1, WILLIAM THOMAS WATTS, of the firm of Taylor Lang & Co. Limited, of Castle
Iron Works Stalybridge, in the County of Chester, Machine Makers, do hereby declare
the nature of the said invention, to be as follows:-
My invention relates to the winding on motion of selfacting Mules and Twiners
and its object is to modify the winding on as the cop builds and the spindles
diminish in diameter by automatic means such arrangements of mechanism being
commonly termed "nosing motions."
In ordinary non-automatic nosing motions a stud carried on the radial arm has to
be adjusted by the "Minder
as the
cop builds, which stud is thus made to act
more and more upon the winding on chain-The mechanism hereinafter described
will be a convenient and simple arrangement even when adjusted by hand.
::
My invention consists in mounting an arm hereinafter termed the " nosing arm
on a fulcrum in a bracket secured to the radial arm, this nosing arm has a stud in, or
projection from it to act upon the winding on chain.
There is a ratchet pawl jointed on the nosing arm the free end of which enters
ratchet teeth in a segment formed on the bracket carrying the fulcrum of the
nosing arin.
One end of a helical spring is attached to the nosing arm the other end of which
spring is connected with a projection from the said bracket to pull and hold the
nosing arm and thus the pawl against the teeth of the ratchet.
By this means the pawl, ratchet and spring hold the nosing arm in any position
in which it may be placed in relation to the radial arm so that the projection carried
by it will come more or less as required against the winding on chain.
The nosing arm is made to come more and more against the winding on chain as
the cop builds by a chain or other suitable connection or connections and guides
transmitting direct or modified motion from the "shaper " to the nosing arm, which
is moved and altered in position when the radial arm has moved to its fullest extent

page_text: backwards but becomes slack and does not operate upon the nosing arm, when it is
acting upon the winding on chain.
Friction clutches or other arrangements may be substituted for the segmental
ratchet and pawl.
In some cases the connection from the copping rail is or may be made with a slide
or lever on the framing having a projection to act upon the nosing arm when the
radial arm has moved to near its full extent backwards.

1, WILLIAM THOMAS WATTS, of the firm of Taylor, Lang & Co., Limited, of
Castle Iron Works, Stalybridge, in the County of Chester, Machine Makers, 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 the winding on motion of selfacting mules and twiners
and its object is to modify the "winding on" as the cop builds and the spindles
diminish in diameter by automatic means, such arrangements of mechanism being
commonly termed "nosing motions."
In ordinary non-automatio nosing motions a stud carried on the radial arm has to
be adjusted by the "Minder" as the cop builds which stud is thus made to act more
and more upon the winding on chain.
The mechanism hereinafter described will be a convenient and simple arrangement
even when adjusted by hand.

My invention consists in mounting an arm hereinafter termed the "nosing arm
on a fulcrum in a bracket secured to the radial arm, this nosing arm has a stud in
or projection from it to act upon the winding on chain.
There is a ratchet pawl jointed on the nosing arm the free end of which enters
ratchet teeth in a segment formed on the bracket carrying the fulcrum of the
nosing arm.
One end of a helical spring is attached to the nosing arm, the other end of which
spring is connected with a projection from the said bracket to pull and hold the
nosing arm and thus the pawl against the teeth of the ratchet.

