Improvements in Machinery or Apparatus for Winding Yarns or
Threads.
We GEORGE HENRY HOLDEN of Carr Street Manchester in the county of
Lancaster Machinist and JOHN ASHWORTH of the same place Manager, do hereby
declare the nature of this invention to be as follows:--
Our invention relates to machinery or apparatus for winding yarns or threads on
to bobbins, spools or tubes and consists in arrangements for imparting rotary motion
to the bobbins, spools or tubes upon which the yarn or thread is to be wound and
also in arrangements by means of which we arrest the motion of the bobbin, spool or
tube upon which the yarn or thread is heing wound when a yarn or thread or yarns
or threads becomes or become broken or absent.
18
According to the first part of our invention we mount each of the bobbins, spools
or tubes upon which yarn or thread is to be wound, upon a spindle the ends of which
are capable of being moved upwards and downwards in slots formed in brackets
secured to a rail extending lengthwise of the machine. The bobbin, tube or spool
before mentioned rests upon the surface of a pulley or drum the axle of which is
supported in the brackets before referred to. Mounted so as to be capable of turning
about the same axis as the pulley or drum above mentioned is an arm or frame upon
the lower end of which we mount a friction pulley" which may at times be placed
in contact with a pulley mounted fast upon a rotating shaft extending lengthwise of
the machine. We transmit rotary motion from the friction pulley to the pulley or
drum upon which the bobbin, spool or tube rests by means of an endless baud or in
any other convenient manner. We pass each of the yarns or threads to be wound
upon the bobbin, spool or tube through an eye of a suitable "detector mechanism"
of any suitable construction which when a yarn or thread breaks or becomes
absent allows a wire to arrive in the path of a revolving or oscillating ratchet, wiper
or cam.
Carried upon a stud secured to the rail before mentioned is the "setting on lever"
upon the lower end of which is a bowl or roller which at times acts upon a spring
secured to the arm or frame in which the friction pulley previously mentioned is
mounted. Projecting from the "setting on lever" is a pin or projection by means of

page_text: which the said lever is at times prevented from moving by the said pin or projection
being engaged with a catch formed upon an arm projecting from the portion of the
detector mechanism which carries the wires.
When winding of yarn or thread is taking place the "setting on levor" is hell by
the catch before mentioned so that the bowl or roller above mentioned will force
forward the arm or fame carrying the friction pulley so that the said friction pulley
will be held in contact with the pulley fast upon the rotating shaft so that rotary
motion will be communicated from the said pulloy by means of the friction pulley
and endless band to the drum or pulley and thus rotary motion is imparted to the
bobbin, spool or tube.
When a yarn or thread breaks or becomes absent one or more of the wires
previously mentioned will be allowed to descend into the path of the revolving or
oscillating ratchet wiper or cam and the catch will be turned and leave the setting on
lever free to be turned upon its fulcrum by a spring so as to move the friction pulley
out of conta t with the pulley from which it receives rotary motion and into contact
with a brake. The turning of the "setting on lever" removes a projection on such
lever clear of one end of a lever the other end of which is formed us a brake and
arriving against the pulley or drum upon which the bobbin, spool or tube rests, serves
along with the brake previously mentioned to arrest the rotation of the hobbin, spool
or tube. When the broken or absent yarn or thread has been "pieced "the "setting
on lever" is turned until it is again held in position by the liberating lever, such
turning of the "setting on lever" will place the friction pulloy in contact with the
pulley fast upon the rotating shaft.
Mounted upon a stul upon the "setting on lever" and capable of being turned
thereon is a small lever caused to turn by means of a weighted portion which small
lever when the "setting on lover" is being placed into position for causing winding
of yarn or thread to take place raisos the arm provided with the catch before men-
tional so that the said catch will be in a position to engage with the pin or projection
upon the "setting on lever."
When an "end" becomes broken or absent the weighted lover upon the "setting
on lever" is carried out of the way of the catch before mentioned, allowing it to fall
freely, thus allowing the detector wires to move out of the way of the revolving or
Oscillating ratchet, wiper or cam.
A further part of our invention consists in arrangements by which we arrest the
rotation of the bobbin, spool or tube when a yarn or thread breaks or becomes
absent.
According to this part of our invention we mount upon a rotating shaft extending
Jengthwise of the machine a series of drums from which the bobbins, spools or tubes
upon which the yarn or thread is to be wound receive rotary motion.
The spindle upon which each bobbin, spool or tube is placed is carried by a frame
or cradle hinged to a bar or rail extending lengthwise of the machine.
