Improvements in Apparatus for Winding Yarns and Threads.
I JOSEPH ROBERT LEESON of No. 226 Devonshire Street, Boston, Massa-
chusetts, 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:-
This invention relates to apparatus for winding cops, and more especially that
class of cops in which each coil of thread is spiral and is bent back at each end of
the cop so as to form a cop with substantially flat ends.
It is considered advantageous for many purposes, and especially for those in
which use is made of cotton yarns, to employ cops of yarn of a conical shape. It
is more difficult and expensive to wind such cops in the ordinary manner because
of their unequal size at the opposite ends, and the necessity in some cases of having
solid conical blocks for winding the thread upon; and the ordinary modes of
winding such cops are apt to result in laying the thread irregularly so that the cop
is not of a uniform character throughout.
The object of the first part of my invention is to wind such cops with the same
facility as the ordinary cylindrical cops, to adapt my improved means of winding to
existing machines without material alteration thereof, or preventing their use for
winding cylinder-cops, and to enable me in winding tapering or conical cops to
make use of the mode of winding set forth in the Specification of British Letters
Patent No. 6497 for the year 1892. To this end, I make use of the means of
winding set forth hereinafter and illustrated in the accompanying drawings, in
which ;-
Fig. 1, is a plan view illustrating one form of winding mechanism embodying my
invention.
Figs. 2 and 3 are detached part sectional views of sufficient of other forms of
mechanism to illustrate my invention.
Fig. 4 is a side view of a winding machine embodying some of the features set
forth in Figs. 2 and 3, being however a "preferred construction."
Fig. 5 is an end view of the machine shown in Fig. 4.
Fig. 6 is an enlarged section on the line 5-5, Fig. 4.
In the arrangement illustrated in Fig. 1, A is the winding shaft, which, as shown,
is adapted to receive a conical holder B, which may be removed when the machine
is to be used for winding cylindrical cops; C is a reciprocating carriage, driven by
a cam X, which carriage supports a block a, to which is connected a thread
guide D, having its eye so arranged as to be opposite that point of the guide which
is maintained in contact with the cop by means of a spring b which tends to carry
the guide against the face of the cop, while permitting it to move outward as the
cop increases in size. The spindle or shaft A, is driven from the shaft E through
the medium of grooved wheels F G, and a belt c, the wheel G, being an expansion
wheel so as to secure a variation in the relative movements of the holder and guide,
and so as to vary the extent of this variation.
Instead, however, of the shaft A being parallel to the path of the reciprocating
guide D, as in other machines, it is arranged at such an angle thereto as to bring
one side of the holder B parallel to the path of the guide. By arranging the
holder B, so that at one side it is always parallel to the path of the reciprocating
guide, the thread may be wound upon a conical or other bobbin placed upon the

page_text: holder in the same manner as it could be wound upon a cylindrical tube or bobbin,
while a positive motion is imparted to the holder and bobbin, so that it is possible
to wind with much greater rapidity than when the bobbin is not positively rotated
and driven froni a shaft, while the thread is laid with much greater regularity and
uniformity, and the bobbin is more compact, regular, more sightly in appearance,
and less likely to be broken down in handling. It will also be seen that by the
arrangement described I am enabled to so actuate the shaft in respect to the guide
as to secure the peculiar arrangement and lay of the thread or yarn as specified in
the Specification of the before-mentioned British Letters Patent.
The arrangement illustrated in Fig. 1 would necessitate a special construction of
machine, and as it is desirable in many instances to adapt my improvement to
machines already in use, 1 have provided means whereby in such machines the
conical holder may be arranged with one side parallel to the path of the guide, and
yet be positively driven from the ordinary winding shaft, which is also parallel to
the path of the guide in existing machines.
In such case I provide a hollow conical holder B', Figs. 2 to 6, which I arrange
upon a conical support K, which is bolted or otherwise secured to the frame Hof
the machine, the winding end or spindle t of the shaft A' extending through an
opening in the support K, which is parallel to one side of the support, the latter
being arranged so that the said side is also parallel to the path of the guide. The
holder B is placed upon the support K, and is provided at the larger end with an
annular rack, for engaging the pinion y upon a spindle h, turning in a bearing of
the frame H, and having a pinion i, engaging a toothed pinion J upon the shaft A'.
