Improvements in Spinning and Doubling Cops of Cotton and other
Fibrous Materials, and in Machinery or Apparatus therefor.
We THOMAS SEED of West View Cadley, Mill Manager, and JAMES SEED
of 4 Avenham Terrace Engineer both of Preston in the County of Lancaster, do
hereby declare the nature of this invention to be as follows:-
This invention relates to an improved system of spinning and doubling cotton
and other fibrous materials and winding the same onto bare spindles or tubes in the
form of cops on ring frames, and other spinning and doubling machines to which
the ring and traveller system of spinning is applicable and which are used for
spinning and doubling such fibrous substances.
It is found impracticable to use the ordinary ring and traveller system of
spinning for forming cops on the bare spindle, owing to the great number of
breakages of the yarn or thread which occur whilst forming the nose of the cop
on the small diameter of the spindle.
The object of this invention is to enable cops of yarn or thread to be formed on
the bare spindle or small tube with yarn or thread spun with the ring and traveller
with greater facility than hitherto.
This invention consists principally in using the ring and traveller system of
spinning at the commencement of the formation of the cop, and at and near the
middle and lower parts of the chase, during the formation of the rest of the cop;
and it is also used for putting au additional quantity of yarn or thread on the lower
part of the chase of the cop.
The upper or smaller parts of the chase of the cop are formed by using another
system, which consists in unwinding the additional quantity of yarn or thread from
the lower part of the chase of the cop, and winding it positively (that is without
any rotation of the traveller) on the upper or smaller parts of the chase of the cop.
The first system is used until the cop bottom has attained a suitable size, then the
two systems are used alternately until the cop is completed.
The apparatus used for carrying these two systems into effect forms one complete
machine, which may be called the new spinning frame.
One method of carrying this invention into effect is to use a ring frame to which
suitable apparatus hereinafter described is applied, to perform the following
operations whereby a cop is formed. At the commencement of the formation of
the cop the ordinary ring and traveller system of spinning is used, with suitable
sized rings, and spindles, and a heart wheel or cam giving the requisite traverse of
the ring rail, until the cop has attained a suitable size.
The improved apparatus is now engaged so that it can be brought into action at
the required moment.
A second heart wheel is now used which causes the simultaneous spinning and
winding by the ring and traveller to take place at and near the middle and larger
diameters of the chase of the cop, and to build an additional quantity of yarn or
thread on the larger diameters of the chase of the cop.
The improved apparatus is now brought into action by a piu on the heart wheel
shaft, lifting a lever and allowing a clutch to be thrown into gear; this clutch
receives its motion through suitable gearing from the cylinder shaft and drives a
cam shaft having suitable cams on it.
The speed of the spinning frame now requires reducing quickly.
This is effected by two cams on the cam shaft, viz.: the brake cam, and the
strap fork cam. The brake cam causes a brake to be applied for a short time
through suitable levers; at the same time the strap fork cam acts on the strap

page_text: fork lever, causing the driving strap to be moved from the fast to the loose pulley,
the same motion of the strap fork lever, through suitable connections, causes a
friction clutch on the cylinder shaft, driven at a suitable speed for winding to be
brought into action; thus retarding and then driving the spinning frame at a
suitable winding speed.
The next operation consists in unwinding or stripping from the cop the additional
quantity of yarn or thread which was built on the larger diameter of the chase of
the cop as above stated.
;
Two faller shafts extend the length of the frame supported by suitable
bearings arms are attached to these shafts, and these arms support two faller
wires one on each side, extending the length of the frame, placed beneath the
yarn and above the guide eyes; hooks are fixed above the wire under which the
yarn passes from the rollers to the guide eyes. The faller shafts are connected
and suitably balanced by weights. A cam, which we call the stripping cam, acting
through a system of levers connected to the faller shafts now causes the faller wire
to rise. On the first motion of the faller wire the clutches through which the
drawing rollers are driven, are thrown out of gear and retained out of gear by a
catch. The faller wire rising bears against the yarn or thread, and deflects it into
the form of a long loop, and thereby unwinds or strips the additional quantity of
yaru or thread off the cops by causing the travellers to rotate quicker than the
spindles; the fallers are now disconnected from the lever which has caused them
to be raised. Weights which we call the relieving weights, having been raised
now act for a short time through levers, on the faller wires, causing them to
commence descending; the amount of fall these relieving weights are allowed to
have is gradually lessened until the completion of the cop; this is effected by
allowing the relieving weights to fall on to supports which are gradually raised by
cams on the block shafts. Rigid, flexible or frictional stops may be used to control
the height to which the faller wire ascends by its momentum.
The next operation consists in winding the yarn which has been taken off the cop,
positively on the upper part of the chase of the cop. The lever which raised the
faller wires still continues to rise until it has lifted a catch; a spring is now
allowed to act, and (through suitable levers, slide bars and shafts) moves certain
projections into the course of the travellers, thereby stopping them. The ring
rail being now raised, and caused to traverse by a third heart wheel or cam on the
cam shaft, and the spindles revolving wind the yarn or thread positively on the
upper part of the chase of the cops without spinning the faller wire being drawn
down by the yarn or thread. The winding-on is continued until the yarn or thread
which was drawn off the cops is nearly all wound on; the faller arm now lifts a
catch which liberates the travellers, which immediately commence rotating, the
ring rail having been traversed a sufficient distance from the nose of the cops to
ensure the travellers having a sufficiently large diameter to enable them to start.
An arm on the faller shaft now moves the catch which allows the roller clutches to
be thrown into gear. The lever which first moved the faller wires now drops and
engages with it again, the faller wires being kept at rest by suitable levers and
weights in their first position.
The third heart wheel now comes out of action, and allows the second heart
wheel to actuate the ring rail.
The strap fork cam now allows a weight to operate which causes the driving
strap to be put on the fast pulley; this also allows the winding clutch to be
disengaged.
The cam shaft having made one revolution is now stopped, the clutch having
been thrown out of gear, and is kept stationary by a spring and lever acting on a
pin fixed to the cam shaft.
The simultaneous spinning and winding on with the ring and traveller is now
continued at and near the middle and larger diameters of the chase of the cops,
and then the additional quantity of yarn or. thread is again put on the larger
diameters of the chase of the cops, and the same cycle of operations takes place

