FERDINAND ROSSKOTHEN of Zwittau, Moravia, Austria, Mill Manager, do hereby
declare the nature of this invention to be as follows

When winding yarn or thread into the shape of a "cop or "pirn" the thread-
guide by means of which the yarn or thread is guided while being wound requires to
have two movements in relation to the spindle one an oscillating movement and the
other a movement in a direction parallel or nearly parallel to the axis of the "
or "cop" being wound. The two motions together serve to cause the yarn or thread
to be so distributed as to form a "
cop" or "pirn
The above mentioned movements of the thread-guide in relation to the spindle can
be obtained either by imparting to the thread-guide in addition to its oscillating
movement an additional movement which moves it gradually from the base to the
point of the "cop" or "pirn or by imparting to the thread-guide an oscillating
movement only and causing the spindle to move in the direction of its axis so as to
carry the base of the "cop" or pirn" away from the thread-guide. The motions
first referred to are those generally adopted in forming a <<
cop ог pirn on the
"mule" and the latter motions are those generally employed in winding or forming
а cop or "pirn
in winding machines. Machines for winding yarn or thread
into the form of "
"
cops
or "pirns" have as hitherio constructed been considerably
defective among other defects being that those machines in which both the spindles
and the thread-guides are moved could not be "run" at a high speed because the
spindles on which the ".
"
cops or pirns" are wound can not be firmly supported and
in those machines in which the spindles are not moved in the directions of their axes
the spindles are usually not independent of each other or in those cases in which they
are independent of each other the independence of such spindles 18 only obtained by
the employment of complicated arrangements of apparatus

According to my invention I employ as a thread-guide a two-armed lever which 19
capable of being turned upon a pivot to which I impart a motion which gradually
carries it in the direction of the axis of the spindle. On one end of the two-armed
lever I form or secure a thread-guide The other end of the said two-armed lever is
acted upon by suitable mechanism so that an oscillating motion will be imparted to
the two-armed lever by which each layer of the yarn or thread being wound is
distributed upon the " pirn ог cop." In order that the shocks which might
otherwise arise may be avoided the portion of the two-armed lever which guides the
yarn or thread may be formed the longer. The movement of the pivot on which the
two-armed lever is mounted causes the layers of the yarn or thread to be so arranged
as to form a cop or "pirn."

The pivot before referred to can be caused to move in the direction of the axis of
the spindle by any convenient means According to one arrangement I mount the
said pivot upon a lever so placed that each layer of yarn or thread wound upon the
cop or pirn will cause the said lever to be turned upon its fulcrum and carry
the thread-guide away from the base of the "cop ог "pirn." During the above
described motion of the thread-guide the part at which such thread-guide receives its
motion will continue to oscillate in the same or nearly the same path Instead of the
lever which carries the pivot of the thread-guide being directly acted upon by
the yarn or thread being wound upon the cop or pirn, the said lever may be provided

page_text: with a cup or roller or rollers against which the yarn or thread may act such cup or
roller or rollers being connected to or mounted upon a tube capable of being slidden
upon the lever aforesaid.
In place of employing the yarn or thread wound upon the "cop" or "piru" to
move the lever before mentioned I in some cases employ a cam, incline or screw
to move such lever and in those cases in which it is desired to "doff" at one time all
the "cops"
or pirns" wound simultaneously in a machine the pivots of all the
thread-guides are moved simultaneously but if as I prefer, it be desired that each
spindle shall be independent of the others each pivot must be moved independently

of the others.

In some cases I mount the pivot on which is mounted the thread-guide on a lever
which rests upon a spiral cam which is slowly rotated by means of a ratchet wheel or
by other suitable means. The rotation of the cam will cause the pivot on which the
thread-guide is mounted to be raised. By varying the rate at which the cam is rotated
pirns" of different diameters may be formed. By altering the length of
the lever resting upon the spiral cam a greater or less amount of movement may be
caused to be imparted to the said lever and thus the diameter of the "
'pirns" may be varied without the rate of rotation of the cam being varied.
In those cases in which I cause the yarn or thread wound upon the 'cop or "pirn
to raise a lever, cup or roller or rollers I prefer to employ a
stop motion to stop
the rotation of a spindle when the yarn or thread being wound upon such spindle
becomes broken or absent and thereby prevent injury to the yarn or thread being
caused by the last layer of yarn or thread continuing to rub against the lever, cup or
roller or rollers.

being formed in the "

a catch formed on the lever previously mentioned so as to retain such lever in position
for maintaining the band upon the warve or pulley fast upon the spindle but upon the
yarn or thread breaking or becoming absent the lever first mentioned is allowed
to move and transfer the band to the warve or pulley loose upon the spindle.

