means of adjusting the pin 5 in
the slot a so as to gradually reduce the lateral motion imparted to the guide from
the shaft 4 thereby building up a cop gradually contracting in width from the hub
toward the outer edge.
Thus, the stud 5 may be carried by a block 6 mounted to slide in a slot in the
carrier 3, and pressed upward by a plate spring 16, and the block 6 has a forward
inclined edge y against which bears a transverse edge or shoulder 2 of the guide

page_text: arm 2, Fig. 14. When therefore, the said guide arm is thrown back in the direction
of its arrow, the shoulder z, bearing on the inclined edge y, causes the block 6 to
be thrown downward to a greater or less extent carrying with it the stud 5, thereby
reducing the distance between the stud and the axis of the shaft 4 and consequently
reducing the throw imparted to the carrier 3 by the movement of the arm 7 on said
shaft.
The carrier 3, Fig. 16, and the thread guide arm 2 are slotted for the passage
of the shaft 4, as shown.
The expansion holder a for the cop tube X may be made in different ways. It is
preferred however to make it in the form of a longitudinally split sleeve u, Fig. 16,
upon a tapering end of the shaft 1 and with a circular head 19 having an annular
groove band into the said groove 6 enters a lug 20 on a lever 21 which may be
swung outward to carry the split sleeve forward and permit the members thereof to
contract and receive the cop tube and then may be carried back to the position
shown in Fig. 5 expanding the sleeve in the cop tube and holding the latter firmly
in place.
The increment of movement described in connection with Figs. 1 to 13 is secured
by connecting together the cam 13, which drives the thread guide and the shaft 1
which drives or carries the holder for the cop by means of gears constructed as
before described. Thus the gear wheel 50, Fig. 15, upon the shaft 1, is geared
through an intermediate gear wheel 24, with a gear wheel 25, carried by but
turning upon the shaft 29 to which is secured the cam 13. The shaft 29 carries a
yoke 22, in which turns a shaft 24 carrying a pinion 30 that meshes with the teeth
of a gear 27 upon an annular flange 26 of the gear wheel 25. A friction wheel 31
upon the shaft 24 is in frictional contact at its periphery with a stationary plate 32,
all as described in connection with Figs. 1 and 5.
It will be understood that it is exceedingly desirable in winding small cops or
bobbins for sewing machines, to avoid the use of a multiplicity of winding apparatus
while at the same time it is necessary to impart the requisite movements and
variations of movements before described to each spindle carrying a cop tube and
its co-acting thread guide.
In order to secure this desirable result, there is combined with a series of cop
winding shafts 1, and with a series of thread guides, a single regulating device of the
character described or of any other suitable character that will impart the requisite
variations of movement.
One means of effecting this is illustrated in Fig. 13, where it will be seen that the
shafts 4 and 15 are prolonged so that the shaft 4 carries a series of arms 7 and the
shaft 15 a series of thread guide-carriers 3 and that there is also a series of
shafts 1.
The series of shafts 1 are connected so as to rotate together by means of inter-
mediate gears as shown and indicated while the single cam 13 drives both of the
shafts 15 and 4 and imparts the requisite movement to the various thread guides in
their proper relation to the rotation of the cop shafts.
Each thread, Fig. 14, is carried around a friction brake wheel 33, having a
peripheral groove to receive the thread, and against the shaft or hub on the
shaft 45, of said friction wheel, bears a brake 35 at the end of a lever 34.
A movable weight shown in the form of a heavy roller 37 rests upon the lever 34
and is caused to travel nearer the fulcrum of the latter in proportion as the size of
the cop increases to gradually reduce the tension. Thus a pin 44 on a lever 42
pivotted at the lower end bears against the guide arm 2 so as to be swung back as
the said guide arm is swung back and a pin 41 upon the lever 42 bears against the
edge of a pivotted lever 39 forked at the upper end and having a slot in each fork
to receive the shaft 47 of the weight 37. As the guide arm 2 swings back it carries
with it the levers 42 and 39 and the weight 37 so that as the size of the cop increases
and bears back the guide arm 2, the weight 37 is carried nearer to the fulcrum of
the lever 34 and the effect of the friction brake 35 decreases relieving the thread of
tension.

page_text: It is desirable to automatically arrest the movement of each spindle the instant
that a cop is filled. And for this purpose, shaft 1, Figs. 16 to 21 instead of being
rigidly connected with its gear 50, is connected through the medium of a clutch
consisting as shown of a tapering hub 51, which is upon the gear 50 and with the
latter turns loosely upon the shaft 1, and a movable clutch piece 52, splined to the
shaft having a socket to receive the hub 51, and tapering to correspond therewith
and with an annular shoulder v, the piece 52 being pressed towards the hub 51 by a
spring 54, and when the two parts are in contact, the shaft 1 turns with the
gear 50; but when the part 52 is thrown out, the shaft will remain stationary while
the gear 50 turns. A lever B having a handle d and a cam arm 55 may be thrown
in one direction to the left, Fig. 16, to bring said arm against the shoulder v and
throw the piece 52 to the left, a spring 56 tending to throw the arm 55 in this
direction. The arm 55 has a shoulder or lug 57, Figs. 18-21 which engages with
a suitable detent as a spring 58, and over the latter extends an eccentric or cam 59,
upon a shaft carrying an arm 60, Fig. 16, and dotted lines Figs. 18, 19, that
terminates in the stop t.
The stop t is in such position that when the thread guide arm 2 is carried back
to a sufficient extent by the completion of the bobbin, a contact piece s Fig. 16,
upon the said arm will strike the top t, rock the arm 60 and its cam 59 in the
direction of the arrow Fig. 19 and bring the said cam to bear upon and depress
the spring 58 to carry it from the shoulder 57 when the spring 56 will force down
the arm 55 of the lever B and thereby force back the piece 52 of the coupling and
uncouple the shaft 1 from the gear 50.
In order to reset the parts use is made of the cam w², Figs. 19 and 20, on the
end of the lever d, which passes through a slot wel in the arm 55, the cam w²
making contact with the spring or detent 58, when the handle is swung to one side
depressing the spring and the handle then takes a bearing on the arm 55 and swings
the latter.
The pins 9, 12, are upon a slide adjustable on the arm 10 so as to vary the extent
of movement imparted by the cam 13 by carrying the slide nearer to or further
from the axis of the arm 10.
The before described apparatus may be modified without departing from the
spirit of this invention.
