Improvements in Machinery' for Winding Thread or the like.
I, ALGERNON DEWHURST, Director of John Dewhurst & Sons Limited of
Skipton in the County of York, Cotton Spinners and Sewing Cotton Manufacturers
do hereby declare the nature of this invention to be as follows:-
My invention relates to machines for winding thread or the like into coils cops
or cylinders or onto bobbins spools or tubes or the like and more particularly to
machines in which the thread or the like is wound in spiral form of coarse pitch,
that is with what is known as a quick traverse, and in which the speed of the
traverse is caused to bear a uniform ratio to the speed of the winding spindle by
means of regulating devices, for example by change wheels such as are employed
in the machines for which Letters Patent were granted to me dated 6th day of
May 1885 No. 5609, or in which the speed of the traverse as compared with that
of the winding spindle is caused to increase as the coil increases in diameter and
my invention has for its object to provide means whereby the thread can be
traversed to and fro from one extreme side or end to the other side or end of the
cop, coil, cylinder, or the like without any vibrating or reciprocating movement
of the thread guide thereby reducing wear and tear I provide a rotary thread
guide in combination with means for giving to the said guide a rotary movement
by positively driving it from the same source as that from which the winding
spindle or spindles is or are driven.
I will describe my invention as applied to a machine for winding coils or
cylinders of thread such as is described in the Specification to the Letters Patent
hereinbefore referred to, from which its application to other machinery of a
similar kind will also be readily understood. In this machine two spindles, which
I call the front and back winding spindles, are employed arranged in axial line one
with the other and between which the coil of thread is wound. According to my
present invention the thread is conducted to the spindle, tube, spool, or bobbin on
which it is to be wound, by the aforesaid rotary thread guide, the end of the
thread being secured to the said spindle, tube, spool, or bobbin, by any suitable
retaining device so as to cause the thread to be wound on the said spindle, spool,
or the like, when the spindle rotates. The said thread guide consists of a disc or
cylinder in one or more parts having in its periphery a cam groove or space so
shaped that the thread, which is placed therein is by the rotation of this disc or
cylinder (without any longitudinal movement being given to the thread guide)
caused to traverse to and fro from side or end to side or end of the coil and to lay
the consecutive spirals of thread parallel and close together. The thread guide is
mounted on a short spindle carried by an arm (or by arms rigidly connected
together) loosely mounted on a counter shaft arranged parallel to the winding
spindles. The arm or arms may be connected by means of levers and connecting
rods or by eccentrics or by levers connecting rods and eccentrics to a loosely
revolving presser arranged to bear on the coil as it is being wound, which presser
by leing connected to the thread guide maintains the said thread guide at a
suitable distance from the coil as it is being made the connection being such that
as the coil increases in diameter and forces the presser further from the axis of the
winding spindle the thread guide will be moved correspondingly away from the
axis of the said winding spindle.
.

page_text: For operating the rotary parts of the machine any suitable arrangement of
gearing may be employed and change wheels or other convenient means may be
provided for varying as required the relative speeds of the thread guide and
winding spindles. A suitable arrangement of driving gear consists as follows:-
On the winding spindle is a pulley round which passes a driving strap from any
suitable motor. The winding spindle carries a pinion gearing with a broad carrier
wheel mounted on a stud on an adjustable plate or bracket with which carrier
wheel also gears a spur wheel on a counter shaft from which, by means of gearing,
rotation is given to the thread guide. The gear wheels by which motion is
transmitted from the winding spindle to the counter shaft are change wheels so
that wheels of suitable sizes may be fitted to vary the speed of rotation of the
thread-guide with relation to the speed of rotation of the winding spindle so as to
cause the thread to be moved to and fro from side or end to side or end of the cop
spool or cylinder of thread er the like in such a manner that whatever may be the
thickness of the thread or the like to be wound each right hand spiral can be laid
in close juxtaposition to the preceding right hand spiral and each left band spiral
can be laid in close juxtaposition-to the preceding left hand spiral.

Improvements in Machinery for Winding Thread or the like.
