Year: 1884

page_text: ЛОЛОМАШ DI PUITICATION.
We, GEORGE KEIGHLEY, of Bankhouse Iron Works, Burnley, Lancashire,
Machine Maker, and FERD ROSSKOTHEN, of Avenue Parade, Accrington, Lancashire,
Engineer do hereby declare the nature of our invention for "IMPROVEMENTS IN
SPINNING MACHINERY," to be as follows:-
The first part of our Invention has reference to ring spinning and doubling
frames, and our improvements therein consist in the employment of means or
apparatus for reducing the drag upon the thread between the traveller and the
spindle or bobbin.
It is understood that when winding upon a bare spindle or bobbin, the direction
of the thread from the traveller is almost in a direct line with the centre of the
ring, consequently there is considerable drag upon the thread at this part, which
drag has a tendency to pull the traveller into contact with, or against the outside
of the ring, which when it occurs nearly always breaks the thread.
To remedy this is the object of our Invention, which we accomplish by placing
upon the upper end of the spindle a disc of larger diameter than the ring, the said
disc having either a smooth or serrated rim. The thread in passing from the guide
eyes to the traveller, bears upon the outside of the disc, and as it is larger in
diameter than the ring, the traveller is thereby pulled outward, and caused to bear
against and in contact with the inside of the ring, therefore breakages of the thread
by the travellers contact with the outside of the ring is avoided.
Secondly. In the employment of a second guide eye, in addition to the ordinary
guide eye for the purpose of regulating the friction or tention of the thread upon
the disc.
This additional guide eye has an upward and downward motion given to it,
independantly of the upward and downward motion of the rail carrying the ring
and traveller, the said motion of the guide eye being obtained by "heart wheel"
other well known mechanism.
ог
The guide eye is arrange to rise and fall in some relative proportion to the rising
and falling of the ring rail, as it is necessary to put more friction on the thread,
when winding upon the smaller part of the spindle, bobbin, or cop, than when
winding upon the largest diameter of the cop, therefore the guide eye is made to
approach the disc, so as to increase the friction on the thread when it is being
wound on the point or nose of the cop, but the said guide eye is arranged to recede
t

page_text: further from the disc, so as to reduce the friction on the thread when it is being
wound upon a larger diameter of the cop, consequently the tension upon the thread
is regulated as required by the reciprocatory guide eye.
Thirdly. The disc can also be employed for regulating the tension on the thread
when an inverted flyer is employed, driven by a band passing around a wharle on
the bottom of the said flyer. In this case the spindle is caused to rotate by the
thread, which thread when winding upon the thick part of the cop, will open out
or "balloon" because the tension on the thread is not great, when however the
thread is being wound upon the point or nose of the cop, the tension is increased,
causing the "balloon" to collapse, and the thread to assume a more perpendicular
line, the disc however keeps the tension off the thread, which would otherwise
become too great. This disc has a serrated edge or rim, and as long as the tension
on the yarn is not too great, it forms a "balloon," and does not touch the disc, but
as soon as the tension becomes great, the thread will touch the rim of the disc, and
enters one of the grooves, whereby the spindle will be further assisted in its
rotation thereby, until the tension of the thread becomes less, when the "balloon
is again formed and the thread is again clear of the disc. In conjunction with this
description of spinning machine, the second guide eye similar to that already
mentioned is employed.
"
"
Fourthly. When using rings of small diameter it is found difficult to "piece-up
broken ends, as it is impossible to reach or get hold of the end of the thread with
the fingers, in consequence of the smallness of the rings.
To overcome this difficulty we apply suitable mechanism for stopping the
rotation of the spindle.
The apparatus we employ in addition to the wharle for driving the spindle
_consists in another wharle running loosely upon_the_spindle,_and_in_the_means_or_
method of transferring the driving band from the fast to the loose wharle.
For this purpose we employ a fork, provided with a wedge shaped projection,
both of which are attached to one piece of metal, and capable of sliding in a
groove, so that when the driving band is required to be passed from over the fast
wharle to the loose one, the fork is drawn forward causing the wedge to lift up
both wharles, and in so doing the strap passes from the upper wharle to the lower
one, and the spindle is stopped thereby, leaving both hands at liberty to find and
piece up the broken ends.
The reverse motion of the wedge changes the driving band from the loose to the
fast wharle, and the spindle is again caused to rotate.
Instead of the pullies being raised by a wedge, for the purpose of transferring
the driving band from one pulley to another, they may be raised by a lever or
other equivalent.

