Improvements in the Winding Motion of Self-acting Mules.
We, ARTHUR TAYLOR, of 78, Co-operative Buildings, Bradford Road West,
Batley, in the County of York, Designer, and ERNEST FIRTH, of Whitelee, Batley,
aforesaid, Woollen Spinner, do hereby declare the nature of this invention to be
as follows:-
This invention relates to the winding motion of self-acting mules and the object
of our improvements is to substitute for the present quadrant, a scroll motion by
means of which we obtain a much more uniform action in the traverse of
the chain for regulating the speed of the spindles when they are winding up the
yarn.
For the purpose of our invention we employ a suitable form of scroll mounted
on a shaft journalled in bearings in the framework of the end-piece of the mule
at the extremity of the "draw" said scroll having attached to and wound thereon
the outer end of the winding chain whose opposite end is secured to and wound
on the winding barrel in the ordinary way. On the outer end of the scroll shaft is
a pinion or toothed wheel which gears with the threads of a long screw or wort
secured rotatively by key and feather to a vertical shaft upon which it is capable
of being raised and lowered to give motion to the scroll shaft, and also of being.
rotated by said vertical shaft to adjust the position of the scroll rotatively for the
purpose of starting the action of the winding chain from any given point of the
scroll according to the description of the yarn being spun, or the size of the cop
and also as to whether winding on to the bare spindle or on to paper tubes, or for
any other reason which requires any adjustment in the point of initial delivery of
the chain.
To a boss or lugs at the lower end of the screw or worm are secured two chains.
whose opposite ends are attached to a barrel mounted on the outer end of a shaft
carrying a spur wheel which gears with a pinion mounted on the same shaft
as the ordinary grooved pulley from whence the motion for actuating the scroll is
obtained. When the carriage travels out from the beam, motion is communicated
through the pinion and spur wheel to the lifting barrel which winds on the two
chains and thereby draws the screw or worm a given distance up the vertical shaft
said screw acting as a rack and turning the scroll one revolution, or more or less
as determined upon, whereby the length of winding chain necessary to rotate the
spindles at the proper speed when winding on is taken up by the scroll in readiness
for paying out when winding commences. When the chain delivers or pays out
from the smallest diameter or volute of the scroll the winding is at the maximum
and in order to adjust this position of delivery gradually from the commencement
of the winding until the abrupt taper is completed or full diameter of the cop
reached to regulate the winding accordingly, we use the ordinary endless band
which is at present employed to adjust the position of the sliding block in the
quadrant, said band passing around a pulley secured on the lower end of the vertical
shaft, so that each time said band is traversed as ordinarily the vertical shaft and
also the screw or worm thereon are rotated with the result that the scroll shaft is
turned partially around and changes the position of initial delivery of the chain

progressively until the full diameter of the cop-is reached after which the chain
delivers from the same portion of the scroll to the full completion of the cop.

The above described winding motion gives a more uniform action than the
quadrant now employed and can be applied to any make of self-acting
mule.

Improvements in the winding motion of self-acting Mules.
We, ARTHUR TAYLOR, of 78, Co-operative Buildings, Bradford Road West, Batley,
in the County of York, Designer, and ERNEST FIRTH, of Whitelee, Batley, aforesaid,
Woollen Spinner, 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 to the winding motion of self-acting mules, and the object
of our improvements is to substitute for the present quadrant, a scroll motion by
means of which we obtain a much more uniform action in the traverse of the 1
chain for regulating the speed of the spindles when they are winding up the
yarn.
For the purpose of our invention we employ a suitable form of scroll mounted on
a shaft journalled in bearings in the framework of the end-piece of the mule at the
extremity of the "draw" said scroll having attached to and wound thereon the
outer end of the winding chain, whose opposite end is secured to and wound
on the winding barrel in the ordinary way. On the outer ond of the scroll shaft is
a pinion or toothed wheel which gears with the threads of a long screw or worm
secured rotatively by key and feather to a vertical shaft upon which it is capable
of being raised and lowered to give motion to the scroll shaft, and also of being
rotated by said vertical shaft to adjust the position of the scroll rotatively for the
purpose of starting the action of the winding chain from any given point of the
scroll according to the description of the yarn being spun, or the size of the cop
and also as to whether winding on to the bare spindle or on to paper tubes; or for
any other reason which requires any adjustment in the point of initial delivery of
the chain. To a boss or lugs at the lower end of the screw or worm are secured
two chains whose opposite ends are attached to a barrel mounted on the outer end
of a shaft carrying a spur wheel which gears with a pinion mounted on the same
shaft as the ordinary grooved pulley from whence the motion, for actuating the
scroll is obtained. When the carriage travels out from the beam, motion is
communicated through the piuion and spur wheel to the lifting barrel which winds
on the two chains and thereby draws the screw or worm a given distance the
vertical shaft, said screw acting as a rack and turning the scroll one revolution, or
more or less as determined upon, whereby the length of winding chain necessary to
rotate the spindles at the proper speed when winding on is taken up by the scroll
in readiness for paying out when winding commences. When the chain delivers
or pays out from the smallest diameter or volute of the scroll the winding is at the
maximum and in order to adjust this position of delivery gradually from the
commencement of the winding until the abrupt taper is completed, or full diameter
of the cop reached to regulate the winding accordingly, we use the ordinary
up

