PROVISIONAL SPECIFICATION left by the said John Horrocks and James
Horrocks at the Office of the Commissioners of Patents on the 22nd October

JOHN HORROCKS and JAMES HORROCKS of the City of Manchester in the
County of Lancaster Machine Makers. "IMPROVEMENTS IN MACHINERY OR
ARRANGEMENTS FOR DOUBLING AND WINDING, and DOUBLING TWISTING AND
WINDING YARNS OR THREADS."
Firstly. Our Invention relates to doubling and winding machinery where the
bobbin on to which the threads are wound is rotated on a vertical spindle or axis
and our Invention consists in new or improved combinations and arrangements of
mechanism.
In one combination forming our Invention the bobbin on which the threads are
wound is placed on a disc or a vertical spindle in suitable bearings which spindle
is driven by a band or otherwise from a "draw drum" or roller placed in bearings
with its axis in a vertical position this draw drum or roller being driven by bevel
toothed or friction wheels on a shaft passing from end to end of the machine.
This draw drum or roller is put out of gear when a thread breaks to stop the
winding by one arm of a lever having its fulcrum on a stud in a bracket secured on
the framing, this arm acting under a flange of the draw drum, to lift it vertically on
its axis out of gear or contact with the driving surface or wheel.
The other arm of this lifting lever has a weight suspended upon it, and the end
of this arm of the lever rests upon a projection in a plate which carries the
detector wires when the threads are all present, but when this plate for the detector
wires is moved to one side (as it is when a wire falls) the lever is allowed to slip
from the projection upon the plate and the bevelled end of the lever in its descent
pushes the detector plate further away from the teeth of the ratchet giving the
movement.

page_text: The plate for the detector wires has slots to guide the wires as they move up and
down and it is hinged or pivotted from its upper edge on horizontal axes
so that its lower edge will oscillate over the teeth of a ratchet on a shaft
underneath extending from end to end of the machine and which shaft is
constantly rotating.
When a thread breakes the wire sustained by it falls and comes in contact with
the teeth of the ratchet which moves the detector carrying plate to one side and
releases the end of the lever which stops the draw drum.
We also combine another lever with that above named so that when the latter
falls it will act upon the other lever which will be thus brought as a brake against
the bobbin on which the threads are being wound or against the spindle or disc
carrying the bobbin to stop the rotation which it has from momentum.
Another modification of our Invention consists in employing the arrangements
above described to stop a bobbin on a vertical axis on which the thread is being
wound, when a thread breaks or is absent, and where a "draw drum" is not used; the
lever in this case acting under the head of the bobbin to lift it off the driving disc
on the spindle. Or the above arrangement is employed to stop the spindle rotating
the bobbin when driven by a band working on fast and loose pulleys friction
clutches or bevel toothed or friction wheels the lever in this case acting to traverse
the band from the fast to the loose pulley or to bring the wheels or clutches out
of gear.
Secondly. Our Invention refers to doubling and winding machines where the
bobbin is on a horizontal axis and is rotated by the friction of the periphery of the
bobbin on the periphery of the driving drum, and consists in arranging the detector
mechanism and lever described under the first head of our Invention so that
according to one modification the lever will act under the periphery of the bobbin
and lift it out of contact with the surface of the driving drum when a thread
breaks and thus instantly stops its rotation; and by another modification the
lifting lever after lifting the bobbin acts upon another lever that lifts the bobbin
frame and thus the bobbin away from the first named lever to allow it to be freely
rotated to piece the threads. By another modification the bobbin is placed in an
oscillating frame which is lifted by the said lever to take the bobbins out of contact
with the driving drum when a thread breaks or is absent.
Thirdly. Our Invention relates to machines for doubling twisting and winding at
the same time in which both the winding and twisting is stoppel when a thread
breaks or is absent.
The arrangement of detector mechanism hereinbefore described for stopping the
draw drum when a thread breaks is combined with the arrangement hereinafter
described for driving and stopping the spindle for twisting the threads.
When a pulley is used for driving the spindle by a band working on a warf on
the spindle; The pulley is loose on the shaft and is driven by a friction clutch and
an arm of the lever for acting upon the draw roller is jointed with a rod having
reverse inclines upon it which act upon a bevel flange on the pulley in one
direction to push the pulley in contact with the friction clutch and in the other
direction to withdraw the pulley from the clutch and stop its rotation and thus
that of the spindle when a thread breaks or is absent.
By another arrangement the pulley is kept in contact with its friction clutch by
a helical spring on the shaft and it is forced out of contact by the bevelled rod or
equivalent arrangements to stop the rotation of the spindle.
Another arrangement according to our Invention, when the spindle is driven by
friction cones
or discs or by fast and loose pulleys, consists in placing the part
which is driven by a band from a pulley or tin roller on a tubular bearing apart
from the spindle, this bearing is or may be the bolster or collar for the spindle
lengthened for the pulley warf cone or disc to rotate upon or it is or may be the
step made to extend upwards. If friction cones or friction discs are used the lever
in connection with the detector mechanism is made to act on a lever which is a
fork to move the driven cone or disc out of contact with the cone or disc fast on

page_text: the spindle and thus the rotating friction of the driven cone or disc on its bearing
does not tend to drive the spindle as it does when the bearing is directly upon the
spindle.
When the spindle is driven by a fast and loose warf the fast warf is secured to
the spindle and the loose warf works on the prolongation of the bolster or step and
the band is traversed from the fast to the loose pulley or warf to stop the spindle.

Sections 18 to 21 of the Patents, Designs, and Trade Marks Act, 1883.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Horrocks and James Horrocks in the Great Seal Patent
Office on the 21st April 1880.
JOHN HORROCKS and JAMES HORROCKS of the City of Manchester in the
County of Lancaster, Machine Makers. "IMPROVEMENTS IN MACHINERY OR
ARRANGEMENTS FOR DOUBLING AND WINDING AND DOUBLING, TWISTING AND
WINDING YARNS OR THREADS."
Firstly, Our Invention relates to doubling and winding machinery where the
the bobbin on to which the threads are wound is rotated on a vertical spindle or
axis, and our Invention consists in new or improved combinations and arrangements
of mechanism.
. In one combination forming our Invention the bobbin on which the threads are
wound is placed on a disc on a vertical spindle in suitable bearings, which spindle
is driven by a band or otherwise from a draw drum or roller placed in bearings
with its axis in a vertical position, this draw drum or roller being driven by bevel
toothed or friction wheels on a shaft passing from end to end of the machine.
This draw drum or roller is put out of gear when a thread breaks to stop the
winding by one arm of a lever having its fulcrum on a stud in a bracket secured
on the framing this arm acting under a flange of the draw drum to lift it vertically
on its axis out of gear or contact with the driving surface or wheel.
The other arm of this lifting lever has a weight suspended to or formed upon it
and the bent end or a bent projection held by the end of this arm of the lever rests
upon a pin or projection in a plate which carries the detector wires when the
threads are all present, but when this plate for the detector wires is moved to one
side (as it is when a wire falls) the lever or the bent projection in it is allowed to
slip from the projection or wire upon the plate and the bevelled or bent end of the
lever or projection in its descent draws the detector plate further away from the
teeth of the ratchet or sides of the rotating bar or shaft giving the movement.
The plate for the detector wires has slots or spaces to guide the wires as they
move up and down and it is hinged or pivotted from its upper edge on horizontal
axes so that its lower edge will oscillate over the teeth of a ratchet on a shaft or
the shaft or bar underneath extending from end to end of the machine and which
shaft or bar is constantly rotating. When a thread breaks the wire sustained by
it falls and comes in contact with the sides of the bar or the teeth of the ratchet

