page_text: LETTERS PATENT to John Horrocks and James Horrocks; of the City of
Manchester, in the County of Lancaster, Machine Makers, for an Invention
of “IMPROVEMENTS IN MACHINERY FOR DOUBLING and Winding, AND FOR
PROVISIONAL SPECIFICATION left by the said John Horrocks and James
Horrocks at the Office of the Commissioners of Patents on the 19th July
1881.
JOHN HORROCKS, and JAMES HORROCKS, of the City of Manchester, in the
County of Lancaster, Machine Makers. "IMPROVEMENTS IN MACHINERY FOR
DOUBLING AND WINDING AND FOR DOUBLING WINDING AND TWISTING FIBROUS
MATERIALS."
Firstly. Our improvements relate to those machines for doubling and winding,
commonly known as drum winding machines, similar to those described under
the second head of the Specification of Letters Patent granted to us and dated the
22nd October 1879 and numbered 4278. In the two modifications described
under the second head of the Specification of our said Letters Patent the bobbin
is lifted, or a frame carrying the bobbin is lifted when a thread breaks.
Our present improvements consist in improved combinations and arrangements.
the principal feature of which consists in so arranging the bobbin that when a
thread breaks, it does not require to be lifted out of contact with the periphery of
the driving drum, but is brought out of contact therewith, by allowing it to roll
or come away from the periphery of the driving drum by its own gravity, or its
gravity in addition to that of the frame in which it is carried and the weight
suspended upon it. By this arrangement a weight to lift the weight of the frame
and bobbin when a thread breaks is dispensed with, and thus for doubling and
winding coarse counts additional weight may be conveniently used for pressing the
bobbin upon which the threads are being wound more firmly against the driving
drum, which is an advantage with that class of threads.
The bobbin on which the threads are being wound is arranged in guides so as to
CO

page_text: be pressed and held against the periphery of the driving drum when winding, but
when a thread breaks the catch which holds the bobbin in position is liberated and
the periphery of the bobbin rolls or comes upon a stationary surface or incline,
which supports it and arrests its rotary momentum.
The bobbin is placed as usual on a spindle having its ends in guides on an
oscillating frame which is arranged to move with the bobbin to and from the
driving drum, the frame is or may be jointed to another oscillating frame or to
arms on a fixed fulcrum to keep the bobbin frame parallel in its movements, or is
or may be arranged in guides to slide to and from the driving drum. Combined
with the frame for the bobbin, or with the oscillating frames or arms, is an arm, and
bent wire and oscillating detector mechanism similar to that described in the
Specification of our aforesaid Patent.
Or there are catches upon, or jointed with the bobbin frame or oscillating frame,
acted upon by the plate of the oscillating detector mechanism, or there is or may
be an arm from the plate of the oscillating detector mechanism to hold or release
the bobbin frame as required.
Combined with the frame for the bobbin there is or may be a handle to lift and
hold the frame and thus the bobbin, so that its periphery will be clear of the brake'
surface or incline upon which it rests when withdrawn from the driving drum to
allow the bobbin to be freely rotated while the end is being found and pieced.
Secondly. Our Invention relates to doubling and winding machines where the
thread is drawn off bobbins, and consists in combining our improved arrangements
of stop mechanism herein described, and also those described in the Specification
of our aforesaid Patent with means for stopping the rotary momentum of all the
bobbins of a set from which the threads are drawn, when one or more threads of
the set break in winding, by connecting the lever lifting the bobbin, or lifting the
frame carrying the bobbin, or by connecting the frame carrying the bobbin on
which the threads are being wound, by a rod or wire with a lever having a brake
surface to act upon all the bobbins of the set, and stop their rotary momentum
when one or more of the threads break in unwinding, and thus prevent slack or
waste thread.
Thirdly. Our Invention relates to improvements in driving spindles for twisting
when arranged as described under the third head of the Specification of our said
Patent.
"
Instead of the friction " cone and "
cup" we use a pin or projection in the
part corresponding to the " cone and form two teeth like ratchet teeth on opposite
sides of the part corresponding to the "cup" for the pin to catch upon.