page_text: By this means the pawl, ratchet and spring hold the nosing arm in any position
in which it may be placed in relation to the radial arm so that the projection carried
by it will come more or less, as required, against the winding on chain."
The nosing arm is made to come more and more against the winding on chain as
the cop builds, by a chain or other suitable connection or connections and guides
transmitting direct or modified motion from the "shaper" to the nosing arm which
is moved and altered in position when the radial arm has moved to its fullest extent
backwards but becomes slack and does not operate upon the nosing arm when it is
acting upon the winding on chain.
Friction clutches nips or other suitable arrangements which hold in one direction
and are free in the other may be substituted for the segmental ratchet and pawl.
Fig. 1 is a side elevation in which parts of a selfacting mule are indicated, and fig. 2
is a plan view of parts shown in fig. 1. a is part of the framing, 6 the ordinary
radial arm and quadrant, e the rod between the shaper plates of the ordinary shaper
mechanism.
To the ordinary radial arm a bracket d is secured which has a stud d' in it, to form
the fulcrum of an arm or lever d² hereinafter termed the nosing arm, the end of which
carries a stud on one side for a bowl d³ (see fig. 2) which when the radial arm b
moves inwards will come upon the ordinary winding on chain which is connected at
one end to the screw nut of the radial arm, and at the other end to the ordinary
winding on drum; this winding on chain is not shown in the drawings.
On one side of the nosing arm d² a slot is formed for an adjustable stud upon
which a pawl d is jointed, the free end of this pawl comes upon ratchet teeth formed
upon a segmental part d*, of the bracket d having the fulcrum d¹ of the nosing arm d²
for its centre.
To the nosing arm d² one end of a helical spring d³ is secured, the other end being
connected with a projection de from the bracket d.
The spring d thus acts to draw the nosing arm d² towards it, but the pawl d* taking
hold of the ratchet teeth resists the pull of the spring and holds the nosing arm d² in
whatever position it is set.
.
When the bowl d³ on the nosing arm presses upon the winding chain, the strain
upon the nosing arm d² comes upon the pawl d' and ratchet segment d*.
As the cops build the nosing arm d² is pulled more and more from the spring d³.
This may be adjusted by hand, but is effected automatically by a chaine one end
of which is attached to the end of the nosing arm d² and then passes through an
eye in a bracket el secured to the floor or framing, the other end of the chain e is
then attached to one arm e² of a bell crank lever, which has its fulcrum e³ on a bracket
secured to the floor or framing, then one end of another chain or connection e¹ is
attached to the other arm e of the bell crank lever, and the other end of this chain
or connection e' is attached to a collar or bracket e adjustable upon the ordinary
rod c connecting the shaper plates of the ordinary shaper mechanism.
If desired there is or may be an adjustable collar on the shaper rod c, which
collar bas a stud to project from one side to enter a fork or slot formed in the
arm e of the bell crank lever, so that the bell crank lever will move to and fro with
the shaper rod c.
It will be understood that as the cop builds the chain e, will be moved in the
direction pointed by the arrow on fig. 2, and the arrows on fig. 1.
The chain e between the nosing arm d² and eye bracket e will be slack at all
times, except that this slack in the chain will be taken up when the radial arm b, is
fully back, at which moment the chain e will cause the nosing arm d² to move and
the pawl d to pass over and take hold of another tooth of the ratchet d* upon the
segment of the bracket d.
It should be understood however, that the nosing arm d² is not moved by the
chain e to take a fresh tooth at every back movement of the radial arm b, but is
only moved at intervals to cause the pawl d to take a fresh tooth when the chain e
has been advanced sufficiently by the shaper rod c, to produce in the nosing arm d³
movement to the extent of one tooth of the ratchet.

page_text: At the commencement of a fresh set of cops the pawl is lifted and the nosing
arm is allowed to be drawn hack by the helical spring ds, and the chain e will then
automatically bring the nosing arm to the correct position when it is required to
act upon the winding on chain the latter being away from and clear of the bowl d³,
while the bottom of the cop is being formed as is well understood.
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 of a radial arm with a nosing arm, pawl, ratchet and spring,
substantially as and for the purpose herein before described and illustrated by the
drawings.
2. The combination of a radial arm, nosing arm, pawl and ratchet or other
equivalents and springs with a chain or other connection and the shaper mechanism,
substantially as and for the purpose hereinbefore described and illustrated by the
drawings.
3. The combination and arrangement of nosing mechanism, substantially as herein-
before described and illustrated by the drawings.