page_text: each revolution of the heart wheel, the yarn or thread being built higher up the
spindles each revolution of the heart wheel until the cops are completed.
The ordinary ring travellers may be used, but we find it advantageous to use the
improved ring travellers for which Letters Patent were granted to James Seed
dated 18th August 1887, No. 11275, in conjunction with the improvements herein
described and also to set the spindles and rings in an inclined position.
We also find it advantageous to apply to this new spinning frame the improve-
ments for which Letters Patent were granted to James Seed dated October 17th,
1888 No. 14906. In reference to the apparatus for driving the new spinning frame
at a high and low speed, the low speed is used for a short time at the commence-
ment of the formation of the cops and at and near the smallest part of the chase
of the cops on which the yarn or thread is wound during the operation of
simultaneous spinning and winding by the ring and traveller, the high speel being
used for the larger diameters of the chase of the cops.
Suitable apparatus is applied for effecting the starting and stopping of this new
spinning frame.
Various mechanical modifications may be made in the details of construction_of
the apparatus for effecting the improvements herein described, in order to render
them applicable to the various makes of ring spinning and doubling frames, and
other spinning and doubling machines to which the ring and traveller system is
applicable, and for the various classes of yarns or threads for which it may be
used.
Various modifications may also be made in the operations for effecting these
improvements in all of which the ring and traveller system of spinning, or doubling
is used for the medium and large diameters of the chase, and positive winding
without spinning for the small diameters of the chase of the cop.

Improvements in Spinning and Doubling Cops of Cotton and other
Fibrous Materials, and in Machinery or Apparatus therefor.
We THOMAS SEED of West View Cadley, Mill Manager, and JAMES SEED
of 4 Avenham Terrace Engineer both of Preston in the County of Lancaster, do
hereby declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
This invention relates to an improved system of spinning and doubling cotton
and other fibrous materials and winding the same onto bare spindles or tubes in the
form of cops on ring frames, and other spinuing and doubling machines to which
the ring and traveller system of spinning is applicable and which are used for
spinning and doubling such fibrous substances.
It is found impracticable to use the ordinary ring and traveller system of spinning
for forming cops on the bare spindle, owing to the great number of breakages of
the yarn or thread which occur whilst forming the nose of the cop on the small
diameter of the spindle.
The object of this invention is to enable cops of yarn or thread to be formed on
the bare spindle or small tube with yarn or thread spun with the ring and traveller
with greater facility than hitherto.
This invention consists principally in using the ring and traveller system of
spinning at the commencement of the formation of the cop, and at and near the
middle and lower parts of the chase, during the formation of the rest of the cop;
and it is also used for putting an additional quantity of yarn or thread on the
lower part of the chase of the cop,