the said John Horrocks and James Horrocks in the Great Seal Patent Office
on the 18th January 1882.
JOHN HORROCKS and JAMES HORROCKS of the City of Manchester in the
County of Lancaster, Machine. Makers. IMPROVEMENTS IN MACHINERY FOR
DOUBLING AND WINDING, AND FOR DOUBLING, WINDING AND TWISTING FIBROUS
MATERIALS."
Firstly Our improvements relate to those machines for doubling and winding
commonly known as drum winding machines, similar to those described under the
second head of the Specification of Letters Patent granted to us and dated the
22nd day of October 1879 and numbered 4278.
In the two modifications described under the second head of the Specification of
our said Letters Patent, the bobbin is lifted or a frame carrying the bobbin is lifted
when a thread breaks.
Our present improvements consist in improved combinations and arrangements,
the principal feature of which consists in so arranging the bobbin, that when a
thread breaks it does not require to be lifted out of contact with the periphery of
the driving drum, as described in our aforesaid Specification, but is brought out of
contact therewith, by allowing it to roll or come away from the periphery of the
driving drum by its own gravity, or its gravity in addition to that of the frame in
which it is carried and the weight suspended upon it.
By this arrangement a weight to lift the weight of the frame and bobbin when
a thread breaks is dispensed with,-and-thus-for--doubling-and winding coarse counts,
additional weight may be conveniently used for pressing the bobbin upon which
the threads are being wound more firmly, against the driving drum, which is an
advantage with that class of threads.
The bobbin on which the threads are being wound is arranged in guides, so as to
be pressed and held against the periphery of the driving drum, when winding, but
when a thread breaks the catch which holds the bobbin in position, is liberated,
and the periphery of the bobbin rolls or comes upon a stationary surface or incliné,
which supports it and arrests its rotary momentum, or this surface may be a lever
jointed to the frame carrying the bobbin so that when it descends, the other end of
the lever will ascend to meet the descending bobbin.
The bobbin is placed, as usual, on a spindle, having its ends in guides on an
oscillating frame which is arranged to move with the bobbin to and from the
driving drum, the frame is or may be jointed to another oscillating frame or to
arms on a fixed fulcrum to keep the bobbin frame parallel in its movements, or is
or may be arranged in guides to slide to and from the driving drum.
Combined with the frame for the bobbin, or with the oscillating frame or arins, is
an arm and bent wire, and oscillating detector mechanism, similar to that described
in the Specification of our aforesaid Patent.
Or there are catches upon, or jointed with the bobbin frame or oscillating frame,
acted upon by the plate of the oscillating detector mechanism, or there is or may

page_text: be an arm from the plate of the oscillating detector mechanism to hold or release
the bobbin frame, or an arm from it, as required.
Combined with the frame for the bobbin there is or may be a handle or catch to
lift and hold the frame, or hold the frame when lifted, and thus the bobbin so that
its periphery will be clear of the brake surface or incline upon which it, rests when
withdrawn from the driving drum to allow the bobbin to be freely rotated while
the end is being found and pieced.
Secondly, Our Invention relates to doubling and winding machines where the
thread is drawn-off bobbins, and consists in combining our improved arrangements
of step mechanishi herein described and also those described in the Specification
of our aforesaid Patent, with means for stopping the rotary momentum of all the
bobbins of a set, from which the threads are drawn, when one or more threads of
the set break in winding by connecting the lever lifting the bobbin, or lifting the
Framic carrying the bobbin, or by connecting the frame carrying the bobbin on
which the threads are being wound by a cord, rod or wire, with a lever or levers
having a brake-surface to act upon all the bobbins of the set, and stop their rotary
momentum-when one or more of the threads brenk in unwinding; and thus prevent
slack or waste thread.
Thirdly. Our Invention relates to improvements in driving spindles for twisting,
when arranged as described under the third hend of the Specification of our said
Patent.
Instead of the friction cone and cup, we use one or two pin prejections or teeth
in the part corresponding to the "cone" and form two teeth, like ratchet teeth on
opposite sides of the part corresponding to the "cup" for the pin to entch upon.

plate.
Figs. 10 and 11 are sectional views illustrating modifications of the oscillating

b
In the modification shown on the left, when facing Figs. 1 and 2, the bobbin a
on which the threads are being wound is placed in a frame a', which is jointed on
a fulcrum or axis at a² which fulcrum is carried on two arms jointed on a fulcrum
or shaft in two brackets secured to the carrier beam c. On the axis or
fulcrum there is an arm d jointed, the end of which rests upon the surface of
the beam cand against the end of an arm e¹ from the oscillating defector plate e.
To the beam can incline bracket is secured which comes close to the driving
drum but without touching it.
When in the position shown in the Figures the bobbin a is held by the frame a,
close to the periphery of the driving drum g, and is rotated thereby to wind on
the threads, but when a thread breaks or is absent, the detector wire falls and its
end comes in the way of the rotating shaft or the teeth in the bosses upon it,
and this moves the oscillating plate e, and lifts the arm e secured to it which
allows the end of the arm or prop d, to slide under the arm e¹ of the oscillating
plate (e) which thus moves the latter further away from and clear of the rotary
shaft or teeth h.
It is the weight of the bobbin a frame a¹ and weights attached to the frame, by
the wire or wires (a) which pushes against the arm or prop d and thus when the
prop is liberated the bobbin (a) and frame (a¹) descend, as the arms & then turn on
their axes, and the bobbin comes upon the fixed surface, which brings it clear
of the drum and thus arrests its momentum.
By means of a handle X (shown in peculiar dotted line in Fig. 1) which is part
of one of the arms b, the frame a¹ and bobbin (a) is forced back when required to