Improvements in Machinery or Apparatus for Winding Yarns or
Threads into Cops or Pirns.
I, FERDINAND ROSSKOTHEN, of Zwittau, Moravia, Austria, Mill 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 :-
"
"
"
When winding yarn or thread into the shape of a cop or pirn" the thread-
guide by means of which the yarn or thread is guided while being wound requires to
have two movements in relation to the spindle, one an oscillating movement and the
other a movement in a direction parallel or nearly parallel to the axis of the ' pirn
or "cop" being wound. The two motions together serve to cause the yarn or thread
to be so distributed as to form a "cop" or "pirn."

The above mentioned movements of the thread-guide in relation to the spindle, can be
obtained either by imparting to the thread-guide in addition to its oscillating movement
an additional movement which moves it gradually from the base to the point of the
"cop" or "pirn," or by imparting to the thread-guide an oscillating movement only, and
causing
the spindle to move in the direction of its axis so as to carry the base of the
cop or "pirn" away from the thread-guide. The motions first referred to are
those generally adopted in forming a "cop" or pirn" on the "mule" and the latter
motions are those generally employed in winding or forming a

cop" or pirn'in
winding machines. Machines for winding yarn or thread into the form of "cops" or
"pirns" have as hitherto constructed been considerably defective, among other
defects being that those machines in which both the spindles and the thread-guides
are moved, could not be "run" at a high speed because the spindles on which the
cops" or "pirns" are wound cannot be firmly supported and in those machines in
which the spindles are not moved in the direction of their axes the spindles are usually
not independent of each other or in those cases in which they are independent of each
other the independence of such spindles is only obtained by the employment of
complicated arrangements of apparatus
"
By means of my invention hereinafter described I am enabled to form "cops" or
"pirns" upon spindles which have no movement other than rotation.
According to my invention I employ as a thread-guide a lever which is capable of
being turned upon a pivot, to which I impart a motion which gradually carries it in
the direction of the axis of the spindle. On one end of the lever I form or secure a
thread-guide. The other end of the said lever is acted upon by suitable mechanism so
that an oscillating motion will be imparted to the lever by which each layer of the
yarn or thread being wound is distributed upon the " pirn or cop The movement
of the pivot on which the lever is mounted, causes the layers of the yarn or thread to
be so arranged as to form a "cop" or "pirn"
"

The pivot before referred to can be caused to move in the direction of the axis of
the spindle by any convenient means. According to one arrangement I mount the
said pivot upon a lever so placed that each layer of yarn or thread wound upon the
cop" or "pirn" will cause the said lever to be turned upon its fulcrum, and carry
the thread-guide away from the base of the " cop" or "pirn." During the above
described motion of the thread-guide the part at which such thread-guide receives its
motion will continue to oscillate in the same or nearly the same path. Instead of the
lover which carries the pivot of the thread-guide being directly acted upon by the
yarn or thread being wound upon the "cop" or pirn," the said lever may be
provided with a cup, or roller or rollers, against which the yarn or thread may act
such cup, or roller or rollers being connected to or mounted upon a tube capable
being slidden upon the lever aforesaid

In place of employing the yarn or thread wound upon the "cop or "pir

move such lever, and in those cases in which it is desired to "doff" at one

thread-guides are moved simultaneously, but, if as I prefer, it be desired that each
spindle shall be independent of the others, each pivot must be moved independently of
the others.

which rests upon a spiral cam which is slowly rotated by means of a ratchet-wheel or

the spiral cam, a greater or less amount of movement may be caused to be unparted