As the shaft A' revolves, it turns the holder B', through the intermediate gears,
thereby rotating it positively in relation to the reciprocating guide B, and obtaining
the same result as shown in Fig. 1, except that the support K and conical holder
may be removed whenever it is desired to wind a cylindrical cop. In Fig. 3, a
gear-wheel connected detachably to the spindle t by a set screw, engages a gear
at the end of the holder, which is prevented from turning by a pin m.
In the construction shown in Figs. 4 and 5, there are the frame H', cam X,
shaft A', expansion wheel or pulley G, pulley F, belt C, swinging frame L,
supporting a reciprocating bracket M, to which the guide D is secured, and with a
stud s, extending into the slot of the cam X.
In the enlarged view, Fig. 6, the support K, is recessed to receive the end or
spindle of the shaft A', and also to receive the pin m, which extends into a
socket n, in the frame H, so that when the support is placed upon the spindle A',
and the pin m is put in place, it prevents any turning of the support. The
holder B is fitted to and will turn upon the support as in the construction shown
in Figs. 2 and 3, and where it is necessary to reduce friction, anti-friction balls u
may be properly inserted between the support and holler to which the conical tube
or bobbin may be applied, and held in place by a nut p, screwing on to the small
threaded end of the holder.
The holder is driven from the shaft A', through the medium of an annular bevel
gear, fitted in and secured to the holder near the small end and meshing with
teeth or an annular rack s, at the end of the spindle t, the parts being held in place
by a bolt, passing freely through an enlarged opening in the gear, and into the
end of the spindle. As the shaft rotates, it drives the gear, and with it the
holder B and the cop tube u', upon which the thread is wound.
As in the construction shown in Fig. 2, the support K is so
adjusted on the
shaft A', that one side is parallel to the path of the guide, so that while the
conical holder is rotated positively to wind the thread thereon, and while its axis is
at an angle to the path of the guide, it turus in fixel bearings, an I the guide in
traversing the face of the cop acts the same as in winding a cylindrical cop.
It will also be evident that where cops are to be wound of different tapers, each
machine may be provided with supports K, corresponding to the different sizes of
coues and adapted to be changed one for the other, or to be entirely removed when
a machine is to be used for winding cylindrical cops.

page_text: The object of the second part of this invention shown in Figs. 1 to 5ª is to
provide a simple, cheap and effective machine for winding cops, which shall be
light of structure and capable of operating at a high speed, and at the same time
be capable of accomplishing the winding of the cops in a satisfactory manner, and
to these ends this part of my invention consists in the various features of
construction and arrangement of parts for accomplishing the various purposes
substantially as hereinafter more particularly set forth.
The support for all of the parts consists of a simple flat oblong frame A, adapted
to be bolted to a standard and having bosses at the points where the shafts pass
through the same. The main driving sha't 6, at the top of the frame has a fast
pulley 7, a loose pulley 8, and a pulley 9 with a V-section groove to receive a
V-section beit 10, the ends of the shaft 6 being constructed to receive the ends of
tubes or blocks .r, upon which the thread is wound to constitute the hobbins X.
The thread is laid upon each tube by means of a reciprocating guide B, the two
guides being carried by a rod 12, which slides back and forth in bearings in the
frame under the action of a cam C, upon a shaft 13, which is provided with a
gear 14, driven from a pinion 15, upon a shaft 16, the latter carrying an expansion
pulley E, around which passes the belt 10,
It has been found very desirable in this class of winding machines to reduce the
weight of the parts connected to the reciprocating guides, because if the parts are
heavy, the momentum is very great when the guides are driven at a high rate of
speed and there is a tendency to misplace the thread, which to effect the winding
of a cross wind must be laid with the greatest regularity. My effort therefore has
been to reduce the weight of these parts while maintaining the guides in constant
contact with the cop permitting them to swing back as the cop increases in size and
reciprocating them with the desired speed. I reduce the weight of the cam,
forming it so as to constitute practically an open flanged ring 20, mounted by
spokes 21, extending from a hub 22 angularly upon the shaft 13. This secures all
the effective portions of the eam, dispensing with superfluous weight. I prefer to
split the hub 22, at one side and pass a clamping screw 23 through the slit portion
so as to tightly secure the cam to the shaft 13, without the use of any key and the
necessity of slotting the shaft.
