Year: 1882

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 DOUBLING.
PROVISIONAL SPECIFICATION left by the said John Horrocks and James
Horrocks at the Office of the Commissioners of Patents on the 21st September
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 DOUBLING, WINDING AND TWISTING FIBROUS YARNS
OR THREADS,"
Firstly, Our invention relates to machinery more particularly intended for
doubling and winding threads on to spools without heads, and consists in a com-
bination and arrangement of mechanism which in reference to the doubling and
winding arrangement is a modification of those for doubling and winding described
in the specification of Letters Patent granted to us and Numbered 3132 and dated
the 19th day of July 1881.
The spool without heads is rotated on a spindle carried in a lever frame, which
frame is carried in another frame hinged or jointed on the framing of the machine,
or upon a bracket secured to the framing.
The spool is pressed by a weight acting upon the frame against the front of the
friction drum which is to drive it, and the lever frame, carrying that for the spool
is held up by a jointed prop which rests against the end of an arm from the
Oscillating detector plate.
When a thread breaks or is absent the oscillating detector plate is moved, the
arm from it is lifted, the prop is allowed to slide forward by the action of the
weight of or upon the two frames and thus stops the winding by withdrawing the
spool from the surface of the friction drum.

page_text: The thread guide is formed by wire or a slit piece of metal with two inclined
horns or projections, and the threads when being wound pass upwards to and over
a bowl or pulley and then descend to the spool upon which the threads are being
wound, and the position of the spool when winding is such that the threads will
enter and remain in the slit or thread guide, as long as the spool is in the winding
position, but when it moves away from the friction drum it takes the threads or
unbroken thread out of the thread guide, but the inclines or projections from the
thread guide will guide and cause the threads of themselves to enter the thread
guide again when the spool is put back into the winding position.
For winding threads on to spools without heads a quick traverse is required and
we prefer, and our invention consists in combining with the arrangements
described, a mangle wheel where the toothed part of the wheel occupies about a
quarter of a circle-Or we use a right and left handed screw or two screws driven
in reverse directions to act upon segments of a screw nut carried on arms connected
with the traverse rod. The segments of screw nuts are made to change from one
Ecrew to the other to reverse the traverse by springs and are held in position until
the change is required at each end by a guide plate, by which arrangement if
required, the spools may be wound with bevel ends.
Secondly. Our invention relates to machinery for doubling winding and twisting,
where the winding and the twisting of the threads is stopped when a thread breaks
or is absent and consists of modifications of the arrangements described in the
specification herein before mentioned and in the specification of Letters Patent
granted to us Numbered 4278 dated October 22nd 1879.
There is a shaft from end to end of the machine with a roller or boss or spur
I wheel upon it for each spindle, and there is a frame or lever for each spindle which
carries a roller which has or may have a spur wheel on its axis, and this lever
frame for the roller is jointed on the framing of the machine or on a bracket
carried on the framing.
When the threads are being wound and twisted they pass from bobbins, each
thread through the eye of a wire in an oscillating detector plate, then round or
between the roller carried by the lever frame and the boss or roller on the
constantly rotating shaft passing from end to end of the machine, then to a guide
wire, then to the flyer and bobbin on the twisting spindle. But when a thread
breaks or is absent the frame for the roller descends and the roller is brought out
of contact with the boss on the constantly rotating shaft, or the wheel on its axis
is brought out of gear with that on this shaft and this stops the winding, at the
same time the descending frame acts upon a lever connected with the clutch or
pulley driving the spindle and thus stops the twisting.
$
The weight of the frame for the roller is sustained and it is held in the winding
and twisting position by a prop jointed to the lever frame, the end of which comes
.against the end of the arm from the oscillating detector plate.

