Improvements in the Winding Faller Lifting Motion of Self-acting
Mules and Twiners.
We, ASA LEES AND COMPANY LIMITED, of Soho Iron Works, Oldham, in the
County of Lancaster, Machine Makers, and JOHN CLEGG, of the same address,
Manager of the Mule Department, do hereby declare the nature of this inven-
tion to be as follows:-
Our invention relates to improvements in the winding faller lifting motion
of self acting mules and twiners, and the object of our improvements is to
govern the rise of the fallers at the termination of the inward run of the car-
riage and whilst the remainder of the unwound yarn is being coiled on the
bare spindles above the noses of the cops in such a manner as to lay the coils
more exactly evenly and uniformly than has hitherto been possible with the
ordinary lifting motions.
<
In carrying our improvements into effect we pivot the "boot leg" lever as
usual to a sector on the winding faller shaft and connect this or another sector
on the same shaft by a chain to an intermediate pulley on an adjustable shaft
on which is also fixed another pulley connected on the opposite side by the
monkey" chain to one side of a chain pulley loose on the tin roller shaft and
to the other side of this chain pulley is connected a second chain which passes
over guide pulleys and has a counterweight suspended from it to keep the
monkey chain constantly tight. The chain pulley is formed with or fixed to a
disc or plate to which is pivoted a spring click or pawl above a ratchet wheel
keyed on the tin roller shaft. The spring click is normally held out of gear
with the ratchet wheel by means of a cone fitted to slide on the tin roller shaft
to and from the ratchet wheel. The sliding movements of the cone are effected
by an elbow lever connected by a link to a latch lever controlled by a latch
pivoted on the ordinary link which connects the boot leg lever to the ""monkey
tail" lever which is fulcrumed on a rocking shaft as usual.
When the carriage reaches the end of its inward run and the boot leg lever
is moved off its fixed stop in the ordinary way, the monkey tail lever moving
with it by means of its latch draws back the latch lever and by the connections
therefrom slides the cone away from the ratchet wheel the spring click is
thereby allowed to drop into gear. As the tin roller shaft rotates the monkey
chain which controls the lifting movement of the winding faller is wound on

page_text: to the intermediate pulley and unwound from the chain pulley on the tin roller
shaft and as the chain pulley is secured to the click disc which at this time is
in gear with the ratchet wheel it follows that the unwinding of the chain pulley
and the rise of the winding faller are controlled exactly in accordance with the
rotation of the tin roller shaft. The lifting motion is released and reset auto-
matically by the continued forward movement and the return movement of the
reciprocating monkey tail lever.

Improvements in the Winding Faller Lifting Motion of Self-acting
Mules and Twiners.
We, ASA LEES AND COMPANY LIMITED, of Soho Iron Works, Oldham, in the
County of Lancaster, Machine Makers, and JOHN CLEGG, of the same address,
Manager of the Mule Department, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
1
Our invention relates to improvements in the winding faller lifting motion
of self acting mules and twiners, and the object of our improvements is to
govern the rise of the fallers at the termination of the inward run of the car-
riage and whilst the remainder of the unwound yarn is being coiled on the
bare spindles above the noses of the cops in such a manner as to lay the coils
more exactly, evenly and uniformly than has hitherto been possible with the
ordinary lifting motions.
In carrying our improvements into effect we pivot the "boot leg" lever as
usual to a sector on the winding faller shaft and connect this or another sector
on the same shaft by a chain to an intermediate pulley on an adjustable shaft
on which is also fixed another pulley connected on the opposite side by the
"monkey" chain to one side of a chain pulley loose on the tin roller shaft and
to the other side of this chain pulley is connected a second chain which passes
over guide pulleys and has a counterweight suspended from it to keep the
monkey chain constantly tight. The chain pulley is formed with or fixed to a
disc or plate to which is pivoted a spring click or pawl above a ratchet wheel
keyed on the tin roller shaft. The spring click is normally held out of gear
with the ratchet wheel by means of a cone fitted to slide on the tin roller shaft
to and from the ratchet wheel. The sliding movements of the cone are effected
by an elbow lever connected by a link to a latch lever controlled by a latch
pivoted on the ordinary link which connects the boot leg lever to the "monkey
tail lever which is fulcrumed on a rocking shaft as usual.
In the accompanying sheet of drawings-
Fig. 1 is a side elevation of so much of a self acting mule as is necessary to
illustrate the application of our improved winding faller lifting motion, and
Fig. 2 is a plan view of part of Fig. 1.
In these views,-1 designates the boot leg lever pivoted as usual to a sector 2
on the winding faller shaft 3; a sector 4 on this same shaft is connected by a
chain 5 to a double chain pulley 6 mounted upon a shaft supported in adjust-