page_text: endless band which is at present employed to adjust the position of the sliding
block in the quadrant, said band passing around a pulley secured on the lower end
of the vertical shift, so that each time said band is traversed as ordinarily, the
vertical shaft and also the screw or worm thereon are rotated with the result that
the scroll shaft is turned partially around and changes the position of initial delivery
of the chain progressively until the full diameter of the cop is reached, after which
the chain delivers from the same portion of the scroll to the full completion of the
cop.
A hand lover or wheel may also be provided for rotating the vertical shaft
for purposes of adjustment by hand.
In the accompanying drawings illustrating our invention,
Fig. 1 is sectional side elevation of so much of the outer end piece of the
headstock of a self-acting mule, and of the mule carriage, as is essential to shew the
application of our improvements.
Fig. 2 is opposite side elevation of the end piece of the mule.
Fig. 3 is end elevation looking in the direction of arrow Fig. 2.
Referring to the drawings, letter p represents a scroll mounted on a shaft p¹,
journalled in bearings in the framework a one end of the shaft projecting beyond
the framework, and having a pinion secured thereon. This pinion p¹¹ meshes
with the thread of a vertical screw or worin q, on a vertical shaft q', supported at
the upper end in a bracket a¹, and at the lower end resting in a footstep a". The
screw or worm q is secured rotatively to said shaft q' by a key working in a key-
way cut in the shaft and is free to move vertically thereon, within the limits of its
length. On the shaft q', and under the lower end of the screw or worm q, is placed
a loose boss or plate q¹¹ having hooks q secured thereto, to which hooks are
attached the ends of two chains ?, ?, whose opposite ends are secured to a barrel l
mounted on a shaft 11 journalled in bearings in the framework a. On the shaft 11,
is a spur wheel 111, which meshes with a pinion s on the shaft s', whereon is mounted
the ordinary grooved pulley s¹¹, around which is wound the cord s which drives
the winding motion. This shaft s¹, forms the first motion shaft of our improved
winding motion, and when it is rotated by the machine to draw out the mule
carriage, the motion is conveyed through the gears 8 and 11 to the shaft 11, which
rotates the barrel r¹, and causes to wind on the chains ", ", whereby the screw or
worm q, is drawn up the shaft q' from the position shewn in full line in Fig. 2 to
that shewn in dotted line, same figure, this vertical upward movement of the
screw q, acting as a rack on the pinion p", thereby rotating the scroll shaft p¹ to
the extent of one revolution, which is the amount of movement we find to answer.
The rotation of the scroll takes up the winding chain t, which is secured at one end
to the largest diameter of the volute of the scroll p, and at its opposite end in the
ordinary way to the winding barrel u, which by suitable gearing drives the spur
wheel u which meshes with the pinion c¹¹ on the tin cylinder shaft c¹ as heretofore.
The winding chain t is fully wound around the scroll p at the commencement of the
building of the cops and delivers first from the smallest diameter of the volute
of the scroll, and then from the larger diameter of said scroll, which gives the
amount of unwinding of the chain required, in precisely the same manner as the
ordinary quadrant, but with a much more uniform motion. The greatest amount of
winding-ou takes place when the chain is paid out from the smallest diameter of
the scroll, this being gradually decreased as the abrupt taper of the base of the cop
is built up by the shifting of the initial point of delivery of the chain further and
further up the volute of the scroll until the full diameter of the cop is reached, when
the delivery takes place, from the highest point reached on the scroll, throughout
the remainder of the winding-on of the yarn, the action following in all respects that
of the ordinary quadrant for regulating the rate of speed of the spindles in winding
on the yarn.
The adjustment of the scroll rotatively to regulate the rate of speed of the
spindles is effected by the same endless cord which is at present employed to
adjust the sliding block in the quadrant, to which the end of the winding chain is
attached. This cord v is passed around a grooved pulley q¹ secured to the lower

page_text: end of the vertical shaft q¹. When the cord is traversed by frictional contact from
the well known mechanism on the headstock provided for that purpose, it turns the
vertical shaft q', and therefore the screw or worm q, which through pinion p" gives
a partial rotation to the scroll p and thus adjusts its position self-actingly to regulate
the speed of the spindles. The scroll p may also be set in the first instance to
deliver from any point thereof, according to the class of yarn being spun or for like
reasons, by means of a hand lever q* fitted on the upper end of the vertical shaft q¹.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In the winding motion of self acting mules, the use and employment of a scroll
for determining the unwinding of the winding chain from the winding barrel and
regulating the rate of speed at which the spindles shall be driven whilst the yarn
is being wound, such said scroll taking the place of and performing the function of
the ordinary quadrant and being actuated in the manner and by the means,
substantially as herein shewn and described.
2. In the winding motion of self acting mules, the combination with the winding
barrel and winding chain of a scroll, a screw or worm, a pinion on the scroll shaft
together with the means for raising said screw or worm, and for rotating it to give
motion to the screw to take up the chain and to adjust it rotatively to regulate the
speed of the spindles all arranged as described.
