PROVISIONAL SPECIFICATION.
An Improved Automatic Nosing Motion for Self Acting Mules.
We, WILLIAM HAYTHORNTHWAITE, Mill Manager, WILLIAM TEMPEST,
Mechanic, and ALEXANDER GRADWELL, Spinning Master, all of Cherry Tree,
near Blackburn, in the County of Lancaster, do hereby declare the nature of this
invention to be as follows: :-
Our invention consists in an improved automatic nosing motion for self acting
mules for spinning.
One way of carrying our invention into effect is to secure to the copping faller
shaft an arm or finger which is for a greater part of the time inoperative but which
will automatically come into action at any desired part of the cops formation.
Then during the inward run of the mule carriage the arm or finger operates a
ratchet segment or wheel fixed on a stud carried in a bracket secured to the frame
side or other convenient part of the mule. On the other end of this stud is fixed an
eccentric (or various other suitable arrangements may be employed to gain the same
object) which when connected with an arm rod or lever or chain accelerates the
action of the winding on drum thereby increasing the tension on the yarn when
forming the cop nose.
As soon as the copping faller shaft has turned sufficiently the arm or finger
thereon comes into contact with a finger or projection fixed on the ratchet segment
at each inward run of the mule carriage; and gradually and intermittently turns it
tooth by tooth in one direction, a pawl or pawls preventing the ratchet segment and
the eccentric from turning back the forward movement of the eccentric or
projection, on the ratchet segment being communicated to either an arm rod lever
or chain whereby the winding on chain may be raised or depressed thereby
hastening the speed of the spindles at the desired time whereby better and firmer
cops are secured.
In order to automatically re-set the motion after doffing a catch or finger which
is secured to the copping faller comes against a spring catch pivoted on the frame
near the segment and lifts the pawl or catch out of gear with the ratchet teeth, a
spring then drawing the segment and eccentric back to their normal positions where
they remain until the nosing motion again comes into action.
According to another arrangement we employ a ratchet wheel and worm wheel
working concentrically on the same stud or shaft carried in a bracket and secured
to the frame side. This ratchet wheel is operated and moved say one tooth by the
faller during each inward run of the mule carriage while the nose of the cop is being
built; another toothed pinion wheel is made to gear into the worm wheel and on
the other end of the same stud or shaft another wheel gears into a vertical toothed
slide held in position in the usual way the motion from the ratchet wheel imparted
to the slide causes it to rise or fall or move various ways as may be most convenient
for actuating with a lever or rod or other suitable mechanism the winding on chain
and thus give extra movement to the spindle at the time when the cop nose is being
formed.

An Improved Automatic Nosing Motion for Self Acting Mules.
We, WILLIAM HAYTHORNTHWAITE, Mill Manager, WILLIAM TEMPEST,
Mechanic, and ALEXANDER GRADWELL, Spinning Master, all of Cherry Tree,
near Blackburn, in the County of Lancaster, 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 :-
Our invention consists in an improved automatic nosing motion for self acting
mules for spinning.
One way of carrying our invention into effect is to secure to the copping faller
shaft an arm or finger which is for a greater part of the time inoperative but which
.will automatically come into action at any desired part of the cops formation.
Then during the inward run of the mule carriage the arm or finger operates, a
ratchet segment or wheel fixed on a stud carried in a bracket secured to the frame
side or other convenient part of the mule. On the other end of this stud is fixed an
eccentric (or various other suitable arrangements may be employed to gain the same
object) which when connected with an arin rod or lever or chain accelerates the
action of the winding on drum thereby increasing the tension on the yarn when
forming the cop nose.
As soon as the copping faller shaft has turned sufficiently the arm or finger
thereon comes into contact with a finger or projection fixed on the ratchet segment
at each inward run of the mule carriage ;. and gradually and intermittently turns it
tooth by tooth in one direction, a pawl or pawls preventing the ratchet segment and
the eccentric from turning back, the forward movement of the eccentric or
projection on the ratchet segment being communicated to either au arm rod lever
or chain whereby the winding on chain may be raised or depressed thereby hastening
the speed of the spindles at the desired time whereby better and firmer cops are
secured.
In order to automatically re-set the motion after doffing a catch or finger which
is secured to the copping faller comes against a spring catch pivoted on the frame
near the segment and lifts the pawl or catch out of gear with the ratchet teeth, a
spring then drawing the segment and eccentric back to their normal positions where
they remain until the nosing motion again comes into action.
According to another arrangement we employ a ratchet wheel and worm wheel
working concentrically on the same stud or shaft carried in a bracket and secured
to the frame side. This ratchet wheel is operated and moved say one tooth by the
faller during each inward run of the mule carriage while the nose of the cop is being
built another toothed pinion wheel is made to gear into the worm wheel and on
the other end of the same stud or shaft another wheel gears into a vertical toothed
slide held in position in the usual way the motion from the ratchet wheel imparted
to, the slide causes it to rise or fall or move various ways as may be most convenient
for actuating with a lever or rod or other suitable mechanism the winding on chain
and thus give extra movement to the spindle at the time when the cop nose is being
formed.
And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying two sheets of drawings reference. being
had to the figures and letters marked thereon.
Fig. 1 is a side elevation of part of the frame of a self acting mule to which our
improvements are applied.
Fig. 2 is a similar view which illustrates the second part of our invention.
Fig. 3 is an end sectional view of part of Fig. 2 and Fig. 4 is a detail view and
Fig. 5 is an alternative arrangement of our invention.
In Fig. 1, a is the machine frame, 6 part of the mule carriage and c one of the
rails upon which the carriage runs, d is the quadrant driven from a pinion on the

