EDWARD WHALLEY, of the City of Manchester, in the County of Lancaster,
Machinist, and JOHN HOWARD STOTT, of Rochdale, in the said County, Engineer
and Machine Maker. "IMPROVEMENTS IN MACHINERY FOR DOUBLING AND
WINDING, AND DOUBLING AND TWISTING YARNS OR THREADS."
Firstly. Our Invention relates to mechanism for doubling and winding, and con-
sists in an improved combination and arrangement of mechanism.
The mechanism is arranged in a frame containing any convenient number of
spindles, but it will only be necessary to describe the mechanism connected with one
spindle or bobbin.
The bobbin upon which the threads are wound is placed with its axis on a vertical
spindle and with its end resting upon a cup or disc fast on the spindle, the bobbin
being thus driven by friction. The doubled threads pass from the detector
mechanisin (to be hereinafter described) and pass round a small drum mounted
with its axis in a horizontal position on a stud or on a short shaft having bearings
in a bracket on the framing, and then pass on to the bobbin on to which the
threads are to be wound.
There is a small grooved pulley fast on the short shaft for the small drum or
connected with it for a band, which works on a double grooved pulley loose on a
shaft, passing from end to end of the frame, and the same band also works on the
warf of the spindle driving the bobbin on to which the threads are to be wound,
consequently, both drum and spindle will be stopped and started simultaneously
when the double grooved pulley is thrown out of or in to gear.

page_text: It will be seen that as the small drum is driven at a uniform speed it will
deliver the threads to be wound on the bobbin, also at the same uniform speed
the bobbin on the spindle slipping as the diameter increases by the thread wound
upon it.
The said double grooved pulley has a clutch groove in its boss and ratchet clutch
teeth which can gear with corresponding teeth on the end of a ribbed boss fast on
the said shaft passing from end to end of the machine.
There is a lever with its fulcrum in a vertical position on a stud in the bracket
secured to the framing, and this lever has two arms, one for the clutch groove in
the double grooved pulley, and the other to act as a stop, and there is also a vertical
branch from the lever to be used as a handle to move it when the winding is to
commence.
There is also a spring, one end connected with a stud on the bracket, and the
other with the clutch lover, the force of which spring acts to pull the clutch out of
gear and stop the winding.
On the bracket there aro bearings for a T formed piece, which is arranged to
slide horizontally in a line at a right angle to the said shaft, passing lengthway
of the machine, and this T formed slide has at one end a part with a flat and
bevelled side, against which the end of the stop arm of the said clutch lever comes,
and when against the flat part the clutch is in gear, but when the T slide moves
the stop end of the lever comes upon the bevelled part and the clutch is thrown
out of gear and the T slide is moved further (to clear the "detectors") by the
force of the spring acting upon the clutch lever. There is also a spring to act upon
the formed slide of sufficient force to draw it back when the lever is moved to
start the winding.
The cross part of the T slide is formed to carry the detector mechanism, which
consists of a lever made of wire (one lever for each thread), which levers are upon
a rod or wire carried by the T slide.
Each wire lever has a drop wire hung upon it that can slide vertically up and
down freely in guide holes formed in the cross end of the slide, which in working
position is just over the said ribbed boss on the said rotating shaft, passing from end
to end of the machine.
The threads being doubled pass in an ordinary manner over guides and rods, and
each thread through an eye in one of the wire levers, and as long as the threads are
present and in tension, the wire levers and drop wires are held up; but when one or
more threads break or are absent, their levers and drop wires fall, and the lower
ends of the wires come in contact with the said rotating ribbed boss, which thus
moves the slide and stops the winding.
The threads are guided while being wound upon the bobbin by any ordinary
traverse arrangements.
Our improved combination and arrangement of detector and stop mechanism is
also applicable to doubling and winding where the bobbin on which the threads are
to be wound is placed, with its axis in a horizontal position, with its cylindrical
surface resting upon a drum by which it is rotated.
Secondly. Our Invention relates to doubling and twisting where the threads are
doubled and wound on to a bobbin and twisted at the same time, and consists in
combining the mechanism described under the first head of our Invention, with a
spindle arranged for twisting by a "flyer" or "ring and traveller."
The spindle is driven by the same band and double grooved pulley as is used for
driving the small drum and winding spindle, but the spindle and bobbin and other
parts substituted for the winding spindle are arranged similar to those used in
spinning machines for spinning by "flyers" or "rings and travellers."

by the said Edward Whalley and John Howard Stott in the Great Seal
Patent Office on the 28th April 1881.