page_text: able bearings not shown; the pulley G is also connected by the monkey chain 7
to one side of a chain pulley 8 loose on the tin roller shaft 9, and to the other
side of this pulley is connected a second chain or rope 10 which passes over guide
pulleys 11 only one of which is shown and is connected to a weight, which keeps
the monkey chain 7 constantly tight. The chain pulley 8 has a flange to which
is pivoted a spring click or pawl 12 above a ratchet wheel 13 keyed on the tin
roller shaft 9, and this pawl has an arm 12* and is held normally out of gear
with the ratchet wheel by means of a cone 14 on which the arm 12* rests, the
cone being fitted to slide on the tin roller shaft to and from the ratchet wheel.
The sliding movements of the cone are effected by an elbow lever 15 fulcrumed
at 16 and connected by a link 17 to a latch lever 18 fulcrumed at 19 on the
mule carriage, and connected to the back of the carriage by a coiled spring 20.
To the lever 18 is secured a catch piece 21 over which is hooked the latch 22
pivoted on the link 23 which connects the boot leg lever 1 to the monkey tail
lever 24 which is fulcrumed on the monkey tail shaft 25. The monkey tail
lever is connected as usual to the frame of the carriage by a coiled spring 26
and it carries at its end an adjustable screw 27 for litting and supporting the
latch 22. The boot leg lever is supported at certain times upon the locking
stud 28 and carries the usual unlocking finger 29 which when the carriage com-
pletes its inward run comes against a stop 30 secured to the floor plate.
The drawing represents the carriage when it has nearly completed its inward
run the pawl 12 being held by the cone 14 out of gear with the ratchet wheel 13,
and the boot leg lever at the moment resting upon the locking stud 28. As
soon as the unlocking finger 29 meets the stop 30, and as the faller is unlocking,
the boot leg lever will be forced back, the effect of this is to draw back the
link 23, the latch 22 and the latch lever 18 toward the boot leg lever, thus by
the link 17 and elbow lever 15 moving the cone 14 away from the ratchet
wheel 13 and arm 12 and so allowing the pawl to fall into gear with its teeth.
Then as the boot leg lever I falls and the winding faller begins to rise by
the connected chain 5 it winds the monkey chain 7 on to the intermediate
pulley 6 as fast as the chain 7 is unwound from the pulley 8 and since the
click 12 is at this time in gear with the ratchet wheel 13 it follows that the
unwinding of the monkey chain 7 from the pulley 8 and the consequent rise
of the winding fallers are absolutely dependent upon and controlled in exact
accordance with the speed of rotation of the tin roller shaft.
The continued descent of the boot leg lever 1 eventually causes the screw 27
to lift the latch 22 and release the latch lever 18 thus allowing the spring 20
to actuate the elbow lever 15 and slide the cone 14 up to the ratchet wheel 13
thereby disengaging the pawl 12.
At the next change when the winding faller descends and the boot leg lever
is raised and re-set in the usual way, the screw 27 leaves the latch 22 and allows
it to engage over the catch piece 21 the parts resuming the positions shown in
the drawings with the pawl 12 out of gear with the ratchet wheel 13.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed we declare that what
we claim is:-
In the winding faller lifting motion of a self acting mule or twiner-
1. In combination, the boot leg lever pivoted to a sector on the winding faller
shaft, a chain connecting said shaft to a pulley on an intermediate shaft, said
pulley being connected by the monkey chain to a loose pulley on the tin roller
shaft to which pulley is also connected a weighted chain or rope to keep the
monkey chain constantly tight, the parts being so arranged that when the faller
is unlocking suitable connections from the boot leg lever put into gear
pawl with a ratchet wheel fast on the tin roller shaft and so render the unwind-
ing of the monkey chain and the rise of the winding faller entirely dependent
upon the speed of the tin roller shaft substantially as illustrated and described.