Mounted loose upon the shaft before referred to is a frame or lever one end of
which is provided with a handle and upon the other end of which is suspended a
weight. Formed upon the frame or lever above mentioned is a brake which whe
winding of yarn or thread is taking place is clear of the hobbin, spool or tube
upon which the yarn or thread is being wound. Wo pass each yarn or thread
to be wound upon the hobbin, spool or tubo through an eye of a wire carried in a box
capable of being oscillated upon pivots supported by a bracket or brackets carried by
a rail extending longthwise of the machine.
To the said box which may be called the oscillating box we joint one end of a rod
the other and of which rod is jointed to the upper end of a vertical arm jointed to a
rail extending lengthwise of the machine. The above mentioned vertical arm is
provided with a catch which projects over a catch formed upon the frame or lover
upon which is formed the brake and thereby keeps the brake clear of the hobbin,
spool or tube or the yarn or thread wound thereon. When a yarn or thread breaks or
bucomes alisont a wire previously supported by the yarn or thread will fall into the
path of a revolving or oscillating ratchet, wiper or cam which will cause the oscillating

page_text: box to oscillate and by means of the rol withdraw the catch upon the vertical arm
clear of the catch upon the frame or lever upon which is the brake. The brako will
then by means of the previously mentioned weight be raised and will carry the
bobbin, spool or tube clear of the pulley or drum from which it receives rotary
motion.
The ascent of the frame or lover brings the brake against the bobbin, spool or
tube and arrests its rotation. The brake may be applied either to the flange or
flanges of the bobbin, spool or tube or to the yarn or thread wound upon the said
bobbin, spool or tube.
A further ascent of the lever or frame upon which the brake is formed will cause
a projecting part to arrive beneath the frame or cradle carrying the bobbin, spool or
tube so as to raise the said bobbin, spool or tube clear of the brake leaving the
bobbin, spool or tube free to be turned by the attendant when piecing the yarn or
thread.
The fallen wire before referred to is carried clear of the revolving or oscillating
ratchet, wiper or cam by means of a weight formed upon or acting upon the vertical
rod before referred to. After the yarn or thread has been "pieced" the attendant
depresses the frame or lever so as to allow the hobbin, spool or tube to rest upon the
pulley or drum by which it is driven and in order to cause the catch upon the vertical
lever to engage with the pin or projection upon the lever or frame previously men-
tioned we mount upon a stud upon the said lever or frame an arm formed of such
weight that upon its being caused by the descent of the lover or frame to arrive
against a pin, stud or incline upon the vertical lever such lever will be turned so as to
bring the wires into position for being acted upon by the revolving or oscillating
ratclict, wiper or cam when a yarn or thread or yarns or threads breaks or break or
becomes or become absent. When the catch upon the frame or lever before mentioned
has become held by the catch upon the vertical lever the winding of the yarn or thread
upon the bobbin, spool or tube will take place.
A further part of our invention relates to those winding machines for winding
yarn or thread on to bobbins, spools or tubes, in which vertical spindles are employed
and this part of our invention consists in arrangements for imparting rotary motion
to such spindles and for stopping any one of the said spindles when a yarn or thread
or yarns or threads becomes or become broken or absent. We provide each machine
with a rotating shaft extending lengthwise of the machine fast upon which shaft we
mount drums or pulleys.
We connect each spindle by means of a band or cord or other suitable means with
a pulley carried by a rod or frame capable of being slidden in a bracket or brackets
or turned upon a pivots or pivots secured to the machine.
Fast with the pulley previously mentioned is a pulley which at times may by means
of the rod or frane aforesaid be placed in contact with or removed out of contact with
a pulley mounted fast upon a rotating shaft extending lengthwise of the machine.
When the pulley previously mentioned is in contact with the pulley fast upon the
rotating sluft rotary motion will be imparted to the spindle to be driven.
So long as the spindle is to be driven we keep the pulleys previously mentioned in
contact with each other by means of a suitable catch, spring or weight or suitable
catches, springs or weights but when it is desired to stop the spindle the catch, spring
or weight or catches, springs or weights is or are liberated.
In order to stop the spindle when a yarn or thread becomes or absent we employ
"detector mechanism" to act upon and liberate the catch, spring or weight or
catches, springs or weights by means of which the pulleys above mentioned are kept
in contact with each other.
