Improvements in Yarn Winding Machinery.
We JOHN DEMPSTER WHYTE, of Falcon Works, Poland Street, Manchester in the
County of Lancaster, Engineer, and WHYTE'S PATENTS, LIMITED, of Dale Street
Chambers, Kirkgate, Bradford, in the County of York, do hereby declare the nature
of this invention to be as follows:-
The
Our said invention relates to improved apparatus for winding yarn and has for its
objects to widen the scope of usefulness of such machinery and to improve the
quality of the work turned out thereby. For example under our invention we are
enabled to wind successfully upon the bare spindle and also to produce large cops for
warping and other purposes the contents of which would ordinarily be wound upon
bobbins. In apparatus made in accordance with our invention the spindles are
lowered as the winding on proceeds and in the following description we will, refer to
one spindle and its dependent parts instead of referring throughout to these in the
plural it being understood that a frame may be fitted with any convenient number of
such spindles and parts. Each spindle then is independently carried in a frame or
on supports the said frame or supports sliding on guide spindles extending between
fixed rails bolted to the end frames of the machine. To the said frame or supports
we secure a rack of sufficient length to bring about the required lowering of the
spindle. With this rack there gears a toothed pinion carried on one end of a shaft,
the other end being furnished with a frictional pulley capable of adjustment on the
shaft. The said friction pulley is in contact with a friction disc which is one of a
series of discs carried on a shaft extending throughout the length of the winding
frame and caused to revolve by any suitable driving means such for example as a
countershaft with worm and worm wheel driven from the tin roller shaft.
friction disc is secured to its shaft by a slip feather and groove or other suitable
arrangement which will permit the disc to slide on the shaft while revolving therewith.
The boss of the disc has a groove with which engages a pin on a horizontal lever
pivotted to one of the fixed rails or parts of the machine, and which will be hereafter
referred to. The weight of the frame or supports carrying the spindle and the spindle
and parts is counterbalanced by a weight, the cord or chain of which passes over a
grooved brake pulley also centred on a fixed rai!. When the machine is in operation
the toothed pinion engaging with the rack is slowly and continuously revolved from
the friction disc so as to lower the spindle gradually as the winding on of the cop
proceeds. The spindle is driven by a band from the tin roller or its equivalent the
band passing beneath a guide pulley secured on the fixed rail and also partly around
a pulley carried on the upper end of a lever pivotted to a fixed rail or part, its lower
end operating the aforesaid lever which shifts the friction dise and also governing a
brake lever adapted to engage with and brake the grooved brake pulley over which
the counterbalance weight cord passes. Upon this pivotted lever a drop finger is
loosely centred the outer end of the finger having an eye through which the yarn
passes on its way to the cop. Beneath this finger is a revolving or reciprocating cam
or finger shaft a recess or notch in the lower side of the finger being kept out of reach

page_text: of the said cam by the yarn. But should the yarn accidentally break the finger falls
and the cam catching the finger pushes it forward drawing forward the carrier pulley
lever and slackening the driving band. As it is essential for the prevention of
inequalities in the cop that the downward traverse of the spindle should at the same
time be arrested, the lower end of the carrier pulley lever first of all releases the
pivotted brake lever which drops down and brakes the counterbalance weight pulley
so as to arrest the traverse of the spindle, while at the same time but following the
release of the brake lever the continued movement of the lever shifts the lever which
moves the friction disc away from the friction pulley, thus stopping the rotation of
the rack pinion. The shape of a slot in the horizontal lever with which the said
lower end of the carrier pulley lever engages, permits of these successive and
continuous movements. The parts are returned by the attendant to their normal
position when piecing up has been effected.
To effect the building of a cop, say for example a large warp cop (or it might be
a smaller or weft cop) with a flattened or only slightly rounded bottom, we provide
means whereby the movement of the yarn guide passes from a minimum to a
maximum traverse, when the cop is being commenced and this is brought about by
the following arrangements of mechanism. For instance in one arrangement
specially suitable for the winding of large warp cops we arrange a tapering or cone
shaped eam driven preferably by a bight of the driving band from the tin roller.
