Improvements in Yarn-winding Machinery.
We JOHN DEMPSTER WHYTE of 8 South Parade, in the City of Manchester,
Yarn Agent, and JOSEPH CLAY WEBSTER and JOHN HENRY WEBSTER of
Bridge Street, Buxton, in the County of Derby, Machinists, do hereby declare the
nature of this invention to be as follows:-
Our invention relates to cop-winding frames that is to say to machinery for
winding yarn into cop form. In our improved apparatus each spindle is mounted
to have an endwise movement in the direction of its axis in addition to its
revolving motion and we provide means whereby such endwise movement may be
readily regulated. The yarn to be wound supports a drop wire as the yarn
passes to the spindle. The cop is built up by the action of a vibrating thread
guide which is attached to a rocking shaft which may serve for all the spindles
on one side of the frame. The arc of vibration of the thread guide is inclined
with relation to the axis of the spindle so that the guide approaches the nose of
the cop and the guide moves toward the spindle. The rear end of the spindle
is acted upon by a rocking lever or crank arm which imparts to the spindle
the aforesaid endwise movement. The regulation is effected by moving the point
of connection with the lever toward or from the centre of movement of the lever.
In one arrangement one end of a connecting link or pair of links is coupled to
the end of the spindle the other end being jointed to a block or carriage which
is fitted to slide upon the lever or within a slot in the same and is adjustable by
means of a screw. A number of levers may be mounted upon a shaft to which a

Improvements in Yarn-winding Machinery.
We-JOHN DEMPSTER WHYTE of 8 South Parade, in the City of Manchester,
Yarn Agent, and JOSEPH CLAY WEBSTER and JOHN HENRY WEBSTER of
Bridge Street, Buxton, in the County of Derby, Machinists, 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 invention relates to cop-winding frames that is to say to machinery for
winding yarn into cop form. In our improved apparatus each spindle is mounted
to have an end wise movement in the direction of its axis in addition to its
revolving motion and we provide means whereby such end wise movement may
be readily regulated. The yarn to be wound supports a drop wire as the yarn
passes to the spindle. The cop is built up by the action of a vibrating thread
guide which is attached to a rocking shaft which may serve for all the spindles
on one side of the frame. The arc of vibration of the thread guide is inclined
with relation to the axis of the spindle so that the guide approaches the nose
of the cop as the guide moves toward the spindle. The rear end of the spindle
is acted upon by a rocking lever or crank arm which, imparts to the spindle
the aforesaid end wise movement. The regulation is effected by moving the point
of connection with the lever toward or from the centre of movement of the
lever. The aforesaid drop wire when released puts in motion parts which effect
the stoppage of the winding.
We may vary the parts for guiding the yarn. For guiding the yarn we employ
an oscillating disc or carrier acting upon a guide similar in formation to the
traveller used in ring spinning. We propose to mount the spindles to revolve
upon horizontal axes but we do not confine ourselves in this respect. In place of
the said lever we may use a piston and cylinder the piston or the cylinder being
coupled to the spindle end and being moved to impart the end wise movement of the
spindle by admitting liquid at a suitable pressure to the interior of the cylinder
the rate of the flow of such liquid determining the speed of endwise movement.of
the spindle.
The nature and object of our invention will be most clearly understood when
described with reference to the accompanying drawings.
In the said drawings
Fig. 1 represents an end view of a winding frame constructed in accordance with
our invention ordinary parts not necessary to the sufficient illustration of our
invention not appearing in the drawings.
Figs. 3 and 4 illustrate modifications which may be made in the apparatus.
In Fig. 1a is a spindle is the said rocking lever c is the vibrating thread
guide and d is the drop wire. The spindle a is mounted to revolve in a carriage.e
which is fitted to slide upon a lever f. This lever is mounted upon a rod g
which runs from end to end of the frame or thereabouts and would carry, a series
of similar levers cach lever carrying a spindle carriage with its spindle. The
carriage e slides also upon a rod which keeps the carriage upright and retains
it upon the lever but the method of mounting the carriage upon the lever is
immaterial so long as the carriage is retained upon the lever with freedom to slide
to and fro in the direction of the axis of the spindle. The spindle is provided with
a band pulley a' which is long enough to permit of the carriage moving the distance
required for the building of a cop as will be hereinafter explained.
·
To the rear end of the carriage e is hinged one end of a link which is connected
by its other end with a nut-carriage i which is fitted to slide up and down upon
the rocking lever b. A screw is mounted in the said rocking lever and engages
with the nut of the nut carriage i the 'said' nut extending into a slot in which the
screw is mounted. By turning the said screw the nut carriage can be shifted