I, ALGERNON DEWHURST, Director of John Dewhurst & Sons Limited, of
Skipton, in the County of York, Cotton Spinners and Sewing Cotton Manu-
facturers, 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 machines for winding thread or the like into coils, cops
or cylinders or onto bobbins, spools or tubes or the like and more particularly to
machines in which the thread or the like is wound in spiral form of coarse pitch,
that is with what is known as a quick traverse, and it which the speed of the
traverse is caused to hear a uniform ratio to the speed of the winding spindle by
means of regulating devices, for example by change wheels such as are employed
in the machines for which Letters Patent were granted to me dated 6th day
of May 1885, No. 5609, or in which the speed of the traverse as compare:l with
that of the winding spindle is caused to increase as the coil increases in diameter
and my invention has for its object to provide means. whereby the thread can be
traversed to and from one extreme side or end to the other side or end of the cop,
coil, cylinder or the like without any vibrating or reciprocating movement of the
thread guide thereby reducing wear and tear. I provide a rotary thread guide in
combination with means for giving to the said guide a rotary movement derived by
positively driving it from the same source as that from which the winding spindle
or spindles is or are positively driven.
I will describe my invention as applied to machines for winding coils or
cylinders of thread such as are described in the Specification to the Letters Patent
hereinbefore referred to from which its application to other machinery of a similar
kind will also be readily understood. In this machine two spindles, which I call
the front and back winding spindles, are employed arranged in axial line one with
the other and having cheek pieces thereon between which the coil of thread is
wound upon the reduced end of one of the said spindles.
According to my present invention the thread is conducted to the spindle, tube,
spool, or bobbin on which it is to be wound, by the aforesaid rotary thread guide

page_text: the end of the thread being secured to the said spindle, tube, spool, or bobbin, by
any suitable retaining device so as to cause the thread to be wound on the said
spindle, spool, or the like, when the spindle rotates. The said thread guide consists
of a dise or cylinder in one or more parts having in its periphery a cam groove or
space so shaped that the thread, which is placed therein, is by the rotation of this
disc or cylinder (without any longitudinal movement being given to the said disc or
cylinder) caused to traverse to and fro from side or end to side or end of the coil
and to lay the consecutive spirals of thread parallel and close together. The thread
guide is mounted on a short spindle carried by an arm (or by arms rigidly connected
together) loosely mounted on a counter shaft arranged parallel to the winding
spindles. The arm or arms may be connected by means of levers and connecting
rods or by eccentrics or by levers connecting rods and eccentrics to a loosely
revolving presser arranged to bear on the coil, as it is being wound, which presser
by being connected to the thread guide maintains the said thread guide at a suitable
distance from the coil as it is being made the connection being such that as the
coil increases in diameter and forces the presser farther from the axis of the winding
spindle the thread guide will be moved correspondingly away from the.axis of the
said winding spindle. For operating the rotary parts of the machine any suitable
arrangement of gearing may be employed and change wheels or other convenient
means may be provided for varying as required the relative speeds of the thread
guide and winding spindles. A suitable arrangement of driving gear consists as
follows: On the winding-spindle is a pulley round which passes a driving-strap
from any suitable motor. The winding-spindle carries a pinion gearing with a
broad carrier wheel mounted on a stud on an adjustable plate or bracket with
which carrier wheel also gears a spur wheel on a counter shaft from which, by
means of gearing, rotation is given to the thread guide. The gear wheels by
which motion is transmitted from the winding-spindle to the counter shaft are
change wheels, so that wheels of suitable sizes may be fitted to vary the speed of
rotation of the thread guide with relation to the speed of rotation of the winding
spindle so as to cause the thread to be moved to and fro from side or end to side or
end of the cop, spool or cylinder of thread or the like in such a manner that
whatever may be the thickness of the thread or the like to be wound, each right
hand spiral can be laid in close juxtaposition to the preceding right hand spiral and
each left hand spiral can be laid in close juxtaposition to the preceding left hand
spiral.
In order that my invention may be clearly understood I shall further describe
the same with reference to the accompanying drawings,
Figure 1 of which is a side elevation and Figure 2 a corresponding plan of a
hand winding machine constructed according to my invention, for making one
coil, cop or cylinder at a time or for winding onto one bobbin, spool or tube
at a time.

