This invention has reference to apparatus employed in winding woollen worsted,
silk, and other yarn or threads from swifts or cops onto bobbins, spools or tubes.
In practice it is found (more especially when the hanks have been dyed) that
the yarn is both sticky and twisted, which prevents it freely leaving the swift
without extra drag and friction, such extra drag frequently. breaking the
said yarn
By the application of our invention it is intended to prevent such breakages by
the employment of mechanism placed between the swift and bobbin which will
yield and give way to the drag of the yarn, and when the drag is sufficient the
tension thereof will stop the rotation of the bobbin.
The apparatus we employ consists of an arrangement of spiral or other forms of
springs or weights provided with rods and bars capable of sliding in suitable
framework. The front ends of ithese bars are provided with an antifriction pulley
over which the thread passes on its way to the bobbin, and the bars are so arranged
that when the yarn is freely leaving the swift it has no effect upon the springs,
but should the yarn be entangled or stick to the swift the tension thereof upon
[Price BdY

page_text: the anti friction pulley will be such as to cause the springs to yield and compensate
for the increased drag which prevents the yarn breaking, if however the drag
continues, the springs will yield sufficiently far as to cause one of the bars to slide
and extend beyond its bracket as to come into contact with one of the projections
placed on the wharle or on a revolving star wheel placed on the wharle which
drives the spindle and so stops its rotation and prevents the yarn breaking.
Instead of placing the antifriction pulley on the end of a sliding bar we place it
on the end of a balanced lever. At the rear end of this balanced lever is a thumb
screw passing through another lever provided with catches on the underside the
two levers being thus connected together by the said screw and act simultaneously
said screw being adjustable and regulates the tension of the pulley against
the yarn.
Underneath these two levers is a weighted bell crank lever one point of which
is capable of reaching the projections on the wharle whilst the other point comes
into contact with the catches on the underside of the second lever herein mentioned.
An adjustable spring is employed in connection with the first mentioned lever so
as to keep the friction pulley at a suitable tension against the passing yarn.
When the said yarn is sticky or twisted and is not freely leaving the hank the
balance lever will yield to the pressure of the yarn and prevent breakages at the
same time the oscillation of the lever loosens the yarn on the swift.
To provide apparatus to stop the rotation of the bobbin when the hank is finished
or if the yarn should break, we hinge a balance lever on the lifting rod of the
machine the front end of which bears upon the yarn so that when the hank is used
up or if the yarn did break the end of the lever will fall upon the second lever
herein mentioned tilting it in such manner as to allow the point of the bell crank
lever to come into contact with the wharle and so stop its rotation.
Instead of stopping the rotation of the wharle which in some cases is objection-
able we stop the rotation of the bobbin spool or tube by an arrangement of lever
acted upon by the sliding bar herein mentioned

This Invention has reference to apparatus employed in winding woollen, worsted,
silk and other yarn or threads from swifts or cops onto bobbins, spools or tubes.
In practice it is found (more especially when the hanks have been dyed) that
the yarn is both felted and twisted, which prevents it freely leaving the swift
without extra drag and friction, such extra drag frequently breaking the said yarn
By the application of our Invention it is intended to prevent such breakages, by
the employment of mechanism placed between the swift and bobbin which will
yield and give way to the draq of the yarn, and when the drag is sufficient the
tension thereof will stop the rotation of the bobbin.
The apparatus we employ consists of an arrangement of spiral or other forms of
springs provided with rods or bars capable of sliding in suitable framework.
This part of our Invention is shewn at Fig. 1 which is section of so much of a
bobbin winding machine as is necessary to illustrate our Improvements. A is the
wharle, B the spindle, C the spool onto which the thread is wound from the swift D,
and E is the ordinary cup all employed in the usual manner. Our Invention
consists in placing between the spool and swift, an antifriction pulley F capable of
yielding to the pressure of the thread as it travels from swift to spool. On
reference to the Drawings it will easily be seen how this is done-It will be
observed that the pulley F revolves upon a pin fastened to the sliding bar G so
that if the yarn is entangled or at all felted, and not freely leaving the swift, the
spring H will allow the rod and pulley to move forward in the direction of the
arrow, and compensate for the increased drag placed on the yarn; if however the
drag continues the spring will yield sufficiently far as to cause the bar to slide
beyond its bracket I as to come into contact with one or other of the projections
a and b placed underneath the wharle A, and stop its rotation, consequently
preventing the yarn breaking. When the yarn is released and freely leaving the
swift, the spring forces the pulley back again into its normal position.
Instead of placing the antifriction pulley on the end of a sliding bar, we place
it on the end of a balanced lever. At the rear end of this balanced lever is a
thumb screw passing through another lever provided with catches on the underside,
the two levers being thus connected together by the said screw, and act simul-
taneously, the said screw being adjustable and regulates the tension of the pulley
against the yarn.
This part of our Invention is shewn on sheet 2 where Fig 2 is sectional
elevation, Fig 3 front elevation, and Fig 4 plan view of the apparatus we employ
for carrying out our Invention. The wharle, spindle and cup are the same as that
already described, but in this case the friction pulley F is hinged on the lower
end of the balance lever J whilst at the other end of the said lever is a thumb
screw M which said thumb screw also passes through another balance lever N
hinged at P and provided with catches c and d for purposes hereinafter explained.
Immediately under the lever N is a weighted bell crank lever R hinged at S one
point e of the said lever being operated by the lever N whilst the other point f

page_text: comes into contact with the projections a and b underneath the wharle. It will be
understood that when the yarn is felted or entangled and not freely leaving the
swift that the unequal drag thereof will cause the lever J to oscilate upon its
fulcrum Z which oscillation materially assists in loosening the yarn on the swift,
but if the drag continued the rear end of the lever would rise to such an extent as
to take with it the other lever N (which are connected together by the adjustable
screw M) whereby the point e of the lever R would be released from the catch dat
the same time the heavy end of the said lever R would bring its point f into
contact with the projection on the wharle and stop its rotation and so prevent the
yarn breaking. In order that the pulley F may bear against the yarn at a suitable
tension (which varies according to the strength of yarn) we connect the lower end
of a spring T, to the framework and have its upper end connected to a lug which
can be adjusted as required on the lever J by the screw U, whereby the apparatus
can be made to act upon the most delicate yarn. To provide apparatus to stop the
rotation of the bobbin when the hank is finished, we employ a lever V placed upon
the usual lifting rod W and balanced by weights X. The front end of the lever V
is provided with g which bears upon the yarn so that when the hank is used up the
ping would drop into the catch on the top of the lever N and tilt it in such
manner as to release the point e and bring into action the other point f and stop
the wharle.
Having thus described our Improvements and the best means we are acquainted
with for carrying the same into effect, we would have it understood that.we do
not confine ourselves to the precise details shewn and described, as they may be
varied without departing froin the peculiar character of the Invention, but what
we do claim is
Firstly. The employment of apparatus substantially as shewn and described in
Fig 1 for preventing the breakage of yarn and allowing compensation for drag.
Secondly. The employment of apparatus substantially as shown in Figs 2, 3 and 4
for preventing the breakage of yarn and allowing compensation for drag.
Thirdly. The employment of the lever V in combination with the levers N and R
for stopping the rotation of the wharle when the thread is absent.
In witness whereof I the said John Liddell for and on behalf of myself and
the said John Swallow Brierly, Sydney Herbert Brierly, Frederick William Hirst
and David Hamer, have hereunto set my hand and seal this tenth day of October,
in the year of our Lord, One thousand, eight hundred and eighty three.
