PROVISIONAL SPECIFICATION.
Improvements in Self-acting Mules and Twiners.
I, JOHN THOMAS AINSWORTH, of 35 High Street, Bolton in the County of Lancaster,
Mill Manager, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved easing motion for self-acting mules and twiners
and the chief object of my invention is to ensure the underfallers rising smoothly and
steadily and so to prevent breakage of the yarns when the backing off takes place and
further to build better and harder cops than is practicable with the mechanism now
ordinarily employed to raise the underfaller.
In carrying the first part of my invention into effect I employ a spring or
equivalent connected at one end to an arın secured on the underfaller shaft and at the
other end to one arm of a small elbow lever fulcrumed on a bracket secured to the
front of the carriage; the other arm of this elbow lever is connected by a rod or spring
to a hanging arm or catch pivoted on a bracket secured say to the back of the carriage.
An adjustable stop or bracket is secured to the floor in such a position that as the
carriage is on the point of completing its outward run the hanging arm comes against
the stop and is thus prevented moving forward with the carriage while it makes say
the last inch of its run, the effect of which is to tighten the spring connected to the
arm on the underfaller shaft. As soon as the salmon head lever comes into action to
lift the underfaller the latter rises against the resistance of the spring whereby a
steady and smooth motion of the faller is insured until the faller has reached its
highest position.
When the backing off has been completed the carriage begins its inward run and
the hanging arm in receding from the stop allows the different connections to resume
their original positions and thus the tension on the spring is quickly and stea lily
relieved until the carriage again approaches the end of its outward ran.
An important advantage obtained by the use of my improved easing motion is that
it is practicable to increase considerably the weight on the salmon head lever and so
to build better and harder cops.

Improvements in Self-acting Mules and Twiners.
1, JOHN THOMAS AINSWORTH, of 35 High Street, Bolton, in the County of Lancaster,
Mill Manager, 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 :-
My invention relates to an improved easing motion for self-acting mules and twiners
and the chief object of my invention is to ensure the underfallers rising smoothly and
steadily and so to prevent breakage of the yarns when the backing off takes place and
further to build better and harder cops than is practicable with the mechanism now
ordinarily employed to raise the underfaller,

page_text: In carrying the first part of my invention into effect I employ a spring or
equivalent connected at one end to an arm secured on the underfaller shaft and at the
other end to one arm of a small elbow lever fulcrumed on a bracket secured to the
front of the carriage; the other arm of this elbow lever is connected by a rod or
spring to a hanging arm or catch pivoted on a bracket secured say to the back of the
carriage. An adjustable stop or bracket is secured to the floor in such a position that
as the carriage is on the point of completing its outward run the hanging arm comes
against the stop and is thus prevented moving forward with the carriage while it
makes say the last inch of its run, the effect of which is to tighten the spring
connected to the arm on the underfaller shaft. As soon as the salmon head lever
comes into action to lift the underfaller the latter rises against the resistance of the
spring whereby a steady and smooth motion of the faller is ensured until the faller has
reached its highest position.
When the backing off has been completed the carriage begins its inward run and
the hanging arm in receling from the stop allows the different connections to resume
their original positions and thus the tension on the spring is quickly and steadily
relieved until the carriage again approaches the end of its outward run.
An important advantage obtained by the use of my improved easing motion is that
it is practicable to increase considerably the weight on the salmon head lever and so
to build better and harder cops.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying two sheets of drawings reference being had to
the figures and letters marked thereon.
Figure 1 is a side view of part of a self-acting mule to which my invention is
applied and
Figs. 2 and 3 are similar views of alternative arrangements.
In Figure 1.-a is part of a mule carriage, the underfaller or counterfaller shaft
and e the winding or copping faller shaft, their respective faller wires being lettered b
and c; to the underfaller shaft is secured an arm or bracket & which carries a
swivel piece at its free end to receive the screwed rod e' of a coiled spring e which is
connected below to one arm of a small elbow lever f pivoted on a bracket g secured to
the front of the carriage Cl Fixed on the floor is a stop which has an adjustable top
piece which is placed so that the hanging leg f1 of the lever comes into contact
with it just before, say about an inch or an inch and a half before the carriage arrives
at the end of its outward run.
As soon as the carriage is at the end of its outward run and latched, the weighted
salmon head lever, not shown, comes into action to lift the underfaller and the
latter rises against the resistance of the spring e which is held taut by the leg f' being
pressed against the stop piece i whereby a steady and smooth motion of the faller
wire is insured until it has reached its highest position.
While the backing off is taking place, the springs e relieve the backing off motion
of a great part of the additional and ordinary weight on the salmon head levers and
the moment the carriage begins its inward run the leg f gradually leaves the stop
piece whereby the tension on the spring e and underfaller b' begins to be taken off
thus allowing the underfaller wire to rise steadily and smoothly while the yarn is
being wound upon the spindles and as soon as the carriage has travelled a short
distanco on its inward run the leg will have left the stop piece and all tension
have been thus taken off the spring e, so that the parts forming my improved easing
motion remain at rest until the carriage is completing the next outward run.
In Fig. 2 a finger f" is pivoted at the back of the carriage a and connected by a
rodj or it might be a spring to the elbow leverf which is pivoted at the front of the
carriage a. The stop piece is placed proportionately nearer the headstock and the
action of the parts is similar to that described with reference to Fig. 1. In place of
the rigid stop piece shown and described in Figs. 1 and 2 a spring stop K might be
employed as shown in Fig. 3.
By the use of my improved easing motion as described it is possible to weight
the salmon head lever more heavily than usual and yet to get a smoother and

page_text: steadier movement of the underfaller by means of the tension put into the spring
which relieves the underfaller of a great part of the weight put upon it when the
backing off is effected, consequently less strain is put upon the yarn, fewer ends
are broken and better and harder cops are built.
I wish it to be understood that I may apply a single easing motion only, as
described, or two or more of my improved easing motions to each underfaller shaft. I
find in practice that two such easing motions to each underfaller shaft give a
good result.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that I am aware that
it has previously been proposed to balance the salmon head lever for purposes similar
to those of my invention and I make no claim at large to such balancing, but what
I claim is:-
In a self acting mule or twiner-
1. The arrangement use and application of an arm or bracket fixed upon the
underfaller shaft and connected by a spring connection to an elbow lever pivoted
to the mule carriage in combination with an adjustable or spring stop on the floor
substantially as and for the purposes herein set forth.
2. The combinations and arrangements of parts constituting my improved easing
motion substantially as and for the purposes herein described and as illustrated by
Figs. 1 and 2.