are in
Figures 10 and 11 are respectively a front elevation and a transverse sectional
elevation of a portion of the machine, showing more clearly the thread guide with
its divided cap or cover, the thread cutter and thread retaining device, also the
sloping delivery trough or shoot, Figure 11 showing also the position of the winding
spindle, and
Figure 12 represents a plane projection of the cams showing the relative
positions of the cams' surfaces for effecting the various motions hereinafter
described.
Figures 13, 14 and 15 are respectively a side elevation, a plan, and an end
view of the principal parts of a winding machine constructed substantially in the
same manner as that described with reference to Figures 1, 2, 24, 3, 4 and 5,
but on a much smaller scale so as to render it suitable as an attachment to a
sewing machine.
The hand machine represented by Figures 1, 2, 24, 3, 4 and 5 may be used for
winding thread or the like into coils, cops or cylinders or the like either with or
without central tubes and may be bolted or otherwise fixed upon an ordinary table
for hand spooling and may be driven from any suitable prime mover by means of
a strap or tape passing round the wharve or pulley a fast on the front winding
spindle A which is fitted to rotate in bearings 6 in the frame B of the machine.
In axial line with the spindle A is mounted in bearings 62 the back winding
spindle A2 which is driven at the same speed as and from the front spindle A
by means of the gearing and shaft D. One end of the back spindle A² is
reduced in diameter as shewn at a² to correspond to the size of the hole or
passage to be left in the centre of the coils or rolls of thread to be formed on
which reduced portion, which may, if so desired for winding upon tubes, be con-
structed with expanding springs or other expanding apparatus, the thread is
wound between two cheek pieces, collars or heads E E2 mounted respectively on
the adjacent ends of the front and back spindles. These cheek pieces, collars or
heads are fitted so as to rotate with their spindles. The cheek piece E2 is
provided with a hole or passage in its centre through which hole the reduced
portion a² of the spindle A2 projects and enters a recess in the face of the cheek
piece E the distance between the faces of the two collars or cheek pieces being
equal to the thickness or length of the coil or roll of thread to be formed.
G is a thread guide which consists of a disc having in its periphery a cam groove
or space o to receive the thread to be wound. This guide is fast on a spindle or
shaft H mounted in bearings h in arms 2 connected together by a bar h³ so as to
form a rigid frame which frame is mounted loosely on a shaft H2 arranged parallel
to the winding spindles A A2 and mounted in bearings in the frame B and a
bearing in a bracket bolted to a plate B2 secured to the said frame.
The spindle or shaft H and the shaft H2 are connected together by gearing .
On the shaft H2 is a spur wheel gearing with a broad carrier pinion ³ mounted
loosely on a stud 10 on an adjustable bracket ¹¹ bolted to the frame B of the
machine.
.
Gearing with the broad carrier pinion is a spur wheel 12 on the front winding
spindle A. The wheels 12 are change wheels whereby the relative speeds of the
winding spindles A A² and the spindle or shaft H carrying the thread guide G may
be varied as required. K is a disc preferably of slightly greater diameter than
the thread guide G the said disc being carried so as to rotate on an axis k³ in
arms fast on a rocking shaft K mounted in a bracket bolted to the frame B
and in a bracket bolted to the plate B². On the shaft K2 is also fixed another
arm provided with a handle by means of which the shaft may be turned in its
bearings in the brackets kk so as to cause the disc K to press on the thread as it
is being wound on the reduced portion a² of the spindle A2. The length of the

page_text: arms k from the centre of the disc or presser K to the axis of the rock shaft K
is the same as that of the arms ² from the centre of the thread guide G to the axis
of the shaft H² the position of the rock shaft K2 being such that it and the shaft H2
are equidistant from the axis of the winding spindle. Connected to the frame ³ ³
is an arm hinged at to one end of a rod or bar the opposite end of which rod
or bar is by means of a stud forming part of the handle connected to the arm (3
on the shaft K. The length of the arms and are equal to one another and the
length of the connecting bar or rod is equal to the distance between the axis of
the shafts H2 and K2 thus it will be seen that the imaginary lines K2, 6, H²,
and H2 K2 form a parallelogram and that the arms and connections, of which three-
sides of it are composed, move together in such a way that the angle H H' A is
always equal to the angle 3 K2 A so that as the disc or presser K is moved further
from the axis of the winding spindle by the coil of thread as the said coil increases-
in diameter the thread guide G will be correspondingly moved further from the
said spindle and so during the winding process be constantly kept just out of
contact with the coil. In order to ensure great accuracy of the movement of the
presser and the thread guide to and from the winding spindle I prefer to apply an
additional connection between the shafts H2 and K2 the said connection consisting
of an eccentric 3 on the frame h2 h of which eccentric the strap 4 forms part of a
connecting bar 15 which at its other end forms also the strap 16 of another
eccentric fast on the rock shaft K2 the lines of greatest throw in the two.
eccentrics being parallel one to the other and pointing in the same direction.