page_text: which moves the detector carrying plate to one side and releases the bent end of
the lever or the bent projection in it which stops the draw drum. Another
modification of our Invention consists in employing the arrangements above
described to stop a bobbin on a vertical axis on which the thread is being wound
when a thread breaks or is absent and where a draw drum is not used, the lever
in this case acting under the head of the bobbin to lift it off the driving disc on
the spindle.
Or the above arrangement is employed to stop the spindle rotating the bobbin
when driven by a band working on fast and loose pulleys or by friction clutches
or bevel toothed wheels or friction wheels, the lever in this case acting to traverse
the band from the fast to the loose pulley or to bring the wheels or clutches out
of gear.
Secondly, Our Invention refers to doubling and winding machines where the
bobbin is placed on a horizontal axis and is rotated by the friction of the periphery
of the hobbin upon the periphery of the driving drum, and consists in arranging
the detector mechanism and lever described under the first head of our Invention
so that according to one modification the lever will act under the periphery of the
bobbin and lift it out of contact with the surface of the driving drum when a thread
breaks and thus instantly stop its rotation.
By another modification the bobbin is placed in an oscillating frame which is
lifted by the said lever to take the bobbin out of contact with the driving drum
when a thread breaks or is absent.
Thirdly, Our Invention relates to machines for doubling twisting and winding
at the same time, in which both the winding and twisting are stopped when a
thread breaks or is absent.
1
The arrangement of detector mechanism hereinbefore described for stopping the
draw drum when a thread breaks is combined with the arrangement hereinafter
described for driving and stopping the spindle for twisting the threads.
Another arrangement according to our Invention when the spindle is driven by
friction cones or discs or by fast and loose pulleys, consists in placing the part
which is driven by a band from a pulley or tin roller on a tubular bearing apart
from the spindle, this bearing is or may be the bolster or collar for the spindle
lengthened for the pulley, warf, cone or disc to rotate upon, or it is or may be the
step made to extend upwards. If friction cones or friction discs are used the lever
in connection with the detector mechanism is made to act on a lever which is a
fork or directly on a fork to move the driven cone or disc out of contact with the
cone or disc fast upon or rotating with the spindle, and thus the rotating friction of
the driven cone or disc on its bearing does not tend to drive the spindle as it does
when the bearing is directly upon the spindle.
When the spindle is driven by a fast and loose warf the fast warf is secured to
the spindle and the loose warf works on the prolongation of the bolster or step
and the band is traversed from the fast to the loose pulley or warf to stop the
spindle.
Fig. 1 is a sectional elevation of a doubling and winding arrangement with a
draw drum and with the bobbin upon which the thread is being wound in a vertical
position.
The arrangement of the parts of this combination are similar to that modification
described in the Specification of John and James Horrocks and Edward Whalley's
Patent dated June 23 A.D. 1877 and numbered 2439 and illustrated by Figs. 14
and 15 of the Drawings, with the exceptions that the detector mechanism and its
action upon the draw drum is different.
The detector mechanism consists of an oscillating plate a, carrying the detector
wires a¹; When these wires are held up, a wire carried upon the oscillating plate
holds up one end of a lever b, but when one or more of the detector wire fall the
lower end of such detector wire comes in contact with a rotating shaft or ratchet c,
which moves the oscillating plate a, on one side and releases the lever b, and the
other end of the lever comes under the edge of the draw drum d and lifts it so

page_text: .
that the friction bevel upon it is brought out of contact with the friction driving
bevel or wheel-The end of the lever b is made heavy enough or has a weight
attached to it sufficient to lift the draw drum d. The construction of the detector
mechanism will be hereinafter more particularly described.
e, is the beam passing from end to end of the frame carrying the cleaning plates
(e) the tube e covered with flannel over which the threads pass and the pivots a²
of the oscillating plates.
The lever for lifting the draw drum d, has its fulcrum on a bracket b', secured to
the beam which passes from end to end of the frame which carries the bearings for
the driving shaft d' and fixed studs for the vertical drums to rotate upon. is the rod
for distributing the threads upon the bobbins g as it is wound, each bobbin being upon
a spindle in suitable bearings driven by a band or tape g² from the draw drum d.
The gearing for driving the shaft d² and working the traverse rod is of any
ordinary arrangement.
.
The threads being wound are drawn from cops, bobbins or "swifts" arranged in
any ordinary manner and pass through the slits in the cleaning plates (el) over the
friction rail e², each separate thread through a separate "curl" or hook in the
detector wires (a¹) held in the oscillating plate, over the guide rod 4, then partly
round the draw drum d and the pulley loose on a pin or stud, then over the
traverse rod to the bobbin g. Fig. 2 illustrates a modification similar to that
shown by Fig. 1, with the exception that the draw drum d, is supposed to be driven
by a band from a tin drum . The band works upon and rotates a warf on the
same stud as the draw drum, and there is a clutch on the warf which gears with
one on the boss of the draw drum, so that when the draw drum is lifted by the
lever the clutch is brought out of gear and the draw drum stops. The lever bis
shown with a weight 2 formed upon its end.
In Figs. 1 and 2 the hook or handle 63 is to lift the lever when the winding is to
begin. Fig. 3 shows a modification in which a cone or other friction clutch is sub-
stituted for the toothed clutch shown in Fig. 2.
Fig. 4 illustrates a combination and arrangement according to our Invention
where the threads are being wound on a bobbin on a vertical spindle in an ordinary
and well known manner, the bobbin being rotated by resting upon the friction disc
upon the spindle. The detector and connected mechanism is similar to that shown
in Fig. 2, but the end of the lever is made to act upon the under head of the
bobbin outside the friction disc and this lifts the bobbin from it and thus stops
its rotation when a thread breaks or is absent. The threads pass from the detector
wires over the rod h and over the traverse rod f to the bobbin g. Fig. 5 illustrates
another modification similar to that shown by Fig. 4, where the spindle g¹ is driven
by a band or tape working on a pulley or tin drum, and on a fast and loose warf. The
collar or bolster for the spindle is lengthened to receive the loose warf g², which is
held up by a shoulder on the collar or other suitable means, the driving warf g³ is fast
on the spindle and works as close as possible without friction or contact with the
loose warf g. The spindle g is stopped by traversing the driving band from the
fast to the loose warf and started by the reverse movement, and this is done by
guide pins on a lever b.
When the detector end of the lever is lifted, the band is brought on the warf
fast on the spindle, and when the detectors act, the weight on the detector end of
the lever traverses the driving band on to the loose warf 2, and the friction of
the loose warf being on the bolster it does not act to drive the spindle which con-
sequently stops quickly.
Fig. 6 illustrates another modification similar to that shown by Fig. 5 except
that the driving band or tape works on a warf that rotates upon the bolster of the
spindle, the warf g is tubular and is coned at its lower end to fit a cone o secured
upon the spindle g. The weight acting upon the detector end of the lever b when
it is released causes the other end of the lever to act under the collar or shoulder on
the warf and lift it from the cone on the spindle and thus stop its rotation.
Discs or other friction surfaces are or may be used in place of the cones.