page_text: its winding position and this brings the prop d from under the arm e¹ from the
oscillating detector mechanism e, and allows that arm el to again take the position
resting on the beam cas shown in Figs. 1 and 2. When the frame a¹ is pushed
back a projection 63 from one or both arms will come against the edge of the
beam c when the bobbin frame (a) has been pushed back far enough.
There is a thin piece of metal i jointed on the shaft the upper end of which
will be carried forward by the cross bar a' of the frame (a) when the hobbin comes
away from the drum g, and when the frame a¹ is lifted on its axis a² to get the
bobbin clear of the brake surface f the lower heavy end of the part i falls into
the position shown in Fig. 1 resting against the edge of the beame and its upper
end comes under the cross bar a and will thus sustain the bobbin frame a¹ and
when the latter is pushed forward to come against the drum y the frame a slides
off and clear of the upper end of the part i
On the right hand side of Figs. 1 and 2 the bobbin frame a¹ is jointed to a
fulcrum a², on arms on one end of a lever or frame j, having its fulcrum
bracket from the beam c.
on a
To the fulcrum or axis a² the arm or prop d is jointed the end of which rests
upon the beam and against the end of an arm e¹ from the oscillating plate e.
C
The weight upon the bobbin frame a¹ is suspended from it by cords, wires,
chains, or connections, attached to the sides of the frame at the holes a³.
When the oscillating plate e. lifts the arm e¹ and liberates the arm or prop d, the
jointed end (a2) of the bobbin frame a and that end of the lever. frame to which
it is attached descends, and the other end of the lever frame j ascends and meets and
sustains the descending bobbin a, which is thus brought away from the driving
drum g, while its momentum is at the same time arrested.
The bobbin frame a is put back to the winding position in which it is shown in
Figs. 1 and 2 by lifting the handle a attached to or formied upon the bobbin
fraine a¹.
The bobbin frame (¹) when away from the driving drum is sustained when
required clear of the end of the lever frame by a flat piece of metal i jointed
upon the fulcrum pin a².
This piece of metal has a vertical slot in it for the joint pin a and when that
end of the lever falls the lower end of the flat piece of metal i comes and rests
upon the upper surface of the bracket k and when the bobbin frame a¹ is lifted
to get the bobbin clear of the end of the lever frame the fulcrum pin a lowers in
the slot in the part, and the upper edge of it comes under the cross bar as of the
bobbin frame and sustains it in the position into which it is lifted, and when
the bobbin a is to be put back again the cross har slides over the upper end of
the piece the fulcrum pin a rising in the slot in it at the same time.
Figs. 3 and 4 illustrate an arrangement similar to that shown on the left hand
side of Figs. 1 and 2 except that the oscillating detector mechanism is used
combined with the bent wire as described in our aforesaid Specification.
One of the arms is formed as shown to receive the bent wire the end of
which rests on the cross wire of the oscillating plate e when the bobbin a, is
winding, and when the oscillating plate (e) is moved the bent wire bf descends
and this allows the bobbin frame a and bobbin to move forward until the bobbin
rests on the bracket f.
Instead of a bent wire there is or may be a straight wire resting on a
projection from the oscillating plate e as shown by peculiar dotted lines in Fig. 3.
Fig. 5 illustrates another modification somewhat similar to that illustrated on
the left hand side of Fig. 1 except that the position of the parts are reversed, the
bobbin a being between the detector mechanism e and the fulcrum a² of the bobbin
frame a¹.
In this arrangement two bobbins are or may be wound on opposite sides of the
same drum g, but only one arrangement is illustrated on one side.
The arrangement is also equally if not more conveniently applied when only one
bobbin is wound on one drum y.

the drums (g) to carry brackets for the mechanism.

frame a¹.
One of the arms is lengthened to form a handle UX; is the brake surface upon
which the bobbin a comes when the winding is stopped.
ax are arms from the hobbin frame, on which the weights are suspended by wires
a³ to press the bobbin a against the winding drum y.`
The prop or arin d to hold the bobbin franie in the winding position is jointed
to the axis a at one side of the frame a¹, and its end rests upon the beam e and
against the end of the arm e¹ from the detector mechanism, which is at one end of
the oscillating plate e. There is a catch i hinged or jointed on a pin at one side of
the bobbin frame a¹ and this catch has a pin or projection from it that will come
against the edge of one side of the bobbin frame a and prevent its free end from
descending in relation to the bobbin frame, below the position in which it is shown
in Fig. 5. When the bobbin frame a is liberated and descends, the edge of this
catch, comes against a projection from the bracket and when the bobbin is
lifted to get it clear of the brake surface the end of this catch. comes against the
projection and thus the bobbin frame a¹ is sustained in that position, but when
the bobbin frame is moved back by the handle X the end of the catch i is slided
off the projection & leaving the bobbin frame a¹ at liberty with the bobbin resting
upon the drum g.
In place of the arrangement shown, on the left of Figs. 1 and 2, the axis a² of the
bobbin frame a' is or may be arranged in slides, or guides on each side, so that it can
slide to and from the winding drum g, while at the same time it can lift at the bobbin
end of the frame, and thus oscillate on the axis a², and there may be if desired a
bowl on each end of the axis a², to run on the guides at each side.
The prop or arm d in this modification is jointed on the axis a² as in Figs.. 1
and 2.
In the modifications illustrated by Figs. 1, 2 and 5 the arm el from the
oscillating detector plate e, rest when all the detector wires are clear of the rotating
shaft or boss upon the beam c and the pressure of the end of the prop d_holds
it so as not to move too readily until a wire drops, when-the-rotating shaft h
oscillates it and the prop or arm_d_passes-under and thus lifts the arm e¹ and
moves the oscillating plate e further away from the rotating shaft or boss h.