Upon this cam there rests the lower end of a sliding jack which carries the wire guide
which traverses and lays the yarn on the cop. This jack slides in a stock loosely
pivotted on a fixel rail or part. The smaller end of the cone shaped cam represents
the minimum traverse of the yarn guide the larger end represents the maximum
When the cop is being started the pivotted stock and jack are about
perpendicular, the frictional bowl on the foot of the jack resting on the smaller end of
the cam. When the winding starts the jack moves only slightly the spindle at the
same time beginning to be lowered. The top support of the spindle carries a plate
with an inclined slot which receives a pin projecting from the pivotted stock.
slotted plate drops, the slot begins to move the pin and consequently the lower end
of the stock to one side, that is towards the larger end of the conical cam, and the
longer this side movement of the jack and stock is continued the larger becomes the
traverse of the yarn guide, which means that the guide is dropped a little more every
traverse and this co-operates with the retreat of the spindle to produce a flattened
bottom to the cop. When the stock has been so far noved that the jack rests on the
larger end of the cam, the pin leaves the slot and at the same time to keep the stock
locked in its inclined position a jawed clip falls over automatically and secures the
stock in its inclined position. We might however extend the plate with a straight
slot to confine the pin, instead of the said locking clip. The building now continues
with the maximum traverse to the end of the cop. An advantage derived from the
throwing of the stock into an angular position as the winding proceeds is that the
yarn guide is traversed at the same angle as the nose of the cop the guide lying close
to the cop as the building proceeds. The cam is preferably made with a quick drop
ridge in its circumference so as to move the yarn guide rapidly away from the nose
of the cop and so prevent an overwound on soft peak to the nose. To equilise the
delivery of the yarn to the guide and prevent slack we place an inverted cone in front
of the cop nose the cone having its smaller end opposite to the base of the cop nose
and its larger end opposite to the nose tip. We night however use a fixed angled
plate or wire as a substitute for the said cone. We do not confine ourselves to the
conical cam as described to obtain the traverse. We might for instance in place of
the conical cam and especially when it is proposed to wind the smaller weft cops use
a cam disc or a crank arranged to operate a lever carrying the yarn guide the pivot
or fulcrum of the said lever being either fixed or adjustable so as to be capable of
varying the traverse. With the same object we might use a dise eccentrically carried
on a shaft so as to wobble or oscillate in revolving, a projection or bowl from the
yarn guide lever resting on the face of the said dise. This projection or bowl might
be made automatically movable so as to give the varying traverse when the cop is

page_text: started, and the face of the disc might be fashioned so as to give the required quick
reversal at the peak of the cop nose. The arc through which the yarn guide is
vibrated by the lever operated by these latter devices is arranged to be approximately
close to the slope of the cop nose, so as to keep the guide close to the cop.
Our improved method of winding, confers advantages both in warping and
weaving with cops so wound. For instance in warping frames the absence of the
usual bobbins economises space and the yarn being drawn either from the interior or
exterior of the cops, the latter may be placed on closely pitched tongues or into
holders mounted on the warping mill, the noses or ends of the cops being towards the
warping mill reeds.
Improvements in Yarn Winding Machinery.
We JOHN DEMPSTER WHYTE, of 31 Lime Avenue, Urinston, near Marchester, in
the County of Lancaster, Engineer, also of Falcon Works, Poland Street, Manchester,
aforesaid, and WHYTES PATENTS, LIMITED, of 94 King Street, Manchester, aforesaid,
late of Dale Street Chambers, Kirkgate, Bradford, Yorks, 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 and
accompanying drawings:-
Our said invention relates to improved apparatus for winding yarn and has for it
object to widen the scope of usefulness of such machinery and to improve the quality
of the work turned out thereby. For example under our invention we are enabled to
wind successfully upon the bare spindle without the use of the usual guide cups or
substitutes therefor and also to produce large cops for warping and other purposes
the contents of which would ordinarily be wound upon bobbins.
According to our invention we carry the spindle vertically in a suitable carriage and
lower the same as the winding on of the yarn proceeds. The lowering of the spindle
is effected by means of a friction pulley operating suitable gearing and driven by a
disc. We employ a cone shaped cam to operate the yarn guide, the formation of the
cam and the method of operating the yarn guide therewith enabling us to vary the
length of traverse of the yarn guide. By varying the traverse of the yarn guide from
its minimum to a maximum traverse at the commencement of the build of a cop we
are enabled to produce cops with a flattened or slightly rounded bottom. This is
particularly useful in the production of large cops for warping or other purposes.
The improvements will be best understood by a detailed description of the annexed
four sheets of drawings.