page_text: Fig. 7 is a cross sectional elevation illustrating two modes of carrying out our
Invention when the axis of the bobbin upon which the threads are to be wound is in
a horizontal position with its periphery in contact with a drum by which it is rotated.
Fig. 8 is an end elevation and Fig. 9 a plan showing an enlarged detached view
of some of the parts shown by Fig. 7.
Fig. 10 is an end, Fig. 11 an end section, Fig. 12 a front view partly in section
and Fig. 13 a plan or edge view illustrating the mode of constructing our improved
oscillating detector plate which is shown detached and full size.
We will first describe the modification shown on the left hand side of Figs. 7. 8.
and 9 where the axis of the bobbin rotates in fixed inclined guides.
The inclined guides j. for the ends of the spindle on which the bobbin 1 rotates is
formed in brackets secured to a carrier beain . When a double machine is made
with both sides alike the incline brackets j to guide the ends of the spindles or axes
of the bobbins are or may be made double as shown in Fig. 14 secured to a beam
passing from end to end of the frame immediately under the drum shaft k. One
bracket guides and holds the ends of the spindle of a bobbin on each side of it
except the guides at the ends of the frames.
To a projection from the incline bracket jan adjustable bracket jx is secured to
carry the fulcrum of a lever b, one end of which passes under the bobbin (¹) when
in working position, the other end carries a bent or cranked wire which is
secured in it so as to be adjustable by a set screw. The end of this bent wire rests
upon a wire a screwed in projections from the oscillating detector plate a, which
has pivots a² at each end, resting in grooves in brackets secured to or cast with a
beam e passing from end to end of the frame.
The oscillating plate a, by its own weight and the weight of and on the lever b,
is forced against a stop formed by a shoulder on the bearing e³ for the pivots a²
so that it cannot move further in that direction, but when one or more detector
wires (a) fall from the breakage or absence of a thread or threads, the end of the
wire or wires so falling comes in contact with ratchets on a rotating shaft below or
with a shaft or bar c, of triangular or other section, which rotates in the direction
pointed by the arrow and moves the oscillating plate a, so that the wire a³ carried
in the projections from the plate a, moves under the end of the bent wire which
thus slips off, and the weight of the lever alone or with the addition of a weight
attached or suspended to it causes it to descend and lift the bobbin sufficiently to
take it clear of the driving drum k¹.
.
The bent wire in its descent pulls the oscillating plate a more towards it, and this
movement can be increased or diminished according to the position of the fulcrum
of the lever b, or the angle of the bent wire . This movement given to the
oscillating plate takes its projecting detector wires a clear of the ratchet or rotating
shaft c.
Instead of the wire a³ for sustaining the bent wire being carried as shown in
Figs. 7, 8 and 9 it is or may be arranged as illustrated by Fig. 15 a partial side
view and Fig. 16 a partial front view of the detector mechanism, namely, in two
projections from the upper edge and at one end of the oscillating plate a.
The lever b, may then be of the form shown, and the bent wire with a projection
to rest upon the supporting wire as when the lever b descends.
:
The threads to be "doubled" or wound are drawn from cops (as shown) see
Fig. 7, or from bobbins or swifts arranged in any ordinary manner, they each pass
through a shit in a cleaning and guide plate e over the tube e² covered with flannel
to give friction and clean the threads through the curls or hooks (a) in the detector
wires, up to the pulley x as shown in Fig. 7 down through the space in the adjust-
able guide on the horizontal traverse bar for distributing the threads (which
bar is actuated in any ordinary manner) and then on to the bobbin j¹.
When the bobbin has been stopped the attendant lifts it so that its spindle or
pivots rest in the hollow at the top of the incline guides j, and this allows it to
rotate freely to find the ends of the thread, and when tied the bobbin is put back
into the incline guides and rests upon the end of the lever b, then the attendant

