COMPLETE SPECIFICATION.
Improvements in Yarn Winding Machinery.
I, JOHN FARRAN, of 147, Cornbrook Street, Brooks's Bar, Manchester, in the
County of Lancaster, Machinist, 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 improvements in yarn winding machinery the object
being to provide means whereby yarn can be wound in cop or bobbin form more
compactly so as to contain more yarn than heretofore has been the case and whereby
the cop or bobbin is prevented from breaking in the shuttle and rendered more
suitable for warping or other purposes.
To this end my invention comprises, firstly, improved means for raising and
lowering the thread guide; secondly, improved means for shaping the cop or
bobbin; thirdly, means for automatically interrupting the rotation of the spindle
when the thread breaks and when the cop or bobbin is finished; and, lastly, means
for steadying the spindles in the winding of very large cops or bobbins.
And in order that my invention may be more fully understood I have caused to
be appended hereunto two sheets of drawings marked with letters of reference
indicating like parts in the various figures.
Figs. 1 & 3, Sheet I, are cross sections and Figs. 2 & 4 plans respectively of
the end portion of a winding frame constructed in accordance with my invention.
Figs. 5 & 6, Sheet II, are similar cross sections and Fig. 7 a plan of Fig. 5
showing some modifications.
In carrying out my invention and referring to Figs. 1 & 2, which show my
invention adapted for the winding of small cops or bobbins from hanks, I mount
in suitable bearings on one or both sides of a frame a, a row or
spindles b.
rows of
Rotary motion is imparted to each spindle warve 6 by means of a drum or
pulley c fixed upon the driving shaft c' and a belt or band c passing over the said
drum or pulley c and two guide pulleys and c suitably mounted opposite to the
said spindles. Between the last named guide pulley and each spindle is mounted
in bearings d, d', a rack e adapted to be slowly raised during the building of the cop
or bobbin, by a pinion el in gear therewith, in this instance rotated by means of a
worm wheel gearing into a worm fl fixed upon a cross shaft f³ carrying a worm
wheel actuated by a worm f fixed upon the guide pulley shaft f which latter
is rotated by means of the guide pulley and belt or band c. The upper end of
the rack e earries a lever g under the influence of a spring g and having an
adjustable fulcrum g³, at its outer end a thread guide 93 and at its inner end a small
pulley g. Upon the bracket d' is fixed a spring d' which retains the rack e in gear
with its pinion e¹ and allows of throwing the same out of gear for the purpose of
lowering the rack by hand, when commencing the winding operation or when the
thread breaks as hereinafter will be described. Upon the shaft f' is also fixed a
cam h, adapted to actuate a lever arm to the free end of which is attached a chain
or band h which is passed over the pulley g' on the lever g, over another pulley e²
carried by a bracket e attached to the lower end of the rack e and its other end
secured to a fixed part, say the bracket d³ of the frame. The said cam, lever arm
and chain or band serve to actuate the thread guide lever g and thus traverse the
thread onto the tube or bobbin.

page_text: Referring to Figs. 3 & 4 the same show my invention adapted for winding large
cops or bobbins in which case I may drive the spindle 6 indirectly by the belt or
band as shown and wherein it is necessary to provide means for steadying the
spindles for which purpose I employ a bracket or socket 62 adapted to receive the
upper end of the spindle, which bracket or socket 62 may be readily lifted and swung
on one side when it is desired to doff the cops or bobbins. I also employ a presser i
under the influence of a spring i and hinged to a part projecting from the rack e
so as to rise and fall with the latter and press constantly against the cop or bobbin
during the building of the same. The rack and thread lever mechanism in this case
are the same as that already described in reference to Figs. 1 & 2, with the exception
that a carrier wheel k and pinion k¹ are interposed between the rack pinion el and
worm wheel to obtain the desired speed of the rack.
Figs. 5 & 6 show another method of actuating the rack pinion e and the cam
shaft f. In this instance, the cam shaft is suitably mounted near to the
driving shaft c¹ and rotated by a pinion / fixed on the latter and gearing into a spur
wheel on the cam shaft f, motion being transmitted from the said cam shaft f
to the rack pinion e¹ by means of the piuion * and two or more pairs of carrier
pinions and wheels, in the present instance two pairs 12 & 1, mounted respectively
upon the studs 14 & 15..
In some cases I may furnish or form the aforesaid rack with two sections of
teeth m & n, as shown in Fig. 6, and employ two rack pinions m¹ & n¹ having different
diameters, the small pinion m² being adapted to gear with the rack section m and
the large one n¹ with section n whereby the speed at which the rack rail e rises is
varied so as to allow of winding more thread upon the, cop or bobbin at one place
than the other.
In order to interrupt the rotation of each spindle automatically when the thread
breaks, or the cop or bobbin has been finished, I mount the guide pulley ca, Fig. 5,
upon one end of a lever which is adapted to slide or rock upon a suitable
. support o the other end of which by means of suitable connections is brought
under the control of the thread in such a manner that when the thread breaks the
. said lever is allowed to slide or tilt, slacken the belt or band 2 and thus interrupt
the rotation of the spindle. The said connections may consist of a draw bar o
having its inner end pivoted to the lower end of the rocking lever and its outer
end formed with recesses o2 adapted to engage on a fixed stud o³ and carrying a
tumbler lever o. From the thread to be wound is suspended a wire o vertically
guided and its upper end formed with an eye p through which the said thread
passes and its lower end jointed to the tumbler lever o. In connection with the
latter and a suitable cam, say h on the shaft f, is employed a feeler lever q which
by means of the said cam is caused to rock constantly and pass clear of the
tun: bler lever o when in its normal position, i.e. when the thread is intact. As
soon as the thread breaks the tumbler lever o falls into the path of the feeler
lever q and the latter contacting with the tumbler lever o causes the bar o' to be
pushed inwards and thus actuate the rocking lever c, as shown in dotted lines
whereby the belt or band c, is slackened and the spindle thus stopped.
In order to interrupt the ascent of the rack e at the same time when the rotation
of the spindle is interrupted, a leg of is attached to the rocking lever o³ the free
end of which is suitably guided and adapted to push and retain the rack e out of
gear with the pinion el when the rocking lever c is moved from the position shown
in full lines to that shown in dotted lines.
To prevent the cop, or bobbin being overwound I employ a knife or thread
severing device, in the present instance consisting of a stationary knife blade r
arranged in connection with a blade r which rises with the rack e between which
the thread passes and is severed when the cop or bobbin is full. This cutting or
severing action also causes the stop motions described to come into operation.
The thread severing and automatic stopping arrangement described although
only shown as applied to the frame represented in Figs. 5 & 6, may be in a similar

page_text: or a like manner applied to the construction of frames shown in the other figures
without departing from the nature of my invention in this respect.
When winding pin cops I wind upon the bare spindle or tubes whilst large cops
or bobbins for warping, knitting and other machines I wind upon tubes or bobbins.
The tubes or bobbins I use may have conical or flanged heads.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performned, I declare that what I
claim, is-
"In yarn winding machinery."
1st. The employment of a rack e in connection with each spindle / which rack
is caused to gradually rise during the building of the cop or bobbin and at its
upper end carries a lever g adapted to rock and having a thread guide g³ by means
of which the thread is wound onto the spindle, tube or bobbin, all substantially as
and for the purpose set forth.
2nd. In combination with the means specified in the preceding claim, a lever h¹
actuated by a cam h and having attached one end of a chain or band passing
over a pulley 9' on the thread guide lever g and around another e on the rack e