drop wires (only one is shown) e is a thin plate with an open slot for a winged
screw e to pass through to secure the thin plate e.
The thin plate e is shown partly broken away in Fig. 7.
In one arrangement shown on the right of Figs. 1 and 2 there is a projecting
pin es at each end of the oscillating plate e which when in its place comes under
the bearing for the pivots et at each end, upon which the plate oscillates.
This arrangement. prevents the pivots from being lifted out of their bearings
as they require to be oscillated until the pins are clear of the recesses c
in the arms from the beam c before the plates e can be removed from their
bearings.

In the modifications illustrated on the left of Figs. 1 and 2 and by Fig. 3,
is a horn ex at each end of the oscillating plate which curves under a side
projection from each bearing carrying a pivot et, so that the oscillating plate e
requires to be turned, as described in reference to the modification shown on
the right of Figs. 1 and 2 before it can be removed from its bearings.
.
Figs. 10 and 11 are cross sections showing two modified arrangements of our
oscillating detector mechanism.
In Fig. 10, there is a bar having notches in its edge to receive the detector
wires.
This bar is dropped in bearings in projections from a beam or its
equivalent, or is otherwise secured to or in the beam c or in the arms from it.

page_text: The arms from the beam a have bearings for the pivots of the oscillating plate e
the axis of which comes close under without touching the projecting side of the
har as shown, and thus serves to keep the wires from getting out of their
notches in the fixed bar .
The lower end of the oscillating plate e is formed at a right angle and holes are
made in it in a line with the notches in the bar e for the lower ends of the detector
drop wires a to pass through.
When one of the detector wires drops, its end is acted upon by the rotating shaft,
or other mechanism, and this oscillates the plate e and. the lower ends of the other.
wires, the upper ends of which swivel in the notches in the fixed bar .
The action of the prop d (see Figs. 1 and 2) upon the arm el or the action of the
bent wire or straight wire (see Fig. 3) when so arranged will give further
movement to bring the ends of the drop wires clear of the actuating mechanism.
In Fig. 11; the detector wires are arranged and held in notches in a bar e fixed
to arms from the beam e, in any convenient manner and the notches are or may be
covered to keep the wires in their places by a thin plate of secured in any convenient
manner, and there is a plate e, having pivots or otherwise arranged to oscillate
which plate at its lower edge is formed at an angle to come against the lower ends
of the wires a when in a vertical position. When a wire drops its end is acted
upon by the rotating or other mechanism and the wires are pushed against the
bent edge of the plate e which is thus oscillated and acts upon the other mechanism
for stopping by one of the methods hereinbefore explained. The notches or slots
for the wires in the lower edge of the fixed bar e are made long to allow space
for the lower ends of the wires to oscillate with the edge of the plate e; and to
bring them clear of the actuating mechanism, there is a wire or piece el connected
with the oscillating plate and extends the length of it, that will pull the ends of all
the wires further when the stop mechanism operates.
The second part of our Invention is illustrated by Fig. 12 a side sectional view,
and Fig 13 à front view. u are a series of two or more babbins on pegs or
spindles, a' in a rail-a²-from-which threads are being wound on to the same

One end of the lever b carries a bar of wood or other suitable material 12, the
edge of which has a piece of flannel or other suitable soft material ceenred to it, so
that when the weighted end 13 of the lever presses the soft material upwards
towards all the heads of the bobbins to be nefed upon, each will receive pressure
that will act as a brake to stop the rotation of the bobbins.
The weighted end of the lever bis joined by a cord or other connection with
the levers or parts of the stop mechanism for stopping the rotation of the bobbin,
upon which the threads are being wound, when a thread breaks, or is absent, so that
the weighted end 13 of the lever b, will be allowed to descend when the stop
mechanism nets to stop the winding, and allow the other end of the lever to
net upon the bobbins-u:
While the threads are being wound, the weighted end 6³ of the lever b is held up
by the cord or connection.

We have now particularly described the nature of our Invention and the manner
of carrying the same into effect and would have it known that as to the sixth claim we
are aware that oscillating plates carrying detector mechanism have been proposed to be
used by ourselves as described in our said Specification of Letters Patent No. 4278
of 1879 and by others before the date of our said Letters Patent and that by our sixth

Manchester, in the County of Lancaster, Machine Makers, for an Invention
of "IMPROVEMENTS IN MACHINERY FOR DOUBLING AND WINDING, ANd for
PROVISIONAL SPECIFICATION left by the said John Horrocks and James
Horrocks at the Office of the Commissioners of Patents on the 19th July
1881.