page_text: lifts the lever by means of the hook and holds it for a moment, and this allows
the oscillating plate a to move by its own weight against the stop e, when it will
sustain the end of the bent wire ', and thus the lever when sufficient tension
has come upon the threads to hold up the detector wires (a¹).
The oscillating plate a is constructed by preference as shown by Figs. 10 to 13
both Figures inclusive. It consists of a flat rectangular plate a with a pivot a² at
each end.
It has three ribs a passing lengthway, which have as many grooves cut across
them as there are to be detector wires a' carried by the plate. Each of these wires
a¹ is bent as shown in Fig. 12 and when all the detector wires are placed in their slots
a thin plate or cover a is slided into grooves or notches in projections at each end.
The bend ax in each wire limits its movement up and down and prevents it
from turning.
In the modification shown on the right hand side of Figs. 7, 8 and 9 the spindle
of the bobbin on which the threads are being wound is carried in a frame that
can oscillate on rod j passing from end to end of the frame which rod is supported
on brackets secured to the beam below. Each frame j³ is grooved to receive the
ends of the spindles or axis for the bobbin jas shown.
The detector mechanism in this modification is similar to that shown on the left-
hand side of Figs. 8 and 9.
The fulcrum of the lever b, is on a stand & secured to the beam which extends
from end to end of the frame and when it descends from the absence of a thread
or threads the bobbin is lifted away from the driving drum . The attendant
then lifts the frame j³ until a prop j5 (jointed to the frame on a stud) is vertical,
and this holds the frame with the bobbin j' clear of the drum k¹ to allow it to be
rotated to find the "ends" and when pieced the lever is lifted by the hook b³ and
by this movement a projection from the lever pushes the lower end of the
prop to one side and allows the frame j³ to fall and bring the bobbin j¹ against
the driving drum k¹.
Fig. 17 is a side elevation of a combination. similar except in the detector
mechanism and its combination with the actuating lever, to that described in the
Specification of Letters Patent. granted to James Horrocks dated June 10th 1878
numbered 2318 and illustrated by Figures 3 and 4 of the Drawings.
The bobbin marked () in the said Figures on which the threads are wound is
carried in an oscillating frame (d) which is lifted when a thread breaks or is absent
by the lever (2) centred on the same shaft (d') as the oscillating frame (d). One
arm of the lever d² carries the bent wire bt.
The other parts of the detector mechanism will be understood from the letters
of reference hitherto used for those parts and the previous description.
The oscillating frame d, may if desired be hinged from a shaft or axis above
the drum.
Fig. 18 is a sectional elevation illustrating our improvements in doubling,
twisting and winding. 1, framing; bean or bar extending the length of the
frame having projections to carry the vertical stud on which the "draw drum" m
rotates, each drum having a bevel upon it driven by a bevel wheel on the hori-
zontal shaft m passing from end to end of the frame and geared with the main
driving shaft in any convenient manner.
On another projection from the beam or bar - the fulcrum of a lever n is carried
which has one arm that passes on one side of the draw drum m, a projection from
this arm coming under the edge, of the drum so as to lift it on its stud and throw
it out of gear when the weighted end of the lever n falls. The end of this arm of
the lever, has an arm jointed to it to carry the thread guide and it can be
turned up to a right angle to the position in which it is shown in Fig. 18 when
the bobbin is to be removed from the spindle.
Another arm of the lever n has two branches, one to carry the bent wire b*, the
other to act as a weight or to have a weight suspended upon it. The lever is
held up by the end of the bent wire resting upon the cross wire a³ carried on

page_text: the oscillating plate a, of the detector mechanism, the arrangement of which will be
understood from the Drawings and previous description.
:
There is another arm of the lever n to which a vertical rod is jointed that
has an adjustable fork at its lower end that comes between grooves on the
boss of a warf which rotates upon an extension of the bolster of the spindle p,
the lower part of the warf is coned and may be covered on its surface with leather
and fits into a cone cup p² fast on the spindle 1).
The warf p is driven by a band from a pulley or tin drum and when in the
position shown it is in contact with the cone cup 2 and is driving the spindle,
but when the weight end of the lever n falls, the fork lifts the warf p upwards
so that it rotates freely on the bolster without contact with or rubbing against the
spindle and the spindle stops.,
To cause it to stop more suddenly if desired another fork or elastic projection is
or may be secured on the rod to come below the cone cup p² fixed upon the
spindle and to come in contact with the underside of the cone cup about the
time when the weight end of the lever n, has descended to its lowest position.
The rod n² hangs vertically and each rod for each spindle is kept towards the
spindle by a rod or bar a passing from end to end of the frame.
The threads pass from cops, bobbins or
"Swifts "
in any suitable crecl, over a
rod each thread through the hook or curl in the detector wire, through the guide
eye, round the draw drum m, through the eye in the lever to the bobbin on
the, spindle.
Fig. 19 is a side and Fig. 20 a plan view illustrating a modification where the
draw drum m is carried on a stud placed in a horizontal position, the drum being
driven by spur toothed wheels.
When the weighted end of the lever n falls it lifts the wheel on the draw drum m
out of gear with the spur wheel on the shaft m'.
The fever in some cases is made to carry a stud for a pulley mx made of wood
by preference and the threads may pass several times round the draw drum m and
pulley m before going to the guide eye.
Fig. 21 is an illustration showing the warf pl for driving the spindle arranged
to rotate on an elongated foot step bearing the cone p² to fit its cup, being arranged
to rotate with the spindle p but slide up and down it, there being a pin or fixed
key in the spindle to fit keyways in the boss of the cone. The cone is lifted by
a fork n³ as shown in Fig. 18. Fig. 22 illustrates our Invention for driving the
spindle p by a fast and loose warf when the loose warf p³ rotates on an elongation
of the bolster as shown.
The driving band is traversed by a guide on the rod from the fast warf p
to the loose warf when the rotation of the spindle is to be stopped when a thread
breaks or is absent.
The cones on the spindle shown in Figs. 18 and 21 may be reversed if desired,
for instance it is obvious that the cup cone in Fig. 18 inay be on the warf and
the external cone fast on the spindle.
Flat dises may also be used in place of cones if desired.
We have now particularly described the nature of our said Invention and the
modes of carrying the same into effect and would have it known, that we are aware
that oscillating plates carrying detector wires have been proposed to be used in com-
bination with a rotating ratchet wiper or cam and that ice do not in and by our first
claim make any claim to any combination of such mechanism with a lerer for the
purposes described except when constructed and acting substantially as in this Speci-
fication described and illustrated by the drawings hereto, and that in and by the
second claim we do not claim separately the parts shown in Fig. 3 or Figs. 14, 15
and 16, but only when used in combination with the other portions of the mechanism
as described in this specification and illustrated by the drawings hereto and that in
and by the fifth claim of the original specification we claim only the construction of
the entire combination of oscillating plates and detector wires with a bend as in this