page_text: The upper or smaller parts of the chase of the cop are formed by using another
system, which consists in unwinding the additional quantity of yarn or thread from
the lower part of the chase of the cop, and winding it positively (that is without
any rotation of the traveller) on the upper or smaller parts of the chase of the
cop. The first system is used until the cop bottom has attained a suitable size,
then the two systems are used alternately until the cop is completed.
The apparatus used for carrying these two systems into effect forms one complete
machine, which may be called the new spinning frame.
One method of carrying this invention into effect is to use a ring frame to which
suitable apparatus hereinafter described is applied, to perform the following
operations whereby a cop is formed. At the commencement of the formation of
the cop the ordinary ring and traveller system of spinning is used, with suitable
sized rings, and spindles and a heart wbeel or cam giving the requisite traverse of
the ring rail, until the cop has attained a suitable size.
The improved apparatus is now engaged so that it can be brought into action at
the required moment.
A second heart wheel is now used which causes the simultaneous spinning and
winding by the ring and traveller to take place at and near the middle and larger
diameters of the chase of the cop, and to build an additional quantity of yarn or
thread on the larger diameters of the chase of the cop.
The improved apparatus is now brought into action by a pin on the heart wheel
shaft, lifting a lever and allowing a clutch to be thrown into gear; this clutch
receives its motion through suitable gearing from the cylinder shaft and drives a
cam shaft having suitable cams on it.
The speed of the spinning frame now requires reducing quickly.
This is effected by two cams on the cam shaft, viz. the brake cam, and the
strap fork cam. The brake cam causes a brake to be applied for a short time
through suitable levers; at the same time the strap fork cam acts on the strap fork
lever, causing the driving strap to be moved from the fast to the loose pulley, the
same motion of the strap fork lever, through suitable connections, causes a friction
clutch on the cylinder shaft, driven at a suitable speed for winding to be brought
into action; thus retarding and then driving the spinning frame at a suitable
winding speed.
The next operation consists in unwinding or stripping from the cop the additional
quantity of yarn or thread which was built on the larger diameter of the chase of
the cop as above stated.
Two faller shafts extend the length of the frame supported by suitable bearings,
arms are attached to these shafts, and these arms support two faller wires one on
each side, extending the length of the frame, placed beneath the yarn and above
the guide eyes; hooks are fixed above the wire under which the yarn passes from
the rollers to the guide eyes. The faller shafts are connected and suitably balanced
by weights. A cam, which we call the stripping cam, acting through a system of
levers connected to the faller shafts now causes the faller wire to rise. On the first
motion of the faller wire the clutches through which the drawing rollers are driven,
are thrown out of gear and retained out of gear by a catch. The faller wire
rising bears against the yarn or thread, and deflects it into the form of a long loop,
and thereby unwinds or strips the additional quantity of yarn or thread off the
cops by causing the travellers to rotate quicker than the spindles; the fallers are
now disconnected from the lever which has caused them to be raised. Weights
which we call the relieving weights, having been raised now act for a short time
through levers, on the faller wires, causing them to commence descending; the
amount of fall these relieving weights are allowed to have is gradually lessened
until the completion of the cop; this effected by allowing the relieving weights to
fall on to supports which are gradually raised by cams on the block shafts. Rigid,
flexible or frictional stops may be used to control the height to which the faller
wire ascends by its momentum. :
"
The next operation consists in winding the yarn which has been taken off the

page_text: cop, positively on the upper part of the chase of the cop. The lever which raised
the faller wires still continues to rise until it has lifted a catch; a spring is now
allowed to act, and (through suitable levers, slide bars and shafts) moves certain
projections into the course of the travellers, thereby stopping them. The ring rail
being now raised, and caused to traverse by a third heart wheel or cam on the cam
shaft and the spindles revolving wind the yarn or thread positively on the upper
part of the chase of the cops without spinning, the faller wire being drawn down
by the yarn or thread. The winding-on is continued until the yarn or thread
which was drawn off the cops is nearly all wound on; the faller arm now lifts a
catch which liberates the travellers, which immediately commence rotating, the
ring rail having been traversed a sufficient distance from the nose of the cops to
ensure the travellers having a sufficiently large diameter to enable them to start.
An arm on the faller shaft now moves the catch which allows the roller clutches to
be thrown into gear. The lever which first moved the faller wires now drops and
engages with it again; the faller wires being kept at rest by suitable levers and
weights in their first position.
The third heart wheel now comes out of action, and allows the second heart wheel
to actuate the ring rail.
The strap fork cam now allows a weight to operate which causes the driving
strap to be put on the fast pulley this also allows the winding clutch to be
disengaged.
The cam shaft having made one revolution is now stopped, the clutch having
been thrown out of gear, and is kept stationary by a spring and lever acting on a
pin fixed to the cam shaft.
The simultaneous spinning and winding on with the ring and traveller is now
continued at and near the middle and larger diameters of the chase of the cops, and
then the additional quantity of yarn or thread is again put on the larger diameters
of the chase of the cops, and the same cycle of operations takes place each revo-
lution of the heart wheel, the yarn or thread being built higher up the spindles
each revolution of the heart wheel until the cops are completed.
Suitable apparatus is applied for effecting the starting and stopping of this new
spinning frame.