In those cases in which I cause the yarn or thread wound upon the "cop" or
"pirn" to raise a lever, cup, or roller or rollers, I prefer to employ a
to stop the rotation of a spindle when the yarn or thread being wound upon such
stop motion
spindle becomes broken or absent, and thereby prevent injury to the yarn or thread
being caused by the last layer of yarn or thread continuing to rub against the lever,
cup, or roller or rollers.
"
"
In those cases in which the lever on which the pivot of the thread-guide is mounted
is moved by means of a spiral cam, screw, or incline, or other suitable means, I prefer
to cause the movement of such spiral cam, screw, or incline or other suitable means to
be stopped when the spindle is stopped, so that "thin" places are prevented from
being formed in the "
cops" or pirns."
68
In an arrangement of "stop motion" which I employ, and which forms a portion
of my invention, I employ a lever mounted upon a pivot and provided with guides,
which when a yarn or thread breaks, or becomes absent, transfer the band by which
the spindle upon which such yarn or thread was being wound is "driven" from a
warve or pulley fast on the spindle, to a warve or pulley loose thereon. The yarn or
thread being wound upon the "
"
cop or "pirn' I pass through an eye formed upon
or secured to one end of a lever turning upon a pivot, the other end of which lever 19
provided with a catch, which so long as yarn or thread is being wound engages with
a catch formed upon the lever previously mentioned, so as to retain such lever in
position for maintaining the band upon the warve or pulley fast upon the spindle, but
upon the
yarn or thread breaking or becoming absent, the lever first mentioned is
allowed to move and transfer the band to the warve or pulley loose upon the
spindle.
I have above described each of the levers or thread-guides as being mounted upon
a lever moved as the "building" of the ". cop" or
yarn or thread wound upon the spindle in conjunction with which such lever or
pirn" proceeds, either by the
thread-guide is used, or by means of a cam or incline or other suitable apparatus, but
I would have it understood that each of such levers or thread-guides may be mounted
and arranged to be moved in any suitable manner so that while guiding the yarn or
thread to be wound upon the spindle such lever or thread-guide may be moved
from the base of the "cop" or "pirn as the "building" of such "cop" or "pirn
away,
proceeds.
"
In the accompanying drawing Fig. 1 is a diagram showing the movements of the
thread-guide which are necessary to be made in relation to the spindle in order that
yarn or thread may be wound upon a spindle in the form of a "cop."
In addition to an oscillating movement such thread-guide must also have a slow.
progressive motion, which progressive motion causes the yarn or thread to be wound
on the spindle in layers.
In Fig. 1, A indicates the part of the thread-guide lever A¹ which guides the
thread. The thread-guide lever A¹ is jointed at A' and A³ to the rods B and C
respectively.
If a short oscillating motion be imparted to the rod C in the direction of the length
of such rod C so that the point A' is moved to A** the part A of the thread-guide

page_text: lever A will be moved to A* and so guide the yarn or thread that a conical layer of
yarn or thread will be coiled upon the spindle 1). If the rod B is gradually moved
in the direction indicated by the arrow E so that the pivot A' shall be moved into the
position indicated by dotted lines A** and without the amount or direction of the
motion of the rod C being altered the part A of the yarn or thread-guide A¹ which
guides the yarn while being wound upon the spindle D will be moved along the path
indicated by the dotted lines A** A***.
"
By the longitudinal movement of the rod B in the direction indicated by the
arrow E the path of the part A is gradually moved from the base to the point of the
"
cop' If instead of an oscillatory motion being imparted to the rod C and gradual
longitudinal motion being imparted to the rod B an oscillating motion be imparted to
the rod B and the rod C be caused to be gradually advanced in the direction opposite
to that indicated by the arrow E the movement of the guide wire A will be similar to
that above described.

The arrangement above described in reference to Fig. 1 is only applicable in those
cases in which a number of "
cops or pirns are being formed or " built
simultaneously, that is, in which the whole number of such "
begun simultaneously and finished simultaneously.
According to another arrangement of my invention each "cop" or "pirn" may be
commenced, wound, and completed independently of the other" "
which are being wound.
แ
cops or pirns
"
C 19 &
One method of carrying this arrangement of my invention into effect is shown in
Fig. 2. The thread-guide a is capable of being oscillated upon a fulcrum'b.
shaft which is caused to oscillate by any convenient means. Secured to the shaft c is
an arm c. Jointed to the arm c¹ is one end of a connecting rod d jointed at its other
end to one and of the thread-guide a. The fulcrum b of the thread-guide a is carried
by a rod e upon which are formed screw threads which take into screw threads formed
in the boss of a wheel which is carried by and free to revolve in a rail and is
prevented by such rail from being moved in the direction of the length of the rod e.
The rotation of the wheel will cause the rode to be moved longitudinally thereby
moving the fulerum of the thread-guide a from the point F to the point F¹. A rod e
and wheel for raising the fulcrumb of the thread-guide a is applied to each thread-
guide a so that each spindle is rendered independent of the others.
Figs. 3 and 4 show an arrangement in which the movement of the fulcrum 6 of the
thread guide a is caused by means of a spiral cam h. The spiral cam h is fast with
the ratchet wheel 7 and is loose upon the shaft k. On the circumference of the spiral
cam h rests a lever / carried by and capable of being turned upon a bar m secured to
any convenient part of the machine
Fast upon the shaft k is an arm k carried by and jointed upon which is a pawl n
the tooth of which passes into the teeth of the ratchet wheel, The shaft k is caused
to oscillate by any suitable means Coiled around the boss of the ratchet wheel, is a
cord o by which is suspended a weight p such weight p tending to turn the ratchet
wheel in the direction indicated by the arrow G. q is a catch which prevents the
ratchet wheel from being turned by the weight pin the direction indicated by the
arrow G.
To the lever is secured a rod r from the upper end of which projects a
stud b which forms the fulcrum upon which the thread-guide a turns The thread-
guide a is jointed at one end a* to one end of a connecting rod d. the lower end of
which is jointed to an arm c¹ fast upon a shaft c which is caused to be oscillated by any
suitable means
The oscillation of the shaft k will by means of the pawl n cause the cam h to be
slowly turned in the direction opposite to that indicated by the arrow G
Such turning
of the cam will cause the lever to he gradually raised thereby gradually raising
the part a** of the thread-guide a which gui les the yarn or thread while being wound
upon the spindle t and thereby cause the yarn to be wound upon the spindle t in the
form of a cop
In the lever, I form a slot through which and through the rod r passes a bolt by
means of which the rod r is secured to the lever l.

