We BENJAMIN ALFRED DOBSON, Machinist, and ROBERT HARDMAN, foreman,
both of Kay Street Works, Bolton, in the County of Lancaster, do hereby declare
the nature of said Invention for IMPROVEMENTS IN NOSING MOTION FOR WINDING
ON MOTION OF SELF ACTING MULES AND TWINERS, to be as follows:-
Our invention relates to what are generally known as nosing motions and
consists in improving the nose of cops wound on the spindles of self acting mules
and twiners by a novel method of giving additional winding at the extreme end of
the cone of the cop in proportion as the spindle diminishes in diameter.
Our invention first of all consists in applying a second chain, fastened at a
certain distance from the quadrant nut on to the quadrant chain, so that when the
quadrant arm is being depressed by the quadrant rack to give the proportion of
winding, the second chain comes into action and by deflecting the ordinary winding
chain increases the effect upon the winding.drum in the proportion required..
Our invention further consists in regulating this proportion either by the shaper
or the copping faller.
:―
We will describe the motion as applied to and regulated by the copping faller :-
On the quadrant slide is affixed a bracket on a stud, on which works a lever, this
lever has at, its extremity a tumbler incline and next to the quadrant slide a
tumbler catch which engages with a fine toothed rack affixed to the quadrant slide.
There is also near the foot of the quadrant slide a bracket having a loose grooved
pulley, and the extra chain which goes round this pulley and which we have above
described is fastened to the lever already mentioned, generally speaking, between
the tumbler incline and the tumbler catch, and is then fastened at the other end to
the ordinary winding chain.
On the copping faller, there is a lever with a slot or number of holes in it, for
regulation, and a bar attached to it by a stud, and secured at its lower end in a
slide, and on this bar is placed a sliding bracket with a bowl or stud which can be
regulated at any height, up, or down.
The nosing motion is not required to act until the bottom of the cop is finished ;
when the mule carriage is coming out the copping faller is always in the same
position, which would mean that the bowl spoken of, as being on the bracket of
the bar would be at its highest position. The motion is therefore set so that the
bowl coming out, will lift the tumbler incline and pass underneath it, the incline

page_text: resuming its place by spring or gravity; when the copping filler is depressed, the
distance necessary to connect it with the shaper, the bowl passes the incline without
touching it, until the bottom is finished, then it commences to catch the incline in
the inward run of the carriage.
According to the rise in the copping faller in proportion to the rise and building
of the cop, the motion takes more and more of. the toothed rack so that the lever
is raised from its original position. As it is raised from its original position, it of
course moves the chain attached to it, and when the quadrant slide is following the
.carriage in the run in, and is depressed, this chain gradually comes more and more
into action and deflecting more and more the winding chain, gives assistance to the
winding spindles at the thin portion of the blade of the spindle, which is, when it
is most required.
We also employ between the lever and the end of the additional chain, a strong
close coiled spiral spring with the view of avoiding any jarring. We prefer to use
a spring made according to the Specification to Letters Patent granted to Mr George
Knowles, of Bolton, No 1410 A.D. 1870.
We have described the motion as applied to and regulated from the copping
faller, but it will be readily understood that the same motion can also be actuated
from the shaper.
The cop having been finished and the mule doffed when it is necessary to wind
down the chain nut on the quadrant slide to begin a fresh set of cops, there is an
arrangement on the nut which works in the quadrant slide and holds the end of
the winding chain to take the tumbler catch out of gear with the rack, so that it
may be certain to be always in the correct position for starting at the beginning of
the cop.
°
Another advantage is, that the motion is perfectly automatic in the sense, that
if it is put out of action wilfully by any person, the next draw of the carriage
places it in its proper position again with the greatest exactitude. It is obvious
that the motion being worked from the faller, or shaper, no change is required for
any alteration of counts that may be required to be spun.
Should we require to increase the amount of chain taken up we can double the
effect by fastening one end of the tightening chain to the bottom bracket and
.passing it round a carrier pulley on the arm lever thus gaining the action of a
loose block pulley." The spring may be placed at any part of the tightening
chain.

