JOHN SUTHERS, of Clarence Mill, Oldham, in the County of Lancaster, Cotton
Spinner, and CHARLES WILD, of the same Place, Overlooker. "IMPROVEMENTS IN
SELFACTING MULES OR TWINERS."
Our Invention refers to mechanism for acting upon the winding-on mechanism
of selfacting mules or twiners in such manner as to modify the winding-on of the
yarn or thread to suit the diminishing size of the spindles, as the cops increase in
size, by automatic means, such improved arrangement being termed "a selfacting
nosing motion."
In the ordinary selfacting mules and twiners there is what is termed a quadrant
and radial arm, which carries a screw that screws through a nut that is made to
travel up the screw of the radial arm while the bottom of the cop is being formed,
and to this nut one end of the winding-on chain is attached, the other end being
secured to the winding-on drum.
Our Invention consists in mounting a grooved pulley on the nut carried by the
screw of the radial arm, and causing the chain from the winding-on "scroll" to
pass over this nut, then down the radial arm, passing and being confined close to
the axis of the radial arm by a pulley on a bracket attached to the framing or
floor, then the end of the chain is secured to a bracket or stand secured to the floor
or framing.
On an arm attached to the shaper rail there is a pulley, which moves with the
shaper," and this pulley, when the bottom of the cop has been formed, comes

page_text: against the chain between the bracket, to which it is secured, and the axis of the
radial arm, and causes it to bend or take a loop form, and this takes up the chain
as the cop binds to the required extent, and modifies the winding-on as the chain
is withdrawn from, and thus acts upon a smaller part of the winding-on "scroll,"
to which it is attached.
Instead of an arm secured to or connected with the copping rail there is or may
be a bell crank or other lever on a fulcrum fixed on the floor or framing, and a
shaper slot formed in the copping rail acts upon the end of one arm of the bell
crank lever to move it to act upon the .chain as required; or the lever has its
fulcrum on the shaper rail, and is acted upon by a cam or cam slot secured to the
floor or framing.
When the cop begins to be formed on the spindles the pulley on the nut of the
screw is near the axis of the radial arm, and this pulley gradually ascends the
screw as the bottom of the cop is being formed, and ceases its ascent when the
bottom is forined, then the pulley in connection with the copping rail arrives in
contact with the winding-on chain, and continues to act upon it until the cops are
completed.

"IMPROVEMENTS IN
SELFACTING MULES OR TWINERS."
Our Invention refers to mechanism for acting upon the winding on mechanism
of "selfacting mules or twiners" in such manner as to modify the winding on of the
yarn or thread to suit the diminishing size of the spindles as the cops increase in
size by automatic means, such improved arrangements being termed a selfacting
nosing motion,
In the ordinary selfacting mules and twiners there is what is termed a quadrant
and radial arm, which carries a screw that screws through a nut, which is made to
travel up the screw of the radial arm while the bottom of the cop is being formed,
and to this nut one end of the winding on chain is attached, the other end being
secured to the winding on drum.
Our Invention consists in mounting a grooved pulley on the nut carried by or
connected with the screw of the radial arm, and causing the chain from the winding
on "scroll drum" to pass over the pulley on this nut, then down the radial arm,
passing close to the axis or partly round a pulley on the axis of the radial arm.
and it is or may be confined to the axis of the radial arm by a pulley on a bracket
attached to the framing or floor; then the end of the chain is attached to a bracket
or stand secured to the floor or framing, or to a slide, lever, or pulley, or other
suitable arrangement.
"
On an arm attached to the shaper plate or to a nut on the shaper screw there is
a pulley on a stud, which moves with the shaper" plate or the nut on the shaper
screw, and this pulley, when the bottom of the cop has been formed, comes against
the chain between the bracket to which it is secured and the axis of the radial
arm, and causes it to bend or take a loop form, and this takes up the chain as
the cop builds to the required extent, and modifies the winding on as the chain is
withdrawn from, and thus acts upon a smaller part of the winding on "scroll," to
which its end is attached.
Instead of an arm secured to or connected with the copping plate or with the
nut of the screw there is or may be a bell crank lever or other lever on a fulcrum
fixed on the floor or framing, and a cam slot formed in the copping plate acts upon the
end of one arm of the bell crank lever to move it, so that the bowl in the other arın
will act upon the chain as required; or the lever has its fulcrum on the side of the
shaper plate or on a part from it, and is acted upon so as to press upon the chain
by a cam or cam slot secured to the floor or framing.
Or the end of the chain is or may be attached to a slide lever, quadrant, scroll,
or pulley, and acted upon by connection with the screw nut of the "shaper," or by
being geared with the screw of the shaper or its nut, or from connected mechanism.
receiving motion at the same time as the shaper.
When the cop begins to be formed on the spindles the pulley on the nut of the
screw is near the axis of the radial arm, and this pulley gradually ascends the
screw as the bottom of the cop is being formed, and ceases its ascent when the
bottom is forined, then the pulley in connection with the copping plate or screw
arrives in contact with the winding on chain and acts upon it, or the mechanism
with which the end of the chain is connected acts upon the winding on chain, and
continues to act upon it until the cops are completed.
Fig. 1 is a side sectional elevation of so much of a selfacting mule or twiner as
will be necessary for explaining our Invention.
a, part of framing; b represents the drawing rollers; c, spindles in carriage d,
which moves to and fro on the wheel that run on the rails represented by the