We will now describe the details of the new spinning frame as they are brought
into operation from the commencement of the formation of the cops to the finish.
At the commencement of the formation of the cops the ordinary ring and traveller
system of spinning is used with suitable sized rings, spindles, and a heart or cam a
to give the requisite traverse of the ring rail, continuing in operation until the cops
have attained a suitable size. The improved apparatus is brought into action
after the attendant has made the two following changes; first the bowl a³ is moved
from heart a to heart a¹ by a lever and fork a and is fixed in position by a pin
passing through the lever a and entering a hole in the bearing supporting the
bowl a³ see Figs. 5 and 6; and secondly the lever b, see Figs. 1 and 7, connected
to shaft by a key is slided on the shaft ' by the rod 62 and lever so that the
stud may engage with lever b at the required moment. The heart a' is now used
to actuate the ring rail and is so shaped to cause the simultaneous spinning and
wiuding by the ring and traveller to take place at and near the middle and large
diameters of the chase of the cops, and to build an additional quantity of yarn or
thread on the larger diameters of the chase of the cops.
The improved apparatus is now brought into action by the stud 6 lifting the
lever which through shaft & lifts the lever & and allows the sliding clutch c to be
thrown into gear with ¹ the revolving part of the clutch, by spring c² (see Fig. 3)
which had been previously compressed. The sliding clutch c is connected by a dog
and disc to cam shaft d. The clutch e' receives its motion from the cylinder shaft
by the pinion fast on the cylinder shaft gearing into c', and pinion c* attached
to et driving c which is attached to c¹ and loose on the cam shaft d.
The two parts of the clutch ce¹ being now in gear cause the cam shaft d to
commence to revolve. The speed of the spinning frame now requires reducing
quickly. This is effected by two cams on the cam shaft d (see Figs. 1, 23) viz. :
the brake cam d acting on the lever attached to the shaft d³ pressing the
lever against the fast pulley e on the cylinder shaft for a short time; and the
strap fork came acts through the bowl e' (see also Fig. 4) on the strap fork
lever e causing the driving strap to be moved from the fast pulley to the loose
pulley k; the same motion of the strap fork lever e³ causes the friction clutch e
loose on the cylinder shaft driven at a suitable speed for winding by grooved
pulley attached to it to engage with the cone e formed on the inside of the fast
pulley thus retarding and then driving the spinning frame at a suitable winding
speed. The connections which cause the friction clutch e' to engage with e are
the lever supported on lever e³ at the centre e', the spring es forces the stop e³ on
lever e against lever ; on the bell cranked lever eo is supported at centre el
when the strap is on the fast pulley the catch e" is engaged with the lever e¹³
i

page_text: having its centre at e" and its other end engaging in a groove in the boss of
friction clutch the pressure exerted on the friction clutch is regulated by the
strength of the spring; els is a spring to keep the friction clutch out of action.
The frame being thus retarded and then driven at a suitable speed for winding.
The next operation consists in unwinding or stripping from the cops the
additional quantity of yarn or thread which was built on the larger diameters of
the chase of the cops as above stated.
The stripping cam now comes into action, acting on the lever "it depresses
the end, the end is jointed to the slide bar f; at the upper end off a stud /**
is fixed and on this stud there is the connecting link f and on there is the faller
unlocking catch 7.
g
Two faller shafts 9 and 1 (see Fig. 2, 9) extend the length of the spinning frame
supported by suitable bearings g; arms g³ are attached to these shafts y g¹ and
these arms support two wires g' and gone on each side placed beneath the yarn
and above the guide eyes, hooks are fixed above the wire under which the yarn
passes from the rollers to the guide eyes. The faller shafts are connected by
segments g' and 98 and suitably balanced by levers supporting weights g10, and
winding balance weight levers g" and weights g supported by cord 7 working
over pulley 9 see Fig. 10, and relieving weight lever g" and weights g" supported
by the rod and cord 9 through the levers g and g" and links 918.
18
A number of these levers and weights are placed at intervals on the faller shafts
to suitably balance and weight them.
On the faller shaft g there is fixed the lever g" having stud "fixed to it (see
Figs. 1 and 2) and the connecting link engages with study".
An upward motion is given to lever g" from through link f and stud g".
The first motion of the lever " causes the roller clutches °, 10 to be thrown
out of gear through the end of lever g" acting on an incline at the end of lever h'
(see Fig. 1) which is connected by shaft to lever ³, the two levers h³ h³ are
are connected by swivel dies to the two sliding clutches and 40, these clutches are
now kept out of gear by a catch supported on a bracket h engaging with a lug
on lever A.
The faller wires rising bear against the yarn, or thread and deflect it into the
form of a long loop as shown in Fig. 9 and thereby unwind or strip the additional
quantity of yarn or thread off the cops by causing the travellers to rotate quicker
than the spindles.
11
The fallers are now unlocked or disconnected from the link, during the upward
motion of the cord and spring f having one end fastened to f and the other to
the bracket f' have been stretched; the fallers are disconnected from link f
by the screw f10 supported on bracket f" depressing the catch f' until it is clear of
the stud g, this allows the spring to disconnect the link f, from the stud g";
a little before this the faller stops g (see Fig. 11) come in contact with the friction
stops these stops of which there are several placed along the faller shafts are
used to control the height to which the faller wires ascend by their momentum.
Weights g which we call the relieving weights having been raised by lever g
and g" now act for a short time on the faller shafts causing the faller wires to
commence descending; the amount of fall these relieving weights are allowed to
bave is gradually lessened until the completion of the cops; this is effected by
allowing the weights to fall on to supports 91 and 18, the levers g₁ being gradually
raised by cams g" on the block shafts g".
16
During the operation of stripping the third heart or cam h fixed on the cam
shaft d causes the ring rail to be gradually raised by acting on the builder lever
through the bowl h¹ see Fig. 5.
The next operation consists in winding the yarn or thread which has been taken
off the cops, positively on the upper part of the chase of the cops.
On the slide bar see Figs. 1, 2, 8, 9, the lever i is supported by the stud i¹,
the spring has one end attached to the slide bar f' and the other to a projection

