I RICHARD LEACH HOLT of 16 Westminster Street Oldham in the County of
Lancaster Mechanic do hereby declare the nature of this invention to be as follows:-
This invention relates to the construction of a simple self-acting "nosing motion"
for tightening the winding chain of a self-acting mule or twiner as the building up of
the nose of the cop proceeds.

To the quadrant arm" I fix a bracket which supports a hanging lever, at or near
the end of which is a pin or bowl resting against the winding chain.
To about the centre of this lever I attach one end of a chain the other end of which
is partly coiled round and fixed to a pulley carried on a bracket fixed on the side of
the quadrant.
To this pulley is cast on one side a ratchet wheel and to the other side is cast a cam
or snail. A second chain is partly coiled on and fastened to this cam or snail and
this chain is carried by guide pulleys and its other end is attached to a fixing on the
shaper rod.
As the building up of the cop proceeds the shaper rod is caused to move in the
ordinary manner and by the usual mechanism further from the quadrant thus
uncoiling the second named chain from the cam or snail above mentioned and turning
the latter partially round causes the pulley to wind on a portion of the first named
chain and thus cause the hanging lever to press the pin or bowl onto the winding
chain which will have the effect of shortening or tightening the same on the winding.

An Improved "Nosing Motion" for Selfacting Mules and Twiners.
I RICHARD LEACH HOLT of 11 Bartlemore Street, Albert Mount, formerly of
16 Westminster Street Oldham in the County of Lancaster Mechanic 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 the construction of a simple self acting "nosing motion"
for taking up the winding chain of a self acting mule or twiner during each stretch
as the building up of the cop proceeds, after the bottom of the cop is fully formed.
The nature of the said invention and the manner in which the same is to be carried
into practical effect will be readily understood on reference to the two sheets of
drawings hereunto annexed and the following explanation thereof.
Fig. 1 sheet 1 on the drawing is an elevation of so much of the winding motion of
a self acting mule as is necessary to illustrate my invention and Fig. 2 sheet 2 is a
similar view of a modification of the same.
dis part of the headstock framing, the quadrant, c the quadrant arm, d the screw
of the same, e the winding chain and the "shaper rod," the above are ordinary
parts.
To the quadrant arm c there is fixed a bracket which carries the fulcrum of a
hanging lever h, at or near the end of which is a pin or bowl, el resting against or
upon the ordinary winding chain e.
To about the centre of this lever, that is, at n¹ I attach. one end of a chain the
other end of which is partly coiled round and fixed to a cam or snail k carried on a
bracket fixed to the side of the quadrant.
·
To this cam or snail is cast or fixed a ratchet wheel 7 (see also detached view
Fig. 3 sheet 1) and to the same side or to the other side thereof is cast or fixed a
pulley m.
0
One end of a second chain n is partly coiled on and fastened to the pulley m and
this chain'n (passing in any required direction) is carried by guides or pulleys (one
on each side of the headstock) and its other end is attached to an adjustable fixing p.
secured by a set screw on the shaper rod . Or if preferred the chain i may be
fastened to the pulley m and the chain n. to the cam or snail k or both k. and m. may
be snails or cams set of course in reverse directions so that one may wind its chain on
as the other unwinds, and formed so that as the cop builds the chain will be wound
upon the cam snail or pulley at the desired speed. A segment wheel may also be
used in place of the entire ratchet wheel 1. I provide a guide plates and a finger t
to keep the chains and in place while the radial arm or quadrant is oscillating to
and fro.
་
As the building up of the cop proceeds the shaper rod g is caused to move in the
direction of the arrow (in the ordinary manner and by the usual mechanism) further
from the quadrant & thus to an equal extent uncoiling the chain a from the pulley m
and turning the latter partially round causing the cam or snail k. to wind on a portion