Fig. 1 is a side elevation of a spindle carrying a warp cop in the net of being wound
the adjacent parts which effect and regulate the winding being shown in conjunction
5 with the said spindle,

page_text: Figs. 14 to 23 are detailed views of the apparatus.
Figs. 24 to 27 show further modified methods of operating the yarn guide.
It will be understood that although in the following description we will refer to
one spindle and its accompanying parts nevertheless it must be understood that a
frame may be fitted with any convenient number of such spindles and parts.
Referring in the first place to Sheets 1 and 2 we lower the spindles as the winding on
proceeds and to admit of this each spindle a is independently carried in bearings in
supports 6 61 the said supports being braced together by a rack bar e extending
between the supports. The supports bb' are formed in plan as most plainly shown
in Fig. 5, and slide on rods d d extending between fixed rails e* c* bolted to the end
frame of the machine. With the aforesaid rack bar c there gears a toothed pinion e
carried on one end of a shaft e¹ the said shaft being supported in bearings e²e from
the bracket e bolted to the fixed rail or beam f. The inner end of the shaft e¹ is
furnished with a friction pulley e as shown in dotted lines capable of adjustment on
the shaft e¹ so as to be set nearer to or further from the centre of the disc g. The
method of adjusting the pinion et on the shaft e¹ is more clearly described and shown
with reference to Fig. 14 of the drawings.
The periphery of the friction pulley is preferably covered with rubber and the
pulley rests in frictional contact with the disc g which is one of a series of similar
dises carried on a shaft g¹ extending throughout the length of the winding frame.
The said shaft g' is caused to revolve slowly by worm gearing driven from the driving
shaft h, the said slow motion gear not being shown on the drawings and being of any
convenient or suitable nature. The disc g is secured to its shaft g' by a slip feather
and groove or other suitable arrangement which will permit the disc to slide on the
shaft while revolving therewith. The boss of the disc g has a groove g³ with which
engages a pin on a horizontal lever i pivotted at upon the fixed beam f.
This lever and its functions will be hereinafter referred to. The weight of the
supports b b and the spindle and other objects carried thereby is counterbalanced by
a weight j in the following manner. A cord or chain j¹ is secured at one end to a
bracket bolted to the carriage b.
The chain passes over a grooved brake pulley k carried on a stud projecting from
the fixed beam f the other end of the chain being attached to the weight j.
When the machine is in operation the toothed pinion e engaging with the rack cis
slowly and continuously revolved by the frictional driving effects of the disc g on the
friction pulley e in such a direction as to lower the spindle gradually as the winding
of the cop proceeds.
The spindle a is driven by a band from the grooved pulley h¹ or its equivalent
mounted on the shaft h the band passing partly around the barrel a¹ of the spindle,
thence beneath a guide pulley et carried by the bracket e thence over a pulley mi
carried on the upper end of a lever m pivotted at me upon a projection from the

page_text: fixed rail, thence to the pulley n' which drives the spindle of the building cam n
and so back to the grooved pulley A'.
""
The lower end of the pivotted lever m acts so as at times to shift the disc g on its
shaft clear of the friction pulley e and also so as to operate a brake lever o pivotted
at o¹ to the bracket. The head o² of the brake lever is formed of a crescent shape
to fit over a portion of the periphery of the pulley over which the counterbalance
weight cord passes. The lever m also carries loosely pivotted thereto a drop lever or
finger p having an eye at its outer end through which the yarn q passes on its way
to the cop. The finger p is thus upheld clear of a reciprocating cam which lies.
opposite to a notch or recess in the finger p. The method of operating the
reciprocating cam is clearly described with reference to Fig. 18. Should the yarn
accidentally break, the finger p drops and the cam catching in the notch pushes the
finger forward and thus pulls forward the pivotted lever m against the resistance of a
spring m³ which connects the upper end of the lever to a fixed bar m, the throwing
forward of the lever m and the pulley slackens the band which thus ceases to
drive. At the same time the lower end of the lever m releases the heel of the brake
lever o which falls partly by its own weight and partly by the pull of a spring of which
brings the crescent braking hend o down upon the pulley and holds it firmly.
This prevents the spindle and cop from dropping or moving after the breakage of the
yarn, and it is very essential that this should be done, otherwise inequalities would
arise in the cop. It will be noted from an inspection of Fig. 2 that the operated end
of the lever i is formed with a slot 3 the said slot being straight at first and then
inclined. This is for the following reason. It will be clear that before relieving the
friction pulley et from contact with the disc g it is necessary to apply the brake
lever o therefore during the movement of the lever m which releases the brake o the
tail of the lever m is passing along the straight portion of the slot and
therefore does not move the lever i.