We, GEORGE KEIGHLEY of Bankhouse Iron Works, Burnley, in the County of
Lancaster Machine Maker, and FERD ROSSKOTHEN of Avenue Parade, Accrington
in the County of Lancaster, Engineer do hereby declare the nature of our
invention for "IMPROVEMENTS IN SPINNING MACHINERY" and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
The first part of our Invention has reference to ring spinning and doubling
frames, and our improvements therein consist in the employment of means or
apparatus for reducing the drag upon the thread between the traveller and the
spindle or bobbin.
It is understood that when winding upon a bare spindle or bobbin the direction
of the thread from the traveller is almost in a direct line with the centre of the
ring, consequently there is considerable drag upon the thread at this part which
drag has a tendency to pull the traveller into contact with or against the outside
of the ring and the thread is broken thereby.
In order that this part of our Invention may be better understood, we herein
give reference to the accompanying Sheets of drawings, wherein Fig 1 is elevation
of spindle, ring and traveller in ordinary use shewing position of thread from the
guide eye 1 to the traveller 2.
As is well known the traveller is pulled around by the part of the thread 3 and 4
which is between the traveller and the spindle; and that if the diameter of the
spindle is very small the drag on the thread 3 and 4 becomes so great as to draw
the traveller against the outside edge of the ring 5, the frictional contact of which
causes the traveller to stop and break the thread.
To prevent this we place a disc 6 having either a smooth or serrated rim on the
top of the spindle (see Fig 2) the said disc being rather larger in diameter than
the ring 5 and as the thread in passing from the guide eye to the traveller bears
against the disc, it has a tendency to pull the thread with it, and exerts a drag on
the traveller against the inside of the ring consequently the stoppage of the
traveller by frictional contact with the outside of the ring is avoided.
Secondly. In the employment of a second guide eye (in addition to the ordinary
guide eye) for the purpose of regulating the friction or tension of the thread upon
the disc.
This part of our Invention is shewn in Fig 3 where 1 and 7 are the guide eyes,
the latter or additional guide eyes being fixed to a rail 8 which receives an upward
and downward motion by heart wheel, or similar well known motion independently
of the ring rail. The guide eye is arranged to rise and fall in some relative
proportion to the rising and falling of the ring rail. As it is necessary to put more
friction on the thread when winding upon the smaller part of spindle, bobbin, or
cop, than when winding upon the largest diameter of the cop, the guide eye is
made to approach the disc, so as to increase the angle of the thread when it is
being wound on the point or nose of the cop, but the said guide eye is arranged to
retire or recede further from the disc, so as to reduce the angle of the thread when
it is being wound upon a larger diameter of the cop, consequently the tension upon
the thread is regulated as required by the reciprocatory guide eye,

page_text: Thirdly. The disc can also be employed for regulating the tension on the thread
when an inverted flyer is employed driven by a band passing around a wharle on
the bottom of the said flyer.
This part of our Invention is shewn in Fig 4 where 9 is the inverted flyer caused
to rotate by band upon wharle 10. In this case the spindle 11 is pulled around by
the thread 3 and 4, therefore when winding upon the thick part of the cop and the
balloon" as shewn in dotted
tension is not too great the thread will open out or
line 12, when however the thread is being wound upon the point or nose of the
cop, the tension is increased to such an extent as to cause the "balloon" to collapse
and the thread to assume a more perpendicular line as shewn by dotted line 13, the
thread in this case bears upon the disc thereby keeping the tension off the thread,
which would otherwise become too great.
This disc has a serrated edge or rim, and as long as the tension on the yarn is
not too great it forms a "balloon" and does not touch the disc, but as soon as the
tension becomes great the thread will touch the rim of the disc, and enter one of
the grooves, whereby the spindle will be further assisted in its rotation, until the
tension on the thread becomes less when the "balloon" is again formed and the
thread is again clear of the disc. In conjunction with this description of spinning
machino the second guide eye similar to that already mentioned may be employed.
Fourthly. When using rings of small diameter it is found difficult to "piece up"
broken ends, as it is impossible to reach or get hold of the end of the thread with
the fingers because of the smallness of the rings, consequently the spindle has been
stopped by the knee of the attendant.
"
To overcome this difficulty we apply suitable mechanism for stopping the rotation
of the spindle.
The apparatus we employ in addition to the wharlo for driving the spindle
consists in another wharle running loosely upon the spindle and in the means or
method of transferring the driving band from the fast to the loose wharle, and this
is shewn in the accompanying drawings where Figs 5, 6, 7, Sheet 1, and Fig. 8, 9, 10
Sheet 2 are sections and elevations.
17 is the spindle rotating in the long collar 18 which is fixed to a rail by
adjustable nut 19.
The spindle is driven by the wharle 20 fixed thereon, whilst 21 is a loose wharle
running upon the long collar 18, the upper end of which enters half way up the
wharle 20.
A fork and band guide is shewn at 22, the rear end of which is provided with a
wedged shaped projection 23 which fits into a dovetail groove 24 formed in the
flange 25 of the long collar. If therefore an end has broken on any of the bobbins,
the attendant draws the fork 22 forward, causing the wedge 23 to slide under the
loose wharle 21 whereby the spindle and both wharles are raised as shewn in
Fig 7 and in so doing the driving band 26 slips off the upper wharle onto the
lower one, consequently the rotation of the spindle is stopped leaving both hands
of the attendant at liberty for "piecing up." The reverse motion of the wedge
changes the driving band from the loose to the fast wharle, and the spindle is again
caused to rotate.
Instead of the pulleys being raised by a wedge for the purpose of transferring
the driving band from one pulley to another, they may be raised by a lever as
shewn in Sheet 2 where in this case the band guide 22 is a fixture, being made
secure in the collar 25.
The lifting lever or trigger 27, is hinged to the collar 25 and when the spindle is
running satisfactorily the several parts assume the position shewn in Fig 9, but if
an end is broken, the attendant pulls the trigger 27 down with his hand, causing
the toe piece 28 to lift the wharle up as shewn in Fig 10, consequently the driving
band is transferred from the top to the bottom pulley and the spindle is stopped
thereby. When the ends are 'pieced" the trigger is lifted back again, and to
insure that both wharles shall descend when the toe piece is removed from under
the bottom wharle, we employ a finger 29 which rests upon the upper surface of
"

page_text: the top wharle, so that when the forward end of the trigger is raised; the finger 28
will push the wharles down, thereby making both the upper and down motions
positive.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
Firstly. The use and employment of a disc having a diameter larger than tho
ring, or larger than the circle formed by the extremities of the flyer legs, for
purposes set forth, and shewn in Figs 2, 3, and 4.
Secondly. The use and employment of a second thread guide operated in the
manner and for the purposes substantially as described and shewn in Fig 3.
Thirdly. The arrangements of apparatus substantially as shewn in Sheets 1 and 2
whereby the wharles and spool are raised, and the driving band transferred from
the fast to the loose wharle, and the spindle stopped thereby.
