I ALGERNON DEWHURST of the Firm of John Dewhurst and Sons of Skipton in
the County of York Cotton Spinners and Sewing Cotton Manufacturers do hereby
declare the nature of my said Invention for "IMPROVEMENTS IN MACHINERY FOR
WINDING COILS OF THREAD FOR USE IN SEWING MACHINES OR FOR OTHER
PURPOSE" to be as follows:-
The object of my Invention is to provide machinery or apparatus for making
coils of thread such as are wound without bobbins spools or holders and are
generally enclosed in cases from which the thread is drawn. They are suited for
use in Sewing Machines of the kind known as the "Singer oscillating shuttlo
machine" but of course the coils made by the apparatus may be used for any other
purpose to which they are adapted. The Invention may be of course applied to
either hand spooling machines or to self acting machines for example those of the
"Weild" type for winding a number of coils at the same time. I will describe the
Invention as applied to a hand machine from which its application to the larger
kind or self acting machines will also be understood.
The motion of the revolving parts of the machine may be obtained in the
ordinary way by the usual mechanism employed in winding thread on bobbins but
the front spindle is reduced or formed of a size and shape to suit the hole in the
centre of the coil to be wound. A loose collar or tube is arranged so that it can
revolve with and be slidden by a lever or otherwise longitudinally upon the front
spindle at the reduced end the end of the said loose collar or tube forming one of a
pair of cheeks between which the coil is wound and by which the flat or other shape
of the sides of the coil is obtained the other of the said cheeks being carried by the
back spindle arranged in line with the front spindle and driven at the same speed.
The last named cheek is pressed forward to its normal position by a spring but is
connected with the same device that gives longitudinal movement to the first
named cheek by a lever or thrust piece so arranged that when the first named
cheek piece is moved longitudinally the other cheek moves with it at the same rate
so as to maintain the coil between them whilst it is pushed from off the reduced
end of the spindle upon which it was formed but when this has been done the
continued movement is given only to one of the cheeks so as to move the one away'
[Price 11d1

page_text: from the other that the coil may drop from between the checks into a spout or
receptacle. One or the other of the cheek pieces carries hooks or has nicks inade
in it or equivalent retaining devices to hold the end of the thread and to carry it
round the reduced end of the spindle in commencing winding. A presser is
situated between the cheeks and presses upon and moves outwards with the thread
as it is wound but is retained out of action when the coil is thrust from the
machine. A thread guide for guiding and traversing the thread backwards and
forwards as each layer is wound may also be used. This may be of the ordinary
kind and be operated in the ordinary way.
I do not limit myself to the moving of the cheeks precisely as described as it will
be evident that the cheeks may be moved in either direction and that the reduced
end of the spindle may be itself withdrawn from the cheek instead of the cheek
being moved over it provided that the relative movements of the parts be obtained
for the purpose hereinbefore described for example only one of the cheeks may be
made moveable and the other stationary so that the reduced end of the spindle is
first withdrawn from the wound coil and then the moveable cheek is moved away
from the other cheek to liberate the coil. When the Invention is applied to a self
acting machine the arrangement will be substantially the same as that hereinbefore
described. In this case I may place any number of pairs of the spindles in suitable
bearings upon the table of the machine both the front and the back spindles being
rotated from the driving shaft of the machine. To give a sufficiently short
traverse of the guide rod for making the narrow coils of thread I may make the
shaper plate wider than the coil and I may place a lever at the end of the guide
rod to diminish the traverse of the rocking shaft the guide being so adjusted as to
move backwards and forwards without getting down into the coil nick. A guide
with only one groove having a pin across it may be used in place of the usual
guide with a number of grooves. In "Weilds" machine upon the back rod for
sliding the spindles I may fix an inclined plane to pull the presser away from the
coil before it is forced off the spindle To the front rod for sliding the spindle
I may attach a link for the purpose of operating the parts for allowing the coil to
drop out.
To slide both the back and the front rods I may apply new cams in the same
position as those in Weilds machine for working these rods but so formed as to
cause the presser to move out of the way before the front rod begins to push the
coil off the spindle and to keep the presser out of the way until the machine is
again ready for winding.
To catch hold of the starting end of the thread and to carry it round with the
spindle I may place one or more clips or springs or make one or more narrow nicks
on the surface of the collar nearest to the knife and on this collar and nearer to the
part where the coil is wound 1 may make a projecting ring with one or more
rounded nicks in it and I may make a groove in the surface of the collar and
encircling it between the clips holding the end of the thread and the projecting
ring. Into this groove I force a knife to cut off the starting end of the thread or
I may force a hook to pull the starting end of thread away from the clip so as to
leave the coil free to drop down the trough when the coil is released. To force the
knife or the book into the groove I may fix an inclined plane to the rod which in
Weilds machine moves the knife for cutting of the starting end of thread.
