Gentleman do hereby declare the nature of said Invention for "IMPROVEMENTS
IN COP WINDING MACHINES IN PART APPLICABLE TO SPINNING AND DOUBLING
MACHINES" which Invention has been communicated to me from Abroad by
Eugéne Emile Plantrou Junior of Oissel in the Republic of France Cotton Spinner
to be as follows:-
This Invention relates to improvements in machinery for winding Cops part of
which improvements is also applicable to machinery for spinning and doubling and
it consists in constructing and arranging the working parts of such machines as
hereinafter described whereby the drag of the yarn or thread is caused to retard
the rotation of the Cop spindles. and cause the driving cord to slip over the
wharves, the tension of the said cord being regulated by means of a tension regu-
lator also in the employment of a yarn guide bearing directly on the Cop and
enabling double the quantity of yarn to be wound upon a Cop of the same thick-
ness as those usually employed and a novel arrangement of feeding oylinders or
rollers whereby these rollers are enabled to perform the functions of the stop
motions ordinarily employed this arrangement being equally applicable to spinning
and doubling machines.
According to this Invention the yarn from the spools or swift is conducted under
one cylinder or roller and over another roller and motion is imparted to these
cylinders or rollers in such a manner that the yarn is not exposed to any undue
strain or pressure. The two cylinders rotate at a uniform speed and supply the
yarn at the rate of say about 30 metres per minute After passing over
the last cylinder the yarn is carried through a hook or eye forming part of
the traversing guide or presser which has the effect of preventing the thread
from chafing. The thread then makes half a turn on the arm or finger of the
traversing or presser guide before being laid on the Cop. The presser guide being
capable of turning on an axis on a faller bar and adjusted in the required position

about double the usual amount of yarn.
The faller bar is operated by sliding rods connected by a cord or strap to a shaft
to which the requisite alternating rotary motion is imparted by a shaft worked by
means of a cam working a lever and an endless serew operated at each ascent by a
pawl and ratchet wheel which is changed as required according to the number of
the yarn.
The Cop spindles are supported by suitable bearings in bolster and footstep rails
and are provided with wharves having cylindrical barrels Motion is transmitted
to the spindle by a cylinder or tin roller turning at a uniform rate of about 160
revolutions per minute. The cord passes directly from the upper side of this
cylinder to the wharve and returns over a guide pulley and over a tension pulley
or regulator.
The cylinders or rollers supplying the yarn to the cop are driven in such a
manner as to supply the yarn at the rate of about 30 metres per minute and the
cop spindles receiving the yarn from the said rollers describe about 1000 revolu-
tions per minute, the speed of the spindles being regulated according to the
thickness of the cops. The band or cord driving the cop spindles travels at a
speed sufficient to drive the said spindles at the rate of about 2,000 revolutions per
iminute but the actual speed of the spindles is regulated by the rate at which the
yarn is delivered, consequently the rate of speed of the spindle decreases in propor-
tion as the diameter in contact with the presser guide increases and vice versa.
The driving cord travels at a uniform speed and slips over the wharves in propor-
tion as the diameter of the cop increases so that the tension of the yarn is always
uniform and remains unaffected by the increasing diameter of the cop.
This uniform tension of the yarn prevents it from, slipping on the feed rollers
herein before referred to. When the yarn breaks at any point between the feed
rollers and the traversing guide the yarn ceases to hold or bite on the rollers and
the creel or swift having acquired a certain momentum continues to turn and pulls
back the broken end of yarn winding it on the creel or swift in the reverse direc-
tion thus obviating the waste of material and other evils frequently caused. by
breakages. This arrangement is also applicable as a substitute for the stop
motions ordinarily employed in spinning and doubling machinery.
:
The winding machine herein before described is preferably constructed with a
row of spindles on each side, the feed rollers, driving gear and other mechanism
connected therewith being duplicated accordingly.

