7 Improvements in or connected with Mules for Spinning Yarn.
We, JOSEPH JONES, Assistant Manager, and JAMES WILLIAM MORRISON,
Mechanic, both at Tame Side Mills, Dukinfield, in the County of Chester, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the faller actuating or controlling
mechanism of self-acting mules and constitutes an easing or relieving motion
whereby the weight or strain put upon the yarns by the under or counter faller can
be gradually altered or adjusted as the position of the carriage and the position or
operation of the faller render the yarn more or less capable of bearing a given
strain.
It is designed with the object of reducing the weight acting on the under fallers
during the operation of backing off and winding on of the binding threads upon
the cone of the cop, and to increase the weight thereon after those operations have
taken place when the condition or position of the yarn render it able to bear a
greater tension or strain.
The invention consists essentially in the application to the faller lever of a
movable or sliding weight which gradually alters its position to and from the
fulcrum upon which the lever is pivoted so as to present a less or greater weight
upon the end of the lever as desired.
In carrying out the invention we mount upon the faller lever a movable or sliding
weight whose position on the lever relative to the pivot or fulcrum can be readily
altered.
.
The gradual moving of the weight to and from the fulcrum of the lever can be
effected in several ways. We prefer to mount the weight on rollers or balls to
reduce friction so that it will offer but little resistance in being moved along the
lever and motion may be imparted to it as required by means of a lever of switch-
back or other form, springs, inclined stops, bands or racks.
At present we prefer to form the faller lever with an incline at the outer end
and another at the required distance from the fulcrum between which the sliding
weight is free to move. On the floor is fixed an inclined stop against which the
movable weight comes in contact when the carriage has moved out the desired
extent. The movement of the weight with the carriage and lever is thereby
arrested and the lever passes on through the weight as the carriage moves forward.
The fulcrum of the lever thus gradually moves towards the weight reducing the
weight exerted upon the faller lever. The incline on the stop further reduces the
weight on the lever as the movable weight moves up and rests thereon. The inclines
on the faller lever facilitate the movement of the weight at each end of its travel
when the direction of movement of the lever is changed and the incline at the outer
end further lifts the weight up to clear the incline on the fixed stop.
The movement of the sliding weight as the carriage and faller lever run in and
out may be retarded in other ways such as by a friction band bearing against or
engaging with the weight; a stop rod attached to the weight and connected with
or pivoted to a fixed or sliding bracket; by a pivoted lever operated by the
carriage as it moves over the lever; or by a rack and pinion similarly actuated.
The method of altering the relative position of the weight to the fulcrum is not
essential the main feature of the invention being a weight sliding on the faller
lever whereby additional weight or tension is given to or taken off the yarn as is
required.
When in operation most weight is relieved during the backing off and the weight
is gradually given back or increased during the winding of the binding threads.

page_text: The greatest amount of weight is therefore upon the lever or sustained by the
under or counter faller at a point beginning where the threads of yarn commence
their upward direction of motion or winding from base of cone to apex of same.