It is desirable that the coil of thread before being released from the machine
should have a few rotations given to it against the presser after the end of the
thread is cut so as to cause the said end to lie down well in its place. To effect
this I make in the disc on the ratchet wheel shaft which is at the back of Weilds
machine two notches at opposite sides of the disc and I attach an extra click or
pawl (or its equivalent) upon the arm turning upon the ratchet wheel shaft
and operated by an extra connecting rod moved by the cam shaft. This extra
pawl or the like when the cam shaft has made a portion of its revolution and the
knife has been made to act moves the ratchet wheel shaft and by that means
liberates the mechanism for putting the winding shaft again in rotation so that the

page_text: coil is rotated against the presser in order to make the loose end of the thread' lie
flat. That the belt may be again removed from off the winding mechanism
I throw gear into action at the same time that the belt is thrown ou again for
rotating the coil as described which gear quickly rotates the ratchet wheel shaft to
the position for again throwing the belt onto the pulley for turning the cam shaft
so as to cause it to complete the revolution it had commenced in order to prevent
the delay which would occur if the ratchet wheel had to be operated tooth by
tooth (as in winding) before the belt would be thrown off and I provide a cam on
the cam shaft in the head stock for holding a clutch box forming part of this gear
out of action during the ordinary winding operation of the spindle and I further
provide a cam on the ratchet wheel shaft for throwing the clutch box out of action
just before the ratchet wheel shaft has completed a revolution. The cam for raising
the guides I may place upon one of the cam shafts instead of placing it as in the
ordinary Weild machine upon the escapement shaft in the head stock and I form
the said cam so as to keep the guides up while the end of the thread is being
pressed upon the surface of the coil. A wire or guide may be protruded from a
groove in the metal at the side of the coil just before the operation last described
of pressing down the end of the thread is commenced so as to guide the thread
back into the position on the periphery of the coil from which it had been diverted
by the book which seizes it prior to cutting.

page_text: Improvements in Machinery for Winding Colls of Thread for
Use in Sewing Machines or for other Purposes.
I, ALGERNON DEWHURST of the firm of John Dewhurst and Sons of Skipton in
the County of York Cotton Spinners and Sewing Cotton Manufacturers do hereby
declare the nature of my invention for "IMPROVEMENTS IN MACHINERY For
WINDING COILS OF THREAD FOR USE IN SEWING MACHINES OR FOR OTHER
"
PURPOSES 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 machinery or apparatus for making coils of thread
especially such as are wound without bobbins spools or holders and are generally
enclosed in cases from which the thread is drawn. They are suited for use in
Sewing machines of the kind known as Singers Oscillating Shuttle Machine
but the coils made by the apparatus may be used for any other purpose to which
they are adapted. The invention may be of course applied to either hand machines
or to self acting machines, for example those of the Weild" type for winding a
number of coils at the same time, I will describe the invention as applied to a
hand machine from which its application to the larger kind or self acting machines
will also be understood.
"
The motion of the revolving parts of the machine may be obtained in the
ordinary way by the usual mechanism employed in winding thread on bobbins but
the front spindle is reduced or formed of a size and shape to suit the hole in the
centre of the coil to be wound. A loose collar or tube is arranged so that it can
revolve with and be slidden by a lever or otherwise longitudinally upon the front
spindle at the reduced end, the end of the said loose collar or tube forming one of
a pair of cheek pieces between which the coil is wound and by which the flat or
other shape of the sides of the coil is obtained, the other of the said cheek pieces
being carried by the back spindle arranged in line with the front spindle and
driven at the same speed. The last named cheek piece is pressed forward to its
normal position by a spring but is connected with the same device that gives
longitudinal movement to the first named cheek piece by a lever and thrust piece
or pieces so arranged that when the first named cheek piece is moved longitudinally
the other cheek piece moves with it at the same rate so as to maintain the coil
between them whilst it is pushed from off the reduced end of the spindle upon which
it was formed but when this has been done an accelerated movement is given to
one of the cheek pieces so as to move the one away from the other that the coil
may drop from between the cheeks into a spout or receptacle. One or the other
of the cheek pieces carries hooks or has nicks made in it or equivalent retaining
devices to hold the end of the thread and to carry it round the reduced end of the
spindle in commencing winding. A presser is situated between the cheeks and
presses upon and moves outwards with the thread as it is wound but is retained
out of action when the coil is finished and whilst it is being thrust from the
machine. A thread guide for guiding and traversing the thread backwards and
forwards as each layer is wound may also be used. This may be of the ordinary
kind and be operated in the ordinary way.