"IMPROVEMENTS IN MACHINERY OR ARRANGEMENTS FOR DOUBLING AND
WINDING, AND DOUBLING, TWISTING, AND WINDING YARNS OR THREADS."
Sealed the 9th April 1880, and dated the 22nd October 1879.
PROVISIONAL SPECIFICATION left by the said John Horrocks and James
Horrocks the Office of the Commissioners of Patents on the 22nd October
1879.
JOHN HORROCKS and JAMES HORROCKS, of the City of Manchester, in the
County of Lancaster, Machine Makers. "IMPROVEMENTS IN MACHINERY OR
ARRANGEMENTS FOR DOUBLING AND WINDING, AND DOUBLING, TWISTING, AND
WINDING YARNS OR THREADS."
Firstly. Our Invention relates to doubling and winding machinery where the
bobbin on to which the threads are wound is rotated on a vertical spindle or axis,
and our Invention consists in new or improved combinations and arrangements of
mechanism.
"
In one combination forming our Invention the bobbin on which the threads are
wound is placed on a disc or a vertical spindle in suitable bearings, which spindle.
is driven by a band or otherwise from a "draw drum' or roller placed in bearings
with its axis in a vertical position, this draw drum or roller being driven by bevel
toothed or friction wheels on a shaft passing from end to end of the machine.
This draw drum or roller is put out of gear when a thread breaks to stop the
winding by one arm of a lever having its fulcrum on a stud in a bracket secured on
the framing, this arm acting under a flange of the draw drum to lift it vertically on
its axis out of gear or contact with the driving surface or wheel.
The other arm of this lifting lever has a weight suspended upon it, and the end
of this arm of the lever rests upon a projection in a plate which carries the
detector wires when the threads are all present, but when this plate for the detector
wires is moved to one side (as it is when a wire falls) the lever is allowed to slip
from the projection upon the plate, and the bevelled end of the lever in its descent
pushes the detector plate further away from the teeth of the ratchet giving the
novement.

page_text: The plate for the detector wires has slots to guide the wires as they move up and
down, and it is hinged or pivotted from its upper edge on horizontal axes,
so that its lower edge will oscillate over the teeth of a ratchet on a shaft
underneath extending from end to end of the machine, and which shaft is
constantly rotating.
When a thread breakes the wire sustained by it falls and comes in contact with
the teeth of the ratchet, which moves the detector carrying plate to one side, and
releases the end of the lever which stops the draw drum.
We also combine another lever with that above named, so that when the latter
falls it will act upon the other lever, which will be thus brought as a brake against 1
the bobbin on which the threads are being wound or against the spindle or disc
carrying the bobbin to stop the rotation which it has from momentum.
22
Another modification of our Invention consists in employing the arrangements
above described to stop a bobbin on a vertical axis on which the thread is being
wound when a thread breaks or is absent, and where a draw drum" is not used, the 1
lever in this case acting under the head of the bobbin to lift it off the driving dise
on the spindle. Or the above arrangement is employed to stop the spindle rotating
the bobbin when driven by a band working on fast and loose pulleys, friction
clutches, or bevel toothed or friction wheels, the lever in this case acting to traverse
the band from the fast to the loose pulley or to bring the wheels or clutches out
of gear.
Secondly. Our Invention refers to doubling and winding machines where the
bobbin is on a horizontal axis and is rotated by the friction of the periphery of the
bobbin on the periphery of the driving drum, and consists in arranging the detector
mechanism and lever described under the first head of our Invention so that,
according to one modification, the lever will act under the periphery of the bobbin,
and lift it out of contact with the surface of the driving drum when a thread
breaks, and thus instantly stops its rotation, and by another modification the
lifting lever after lifting the bobbin acts upon another lever that lifts the bobbin
frame, and thus the bobbin away from the first named lever to allow it to be freely
rotated to piece the threads. By another modification the bobbin is placed in an
oscillating frame which is lifted by the said lever to take the bobbins out of contact
with the driving drum when a thread breaks or is absent.
Thirdly. Our Invention relates to machines for doubling, twisting, and winding at
the same time, in which both the winding and twisting is stopped when a thread
breaks or is absent.
The arrangment of detector mechanism hereinbefore described for stopping the
draw drum when a thread breaks is combined with the arrangement hereinafter
described for driving and stopping the spindle for twisting the threads.
When a pulley is used for driving the spindle by a band working on a warf on
the spindle the pulley is loose on the shaft, and is driven by a friction clutch, and
an arm of the lever for acting upon the draw roller is jointed with a rod having
reverse inclines upon it, which act upon a bevel flange on the pulley in one
direction to push the pulley in contact with the friction clutch, and in the other
direction to withdraw the pulley from the clutch and stop its rotation, and thus
that of the spindle, when a thread breaks or is absent.
By another arrangement the pulley is kept in contact with its friction clutch by
a helical spring on the shaft, and it is forced out of contact by the bevelled rod. or
equivalent arrangements to stop the rotation of the spindle.
Another arrangement according to our Invention, when the spindle is driven by
friction cones or discs, or by fast and loose pulleys, consists in placing the part
which is driven by a band from a pulley or tin roller on a tubular bearing apart
from the spindle; this bearing is or may be the bolster or collar for the spindle
lengthened for the pulley, warf, cone, or disc to rotate upon, or it is or may be the
step made to extend upwards. If friction cones or friction discs are used, the lever
in connection with the detector mechanism is made to act on a lever which is a
fork to move the driven cone or disc out of contact with the cone or disc fast on

page_text: the spindle, and thus the rotating friction of the driven cone or disc on its bearing
does not tend to drive the spindle, as it does when the bearing is directly upon the
spindle.
When the spindle is driven by a fast and loose warf, the fast warf is secured to
the spindle, and the loose warf works on the prolongation of the bolster or step, and
the band is traversed from the fast to the loose pulley or warf to stop the spindle.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Horrocks and James Horrocks in the Great Seal Patent
Office on the 21st April 1880.
JOHN HORROCKS and JAMES HORROCKS, of the City of Manchester, in the
County of Lancaster, Machine Makers. "IMPROVEMENTS IN MACHINERY OR
ARRANGEMENTS FOR DOUBLING AND WINDING, AND DOUBLING, TWISTING, AND
WINDING YARNS OR THREADS."
Firstly. Our Invention relates to doubling and winding machinery where the
the bobbin on to which the threads are wound is rotated on a vertical spindle or
axis, and our Invention consists in new or improved combinations and arrangements
of mechanism.
In one combination forming our Invention the bobbin on which the threads are
wound is placed on a disc on a vertical spindle in suitable bearings, which spindle
is driven by a band or otherwise from a draw drum or roller placed in bearings
with its axis in a vertical position, this draw drum or roller being driven by bevel
toothed or friction wheels on a shaft passing from end to end of the machine.
This draw drum or roller is put out of gear when a thread breaks to stop the
winding by one arm of a lever having its fulcrum on a stud in a bracket secured
on the framing, this arm acting under a flange of the draw drum to lift it vertically
on its axis out of gear or contact with the driving surface or wheel.
The other arm of this lifting lever has a weight suspended to or formed upon it,
and the bent end or a bent projection held by the end of this arm of the lever rests
upon a pin or projection in a plate which carries the detector wires when the
threads are all present, but when this plate for the detector wires is moved to one
side (as it is when a wire falls), the lever or the bent projection in it is allowed to
slip from the projection or wire upon the plate, and the bevelled or bent end of the
lever or projection in its descent draws the detector plate further away from the
teeth of the ratchet or sides of the rotating bar or shaft giving the movement.
The plate for the detector wires has slots or spaces to guide the wires as they
move up and down, and it is hinged or pivotted from its upper edge on horizontal
axes, so that its lower edge will oscillate over the teeth of a ratchet on a shaft or
the shaft or bar underneath extending from end to end of the machine, and which
shaft or bar is constantly rotating. When a thread breaks the wire sustained by
it falls and comes in contact with the sides of the bar or the teeth of the ratchet,