JOHN HORROCKS and JAMES HORROCKS, of the City of Manchester, in the
County of Lancaster, Machine Makers. "IMPROVEMENTS IN MACHINERY FOR
DOUBLING AND WINDING, AND FOR DOUBLING, WINDING, AND TWISTING FIBROUS
MATERIALS."
Firstly. Our improvements relate to those machines for doubling and winding,
commonly known as drum winding machines, similar to those described under
the second head of the Specification of Letters Patent granted to us, and dated the
22nd October 1879, and numbered 4278. In the two modifications described
under the, second head of the Specification of our said Letters Patent the bobbin
is lifted, or a frame carrying the bobbin is lifted when a thread breaks.
Our present improvements consist in improved combinations and arrangements,
the principal feature of which consists in so arranging the bobbin that when a
thread breaks it does not require to be lifted out of contact with the periphery of
the driving drum, but is brought out of contact therewith by allowing it to.roll
or come away from the periphery of the driving drum by its own gravity, or its
gravity in addition to that of the frame in which it is carried and the weight
suspended upon it. By this arrangement a weight to lift the weight of the frame
and bobbin when a thread breaks is dispensed with, and thus for doubling and
winding coarse counts additional weight may be conveniently used for pressing the
bobbin upon which the threads are being wound more firmly against the driving
drum, which is an advantage with that class of threads.
The bobbin on which the threads are being wound is arranged in guides so as to

page_text: be pressed and held against the periphery of the driving drum when winding, but
when a thread breaks the catch which holds the bobbin in position is liberated, and
the periphery of the bobbin rolls or comes upon a stationary surface or incline,
which supports it and arrests its rotary momentum.
The bobbin is placed as usual on a spindle, having its ends in guides on an
oscillating frame, which is arranged to move with the bobbin to and from the
driving drum; the frame is or may be jointed to another oscillating frame, or to
arms on a fixed fulcrum to keep the bobbin frame parallel in its movements, or is
or may be arranged in guides to slide to and from the driving drum. Combined
with the frame for the bobbin or with the oscillating frames or arms is an arm and
bent wire and oscillating detector mechanism, similar to that described in the
Specification of our aforesaid Patent.
Or there are catches upon or jointed with the bobbin frame or oscillating frame,
acted upon by the plate of the oscillating detector mechanism; or there is or may
be an arm from the plate of the oscillating detector mechanism to hold or release
the bobbin frame as required.
Combined with the frame for the bobbin there is or may be a handle to lift and
hold the frame and thus the bobbin, so that its periphery will be clear of the brake
surface or incline upon which it rests when withdrawn from the driving drum to
allow the bobbin to be freely rotated while the end is being found and pieced.
Secondly. Our Invention relates to doubling and winding machines where the
thread is drawn off bobbins, and consists in combining our improved arrangements
of stop mechanism herein described, and also those described in the Specification
of our aforesaid Patent, with means for stopping the rotary momentun of all the
bobbins of a set, from which the threads are drawn when one or more threads of
the set break in winding, by connecting the lever lifting the bobbin, or lifting the
frame carrying the bobbin, or by connecting the frame carrying the bobbin on
which the threads are being wound by a rod or wire, with a lever having a brake
surface to act upon all the bobbins of the set and stop their rotary momentum
when one or more of the threads break in unwinding, and thus prevent slack or
waste thread.
Thirdly. Our Invention relates to improvements in driving spindles for twisting
when arranged as described under the third head of the Specification of our said
Patent.
'
Instead of the friction "cone" and "cup" we use a pin or projection in the
part corresponding to the "cone," and form two teeth like ratchet teeth on opposite
sides of the part corresponding to the "cup" for the pin to catch upon.