page_text: from lever i and being stretched forces the stop on lever i against the slide bar f',
is a set screw supported by a bracket fixed to the slide bar f. The bracket
attached to the framing supports shaft, fixed on the shaft are the two arms
and to which is attached the bar, the bar 10 is also supported by bracket, shaft
and arms and is connected to by rods ", and lever is supported on a stud fixed
to the framing. On the shaft the lever is fixed, the spring has one end
attached to lever and the other to the framing; fixed to the shaft is the
lever with which the catch i engages supported by stud and bracket 18 fixed to
the framing; the slide bar supported by bearings attached to the ring rail,
two pins are fixed in slide bar 1 placed one on each side of bar ; in the bar i¹
there is an incline cut, a similar slide bar and bearings is placed on the ring rail on
the other side of the frame. The shafts and one on each side of the spinning
frame are supported on suitable bearings * attached to the ring rails, to these
shafts are fixed the projections 3 one or more for each ring. To the projection *
fixed to the shaft see Fig. 23 one end of the spring is attached the other being
attached to the ring rail.
This set of mechanism is brought into action in the following way :-The slide
bar frising forces the incline on the upper end of the lever i against the lever i¹,
as the lever is prevented from moving by the lever ¹ and catch the lever i is
moved side way so that the pressure of the spring is exerted through the lever i
on the lever, by the upward motion of the slide bar f' the set screw * lifts the
catch thereby liberating the lever, the spring being stronger than the
spring forces the bar forward moving the arm from the stop against
the stop the catch see Fig. 9 now drops over a projection on arm and
retains the bar in this last position, this forward motion of the bar moved the
slide bar forward moving the inclined notch in it opposite a pin in the end of
lever and this allows the spring to raise the projections 28 into the course of
the travellers and thereby stop them. The ring rail being now raised and caused
to traverse by a third heart or cam on the cam shaft d, and the spindles
revolving wind the yarn or thread positively on the upper part of the chase of
the cop without spinning, the faller wires g and 9 being drawn down by the
yarn or thread. The winding on is continued until the yarn or thread which was
drawn off the cops is nearly all wound on; the incline 928 attached to the faller
arm see Fig. 9 now depresses a stud attached to the end of the catch 21
lifts this catch and liberates the bar, during this time the slide bar has fallen
sufficiently to take the lever i from contact with lever so that the catch 31
being lifted the spring causes the bar to be moved to its first position, this
motion of the bar causes the slide bar to be drawn back and the incline of which
acting on the pin in lever depresses it thereby moving the projections 126 down to
their first position and so liberating the travellers.
The mechanism for actuating the projections is similar on each side of the
spinning frame, the motion of bar being conveyed through rods, and lever i¹³
to bar To
The travellers being liberated they commence rotating, the ring rail having been
traversed a sufficient distance from the nose of the cops to ensure the travellers
having a sufficiently large diameter to enable them to start.
The tumbler incline supported by the upper part of 2 allows the lever g" to pass
with very little friction, and the lever depressing the catch liberates the
lever and the spring having being previously compressed now throws the
roller clutches and into gear thus putting the rollers in motion.
The adjustable plate fattached to the stripping cam f see Fig. 17 now allows
the lever to drop. The slide bar is partially balanced by the weight f
supported by a cord passing over the pulley f and attached to slide bar.
When the link was disconnected from the stud " it was thrown back with the
stop 20 against the slide bar f and is in this position when the slide bar fis
dropping, just before the finish of, the drop of the slide bar f the tail f" of the

