Improvements in Self-acting Mules.
We, WILLIAM LEWIS HOLLAND, of the Adelphi Works, Preston, in the
County, of Lancaster,, Machine Maker, and JOHN ECKERSLEY, of 15, Brixey
Street, in, the same town, Mechanical Engineer, 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 an improved arrangement of apparatus known as an

vary the tension on the yarn during the winding on of the cop so that the said
tension may be gradually decreased as the yarn is wound on to a gradually

!
On the vertical face of a metal bracket or angle plate fastened to the front and
lower sides of the mule carriage we mount a stud or axis on which a toothed bevel
wheel is free to rotate the said wheel. being operated or rotated by a pinion wheel
on the upper end of a vertical shaft whose lower end carries a fast pulley or drum
around which is wound a cord or band the two ends of which are fastened
respectively to stands on the floor one in front and the other behind the carriage or
wheel race.
In practice however we find a horizontally arranged shaft more
convenient. Upon the back or plate part of the bevel wheel we fasten a "heart
cam against whose lower edge an anti-friction bowl on the free end of an arm
pivoted at its other end upon the front of the bracket is caused to press by being
lifted against the said cam by the pull of a vertically arranged helical spring whose
lower extremity hooks on to the free end of the pivoted arm and whose upper
extremity hooks on to the end of an arm fast to and projecting from the counter-
faller rod. In practice we find it more convenient to arrange the pivoted arm 'and
friction bowl above the heart cam than below it as just described. The apparatus
is so arranged that when the mule carriage recedes and the winding on operation
commences (at the smallest diameter of the cop) the movement of the cam
gradually increases the pull of the helical spring on the counter-faller wire until
the winding on reaches the largest diameter of the cop and then gradually decreasés
until the smallest diameter of the cop is again reached. When the carriage again
moves outwardly the pulley and bevel wheels are rotated in the opposite direction
the cam being thus returned or brought round again to its former position by the
time the carriage reaches the end of its outward traverse ready to accommodate.
itself to the winding on operation when the carriage again recedes.
In the accompanying drawings
Fig. 1 shews our improved easing motion in side view, and
Fig. 2 is a front view of part of the same detached from the mule carriage.
Fig. 3 is a front elevation of the heart cam pivoted lever and helical spring
detached and illustrating-in solid lines-the relative positions of the said cam
and lever when the pressure on the yarn is increased and-in broken lines-when it
is decreased.

The said Figs. 1 to 3 refer to the arrangement of apparatus we employ when it is
to be applied to "stripping" mules in which the fallers are locked during the
outward stretch of the carriage. The succeeding figs. refer to a modification of the
above in order that our invention may be made applicable to "backing-off" mules
in which the fallers are not locked during the outward stretch of the carriage.

This shaft may be rotated either by means of pitch chain gearing n
actuated by the ordinary "squaring shaft" (as shewn at Fig. 1) or by any other 4
covenient mechanism or by means of a rope or band o-having its two ends fastened
to stands on the floor-wound round a pulley or drum (as shewn at Figs. 4 and 5).

In Figs. 4 to 8 the lever fis bent and the spiral spring e is connected thereto in
close proximity to the friction bowl which is 'held down on the face of the cam P.
by the pull of the horizontal spring which is fastened at one end 'to 'the free end
of the bent lever fand at its other end to a 'bracket or pin's on the plate In
order to keep the lever fand spring e absolutely inoperative during the outward
traverse of the mule carriage we employ a locking device preferably arranged in
the following manner. On the plate we mount a vertically hinged arm or bracket 5
whose upper end t'meets the underside of a lip on the lever fand 'holds up or
sustains the friction bowl and lever f in the position shewn at Fig. 5 during the
'

page_text: outward traverse of the carriage that is to say whilst the camp on its return
movement commences and continues to rotate in the direction of the arrow (see
Fig. 8) from the position shewn at Fig. 8 until it reaches the position shewn at
Fig. 6 where it will be observed the arm t has just been disengaged or withdrawn
from under the lip on the lever thus having allowed the friction bowl to drop
on to the camp which thereupon starts back in the opposite direction-during the
inward traverse of the mule carriage-as indicated by the arrow at Fig. 6 (see also
Fig. 7)-until it again reaches the position shewn at Fig. 8. The arm t is moved
round on its axis or hinge at the right time against the pull of a helical spring w
(see Figs. 4 and 5) from under the lip by means of the pin a projecting from the
back or furthest side from the spectator looking at Figs. 5, 6, 7, and 8-of the
wheel which meets as it rotates a projecting part or arm y and thus moves
the arm t partially round on its axis.
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 :-
The improved easing motion consisting essentially of the combination of a
cam, a pivoted lever, and a helical spring with the counter-faller rod of a self-
acting mule the said parts being constructed, arranged, and operating substan-
tially as hereinabove described and shewn in the drawings for the purpose specified.