page_text: which moves the detector carrying plate to one side, and releases the bent end of
the lever or the bent projection in it, which stops the draw drum. Another
modification of our Invention consists in employing the arrangements above
described to stop a bobbin on a vertical axis on which the thread is being wound
when a thread breaks or is absent, and where a draw drum is not used, the lever
in this case acting under the head of the bobbin to lift it off the driving disc on
the spindle.
Or the above arrangement is employed to stop the spindle rotating the bobbin
when driven by a band working on fast and loose pulleys, or by friction clutches,
or bevel toothed wheels, or friction wheels, the lever in this case acting to traverse
the band from the fast to the loose pulley or to bring the wheels or clutches out
of gear.
Secondly. Our Invention refers to doubling and winding machines where the
bobbin placed on a horizontal axis, and is rotated by the friction of the periphery
of the bobbin upon the periphery of the driving drum, and consists in arranging
the detector mechanism and lever described under the first head of our Invention
so that according to one modification the lever will act under the periphery of the
bobbin, and lift it out of contact with the surface of the driving drum when a thread
breaks, and thus instantly stop its rotation.
By another modification the bobbin is placed in an oscillating frame, which is
lifted by the said lever to take the bobbin out of contact with the driving drum
when a thread breaks or is absent.
Thirdly. Our Invention relates to machines for doubling, twisting, and winding
at the same time, in which both the winding and twisting are stopped when a
thread breaks or is absent.
The arrangement of detector mechanism herein before described for stopping the
draw drum when a thread breaks is combined with the arrangement hereinafter
described for driving and stopping the spindle for twisting the threads.
Another arrangement according to our Invention, when the spindle is driven by
friction cones or discs, or by fast and loose pulleys, consists in placing the part
which is driven by a band from a pulley or tin roller on a tubular bearing apart
from the spindle; this bearing is or may be the bolster or collar for the spindle
lengthened for the pulley, warf, cone, or disc to rotate upon, or it is or may be the
step made to extend upwards. If friction cones or friction discs are used the lever
in connection with the detector mechanism is made to act on a lever which is a
fork or directly on a fork to move the driven cone or disc out of contact with the
cone or disc fast upon or rotating with the spindle, and thus the rotating friction of
the driven cone or disc on its bearing does not tend to drive the spindle, as it does
when the bearing is directly upon the spindle.
When the spindle is driven by a fast and loose warf the fast warf is secured to
the spindle, and the loose warf works on the prolongation of the bolster or step,
and the band is traversed from the fast to the loose pulley or warf to stop the
spindle.
Fig. 1 is a sectional elevation of a doubling and winding arrangement with a
draw drum, and with the bobbin upon which the thread is being wound in a vertical
position.
The arrangement of the parts of this combination are similar to that modification
described in the Specification of John and James Horrocks and Edward Whalley's
Patent dated June 23 A.D. 1877, and numbered 2429, and illustrated by Figs. 14
and 15 of the Drawings, with the exceptions that the detector mechanism and its
action upon the draw drum is different.
The detector mechanism consists of an oscillating plate a carrying the detector
wires a'. When these wires are held up a wire carried upon the oscillating plate
holds up one end of a lever b, but when one or more of the detector wires fall the
lower end of such detector wire comes in contact with a rotating shaft or ratchet c
which moves the oscillating plate a on one side and releases the lever b, and the
other end of the lever comes under the edge of the draw drum d, and lifts it so

page_text: that the friction bevel upon it is brought out of contact with the friction driving
bevel or wheel. The end of the lever b is made heavy enough or has a weight
attached to it sufficient to lift the draw drum d. The construction of the detector
mechanism will be hereinafter more particularly described.
e is the beam passing from end to end of the frame carrying the cleaning plates
(e), the tube e covered with flannel over which the threads pass, and the pivots a
of the oscillating plates.
The lever b for lifting the draw drum d has its fulcrum on a bracket b' secured'
to the beam d¹, which passes from end to end of the frame which carries the bearings
for the driving shaft d² and fixed studs for the vertical drums to rotate upon. fis
the rod for distributing the threads upon the bobbins y as it is wound, each bobbin
being upon a spindle g¹ in suitable bearings driven by a band or tape g² from the
draw drum d.
The gearing for driving the shaft d² and working the traverse rod is of any
ordinary arrangement.
The threads being wound are drawn from cops, bobbins, or "swifts" arranged in
any ordinary manner, and pass through the slits in the cleaning plates (e') over the
friction rail e, each separate thread through a separate "curl" or hook in the
detector wires (a¹) held in the oscillating plate over the guide rod h, then partly
round the draw drum d and the pulley h¹ loose on a pin or stud, then over the
traverse rod to the bobbin g. Fig. 2 illustrates a modification similar to that
shown by Fig. 1, with the exception that the draw drum d is supposed to be driven
by a band from a tin drum i. The band works upon and rotates a warf on the
same stud as the draw drum, and there is a clutch on the warf which gears with
one on the boss of the draw drum, so that when the draw drum is lifted by the
lever 6 the clutch is brought out of gear and the draw drum stops. The lever b is
shown with a weight 62 formed upon its end.
In Figs. 1 and 2 the hook or handle 63 is to lift the lever when the winding is to
begin. Fig. 3 shows a modification in which a cone or other friction clutch is sub-
stituted for the toothed clutch shown in Fig. 2.
Fig. 4 illustrates a combination and arrangement according to our Invention,
where the threads are being wound on a bobbin on a vertical spindle in an ordinary
and well known manner, the bobbin being rotated by resting upon the friction disc
upon the spindle. The detector and connected mechanism is similar to that shown
in Fig. 2, but the end of the lever b is made to act upon the under head of the
bobbin g. outside the friction disc, and this lifts the bobbin from it, and thus stops
its rotation when a thread breaks or is absent. The threads pass from the detector
wires over the rod h and over the traverse rod f to the bobbin g. Fig. 5 illustrates
another modification similar to that shown by Fig. 4, where the spindle g' is driven
by a band or tape working on a pulley or tin drum and on a fast and loose warf. The
collar or bolster for the spindle is lengthened to receive the loose warf g², which is
held up by a shoulder on the collar or other suitable means; the driving warf g³ is fast
on the spindle, and works as close as possible without friction or contact with the
loose warf g². The spindle g¹ is stopped by traversing the driving band from the
fast to the loose wart, and started by the reverse movement, and this is done by
guide pins on a lever b.
When the detector end of the lever b is lifted the band is brought on the warf
fast on the spindle, and when the detectors act the weight on the detector end of
the lever b traverses the driving band on to the loose warf g², and the friction of
the loose warf being on the bolster it does not act to drive the spindle, which con-
sequently stops quickly.
Fig. 6 illustrates another modification similar to that shown by Fig. 5, except
that the driving band or tape works on a warf that rotates upon the bolster of the
spindle; the warf g is tubular, and is coned at its lower end to fit a cone g³ secured
upon the spindle g¹. The weight acting upon the detector end of the lever b, when
it is released causes the other end of the lever to act under the collar or shoulder on
:

page_text: the warf g and lift it from the cone go on the spindle, and thus stop its rotation.
Discs or other friction surfaces are or may be used in place of the cones.
Fig. 7 is a cross sectional elevation illustrating two modes of carrying out our
Invention when the axis of the bobbin upon which the threads are to be wound is
in a horizontal position, with its periphery in contact with a drum by which it is
rotated.
Fig. 8 is an end elevation, and Fig. 9 a plan showing an enlarged detached view
of some of the parts shown by Fig. 7.
Fig. 10 is an end, Fig. 11 an end section, Fig. 12 a front view partly in section,
and Fig. 13 a plan or edge view illustrating the mode of constructing our improved
oscillating detector plate, which is shown detached and full size.
We will first describe the modification shown on the left hand side of Figs. 7, 8,
and 9, where the axis of the bobbin rotates in fixed inclined guides.
The inclined guides ; for the ends of the spindle on which the bobbin j¹ rotates is
formed in brackets secured to a carrier beam . When a double machine is made
with both sides alike the incline brackets j to guide the ends of the spindles or axes
of the bobbins are or may be made double, as shown in Fig. 14, secured to a beam
passing from end to end of the frame immediately under the drum shaft k. One
bracket guides and holds the ends of the spindle of a bobbin on each side of it,
except the guides at the ends of the frames.
To a projection from the incline bracket ; an adjustable bracket j* is secured to
carry the fulcrum of a lever b, one end of which passes under the bobbin (j') when
in working position; the other end carries a bent or cranked wire b', which
secured in it so as to be adjustable by a set screw. The end of this bent wire rests
upon a wire a³ screwed in projections from the oscillating detector plate a, which
has pivots a at each end resting in grooves in brackets e³ secured to or cast with a
beam e passing from end to end of the frame.
The oscillating plate a, by its own weight and the weight of and on the lever b,
is forced against a stop formed by a shoulder e' on the bearing es for the pivots a²,
so that it cannot move further in that direction; but when one or more detector
wires (a) fall from the breakage or absence of a thread or threads the end of the
wire or wires so falling comes in contact with ratchets on a rotating shaft below, or
with a shaft or bar c of triangular or other section, which rotates in the direction
pointed by the arrow and moves the oscillating plate a, so that the wire as carried
in the projections from the plate a moves under the end of the bent wire 64, which
thus slips off, and the weight of the lever b alone, or with the addition of a weight
attached or suspended to it, causes it to descend and lift the bobbin j² sufficiently to
take it clear of the driving drum k¹.
The bent wire in its descent pulls the oscillating plate a more towards it, and this
movement can be increased or diminished according to the position of the fulcrum
of the lever b, or the angle of the bent wire 64. This movement given to the
oscillating plate takes its projecting detector wires a' clear of the ratchet or rotating
shaft c.
Instead of the wire a³ for sustaining the bent wire being carried as shown in
Figs. 7, 8, and 9, it is or may be arranged as illustrated by Fig. 15, a partial side
view, and Fig. 16, a partial front view of the detector mechanism, namely, in two
projections from the upper edge and at one end of the oscillating plate a.
The lever b may then be of the form shown, and the bent wire with a projection
to rest upon the supporting wire a³ when the lever b descends.
The threads to be "doubled" or wound are drawn from cops (as shown), see
Fig. 7, or from bobbins or swifts arranged in any ordinary manner; they each pass
through a slit in a cleaning and guide plate el over the tube e, covered with flannel
to give friction and clean the threads through the curls or hooks (a¹) in the detector
wires up to the pulley x, as shown in Fig. 7, down through the space in the adjust-
able guide on the horizontal traverse bar ³ for distributing the threads (which
bar is actuated in any ordinary manner), and then on to the bobbin j'.
When the bobbin has been stopped the attendant lifts it so that its spindle or

page_text: pivots rest in the hollow at the top of the incline guides j, and this allows it to
rotate freely to find the ends of the thread, and when tied the bobbin is put back
into the incline guides and rests upon the end of the lever b; then the attendant
lifts the lever by means of the hook 63, and holds it for a moment, and this allows
the oscillating plate a to move by its own weight against the stop e*, when it will
sustain the end of the bent wire 6, and thus the lever b, when sufficient tension
has come upon the threads to hold up the detector wires (a¹).
The oscillating plate a is constructed by preference as shown by Figs. 10 to 13,
both Figures inclusive; it consists of a flat rectangular plate a with a pivot a² at
each end.
It has three ribs a passing lengthway, which have as many grooves cut across
them as there are to be detector wires a¹ carried by the plate. Each of these wires
ais bent as shown in Fig. 12, and when all the detector wires are placed in their
slots a thin plate or cover a³ is slided into grooves or notches in projections at
each end.
The bend ax in each wire limits its movement up and down, and prevents it
from turning.
In the modification shown on the right hand side of Figs. 7, 8, and 9 the spindle
of the bobbin on which the threads are being wound is carried in a frame ³ that
can oscillate on a rod j passing from end to end of the frame, which rod is supported
on brackets secured to the beam below. Each frame j³ is grooved to receive the
ends of the spindles or axis for the bobbin j¹, as shown.
The detector mechanism in this modification is similar to that shown on the left-
hand side of Figs. 8 and 9.
The fulcrum of the lever b is on a stand b' secured to the beam which extends
from end to end of the frame, and when it descends, from the absence of a thread
or threads, the bobbin is lifted away from the driving drum k¹. The attendant
then lifts the frame j³ until a prop j³ (jointed to the frame on a stud) is vertical,
and this holds the frame with the bobbin j¹ clear of the drum k to allow it to be
rotated to find the "ends," and when pieced the lever b is lifted by the hook b³, and
by this movement a projection 65 from the lever 6 pushes the lower end of the
prop j³ to one side, and allows the frame ³ to fall and bring the bobbin j' against
the driving drum k¹.
Fig. 17 is a side elevation of a combination similar, except in the detector
mechanism and its combination with the actuating lever, to that described in the
Specification of Letters Patent granted to James Horrocks, dated June 10th, 1878,
numbered 2318, and illustrated by Figures 3 and 4 of the Drawings.
The bobbin marked (b) in the said Figures, on which the threads are wound, is
carried in an oscillating frame (d), which is lifted when a thread breaks or is absent
by the lever (d2) centred on the same shaft (d') as the oscillating frame (d). One
arm of the lever d² carries the bent wire b‘.
The other parts of the detector mechanism will be understood from the letters
of reference hitherto used for those parts and. the previous description.
The oscillating frame d may, if desired, be hinged from a shaft or axis above
the drum.
Fig. 18 is a sectional elevation illustrating our improvements in doubling,
twisting, and winding. 1, framing; U, beam or bar extending the length of the
frame, having projections to carry the vertical stud on which the "draw drum" m
rotates, each drum having a bevel upon it driven by a bevel wheel on the hori-
zontal shaft m¹ passing from end to end of the frame, and geared with the main
driving shaft in any convenient manner.
On another projection from the beam or bar the fulcrum of a lever n is carried,
which has one arm that passes on one side of the draw drum m, a projection from
this arm coming under the edge of the drum so as to lift it on its stud and throw
it out of gear when the weighted end of the lever n falls. The end of this arm of
the lever n has an arm n² jointed to it to carry, the thread guide, and it can be
.