f2 is a hand wheel fast on a screwed stem F3 working in a stationary nut or
internally screwed boss F formed on the plate B' bolted to the frame B. On a
plain or unscrewed part of this stem is loosely mounted, between the boss of the
wheel and a collar on the said stem, an arm F provided at its upper end with a
hollow boss f3 in which the outer end of the back winding spin.lle A rotates. In
the portion of the spindle A2 which enters the hollow boss f³ is formed an annular
groove or recess with the sides of which engages the end of a set screw f* screwed
through the side of the said hollow boss. The engagement of this set screw with.
the sides of the annular groove or recess causes the said spindle to move longi-
tudinally with the movement of the screwed stem F³ and carm F, but nevertheless
admits of the rotation of the spindle in the said boss f³. The distance to which
the back spindle A² can be moved longitudinally is governed by the head of a stud f5
which stud passes through a hole in the arm F and screws into the plate B' the
distance to which the stud is made to project beyond the arm F' regulating the
extent of the longitudinal movement of the spindle. On the spindle A² is
provided a longitudinal groove f' (see Figure 24) to receive a key fixed in the
interior of the cheek piece E2 so as to cause the said cheek piece to revolve with
the said spindle although admitting of the longitudinal movement of the said
spindle in the said cheek piece. The cheek piece E2 is moved away from the
cheek piece E by the outward longitudinal movement of the spindle A³ until the
rear end of the said cheek piece E2 comes into contact with a shoulder in
the interior of the bearing 6 whereupon the movement of the cheek piece is
arrested and the spindle by its continued movement draws the reduced end a³
thereof into the cheek piece E' and so releases from the machine the coil of thread
when wound.
In commencing to form a coil or roll of thread the thread from the thread supply
is laid in the cam groove or space y of the thread guide G and the end of the
thread is secured between the contiguous ends of the front and back spindles A A³..
The thread guide G is then by means of the handle brought into position between
the cheek pieces E E². The machine is then started in the ordinary manner by
friction gearing worked by a treadle or otherwise whereupon the spindles A A
will rotate and wind the thread upon the reduced portion a³ of the back spindle A²..
When the coil has reached the required diameter the thread guide is removed from
between the cheek pieces by means of the handle, the thread is severed, the
cheek pieces E E' are separated one from the other by means of the hand wheel fs.
.

page_text: and as the motion of the hand wheel is continued the reduced end of the spindle A³
is withdrawn from the centre of the coil which being released falls from the
machine into a suitable receptacle.

Figures 6 and 7 illustrate a modified form of the machine herein before described
and in which modified machine the use of the back winding spindle and its cheek
piece are dispensed with, and the cheek piece E is fitted to slide longitudinally on
the spindle A for the purpose of forcing from its reduced end a² the coil of thread
or the like when wound. The sliding movement of the cheek piece E is effected
by means of a lever handle F2 hinged at fx to the base of the machine, the said
lever being connected by a link d³ to a sliding bar Fe provided with a projection fo
which engages the sides of an annular groove or recess formed for the purpose in
the periphery of the cheek piece E so that by moving the lever handle F in one
direction or the other a corresponding movement can be imparted to the said
check piece. The bar Fe slides in an opening provided for the purpose in the
frame B.
In the arrangement illustrated by Figures 6 and 7 the brackets h and ke are
shown attached to a portion of the framework B which is for the purpose carried
up somewhat higher than usual.
Referring to Figures 2 and 20 which illustrate a modification in the construction
of the check pieces and of the contiguous ends of the winding spindles A. A² for
winding thread or the like onto spools, one of which is illustrated by Figure 2D,
the contiguous faces of the cheek pieces E E' are respectively formed with
recesses 2² to receive the correspondingly shaped ends of the spool upon which
the thread is to be wound: In the sides of the aperture in the centre of the cheek
piece E2 are one or more longitudinal slots 3 to admit of the passage of one or
more projections provided on the spindle A2 for the purpose of engaging with
the surface of one end of the spool to ensure its rotating along with the winding
spindles.