page_text: I do not limit myself to the moving of the cheeks precisely as described, as
it will be evident that the cheeks may be moved in either direction and that the
reduced end of the spindle may be itself withdrawn from the check instead of the
cheek being moved over it provided that the relative movements of the parts be
obtained for the purpose hereinbefore described, for example only one of the cheeks
may be made moveable and the other stationary so that the reduced end of the
spindle is first withdrawn from the wound coil and then the moveable cheek is
moved away from the other cheek to liberate the coil. When the Invention is
applied to a self-acting machine the arrangement will be substantially the same as
that hereinbefore described. In this case I may place any number of pairs of the
spindles in suitable bearings upon the table of the machine both the front and the
back spindles being rotated from the driving shaft of the machine: To give a
sufficiently short traverse of the guide rod for making the narrow coils of thread.
I may make the shaper plate wider than the coil and I may place a lever at the
end of the guide rod to diminish the traverse of the rocker shaft, the guide being
so adjusted as to move backwards and forwards without getting down into the
coil nick. A guide with only one groove having a pin across it may be used in
place of the usual guide with a number of grooves. In Weild's machine upon the
back rod for sliding the long front spindles, I may fix an inclined plane to pull
the presser away from the coil before it is forced off the spindle. To the front rod
for sliding the short back spindles I may attach a link or links for the purpose of
operating the parts for allowing the coil or coils to drop out. I prefer the arrange-
ment just described but if desired the inclined plane may be placed upon the
front rod and the back rod be used for operating the parts for releasing the
finished coils.
To slide both the back and the front rods may apply new cams in the same
position as those in Weild's machine for working these rods but so formed as to
cause the presser to move out of the way before the rod for operating the parts for
releasing the finished coils begins to push the coil off the spindle and to keep the
presser out of the way until the machine is again ready for winding.
To catch hold of the starting end of the thread and to carry it round with the
spindle I may place one or more clips or springs or make one or more narrow nicks
on the surface of the collar nearest to the knife and on this collar and nearer to
the part where the coil is wound I may make a projecting ring with one or more
rounded nicks in it and I may make a groove in the surface of the collar and
encircling it between the clips holding the end of the thread and the projecting
ring. Into this groove I may force a knife to cut off the starting end of the thread
or I may force into this groove a hook to pull the starting end of thread away
from the clip so as to leave the coil free to drop down the trough when the coil is
released. To force the knife or the hook into the groove I may fix an inclined
plane to the rod which in Weild's machine moves the knife for cutting off the
starting end of thread.
It is desirable that the coil of thread before being released from the machine
should have a few rotations given to it against the presser after the end of the
thread is cut so as to cause the said end to lie down well in its place.-To effect
this I make in the disc which is at the back of Weild's machine on the ratchet
wheel shaft an extra notch at the diametrically opposite side of the disc to that
of the usual notch and I attach an extra click or pawl (or its equivalent) upon an
extra arm turning upon the ratchet wheel shaft and operated by an extra con-
necting rod moved by the cam shaft. This extra pawl or the like when the cam
shaft has made a portion of its revolution and the knife has been made to act,
moves the ratchet wheel shaft and by that means liberates the mechanism for
putting the winding shaft again in rotation so that the coil is rotated against the
presser in order to make the loose end of the thread lie flat. In order to prevent
the delay which would occur if the ratchet wheel had to be operated tooth by
tooth (as in winding) before the belt would be thrown off it may after a few
revolutions of the winding spindles be again removed from off the winding

page_text: mechanism. To effect this, I throw into action immediately before the belt is
thrown on to the winding mechanism, gear which, when the spindles are revolving,
quickly rotates the ratchet wheel shaft to the position for again throwing the belt
on to the pulley for turning the cam shaft so as to cause it to complete the revolution
it had commenced, and I provide on the cam shaft in the head stock a cam for
holding out of action during the ordinary winding operation of the spindle a clutch
box which forms part of this gear and I further provide on the ratchet wheel shaft
a cam for throwing the clutch box out of action when the ratchet wheel shaft has
turned round to the point at which tho escape plate is liberated for the purpose of
throwing the belt off the winding mechanism on to the pulley for turning the cam
shaft.
The form of the cam for raising the guide is such as to keep the guide up while
the end of the thread is being pressed upon the surface of the coil. A wire or
guide may be inserted in a groove formed in the periphery of the cheek piece
carrying the spring clips just before the operation last described of pressing down
the end of the thread is commenced, to draw the thread out of the rounded nick as
soon as the spindles commence to rotate and to guide the thread back into the
position, on the periphery of the coil, from which position the thread had been
diverted by the hook which seizes it prior to cutting.
