PROVISIONAL SPECIFICATION.
A New or Improved Automatio Nosing Motion for Self-acting
Mules or Twiners.
I, ALBERT AINLEY of 72 Bentley Street, Lockwood, Huddersfield, Yorkshire,
Mill Manager, do hereby declare the nature of this invention to be as follows:-
This invention relates to automatic means for building up the nose of the cop or
winding the yarn in conical layers upoù the bar taper spindles or tubes employed
in self-acting mules or twiners, and the object of my improvements is to combine
with the building or winding mechanism in such machines, means which will
accelerate the speed at which the spindles are driven in proportion as the diameter
upon which each successive layer of yarn is wound, decreases, and in this manner
obtain a more perfect build of the nose of the cop throughout.
In carrying out my invention 1 suitably connect or engage with the "trail"
lever or slide, or other piece of mechanism performing like functions, or which is
adapted to follow the motion of the copping rail, in the building of the cop, a lever,
or two lovers jointed together, or a crank or cam which acts on a slide, lever,
or bar, carrying a stud, upon which may, if desired, be mounted a drum or grooved
pulley. The said stud or the grooved pulley is adapted to engage the underside
of the winding chain which gives the requisite rotary motion to the drum for
driving the spindles, and it is elevated so as to take up more and more of the
winding chain from the initial to the terminal winding of the yarn on the spindle by
the determining motion of the copping rail, "trail" lover, or slide transmitted
through the lever or levers or crank, above named whereby the terminal velocity of
the spindles as the cop nose is wound on a higher point or decreased diameter
thereof, is accelerated in proportion to the varying diameter, and this goes on at
each successive winding until the completion of the cop, which is thus firmly built
or wound to the shape required, and the liability of a spongy nose being
forined in avoided. Instead of the motion of the trail" lever, which acts in
unison with the copping rail, slide or other equivalent piece of mechanism, or of
the copping rail itself, which by my invention I utilise for accelerating the terminal
velocity of the spindles in proportion as the yarn is wound upon a constantly
decreasing diameter, being transmitted through a lever, levers, crauk, cam, or other
connecting mechanism, I may employ a chain, band, or wire passing around small
pulleys, or other suitable form and arrangement of connecting link or links for
the communicating motion to the stud or grooved pulley engaged with the winding
chain.

The parts berein named are preferably made adjustable so that the amount of
motion of said parts or the maximum height to which the stul or grooved pulley or
drum is to be raised, may be altered or raised to suit requirements.

pulley to be raised to take up more & more of the winding chain as the build of
the cop proceeds, by mounting the saine on a bracket or sliding block adapted to
bo raised and lowered on a screw actuated by a fixed stop or a part of the machine
engaging with a shaped or ratchet wheel fast on said screw, which is thereby :

A New or improved Automatio Nosing motion for self-acting
Mules or Twiners.
ALBERT AINLEY, of 72, Bentley Street, Lockwood, Huddersfield, Yorkshire,
Mill Manager, do hereby declare the nature of this invention and in what manner
the anime is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention relates to automatic means for building up the nose of the cop or
winding the yarn in conical layers upon the bare taper spindles or tubes employed
in self-acting mules or twiners, and the object of my improvements is to combine
with the building or winding mechanism in such machines, means which will
accelerate the speed at which the spindles are driven in proportion as the diameter
upon which each successive layer of yarn is wound decreases, and in this manner
obtain a more perfect build of the nose of the cop throughout.
In carrying out my invention 1 suitably connect or engage with the "trail" lever or
slide, or other piece of mechanisin performing like functions, or which is adapted to
follow the motion of the copping rail, in the building of the cop, a lever, or two levers
jointed together, or a crank or cam which acts on a slide, lever, or bar, carrying a stud,
upon which may, if desired, be mounted a drum or grooved pulley. The said stud or
the grooved pulley is adapted to engage the underside of the winding chain which
during the run of the carriage gives the requisite rotary motion to the drum for
driving the spindles, and it is elevated so as to take up more and more of the
winding chain from the initial to the terminal winding of the yarn on the spindle
by the determining motion of the copping rail, "trail" lover, or slide transmitted
through the lever or levers or crank above uamed whereby the terminal velocity
of the spindles as the cop nose is wound on a higher point or decreased diameter
thereof, is accelerated in proportion to the varying diameter, and this goes on
continually at each successive winding until the completion of the cop, which is
thus firmly built or wound to the shape required, and the liability of a
$6 spongy
nose being formed is avoided. Instead of the motion of the "trail" lever, which
acts in unison with the copping rail, slide or other equivalent piece of mechanism,
or of the copping rail itself, which by my invention utilise for accelerating the
terminal velocity of the spindles in proportion as the yarn is wound upon a
constantly decreasing diameter, being transmitted through a lever, levers, crank,
cam, or other connecting mechanism, I may employ a chain, band, or wire passing
around small pulleys, or other suitable for and arrangement of connecting link
or links for communicating motion to the stud or gooved palley engaged with the
winding chain.
"
The parts herein named are preferably made adjustable so that the amount of
motion of said parts or the maximum height to which the stud or grooved pulley
or drum is to be raised, may be altered or varied to suit requirements.
In order that my said invention may be more fully understood relerence is herein
had to the accompanying sheet of drawings wherein Fig. 1 is transverse section of
so much of a self-acting mule or twiner as is necessary to show the application of
my invention thereto; and Fig. 2 is a front elevation of part of same.
Referring to the drawings A represents the framework of the headstock of a