Although in the drawings 1, 2, 24, 2º, 2º, 3, 4 and 5 I have illustrated an
arrangement wherein the check piece E2 and the spindle A2 receive longitudinal
movement I do not restrict myself to this arrangement as it is obvious that the
cheek piece E and spindle A may be arranged to move in place thereof or in
combination therewith.
The self acting machine of which Figures 8-12 show certain portions, is one
of the Weild type modified in several respects, as described in the Specification to
the Letters Patent herein before referred to.
In applying my invention to self-acting machines I may arrange any desired
number of spindles in one machine and rotate them from one driving shaft. I have
however shown in Figure 8 of my drawings only one pair of spindles and, in order
to prevent unnecessary complication, I have omitted from the drawing various
details and parts common to such machines but which are or may be used in
combination with my improvements.
-
Referring to Figures 8, 9, 10 and 11 B is a portion of the framework of the
machine, A A2 are respectively the front and the back winding spindles rotating
respectively in bearings b b and fitted with collars or cheek pieces EE as in the
hand machine herein before first described, a² is the reduced portion of the front
spindle A upon which I prefer, in the case of a self-acting machine, to wind the
coil or roll of thread or the like, D the driving shaft, CC the gearing for
rotating the winding spindles, G the rotary thread guide, H the spindle or shaft
which carries the thread guide, the bearings of the said spindle or shaft, h² the
arms in which it is carried, h³ the bar which connects the said arms so as to form
a rigid frame like that which I have described in connection with the hand
machine, H2 the shaft upon which the said rigid frame is loosely mounted, h* the
bearings of the shaft H2 in the framework B and B³, ' the gearing which connects
the shaft H2 with the spindle or shaft H, the spur wheel on the shaft H2
gearing with a carrier pinion ³, 10 the stud which carries the said pinion, the
adjustable bracket by which the stud 0 is attached to the framework B³ of the

page_text: beadstock at the end of the machine, 2 a wheel upon the driving shaft D by
means of which motion is imparted to the carrier pinion and through it to the
spur wheel and the guide G the wheels h³ 12 being change wheels whereby the
relative speeds of the winding spindle A and the spindle or shaft H carrying
the thread guide G may be varied as required, the cam groove or space to
receive the thread to be wound, a divided cap or cover which I prefer to place
over the rotary thread guide in order to prevent the thread from slipping off it
sideways while the spindles are stationary the said cap or cover being attached to
the rigid frame 123 by means of screws g or by some other convenient device ;
K the presser which acts upon the thread while it is being wound up on the
reduced portion a² of the driving spindle A, ³ the axis on which the presser K
revolves, the arms which carry the presser K the said arms being fast on the
rockshaft K2 which I prefer, in the case of a self-acting machine, to make hollow
and to mount loosely upon the sliding rod w³ a portion of the said rockshaft being
cut away as shown in Figure 9 to allow sufficient room for the horizontal movement
of the hooked wire w² which is also mounted on the rod w³ and to allow the rock
shaft to make a partial revolution without its coming in contact with the hooked
wire, is the arm which in the case of the hand machine herein before first
described is provided with a handle but which in the case of a self-acting machine
need not he so provided, the arm connected to the frame 23, is the bar
which forms the connecting rod between the arms and which bar carries at
one end a stud by means of which it is hinged to the arm the said bar being
at its other end hinged to the arm by means of a stud and also to a link the
forked end of which carries the aforesaid stud there being in the underneath
portion of the said link 8 a curved notch or opening (shown in dotted lines in
Figure 9) the curve of which notch has the stud for its centre and the said
notch engages a stud 10 carried by the forked end of an arm fastened by a set
screw to the shaft the connection being such that, when the aforesaid notch is
engaged with the aforesaid stud, the presser, and along with it the guide, can, by
a partial revolution of the aforesaid shaft 12 in one direction, be moved away
from the winding spindle or can, by the shaft being permitted to make, under the
action of the customary spring or weight, a partial revolution in the opposite
direction, be moved closer to the winding spindle, and, when the link 8 is raised
so as to disengage the notch from the stud 10, the presser and the guide can be
moved by hand to facilitate the piecing of a broken thread or for any other
purpose, the eccentric on the rigid frame 23, the strap of the said eccentric,
17 the eccentric on the rockshaft K2, the strap of this latter eccentric, ¿¹ the
connecting bar between the two eccentrics.