But as soon as the brake has descended on and gripped the pulley & thus preventing
all perpendicular movement of the spindle, the tail of the lever m enters and moves
along the inclined portion of the slot & thereby turning the lever i on its pivot and
moving the disc g along the shaft g sufficiently to disengage it from the friction
pulley e. The parts are returned by the attendant to their normal position when
piccing up has been effected.
To effect the building of a cop say for example a large warp cop such as the
cop g shown in Fig. 1 with a flattened or only slightly rounded bottom, we provide
means whereby the movement of the yarn guide s commences when the cop is
starting to be built, with a minimum traverse and gradually increases while the
bottom is being formed to a maximum traverse with which traverse the main body
of the cop is built and finished. This is brought about by the arrangements of
mechanism hereinafter described. For the purpose of our invention we employ a
cone shaped cam n which is best seen in Fig. 6 of the drawings, this cam being
mounted on the spindle which carries the band pulley n', the cam being thus
revolved.
The smaller end of the cone shaped cam represents the minimum traverse or
throw of the yarn guide s. The larger end represents the maximum traverse. Upon
the cam there rests the lower end of a sliding jack t the said jack & carrying the yarn
guide s. This guide s has an eye 8' opposite to the spindle a and when the cone u is
used the purpose of which is hereafter described is prolonged to present another
eye in proximity to the cone u. This cone u might be dispensed with and its
purpose when used is to regulate the taking up of slack yarn from the bank. The
cone u is carried in a loose pivot bearing at the foot of the cone as shown in
Fig. 1, the cone being of the same slope as the angle of the top of the cop but
inverted relatively thereto, the small end of the cone being opposite to the base of
the cop nose while the larger end of the cone is opposite to the peak of
the cop nose. It will be evident that as the speed of revolution of the spindle is
constant that more yarn will be taken from the hank as it is being wound upon the
base of the cop nose than when it is being wound upon the apex.

page_text: Therefore as the yarn guide & approaches the apex of the cop nose the yarn sags
and an unequal tension or pull upon the bank is thus exerted, the yarn being pulled
in a jerky manner. By passing the yarn around the cone u this objection is overcome,
the inverted cone u taking up the slack of the yarn as it is directed by the yarn
guide to the apex of the cop nose and thus acting as a compensating medium. Thus
a steady pull upon the yarn is exerted throughout the winding. The aforesaid
sliding jack t slides in bearings on the stock v the said stock being loosely
pivotted at upon a bracket w bolted to the fixed rail e. When the cop is being
commenced the pivotted stock and jack a, t are about perpendicular as indicated for
example in dotted lines in Fig. 6 a friction bowl at the foot of the jack resting on the
smaller end of the conical cam n. When the winding on commences the smaller end
of the conical cam reciprocates the jack t only slightly, the spindle a at the same
time beginning to be lowered by the action of the toothed pinion e on the rack c.
The top support of the spindle carries a plate x with an inclined slot as plainly
shown in Fig. 7 the inclined slot being occupied at the commencement of the
building of the cop by a pin a projecting from the back of the pivotted stock.
the slotted plate descends with the lowered spindle support bt the influence of the
slot acting on the pin moves the lower end of the pivotted stock to one side that is
towards the larger end of the conical cam n.
As
The longer this side movement of the jack or stock is continued the larger becomes
the traverse of the yarn guide s, which, co-operating with the simultaneous lowering
of the spindle produces the required flattened or slightly rounded bottom of the cop.
When the stock has been so far moved that the jack t rests on the larger end of
the can n as is shown in full lines in Fig. 6 the plate ieaves the pin on the
stock and at the same time to keep the stock in its angular position a jawed
locking clip y falls over by its own weight and secures the stock in its inclined
position, the building of the cop then proceeding under the maximum traverse until
completion., An advantage derived from the throwing of the stock v into the angular
position is that as the winding proceeds the yarn guide a is traversed at the same
angle as the nose of the cop, the guide thus lying close to the cop as the building
proceeds. In order to maintain the sliding jack in contact with the cam n a coiled
spring is secured at one end to the jack t and the other to the stock vas.shown in
Fig. 1. The cam is preferably made with a quick drop ridge or step in its
circumference as plainly shown in Fig. 1 so as to move the yarn guide & quickly away
from the nose of the cop at the moment of reversal and so prevent an overwound or
soft peak to the nose.