I will now explain with reference to the accompanying drawings arrangements
of mechanism according to my Invention by which its nature will be thoroughly
understood but I do not limit myself to the precise mechanical arrangements
illustrated provided that the machine be fitted to fulfil the functions herein before
stated as being of the nature of the Invention and as hereinafter defined by the
claims.
Figures 1. 2 and 3 of the accompanying drawings represent respectively a front
elevation, a plan and a transverse section of a hand machine constructed according
to my Invention for making one roll coil or cylinder of thread at a time and
figure 4 is a front elevation of a modified construction of machine for a like
purpose Figures and 6 are respectively a front elevation and a transverse
section of a portion of a self acting machine constructed according to my
Invention for forming several coils rolls or cylinders of thread at a time and
figures 7 and 8 are respectively a back elevation and transverse section of the
head stock provided with some of my improvements which will be hereinafter
referred to.
The hand machine represented by Figures 1 2 and 3 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 passing round the wharve or pulley a fast on the
front winding spindle A which is fitted to rotate in bearings b in the frame B of
the machine In axial line with the spindle A is mounted in bearings b³ the back
winding spindle A3 which is driven at the same speed as and from the front
spindle A by means of the gearing C and shaft D. One end of the front spindle A
is reduced in diameter as shewn at a³ 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 the thread is wound between two cheek pieces collars or
heads E E mounted respectively on the adjacent ends of the said spindles These
cheek pieces collars or heads are fitted so as to rotate with their spindles but as
shown in figures 1.2 and 3 they are capable of being slidden longitudinally thereon
The cheek piece E is provided with a hole or passage in its centre through which
hole the reduced portion a³ of the spindle A projects and enters a recess in the
face of the cheek piece E2 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 These cheek pieces collars or sliding heads are maintained in their
normal position on the spindles by a helical spring c arranged on the back
spindle A² between the frame B and the back of the cheek piece E2 which latter is
connected to the cheek piece E by thrust pieces or links d d² and the levers F F2
by means of which the longitudinal sliding movements are imparted to the

page_text: said cheek pieces or collars. G is the thread guide for traversing the thread
backward and forward as each layer of thread is wound This guide is mounted
on the rod or shaft H which is fitted to slide longitudinally in the frame B and
from which rod projects an arm e carrying a friction bowl working in the groove
of a cam I mounted loosely on the shaft D-This cam is rotated from the shaft D
at the requisite speed for imparting the necessary motion to the guide G for
laying the thread in uniform layers by means of the worm and worn wheel y
spur wheels h and the bevel wheels which latter is connected to or formed
on the cam I.
In commencing to form a coil or roll of thread the thread from the thread
supply is laid in the groove of the guide G and the end of the thread is placed in
the nick e² in the collar or cheek pieco E2. The machine is then started in the
ordinary manner by friction gearing worked by a treadle or otherwise whereupon
the spindles A and A will rotate and wind the thread upon the reduced portion a²
of the front spindle A between the faces of the collars or cheek pieces E E³. As the
thread is being wound a presser & situated between the faces of the cheek pieces
collars or heads and acted upon by a spring bears against the coil so as to make
it firm or compact This presser is forced outwards by the coil or roll as it
increases in diameter and when the coil or roll is of the requisite size the machine
may be stopped the coil severed from the thread supply and the end disengaged
from the nick c² after which the machine may be again started so as to allow the
coil to make a few revolutions against the presser to cause the loose end to be
snugly laid upon the said coil The machine is then stopped and the presser k is
withdrawn and retained out of action by the eccentric lever acting upon a pin m
projecting from the stem n of the presser and the finished coil or roll of thread
may then be removed from the spindle by moving the lever F in the direction
of the arrow in figure 1 so as to cause the collar or cheek piece E to slide along
the spindle A the other collar or cheek piece E' being simultaneously moved by
the link or thrust piece against the pressure of the spring c This simultaneous
motion of the collars or cheek pieces E E³ is continued until the coil or roll held
between them is slidden off the spindle a after which by a further notion of the
lever F the thrust piece or lever d² is caused to act upon the collar or check
piece E2 so as to move it further from the collar or cheek piece E and thus release
the coil which will then fall on to the sloping trough or shoot p by which it is
conducted into a suitable receptacle The lever F2 is then released whereupon the
cheek pieces or collars under the action of the spring c will resume their normal
position in readiness for the next operation.