acting Mules and Twiners.
We BENJAMIN ALFRED DOBSON, Machinist, and ROBERT HARDMAN, Foreman,
both of Kay Street Works, Bolton in the County of Lancaster do hereby declare
the nature of said Invention for IMPROVEMENTS IN NOSING MOTION FOR WINDING
ON MOTION OF SELF-ACTING MULES AND TWINERS, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement:―
:
Our invention relates to what are generally known as nosing motions and
consists in improving the nose of cops wound on the spindles of self-acting mules
and twiners by a novel method of giving additional winding at the extreme end of
the cone of the cop in proportion as the spindle diminishes in diameter.
Our invention first of all consists in applying a second chain, fastened at a
certain distance from the quadrant nut on to the quadrant chain, so that, when the
quadrant arm is being depressed by the quadrant rack to give the proportion of
winding, the second chain comes into action, and by deflecting the ordinary
winding chain increases the effect upon the winding drum in the proportion
required.
Our invention further consists in regulating this proportion either by the shaper
or the copping faller.
We will describe the motion as applied to and regulated by the copping faller.
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 a self-acting mule to which our improved nosing
motion is applied, the carriage and other parts being shown in the positions they
occupy at the end of the outward run. Fig. 2 is a similar view the carriage being
shown at the end of the inward run and Fig. 3 is a plan of Fig. 2.
On the quadrant slide a is fixed a bracket b with a stud b' on which works a
lever c which has a tumbler incline c' and a tumbler catch & which is pivoted
at to the lever c and held in gear by means of a spring c³ with a fine toothed
rack e formed on the bracket b. There is also mounted loosely on the bracket b
near the foot of the quadrant slide a, a grooved pulley f round which passes the
extra chain which is fastened at one end to the ordinary winding chain k and is
fastened at the other end to the lever c generally speaking between the tumbler
incline c and the tumbler catch d; the Drawing shows the chain 7 secured by a
spring g¹ and adjusting screw g² to the end of the lever c. The spring g¹ which
may be placed at any part of the chain 9, is a strong closely coiled spiral spring
with the view of preventing any jarring and we prefer to use a spring made
according to the Specification to Letters Patent granted to Mr George Knowles, of
Bolton, No 1410 of A.D. 1876. On the copping faller i is fixed a lever ; provided
with a number of holes (or a slot) for regulation or adjustment; a bar k is secured
at one end to the leverj by a stud and the lower end is held in a slide secured
to the square of the carriage m and on this bar k is placed a sliding bracket or
adjustable finger n with a bowl or stud o which can be regulated at any height
and angle up or down by means of holes in the bark and adjustable finger n.

The nosing motion is not required to act until the bottom of the cop is finished:
when the mule carriage m is coming out, the copping faller i is always in the same
position, that is to say, the bowl or stud o on the adjustable finger n would be at
its highest position. The motion is therefore set so that the stud o on coming out
will lift the tumbler incline c' and pass underneath it, the incline c¹ being returned
to its normal place by a spring or by gravity. When the copping faller is
sufficiently depressed the stud o passes the incline c¹ without touching it until the
bottom of the cop is finished, then the stud o commences to catch the incline c¹ in
the inward run of the carriage m: according to the rise of the copping faller i in
proportion to the rise and building of the cop the catch d takes more and more of
the toothed rack e so that the lever c is raised from its original position thereby
moving the extra chain g attached to it and when the quadrant slide a is following
the carriage m in the run in, and is depressed, the chain g gradually comes more
and more into action, and deflecting more and more the ordinary winding chain /
gives assistance. to the winding spindles at the thin portion of the blade of the
spindle, which is when assistance is most required.
The cop, having been finished and the mule doffed when it is necessary to wind
down the chain 'nut p on the quadrant slide a, to begin a fresh set of cops there is
an arrangement on the nut p which as it is screwed down in the quadrant slide
moves the tumbler catch d out of gear with the rack e and allows the moving
parts to return to their normal positions, so that the catch may be certain to be
always in the correct position for starting at the beginning of the cop.
The motion is perfectly automatic in the sense that if it is wilfully put out of
action, the next draw of the carriage returns it to its proper position by the stud o
raising the tumbler catch d. It is obvious that the motion being worked from the
faller (or shaper) no change is required for any alteration of counts that may be
required to be spun.
•
If required to increase the amount of chain to be taken up we can double the
effect by fastening one end of the tightening chain g to the bracket band passing
it round a carrier pulley on the lever c, thus gaining the action of a "loose block
pulley."
We have shown and described the motion as applied to and regulated from the
copping faller but it will be readily understood that the same motion.can also be
actuated from the shaper in a similar manner.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, we declare that
what we claim is
1. The use and application of an extra chain or its equivalent in combination
with the ordinary chain of the winding on motion of a self-acting mule or twiner,
substantially in the manner and for the purposes herein set forth.
2. The method of and means for regulating either from the copping faller or
the shaper the amount of additional winding given at the extreme end of the cop
in proportion as the spindle diminishes in diameter, substantially as heroin set
forth.