Gearing with the spur wheel ³ there is, in addition to the carrier pinion.
already described, a second carrier ¹³ mounted upon a stud 14 attached to an
adjustable bracket which is bolted to the framework B³ of, the headstock at the
end of the machine. Gearing with the said second carrier 13 is a spur change
wheel mounted upon the shaft P2 which, as is customary in Weild's self-acting
spooling machines, is made with right and left hand screws upon it for traversing
the shaper finger backwards and forwards across the shaper plate. The shaper
plate and the shaper finger, which are not shown in my drawings, are made like
those in other machines of the Weild type, but, as in this machine, there is not a
traverse rod for the sliding rocker P³ to operate, it is mounted loosely upon the
shaft H2, the position of which in the headstock is, in order to suit the arrange-
ment of the other portions of the machine, somewhat lower down than the usual
position of the traverse rod in ordinary machines; the rocker arms P+ being
correspondingly longer than usual and the shaper plate being placed somewhat
lower than customary in order that it may be upon a level with the centre of the
shaft H2 and consequently on a level with the axis of the rocker P³.
From the sliding rocker P3 is actuated the second rocker P³ to which is attached
the usual pawl P which actuates the ratchet wheel P7 (shown in dotted lines in
Figure 8) and thus causes the ratchet wheel shaft P to gradually rotate with an

page_text: intermittent motion while the winding is in progress. The wheel 1 being as
already described a change wheel, it is possible by means of it to regulate the
speed at which the screw shaft P2 rotates and consequently the number of times
that the shaper finger traverses across any given shaper plate for a certain number
of revolutions of the shaft H2 and for a certain number of revolutions of the driving
shaft D.
As is customary with machines of the Weild type, each time the shaper finger makes
a backward and forward movement across the shaper plate the pawl Po attached to the
rocker P³ moves the ratchet wheel forward one tooth and, when the last tooth is being
acted upon, the winding portion of the machine is brought to a standstill and the
cam portion for performing the other operations is set in motion. The shaper plate
being changeable, also to a limited extent adjustable, and the ratchet wheel P7 and
the spur wheel 16 being change wheels, it is possible by selecting a shaper plate of
the right form and wheels with the requisite number of teeth, to regulate the
number of revolutions that the winding spindle makes during the winding of each
cop, or the like, and consequently the length of thread wound.
k is a loosely revolving presser situated beneath the winding spindle, and
supported by a forked stem ³, the said presser being under the action of a
spring operating upon the said stem brought into contact with the coil of thread
or the like after it has been wound and for the purpose of squeezing down upon
its surface the loose end of thread after the severing of the coil from the thread
supply. For the purpose of holding the presser out of action until it is required
to press upon the coil there projects from stem a stud 4 carrying a bowl k
which is acted upon by a wedge shaped block mounted upon the sliding rod k
which is operated by cam No. 5.
Further, as described in the herein before mentioned Specification, ² are the
rounded nicks in the collar or cheek piece E, e the spring catches or clips arranged
round the said collar or cheek piece, L the hook which during the winding process
disengages from the clip the starting end of the thread, 2, on the check piece E,
the groove into which the hook L enters, m² the spring acting upon the said hook,
m³ the wedge-shaped block for withdrawing the said hook, m² the sliding rod upon
which the block is carried, m³ the friction bowl against which the said block
presses, m the stem of the hook to which stem the said bowl is attached, m' the
spring by means of which the sliding rod m¹ and the wedge-shaped block upon it
are brought back into their normal position after having been operated by the cam
on the ratchet wheel shaft, M the hook which engages the thread between the coil
and the thread supply, N the spring plate between which and the said hook the
thread is drawn, O the stationary cutter on the opposite side of the said hook,
the instrument by means of which the finishing end of the thread is disengaged
from the rounded nick and laid snugly upon the periphery of the coil, ² the
annular groove which is made in the circumference of the collar or cheek piece E
and into which the instrument a descends, the rod for operating the cheek pieces,
d³ the link through which the said rod acts, F2 the lever acting upon the cheek
piece E, F the lever acting upon the cheek piece E², d and d² the thrust pieces by
means of which the cheek piece E2 is caused to move forward for a certain
distance at the same speed as the cheek-piece E and then at a more rapid rate in
order to increase the space between them and to liberate the coil, p the sloping
trough or shoot by which the coil is conducted into a suitable receptacle, c the
helical spring under the action of which the cheek pieces return to their normal
position ready for winding a fresh cop or the like and which keeps the cheek pieces
in that position during the winding process.