A further part of our invention refers to those machines employed in winding yarn
or thread on to spools or tubes, in which the yarn or thread is guided to and wound
upon each spool or tube by means of a drum formed or provided with an oblique slot
or groove which slot or groove guides the yarn or thread on to the spool or tube
while such yarn or thread is being wound upon the said spool or tube. We provide
each drum formed with an oblique slot or groove with a pulley around which passes

page_text: an endless band or cord which hand or cord also passes around a pulley mounted upon
a spindle carried by an arm or frame jointed to or capable of being slidden in brackets
secured to a rail extending lengthwise of the machine.
Fast with the pulley on the spindle above mentioned is a wheel or pulley which
when rotary motion is to be imparted to the drum provided with an oblique slot or
groove may by means of the arm or frame before referred to be placed in contact
with a pulley fast upon a rotating shaft extending lengthwise of the machine. In
order to impart rotary motion to the drum before mentioned we press the pulley
previously mentioned against the rotating pulley by means of a suitable catch,
spring or weight or suitable catches, springs or weights and when it is desired to
stop the said drum the said catch, spring or weight or catches springs or weights is or
are liberated.
23
to net upon
In order to stop the drum aforesaid when a yarn or thread or yarns or thread
becomes or become broken or absent we employ detector mechanism
and liberate the catch, spring or weight or enteles, springs or weights by means of
which the pulley above mentioned is kept in contact with the rotating pulley abovo
mentioned.

Improvements in Machinery or Apparatus for Winding Yarns or
Threads.
Wo GEORGE HENRY HOLDEN of Carr Street, Manchester in the County of
Lancaster, Machinist and JOHN ASHWORTH of the same place Manager 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:-
Our invention relates to machinery or apparatus for winding yarns or threads on
to bobbins, spools or tubes and consists in arrangements for imparting rotary motion
to the bobbins spools or tubes upon which the yarn or thread is to be wound and
also in arrangements by means of which we arrest the motion of the bobbin, spool or
tube upon which the yarn or thread is being wound when a yarn or thread or yarns
or threads becomes or become broken or absent.
According to the first part of our invention we mount each of the bobbins, spools
or tubes upon which yarn or thread is to be wound upon a spindle the ends of which
are capable of being moved upwards and downwards in slots formed in brackets
secured to a rail extending lengthwise of the machine. The bobbin, tube or spool
before mentioned rests upon the surface of a pulley or drum the axle of which is
supported in the brackets before referred to. Mounted so as to be capable of turning
about the same axis as the pulley or drum above mentioned is an arm or frame upon
the lower end of which we mount a "friction pulley" which may at times be placed
in contact with a pulley mounted fast upon a rotating shaft extending lengthwise
of the machine. We transmit rotary motion from the friction pulley to the pulley
or drum apon which the bobbin, spool or tube rests, by means of an endless band
or in any other convenient manner. We pass each of the yarns or threads to be
"suitable detector
wound upon the bobbin, spool or tube, through an eye of a
mechanism" of any suitable construction which when a yarn or thread breaks or
becomes absent allows a wire to arrive in the path of a revolving or oscillating
ratchet, wiper or cam. Carried upon a stud secured to the rail before mentioned is
the "setting on lever" upon the lower end of which is a bowl or roller which at
times acts upon a spring secured to the arm or frame in which the friction pulley
previously mentioned is mounted. Projecting from the "setting on lever" is a pin
or projection by means of which the said lever is at times prevented from moving
by the said pin or projection being engaged with a catch formed upon an arm
projecting from the portion of the detector mechanism which carries the wires.
When winding of yarn or thread is taking place the "setting on lever" is held
by the catch before mentioned so that the bowl or roller above mentioned will force
forward the arm or frame carrying the friction pulley so that the said friction pulley
will be held in contact with the pulley fast upon the rotating shaft so that rotary
motion will be communicated from the said pulley by means of the friction pulley
and endless band to the drum or pulley and thus rotary motion is imparted to the
bobbin, spool or tube.

page_text: When a yarn or thread breaks or becomes absent one or more of the wires
previously mentioned will be allowed to descend into the path of the revolving or
oscillating ratchet, wiper or cam and the catch will be turned and leave the "setting
on lover free to be turned upon its fulcrum by a spring so as to move the friction
pulley out of contact with the pulley from which it receives rotary motion and into
contact with a brake. The turning of the "setting on lever" removes a projuction
on such lever clear of one ond of a lever the other end of which is formed as a
brake and arriving against the pulley or drum, upon which the bolhin, spool or tube
rests, serves along with the brake previously mentioned to arrest the rotation of the
bobbin, spool or tube. When the brokon or absent yarn or thread has been "pieced'
the "setting on levor" is turned until it is again held in position by the liberating
lever. Such turning of the "setting on lever will place the friction pulley in
contact with the pulley fast upon the rotating shaft. Mounted upon a stud upon the
"setting on lever" and capable of being turned thereon is a small lever caused to
turn by means of a weighted portion which small lever when the "setting on lever"
is being placed into position for causing winding of yarn or thread to take place
raises the arm provided with the catch before mentioned so that the said catel will
be in a position to engage with the pin or projection upon the "setting on lover."