by the said John Horrocks and James Horrocks in the Great Seal Patent
Office on the 19th March 1883.
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 DOUBLING WINDING AND TWISTING FIBROUS YARNS.
OR THREADS,"
Firstly. Our invention relates to machinery more particularly intended for
doubling and winding threads on to spools without heads, and consists in a
combination and arrangement of mechanism which in reference to the doubling
and winding arrangements is a modification of those for doubling and winding
described in the specification of Letters Patent granted to us and Numbered 3132:
and dated the 19th day of July 1881.
The spool without heads is rotated on a spindle carried in a lever frame, which
frame is carried in another frame, hinged or jointed on the framing of the machine
or upon a bracket secured to the framing.
The spool is pressed by a weight acting upon the frame against the front of the
friction drum which is to drive it, and the lever frame, carrying that for the spool
is held up. by a jointed prop which rests against the end of an arm from the
oscillating detector plate
When a thread breaks or is absent, the oscillating detector plate is moved, the
arm from it is lifted, the prop is allowed to slide forward by the action of the
weight of or upon, the two frames and thus stops the winding by withdrawing the
spool from the surface of the friction drum.
The thread guide is formed by wire or a slit piece of metal with two inclined
horns or projections, and the threads when being wound pass upwards to and over
a bowl pulley or pulleys, and then descend to the spool upon which the threads are
being wound, and the position of the spool when winding is such that the threads
will enter and remain in the slit or thread guide, as long as the spool is in the
winding position, but when it moves away from the friction drun it takes the
threads or unbroken thread out of the thread guide but the inclines or projections
from the thread guide will guide and cause the threads of themselves, to enter the
thread guide again, when the spool is put back into the winding position.
For winding threads on to spools without heads a quick traverse is required,
and we find that the ordinary heart wheel traverse motion is the best, the traverse
rod being arranged so that a projection from it will come at each end of its.
traverse, against and compress a spring near the end of its movement, the reaction:
of the springs (there being one for each end of its traverse) helping to reverse the
movement of the traverse bar with less shock.
Secondly. Our invention relates to machinery for doubling winding and
twisting, where the winding is stopped on the winding and twisting of the threads
is stopped, when a thread breaks or is absent and consists of modifications of the
arrangements described in the specification herein before mentioned and in the
specification of Letters Patent granted to us Numbered 4278 dated October 22nd
1879.
There is a shaft from end to end of the machine with a roller or boss, or spur
wheel upon it, for each spindle and there is a frame or lever for each spindle which
carries a roller which has or may have a spur wheel on its axis, and this lever
frame for the roller is jointed on the framing of the machine or on a bracket
carried on the framing.
When the threads are being wound and twisted they pass from bobbins over a

page_text: rod, each thread through the eye of a wire in an oscillating detector plate, then
round or between the roller carried by the lever frame, and the boss or roller on
the constantly rotating shaft, passing from end to end of the machine, then to a
guide wire, then to the flyer and bobbin on the twisting spindle. But when a
thread breaks, or is absent, the frame for the roller oscillates or descends and
the roller is brought out of contact with the boss on the constantly rotating
shaft, or the wheel on its axis is brought out of gear with that on this shaft,
and this stops the winding, at the same time the descending frame acts or may
act upon a lever connected with the clutch or pulley driving the spindle and this
stops the twisting.
The weight of the frame for the roller is sustained and it is held in the winding
and twisting position by a prop jointed to the lever frame, the end of which comes
against the end of the arm from the oscillating detector plate.
Fig 1 is an end sectional elevation, fig 2 a front elevation, fig 3 a plan showing
the two lever frames and other parts and fig 4 a plan showing one of the lever
frames, these figures illustrating the first part of our invention.
a represents the plate or beam which carries the parts; b the triangular shaft
constantly rotating under the ends of the detector wires carried in the plate c which
oscillates on the pivots c¹ in bearings from the beam a; c² is the projection from the
detector plate c the end of which rests upon the beam a when the detector plate
is not acted upon by the rotating shaft b. d, is a bracket secured to the beam a
this bracket carries the axis of a lever frame e the axis e' being secured in the
bracket d by a set screw d'.
This lever frame e carries an axis f for another lever frame f which has bearings
for the axis or pivots of the bobbin upon which the threads are wound.
On the axis a part g is jointed having the prop g¹ secured in it by a set
screw, the end of this prop resting against the projection c² from the detector plate c
when in the position shown in fig 1.
There is a bracket f secured to the bobbin lever frame f upon which a weight ƒ³
is or may be suspended when required to press the lever frame towards and thus
the bobbin carried by it against the surface of the driving roller h¹ which is
on a shaft h passing from end to end of the machine and rotating in suitable
bearings.
The traverse bar i is arranged to slide or move to and fro in or on suitable
bearings or supports by any ordinary traverse motion, and there is a thin bracket i¹
secured to it formed to a curve at the end to come as close to the roller h as possible
without contact.
The end of this bracket it is enlarged as shown, and has a slit formed in it for
the thread to pass through to the bobbin f.
On the traverse rod i and secured to the guide bracket ¹, there is a bent wire i²
forming two horns with a narrow space in the centre between the wires.
These horns as the traverse bar i works to and fro will come against the threads,
and lead them, when they are in a position to enter, to the central slit in the guiding
bracket i¹.
The threads being wound are drawn from bobbins or cops, arranged in any
ordinary and convenient manner, then pass over an ordinary guide rod which may
be covered with flannel or other suitable material, then each separate thread passes
through the eye of one of the drop wires c³ in the detector plate, then ascends and
passes over two light pulleys j and j' arranged to rotate freely in bearings in any
suitable bracket j² from a rail passing lengthway of the machine, then to the guide
slit in the bracket i' to the bobbin ƒ³.
.
.
In fig 1 the threads are shown by a full line x.
When a thread breaks or is absent, the detector plate c is acted upon and the
prop g' is released and passes under the projection c², the two lever frames e and f
oscillate or descend, and the projection fx on the bracket f' rests upon the upper
edge of the bracket d and the lower part of the lever frame f also rests upon the
same bracket, the bobbin f* coming to the position shown by the dotted circle f.