JOHN HORROCKS and JAMES HORROCKS, of the City of Manchester, in the
County of Lancaster, Machine Makers. "IMPROVEMENTS IN MACHINERY FOR
DOUBLING AND WINDING, AND FOR DOUBLING, WINDING, AND TWISTING FIBROUS
MATERIALS."
Firstly. Our improvements relate to those machines for doubling and winding,
commonly known as drum winding machines, similar to those described under the
second head of the Specification of Letters Patent granted to us, and dated the
22nd day of October, 1879, and numbered 4278.
In the two modifications described under the second head of the Specification of
our said Letters Patent the bobbin is lifted, or a frame carrying the bobbin is lifted
when a thread breaks.
Our present improvements consist in improved combinations and arrangements,
the principal feature of which consists in so arranging the bobbin that when a
thread breaks it does not require to be lifted out of contact with the periphery of
the driving drum, as described in our aforesaid Specification, but is brought out of
contact therewith by allowing it to roll or come away from the periphery of the
driving drum by its own gravity, or its gravity in addition to that of the frame in
which it is carried, and the suspended upon it.
By this arrangement a weight to lift the weight of the frame and bobbin when
a thread breaks is dispensed with, and thus for doubling and winding coarse counts
additional weight may be conveniently used for pressing the bobbin upon which
the threads are being wound more firmly against the driving drum, which is an
advantage with that class of threads.
The bobbin on which the threads are being wound is arranged in guides so as to
be pressed and held against the periphery of the driving drum when winding, but
when a thread breaks the catch which holds the bobbin in position is liberated,
and the periphery of the bobbin rolls or comes upon a stationary surface or incline
which supports it and arrests its rotary momentuin; or this surface may be a lever
jointed to the frame carrying the bobbin, so that when it descends the other end of
the lever will ascend to meet the descending bobbin.
The bobbin is placed as usual on a spindle, having its ends in guides on an
oscillating frame which is arranged to move with the bobbin to and from the
driving drum; the frame is or may be jointed to another oscillating frame, or to
arms ou a fixed fulcrum to keep the bobbin fraine parallel in its movements, or is
or may be arranged in guides to slide to and from the driving drum.
Combined with the frame for the bobbin or with the oscillating frame or arms is
an arm and bent wire and oscillating detector mechanism similar to that described
in the Specification of our aforesaid Patent.
Or there are catches upon or jointed with the bobbin frame or oscillating frame
acted upon by the plate of the oscillating detector mechanism; or there is or may
be an arm from the plate of the oscillating detector mechanism to hold or release
the bobbin frame or an arm from it as required.
Combined with the frame for the bobbin there is or may be a handle or catch to
lift and hold the frame or hold the frame when lifted, and thus the bobbin, so that
its periphery will be clear of the brake surface or incline upon which it rests when
withdrawn from the driving drum, to allow the bobbin to be freely rotated while
the "end" is being found and pieced.
Secondly. Our Invention relates to doubling and winding machines where the,

page_text: thread is drawn off bobbins, and consists in combining our improved arrangements
of stop mechanism herein described, and also those described in the Specification
of our aforesaid Patent, with means for stopping the rotary momentum of all the
bobbins of a set from which the threads are drawn when one or more threads of
the set break in winding, by connecting the lever lifting the bobbin, or lifting the
frame carrying the bobbin, or by connecting the frame carrying the bobbin on
which the threads are being wound by a cord, rod, or wire, with a lever or levers
having a brake surface to act upon all the bobbins of the set, and stop their rotary
momentum when one or more of the threads break in unwinding; and thus prevent
Black or waste thread.
Thirdly. Our Invention relates to improvements in driving spindles for twisting,
when arranged as described under the third head of the Specification of our said
Patent.
Instead of the friction cone and cup we use one or two pin projectious or teeth
in the part corresponding to the "cone," and forin two teeth like ratchet teeth on
opposite sides of the part corresponding to the "cup" for the pin to catch upon.

Figs. 6, 7, 8, and 9 are full size views of the oscillating detector plate detached;
Fig. 6 being an edge, Fig. 7 a side, Fig. 8 an end, and Fig. 9 a cross section of the
plate.
Figs. 10 and 11 are sectional views illustrating modifications of the oscillating
plate detector mechanism.
In the modification shown on the left, when facing Figs. 1 and 2, the bobbin a
on which the threads are being wound is placed in a frame a¹ which is jointed on
a fulcrum or axis at a², which fulcruin is carried on two arms b jointed on a fulcrum
or shaft in two brackets 62 secured to the carrier beam c.. On the axis or
fulcrum a there is an arm & jointed, the end of which rests upon the surface of
the beam c, and against the end of an arm c' from the oscillating detector plate e.
To the beam can incline bracket f is secured, which comes close to the driving
drum g, but without touching it.
When in the position shown in the Figures, the bobbin a is held by the frame o¹
close to the periphery of the driving drum g, and is rotated thereby to wind on
the threads, but when a thread breaks, or is absent, the detector wire falls, and its
end comes in the way of the rotating shaft h, or the teeth in the bosses upon it,
and this moves the oscillating plate e, and lifts the arm e¹ secured to it, which
allows the end of the arm or prop to slide under the arm e¹ of the oscillating
plate (e), which thus moves the latter further away from and clear of the rotary
shaft or teeth h.
It is the weight of the bobbin a, frame a¹, and weights attached to the frame by
the wire or wires (a³) which pushes against the arm or prop d, and thus when the
prop is liberated the bobbin (a) and frame (a') descend, as the arms & then turn on
their axes b', and the bobbin comes upon the fixed surface f, which brings it clear
of the drum g, and thus arrests its momentum.
By means of a handle b* (shown in peculiar dotted line in Fig. 1), which is part
of one of the arms b, the frame (a') and bobbin (a) is forced back when required to
its winding position, and this brings the prop d from under the arm e¹ from the
oscillating detector mechanism e, and allows that arm e to again take the position,
resting on the beam c, as shown in Figs. 1 and 2. When the frame a¹ is puslied
back a projection 3 from one or both arms b will come against the edge of the
beam e when the bobbin frame (a¹) has been pushed back far enough.
There is a thin piece of metal i jointed on the shaft b', the upper end of which
will be carried forward by the cross bar a of the frame (a) when the bobbin comes
away from the drum g, and when the frame a is lifted on its axis a² to get the