page_text: By securing the lower end of the rod in the slot so that such lower end of the
rod is secured nearer to, or further from the bar m the fulcrum b and also the part a**
of the thread-guide a by which the yarn or thread is guided upon the "cop" will
receive a greater or less amount of movement
By means of this simple dovice the diameter of the "cops" may be readily vaned
as when the end a** of the thread-guide a is raised slowly the "cops
" are built of
large "diameter" but it the point a** of the thread-guide a is caused to be raised
more quickly the "cops" are formed of a less diameter.
In Figs. 5 and 6 is shown in elevation and plan an arrangement in which the
fulcrum 6 of the thread-guide a is raised by the yarn or thread as it is wound upon the
spindle u.
น
Upon the lever which has its fulcrum at v is a cone or cup to.
When this cone
or cup w is put on the "cop" which is in the course of being wound the axes of the
spindle u and cone or cup ware in one straight line. In order that this may take
place I mount upon the lever and free to be slidden thereon a tube v² provided with
a stud upon which and free to be turned thereon is a collar w¹ to which the cone or
cup wis secured. The thread-guide lever a 1s carried upon the lever by means of a
fulcrum b Mounted upon and free to slide upon the end a* of the thread-guide
lever a is a tube x provided with a stud ¹ which passes into a hole formed in an arm y¹
fast upon a shaft y to which an oscillating motion is imparted by any convenient means.
The oscillation of the shaft y will by means of the arm y' stud and tube x impart
an oscillating motion to the thread-guide lever a.
In the side of the cone or cup w next to the thread-guide a I form a slot w³ through
which the yarn or thread passes from the thread-guide a to the " cop being wound
upon the spindle u Each layer or yarn or thread which is wound upon the spindle u
by means of the thread-guide a lifts the cone or cup w and along with it the lever v
and the fulcrum b carried thereby
The lever has its fulcrum at o' and when the thread-guide a is midway between the
extremes of its oscillations upon the stud a' the axis of the stud ¹ and the fulcrum v¹
of the lever vare in the same straight line, consequently the path of the part a** of
the thread-guide a by which the yarn or thread is guided upon the " cop "always
-remains opposite the slot w² of the cone or cup w. To facilitate the piecing of the
yarn of thread the cone or cup w lever and thread-guide a can be turned upward
until the lever rests against and is supported by a rail z secured to the framework of
the machine, as shown by the dotted lines H The railz also supports by means of a
bracket 2 the stud v¹ The turning of the parts above mentioned as indicated by the
dotted lines may be accomplished without stopping or interrupting the oscillating
motion of the arm y¹ for, as the tube x is free to be slidden along the thread-guide a
and-can also-turn the stud¹ round, it is free to follow the motion of the arm yl
although the level v, cone or cup w and thread-guide a are turned into the raised
position shown by the dotted lines H.
In some cases I mount the cone or cup w upon the lever as shown in Figs. 7 and 8.
Fig 8 being a plan of that which is shown in elevation in Fig 7. Upon the lever v
a portion only of which is shown I mount so that it is capable of being slidden thereon
a tube to one end of which is jointed the cone or cup w.
I am fully aware that before the date of my application for a patent, in machines or
apparatus for winding yarn or thread into "
"
cops or "pirns" spindles have been
employed which have no movement other than rotation but, in such cases where the
yarn or thread-guides used in conjunction with such spindles were influenced by the
yarn or thread wound upon the spindles, the entire thread-guide which was generally
a bell-crank-lever was moved from one position to another but according to my
invention the apparatus which I employ only turns upon the fulcrum v
When the yarn or thread is employed to move the tulerum upon which the thread-
guide lever a is carried such moving of the fulcrum 6 ceases simultaneously with the
breakage of the yarn or thread being wound, and as long as no more layers of yarn
or thread are wound upon the ", cop" or pirn the cone or cup and with it the
fulcrum of the thread-guide remain stationary. In those arrangements in which the
88
"