In order to maintain the belt 10 taut, I mount the shaft 16 in a frame F,
pivotted to the shaft 13, so as to swing freely, thereby bringing the weight of the
frame, shaft 16 and pulley E to bear upon the belt 10 to keep it under constant
tension, and as the frame F swings upon an axis concentric with the axis of the
gear 14, the pinion 15 is maintained in proper relation to the gear 14, regardless of
the position of the frame F.
In order to aid in maintaining the belt 10 tight and to prevent any rebound of
the frame F, I find it advantageous to use in some cases a weight W, hung by a
cord W to the frame F, and the cord may be passed round a pin W2 on the
frame A to steady the frame F and prevent too rapid action.
Each guide B consists of a divided arm 25, extending from a split hub 26 which
carries the two cruss-pieces 27, 28, a flat plate 29, having a V-shaped notch 4, and
a beut rod 30, having a guide eye 31, at the end, screws or bolts 33, passing
through the plate 29 and rod 30, into the arm 25 and securing the plate and rod
detachably to the arm, thereby permitting the character of the notch and the
position of the guide eye to be altered for different characters of thread. To the
rod 12, between the branches of each split arm 25, is secured a split ring 35, which
may be clamped tightly to the rod by a screw 36, passing through ears 37 of said
ring. A spring 38 connected at one end with a cross-bar 27, is attached at the
other end to a stud 39, on the ring 35, and tends to carry the upper end of the guide
towards the cop while permitting it to swing back readily, the cross-piece 28, by
its contact with the long ear 37, limiting the swinging movement of the guide
towards the cop. This construction of the guide secures all of the necessary
features and actions while greatly reducing the weight of the parts heretofore
employed to secure both the reciprocating aud swinging actions.

page_text: The rod 12 is driven from the cam C, through the medium of a cross arm 40,
clamped to the rod and forked at one end to embrace a spool 41, sliding on a
rod 42, and the cross-arm carries a pin with an anti-friction roller 43, which extends
into the slot of the cam.
To facilitate the support and insertion and removal of the tubular holders or
bobbins I attach to the rod 42 blocks 46, each carrying a swinging arm 47, having
a freely revolving atud 48, for receiving one end of the bobbin X, the opposite
end of which fits the end of the shaft 6, a spring 49, throwing the arm 47 inward
so as to cause its stud to bear firmly against the end of the bobbin. The block 46
is provided with an arm 50, into which screws a set screw 51, so as to regulate the
extent of the inward movement of the swinging arm 47.
In devices of this character it is desirable to automatically throw the apparatus
out of operation as soon as a bobbin reaches the proper size. For this purpose
I make use of a belt shifter G consisting of a yoke 55, upon a sliding shaft 56,
through which yoke passes the driving belt H. A spring 57 tends to throw the
shaft and yoke to a position to shift the belt on to the loose pulley and stop
the machine. The frame of the machine is provided with a recess M, (Fig. 5A)
which is adapted to be engaged by a projection e, on the belt shifter G, and the
spring 57 is so applied as to tend to throw the yoke inward. At each end of the
rod 56 is adjustably mounted an arm 59 through the outer end of which passes a
screw 60, having a milled head 61 at the outer end and a bearing 62 at the inner
end, see Fig. 3. When the machine is in operation the parts are as shown in
Fig. 1, with the belt H on the driving pulley 7. The parts are so adjusted that
when a cop reaches its proper size, it bears against the bearing 62, rocks the
arm 59, and shaft 56, carrying the pin ", away from the recess u, when the
spring 57 throws the yoke so as to carry the belt H on to the idler pulley 8.
The expansion pulley E is simplified by forming the fixed section 60", which
is bolted to the shaft 16, with a long hub 61, threaded at the outer end. The
sliding section has a disc 62, and a hollow collar 63, which slides on the hub 61",
and an intervening spring 64 tends to throw the section 62 outward. A nut 65
turns on the threaded end of the hub and by turning this nut in one direction the
movable section is brought towards the fixed section and by turning the nut in
the opposite direction the movable section is carried outward by the spring. Any
suitable means may be employed for locking the nut, but I prefer to make a
transverse slit we in the periphery of the nut at one side, to place a loose perforated
disc 68 in this slit and to pass a screw 69 through the slit portion of the nut
and through the disc (see Fig. 14 and 2). When the screw is loosened, the disc
will accommodate itself to the movements of the nut, but when the screw is
tightened, the dise is held in engagement with the threads of the hub in such
manner as to prevent the nut from being turned.
I do not limit this invention to the precise construction and arrangement of