On Sheet 3 we show a modified form of apparatus which we have found highly
successful in practice.
It will be noted from the following description and an inspection of the drawings
that the essential features of our invention are preserved in their entirety, the
differences being in detail only. The spindle as before is lowered as the winding on
proceeds, such lowering being effected by means of a friction pulley operated by a
frictional driving disc, whilst the cone shaped cam is again utilized to operate the
yara guide.
The spindle 10 is secured to the revolving sheath 11 which sheath is adapted to
revolve in hearings formed in the sliding supports 12. The supports 12 are adapted
to slide on rods 13. A frictional pulley 14 driven from the disc 15 mounted on the
shaft 16 which receives a slow motion by any suitable reducing gear operates
the descent of the spindle as the winding proceeds in the following manner. Upon the
shaft 17 on which the pulley 14 is mounted is a grooved pulley 18 to which is secured
a cord 19 carrying a weight 20. Upon the end of the shaft 17 is mounted a plain
pulley 21 to which is secured one end of a cord 22 the other end of the cord being
attached to the upper support 12 of the spindle carriage. To the lower support 12
of the spindle carriage is securèd another cord 23 passing over a pulley 24 mounted
in bearings in the bracket 25. The cord 23 carries a counterbalance weight 26.
When the spindle chrringe is in its highest position as indicated in the drawings, the
cord 19 is wound to some extent upon the pulley 18.

page_text: By the revolution of the shaft 17 the cord 19 is unwound from the pulley 18, the
cord 22 being wound upon the plain pulley 21 thus pulling down the spindle carriage
as the winding of the cop proceeds. The pull of the weight 20 is counterbalanced by
the counterbalance weight 26 which exerts a pull upon the spindle carriage in a
direction contrary to that exerted by the weight 20.
The spindle carriage is thus counterbalanced or held in equilibrium and its down-
ward traverse arrested immediately the friction pulley 14 is moved out of contact with
the driving disc 15. The method of adjusting the friction pulley 14 upon the shaft 17
to vary the speed of downward traverse of the spindle carriage is clearly shown in the
plan view Fig. 14. The pulley 14 is slidably mounted upon the revolving shaft 17 by
means of a slip feather and groove or the like so that whilst revolving with the
shaft 17 it is capable of being slid along the same. A fork 27 engages with the boss
of the pulley 14 the other end of the fork being formed as a nut engaging with a
screw 28. By operating the screw 28 by means of the projecting nut 29 the pulley 14
may be traversed along the shaft 17.
The spindle 10 is driven by means of an endless cord 29 passing partly around a
grooved pulley 30 mounted on the spindle of the conical building cam 31, and from
thence under two pullies 32 mounted to revolve in bearings in the bracket 25 to a
sliding wharve 33 upon the spindle sheath 11. The wharve is slidably mounted on
the spindle sheath 11 by means of a slip feather and groove so that while the sheath
is driven it is enabled to slide within the boss of the wharve 33.
Instead of moving the driving disc 15 away from the friction pulley 14 on the
breakage of the yarn as in the apparatus illustrated on Sheets 1 and 2 of the drawings
we move the pulley 14 from contact with the driving disc.
This is effected in the following manner. Upon the driving shaft 34 we mount a
band pulley 35 whereby motion is communicated by means of a band or belt 36 to the
pulley 30 mounted on the spindle of the conical cam 31.
The pulley 30 is formed double to accommodate the driving belt 36 and the cord 29
as plainly shown in edge view in Fig. 22. A pendent lever 37 pivotted on the axis of
the conical cam 31 carries adjustably secured to it a pulley 38. When in the position
shown in Fig. 12 and in full lines in the detail view Fig. 21 the pulley 38 maintains
the belt 36 faut so as to drive the pulley 30 and with it the conical cam 31. A double
lever 39 loosely pivotted to the bracket 40 is connected by a link 41 to a lever 42.