Instead of causing both collars or cheek pieces to slide along their spindles for
the purpose of removing the finished coil from the spindle the coil may be held
stationary between the collars or cheek pieces E E³ and the spindle be withdrawn
from the coil An arrangement of this kind is illustrated in figure 4. E E² being
the two cheek pieces or collars between which the coil is formed on the reduced
portion a of the spindle A. When a coil is complete which is effected in the
manner described with reference to figures 1. 2 and 3 the reduced portion a³ of the
spindle A is withdrawn from the coil by moving the lever F in the direction of
the arrow until a pin q in the spindle A comes in contact with the end r of a slot
in the cheek piece or collar E then by a further movement of the lever F2 the
collar or cheek piece E is caused to slide with the spindle and thus release the coil
from between the collars or cheek pieces E. E².
Upon releasing the lever handle F the collar or cheek piece E will resume its
normal position under the action of the spring c whilst the spindle A will under
the action of the spring c² be returned to its normal position with the reduced
portion a between the two collars or cheek pieces in readiness for winding a
fresh coil. The spur wheel C on the shaft D is in this modification made sufficiently
broad to admit of the pinion C on the spindle A sliding along it without becoming
disengaged therefrom.

page_text: In applying my Invention to self acting machines I may arrange any desired
number of pairs of spindles in one machine and rotate them from one driving shaft
I have however shewn in figures 5 and 6 of my drawings only one pair of spindles
for the purpose of illustrating my Invention as applied to a Weild's Spooling
machine and in order to prevent unnecessary complication I have omitted various
details and parts common to such machines but which are or may be used in
combination with my improvements.
Referring to figures 5 and 6 A A' are respectively the front and the back winding
spindles fitted with sliding collars or cheek pieces E E' as in the hand machine
herein before first described-a² is the reduced portion of the spindle A upon which
the coil or roll of thread is formed, G the thread guide, and k the presser for
compacting the coil or roll as it being formed.
To enable narrow coils to be wound in this machine the shaper plate (not shewn
in my drawings) may be made wider than the coil or roll of thread to be formed
and in order to reduce the traverse of the rocker shaft G to suit the narrow width
of coil the said shaft is provided with an arm G connected by a link G6 to the
upper end of a lever G7 centred at its lower end g to the framing of the machine
the central portion of the said lever being connected by a link G6 to an arm G³
fast on the longitudinally sliding rod G10 upon which the thread guide is mounted-
The lever G7 is slotted to enable the connections of the links G6 and G8 therewith
to be adjusted. It will be seen that the traverse of the sliding rod G10 upon which
the thread guide is mounted will be proportionate to the traverse of the rocker
shaft G according as the connections of the links G GS with the lever G7 are
adjusted nearer to or further from each other and towards or from the centre or
fulcrum g and consequently the traverse of the thread guide will be adjusted
accordingly so as to wind the thread evenly between the cheeks.
In commencing to form a coil or roll of thread, the thread from the supply
bobbin is laid in the groove g³ of the guide G thence in one of the rounded nicks e
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 rotate, the thread is wound in regular layers on
the reduced portion a² of the spindle A the guide G being traversed to and fro
in the ordinary manner by means of a right and left hand screw not shewn in
my drawings-k is a presser wheel which under the action of a spring ³ presses
against the coil of thread as it is being wound for the purpose of making it firm
or compact.
While the coil or roll is being wound, a hook L. is released and is under the
action of a spring m² caused to enter a groove in the cheek piece or collar E and
engage the thread between the rounded nicks c3 and the spring clips et so as to
disengage the end of the thread from the clip beneath which it had been secured-
This hook L is released by the removal of a wedge shaped block m³ carried on the
sliding rod m and acting upon a friction bowl m³ attached to the stem m² of the
hook L, the sliding rod m being operated for the purpose of releasing the hook,
by a suitably shaped cam on the ratchet wheel shaft, and being brought back into
its normal position so as to withdraw the hook by the spring m or its equivalent.
The coil having been completed, the winding mechanism stops in the usual
manner and the cam shafts begin to rotate as is well understood-The thread
guide G is then raised in the usual manner by cam No 1. shewn in the drawing
Figure 9 (which represents a plane projection of the cams shewing the relative
positions of the cams surfaces for effecting the various motions hereinafter described)
so as to present the thread in position for the hooked wire w² mounted on the
rod w³ to engage and carry the thread into the path of the hook M to enable the
said hook to engage the thread between the coil and the thread supply and draw it
between one side of the said hook M aud the spring plate N. and also against the
edge of a stationary cutter O whereby the finished coil is severed from the thread

page_text: supply, and the end of the supply thread is secured between the side of the
hook M and the spring plate N; the wire w being caused in the meantime to
resume its normal position-The motions of the wire us and the hook M are
effected by the cams N° 7. and 3 respectively--The coil having been thus separated
from the thread supply, the instrument may be caused to descend by cain N° 4
into the groove in the circumference of the cheek piece or collar E in readiness
to disengage the end of the thread from the rounded nick e² and to lay it on the
coil when it again rotates as hereinafter described-It is desirable before the
finished coil is released from the machine to impart to it a few revolutions against
the presser so as to cause the severed ends of the thread to lie snugly on the coil
-To effect this I employ the mechanism illustrated by Figures 7 and 8 of my
drawing which represent respectively in back elevation and transverse section
a portion of the head stock of a Weilds Spooling Machine, P being the ratchet
wheel shaft, and Q the cam shaft. In the periphery of the disc R fast on the
shaft P, I provide an additional notch or tooth r, with which an additional pawl
or click s mounted on an additional arm t, fitted to oscillate on the shaft P,
engages.