page_text: link comes in contact with the spring f" attached to the bracket this causes
the link to be thrown forward and engage with the stud 9", the slide bar f* now
rests on the adjustable stop ₤18.
The lever see Fig. 11 supported on a faller bearing bracket has weight g"
attached to one end and bowl gi at the other, this bowl bears against a segment 9"
having an incline on it, a little before the finish of the fall of the faller wires the
bowl g acting against the inclined part of the segment "assists the downward
motion of the faller wires, and then keeps them at rest in their first position; also
at the finish of the downward motion of the faller wires, the lever g acting
through g raises the stop 9" from the position shown by dotted lines in Fig. 11 to
that shown by full lines.
Just before the third heart or cam h comes into action the bowl a' pushes the
tumbler a supported by stud a fixed to cam a' from the position shown by
dotted lines to that shown by full lines see Fig. 13 the cam h acting through
bowl and the builder lever now moves the bowl a' away from the cam a' this
allows the tumbler a³ to fall into the position shown by dotted lines.
The operations previously described having taken place the third heart or cam h
now comes out of action and allows the bowl a to come on to the tumbler a³ the
traverse of the ring rail being now continued by the heart or cam a'.
The hollow e8 (see Figs. 19, 3 and 4) in cam e having come opposite bowl e¹ the
weight e supported by levers e" attached to the strap fork lever causing the
driving strap to be moved on to the fast pulley e, after this motion of
the levere the spring e draws the winding friction clutch e out of action.
see Fig. 3 is an incline and stop attached to the sliding part of the cam
shaft clutch, a little before the cam shaft d has made (one revolution the incline
on c' being forced against the lever causes the clutch c to be brought out of gear
and compresses the spring c³; ; see Fig. 1 is a stretched spring attached to lever,
the lever is supported at end by a stud fixed to the framing, the other end
acting against the stud j fixed in brake cam d' through the cam shaft d forces the
stop on c' against the end of the lever 6 thus stopping the cam shaft d after it has
made one complete revolution and keeping it stationary.
The simultaneous spinning and winding on with the ring and traveller is now
continued at and near the middle and larger diameters of the chase of the cops and
then the additional quantity of yarn or thread is again put on the larger diameters
of the chase of the cops, and the same cycle of operations takes place, each
revolution of the hearts or cams a a' the yarn or thread being built higher up the
spindle each revolution of the said hearts or cams until the cops are completed.
The ordinary ring travellers may be used, but we find it advantageous to use the
improved ring travellers for which Letters Patent were granted to James Seed
dated August 18th, 1887 No. 11275 in conjunction with the improvements herein
described and also to set the spindles and rings in an inclined position.
We also find it advantageous to apply to this new spinning frame the
improvements for which Letters Patent were granted to James Seed dated
October 17th, 1888 No. 14906.
In reference to the apparatus for driving the new spinning frame at a high and
low speed during the simultaneous spinning and winding on with the ring and
traveller the lower speed is used for a short time at the commencement of the cops,
and at and near the smallest parts of the chase of the cops on which the yarn or
thread is wound during the operation of simultaneous spinning and winding by the
ring and traveller, the high speed being used for the larger diameters of the chase
of the cops, it may be effected by the following mechanism. is a loose pulley
on the cylinder shaft having grooved pulley attached to it, is a grooved pulley
fixed to the cylinder shaft, is a carrier and stretching pulley supported by the
stud fixed to the bracket, a continuous band is passed suitably round these
three pulleys, the cam m is fixed on the heart shaft as, m' is a lever fixed to the
shaft m supported by bearings m", m* is a lever also fixed to shaft m³, on the upper
part of the lever.m there is the pin m³ and at the top there is the catch m
R

page_text: supported by a stud m7 fixed to the lever m', the catch m³ is supported by a stud
fixed in a bracket fixed to the framing, on this bracket there are two stops m³, m³,
attached to the bell cranked lever e¹ there is the piece el projecting a little past
the edge of the lever e and so that the catch me may engage with it.
The mode of operation of this mechanism is as follows:-On the commencement
of a fresh set of cops the catch me is turned over on to the stop m' and the
lever m' is moved so that the catch m³ engages with pin m³, the catch me engaging
with the projection e¹ moves the strap fork through the strap fork lever and
causes the driving strap to be moved from the loose pulley k to the pulley 1 and the
pulley through the band driving on to pulley causes the spinning frame to be
driven at a low uniform speed. This speed is used for a short time and then the
catch me is turned over on to the stop mo, disengaging the strap fork and allowing
it to move the driving strap on to the fast pulley and driving the spinning frame
at a high speed. The two speeds viz. the high and low spinning speeds are now
used, the cam m governs the time of using the low and actuates the strap fork in
the following manner (see Figs. 1, 20, and 21), the incline m" acts against the
lever m' and through shaft m', lever m' catch me and piece e¹ moves the strap fork
and causes the driving strap to pass from pulley e to pulley 1, the flat part m" keeps
the driving strap on pulley 1, the incline ma allows the strap to pass quickly from
the pulley to a little on to pulley e, the incline m" allowing the strap to continue
gradually its motion on to pulley e*.
When the heart or cam a is actuating the ring rail the slow speed is used when
the bowl a is at and near the part a' see Fig. 12 and when the heart or cam a¹ is
actuating the ring rail the slow speed is used when the bowl a' is at and near the
part a see Fig. 13.
If at any time it is thought advantageous to run the spinning frame at the high-
speed only the catch me is lifted up and kept up by causing the hook m" attached
to lever m' to engage with a pin fixed in the tail piece of catch m³.
The apparatus for effecting the starting and stopping of this new spinning frame
consists of the following parts: see Figs. 1 and 4 the shaft n extending across the
frame supported by the framing, having the handles n', n³, the levers n' n° and the
eccentric or cam n fixed to it; the lever n³ is connected to bell cranked lever e¹⁰ by
the adjustable chain and link n'. Fig. 4 shows the position of the various parts
when the strap is on the loose pulley k. When starting the spinning frame by
turning the handle n' or n' the chain n' allows the weight e to move the strap 3
fork until the bowl e' comes in contact with the hollow in the cam e and is then
over the fast pulley * and also allows the bell cranked lever e¹ to drop on to the
lever . When stopping the spinning frame the strap being on pulley, the
reverse action of the handle causes the chain n to lift the lever and pull.
the strap fork over the loose pulley k and at the same time the eccentric or cam n° 4
forces up the lever d' fixed to the shaft d³ causing the brake d* to be applied; when
the frame is required to be stopped the driving strap being on the pulley / the same
.reverse motion of the handle causes a stud fixed in lever n' to lift the catch m' by
depressing the tail piece of the same thus liberating the strap fork lever and
retaining it opposite the loose pulley k by the chain n. When the spinning frame 4
is being driven by the winding speed friction clutch and it is required to be
stopped the same reverse motion of the handle lifts the bell cranked lever e¹º and
liberates the lever the spring e¹s then drawing the winding speed friction
clutch e out of action and the brake is applied as in the previous cases.
When a set of cops is completed the ring rail is lowered quickly by the ordinary 5
mechanism used for same in ring frames (not shown in drawings) and a few coils of
yarn are wound during spinning on a braid or the upper part of the sleeve of the
spindles. The boards to which the guide eyes and hooks 9 are attached are moved :
sideway to allow the cops to be doffed. The bowl a' is moved from heart or cam a
to heart or cam a, and the lever is withdrawn from the path of the stud 6 5
preparatory to starting a fresh set of cops.
When the spindles and ring rails are set in an inclined position the shaft * and…..