When an "end" becomes broken or absent the weighted lever upon the "setting on
lover" is carried out of the way of the catch before incutionod, allowing it to full
freely thus allowing the detector wires to move out of the way of the revolving or
oscillating ratchet, wiper or cam.
In the accompanying drawings Fig. 1 is an end view partly in section of so much
of a winding frame as is requisite to illustrate this part of our invention and Fig. 2
is a front view of a portion of that which is shown in Fig. 1. The same letters of
reference are applied to corresponding parts in both of the said figures.
According to this first part of our invention we mount each of the bobbins, spools
or tubos a upon which the yarn or thread is to be wound upon a spindle the ends
of which are capable of being moved upward and downward in slots formed in a
bracket e secured to a rail el extending lengthwise of the machine. The yarn or
thread to be wound upon the hobbin, spool or tube a is passed through a guide d'
secured to a traverse ruil d extending lengthwise of the machine. The bobbin, tube
or spool a rests upon the surface of a pulley or drum e the axle e' of which is
supported by and capable of being rotated in boarings formed in the bracket c.
Mounted so as to be capable of turning about the same axis as the pulley or drum e
above mentioned is an arm or frame in the lower part of which we mount a short
shaft supported by and capable of being rotated in bearings formed in jaws f
formed upon the arm or frame f. The bar passes through and is guided by a
forked bracket* secured to the rail c. Upon the short shaft y we mount a friction
pulley which may at times be placed in contact with a pulley or drum ; mounted
fast upon a shaft extending lengthwise of the machine and, receiving roury motion
in any convenient manner.
Fast upon the short shaft g is a pulloy and fast upon the axle e' is a pulloy 7.
Around the pulley & and the pulley / wo pass an endless band or strap m by means
of which rotary motion is transmitted from the pulley k to the pulloy !. 71 is a
spring secured at one end to the arm or frame and at the other end to a rail o
extending lengthwise of the machine. Secured to the rail o is an arm o' provided
with a fixed part of against which the pulley is at times drawn by the spring n.
y is the oscillating box or plate of a "detector mechanism" which box or plate q is
provided with "drop wires" each of which "drop-wires" p is formed with an
eye p' through which one of the yarns or throuds A to be wound upon the bobbin,
spool or tube a is passed. Carried by and capable of being turned upon a stud
secured to the bracket is the "setting on lever" s, to the lower end of which is
securod a studs provided with a bowl or roller which at times acts upon a
spring secured to a projecting part formed on the arm or frame f. Projecting
from the "setting on lovers is a pin or projection which at times engages with a
catch formed upon an arm g' projecting from the oscillating box or plate q.
f

page_text: 8
According to the positions in which the parts are indicated in Figs. 1 and 2 yarn
or thread is being wound upon the hobbin, spool or tubo a. The "setting on lever"
is held by the catch so that the bowl or roller is acting upon the spring t, thus
tending to turn the arm or frame faround the axle el in the direction indicated by
the arrow B and thus cause the friction pulley / to be held in contact with the pulley
or drum so that rotary motion will be imparted to the friction pulley by the
pulley or drumj. Rotary motion will by means of the pulloy, band m, pulley
and shafte be imparted to the pulley or drum e and thus rotary motion will be
imparted to the bobbin, spool or tube a so as to cause yarn or thread to be wound
upon the bobbin, spool or tube a. When a yarn or thread breaks or becomes
absent one or more of the wires p will be allowed to descend into the path of the
ratchet or wiper w which revolves in the direction indicated by the arrow C, and the
oscillating box or plate 9 will be turned in the direction indicated by the arrow D
upon the pivots by which it is supported and thus the catch will be inoved clear of
the pin or projection and leave the "setting on lever" and arm or frame f, free
to be turned by the spring which will draw the arm or framo fin the direction
opposite to that indicated by the arrow B and move the friction pulloy h out of
contact with the pulley or drum j and into contact with the part o³ which will act as
a brake to arrest the rotation of the friction pulley h, pulley or drum e and bobbin
spool or tube a.