Machinist, and JOHN HOWARD STOTT, of Rochdale, in the said County, Engineer.
and Machine Maker. "IMPROVEMENTS IN MACHINERY FOR DOUBLING AND
WINDING, AND DOUBLING AND TWISTING YARNS OR THREADS."
Firstly. Our Invention relates to nicchanism for doubling, and winding, and
consists in an improved combination and arrangement of mechanism.
The mechenism is arranged in a frame containing any convenient number of
spindles, but it will only be necessary to describe the mechanisın connected with
one spindle or bobbin.
The bobbin upon which the threads are wound is placed with its axis on a
vertical spindle and with its end resting upon a cup or disc fast on the spindle, the
bobbin being thus driven by friction.
The doubled threads pass from the detector mechanism (to be hereinafter
described) and pass round a small drum mounted with its axis in a horizontal
position on a stud or on a short shaft having bearings in a bracket on the framing,
and then pass on to the bobbin on to which the threads are to be wound.
There is a small grooved pulley fast on the short shaft for the small drum, or
connected with it for a band which works on a double grooved pulley loose on a
shaft, passing from end to end of the frame, and the same band also works on tho
warf of the spindle driving the bobbin on to which the threads are to be wound,
consequently, both drum and spindle will be stopped and started simultaneously
when the double grooved pulley is thrown out of or in to gear.
It will be seen that as the small drum is driven at a uniform speed it will deliver
the threads to be wound on the bobbin also at the same uniform speed, the
bobbin on the spindle slipping as the diameter increases by the thread wound upon it.
The said double grooved pulley has a clutch groove in its boss and ratchet clutch
teeth, which can gear with corresponding teeth on the end of a ribbed boss fast on
the said shaft passing from end to end of the machine.
There is a lever with its fulcrum in a vertical position on a stud in the bracket
secured to the framing, and this lever has two arms, one for the clutch groove in
the double grooved pulley, and the other to act as a stop, and there is also a vertical
branch from a horizontal arm of the lever to be used as a handle to move it when
the winding is to commence.
There is also a spring, one end connected with a stud on the bracket, and the
other with the clutch lever, the force of which spring acts to pull the clutch out of
gear and stop the winding. On the bracket there are bearings for a T formed
piece, which is arranged to slide horizontally in a line at a right angle to the said
shaft, passing lengthway of the machine, and this T formed slide has at one end a
part with a flat and bevelled side, against which the end of the stop arm of the said
clutch lever comes, and when against the flat part the clutch is in gear; but when
the slide moves, the stop end of the lever comes upon the bevelled part and the
clutch is thrown out of gear and the T slide is moved further (to clear the
detectors) by the force of the spring acting upon the clutch lever.
.There is also a spring to act upon the T formed slide of sufficient force to draw
it back when the lever is moved to start the winding.
The cross part of the T slide is formed to carry the detector mechanism, which
consists of a lever made of wire (one lever for each thread) which levers are upon
a rod or wire carried by the T slide.
Each wire lever has a drop wire hung upon it that can slide vertically up and
down freely in guide holes formed in the cross end of the T slide, which in working
position is just over the said ribbed boss on the said rotating shaft, passing from
end to end of the machine.

ends of the wires come in contact with the said rotating ribbed boss, which thus
moves the T slide and stops the winding.
The threads are guided while being wound upon the bobbin by any ordinary
traverse arrangements.
Our improved combination and arrangement of detector and stop mechanism is
also applicable to doubling and winding, where the bobbin on which the threads
are to be wound is placed with its axis in a horizontal position with its cylindrical

Secondly. Our Invention relates to doubling and twisting where the threads are
"doubled" and wound on to a bobbin and twisted at the same time, and consists in
combining the mechanism described under the first head of our Invention, with a
spindle arranged for twisting by a "flyer" or "ring" and "traveller."
The spindle is driven by the same band and double grooved pulley as is used for
driving the small drum and winding spindle, or the small drum is driven from a
shaft separately, but the spindle and bobbin and other parts substituted for the
winding spindle are arranged in a similar manner to those used in spinning
machines for spinning by "flyers" or "rings and travellers."