page_text: bar and the bar 10 and supports each require to be set at the same incline corre-
sponding respectively to the incline of the spindles on each side of the spinning
frame, and the levers and catches in connection with this mechanism require to be
Bet so that they will act in the manner as hereinbefore described.
Fig. 25 represents an elevation of the driving arrangements for the new spinning
frame. Fixed on the countershaft n is the pulley n' the pulley n¹ drives the
pulleys e, k, and as required through the driving strap n². The double grooved
pulley et is driven by the triple grooved pulley n³ by a continuous band n working
in the two grooves of pulley the three grooves of pulley n³ and under the
stretching pulley nº. Figs. 26 and 27 show the formation of the cop chase when
the ring rail is actuated by the heart or cam a and the horizontal and diagonal
lines indicate the distribution of the yarn as it is wound on the chase during
simultaneous spinning and winding with the ring and traveller during one
revolution of the heart or cam a. Figs. 28 to 32 represent the distribution of the
yarn on the cop chase for one complete cycle of operations when simultaneous
spinning and winding on with the ring and traveller, and positive winding on
without spinning are used.
In Fig. 28 the lines between o and o³ represent the yarn put on the chase
during simultaneous spinning and winding as the ring rail is traversed from o to o'
Fig. 29 represents the same as the ring rail is traversed from o² to o, Fig. 30 repre-
sents the same as the ring rail is traversed from o to o and from o³ to o and from
o to o³, this yarn put on between o³ and of is the additional quantity of yarn or
thread previously referred to.
In Fig. 31 the part between o and o' represents the appearance after the
additional quantity of yarn or thread is drawn off; the first coils wound on during
positive winding without spinning are represented between 3 and o' the travellers
being locked or stopped as the ring rail is ascending and near o¹, the ring rail being
now at the nose of the cop o', positive winding continued as the ring rail descends
from o' to o see Fig. 32, at o' the travellers are liberated and simultaneous spinning
and winding on with the ring and traveller again comes into operation and the ring
rail continuing its downward traverse from o' to o.

Ps
Fig. 33 is an elevation of a sight speed indicator, at a suitable part of the new
spinning frame a spindle is supported and driven from the cylinder the tube
on this spindle, the loop pl is fixed to the tube p and hoop p³ is loose on tube
two flat steel springs p³ and p are attached by loops to the two hoops p¹ and p³.
When the indicator revolves the centrifugal force due to the weight of the
springs and p' causes them to be deflected and draw the hoop p' down the tube
to certain positions according to the speed of revolution of the indicator, the tube
is graduated by lines to certain uniform speeds, so that by looking at the position
Assumed by hoop the speed of revolution is known.
The purpose of this indicator is to enable the cam (which governs the two speed
mechanism) to be set at the proper position; and to see that the speed of the
spindles is reduced to the winding speed in the required time, and also shows
whether the strap and bands are driving the new spinning frame at the required
speeds.
Fig. 34 shows a side elevation of an indicator y for ascertaining the tension of
the yarn during stripping and positive winding, and its position on the roller beam
which is shown in section. At one end of indicator q there is a hook which
takes the place of one of the hooks 9 and rests on the guide eye board, at the back
of the roller beam the bearing a supports the indicator an arm 73 is fixed to g,
q is a weight which hangs on g and may be moved to any part of it, q is a staple
spanning to prevent the hook q¹ being lifted too bigh; the arm is graduated
and the weight q' being such that when it is in the position shown the indicator is
balanced, and as q is moved to each of the marks nearer the roller beam a known
force applied at q¹ is required to raise the indicators and thus the pull or strain on
the yarn passing under q' may be ascertained either during stripping, or positive
winding on.