Referring to Figure 12 No. 1 shows in plane projection the cam for moving the
rotary guide and the presser connected to it away from the winding spindle after
a cop or the like has been wound and for causing the said guide and the said
presser to enter the space between the two cheek pieces when the machine is
preparing to wind a fresh cop.
No.

means of the hooked wire w³, been drawn across the path of the said hook M.
No. 4 shows in plane projection the cam for causing the instrument to enter the
groove and to turn the end of the thread onto the surface of the cop so that
when the few additional revolutions which I prefer to impart to the cop are in
progress the end of the thread will be neatly pressed down upon the periphery of
the cop
No. 5 shows in plane projection the cam for actuating the small compacting
presser which is only brought into play after the cop has been formed and just
before the commencement of the few extra revolutions which I have referred to.
No. 6 shows in plane projection the cam for causing the cheek pieces E E³ to
slide endways along their respective spindles A Ain order that the finished cop
inay be forced off the winding spindle.
No. 7 shows in plane projection the cam which causes the hooked wire w' to 'draw
the thread within reach of the hook M after each cop has been wound.
In commencing to wind a coil or the like the thread from the supply bobbin is
passed under the shaft 2, then laid in the nick or space between the two portions
of the divided cover 9' then drawn across the end of that half which is nearest to
the cheek piece E, thence into one of the rounded nicks in the collar or cheek
piece E, and the end of the thread is secured beneath one of the spring catches or
clips e arranged round the collar or cheek piece E. The thread having been thus
secured to the cheek piece E the winding mechanism is started and, as the
spindles A A2 and the guide G rotate, the thread is drawn into the cam groove or
space g in the periphery of the guide G and is wound upon the reduced portion á²
of the winding spindle A it being traversed rapidly to and fro from one side of the
opening between the two cheek-pieces to the other side of it by means of the cam
groove or space g³ in the periphery of the rotating guide G, each right hand spiral

as shown in my drawings, being parallel to the preceding right hand spiral, the
two being either in actual contact with one another or at a certain distance apart
as may be required, and each left hand spiral of thread after the first half.
revolution of the guide, if made with a double traverse, being parallel to the
preceding left hand spiral the proximity of the two corresponding with that of the
right hand spirals and being regulated by means of the change wheels and h¹²
which are made use of to determine how many revolutions the winding spindle shall
make for each revolution of the rotary guide. After the winding spindles have ¨¨
made a number of revolutions the detaching hook L actuated by the usual cam on
the ratchet wheel shaft enters the groove 12 engages the thread, between the
rounded nick e² and the spring catch e, thereby. pulling the starting end of the
thread from the hold of the said spring catch and setting free the starting end of
thread. Having performed this operation the detaching hook L is permitted by
its cam to return under the action of the spring m' to its normal position. When
the cop has acquired the requisite diameter or when the required length of thread
or the like has been wound, the winding portion of the machine is stopped in the
ordinary way by the escape plate or disc in the headstock of the machine being
liberated and allowed to make a partial revolution, the shaper plate and ratchet
wheel in the headstock having as previously explained been so arranged as to
bring this about at the right moment. The cam shafts being at the same moment
and by the same movement of the escape plate set in motion, the rotary guide and
with it the presser K are removed from between the cheek pieces, the hooked
wire then passes between the rotary guide and the coil nick, engages the thread
between the two and draws the said thread aside into the path of the hook M by
which it is drawn down against the spring plate N on one side of the hook and
gainst the stationary cutter O on the other side of the hook, the stationary cutter
evering the thread on the coil from the thread supply and the spring plate
etaining hold of the severed end of the supply thread. The coil having been
hus severed from the thread supply the winding mechanism may be, as described
B

page_text: in the Specification to the Letters Patent hereinbefore referred to, set in motion,
the loosely revolving presser k having been previously brought into contact with
the surface of the coil and the instrument a having been caused to descend into the
groove ². As soon as the winding spindles begin to revolve the said instrument