Fig. 8 is an end, and Fig. 9 a back elevation, and Fig. 10 a plan of a doubling
and twisting machine according to our Invention.
The term "doubling" refers to the union of two or more threads.
We shall first describle the manner of carrying out the first part of our
Invention.
Our Invention is applicable to either single or double machines, that is, to
machines having sets of doubling and winding apparatus on one or both sides of
the frame.
In Fig. 1 we have illustrated the mechanism as applied to a double sided machine,
but have only shown one spindle, and the mechanism connected with it on one
side of the machine.
a is part of the end framing of a double sided winding and doubling machine;
a', the beams or rails for tho winding spindles; b, c, the vertical sliding rod for
carrying the traverse rails c', which rod is actuated by ordinary mechanism; a² is
a beam passing from end to end of the frame, and there is one beam (a²) on each
side of a double sided machine.
d is a shaft, also passing from end to end of the machine, being carried in
suitable bearings and rotated in any convenient manner in the direction pointed
by the arrow; there is one of these shafts for each side of a double sided
machine.
For each spindle b in the machine there is a bracket e secured to the beam a²,
which bracket has upright bearings for a T formed slide, which can slide hori-
zontally to and fro, and at a right angle to the shaft d.
Figs. 3 and 4 show this T slide detached.
The cross part f¹ of the slide is formed by two ribs which have holes drilled
through them for drop wires f2, the eye of each drop wire passing upon wire
detector levers f" which are formed by curling the wire, as shown, to oscillate freely
on a fulcrum rod f* in bearings on the T slide.

page_text: There is a projection f³ from the boss part of each detector lever f³, which will
come against the cross part (f') of the T slide when the wire levers (f³) have
lifted high enough.
When the drop wires (f) are in the position shown by Fig. 1 their lower ends
are clear of the ribs upon the boss d' secured upon the shaft d; but when these
wires drop in the absence of a thread, the lower end of the wire comes in the way
of the ribs on the boss d', which moves the T slide endways.
The end of the boss d¹ is toothed to form one part of a clutch box, and the
other part is formed on the boss of a double grooved pulley d².
There is a groove in the boss of the pulley d² for the pin in a lever 9. which
has its fulcrum g² on a stud secured in a projection upon the bracket e.
The lever g is formed, as shown in Figs. 1 and 2, and as shown detached by
Figs. 5 and 6. g' is the pin for the clutch; g³ is an arm for a stop; g³, the arm
for the handle, and g³ the arm for the spring.
The projection g6 from the arm rests against a part f* secured to the end of the
T slide (f) as shown.
While the threads are all present the projection 9 rests upon the step, but when
the slide fis moved endways by the rotating ribbed boss d, the projection gⓇ comes
upon the incline on the part fx and the force of a spring h (one end of which is
attached to the projection from the lever g* and the other end to a projection e¹
from the bracket e) pulls the lever to one side, and thus throws the clutch pulley d'
out of gear, and also pushes the slide ƒ further endways to take the drop wires f*
clear of the rotating ribbed boss d².
The handle g is for forcing the lever back when the winding is to begin again,
and there is a small spring e² which has force enough to move back the T slide (ƒ)
until a pin fo in its side comes against one of the bearings of the bracket e.
The small spring e is attached to a pin in the T slide and to a hook in the
bearing of the bracket for the T slide.
Upon the beam a² there is a bracket i secured, which forms the bearing of a
short shaft i, on one end of which a small drum is secured, and on the other
end a grooved pulley ; the bracket also carries a wire guide or curl ¿ª.
The threads being wound and "doubled" are drawn from cops or bobbins
arranged in any ordinary creel; each thread passes through the slit in an ordinary
guide plate over a pad, and then over a rod j² through the curl of one of the
detector wire levers fs, over another rod j³ (these rods pass from end to end of the
frame), and then unite at the wire curl, pass round the drum to the wire
curl c or plate in the traverse rod c', and on to the bobbin x.
The same driving band k drives both the drum and spindle b, and passes, say,
from the top side of the outside groove of the double grooved pulley d³ round the
pulley back to the under side, but to the inside groove of the pulley d², and
passes round and from the top side of that groove to the warf on the spindle b,
round it, and back to the underside of the outside groove of the pulley d², uniting
with the end supposed to begin at the top side of the outer groove of that
pulley.
20
It will be seen that when the double grooved pulley d² is thrown out of gear
with the driving boss d¹ that both the drum and bobbin a will be stopped, and
when the pulley d² is thrown into gear they will be started again.
Fig. 7 illustrates a modification in which our Invention is applied to stop the
spindle of an ordinary winding frame a.
The spindle b is arranged and driven by a band in the ordinary manner, but on
the cup or disc for carrying and driving the bobbin x (only partly represented),
there are one, two, or more pins or projections x².
On a bracket i secured to the spindle rail a' there is a stud to carry the
fulcrum g' of a bell crank lever g.
One arm of this lever is vertical, and its end when moved outwards will come
in the way of the pins and arrest the motion of the spindle; and when this takes
place, the band driving it will slip upon the warf.