The upper end of the lever 42 carries an antifriction bowl 43 upon which rests the
pendent lever 37. The lower end of the lever 42 is loosely pivotted upon a stud 44
secured to the bracket 25 and is formed with an extension 45 carrying at its lower end
a bowl 46. A drop lever or finger 47 is mounted to turn upon a pivot 48 secured to
the lever 42. The end of the drop lever 47 projects through a slot in the plate 49
secured to the frame of the apparatus and bears against the underside of the
drop wire 50. The end of the drop lever 47 is preferably bent at a right angle at the
point where it is brought to bear beneath the drop wire 50. The drop wire 50 is
pivotted at 51 to the bent plate or guide 52 and is maintained in its raised position
shown in Fig. 12 by means of the yarn 53. On the breakage of the yarn the drop
wire 50 falls, depressing the drop lever 47 and thus bringing an abutment 47" on the
lever 47 in the path of a stud 54 carried by a finger 55 secured to an oscillating
shaft 56. The drop finger 47 is thus pulled forward drawing with it the lever 42 into
the position shown in dotted lines in the detail view Fig. 21 thus allowing the
pendent lever 37 to drop and slackening the driving band 36 which thus ceases to
drive the pulley 30 and with it the cone cam 31. The band pulley 35 is made double
and is utilized to drive a corresponding pulley 30 on the rear side of the frame. The
method of oscillating the shaft 56 is indicated in the diagrammatic view Fig. 18. Upon
the driving shaft 34 is mounted a spur wheel 57 gearing with a spur pinion 58
revolving in suitable bearings.
Connecting rods 59 mounted loosely on a stud 60 fixed on the pinion 58 are loosely
secured to cranks 59³. Consequently the continued revolution of the pinion 58.
socillates the cranks 59* which are secured to the ends of the shafts 56. The move-

page_text: ment thus imparted to these shafts is communicated to the fingers 55 mounted
on the shafts 56.
The diagrain represents the arrangement in duplicate where spindles are mounted
at each side of the winding frame.. To stop the revolution of the friction pulley 14
simultaneously with the cone cam 31 on the breakage of the yarn we mount the
bracket 61 carrying the friction pulley to rock upon a pivot 62 as shown most clearly
in the detail view Fig. 23. A spring 63 maintains the pulley 14 in frictional driving
contact with the driving disc 15 during the working of the apparatus.
We form an incline 64 upon the bracket 61 against which bears the bowl 46 carried
by the extension 45 of the lever 42.
This incline and bowl will be most clearly seen in the plan view Fig. 14.
When in the position shown in dotted lines in Fig. 21 the bowl 46 traverses the
incline 64 thus turning the bracket 61 upon its pivot 62 in the direction of the arrow
Fig. 23. The friction pulley 14 is thus withdrawn from contact with the driving
disc 15 and the downward traverse of the spindle is arrested. The driving dise may
therefore be utilized to netnate two spindle carriages one at each side of the apparatus
as indicated in Fig. 12, the pinion 14 operating the spindle carriage in the rear.
When "piecing up has been effected the attendant by pulling down the lever 42
by means of the handle returns the parts to their normal positions. The pulley 38
on the pendent lever 37 again tightens the belt 36 whilst the spring 63 returns the
pivotted bracket into its working position thus again bringing the friction pulley 14
into driving contact with the disc 15.
The yarn guide 65 is pivotted at 66 to a finger 67 secured to a spindle 68 which
can turn freely in a bracket 69 bolted to the top rail of the apparatus.
A bowl 70 upon the yarn guide 65 rests upon the cone cam 31 and is maintained
in contact with the cam by means of a spring 71 secured at one end to the yarn guide
and at the other to an extension of the finger 67 as clearly shown in Fig. 12. As in
the apparatus shown in Sheets 1 and 2 the yarn guide is arranged to be traversed
from the smaller end of the cone cam 31 to its larger end so as to vary the traverse
of the yarn guide from a minimum to a maximum traverse at the commencement of
the build of the cop. This is effected in the following manner. Upon the spindle 68
to which the finger 67 carrying the yarn guide is secured, we key a bell crank
lever 72. The upper end of the bell crank lever 72 is connected to a spring 73 the
tendency of which is to turn the spindle 68 upon its axis in the bracket 69, and thus
traverse the bowl 70 along the conical cam 31. This will be more plainly seen from
an inspection of Fig. 13. The lower end of the bell crank lever 72 is provided with
a finger or pin 74. The upper support 12 of the spindle carriage carries a copping
plate 75. This copping plate is shown separately in Fig. 17. At the commencement
of the build of the cop when the parts are in the position shown in Figs. 12 and 13
the pin 74 rests against the edge of the copping plate and is maintained in contact
therewith by the pull of the spring 73.