This additional arm is actuated from the cam shaft Q by means of an additional
connecting rod s³ carried at its lower end upon the stud 83 on the arm 84 upon
which the usual-connecting rod s is mounted.
While the instrument is being brought down into the groove
the thread
guide G. is being raised higher as will be seen by referring to the throw of N° 1
cam Figure 9.
The thread having been got well out of the way of the clips et on the cheek
piece E by this further raising of the guide G and the instrument x being in the
annular groove 2 ready to lay the loose ends of thread upon the coil the revolving
notion of the cam shafts may be arrested-While the cam shafts are rotating the
shaft X remains stationary and when the cam shafts have rotated about 90 degrees
the pawls engages the notch and causes the ratchet wheel shaft P to rotate
about 47 degrees or until the escape plate is liberated which takes place when the
cam shafts have rotated about 150 degrees, the depression T in the cam T mounted
on the shaft Q having been then brought opposite the bowl t' on the clutch lever U
so as to permit of the clutch box U2 U³ being put into gear the projection von the
disc Z being already removed out of the way of the bowl w on the lever U.
Therefore when the cam shafts are rotating from 90° to 150° of their revolution
the pawls engages the notch r and rotates the ratchet wheel shaft and in so
doing withdraws the projection v from under the bowl w thereby allowing the
clutches U, U³, to gear so soon as the depression T in the cam T comes opposite
the bowl The winding parts of the machine are then set in motion for the
purpose of rotating the coil against the presser k-This being effected by the action
of the extra pawl s¹ upon the extra notch r rotating the ratchet wheel shaft P so as
to allow the shaper bar of the machine to shoot back into its starting position
during which motion of the shaper bar the escape plate is liberated and allowed to
make a half revolution-During this half revolution of the escape plate the cam
which is upon the same shaft which carries the escape plate (The escape plate
revolves with this shaft but can slide endways along it) by means of a belt fork
shifts the belt off the pulley for driving the cam shafts on to the pulley for driving
the winding spindles.
These escape motions follow one another so rapidly that the belt is thrown from
the cam pulley to the winding pulley almost instantaneously when the extra
pawl g has moved the ratchet wheel shaft P forward to the necessary point, the
notch being arranged in the plate R so that this point is reached when the cam
shaft has turned 150 degrees or thereabouts-In practice it should be a trifle before
the cain shaft has turned 150 degrees so that the cam shaft will come to a stand at
about 150 degrees.
"
The moment the- belt is thrown on to the winding pulley the coil begins to
rotate against the presser k, the loose ends of thread being plucked out of the

page_text: rounded nicks e3 by the instrument x as the cheek piece E revolves, and being laid
by that instrument upon the surface of the coil ready to be pressed thereonto as the
coil revolves against the presser k.
At the moment when the belt is thrown onto the winding pulley the extra
shaft X begins to rotate receiving its motion from the driving shaft Y either
directly by means of the cord y and the gearing Y' or indirectly through one of
the shafts depending upon the shaft Y for its rotary motion for instance through
the shaft V and a suitable arrangement of wheels, the clutch box U2 Us on this
extra shaft X having been put into gear while the shaft X was stationary as
herein before described-The ratchet wheel shaft P thus begins to turn slowly
round the moment the belt is thrown onto the winding pulley, the ratchet wheel
shaft P receiving its rotary motion through the cord y gearing Y clutch box U' U³
and pair of bevel wheels W. W-While this is going on the cam shafts are of course
stationary and they continue so until the belt is again thrown off the winding
pulley onto the cam pulley in the usual way when the ratchet wheel shaft has
turned round about 313 degrees.
By the rotation of the ratchet wheel shaft P the projection von the cam Z is
brought into contact with the bowl w on the clutch lever U so as to disengage the
sliding part U from the part U³ of the clutch box.