page_text: "
fulcrum of the thread-guide is not moved by the yarn or thread wound upon the "
cop
or "pirn" but by special mechanism it is desirable that the progressive motion of the
fulcrum should cease when the thread breaks; for if this is not the case
a gap or
hollow will be formed in the body of the "4
66
cop" or pirn "being wound corresponding
with the time which has elapsed between the breaking and the piecing of the yarn
or thread.
,
In Figs. 3 and 4 previously referred to, is shown a stop motion by means of which
I cause both the revolution of the spindle and the progressive motion of the thread-
guide to be stopped when yarn or thread breaks.
For this purpose I provide the spindle t with two warves 2. 2ª the upper warve 2
being fast upon the spindle t and the lower warve 2ª being loose upon the said
spindle t.
3 is a lever carried by and free to be turned upon a stud 4 secured to the spindle
rail 5 or any other convenient part of the machine
Projecting from the lever 3 are two pegs 6 between which passes the hand 7 by
means of which the spindle t is
" driven Secured to the spindle-rail 5 or other
convenient part of the machine is a stud 8* upon which and free to be turned thereon
is a lever & formed at one end with a curl or eye 8 and at the other end with a tooth 8°
which at times hooks upon a tooth formed upon the lever 3 The levers 3, 8, are shown
in the position which they occupy when yarn or thread is being wound upon the
spindle t The yarn or thread being wound upon the spindlet passes through the eye
or curl 8 and thence over the guide pulley 9 and thence through the guide of the
thread-guide lever a So long
is the tension of the yarn or thread maintains the lever 8
in the position in which it is shown, the band 7 will pass around the warse 2 and drive
the spindlet but, upon the yarn or thread becoming broken or absent, the end 8° of
the lever 8 will be caused by its weight to descend into the position shown by the dotted
lines J and thereby carry the tooth 8° clear of the tooth upon the lever 3 which will
then by its weight be caused to descend into the position in which it is indicated by
the dotted lines M. The descent of the lever 3 will by means of the pegs 6 carry the
band 7 from the warve 2 to the warve 2ª and thus stop the spindle t.
The descent of the lever 3 will cause it to arrive against a projecting part n' formed
on the pawl n and thus raise the pawl n clear of the teeth of the ratchet wheel 1 and
consequently prevent motion from being imparted to the ratchet wheel j.
In some cases I propose to employ the above described apparatus for stopping the
spindle t and ratchet wheel, when the yarn or thread becomes broken or absent, for
also stopping the spindle t and ratchet wheel 3 when the "cop" or "pirn" becomes
full. To accomplish this part of my invention connect any convenient and suitable
part of the "rising motion" with the lever. 8-so that when the part of the " rising
motion "which is connected to the lever 8 has attained the desired height the lever 8
will be turned downward so as to turn the tooth 8 clear of the tooth upon the lever 3
stop "the spindle t and ratchet wheel J.

I have above in most cases described and shown my invention applied to regulate
the building of the "cop" or "pirn upon each individual spindle, but if desired such
apparatus can be employed to govern the "building" of the yarn or thread upon a
number of spindles simultaneously.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. In a machine for winding yarns or threads into "cops" or "pirns," the herein-
before described combination of parts consisting in a thread-guide-lever such as a, an
oscillating arm such as c', or y¹ and a fulcrum such as b gradually moved from one
position to another as the winding of a cop" or pirn" progresses or is to progress,

with a thread-guide-lever such as a to which are imparted two movements firstly, an

page_text: oscillating motion by which the yarn or thread in each "cop" or แ pirn" is caused to
be distributed in layers, and secondly, a progressive motion which causes a progressive
movement of the fulcrum of the said thread-guide-lever, so as to cause the layers of
varn or thread to be arranged so as to form a "cop" or
" pirn" of the desired form
the amount of each of which movements is controlled by the lengths of the levers
employed and capable of being varied by variations being made in the lengths of
such levers.