page_text: I JOHN HENRY JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of this Invention for "IMPROVEMENTS
IN COP WINDING MACHINES IN PART APPLICABLE TO SPINNING AND DOUBLING
MACHINES which Invention has been communicated to me from abroad by Eugène
Emile Plantrou, Junior, of Oissel in the Republic of France, Cotton Spinner, 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 improvements in machinery for winding cops part of
which improvements are also applicable to machinery for spinning and doubling,
and it consists in constructing and arranging the working parts of such machines
as hereinafter described whereby the drag of the yarn or thread is utilized to
retard the rotation of the cop spindle and cause the driving cord to slip over the
wharves the tension of the said cord being regulated by a tension regulator, also
in the employment of a yarn guide bearing directly on the cop and enabling double
the quantity of yarn to be wound upon a cop of the same thickness as those
usually employed, and in a novel arrangement of feeding Cylinders or rollers
whereby these rollers are enabled to perform the functions of the stop motions
ordinarily employed, this arrangement being a'so applicable to spinning and
doubling machines.
And in order that my said Invention may be fully understood I shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several figures on the annexed sheets of drawings, the same letters of reference
indicating corresponding parts in all the figures.
'
Figures 1 and 2 of the accompanying drawings represent respectively a vertical
and a horizontal section of a machine constructed according to this Invention.
The machine illustrated in the drawings is provided with a row of spindles M
on each side the feed rollers, driving gear and other mechanism connected therewith
being duplicated accordingly.
In this machine the yarn or thread from spools B (or their equivalent) is con-
ducted under a feed cylinder or roller C and over a similar cylinder or roller C¹ and
then proceeds to a direct acting traversing guide or presser, R, the parts being so
arranged that the yarn or thread is not exposed to any undue strain or pressure,
which would be liable to deteriorate or weaken it-The two cylinders C. Č¹ rotate
at a uniform speed and supply the thread or yarn at the rate of say about 30 yards
(30 metres) per minute.
After passing over the cylinder C¹ the yarn or thread is maintained at a short
distance from the cop by means of a hook or eye n forming part of the traversing
guide or presser R and serving to prevent the yarn or thread from chafing on the
cop. The thread then makes half a turn on the arm or finger of the presser R
before being laid in the cop on the spindle M. The presser or guide R, being
capable of turning on an axis on a faller bar Tand adjusted in the required position
by a screw, pin or other analogous means, is enabled to form a hard cop containing
about double the usual amount of yarn. The faller bar T is alternately raised and
lowered by sliding rods I working in guides I and connected by a cord or strap I'
to a shaft A to which the requisite alternating rotary motion is imparted by means
of a lover O operated by a cam Y arranged for this purp me and an endless screw

page_text: actuated at each ascent by a pawl and ratchet arrangement V which is changed as
required according to the size of the yarn or thread.
The cop spindles are supported by suitable bearings in bolster and footstep
rails P P and are provided with wharves having cylindrical barrels N over which
the driving cords or tapes are passed. Motion is transmitted to the spindle by a
cylinder or tin roller Z turning at a uniform rate of say about 160 revolutions
per minute. The cords or tapes pass directly from the upper side of this cylinder
to the wharves of the spindles upon which the said cords or tapes make a half
turn and return over a guide pulley B and over a tension pulley or regulator X
(figure 1) which maintains the cord or tape at a uniform tension.
The following description explains the means employed to obtain a differential
winding and regular or constant tension. The feed cylinders or rollers travelling
at the rate of say about two hundred and seventy three revolutions per minute
and being about one inch and three eighths (35 millimetres) in diameter, deliver
the thread or yarn at the rate of about thirty yards (30 metres) per minute. The
spindles receiving the yarn or thread from the said rollers may revolve at an
average speed of about one thousand revolutions per minute, the speed of the said
spindles being regulated according to the thickness of the cops. The cylinder
driving the spindles is about six inches (150 millimetres) in diameter and turns at
the rate of about One hundred and sixty revolutions per minute, so as to tend to
drive the said spindles at the rate of about two thousand revolutions per minute,
but the actual speed of the spindle is regulated by the rate at which the yarn or
thread is delivered, consequently the angular speed of the spindle decreases in
proportion as the diameter in contact with the presser guide increases and vice
versa. The driving cords or tapes travel at a uniform speed but are allowed to
slip to a certain extent upon the wharves so as to admit of the requisite variations
in the speed of the latter corresponding to the variations in the diameter of the
cop; the tension on the yarn or thread is thus maintained uniform and remains
unaffected by the changes in the diameter of the cop.
This uniform tension of the yarn or thread prevents it from slipping on the feed
roller C, which by its rotation also causes the yarn or thread to be maintained on
the cylinder C When the yarn or thread breaks at any point between the feed
roller C'and the traversing guide R it loses its hold or bite on the rollers C C¹, and
the creel or swift at the back (when such device is employed) having acquired a
certain momentum continues to turn and pulls back the broken end of yarn,
winding it on to the creel or swift in the reverse direction, thus obviating the
liability of the broken end becoming entangled in the machinery and preventing
the waste of the materials, and other evils frequently caused by such breakage in
machines of ordinary construction. This arrangement may also be advantageously
substituted for the stop motions commonly employed in spinning and doubling
apparatus.
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
First In cop winding machinery, obtaining an automatic adjustment of the
tension of the yarn or thread by means of driving cords, bands, or tapes, the
tension of which is so adjusted by means of a tension regulator as to allow
the said cords, bands, or tapes, to slip over the wharves of the spindles and thereby
allow the speed of the spindles to vary in accordance with the changes in the
diameter of the cop, substantially as hereinbefore described and illustrated in the
accompanying drawings.
Second-In cop winding machinery, the employment of the direct acting presser
guide R, substantially as hereinbefore described and illustrated in the accompanying
drawings.
Third-The employment in cop winding machinery, or in machinery for
spinning and doubling, of the feed rollers C and C¹ arranged and operating as

page_text: herein before described with reference to the accompanying drawings, whereby it is
rendered possible to dispense with the stop motions ordinarily employed.
Fourth The general combination and arrangement of parts constituting the
improved cop winder hereinbefore described and illustrated in the accompanying
drawings.
