PROVISIONAL SPECIFICATION.
An Improved Nosing Motion for Self-acting Mules.
JAMES ALFRED HOLT, Mechanic 3 Adelaide Street Southport Lancashire, I do
hereby declare the nature of this invention to be as follows:-
I attach a bracket of suitable shape to the side of the headstock-framing to this
bracket I attach a lever with a half circle rack or pawl cast together the said lever
to work on a stud. I likewise attach a catch to work on a stud to the same bracket
for keeping the lever into its place as it is gradually pulled into its position by a
small spring and chain which is connected to the ordinary shaper plates or rods by
suitable brackets, I likewise attach a second lever to the ordinary quadrant nut or
to a bracket attached to the quadrant by a stud so that as the quadrant osilates
backwards and forwards it comes in contact with the lever which is secured to the
framing and gradually presses the ordinary winding chain more and more as
the shaper works forward and as the cops build up the spindles instead of using the
chain I can use a jointed finger and connect it to the copping faller shaft so as to
come in contact with the lever which is connected to the bracket on the side of the
headstock framing and as the cops build up the spindles it will cause the lever to
press more and more on the lever which is connected to the quadrant and will cause
the spindles to revolve quicker as the shaper works forward and as the mule
carriage runs near to the roller beam.

An Improved Nosing Motion for Self-acting Mules.
I, JAMES ALFRED HOLT, Mechanic, late of 3 Adelaide Street, Southport,
Lancashire, now of 341 Shaw Road, Oldham, in the same County, 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 what is known as the "nosing motion" of self-acting
mules, whereby the chain extending between the "winding on drum" and the
"radial arm
is acted upon at about the time the yarn or thread is being wound
upon what is called the "nose" of the cop; such motions acting to take up a short
length of the winding on chain to cause the spindles to rotate faster at the time
required. Many of the nosing motions in use effect this object to some extent, but
not at the right time, and to the extent required for perfect winding on.
"
My improved nosing motion acts not only to bend or deflect the winding on chain
at the time required, as in ordinary nosing motions, but the arm carrying the nosing
pin, stud or bowl, has also a movement imparted to it that operates to draw off
chain from the winding on drum to the required extent and at the time required,
and thus the "winding on" becomes so perfect that "snarls" in the threads are
partly if not wholly prevented.
I carry out my invention by an arm or lever carrying the pin for the nosing bowl,
and I will call this arm the nosing arm, which is on a fulcrum pin secured in the
radial arm, and from the nosing arm another arm extends backwards (which I will
call the back arm) which is more or less at an angle to the nosing arm as
required.
When the radial arm comes into the position to bring the nosing bowl against

page_text: the "winding on chain" the back arm comes against a stud on an arm or lever on a
stud in the framing and as the radial arm continues its descent the nosing arm is
thus caused to partially rotate upon its fulcrum and act to draw more or less chain
as arranged, from the winding on drum at the time required.
The arm carrying the stud is on the side of or forms a part of the segment of a
ratchet wheel on a stud in the framing, and there is a single or double pawl on a
stud in the framing, that comes against the teeth of the segment of a ratchet so as
to retain this ratchet when moved, and prevent its arm carrying the stud from
moving when the back arm of the nosing arm comes against it.
At the commencement of a set of cops the stud arm is in its lowest position, and
as the cop builds, the stud arm is gradually lifted higher and higher so that the
back arm and thus the nosing arm will receive more and more motion on its fulcrum
as the
cop builds.
I prefer to lift the stud arm as the cops build by a stud adjustable in a slot
in an arm secured on the copping faller shaft, which arm. will thus change in
position as the cop builds.
The stud in the arm from the copping faller shaft in passing comes under a ledge
on the stud arm and thus lifts it at each time of passing until it is lifted high
enough to be retained in its higher position by the pawls of the segmental
ratchet.
Or the segmental ratchet may be partly rotated as the cops build, and thus the
stud arm may be gradually lifted higher and higher by a chain, one end of which is
attached to the periphery of the segmental ratchet and then passes over guide
pulleys, the other end being attached to the shaper rod, but I prefer to actuate the
stud arm by the arm from the copping faller.
Fig. 1 is a side elevation of so much of the radial arm of a self-acting mule and
connected parts as will be required to fully explain my invention.
A, is part of the framing of the headstock; b, the ordinary radial arm on its axis
at, the toothed segment connected with the radial arm by which it is actuated
by gearing with a pinion at 63.
a, is the guard for the toothed segment b².
c', is the nut part in the radial arm to which one end of the winding on chain c,
shown by dotted line is attached.
d, is the nosing arm, which has a slot d', in its end in which a pin or stud can be
adjusted and secured for a bowl 2, that is to coine against the winding on
chain c.
The nosing arm d, has a back arm d³, at any required angle to the nosing arm d,
both together forming one lever, on a fulerum stud d', in the radial arm b.
The back arm d³, may be separate from the nosing arm d, but secured to its boss
by a set screw or other means at any required angle to the nosing arm d.
This nosing arm d, is placed to come between the side of the radial arm b, and
the framing a.
e, is a pulley, partly toothed with ratchet teeth, it is upon a stud e¹, secured in
the framing.
From the front face of the ratchet, an arm e², extends, and on the front of this
arm there is an inclined projecting ledge e³, which at the end forms a stud or
projection e, this arm e², being the stud arm.
On a stud e, in the framing, there are one or more ratchet pawls e, side by side,
all coming against the teeth of the ratchet, one pawl (if there are two) a little
shorter than the other 30 as to divide a tooth, that is to say, if the ratchet moves to
the extent of half a tooth it will be retained by one or the other of the ratchet
pawls eº.
There is a tail part e, from one or both ratchet pawls e, by lifting which the
pawls can be taken clear of the teeth of the ratchet e, which will then allow the
stud arm e², to fall to its lowest position that is until a projection on the back of it
comes against the edge of the frame (a) or a stop from it in the framing.
f, represents the copping taller shaft, and it has an arm f', which at the boss