page_text: nearer to or further from the fulcrum of the rocking lever. This fulcrum is carried
by a short arm of the lever so that the lowering of the arm which carries the
carriage e would lift the rocking lever. The lower end of the rocking lever is
formed as a quadrant and rests upon a wheel which is mounted upon a shaft l
this shaft being provided with as many wheels corresponding to as there are
spindles in the frame. Upon one end of the shaft is fixed a worm wheel in which
engages with a worm m¹ upon a shaft n. Upon the lower end of the shaft is fixed a
worm wheel o which engages with a worm o' which is fixed upon the shaft p which
drives all the spindles. The worm and wheel gearing imparts a slow revolving
motion to the shaft and the wheel & acting upon the quadrant imparts a slow
turning or rocking movement to the lever b. This movement is so regulated as
that the lever shall make one complete movement in the direction indicated by
the arrow during the building of the cop. Upon the shaft are fixed the
band pullies which drive the spindles. In the example the band passes over a
pulley which revolves upon à fixed stud and is used to deflect the leading
part of the band into a direction at right angles with the axis of the spindle.
The arrangements for driving the spindles may be varied. Upon the same
shaft p is fixed a pulley which drives a second pulley which is attached to
an excentric these parts being indicated by dotted lines. This excentric imparts
a rocking movement to a shaft c which extends along the frame so as to serve for
all the spindles. This rocking shaft carries a vibrating thread guide and also
carries a series of such guides to act in concert with the other spindles. The
action of this guide is illustrated by the detached Fig. 2. The arm which is
formed at its end to act as a thread guide vibrates to and fro through the limits
indicated by the dotted lines so that the thread guide moves in the arc 1, 2, the
parts being so arranged as that the cord of this arc shall be as near as may be
parallel with the side of the conical end of the cop as in the Fig. As the thread
guide vibrates it guides the yarn and causes it to be wound in the conical form
upon the spindle.
Another method which we may use for guiding the yarn is illustrated by Fig. 3.
In this example an excentric wheel 3 is fixed upon a revolving shaft and is so
formed as that the plane of its rim is inclined with respect to the axis of revolution.
The wheel is formed with a beaded rim upon which is mounted a bent wire which
is in the form of an ordinary ring traveller and serves as the thread guide. The
inclination of the wheel combined with the excentricity of the same are proportioned
to have the effect of moving the thread guide to and fro between the points 1 and 2
so that the yarn is wound upon the spindle in the required form and the guide is
kept at all times near to the surface of the conical cop end.
The lever with the carriage e tend to drop if not supported. In the example
the lever is supported by a prop s which forms one arm of a bell crank lever which
is mounted to turn upon a stud or upon a rod the other arm s¹ being connected by a
links with a levers which is mounted to turn upon a rod and is attached to or
formed in one piece with a second lever which is jointed at s to the drop wire d.
A lever is fixed upon a shaft u¹ which carries a series of knocking off catches o
one for each spindle. The lever u is connected by a link u² with an excentric u³ on
the shaft p whereby a rocking motion is imparted to the shaft u and as a
consequence the catches are caused to vibrate to and fro. So long as the drop
lever is sustained by the unbroken yarn a projection at d on the drop wire clears
the catch v but when the yarn breaks the end d' rises and is caught by the catch e
the result being that the drop wire is pulled over in the direction. indicated by the
arrow whereby the lever 3 is turned upon its axis and the connected lever's sis
also turned. This turning of the levers s' by moving the prop out of the
perpendicular permits the lever arm to drop slightly the result being that the
band is slackened and ceases to drive the spindle and also the quadrant ² is
lifted out of contact with the wheel k. When the apparatus is set to work the
carriage'e is brought over to the limit of its forward movement toward the outer

page_text: end of the lever arm the rocking lever inclining toward what would be the left
hand in the drawing. The yarn being attached to the spindle and the frame started
the winding on commences the yarn being laid by the guide c. As the winding on
proceeds the spindle is slowly drawn backward toward the fulcrum of the lever f
the speed of such movement governing the building of the cop which would be
finished when the carriage e had reached the end of such backward movement.
It
is necessary that the rate of movement of the spindle carriage relative to the
number of revolutions of the spindle should be capable of regulation. This is
effected by moving the carriage i by turning the screw as herein before described.
It will be seen that when the carriage i is moved nearer to the fulcrum 'the speed
of the spindle carriage will be reduced and on the contrary when the carriage i is
shifted toward the upper end of the lever the speed of the spindle carriage will be
increased. In the event of the breakage of the yarn the lever arm would be
'dropped in the manner hereinbefore described whereby the revolutions of the
spindle would cease and also owing to the lifting of the lever 6 the movement of
the carriage e would also cease. On the yarn being pieced the action of the parts
would be resumed. We do not confine ourselves to the horizontal positions of the
spindles nor to the arrangements for stopping the action of the parts on the
breakage of the yarn. We have shown means for the purpose to render the apparatus
more practically complete but we do not consider the stop motion to be an important
part of our invention.
Fig. 4 illustrates the alternative method of imparting the slow movement to the
spindle carriage e. In this example the rear end of the spindle carriage is connected
with the outer end of a piston rod w which is attached by its inner end to a
piston which slides in a hydraulic cylinder 2. Water or other suitable fluid is
conveyed under pressure by means of a pipe a into the space in front of the piston
and pushes the latter slowly toward the rear end of the cylinder thereby drawing
the spindle carriage in the direction indicated by the arrow. A great fluid pressure
is not required but the pressure should be uniform as for example the pipe a may
be connected with a cistern in which water or liquid would be maintained at a
constant level. The flow of water is regulated by means of a suitable valve so that
the rate of movement of the carriage e is made suitable to the formation of the cop
as in the first example. The speed for different counts of yarn would be regulated
by means of the said valve. In the example the lever of the regulating valve al is
connected by a rod with the prop s which sustains the lever. This rod can be
regulated in length by means of a right and left hand screw nut ³ or by other
suitable means so as to permit the valve to be more or less open when the prop is
brought into its upright position. When the prop would fall over to lower the
lever as herein before described the valve a¹ would be shut.