The moment the clutch box is thus disengaged the motion of the ratchet wheel
shaft P is stopped-If however it has not rotated sufficiently far to liberate the
escape plate it will be rotated to the necessary extent by the usual pawl acting
upon the teeth of the ordinary ratchet wheel as the shaper finger traverses back-
wards and forwards across the shaper plate.
To save time it is advisable that the projection v, on the cam Z should be so
situated as to disengage the clutches U2 U3 at the same moment that the escape
plate is liberated-When the ratchet wheel shaft P has been rotated to this extent
that is when the shaper bar has been forced so far forward as to permit the escape
plate to make a half revolution in the usual way the belt is thrown off the winding
pulley on to the cam pulley by means of the cam and belt fork herein before
described thereby stopping the rotation of the coils and again starting the cam
shafts which were arrested after they had turned only about 150 degrees as
already described.
As the cam shafts further rotate beyond the 150 degrees the cam T comes in
contact with the bowl t on the clutch lever U and moves the sliding portion U³ of
the clutch box U2 U³ still further away from the other portion Us and prevents the
clutch box U U³ coming into gear again until the depression T is again brought
opposite the bowl t'. The mechanism herein before described for imparting a few
additional rotations to the winding spindles may be applied to self acting spooling
machines generally for the purpose of regulating the length of thread wound on the
bobbins by traversing the thread guide from the position in which it stopped at
the finishing end of the spool into any desired position for commencing the winding
of the thread on to the next spool to be filled. The position to which the thread
guide is brought to commence the winding may be determined by means of change
wheels in place of the gearing Y hereinbefore described. The cam shafts con-
tinuing slowly to rotate, the following operations take place.
At 190 degrees of their rotation cam N° 4 (Figure 9) commences to raise the
instrument a out of the annular groove z in the cheek piece E.
At 200 degrees cam N° 5 commences to remove the presser k away from the
coil.
At 225 degrees cam N° 6 commences to move the cheek pieces E E' along their
spindles and as it (the cam) moves forward it gradually moves the two cheeks
apart by means of rod d' the link d³ and the thrust pieces d and d and allows the
coil to drop from between the cheek pieces into a trough or other convenient
receptacle.
At 300 degrees cam N° 6 allows the cheek pieces to commence to return into their
normal position ready for another coil to be wound.

page_text: At 330 degrees cam N° 1 causes the thread guide to commence its descent into
its normal position.
At 335 degrees cam N° 5 allows the presser to commence its return motion into
its normal position between the two cheeks.
At 346 degrees cam N° 3 commences to raise the hook M into its normal
position.
While the cam shafts have been rotating from 270 to 360 or thereabouts the
usual pawl actuated from the cam shaft Q by means of the arm 81 and con-
necting rod s has been engaging the notch 8 in the plate R and just as the cam
shafts have completed a revolution and returned to their normal position at
0 degrees the pawl 85 has turned the ratchet wheel shaft P about 47 degrees or so
far round that the shaper bar is caused to shoot back from the top to the bottom of
the inclined plane which actuates it into its normal position and to liberate the
escape plate which will then together with the belt fork cam make a half
revolution and throw the driving strap off the cam pulley on to the winding
pulley thereby stopping the motion of the cam shafts and starting the winding
spindles, the thread guide traversing motion, and the movement of the shaper
finger, across the shaper plate.
When the spindles commence to rotate as described one of the spring clips e* on
the cheek piece E catches hold of the thread between the spring plate N and the
guide G which thread had been brought into position for the purpose by the
descent of the thread guide, and as the cheek piece E revolves the end of the thread
is pulled by the clip e' away from between the spring plate N and the hook M and
is carried round with the spindle A as it revolves. The thread guide being above
the space between the two cheek pieces E E' and the end of the thread being
carried round with the spindle the thread is wound upon the reduced portion a² of
the spindle A between the two cheek pieces the backward and forward motion of the
thread being effected by the right and left hand screws in the usual way, the usual
pawl moving the ratchet wheel forward tooth by tooth and with it the ratchet
wheel shaft P, one tooth for each backward and forward movement, that is, for
every two layers of thread upon the spindle.
As the ratchet wheel shaft slowly rotates, the usual cam mounted thereon
actuates the rod m' which permits the hook L to rise into the groove l' in the
cheek piece E so as to pluck the end of the thread away from the hold of the
clip e us herein before described.
As the ratchet wheel continues its rotation the above mentioned cam allows the
rod m under the action of a spring m (or its equivalent) to withdraw the hook L
from the groove 12. The number of teeth in the ratchet wheel corresponding with
the number of double layers to be wound upon the spindle a² and the position of
the teeth on the ratchet wheel being arranged so that as the pawl is engaging the
last tooth the ratchet wheel shaft P is rotated so far round that the shaper bar
acting upon the escape bar or lever liberates the escape plate and allows it to make
a half revolution. The following takes place almost instantaneously with the
completion of the coil.
