PROVISIONAL SPECIFICATION.
Improvements in and applicable to Spinning Mules and Twiners.
We, JOSEPH BOWKER, of Hope House, Kersal, Manchester, in the County of
Lancaster, Cotton Spinner, CHARLES BUTTERWORTH, of 17, Queens Road,
Oldham, in the same County, Mill Manager, and THOMAS MCVAY, of 538,
Chamber Road, Oldham, aforesaid, Mule Overlooker, do hereby declare the
nature of this invention to be as follows:-
Our said invention has reference to improvements in and applicable to self-
acting mules and twiners, and relates particularly to the means employed to
lock the winding faller which controls the building of the cops as is well under-
stood.
If a mule cop is examined, the surface of the cop will be found uneven, a
series of ridges of yarn plainly appearing on the exterior. These ridges are
produced by reason of the yarn being more tightly wound in some parts than
others owing to the faulty action of the winding faller. This unevenness is
most marked about the base of the cop and is naturally more pronounced in
cops of the coarser counts. Cops so wound are not only less satisfactory in
appearance and finish but the yarn is under uneven tension and leaves the cop
more freely in some places than in others.
This uneven winding we have found to be due to uncertain and unauthorised
movements of the winding faller.
These uncertain movements of the winding faller are owing to the fact that
the boot leg of the faller locking lever does not always occupy the same position
relatively to the bowl on the trail lever, and to the fact that the position of such
locking lever is apt to vary during the run-in of the carriage.
As is well
known this faller locking lever is held by means of a spring when winding.
Owing to the presence of the copping plate, this spring exerts a greater pull
on the lever during the early part of the run-in of the carriage than during the
later part, so that the locking lever frequently alters its position during the
run-in of the carriage such alteration consequently affecting the position of the
winding faller.
According to our invention we provide means which ensure that the faller
locking lever shall always occupy the same position relatively to the bowl on
the trail lever and shall be locked in such position during nearly the whole of
the run-in of the carriage. By these means the faller locking lever is immov-
ably held and is not affected by the action of the spring.
Under a simple method of carrying our invention into effect we provide the
trail lever with a pivotted hook or catch adapted to engage a pin or stud secured
to the boot leg of the faller locking lever. This catch may be formed as a bell-
crank lever, one hooked arm engaging at the required time the pin or stud, the
other and pendent arm being arranged to encounter a bracket formed with an
inclined face and secured to the copping rail, so as to disengage the catch just

page_text: before the termination of the inward run of the carriage. The bracket keeps
the catch disengaged until the pendent arm leaves the incline on the next out-
ward draw of the carriage when the catch again falls into postion by its weight
assisted if necessary by a spring.
The action of the parts is as follows. As soon as backing-off takes place the
faller is drawn down by the action of a chain connected to the backing off-finger,
the faller locking lever being elevated in turn and drawn in, all as is usual.
Immediately the faller locking lever has been drawn in sufficiently far, the
pivotted catch drops over the pin or stud carried on the boot leg of the lever,
and the lever is thereupon immovably locked in position whereupon the inward
movement of the carriage commences. Just before the carriage terminates its
inward run and the fallers are unlocked, the catch is knocked off or disengaged
by reason of the pendent arm of the bellcrank encountering the incline bracket
secured to the copping rail as aforesaid.
Thus the position of the faller locking lever is always the same at the com-
mencement of, and during each inward run of the carriage, so that the winding
faller is not unfavourably influenced by such lever and more evenly wound cops
are produced.
We do not confine ourselves to the details herein indicated so long as a part
or parts is or are arranged to positively hold and lock the faller locking lever in
the same position during each inward run of the carriage, means being also pro-
vided to disengage such part or parts on the termination of such run.
Improvements in and applicable to Spinning Mules and Twiners.
We, JOSEPH BOWKER, of Hope House, Kersal, Manchester, in the County of
Lancaster, Cotton Spinner, CHARLES BUTTERWORTH, of 17, Queens Road,
Oldham, in the same County, Mill Manager, and THOMAS MCVAY, of 538,
Chamber Road, Oldham, aforesaid, Mule Overlooker, 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 and
accompanying drawings.
Our said invention has reference to improvements in and applicable to self-
acting mules and twiners, and relates particularly to the means employed to
lock the winding faller which controls the building of the cops as is well under-
stood.
If a mule cop is examined the surface of the cop will be found uneven a
series of ridges of yarn plainly appearing on the exterior. These ridges are
produced by reason of the yarn being more tightly wound in some parts than
others owing to the faulty action of the winding faller. This unevenness is
most marked about the base of the cop and is naturally more pronounced in
cops of the coarser counts. Cops so wound are not only less satisfactory in
appearance and finish but the yarn is under uneven tension and leaves the cop
more freely in some places than in others.
This uneven winding we have found to be due to uncertain and unauthorised
movements of the winding faller.