COMPLETE SPECIFICATION.
Improvements in or connected with Mules for Spinning Yarn.
We, JOSEPH JONES, Assistant Manager, and JAMES WILLIAM MORRISON,
Mechanic, both at Tame Side Mills, Dukinfield, in the County of Chester, 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 improvements in the faller actuating or controlling
mechanism of self-acting mules and constitutes an easing or relieving motion
whereby the weight or strain put upon the yarns by the under or counter faller can
be gradually altered or adjusted as the position of the carriage and the position or
operation of the faller render the yarn more or less capable of bearing a given
strain.
It is designed with the object of reducing the weight acting on the under fallers
during the operation of backing off and winding on of the binding threads upon the
cone of the cop, and to increase the weight thereon after those operations have
taken place when the condition or position of the yarn render it able to bear a
greater tension or strain.
The invention consists essentially in the application to the faller lever of a
movable or sliding weight which gradually alters its position to and from the
fulcrum upon which the lever is pivoted so as to present a less or greater weight
upon the end of the lever as desired.
The invention will be fully described with reference to the accompanying
drawings in which a portion of the carriage of a mule sufficient for illustrating
it is shown.
Fig. 1. Front elevation.
Fig. 2. Transverse sectional elevation.
Fig. 3. Plan.
The carriage A the winding faller B the counter faller C the salmou head or
faller lever D and the connections or attachments between the fallers and the
lever D are all of any well known or ordinary construction.
To the faller lever D we apply or connect a movable or sliding weight E whose
position can be readily or gradually altered as the carriage A runs in and out to
increase or diminish the effective weight applied to the lever D by moving the
weight E in relation to the pivot or fulcrum of the lever.
The invention may be effectually applied in several ways:-
At present we prefer to rest the movable weight E upon a secondary lever F
fixed to the carriage front, the end of which engages with the end of the lever D,
as shown in the drawings. The lever F is pivoted to the adjustable bracket G by
the stud and is preferably set on an incline so that the weight E can travel down
by its own gravity. The end of the lever F is provided with a forked bracket or
stud which engages with the end of the faller lever D. To the sliding weight E is
attached a chain or band H which passes over a guide or carrier I affixed to the
front of the carriage and thence to a stationary bracket J affixed to the floor at the
back of the mule to which it is secured.
Instead of using the secondary or auxiliary lever F to carry the weight E the
weight may rest and slide up the faller lever D itself the top of the lever being

page_text: inclined or formed of suitable shape for the purpose the weight being moved by a
band or other suitable means.
It will thus be seen that the weight may be placed so as to travel at right angles
to or parallel with the direction of movement of the carriage. In the former case
the weight is moved or controlled by a band and in the latter case may instead of a
band be moved or controlled by a stop, spring, rack, stop rod or similar contrivance
with which it might come in contact and by means of which the movement of the
weight with the carriage and lever may be arrested and the lever passes on through
the weight as the carriage moves forward.
The method of altering the relative position of the weight to the fulcrum is not
essential the main feature of the invention being the application of a weight
sliding to the faller lever whereby additional weight or tension is given to or taken
off the yarn as is required.
When in operation the weight E is in the position shown at the commencement
of the outward traverse or draw of the carriage and as the carriage recedes from
the roller beam and reaches the end of the traverse the weight E is by the pull of
the band H gradually moved along the lever F until it reaches the position shown
in dotted lines. During this movement the weight exerted on the faller lever D
gradually decreases until the weight passes the fulcrum of the lever when it tends
to raise or support the end of the faller lever. By this means the greater portion
of the weight applied to the faller lever D is relieved from the connecting chain d
and from the counter faller C during the backing off motion thus reducing the strain
upon the yarn. As soon as the carriage starts on its inward traverse and the
winding commences the weight E gradually slides down the incline of the lever
giving a steady increasing tension to the yarn during the winding operation the
full weight or amount of tension being applied when the winding has reached to the
shoulder of the cop, for the reason that were the full weight applied before the winding
faller B began to rise there would be extra strain on the threads as the winding faller
would be pulling the threads down while the counter faller was pulling upward.
The tension is then uniform during the winding from the shoulder to the nose of
the cop or during the completion of the inward run of the carriage.
This invention has an additional advantage in that it does not retard the
movement of the free end of the faller lever D which is not uniform throughout the
spinning consequent upon more yarn being backed off the spindles when the cops
are small than when nearly finished. This variation being equivalent to from two
to three inches the end of the lever F rises and falls as required to adjust itself to
the position of the faller lever D.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a mule for spinning yarn the application to the faller lever of a movable or
sliding weight the position of which is gradually altered or adjusted by the
traverse of the carriage to reduce or relieve the weight on the faller lever and the
tension on the yarn during the operation of backing off and to gradually increase
the weight or tension when the winding commences substantially as described.
2. In a mule for spinning yarn the combination with the faller lever D of the
sliding weight E the secondary lever F upon which the weight slides and the
stationary band H which moves the weight E substantially as and for the purposes
described.