page_text: self-acting mule or twiner and B the travelling carriage in which the spindles E
are supported. On said carriage are mounted the winding drum F and tin
cylinder G, the latter for driving the spindles and the former for giving
The
motion to said cylinder during each inward run of the carriage.
drun F is rotated by the unwinding therefrom of a chain H, one end of which
is fast to said drum and the opposite end secured to the sliding nut 1' on the
quadrant I. J represents the "copping rail" and K the shoe or bracket supporting
the slide or trail lever whose vertical movement following the profile of the
copping rail gives motion to the winding faller, sickle, and soctor forming the
motion for giving the required chase or build to the cop.
All these said parts and the manner of operating them are ordinary and in
themselves form no feature of my invention which consists in utilising the motiou
of the trail lever or slide (whichever may be employed) or the profile and angular
positions of the "copping rail," or other part of the cop building mechanism
actuated from the "copping rail," for the purpose of gradually accelerating the
speed at which the spindles are driven during each run-in of the carringe in
proportion to the diminishing diameter of the higher portion of the spindles
upon which each successive layer of yarn is wound. In employing the "copping
rail," or parts passing over and deriving vertical movement froin same, as the
factor for determining the variation in the velocity of the winding drum and
therefore of the spindles in winding yarn onto the cop, especially when building
the nose of the cop, I secure a continuity of movements in winding, accurately
following the ordinary motion for building the cop and therefore reliable, certain
and sensitive to every variation in speed required, and giving a perfect and firm
build to the nose of the cop; the adjustment of the "copping rail" to vary the
build of the cop also adjusts correspondingly the means for accelerating the speed
of the spindles in winding.
One method or arrangement of means for utilising the motion of the "slide" or
trail lever derived from the "copping rail" is illustrated in Figs. 1 and 2 and
consists of a lever a pivotted at a to a bracket bolted to any convenient part of
the carriage or frame moving therewith where there is sufficient room for the parts.
The lever is connected at one end by rod c to the shoe K, or to what is called the
"slide" or the "trail lever," one or other of which is ordinarily employed for
following the profile and angle of the "copping rail" J and actuating the cop
building mechanism. The opposite end of said lever a is connected by rod or
link d to a plate e adapted to slide up and down in ways e in a bracket bolted to
the carriage, said plato carrying a stud which occupies a position immediately
under the winding chain H. When the building of the cop commences, the
lever a is slightly oscillated on its fulcrum by the vertical movement of the shoe K
"slide
01' "trail lever," as it follows the profile and angular position of the
"copping rail" at each inward run of the carringo B, and the vertical movement
being in a downward direction from the point J' of the " copping rail," it follows
that the lever a will be moved on its ceutre in the direction indicated by the arrows
and therefore raise the slide to a proportionate extent, thereby bringing the
stud finto engagement with the winding chain H, which is thus gradually elevated
at the point of contact during each run-in of the carriage, and, as the angle of the
copping rail" varies, as is well known, from the initial to the terminal winding of
the cop, so in the same ratio does the extent to which the stud fis elevated during
each successive winding of a layer of yarn on the cop vary,eas the yarn is wound
on a higher point and smaller diameter of the spindle.

The deflection of the chain If from a straight line drawn from the periphery of
the drum to the sliding nut I' causes the drum to be rotated at an increased
velocity to what would otherwise be the case, because of a greater length of chain
being drawn off the drum and the extent of snch deflection therefore determines
the gradually increasing velocity at which the drum shall be rotated throughout
the winding of the cop, the increase being in the same ratio as the constantly
diminishing diameter upon which the successive layers of yarn are wound upon the

page_text: conical nose of the cop and determined as previously described by the ordinary
cop building motion.
e
In Figs. 3 to 7 1 shew various modifications of means for transmitting motion
from the "copping rail," "slide," or "trail lever" for deflecting the winding
chain. In Fig. 3 the lever a is mounted at or near to the bottom of the carriage
and the slide is provided with a friction pulley which rests upon said lever and is
raised and lowered in unison with the oscillation thereof. Fig. 4 shows a crank
which may also be employed, the stud for deflecting the chain being either
attached to one arm of said crank or to a slide or lever adapted to be worked by
the crank arm.
In Fig. 5 a double lever is shewn which may elevate the stud ƒ by means of a
chain attached thereto which passes over a pulley and is connected to a pivotted
lever to which the stud fis secured somewhat as illustrated in Fig. 6 or in Fig. 7.
Instead of lovers, links, and chains as set forth the requisite motion may be
transmitted through racks and pinions. It will of course be obvious that the exact
method and arrangement of the parts for transmitting motion from the cop building
mechanism to tho deflecting stud fmay be varied and altered in many ways, both
for efficiency and to suit the amount of space which can be conveniently occupied
on the different makes of mules and twiners, without departing from the main
feature of my invention.
It will also be understood that the intermediate mechanism may be actuated
from a slot, groove or projection formed in or on the copping rail and following
the exact profile thereof; or from an auxiliary rail parallel therewith and arranged
in the same way or reversely or from any suitable part of the cop building
mechanism following the profile and angle of the "copping rail." Instead of the
stud fa drum or grooved pulley may be employed. The pivot of the lever a or its
equivalent, and the stud/are made adjustable so that the amount of motion of
said lever and the slide, and the position of the stud can be varied as required.
Should the "copping rail" and winding chain be on the same side of the head-
stock, the intermediate connection although similar to that shewn on the drawings
would be more direct.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the saine is to be performed, I declaro that what. I
claim is :-

carrying a stud or pulley such as fadapted to engage the winding chain and deflect
it to varying extents in the mauner and for the purposes substantially as heroin
shewn and described.