page_text: Figs. 6 shows a plan and side elevation of the bracket employed to disengage
the locking catch or pivotted lever towards the end of the inward run of the
carriage.
Fig. 7 indicates diagramatically the copping rail together with the locking
catch and disengaging bracket.
In carrying our invention into effect we provide the trail lever A with a
pivotted hook or catch a adapted to engage a pin or stud b secured to the lower
end or boot leg of the faller locking lever B. This catch is preferably formed
as a bell crank lever and is pivotted on the stud a' carried by the trail lever A
so that its hooked end or projecting nose a² may engage and be disengaged from
the pin or stud b. The hooked end or projecting nose a² of the lever a is pre-
ferably rendered adjustable by the provision of the set screw a passing through
the slotted end of the lever a as clearly indicated in Figs. 3 and 4. The pendent
arm of the lever a carries an adjustable tail piece at such tail piece being
arranged to encounter a bracket c secured by bolts or studs c¹ to the copping
rail or shaper plate d, so as to disengage the pivotted catch a just before the
termination of the inward run of the carriage.
The bracket c keeps the pivotted catch disengaged until the tail piece a leaves
on the next outward draw of the carriage when the catch again falls into position
by its weight assisted if necessary by a spring. We may if required employ a
stud or the like to limit the backward movement of the pendent limb of the
lever a.
In order to compensate for any variation in distance between the centre
of the pivotted lever and the pin or stud on the boot leg, due to the gradual
lowering of the copping rail, we form the inner bearing face a* with a slight

page_text: incline or bevel up which the pin or stud gradually bears so that the catch main-
tains a tight hold on the boot leg throughout the building of the cop.
In Fig. 1 of the drawings the carriage is supposed to be making its draw the
faller being unlocked whilst in Fig. 2 winding is taking place the faller is
locked and held immovable by means of our improved locking catch.
The action of the parts may be briefly described as follows. As soon as back-
ing-off takes place the faller is drawn down by the action of a chain connected
to the backing off-finger, the faller locking lever being elevated in turn, and
drawn in and held by the spring C, all as is usual. Immediately the faller
locking lever has been drawn-in sufficiently far, the pivotted catch a drops over
the pin or stud b carried on the boot leg of the lever B and the lever is thereupon
immovably locked in position (see full lines Fig. 7) whereupon the inward move-
ment of the carriage commences. Just before the carriage terminates its inward
run and the fallers are unlocked, the catch a is knocked off or held clear of the
stud b (see dotted lines Fig. 7) by reason of the pendent arm of the bell-crank
encountering the bracket c secured to the copping rail as aforesaid.
By the use of our invention the position of the faller locking lever on the
bowl is always the same at the commencement of, and during each inward run
of the carriage, so that the winding faller is not unfavourably influenced by
such lever and more evenly wound cops are produced.
We do not confine ourselves to the details herein indicated so long as a part
or parts is or are arranged to positively hold and lock the faller-locking lever in
the same position during each inward run of the carriage, means being also pro-
vided to disengage such part or parts on the termination of such run.
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 :-
1) In self-acting mules and twiners, locking the faller locker lever B so that
the same is held immovable, by means independent of the action of the spring C,
during the run-in of the carriage, in the manner, and substantially as described.
2) The improved means for immovably holding the faller-locking lever during
the run-in of the carriage consisting of the bell-crank lever a pivotted on the
trail lever and engaging a pin or stud on the boot leg of the faller-locking
lever the lever a being disengaged by a bracket c carried by the copping rail
substantially as described and shown.