page_text: part is made in two halves so as to be readily secured to the copping faller
shaft f.
The lower end of the arm f, is slotted in order that a stud 2, may be adjusted
and secured in it. This stud f, projects on one side of the arm f, towards the
arm e, and comes under the inclined ledge e³, of the stud arm e, when the mule
carriage is passing towards the roller beam and thus lifts the stud arm e²,
slightly.
But it may have to pass several times before it lifts the arm e³, high enough so
as to be retained at the level to which it is lifted by the ratchet pawls, as the
ratchet e, may only be moved sufficiently for one half tooth after a number of
"stretches" or goings in and out of the carriage.
The copping faller f, is not shown in the drawing in the position it occupies when
the radial arın b, is in the position shown, but only in the position it occupies when
passing the stud arm ², and its inclination varies from that shown, as the cops
build.
When the radial arm b, is in about its vertical position (it is a little back from
the vertical position when the carriage is fully out) the nosing arm d, extends at
about a right angle to the radial arm b, and there is a pin or other stop d³ to
prevent the nosing arm d, from falling lower, but when the radial arm b, moves
forward when the carriage goes in, the bowl d², on the nosing arm comes against
the winding on chain c, and this lifts the arm d, until the back arm d³, comes
against the stud e, on the stud arm e², and then as the radial arm b, continues its
descent the nosing arm d, receives the movement on its fulcrum d', to act upon the
winding on chain c, to the extent and at the time required to obtain the perfect
winding of the yarn or threads
the cops.
upon
It will be noted that the arm, from the copping faller, is away and clear of
the stud arm e, and incline e³, when the carriage is going out and it has acted upon
the incline e³, and is clear of it when the back arm d³, is acting upon
stud e¹.
the
When the partial ratchet wheel e, is to be operated from the copping rail one end
of a chain or other suitable connection (indicated by dotted line 9) is attached to
its periphery and is then taken over guide pulleys g¹, and g², the other end being
attached to the shaper rod.
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 what I
claim is.
1. The combination of an arm or lever on a fulcrum carried upon the radial
arm (6) actuated by coming in contact with a stud or projection which is auto-
matically adjusted in position as the cop builds, by an arm from the copping faller
shaft, or a chain or connection from the shaper mechanism, substantially as herein-
before described and illustrated by the drawings.
2. The combination with the radial arm b, of a self-acting mule of a nosing
arm d; stud e', carried on an arm e, from a partial ratchet wheel e, retained by
one or more pawls e, the stud arm e', being operated by an arm, from the
copping faller shaft f, or by a chain or connection y, from the shaper, substantially
as and for the purpose herein before described and illustrated by the drawings.