On the descent of the copping plate 75 the pin 74 follows the contour of the edge
of the plate and the spindle 68 is thereby gradually turned on its axis thus traversing
the bowl 70 on the yarn guide 65, from the smaller to the larger diameter of the cone
cam 31, canting the finger 67 carrying the yarn guide 65 and increasing the traverse
of the yarn guide. When the maximum traverse has been attained a snug 76 upon
the finger 67 coines in contact with a screwed stop 77 carried by the bracket 69 and
the yarn guide is maintained in this position, throughout the downward traverse of the
spindle carriage, by the pull of the spring 73. Figs. 15 and 16 show the snug 76
and screwed top 77 more clearly, Fig. 15 being a plan view of the parts with the top
rail removed whilst Fig. 16 is a plan view of the bracket 69 and the finger 67 to which
the yarn guide is pivotted. It will be evident that by operating the screwed stop 77
the traverse of the bowl 70 upon the yarn guide 65 may be regulated so as to
vary the maximum traverse of the yarn guide 65. By pivotting the yarn guide 65
to the finger 67 as illustrated in Fig. 12 the requisite length of traverse of the yarn
guide eye inay be obtained with a smaller cone cam 31 than is the case with the fixed
yarn guide illustrated in Sheets 1 and 2. Figs. 19 and 20 illustrate respectively in

page_text: side and end view the cone cam 31. The can is formed with a quick drop ridge as
shown in dotted lines so as to provide for a rapid descent of the yarn guide from the
nose of the cop at the movement of the reversal so as to prevent an overwound or soft
peak to the nose. If considered desirable however this drop ridge may be dispensed
with.
The yarn passes from the cops (not shown in the drawings) through the tension
device 78 see Fig. 12.
The tension device 78 consists of two barrels covered with felt or the like and fixed
to a bracket carried on a rod extending throughout the length of the frame.
The bracket is loosely mounted on the rod and secured thereto by a wing nut. By
altering the angle of the bracket the tension on the yarn may be varied.
When winding from the lank the tension device 78 may be dispensed with. From
the tension device 78 the yarn is led over a curved plate 52 to the eye of the drop
wire 50 and from thence through a slot 79 in the plate 52 to the eye of the yarn
guide 65. This is clearly shown in the plan view Fig. 12 of the plate 52. When
winding on the base of the cop the yarn is conducted straight from the eye of the drop
wire 50 to the cop.
But when raised to the tip of the cop nose by the yarn guide 65 it is directed
against the underside of the curved portion 80 of the plate 52 which thus serves to
put an increased tension on the yarn as it is being wound upon the thinner portion
of the cop nose.
We do not confine ourselves to the conical cam n as a means of obtaining the
building traverse of the yarn guide. We might for instance in place of the described
cam, jack and stock, illustrated in Sheets 1 and 2 and the modification thereof shown
in Sheet 3. use the inclined or wobbling disc & shown in Fig. 3 Sheet 1.
Here we employ a lever 2 pivotted at its lower end to the frame of the apparatus as
shown in Fig. 9 Sheet 2 and carrying on its free end an arm 3 to a prolongation of
which the yarn guide s is attached. A strut 4 is mounted on the arm 3 the said strut
sliding on a square rod 5 and engaging with a collar 6 carried on a screw 7 held in
the arm 3. A prolongation of the shaft which carries the cam disc is fitted with a
fixed arın 8 which sweeps over the collar 6 as the cam revolves and by advancing the
collar on the screw at the same time advances the strut from the centre towards the
outer circumference of the disu . The fixed arm 8 is made long enough to operate
the collar and strut during the building of the bottom of the cop. When the collar 6
has moved out of the range of the fixed arm the maximum traverse has been attained
and goes on till the cop is completed.
The cam disc is mounted and driven as indicated in Fig. 9. It must be under-
stood however that we do not claim the wobbling disc per se as being novel.
The are vibrated through by the outer end or eye of the yarn guide a is approximate
to the inclination of the cop nose (see for example Fig. 8). Fig. 8 shows a form of
grooved disc cam 9 which might be used to give the traverse to the yarn guide 8.
