PROVISIONAL SPECIFICATION.
Improvements in or Connected with Apparatus Employed for
Winding Yarn or Thread.
I JOHN CORRIGAN of Bridgewater Works Rodney Street Oldham Road Manchester
in the County of Lancaster Machinist do hereby declare the nature of this invention
to be as follows :-
"
This invention relates in the first place to that class of winding machines which
form cops, and are known as "pin cop or pirn winding” machines, and is applicable
more especially to those machines wherein the revolution of the spindle is stopped
when an end of yarn breaks by means of a forked lever, which embraces a wharve
at the lower end of the said spindle.
The invention is designed first to enable the wharve which drives the spindle to be
lifted out of contact with the driving mechanism by an improved automatic and
simple arrangement of stop motion, instead of by hand."
For this purpose instead of the forked lever being made of wire or light rod and
evenly balanced as at present I propose to make the tail end of this lever heavier
than usual so that when free it will always have a tendency by its own weight to
lift the wharve which drives the spindle up out of contact with the driving surface.
I make use of the ordinary revolving wiper oscillating box and detector wires now
well known in drum winding machines and I fix a bell crank lever or other suitable
contrivance on a bracket or attached to a rail at a convenient part between the said
oscillating box and the forked lever. One end of this bell cranked lever supports
(when working) the weighted end of the said forked lever, and the other end is
connected to the oscillating box, so that when the yarn breaks, the bell crank lever is
is caused to be tilted, and so allows the forked lever to drop thus lifting the wharve out
of contact with the driving arrangement and thereby stopping its revolution.
A second part of the invention is designed to enable the spindle to revolve more
steadily in its bearings and also to allow of the spindle being readily taken out,
thereby enabling the cop to be more easily doffed.
At a convenient part of the machine on the top rail I fix a rod on which a plate or
bracket slides, this plate is formed at one end with a spring clip which embraces the
knob of the spindle, a slot being cut therein for that purpose.
A bent spring is provided on this bracket or plate which catches onto the top of
the rod when required to be lifted up and holds it up out of the way for the purpose
of doffing or "piecing."
On the lower end of the knob, I fix by a spring or other convenient arrangement
a disc or washer which projects a little beyond the knob, and bears on the bobbin or cop
on the spindle.
Another part of the invention consists of a simple arrangement of mechanism
whereby I am enabled to stop the spindle as soon as the cop has been completed, and
so to regulate this motion as to form a cop of any desired size.
To the plate or bracket which rises with the pirn I attach a rod extending down-
wards; on this rod is an adjustable finger which can be set higher or lower to suit any
length of cop required. By the time the cop is completed this finger comes in
contact with a projection on the oscillating box, the movement of which stops the
rotation of the bobbin in the same way, as when an end of yarn breaks.

page_text: To assist the lifting of the spindle in cases where fine yarn is being wound I
attach a small weight to the spindle (or to the above named sliding plate which
steadies the spindle) by means of a cord or chain passing over a pulley or bowl
mounted on any convenient fixed part of the mechanisin.
The weight will havo a tendency to raise the spindle as the cop is formed, and will
thus relieve the yarn of the greater part of the strain occasioned by the lifting of
the spindle.
When the yarn is to be wound on a swift, instead of attaching the staves to rigid
arms which can approach one another for doffing I mount them upon arms which are
rigid in a plane transverse to the axis, but, which will yield to pressure exerted in a
direction parallel to the said axis and reduce the diameter of the "swift," and I exert
the pressure by preference by a disc (or equivalent device) sliding on the fly shaft
acting upon the staves and actuated by a lever or other suitable device.
In such machines also when winding from cops onto the swift a special rail with
holes for receiving the skewers of the cops is provided on the cop board for ordinary
reeling, each of these holes being so inclined as to allow the yarn to be drawn straight
from the " nose "of the cop through its wire loop on the fixed wire rail before
passing to the guide rail and onto the reel.
22
A pair of rails is also fixed on the cop board, the one provided with a series of
earthenware bushes and known as the "
pot rail
and the other fitted with small
hanging weights for bearing against the top of the skewers and known as the
back lap rail. In and between these two rails last named the cops are placed
when
gigging" that is when it is necessary that the cops should revolve when
giving off their yarn.
In order to mount these three rails at suitable distances apart and in suitable
positions with regard to the reel it is necessary to make the said cop board about
eighteen inches wide and the attendant or "reeler" is obliged to reach over this broad
cop board when pieceing up or otherwise manipulating the yarn on the reel. My
invention is principally designed to obviate this difficulty by so making and arranging
the rails that the cop board may be made much narrower than before.
For this purpose I combine the pot rail and the skewer rail in one, that is to say,
I provide a single rail with a series of inclined holes, and another series of pot lined
horizontal holes formed therein. Thus the distance hitherto necessary between the
skewer rail and the "pot rail" is dispensed with.
The wire rail is fixed beneath the reel and consequently the attendant can stand
much nearer to the latter.
In order to allow the attendant to find the skewer holes readily when mounting
the cops in the skewer rail I form or fix a guiding ledge thereon preferably close
below the said holes or a groove running across them, and this ledge or groove may
be applied with advantage to the ordinary skewer rails now in use in the "
of winding machinery.
cop board
In frames wherein the yarn or thread is to be passed through a flame or gassed,
instead of mounting the cradle above the winding drum (as is usual in such
apparatus) so that the bobbin rises as the yarn is wound on, I mount it in front of
the drum, and thus I am enabled to get a greater range of diameter of the yarn
wound on the bobbin.
In order to maintain the bobbin in contact with the drum 1 attach a weight to
the "cradle" by means of a chain or cord passing over a rod or pulley, suitably
situated, or otherwise apply a weight to the said cradle.
The cradle is provided with an independent handle as usual and this handle is
retained when the bobbin is withdrawn by means of a latch lever pivotted to the
frame, the inner end of which lever is slotted, and in the slot works a finger from
the pivotted gas jet. The outer end of this latch lever rests on the handle or a
projection therefrom and is so weighted that when released to replace the bobbin
on the driving drum, this outer end will drop, raise the slot at the other end and
put the gas flame into its working position.
In order to prevent this latch lever from dropping too soon, and putting the gas