page_text: turned up to a right angle to the position in which it is shown in Fig. 18 when
the bobbin is to be removed from the spindle.
Another arm of the lever n has two branches, one to carry the bent wire b', the
other to act as a weight or to have a weight suspended upon it. The lever n is
held up by the end of the bent wire b resting upon the cross wire a³ carried on
the oscillating plate a of the detector mechanism, the arrangement of which will be
understood from the Drawings and previous description.
There is another arm of the lever n to which a vertical rod n³ is jointed that
has an adjustable fork n³ at its lower end that comes between grooves on the
boss of a warf p', which rotates upon an extension of the bolster of the spindle p;
the lower part of the warf is coned, and may be covered on its surface with leather,
and fits into a cone cup p³ fast on the spindle p.
The warf p' is driven by a band from a pulley or tin drum q, and when in the
position shown it is in contact with the cone cup p2, and is driving the spindle;
but when the weight end of the lever n falls the fork n³ lifts the warf p' upwards,
so that it rotates freely on the bolster without contact with or rubbing against the
spindle, and the spindle stops.
To cause it to stop more suddenly, if desired another fork or elastic projection is
or may be secured on the rod, to come below the cone cup p² fixed upon the
spindle, and to come in contact with the underside of the cone cup about the
time when the weight end of the lever n has descended to its lowest position.
The rod n hangs vertically, and each rod for each spindle is kept towards the
spindle by a rod or bar n passing from end to end of the frame.
The threads pass from cops, bobbins, or "swifts in any suitable creel over a
rod r, each thread through the hook or curl in the detector wire, through the guide
eye ¹, round the draw drum m, through the eye in the lever n³, to the bobbin on
the spindle.
.
Fig. 19 is a side, and Fig. 20 a plan view illustrating a modification where the
draw drum m is carried on a stud placed in a horizontal position, the drum being
driven by spur toothed wheels.
When the weighted end of the lever n falls it lifts the wheel on the draw drum m
out of gear with the spur wheel on the shaft m¹.
The lever n in some cases is made to carry a stud for a pulley m* made of wood,
by preference, and the threads may pass several times round the draw drum m and
pulley m before going to the guide eye.
Fig. 21 is an illustration showing the warf p' for driving the spindle arranged
to rotate on an elongated foot step, bearing the cone p² to fit its cup, being arranged
to rotate with the spindle p, but slide up and down it, there being a pin or fixed
key in the spindle to fit key ways in the boss of the cone. The cone is lifted by
a fork n³, as shown in Fig. 18. Fig. 22 illustrates our Invention for driving the
spindle p by a fast and loose warf, when the loose warf p³ rotates on an elongation
of the bolster, as shown.
The driving band is traversed by a guide on the rod n³ from the fast warf pt
to the loose warf when the rotation of the spindle is to be stopped when a thread
breaks or is absent.
The cones on the spindle, shown in Figs. 18 and 21, may be reversed if desired;
for instance, it is obvious that the cup cone p² in Fig. 18 may be on the warf, and
the external cone fast on the spindle.
Flat discs may also be used in place of cones if desired.
We have now particularly described the nature of our said Invention, and the
modes of carrying the same into effect, and claim as our Invention,―
Firstly. The combination of an oscillating plate (a) carrying detector wires, with
a rotating ratchet or shaft (c), and a lever for stopping the bobbin on which threads
are being wound in doubling and winding machines by lifting the bobbin away
from its driving surface, or lifting a draw drum or clutch out of gear with the
driving mechanism, or traversing the driving band from a fast to a loose warf,

page_text: substantially as hereinbefore described and illustrated by Figs. 1 to 9, both inclusive,
and Fig. 17 of the Drawings.
Secondly. The several combinations and arrangements of mechanism, as
herein before described and illustrated by Figs. 1 to 17 (both inclusive) of the
Drawings.
Thirdly. The arrangement of oscillating plates (a) to carry detector wires,
whether suspended on pivots or on a rod, so that the weight of the plate will bring
it against a stop in one direction, and so that the weight of and upon the lever (b)
to be sustained will act to keep the plate against the stop, substantially as herein-
before described and illustrated by the Drawings.
Fourthly. The suspending of the oscillating plates (a) on pivots (a2), when
arranged as described in clain three.
Fifthly. The construction of oscillating plates (a) with ribs (a), and the detector
wires with a bend (ax). substantially in the manner and for the purpose
herein before described and illustrated by Figs. 10 to 13, inclusive, of the
Drawings.
Sixthly. The construction of oscillating plates (a) with a sustaining wire (a³), and
the lever (b) with an adjustable bent wire b*, or its equivalent, and so that when
the lever falls the lower part of the oscillating plate will be moved or drawn
towards the lever (b), the bent wire at its bend resting upon the sustaining wire
when the lever has descended to its lowest position, substantially as herein before
described and illustrated by the Drawings.
Seventhly. The construction of the shafts (c) for acting upon the detector wires