engages the finishing end of the thread, pulls the said thread out of the rounded 5
nicke and lays it snugly upon the surface of the coil where it is pressed down by
coming, as the cop revolves, in contact with the presser k. The winding spindles
after having made a few revolutions may as described in the Specification to the
Letters Patent herein before referred to, be again brought to a stand and the cam
shafts be permitted to complete the revolution which was interrupted. The
continued movement of the cam shafts causes the presser k to return to its normal
position and the cheek pieces to slide along their respective winding spindles
thereby pushing the cop off the small end a² of the winding spindle A. and allowing
it to drop down the sloping trough or shoot, the hooked wire and the instrument x
having in the meantime returned to their normal position. As the cams continue
to rotate the cheek pieces return to their normal position, the thread guide G and
with it the presser K enter the space between the said cheek pieces, the driving
belt is thrown onto the winding pulley and the winding spindles are set in motion,
one of the spring catches et having, as the winding spindles began to revolve,
engaged the starting end of the thread between the rotary guide and the point
where it was held by the spring plate N, and pulled the said thread away from the
hold of the said spring plate. The end of the thread being retained by the spring
catch the said thread is carried round by the winding spindle as it rotates and
the winding of a fresh cop commences.
In the machine represented by Figures 13, 14 and 15 the parts corresponding to
to those in the hand machines previously described are designated by the same
reference letters. It will be observed however that in this arrangement the back
winding spindle is omitted and the cheek piece E2 is attached to the spindle A by
a screw projecting from its centre and screwing into the reduced end a² of the
spindle A and is provided with a milled knob or handle e for convenience of
placing in position and withdrawing the said cheek piece and removing from the
spindle the coil when wound. It will also be observed that in place of the warve a
in the previously described machine a small friction pulley a is substituted therefor,
which by turning the whole machine on its supporting pivot 63 can be brought into
contact with the fly wheel or other suitable rotating part of the sewing machine
so as to drive the winding mechanism. It will further be observed that in place of
change wheels for varying the relative speeds of the thread guide and the winding
spindle a pair of cone pulleys 8 12 is provided for the purpose.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In machinery for winding thread or the like the employment of a rotary
thread guide having in its periphery a cam groove or space to receive the thread
to be wound in combination with means for giving to the said guide a rotary
movement by positively driving it from the winding spindle or spindles or from
the same source as that from which the winding spindle or spindles is or are
positively driven, substantially as herein before described.
2. In machines for winding thread or the like the combination of a rotary
thread guide having a cam groove or space in its periphery to receive the thread
to be wound and means for maintaining the said guide in close proximity to, but
just clear of, the surface of the coil or the like at it is being wound, substantially
as hereinbefore described.
3. In machines for winding thread or the like the combination with the rotary
thread guide having a cam groove or space in its periphery to receive the thread
to be wound of a disc or presser connected to the thread guide by arms and
connections constituting a parallel motion whereby as the presser is moved

page_text: outward from the winding spindle by the coil of thread or the like as it increases
in diameter the thread guide is simultaneously moved out from the winding spindle
in the same proportion so as to retain the said thread guide, out of contact with
the coil substantially as herein before described.
4. The combination and arrangement of parts constituting the machine for
winding thread or the like into coils, cops or cylinders or on to bobbins, spools or
tubes or the like in which the thread or the like is wound in spiral form of coarse
pitch with what is known as a quick. traverse and in which the speed of the
traverse is caused to bear a uniform ratio to the speed of the winding spindle by
means of regulating devices substantially as hereinbefore described with reference
to Figures 1 to 5 of the accompanying drawings.
5. The combination and arrangement of parts constituting the self acting
multiple machine for winding thread or the like into coils, cops or cylinders or on
to bobbins, spools or tubes or the like substantially as hereinbefore described and
illustrated by Figures 6, 7, 8, 9 and 10 of the accompanying drawings.
