IMPROVE-
MENTS IN MACHINERY FOR WINDING AND REELING YARN!
"
Our invention relates to machinery for winding and recling yarn and the object
of our Invention is to stop the machine automatically when an end of yarn
breaks.
In applying our Improvements to a winding machine we employ an intermediate
roller between the driving drum and the bobbin. The yarn to be wound passes
through a needle, connected with a "stop motion," to a traversing rod on to the
bobbin which is carried by the brake lever: the bobbin rests upon the intermediate
roller carried by brackets secured to a rail: this roller lies in contact with the
driving drum until the yarn breaks. The brake lever is supported by a bracket
secured to. the rail and it carries at one end a piece of leather or other suitable
material which lies near the intermediate roller and it is held out of contact with
the roller by means of a small adjustable bracket or wire which rests on the stop
motion. Below the stop motion is a revolving or oscillating shaft provided with
projections which come in contact with any needle when the yarn breaks and the
needle falls.
The operation is as follows:-The yarn passes from the cop or bobbin to the
bobbin on which it is to be wound. When an end of yarn breaks the needle falls

page_text: and the projections on the revolving or oscillating shaft come into contact with it
thus actuating the stop motion which releases the weighted brake lever, brings
the brake against the intermediate roller and stops the roller and bobbiu. The
weight of the bobbin carrier assists the action of the brake.
In a modification of our Invention we apply a stationary brake to the inter-
mediate roller the roller and bobbin are both connected to one arm carried by a
bracket fixed to the rail: a trigger or catch on this arm rests on a part of the stop
motion a spiral spring is compressed on a stud between the bracket and arm:
needles and an oscillating or revolving shaft are employed as before described.
When an end of yarn breaks the needle falls and the projections strike the
needle and cause the stop motion to act and releaso the trigger or catch: the spiral
spring acts upon the arm and brings the intermediate roller against the brake thus
stopping the roller and the bobbin.
In another modification we support the intermediate roller and bobbin in a
stationary frame carried by the rail: a short shaft or spindle (square or of other
section) has at one end a catch or trigger and at the other end a wedge which lies
under the intermediate roller: there is a compressed spiral spring on this spindle:
the trigger of the spindle hooks on to the stop motion. When an end of yarn
breaks the needle falls, the trigger is released and the spring causes the spindle and
wedge to shoot forward and raise and stop the intermediate roller and bobbin, or
the spring and wedge may be arranged to move from the drum towards the stop
motion, the action being the same as before described.
In another modification we suspend the intermediate roller and bobbin on
independent arms from one shaft: the roller lies on the driving drum and is driven
by friction the brake lever is supported in a bracket secured to the rail and the
brake is on the inner end of the lever to the outer end of the lever is attached a
stud or pin which rests on a pin connected to the stop motion.
When an end of yarn breaks, the needle falls, the stop motion releases the brake
lever, which swings and brings the brake into contact with the intermediate roller
and thus stops the roller and bobbin.
In another modification the lever is slotted and these slots form bearings for the
intermediate roller: the brake is secured to the lever below the intermediate
roller so that when the lever is moved the roller falls in the slots and is thus
brought into contact with the brake: the bobbin is carried by arms attached to the
brake lever to the end of the brake lever is attached a pin or stud which rests
on a pin connected to the stop motion and is acted upon by the needle and revolving
or oscillating shaft when an end of yarn breaks as before described.
The stop motion for the winding frame before referred to may be arranged in
various ways as follows:-
First, We fix a bracket to the underside of the front rail of the machine which
carries the oscillating or revolving shaft with projections of any suitable shape:
on the same bracket is a centre on which a lever is placed: the lower part is a
weight and on the upper part is a wire or shaft on which the brake lever rests and
placed in a line with this wire or shaft is another wire or shaft against which the
needles are pressed when the end breaks: the. needles are so arranged that they
fall away from the oscillating or revolving shaft of themselves after the motion is
stopped the needles may be placed in slots cut in the rail in any suitable
manner,
The operation is as follows:-The yarn in passing from the cop or bobbin to the
bobbin on which it is to be wound passes through a needle which is sustained by
the thread, but when an end breaks the needle falls and comes in contact with the
revolving or oscillating shaft which forces it against a wire fixed to the weighted
lever which takes the support from under the brake lever and allows it to fall and
stop the intermediate roller: the needles are heavier at the top portion than the
bottom so that when the oscillating or revolving shaft has forced the needles out
of the way they remain there until the end is pieced up again; slots in the rails
are so arranged that the needles can lie on the angle.