page_text: flame into position beneath the yarn before the winding has commenced and thus
burning the same (or too late, and thus forming an unfinished length of yarn) I make
this latch lever of such a form that as the said handle approaches the driving drum,
the said lever rests on the projection from the handle for some distance and is then
provided with an incline which will allow it to drop as soon as the projection
reaches the said incline; and thus the attendant can gradually cause the handle to
approach the driving drum and immediately the bobbin touches the latter, he leaves
the handle altogether, and thus the latch lever will drop and move the gas flamo
simultaneously with the commencement of winding.

COMPLETE SPECIFICATION.
Improvements in or Connected with Apparatus Employed for
Winding Yarn or Thread.
I JOHN CORRIGAN of Bridgewater Works, Rodney Street Oldham Road, 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 in the first place to that class of winding machines which
form cops and are known as pin cop" or pirn winding machines, and is
applicable more especially to those machines wherein the revolution of the spindle is
stopped when an end of yarn breaks by means of a forked lever, which embraces the
boss of a wharve or a bevil wheel at the lower end of the said spindle.
The invention is designed first to enable the boss of the wharvo or bevil wheel
which drives the spindle to be lifted out of contact with such wharve or bevil wheel
by an improved automatic and simple arrangement of stop motion instead of by
hand.

Fig. 1. on the annexed drawings is a vertical transverse section showing so much
of a
6: pin cop
or pirn winding frame as is necessary to illustrate my invention.
Figs. 2. 3 and 4 aro detached views drawn to a larger scale of parts hereinafter
referred to.
The drawing illustrates a frame wherein the spindles a are driven by skew bevel
gearing from the main shaft c.
Instead of the forked lever being of wire or light rod and evenly balanced as at
present, I propose to make this lever bell cranked as shown on Fig. 1. the end d
thereof being heavier than usual so that when free it will always have a tendency by
its own weight to lift the bosse which drives the spindle up out of contact with the
driving surface of the bevel pinion ¹.
I make use of a revolving wiper/oscillating box g and of ordinary detector wire g*
such as are now well known in drum winding machines and I fix the bell crank
lever d, d' or other suitable contrivance on a bracket attached to a rail i.
The end of this bell cranked lever is forked as before stated (see sectional plan
Fig. 3) and the end d rests against a projection on the oscillating box y so that
when the yarn breaks, the bell crank lever d, d' is caused to be tilted, and the
forked end d thus lifts the boss e out of contact with the driving surface of the
bevil pinion 6, thereby stopping the revolution of the spindle a.
The weighted end d of the lever d, d¹ falls beneath the projection and holds
the detector wire g* and box out of the way of the revolving wiper f.
It will be evident without illustration that the lever d, d may be actuated by a
second lever controlled by the detector wire g* box g and wiper but I prefer the
arrangement herein before described as being the more simple.
A second part of the invention is designed to enable the spindle to revolve more