We provide a brake z carried by and capable of being turned upon a stud y
projecting from the bracket c. On the brake is formed an arm a' provided with a
surface or inclined part which at times rests upon and is supported by a pin or
projecting part upon the "setting on lever" S. When the setting on lever" s
is turned in the direction indicated by the arrow E the pin or projecting part sª
passing from under the surface or inclined part will allow the arm r¹ and brake a
to turn upon the stud y and cause the brake to act against the surface of the
pulley or drum e so as to arrest its rotation. When the broken or absent yarn or
thread has been "pieced "the "setting on lever"s is turned in a direction opposite
to that indicated by the arrow E. Such turning of the setting on lever & will cause
the bowl or roller to act upon the spring and thereby cause the arm or frame
to be turned in the direction indicated by the arrow B and cause the friction pulley /
to be pressed against the pulley or drum and so cause rotary motion to be imparted
to the friction pulley h, pulley k, pulley pulley or drum e and bobbin, spool or
tube a so that yarn or thread will be wound upon the bobbin, spool or tube a.
The
movement of the "setting on lever" s in the direction opposite to that indicated by
the arrow E will cause the pin or projections to act upon and support the arm 2¹
by passing beneath the surface or inclined part a Projecting from the "seting
on lever s is a stud 2 and capable of being turned thereon is a small lever =
caused to turn in the direction indicated by the arrow F by means of a weighted
portion the turning of the lever z being limited by the pin 2. When the "setting
on lever
s is being moved in order to cause the winding of yarn or thread to take
place that is to say, when the "setting on lever" s is moved in a direction opposite
to that indicated by the arrow E the lever z arriving beneath the arm q' will raise
the arm q and cause the catch r to engage with the pin u and so retain the
setting on lever s in position for causing yarn or thread to be wound upon the
bobbin, spool or tube a. If it be thought desirable to dispense with the brake
such braker may be dispensed with.
"
If it be thought advantageous a weight may be placed upon or suspended from
the arm so as to enable the brake x to more efficiently act upon the pulley or
drum e.
Although in Figs. 1 and 2 of the accompanying drawings, only one pulley or
drum e is shown any number of pulleys or drums e may be employed in each machine
to wind yarn or thread on to an equal number of bobbins, spools or tubes a and in
conjunction with each of such pulleys or drums e is employed an arrangement of
apparatus similar to that above described.
A further part of our invention refers to those machines employed in winding yarṇ

page_text: or thread on to spools or tubes in which the yarn or thread is guided to and wound
upon each spool or tube by means of a drum formed or provided with an oblique slot
or groove which slot or groove guides the yarn or thread on to the spool or tube while
such yarn or thread is being wound upon the said spool or tube. Wo provide each
drum formed with an oblique slot or groove with a pulluy around which passes an
endless band or cord which hand or cord also passes around a pulley mounted upon a
spindle carried by an arin or framio jointed to or capable of being slidden in brackets
socured to a rail extending lengthwise of the machine. Fast with the pulley on the
spindle above mentioned is a wheel or pulley which whon rotury motion is to be
imparted to the drum provided with an oblique slot or groove may by means of the
arm or frame before referred to, be placed in contact with a pulley fast upon a
rotating shaft extending lengthwise of the machine. In order to impart rotary motion
to the drum before mentioned we pross the pulley previously mentioned against the
rotating pulley by means of a suitable catch, spring or weight or suitable catches
springs or weights and when it is desired to stop the said drum the said catch, spring
or weight or catches, springs or weights is or are liberated. In order to stop the
drun aforesaid when a yarn or thread or yarns or threads becomes or become broken
or absent we employ "detector mechanism" to act upon and liberate the catch spring
or weight or catches, springs or weights by means of which the pulley above
mentioned is kept in contact with the rotating pulloy above mentioned.
This part of our invention is illustrated by Figs. 3 and 4 of the accompanying
drawings Fig. 3 being a front elevation and Fig. 4 a side view showing so much of
one of the machines to which this part of our invention reintes as is necessary to
illustrate the construction and application of this part of our invention.
The same letters of reference are applied to corresponding parts in Figs. 3 and 4.
1 is a drum provided with an oblique slot or groove 1 and employed to guide yarn
or thread to and wind yarn or thread upon the spool or tube 2. The drum 1 is
mounted upon an axle 3 supported by and capable of being rotated in a bracket 4
secured to a frame or rail 5 extending lengthwise of the inchine. Fast upon the
axle 8 is a pulley 6 around which passes an endless band or cord 7 which also passe
around a pulley 8 fast upon a spindle or short shaft 9 carried by and capable of being
rotated in jaws 10" formned on one end of an arm 10. The arin 10 is supported by
and capable of being turned upon a boss 11 formed on the bracket. 4. The arm 10
passes through and is guided by a forked bracket 10* secured to the frame or rail 5.
