I, JOHN MCQUEEN, of John Hetherington and Sons, Limited, Vulcan Works,
Pollard Street, Manchester, in the County of Lancaster, Machine Makers, do hereby
declare the nature of this invention to be as follows:
My invention relates to improvements in self acting mules and the object of my.
improvements is to increase the weight put by the salmon head levers on the
fallers after the backing off operation and whilst the yarn is being wound on the.
spindles and to gradually ease the weight until the winding on operation has been.
completed.
In carrying my improvements into effect I support each salmon head lever upon
a movable fulcrum such as an anti-friction bowl carried by a stud in a slide fitted
in a suitable stationary bracket secured to the carriage the light end of the lever
being preferably guided in a slot formed to receive it in a bracket secured to the
carriage or otherwise suitable guided. The slide with the bowl or fulcrum is caused
to travel at the required time along the stationary bracket by any suitable gearing.
or device, as for example, by means of a spur wheel on the carriage actuated by a
stationary rack on the floor and transmitting its motion to a rack on the slide which
carries the fulcrum and as the slide is moved and the position of the fulcrum is
altered the weighted salmon head lever acts with diminished or increased effect
upon the fallers.
I may or may not extend the light end of the salmon head lever through the
slot in the bracket which guides it and weight it by weights or springs in any
convenient manner if advantageous or desirable.
I may apply my improvements to each salmon head lever or to any one or
more of such levers.

Improvements in self Acting Mules.
I, JOHN MCQUEEN, of John Hetherington and Sons, Limited, Vulcan Works,
Pollard Street, Manchester, in the County of Lancaster, Machine Makers, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
My invention relates to improvements in self acting mules and the object of my
improvements is to increase the weight put by the salmon head levers on the fallers
after the backing off operation and whilst the yarn is being wound on the spindles
and to gradually ease the weight until the winding on operation has been completed.

page_text: In carrying my improvements into effect I support each salmon head lever upon
a movable fulcrum such as an anti-friction bowl carried by a stud in a slide fitted
in a suitable stationary bracket secured to the carriage the light end of the lever
being preferably guided in a slot formed to receive it in a bracket secured to the
carriage or otherwise suitably guided. The slide with the bowl or fulcrum is
caused to travel at the required time along the stationary bracket by any suitable
gearing or device.
In the accompanying sheet of drawings-
Figure 1 is an elevation of part of a self acting mule to which my improvements
are applied, Figure 2 is a sectional elevation taken on the plane of the line A B,
Fig. 1. Figure 3 is a sectional plan taken on the plane of the line C D, Fig. 1.
In these views, a designates the carriage, 6 the tin roller, c the spindles, de the
faller shafts, f the salmon head lever, the ordinary weights and h the chains
connecting the salmon head lever to the faller shafts d e.
All the foregoing parts may be of the ordinary or any suitable construction.
To the carriage a I secure a slideway i which is fitted a slide j carrying a stud
on which is preferably mounted an antifriction bowl or roller k. To the slide j
is secured a rack gearing with a pinion m on the axle of which is fixed a spur
wheel gearing into a stationary rack o fixed on the floor. The antifriction
bowl forms a movable fulcrum for the salmon head lever f the light end of which
is shown slotted and guided by a bracket secured to the carriage a.
When the carriage during its run brings the wheel n into gear with the station-
ary rack o motion is transmitted by the pinion m and rack to the slide which
carries the fulcrum k consequently as the slide is moved and the position of the
fulcrum is altered the weighted salmon head lever f acts with diminished or
increased effect upon the fallers.
I may (or may not) extend the light end of the salmon head lever f beyond the
bracket as shown and weight it by weights s as shown or by springs in any con-
venient manner if advantageous or desirable.
I may apply my improvements to each salmon head lever or to any one or more of
such levers.
Instead of the gearing shown I may employ any equivalent arrangement of
mechanism for adjusting the position of the fulcrum at the required time.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. The combination with a weighted salmon head lever, connected to the faller
shafts, of a movable fulcrum the position of which is adjusted by mechanism
actuated at the required time during the travel of the mule carriage to regulate
the action and effect of the weighted salmon head lever upon the fallers.
2. The combination with a weighted salmon head lever f connected to the faller
shafts de, of the movable fulcrum k carried by the slide j and means, such as
the gearing shown, for actuating the same at the required time during the travel
of the carriage all substantially as and for the purposes herein set forth.
3. The general combination and arrangement of parts embodying my improve-
ments in self acting mules substantially as and for the purposes herein described
with reference to the accompanying drawings.