page_text: bobbin clear of the brake surface f the lower heavy end of the part i falls into
the position shown in Fig. 1 resting against the edge of the beam c, and its upper
end comes under the cross bar a, and will thus sustain the bobbin frame a¹, and
when the latter is pushed forward to come against the drum g, the frame a¹ slides
off and clear of the upper end of the part i.
On the right hand side of Figs. 1 and 2 the bobbin frame a¹ is jointed to a
fulcrum a² on arms on one end of a lever or frame j, having its fulcrum j¹ on a
bracket from the beam c.
To the fulcrum or axis a² the arm or prop d is jointed, the end of which rests
upon the beam c and against the end of an arm e¹ from the oscillating plate c.
The weight upon the bobbin frame a¹ is suspended from it by cords, wires,
chains, or connections attached to the sides of the frame at the holes a³.
When the oscillating plate e lifts the arm e¹ and liberates the arm or prop d, the
jointed end (a2) of the bobbin frame a¹, and that end of the lever frame j to which
it is attached descends, and the other end of the lever frame j ascends and meets and
sustains the descending bobbin a, which is thus brought away from the driving
drum g while its momentum is at the same time arrested.
The bobbin frame a¹ is put back to the winding position in which it is shown in
Figs. 1 and 2, by lifting the handle a attached to or formed upon the bobbin
frame a¹.
The bobbin frame (a) when away from the driving drum g is sustained when
required clear of the end of the lever frame j by a flat piece of metal i jointed
upon the fulcrum pin a².
This piece of metal has a vertical slot in it for the joint pin a², and when that
end of the lever i falls, the lower end of the flat piece of metal i comes and rests
upon the upper surface of the bracket h, and when the bobbin frame a¹ is lifted
to get the bobbin clear of the end of the lever frame j, the fulcrum pin a lowers in
the slot in the part i, and the upper edge of it comes under the cross bar a³ of the
bobbin frame a¹, and sustains it in the position into which it is lifted, and when
the bobbin a is to be put back again, the cross bar a slides over the upper end of
the piece, the fulcrum pin a² rising in the slot in it at the same time.
Figs. 3 and 4 illustrate an arrangement similar to that shown on the left hand
side of Figs. 1 and 2, except that the oscillating detector. mechanism is used
combined with the bent wire, as described in our aforesaid Specification.
One of the arms 6 is formed as shown to receive the bent wire b, the end of
which rests on the cross wire e³ of the oscillating plate e when the bobbin a is
winding, and when the oscillating plate (e) is moved, the bent wire b* descends,
and this allows the bobbin frame a¹ and bobbin to move forward, until the bobbin
rests on the bracket f.
Instead of a bent wire there is or may be a straight wire 65 resting on a
projection from the oscillating plate e, as shown by peculiar dotted lines in Fig. 3.
Fig. 5 illustrates another modification, somewhat similar to that illustrated on
the left hand side of Fig. 1, except that the position of the parts are reversed, the
bobbin a being between the detector mechanism e, and the fulcrum a² of the bobbin
frame a¹.
In this arrangement two bobbins are or may be wound on opposite sides of the
same drum g, but only one arrangement is illustrated on one side.
The arrangement is also equally, if not more conveniently, applied when only one
bobbin is wound on one drum g.
In the modifications illustrated there is a beam lengthway of the machine above
the drums (g), to carry brackets b² for the mechanism.
6¹ fulcrum or axis for the arms b carrying the fulcrum or axis a² for the bobbin
frame a¹
One of the arms b is lengthened to form a handle b*. f is the brake surface upon
which the bobbin a comes when the winding is stopped.
a* are arms from the bobbin frame on which the weights are suspended by wires
a³ to press the bobbin a against the winding drum g.