page_text: of the chain and the hanging lever to press the pin or bowl onto the winding
chain
e, more and more as the cop builds which will have the effect of shortening or
tightening the same and of giving more rotating motion to the winding drum. The
ratchet wheel attached to the pulley and snail is for the purpose of preventing the
same from running back and it is held by means of a catch on a fulcrum pin attached
to the bracket or fixing on the side of the quadrant b. the catch being acted upon by
a spring as shown. This catch thus also takes the strain that comes upon the chain i.
It will be seen that when the radial arm is moving outwards with the mule carriage
the chain is tightened, and it is tightened to its full extent when the radial arm has
oscillated backwards to its greatest extent and it is at this moment that the ratchet
wheel is turned but it is only turned one tooth at a time when the shaper has moved
to the extent of one tooth of the ratchet, and it will thus be seen that when any strain
does come upon the chain it is when the ratchet is perfectly free to turn and at a
time when there is no strain upon it by the chain i. which strain upon the latter chain
only comes upon the ratchet pawl when the carriage is moving in to wind the thread
upon the spindles.
According to the modification shewn at Fig. 2 Sheet 2 I sometimes mount the
pulley M ratchet wheel and cam or snail on a bracket attached to any
conveniently situated fixed part of the mule framing or to the ground, but in this case
as they do not move to and fro with the quadrant I fix to the latter a pin or projection b¹
which as the quadrant oscillates presses on to the chainn and and when the chain
is tightened by the copping motion uncoils it from the pulley m and by turning the
latter partially round causes the cam k to wind on a portion of the chain i.
The chain is in a plane nearer to the quadrant than the chain i, and the projecting.
pin bis long enough to catch upon the chain but is short enough to pass the chain i.
without touching it.
It will thus be seen that the pin acts to tighten the chain n to its greatest extent
when the radial arm is making its back oscillation as before explained in reference to
fig. 1 so that the ratchet is only moved when not subjected to strain from the chain i.
At the commencement of a fresh set of cops the ratchet wheel in each modification
is turned back to a point fixed upon for its position at the commencement of each
fresh set of cops.
I wish it to be understood that the winding on chain according to my invention is
attached to the ordinary cylindrical winding on drum, and that its action is to cause
such drum to rotate more rapidly at the time the yarn is winding on to the spindles
at the nose" part of the cop by drawing off more chain from the winding on drum
than would be consequent upon the mere motion derived from the going in of the mule
carriage if a nosing motion were not in operation.
:
I wish this to be understood because there are automatic nosing motions which do
not shorten or take up the winding on chain during each "stretch"
as by my
invention, but which act by gradually, as the cop builds, winding up and drawing off
a portion of the chain from the winding on drum so as to bring the operative part of
the chain more and more upon a scroll of less diameter than the cylindrical part
formed upon one end of the winding on drum, consequently the chain unwound from
the scroll part gives increased rotation to the winding on drum.
My invention is applicable, to mules which have this compound scroll and cylindrical
winding on drum, but when applied to such winding drums the winding on chain
does not come upon the scroll part of the drum but works entirely upon the
cylindrical part of it which thus acts only in the case of my invention as a simple
cylindrical winding on drum.
In some cases the chain is or may be attached to or connected directly with the
winding on chain e at about one foot more or less from the point of its attachment
with the nut of the radial arm, thus dispensing with the lever , but I prefer to use
the said lever has hereinbefore described as the best and most satisfactory arrangement
giving the least trouble to the "Minders."
I am aware that levers have been proposed jointed on the radial arm carrying a
pin or bowl to act upon the winding on chain and that it has also been proposed to

page_text: automatically regulate the winding on by chains or connections with the copping rail
or its mechanism which arrangements as hitherto proposed are objectionable as in
such cases, where levers acting upon the winding chain are used, the strain upon
the winding on chain when operating has been thrown upon or partly thrown upon
the copping rail or shaper mechanism.
By my invention as above explained, no objectionable strain whatever is put upon
the copping rail or shaper mechanism and thus its proper action is not affected in
the least.
The mechanism is also perfectly automatic and does not require any adjustment
when changing
"counts" apart from the change in the copping motion for that
purpose.
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 chain n or its equivalent connected with the shaper
mechanism and with the pulley cam or snail or their equivalents a ratchet and pawl or
their equivalents and a chain i substantially as and for the purpose hereinbefore
described and illustrated by the drawings.
2. The combination of a chain n or its equivalent connected with the shaper
mechanism and with the pulley cam or snail or their equivalents a ratchet and pawl or
their equivalents a chain and lever / substantially as and for the
herein before
described and illustrated by the drawings.
purpose
3. The arrangement and combination of the mechanism where the winding on
chain operates upon an ordinary cylindrical winding on drum so that the strain of
the winding on chain will come upon the ratchet and pawl or its equivalent and so
that the connection going to the copping rail will act to turn the ratchet when the
quadrant is going out substantially as hereinbefore described and illustrated by the
drawings.
4. The combinations and arrangements of mechanism substantially as hereinbefore
described and illustrated by Figs. 1 and 3 and figs. 2 and 3 of the drawings.