page_text: The other arm of the lever g has a projection ge from its side, which rests upon
a step on the part f* secured to the end of the T slide f.
The other part of this arm of the lever g forms a handle g' to lift the lever into
the position in which it is shown.
From the bracket i there is a projection i' for a stud for one end of a spring h,
the other end of which is secured to the upright arm of the bell crank lever g, the
force of the spring thus acting to press the horizontal arm of the lever downwards
when the T slide f is moved backwards, and this pressure of the spring causes the
edge of the projection go from the lever to press upon the incline of the part f*
secured to the T slide, and force it back to bring the ends of the drop wires f
clear of the rotating ribbed boss d'.
In the modification of our Invention, illustrated by Fig. 7, the mechanism is the
same as that illustrated by Figs. 1 and 2, except that only the rotating shaft d,
ribbed boss d¹, T slide f, its detector wires, and the rods j and 73, and small
spring is required in addition to the parts shown in Fig. 7.
Our improvements are also applicable to doubling and winding frames where
each bobbin is placed in guides with its axis in a horizontal position so as to be
driven by the friction of the rotating drum upon which it rests.
.
In this case a lever, or incline on a lever, is made to lift the bobbin from the
driving drum when a thread breaks, the lever being acted upon by a spring or weight.
When the threads are all present, the lever is sustained on a step in a part (fx)
secured to or formed upon the end of the T slide f, as explained in reference
to Fig. 7, and when the slide is moved endways the sustained end of the lever is
brought upon the incline upon the part fx, and the spring or weight then lifts the
bobbin and draws or forces the T slide at the same time so that its drop wires are
clear of the rotating ribbed boss (d').
Figs. 8, 9, and 10 illustrate the second part of our Invention.
The stop mechanism is similar to that hereinbefore described in reference
to Figs. 1 and 2, with the exceptions hereinafter mentioned.
a, the framing; a², rail for the stop mechanism; a', rails for the spindles.
The mechanism is illustrated as applied to one side of a double sided machine,
and only the stop mechanism for one spindle is shown.
d is the rotating shaft having a ribbed boss d' for each spindle applied to it with
a clutch box and pulley ; but in this case the pulley is only single grooved and
drives by a band * a pulley d³ secured on the boss of a larger pulley which
rotates on a stud carried in a bracket secured to the underside of the beain or
rail u².
A band do on the large pulley d drives the warf on the spindle b.
The spindle illustrated is supposed to be the ordinary spindle for the ring and
traveller, but a spindle with a flyer may be substituted.
The copping rail in both cases is arranged and worked in the ordinary manner.
It will be seen that when the pulley is thrown out of gear, the spindle & will
stop at the same time.
There is a bracket i also secured to the beam (a²) the upper end of which forms
a bearing to carry a shaft m passing from end to end of the machine and driving in
any convenient manner, to give the speed at which the threads are to be fed to be
twisted by the spindle (b), and this shaft m has a spur wheel m' upon it for each
spindle which gears with a spur wheel is on the end of a short shaft having its
bearings in a slide ³, the other end of the short shaft (i) having a grooved drum i²
secured upon it.
This slide also carries a stud which forms the axis upon which another grooved
drum 16 can rotate freely, and the slide also carries a wire curl or guide i*.
The lower end of the slide is fitted in slideways at the upper end of the
bracket i, and is secured by a plate i' and set screw, but so as to be able to inove
freely up and down.
The lower end of the slide is bevelled and rests upon an incline on the upper
side and at the end of the arm g³ of the lever g.

page_text: When the T slide f is moved endways by the ribbed boss the lever g is drawn
sideways by the spring (not shown in Fig. 10), and this movement throws the
clutch pulley d out of gear and stops the spindle b, and at the same time the
incline on the arm g³ of the lever g forces up the slide and takes the spur
wheel 3 out of gear with the wheel m' on the shaft m, which is constantly rotating,
and this stops the delivery of the threads to the spindle.
The threads pass through the detector mechanism, as explained in reference
to Figs. 1 and 2, unite at the guide wire or curl, pass over the drum i, under the
drum i, and over the drum 2, and then again under the drum 2, and soon as often
as required, the threads passing into the grooves of the drums, and when leaving
them pass to a curl or guide wire, or over a glass or other rod n between a slit,
and then to the "traveller" or flyer, as the caso may be, and on to the bobbin x
upon the spindle b.

of carrying the same into effect, and claim as our Invention,-