page_text: The prop or arm to hold the bobbin frame in the winding position is jointed
to the axis 2 at one side of the frame a¹, and its end rests upon the beam c and
against the end of the arin e' from the detector mechanism, which is at one end of
the oscillating plate c. There is a catch i hinged or jointed on a pin at one side of
the bobbin frame a¹, and this catch has a pin or projection from it that will come
against the edge of one side of the bobbin frame a', and prevent its free end from
descending in relation to the bobbin frame below the position in which it is shown
in Fig. 5. When the bobbin frame a' is liberated and descends, the edge of this
catch comes against a projection 66 from the bracket 62, and when the bobbin is
lifted to get it clear of the brake surface f the end of this catch i comes against the
projection b, and thus the bobbin frame a¹ is sustained in that position; but when
the bobbin frame is moved back by the handle b* the end of the catch i is slided
off the projection 6%, leaving the bobbin frame a¹ at liberty with the bobbin resting
upon the drum g.
In place of the arrangement shown on the left of Figs. 1 and 2, the axis a² of the
bobbin frame a¹ is or may be arranged in slides or guides on each side, so that it can
slide to and from the winding drum g, while at the same time it can lift at the bobbin
end of the frame and thus oscillate on the axis a, and there may be if desired a
bowl on each end of the axis a² to run on the guides at each side.
The prop or arm & in this modification is jointed on the axis a², as in Figs. 1
and 2.
In the modifications illustrated by Figs. 1, 2, and 5 the arm e from the
oscillating detector plate e rest when all the detector wires are clear of the rotating
shaft or boss upon the beam c, and the pressure of the end of the prop & holds
it, so as not to move too readily until a wire drops, when the rotating shaft h
oscillates it, and the prop or arm d passes under, and thus lifts the arm e¹ and
moves the oscillating plate e further away from the rotating shaft or boss h.
Figs. 6, 7, 8 and 9 illustrate our oscillating plate as we prefer to make it. e is
the oscillating plate, et pivots at each end, e ribs for notches to hold and guide the
drop wires (only one is shown), e is a thin plate with an open slot for a winged
screw e to pass through to secure the thin plate e
The thin plate e is shown partly broken away in Fig. 7.
In one arrangement, shown on the right of Figs. 1 and 2, there is a projecting
pin e at each end of the oscillating plate e, which when in its place comes under
the bearing for the pivots et at each end upon which the plate oscillates.
This arrangement prevents the pivots e from being lifted out of their bearings,
as they require to be oscillated -until the pins are clear of the recesses c¹
in the arms from the beam c before the plates e can be removed from their
bearings.
In the modifications illustrated on the left of Figs. 1 and 2 and by Fig. 3 there
is a horn e* at each end of the oscillating plate e, which curves under a side
projection from each bearing carrying a pivot e, so that the oscillating plate e
requires to be turned as described, in reference to the modification shown on the
right of Figs. 1 and 2 before it can be removed from its bearings.
Figs. 10 and 11 are cross sections showing two modified arrangements of our
oscillating detector mechanism.
In Fig. 10 there is a bar e" having notches in its edge to receive the detector
wires x.
This bar e is dropped in bearings in projections from a beam c or its
equivalent, or is otherwise secured to or in the beain c or in the arms from it.
The arms from the beam c have bearings for the pivots of the oscillating plate e,
the axis of which comes close under without touching the projecting side of the
bar e as shown, and thus serves to keep the wires from getting out of their
notches in the fixed bar e³.
The lower end of the oscillating plate e is formed at a right angle, and holes are
made in it in a line with the notches in the bar e for the lower ends of the detector
drop wires to pass through.
When one of the detector wires drops its end is acted upon by the rotating shaft

page_text: or other mechanism, and this oscillates the plate e and the lower ends of the other
wires, the upper ends of which swivel in the notches in the fixed bar e".
The action of the prop & (see Figs. 1 and 2) upon the arm el, or the action of the
bent wire or straight wire (see Fig. 3), when so arranged will give further
movement to bring the ends of the drop wires clear of the actuating mechanism.
In Fig. 11 the detector wires are arranged and held in notches in a bar e³ fixed
to arms from the beam c in any convenient manner, and the notches are or may be
covered to keep the wires in their places by a thin plate e secured in any convenient
manner, and there is a plate e having pivots or otherwise arranged to oscillate,
which plate at its lower edge is formed at an angle to come against the lower ends
of the wires when in a vertical position. When a wire drops its end is acted
upon by the rotating or other mechanism, and the wires are pushed against the
bent edge of the plate e, which is thus oscillated and acts upon the other mechanism
for stopping by one of the methods hereinbefore explained. The notches or slots
for the wires in the lower edge of the fixed bar e are made long, to allow space
for the lower ends of the wires to oscillate with the edge of the plate c, and to
bring them clear of the actuating mechanism there is a wire or piece e¹º connected
with the oscillating plate and extends the length of it that will pull the ends of all
the wires further when the stop mechanism operates.
The second part of our Invention is illustrated by Fig. 12, a side sectional view,
and Fig. 13, a front view. a are a series of two or more bobbins on pegs or
spindles a in a rail a', from which threads are being wound on to the samo
bobbin.
b is a lever on a fulcrum in a bracket secured to the rail a³.
One end of the lever b carries a bar of wood or other suitable material b², the
edge of which has a piece of flannel or other suitable soft material secured to it, so
that when the weighted end 6 of the lever presses the soft material upwards
towards all the heads of the bobbins to be acted upon, each will receive pressure
that will act as a brake to stop the rotation of the bobbins.
The weighted end of the lever b is joined by a cord or other connection with
the levers or parts of the stop mechanism for stopping the rotation of the bobbin
upon which the threads are being wound when a thread breaks or is absent, so that
the weighted end 63 of the lever b will be allowed to descend when the stop
mechanism acts to stop the winding, and allow the other end bª of the lever b to
act upon the bobbins a.
While the threads are being wound the weighted end 69 of the lever b is held up
by the cord or connection.
The third part of our Invention is illustrated by Fig. 14. a, spindle rail; a¹, long
collar, step, or bearing, within which the spindle P rotates, and outside which the
driving pulley and boss Pl rotates.
The pulley P¹ has a clutch tooth which gears with one of two teeth in a clutch
part P* fast on the spindle.