Fast upon the spindle or short shaft 9 is a pulley 12 which at times is placed in
contact with a pulley or drum 18 fast upon a shaft 14 extending lengthwise of the
machine and receiving rotary motion in any convenient manner. 15 is a rail
extending lengthwise of the machine.
To a projection upon the ruil 15 is secured one and of a spring 16 the other end of
which is secured to the arm 10. Secured to the rail 15 is an arm 17 provided with a
part 18 which at times constitutes n brake.
Projecting from the arm 10 is an arm 10³ upon which are formed an inclined
part 10 and a handle 10. The arm 10 is at times passed beneath a projecting
part 19 formed on a convenient part of any suitable "detector mechanism" 20 by
means of which the projecting part 19 will when a yarn or thread becomes broken or
absent be caused to permit by being removed from the arm 10% the spring 16 to
Tumove the pulley 12 out of contact with the pulley or drum 13 and thus "stop" the
pulley 12, spindle or short shaft 9, pulley 8, pulloy 6, axle 3 and drum 1.
When a
yarn or thread becomes broken or absent the "dotector mechanism" 20 romoving the
projecting part 19 from the arm 10 will permit the spring 16 to remove the pulley 12
out of contact with the pulley or drum 13 and the spring 16 by drawing the arm 10
in the direction indicated by the arrow G will causo the pulley 12 to arrive against
the bruke 18 such brake 18 assisting in "stopping" the pulleys 12, 8, 6 and drum 1.
When the arm 10 is turned upon the boss 11 in the direction indicated by the
arrow G the inclined part 10° acting on the projecting part 19 will cause the fallen
wires of the detector mechanism 20 to be moved out of the path of the revolving
Tatchet or wiper 21.

page_text: After the broken or absent yarn or thread has been "pieced "the attendant
depresses the handle 10d so as to turn the arm 10 in a direction opposite to that
indicated by the arrow G and thereby presses the pulley 12 into contact with the
pulley or drum 13 so that rotary motion will be imparted to the drum 1 so that yarn
or thread will be caused to be wound upon the spool or tube 2. We form the arm 10°
flexible so that it will constitute a spring to keep the pulley 12 in contact with the
pulley or drum 13 when such pulley 12 is required to be in contact with the pulley
or drum 18.
Instead of a spring 16 being employed to withdraw the pulley 12 out of contact
with the pulley or drum 13 a weight may be employed for such purpose.
Although we have only shown one arrangement of detector mechanism any other
suitable arrangement of detector mechanism may be employed for allowing the
pulley 12 to be moved away from the pulley or drum 13 when a yarn or thread being
wound upon the spool or tube 2 by the drum becomes broken or absent.
Although in Figs. 3 and 4 of the accompanying drawings we have shown but one
drum 1 as being employed any number of like drums may be employed in each
machine and in connection with each drum employed may be employed an arrange-
ment of apparatus similar to that above described in reference to this part of our
invention.
Having now particularly described and ascertained the nature our said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is -
1. The hereinbefore described arrangements by means of which rotary motion is
caused to be imparted to each of the bobbins, spools or tubos in a machine for winding
yarns or threads and by means of which upon a yarn or thread becoming broken or
absent the bobbin, spool or tube upon which such yarn or thread was being wound is
caused to stop which arrangements consist in a friction pulley such as k mounted in
an arm or frame such as and employed in conjunction with suitable detector
mechanism and a brake or brakes such as o² or o² and a, substantially as hereinbefore
described in reference to and indicated in and by Figs. 1 and 2 of the accompanying
drawings.
2. The hereinbefore described arrangements by means of which rotary motion is
caused to be imparted to each of the drums employed in a machine for winding yarns
or threads on to spools or tubes by means of drums each provided with an oblique
slot or groove and by means of which upon a yarn or thread becoming broken or
absent the drum imparting motion to the spool or tube upon which such yarn or
thread was being wound is caused to stop which arrangements consist in a pulley
such as 12 monnted in an arm such as 10 and employed in conjunction with suitable
detector mechanism and a brake such as 18 substantially as hereinbefore described
in reference to and indicated in and by Figs. 3 and 4 of the accompanying
drawings.