page_text: -
One or more of these indicators may be used on the new spinning frame; or two
or more hooks q' may be attached to 9 taking the places of two or more hooks gʻ
and thus an average indication may be obtained of the tension of two or more yarns
or threads. By the use of this indicator the speed of the spindles may be so
adjusted that the tension or strain on the yarn during stripping does not exceed
certain limits; and the balance weights g, winding weights 9" and relieving
weights g may be so adjusted to give the required tension or strain on the yarn,
or thread during positive winding.
Various mechanical modifications may be made in the details of construction_of
the apparatus for effecting the improvements 'herein described in order to render
them applicable to the various makes of ring spinning and doubling frames, and
other spinning and doubling machines to which the ring and traveller system
is applicable, and for the various classes of yarn or thread for which it may
be used..
Various modifications may also be made in the operations for effecting these
improvements in all of which the ring and traveller system of spinning or
doubling is used for the medium and large diameters of the chase, and positive
winding without spinning for the small diameters of the chase of the cop.
Amongst the various modifications for assisting to effect these improvements we
may mention the following:
The hooks g may be attached to the thread board by a flexible connection; or they
may be put on centres, or attached to a shaft or shafts supported by 'bearings and
suitably weighted, stops being placed a little above them.
The faller wires may be supported by springs attached to the faller arms, or
other suitable connection may be introduced between the faller arms and the
faller wires.
Counter faller wires may be used supported by suitable bearings, shafts, and
arms being suitably balanced and weighted and acting on the yarn (preferably
between the hooks g and the rollers) by deflecting it more or less as the speed of
the faller wires is more or less than that required to give a uniform tension of the
yarn during positive winding and so assisting in equalizing the tension of the yarn
during positive winding. Projections fixed to the faller arms depress the counter
faller wires and keep them out of action during simultaneous spinning and winding
by the ring and traveller.
An additional faller wire may be attached to the faller arms, and placed when
the faller wire is down, in a position below the yarn and between the hooks g' and
the rollers, and flanged bowls or pulleys suitably supported may take the place
of the hooks y, thus when these double faller wires rise they form a double loop
with the yarn or thread stripped from each cop.
A variable speed may be given to the spindles during the operation of positive
winding without spinning. One method for effecting this is by altering the shape
of the cam e so that it allows the strap fork to gradually move the driving strap
on to the fast pulley and liberate the winding friction clutch e during the
operation of positive winding without spinning and thus causing the speed of the
spindles to be accelerated.
Modifications may be made reducing the number of parts and employing simpler
mechanisin as for instance the parts ", 12, 18, and 10 and its supports may be
dispensed with (see Fig. 9) the motion of the slide bar 1 being conveyed through
a connecting bar or link to the slide bar on the opposite side of the spinning frame,
this slide bar having a suitable inclined notch to operate the projections as
described, this modification can only be adopted when the spindles are set in an
upright position. Also the parts h, he and the upper part of 2 (see Figs. 1 and 2)
may be dispensed with, this mechanism being replaced by a suitable lever attached
to and an incline and plate attached to the slide bar and placed so that the
upward motion of slide bar f* causes the incline to act against the lever and put
the roller clutches out of action, and the plate keeps them out of action until the
slide bar has dropped, the incline and plate may be made adjustable so that the

page_text: time of stopping the rollers may be altered; or in certain cases the rollers will. not
require to be stopped at all during the stripping and positive winding of the yarn
or thread, and thus we are able to dispense with the set of mechanism or apparatus
for effecting the stopping and starting of the rollers.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The improved method or system of spinning or doubling cotton or other
fibrous materials and winding the yarn or thread so spun or doubled on to bare

the ring and traveller can be practically effected, viz. :-at the commencement of the
formation of the cops, and at and near the middle and lower parts of the chase
during the formation of the rest of the cop; and it is also used for putting an
additional quantity of yarn or thread on the lower part of the chase of the cops,
and at the parts where it is difficult and impracticable to use the simultaneous
spinning and winding by the ring and traveller that is the upper or smaller
diameters of the chase of the cops by using another system which consists in
unwinding or stripping the additional quantity of yarn or thread from the lower

spindles and winding it positively (that is without any rotation of the traveller) on
the upper or smaller parts of the chase of the cops.