page_text: line d; e, drum for driving the spindles; f, winding on "scroll drum"; g, radial
arm; h, part of the shaper plate; i, shaper screw; ¹, its nut; 22, ratchet, by which
shaper screw is turned by a pawl on an arm actuated by being connected by a
chain with the radial arın.
"
All the parts above referred to by letters are ordinary and well known.
Upon the sliding nut on the screw g* in the radial arm (g) a pulley g' is mounted,
and the winding on chain 1 (one end of which is attached to the "scroll drum
in the ordinary manner) is passed over the pulley g¹ of the radial arm, then
descends to the axis of the radial arm and passes it, or a pulley at or near the
axis of the radial arm, then over one or two pulleys (f² and f³) or curved surfaces,
and then is attached to a bar f sliding in a bracket secured to the framing.
This
slide bar (*) has a descending projection that comes in front of the nut (¹) on the
shaper screw (i).
The end of the slide bar (f) can move back when the shaper screw i is turned
back to begin a fresh set of cops until it comes against a stop on the framing, and
the nut (i) of the shaper screw comes in contact with the projection of the slide
bar when the shaper has arrived in that position where the bottom of the cop is
fully formed.
Fig. 2 illustrates another modification of our Invention for connecting the end
of the winding on chain f' with the copping rail motion.
A spur wheel is secured on the shaper screw (i), which gears with a wheel j
on the end of a short shaft (¹) having bearings in a bracket. The other end of
this short shaft has a worm 2 upon it that gears with a worin wheel j³ on a stud
secured in a part of the bracket for the short shaft (j'), which bracket is attached
to the framing.
Upon the same stud there is a pulley k, to which the end of a winding on chain
(¹) is attached.
The pulley k has a pin or stud in its side (not shown), which comes against a
stop on the bracket when the winding on chain is at its greatest length at the
commencement of a set of cops.
The worm wheel (3) moves to and fro with the shaper screw (i), and it has a
pin or stud in its side (not shown), which may be adjustable in a slot if desired,
and this pin or stud comes against the one in the pulley () when the bottom of
the cop is fully formed, then its continued motion with the shaper screw causes the
pulley to shorten or take up the winding on chain as the cop builds.
The pulley k with this arrangement may be of scroll or partial scroll form if required,
and may be attached to and made to oscillate to and fro with the worm wheel if
required, in which case the end of the chain (f¹) is attached to the pulley or scroll
or partial scroll, and arranged so that during that part of the movement, while the
bottom of the cop is being formed, but very little, if any chain, will be taken up,
but after which time the pulley or scroll will take up the desired amount.
Fig. 3 illustrates another modification for carrying out our Invention.
Z is a lever formed by a segment of a pulley on one side and an arm on the other
side of its fulcrum (), which is mounted upon a stud in the framing.
The winding on chain (1) is attached to the pulley part of the lever (2), and
there is a stop on the frame to limit its back movement when the shaper screw (i)
is turned back to commence a fresh set of cops. A stud from the nut (i) of the
shaper screw comes against the arm of the lever (l) when the bottom of the cop is
fully formed, and this causes the segmental pulley part of the lever (l) to take up
or shorten the winding on chain as required.
It will be obvious to any mechanic that a variety of arrangements of mechanism
may be used in place of those illustrated and hereinbefore described for connecting
the winding on chain with the shaper mechanism without departing from the
main features of our Invention, in fact the winding on chain arranged according
to our Invention may be shortened by a screw or other mechanism independent of
the shaper screw, but not so simply as by the arrangements illustrated and described
by us, and with the disadvantage that there would be two arrangements of

page_text: mechanism to adjust at the commencement of each set of cops, whereas by those
arrangements of our Invention above described and illustrated, which we prefer
and recommend, the shortening motion is simultaneously adjusted with, and when
the shaper screw is turned back at the commencement of each set of cops.
We have now particularly described the nature of our Invention and the mode
of carrying the same into effect, and claim as our Invention, -
-
Firstly. The arrangement of the winding on chain of selfacting mules or twiners,
so that it passes over a pulley or surface on or connected with the nut of the radial
arm and then passes, and is attached to mechanism so as to be connected or in
gear with or be acted upon by the shaper screw or shaper mechanism, or to
mechanism for shortening or winding up the chain (f³) as the cop builds, sub-
stantially as herein before described, and illustrated by the accompanying Drawings.
Secondly. The several combinations and arrangements of mechanism for regu-
lating the "winding on in inules or twiners, substantially as hereinbefore described,
and illustrated by Figs. 1, 2, and 3 of the Drawings.

eight hundred and seventy nine.