The pawl engaging the last tooth of the ratchet wheel on the shaft P moves the
shaper bar so far forward that the escape plate is liberated and makes half a revo-
lution and at the same time the belt fork cam makes a half revolution shifting the
belt off the winding pulley on to the cam pulley, the winding then stops and the
cam shafts begin to revolve and at 6 degrees of their rovolution cam Ñ°. 1 begins
to raise the thread guide, at 9 degrees cam N° 3 causes the hook M to commence
to rise.
At 22 degrees cam No 7 begins to move hooked wire 20-At 84 degrees cam
No 3 causes the hook M to commence to descend. At 90 the additional pawl 8¹
engages the notch and commences to rotate the ratchet wheel shaft and continues
to do so to 150 degrees causing the ratchet shaft to turn about 47 degrees. At
93 degrees cam N° 7 commences to move the booked wire w² back to its normal

page_text: position. At 120 degrees cam No 1 causes the thread guide to rise higher At
125 degrees cain N° 4 causes the instrument x to commence to. descend into the
groove and as the cam shafts continue to revolve, the various operations herein-
before described are repeated.
The degrees in the rotation of the cam shafts at which the various motions
hereinbefore described are effected are only given as examples, it being obvious
that they may be varied so long as the consecutive movements are effected
substantially in the order hereinbefore described.
In using the thread from the coils constructed as hereinbefore described the
thread is drawn out from the centre of the coil and as it is being drawn out
the thread becomes either partially untwisted or receives additional twist according
to the side of the coil from which the thread is drawn. In order to compensate for
this untwisting or twisting up of the thread an extra twist may be given to the
thread, or twist may be taken out of it, as the coil is being formed by imparting to
the thread supply bobbin a rotary motion corresponding to or proportionate to the
rotary motion of the winding spindles This may be effected by the arrangement
of mechanism illustrated by Figures 7 and 8 of my drawings in which V are the
thread supply bobbins from which the thread passes to the winding spindles
through the guides V¹.
These thread supply bobbins are mounted on spindles V2 fitted to rotate in
bearings in the frame of the machine and may be held firmly upon the spindles V
by means of thumb screws V1 the spindles V* being each provided with a bevel
wheel V³ in gear with corresponding bevel wheels V fast on a horizontal shaft V5
rotated from the shaft V through the clutch box V10, the shaft V6 receiving its
rotary motion from the shaft V2 by a driving strap V14 passed round the pulleys
V V, the former of which is attached to the pulley V¹s but is loose upon the
shaft V, or this motion may be obtained from any other suitable rotating part of
the machine. The size of the driving wheels and pulleys may be such as that the
motion imparted to the thread supply bobbin spindles shall be equal to the motion
imparted to the winding spindles when coiling the thread, so as to impart to the
thread being formed into a coil, a twist equal to the amount of untwisting which
takes place as the thread is being drawn out from the centre of the said coil, as
herein before described or so as to take out of the thread being formed into a coil,
twist equal to the amount of twisting up which takes place as the throad is being
drawn out from the centre of the said coil, as herein before described, or the size of
the driving wheels and pulleys may be such as that the motion imparted to the
thread supply bobbin spindles, shall bear only a convenient proportion to the motion
imparted to the winding spindles.
In order to stop the rotation of the supply bobbin V during the time that the
coil after it is formed, is being rotated against the presser k for the purpose of
laying the ends of the thread on the coil as herein before described, the shaft V
carrying the bevel wheels V4 is provided with a clutch box V the lever VII for
actuating which, is connected by a rod or chain V12 to the lever U which actuates
the clutch box U2 U3 so that when the bowl is in the recess T2 of the disc T the
clutch V10 is disengaged and the rotation of the thread supply bobbin V stopped.
Similar mechanism may be applied to the hand winding machines herein before
described for the purpose of imparting extra twist to the thread whilst it is being
coiled or for the purpose of taking twist out of the said thread as herein before
described.
The machine as hereinbefore described and illustrated is arranged in the way
I prefer for forming coils of thread having a left handed twist such as the French
Cablé six cord thread but for forming the said coils from thread having a right
handed twist such for example. as the ordinary six cord it is preferred that the
arrangement of the machine be reversed, the head stock being arranged at the left
hand end of the machine, that is to the left of a person facing the front of the
machine, so that the starting end of the coil of thread may project from the centre

page_text: hole in the finished coil on the correct side of the coil for putting back the twist
that would be taken out of the thread whilst the coil is being formed; in which
arrangement the supply bobbins V are caused to rotate in the reverse direction.