page_text: In this position the threads will take the direction shown by the dotted line <¹
and they will be withdrawn from the slit in the bracket but when the levers e
and fare put back to the position shown in fig I by the handle e' projecting from
the lever frame é the threads will be again guided by the horned wire to the slit
in the bracket which distributes the thread upon the bobbin f*
Fig 5 is an end sectional elevation fig 6 a front and fig 7 a back elevation
illustrating the second part of our invention.
a, is the framing a¹; the roller beam, a² the footstep spindle rail; a³ the
collar spindle rail; k the spindle; k' bobbin on the spindle; the flyer.
The spindle is arranged to be driven by a band working upon a warf that
rotates upon the exterior of a projection from the spindle collar as described in the
specification of our aforesaid Patent N° 4278 AD 1879, and this warf drives the
spindle k by a frictional or toothed clutch, as described in our said specification or
in the specification of Letters Patent granted to us N° 3132 AD 1881, but the
spindle may be driven by a band which can be traversed from a fast to a loose
pulley on the spindle.
h is a shaft passing from end to end of the machine, having bosses or rollers h¹
secured upon it at intervals.
d is a bracket secured to the beam a', which carries the pivots or axis c¹ of a
lever frame f the ends of which carry the pivots of a roller f* that rests upon the
roller h¹.
The lever frame ƒ carries the axis for the jointed prop g and g' which rests
against a projection from an oscillating detector plate, arranged as hereinbefore
described. The boss part g of the prop carries or may carry a wire curl i for
guiding the threads (x) which pass from the bobbins or copsy (as the case may be)
over a guide rod y' each thread through the eye in one of the detector wires c³
then are collected in the wire curl i then pass between the two rollers h¹ and f
then to the ordinary eye or curl k³ then to the flyer k² and lastly to the bobbin /¹
on the spindle k.
When a thread breaks or is absent the prop g¹ is released, the weight of the
roller and lever frame f causes it to fall away from the roller or boss h¹ on the
shaft h until a projection f³ from the boss of the lever frame f rests upon a
projecting stop on the bracket d.
This movement of the lever frame and roller f' stops the drawing of the threads
from the bobbins y and the delivery to the spindle k and when the spindle is to be
stopped as well, an arm f6 from the axis of the lever frame fjointed with a vertical
rod f' acts upon the clutch to slide it up the collar on which it rotates out of gear
or contact with the clutch part fast on the spindle
The rod f may be used to traverse the driving band of the spindle from a fast
to a loose pulley if desired.
The thread in some cases may be taken once or twice round the top roller f' if
desired.
By a modification, the top roller f' has or may have a spur wheel secured to one
side of it, to gear with a corresponding spur wheel, on the shaft h in place of the
boss or roller h¹.
In this modification the threads are taken once or twice round the roller f*.
The movement or oscillation of the lever frame f when a thread breaks or is
absent will cause the spur wheels to be brought out of gear, and they will be
brought into gear again when the lever frame f is moved back and the prop g' is
supporting it.
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. In doubling and winding machines the arranging of the bobbin on
which the threads are being wound, in relation to the thread and thread guiding
mechanism so that when a thread breaks or is absent, the thread or threads passing
to the bobbin will be withdrawn from the thread guide by the movement of the

page_text: bobbin away from the driving drum or surface substantially as hereinbefore
described.
Secondly In doubling and winding machines the arranging of the bobbin on
which the threads are being wound, in relation to the thread and thread guiding
mechanism so that when a thread breaks or is absent, the thread or threads passing
to the bobbin will be withdrawn from the thread guide by the movement of the
bobbin away from the driving surface and so that the threads will again enter the
thread guide when the bobbin is put back to its winding: position substantially as
herein before described.
Thirdly. The combination and arrangement of mechanism substantially as and
for the purpose hereinbefore described and illustrated by figs 1 to 4 inclusive of the
drawings
Fourthly. In doubling winding and twisting machines the combination with
detector mechanism of a roller arranged on a lever frame, so that when a thread
breaks or is absent, the weight of the roller and lever frame will cause the roller
to move away from contact with the rotary driving boss or surface or cause a
toothed wheel on the axis of the roller to come out of gear with a corresponding
wheel on the driving shaft and thus stop the winding of the thread substantially
as hereinbefore described.
Fifthly. In doubling winding and twisting machines, the combination with
detector mechanism of a roller arranged on a lever frame, so that when a thread
breaks or is absent, the weight of the roller and lever frame will cause the roller
and frame to move away from the driving surface or wheel and stop the winding
of the thread and at the same time the rotation of the spindle substantially as
herein before described.
Sixthly The combination and arrangement of mechanism substantially as and
for the purpose hereinbefore described and illustrated by figs 5 to 7 inclusive of the
drawings.
In Witness whereof we the said John Horrocks and James Horrocks have
hereunto set our hands and seals this sixteenth day of March in the
year of our Lord one thousand eight hundred and eighty three.