page_text: steadily and also to allow of the said spindle being readily taken out thereby enabling
the cop to be more easily doffed.
At a convenient part of the machine on the top rail I fix a rod on which a
plate or bracket m slides, this plate m is formed at one end with a spring clip m*
(see detached plan Fig. 2.) which embraces the knob a* of the spindle a a groove
being cut or formed therein for that purpose see detached partial elevation on Fig. 4.
A bent spring m* is provided on this bracket or plate m which catches on to the
top of the rod when it is required to lift up the spindle a which it holds up out
of the way for the purpose of doffing or " piecing."
On the lower end of the knob a* 1 fix by a spring or other convenient arrange-
ment a disc or washer o which projects a little beyond the knob a* and bears on the
bobbin or cop on the said spindle a (see Fig. 4.).
Another part of the invention consists of a simple arrangement of mechanism
whereby I am enabled to stop the spindle a as soon as the cop has been completed,
and so to regulate this motion as to form a cop of any desired size.
To the plate or bracket in which rises with the pirn I attach a rod p extending
downwards; on this rod is an adjustable finger or projection which can be set
higher or lower to suit any length of cop required.
By the time the cop is completed this finger comes in contact with a projecting
arm p² on the oscillating box the movement of which stops the rotation of the bobbin
in the same way, as when an end of yarn breaks.
u
To assist the lifting of the spindle in cases where fine yarn is being wound 1
attach a small weight to the spindle preferably as shown at Fig. 1. (or to the
above named sliding plate m which steadies the spindle) by means of a cord or
chain passing over a pulley or bowl q2 mounted on any convenient fixed part of the
mechanism.
The weight will have a tendency to raise the spindle a as the cop is formed,
and will thus relieve the yarn of the greater part of the strain occasioned by the
lifting of the spindle.
I would here remark that in my Provisional Specification I described certain parts
of a reeling machine which I have since found not to be so novel and practically
useful as at first believed and 1 consequently wish to lay no claim to such con-
struction.
In frames wherein the yarn or thread is to be passed through a flame or gassed
(as shewn in sectional elevation at Fig. 5) instead of mounting the cradle » above the
winding drums s (as usual in such apparatus) so that the bobbin t rises as the yarn
is wound on, I mount it in front of the drums and thus I am enabled to get a
greater range of diameter of the yarn wound on the bobbin.
In order to maintain the bobbin in contact with the drum s I attach a weight
to the cradle by means of a chain or cord passing if desired over a rod or pulley,
suitably situated, or I otherwise apply a weight to the said cradle r.
The cradle is provided with an independent handle or latch and this handle or
latch is retained when the bobbin t is withdrawn by means of a latch lever v, 2.1
pivotted to the frame the inner end e¹ of which lever is made with a slot or hole,
and in the slot or hole works a finger w from the pivotted gas pipe .
The outer end of this latch lever rests on the handle or latch u or a projection u*
therefrom and is so weighted that when released to replace the bobbin t, on the
driving drums, this outer end will drop, raise the slot or hole at the other end
and put the gas flame into its working position.
In order to prevent this latch lever e, from dropping too soon, and putting the
gas flame into position beneath the yarn before the winding has commenced and thus
burning the same (or too late and thus forming an unfinished length of yarn) I make
this latch lever of such a form that as the said handle or latch
approaches the
driving drums the said lever v rests on the projection u* from the handle or latch u
for some distance and is then provided with an incline v2 which will allow it to drop
as soon as the projection u* reaches the said incline; and thus the attendant can
26

page_text: gradually cause the handle or latch u to approach the driving drums and imme-
diately the bobbin touches the latter he releases the handle or latch u altogether
and thus the latch lever will drop and move the gas flame simultaneously with the
commencement of winding.
When the latch u is raised until the projection * arrives at the notch, in the
lever v,
the projection u falls into the notch thus retaining the cradle and holding
up the bobbin t out of contact with the drum s.,
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. In "pin-cop" or "pirn" winding machines the combination with a wiper,
oscillating box and detector wires, of a bent lever or levers for automatically lifting
the driving boss out of contact with the bevel pinion or wharve (which drives the
spindles) whenever an end breaks.
2. In "pin-cop" or pirn winding machines the combination with the head or
knob of the spindle of a spring clip attached to a plate or bracket sliding on a
vertical rod for the purpose of steadying the spindle.
$3
3. In pin-cop" or pirn winding machines the combination with the arrangement
last above claimed of a rod attached to the said rising plate or bracket and provided
with an adjustable projection for tilting the oscillating box and thus raising the
driving boss out of contact with the bevil pinion or wharve by means of a forked
lever, or otherwise so as to stop the frame when the cop or pirn has attained the
desired height or length.
"3
"
4. ln " pin-cop or pirn" winding machines the use of weighted cords or
chains passing over pulleys for counterbalancing the weight of the spindle and its
adjuncts.
5. In "gassing" winding frames the combination with a pivoted gas pipe of a
notched catch lever and catch or their equivalent and weighted cradle whereby I
au enabled to bring bobbin into a lower position on the winding drum and thus to
wind bobbins of a larger diameter..