In this example which together with remaining examples of traversing mechanism
are intended to be applied more especially in the winding of the smaller weft cops,
there is no attempt to vary the traverse at the commencement of the cop, a flattened
bottom to such smaller cops not being an essential. In Fig. 9 the disc cam used is
similar to the cam shown in Fig. 3 and acts in the same manner except that there is
no attempt made to vary the traverse as in Fig. 3, the maximum traverse being
preserved from first to last. In the wobbling cam disc shown in Figs. 3 and 9 there
is a ledge or step as more plainly shown at Fig. 10 to give the desired quick reverse
at the peak of the cop nose.
In Fig. 11 we make use of a crank instead of a cam to give the required oscillation
to the yarn guide. Here also there is no attempt to vary the traverse. We wish it
to be understood however that we do not claim separately as being novel the
arrangements shown in Figs. 8, 9 and 11.
Further modified methods of obtaining the requisite traverse of the yarn guide are
indicated in Figs. 24 to 27 Sheet 4.
In Figs. 24 and 25 the pulley 30 is provided with an excentrically mounted pin 81,
B

page_text: which may carry an anti-friction sleeve, upon which the yarn guide rests and is
oscillated by the revolution of the pulley 30. Instead of the pin 81 an excentrically
mounted angle plate 82 may be employed as indicated in Figs. 26 and 27.
In the example illustrated by Figs. 24 and 25 the length of tmverse of the yarn
guide is not varied, but in Figs. 26 and 27 the yarn guide may be traversed from the
smaller to the larger end of the angle plate 82 when forming the cop bottom, so as
to gradually lengthen the traverse of the yarn guide as the cop bottom is being
formed. Thus the example indicated in Figs. 26 and 27 may be used for the winding
of the larger cops.
Our improved method of winding confers advantages in warping with cops so
'wound.
For example in warping frames the absence of the usual bulky bobbins economises
space, and the yarn being drawn either from the interior or the exterior of the cops,
the latter may be placed on closely pitched cop tongues or spindles or into holders
mounted closely together on uprights or on a frame, the noses or ends of the cops
being towards the warp mill reeds.
In winding yarn upon the bare spindle the cone shaped cam or its equivalent is
driven so as to impart a rapid vibratory movement to the yarn guide thus producing
cross wound cops. By reducing the speed of the cam a slow vibratory movement may
be given to the yarn guide if desired so that instead of cross winding, the yarn may be
wound in closely pitched superimposed spiral layers. In the latter case it would
be necessary however to wind the yarn upon paper tubes or bobbins.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that
what we claim is.
(1) In apparatus for winding yarn into cops the employment of a cone shaped cam
such as n, upon which the yarn guide is traversed from the smaller to the larger
diameter so as to obtain a variation in the throw of the yarn guide from a minimum
to a maximum as the formation of the cop bottom proceeds substantially as described
and illustrated.
(2) In apparatus for winding yarn into cops, carrying the spindle in supports or in
a frame capable of being lowered as the winding on proceeds by means of a rack and
pinion or pulley and cord operated from a friction dise and used in combination with
any of the indicated traversing motions for building the cop, substantially as described
and illustrated.
(3) The improved means for modifying the traverse of the yarn guide so as to
produce a cop with a flattened or slightly rounded bottom, the said means consisting
of the conical cam 1 operating in conjunction with the sliding jack and pivotted
stock v moved by the slotted plate z and pin whereby as the formation of the cop
bottom proceeds a minimum traverse is increased to a maximum traverse and the
required flattened or slightly rounded cop bottom produced substantially as described
and illustrated on Sheets 1 and 2 of the drawings.
(4) The improved means for modifying the traverse of the yarn guide so as to produce
a cop with a flattened or slightly rounded bottom, the said means consisting of the
conical catn 31 operating in conjunction with the pivotted yarn guide 65 carried by a

the formation of the cop bottom proceeds a minimum traverse is increased to a
maximum traverse in the manner and by the means substantially as described and
illustrated with reference to Sheet 3 of the drawings.
(5) The iinproved means for traversing the yarn guide a and for varying the
traverse of the same so as to produce a cop with a flattened or slightly rounded bottom,
the said means consisting of the excentrically carried cam dise 4 operating the strut 4

consisting of the finger p capable of being operated when the yarn breaks by the
cam ? so as to move the lever m thereby slackening the driving band and releasing
and applying the brake o and shifting the lever m so as to throw out of action the
frictional gear which operates the rack and pinion all substantially as described and
as illustrated with reference to Figs. 1, 2 and 4 of the drawings.