page_text: shaft de the faller shaft and the copping faller shaft on which is secured an
arm; on the frame a is secured a bracket which carries a stud g¹ on which ia
secured a ratchet segment 93 provided with a projection g³, and on the same stud g¹
is also secured an eccentric or tappet 9; pivoted on the frame a is a pawl or
pawls which rest in the ratchet teeth on the segment 92 and a projection h on the
pawls is employed in connection with an elbow lever i, pivoted on the frame and
a finger secured to the copping faller shaft for re-setting the motion after a set
of cops has been doffed. To the quadrant dis secured one end of the winding on
chain, the other end of which is secured to the winding on drum, 6 carried, by the
mule carriage,. this chain is arranged to be acted upon automatically after the cops
have been partly built or at any desired point by a bowl. A mounted upon one end
of a lever pivoted at d² to the arm of the quadrant by means of the arm }
mounted upon the copping faller shaft f, this arm at each, inward run of the
carriage comes into contact with the projection g³ on the segment g² and moves.it,
the segment, being prevented from moving back by the teeth of the pawls / as,the
segment and its stud 9 are turned by the arm the eccentric.or tappet g* rises and
lifts the short arm of the lever I and so presses the bowl ' down upon the chain
thus taking up more of the chain and accelerating the speed of the spindles at, the
desired time whereby. better and firmer cops are produced.
The motion, is re-set automatically after doffing by the finger secured to the
copping faller shaft which comes into contact with the end of the pivoted lever i
as the mule, carriage makes its inward run and thus depresses the other end of the
lever i and an adjustable pin secured to it comes against the end h' of the pawls,h
and raises the latter out of gear with the ratchet teeth on the segment g³ and allows
a spring m to move the segment 9² stud 9 and, tappet. g back.to.their original
position. When the segment 92 has resumed its position a spring n brings the
elbow lever again, into its normal. position..

In Fig. 2 the quadrant d is not shown, and, the. lever is not employed. On the
carriage b is fixed an adjustable bracket o which at each run of the carriage: comes
into contact with and lifts an arm p pivoted upon a stud q fitted, in a small
bracket which in its turn is pivoted at upon a bracket secured to the frame a
the bracket is held in its normal position by a spring ³. The arm p rests upon a
studs carried by the bracket, rand, has a pawlup which turns the shaft q by the
ratchet wheel mounted on it, a worm 92 on a stud 9 gears into a wheel t on a
stud supported in the bracket and this wheel t gearing with a rack, u, moves it
in slideways u in the direction of the arrow, see Fig. 2, and thereby draws up the
auxiliary chain k which passes from the rack u round the pulley u³ to the winding
on chain k thus tightening it and accelerating the speed the spindles while the nose
of the cops are being built and building better and firmer cops.
In order to be able to vary the action of the chain upon the winding on
chain k in place of taking the chain k round the pulley u² as shown on Fig. 2, we
employ a lever provided with an adjustable stud at each end as shown at Fig. 4
and we make the chain in two parts one part being secured to the rack u and to
the stud at one end of the lever and the other part being secured to the stud at the
other end of the lever and to the winding on chain k so that by altering the position
of the stud or studs on the lever the action of the chain on the chain k may be
increased or diminished.
Fig. 5 illustrates a modification of the arrangements shown on Figs. 1 and 2, we
employ the parts mounted on the bracket r³ shown on Fig. 2, and we dispense with
the rack, we mount on the stud the eccentric or tappet g* so that it comes under
the end of the lever in the manner described in reference to Fig. 1, so that
when the lever is operated by the bracket o on the mule carriage the eccentric 9*
is turned and lifts one end of the lever / which acts upon the chain k as described
in reference to Fig. 1.
The motions shown on Figs. 2 and 3 are automatically re-set after doffing by the
finger on the copping faller shaft which comes into contact with a pivoted lever v
and depresses its lower end so that a study on it moves one end of the stud
q

page_text: downward and so forces the worm q² out of gear with the wheel t thus allowing a
spring w to draw back the rack u and slacken the chain k¹.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
1. In a self acting mule, the use of an arm on the copping faller shaft operating
a ratchet segment or wheel connected to an eccentric or tappet which moves a
lever so as to cause it to bear against the winding on chain and thereby accelerate
the action of the winding on drum to increase the tension on the yarn when forming
the cop nose substantially as and for the purposes herein described and as illustrated
on Fig. 1..
2. In a self acting mule, the combination with a lever, pawl, ratchet wheel,
worm, pinion and rack actuated by a bracket or equivalent on the mule carriage,
of a chain connected to the rack and to the winding on chain for actuating the
latter substantially as and for the purposes herein described and as illustrated by
Figs. 2 and 3 of the accompanying drawings.
3. In a self acting mule, the combination with the winding on chain, of an
additional chain or chains connected to adjustable studs mounted on a pivoted lever
substantially as and for the purposes described in reference to Fig. 4.
4. In a self acting mule, the combination with a lever, pawl, ratchet wheel, worm
and pinion, operated by a bracket or equivalent on the mule carriage, of an
eccentric fixed on the stud on which the said pinion is fixed, which eccentrio
actuates a lever which bears upon the winding on chain to accelerate the action of
the winding on drum substantially as and for the purposes herein described and as
illustrated by Fig. 5.
5. The several arrangements and combinations of parts embodying the improve-
ments substantially as herein described and as illustrated by the several drawings
annexed.