page_text: Secondly. In another variation of our motion we have a weighted lever secured
to a shaft with a projecting arm at each end which holds a shaft: above this is a
shaft the upper portion of which forms a knife-edge and upon this are a number
of weighted levers, one for each end of thread to be doubled: into this are screwed
wires with eyelets for the passage of the thread and this lever is balanced according
to the number of the thread to be doubled. There is also an oscillating or revolving
shaft with projections: at the lower end of the first mentioned lever is a step into
which fits a pin on the weighted brake lever.
The action of the motion is as follows:-When a thread breaks the weighted
lever with the guide wire working on the knife edge falls upon a shaft connecting
the two arms of the first mentioned weighted lever and being caught by the
oscillating shaft is depressed thereby, the act of depression taking the square step
on the weighted lever from under the pin of the brake lever and thereby allowing
the brake lever to act..
Thirdly. In another variation of our motion we have a kind of swing frame
carrying a shaft at its upper end and swivelled in the centre. On this upper shaft
rests a bracket or pin in connection with the brake lever. Above this and working
freely in small holes in a slotted plate are wires with an eyelet at the top and with
knees bent in the wire to prevent them pulling up through or dropping down through
the small holes in the plate. These wires must be of the strength and weight
necessary for the numbers of yarn that are being doubled. There is also a shaft
either revolving or oscillating with the usual projections upon it.
The action is this:-When an end breaks the needle or wire previously sustained
by the tension thread drops and is pressed by the projections on the shaft against
the wire or shaft at the top of the swing frame. This allows the wire or pin ou
the weighted brake lever to slip over the surface of the shaft, downward, thereby
actuating the brake, and the needle in the meantime, by its own weight falls.
backward away from the oscillating shaft. The knees as before stated prevent the
wire drawing too high or falling too low.
Fourthly. In another variation of our Invention the needles pass through a
thin plate with holes as above described and the swing frame is hinged from the
top and the wire on which the brake lever rests is at the bottom. The shaft that
crosses and upon which the needles are pressed when an end is broken is between
the upper and lower shafts of the swing frame, the needles working same as before
described.
This stop motion may be varied in many ways to suit the different modifications
of our Invention hereinbefore described.
Our improvements in reeling machines are particularly applicable to Coleby's
machines and consists in applying a stop motion to the "swift" when an end of
yarn breaks.
In applying our Invention to a reeling machine we employ a shell drag board
provided with a stud at each end on which it is free to turn: one of these studs
is connected to the "knocking-off" motion of the machine in any convenient
manner.
A thread guide is fixed in one end of a weighted lever which is free to swing on
a stud fixed to the frame. A revolving shaft with one or more vanes or projections
strikes this lever when an end of yarn breaks.
The yarn passes from the cop or bobbin over the shell drag board through the
thread guide on to the "swift": when an end breaks the thread guide is released
and swings so that the vanes on the revolving shaft strike the weighted lever and
bring it against the shell drag board and cause the latter to turn sufficiently to put
the "knocking-off" or stop motion into action and thus stop the "swift."

MENTS IN MACHINERY FOR WINDING AND REELING YARN
">
Our invention relates to machinery for winding and reeling yarn and the object
of our Invention is to stop a bobbin or swift of the machine automatically when an
end of yarn breaks.
And in order that our Invention may be fully understood and readily carried
into effect we will proceed to describe the accompanying six Sheets of drawings
reference being had to the figures and letters marked thereon.
In applying our Improvements to a winding machine, parts of which are shown
on Figs. 1 and 2, we employ an intermediate roller a between the driving drum b
and the bobbin c: The yarn to be wound passes through a needle d, connected
with a "stop motion," to a traversing rod c, on to the bobbin c which is carried by
movable arins f1 connected to the brake lever f: the bobbin rests upon the inter-
mediate roller a carried by brackets a secured to the rail g: this roller lies in
contact with the driving drum b until the yarn breaks.
The brake lever is supported by a bracket a¹ secured to the rail g and it carries
at one end a piece of leather or other suitable material which lies near the inter-
mediate rollera, and it is held out of contact with the roller by means of a small
adjustable bracket or wire h, which rests on the stop motion. Below the stop
motion is a revolving or oscillating wing shaft j, which comes in contact with any
needle when the yarn breaks and the needle falls.
'
The operation is as follows:-The yarn passes from the cop or bobbin / to the
bobbin c on which it is to be wound. When an end of yarn breaks the needle d
falls and the projections on the revolving or oscillating winged shaft j, come into
contact with it, thus actuating the stop motion: the wing shaft presses against
the fallen needle d and by it moves the cross bar at the end of a sliding bar l'
on which is a spiral spring so that the bracket i on the bar is traversed far
enough to allow the pin or adjustable bracket h (on the lever f) to fall into a hole
in it and keep the spring compressed and thus allow the brake lever to lift the
intermediate roller a and stop the bobbin c: the weight of the bobbin carrier fi
assists the action of the brake. We make the needle d (shown enlarged on Sheet 2
Fig. 3) with a knee which falls on to an incline n in the needle box and when the
spring is compressed the needle moves down the incline out of contact with the
wing shaft j.
In another modification of our Invention illustrated by Figs. 3 and 4, we apply
a stationary brake to the intermediate roller a the roller a and bobbin care both
connected to a lever o, pivoted at o³ to a bracket of fixed to the rail g: we connect
the bar to a trigger or lever p, pivoted on a part of the needle box, resting
against a projection o on the lever o: a spiral spring o¹ is compressed on a stud
between the rail g and arın or lever o. Needles d and a wing shaft j are employed
as before described.
Fig. 3 shows the form of needle we prefer to use.
The knee at the middle of
the needle guides it, when it falls, down the incline n, in the needle box out of
reach of the wing shaft. We place a sliding plate n¹ secured by a thumb screw
(see Sheet 4 Figs. 7 and 8) on top of the needle box to retain the needles in position :

page_text: the needles pass through this plate and may be changed instantly by turning the
thumb screw and sliding back the plate. When an end of yarn breaks the needle &
falls and the wing shaft j strikes the needle and lifts the trigger p off the stop
piece o: the spiral spring o' acts upon the lever o and brings the intermediate
roller a against the brake o' on the bracket o, thus stopping the roller and the
bobbin c.
In another modification of our Invention illustrated by Figs. 5 and 6 we support
the intermediate roller a and bobbin c in a stationary frame carried by the rail g:
a short shaft or spindle v (square or of other section) has at one end a catch v',
and at the other end a wedge which lies under the intermediate roller a: there
is a compressed spiral spring. on this spindle v; the catch of the spindle hooks
on to the trigger p of the stop motion,
When an end of yarn breaks the needle d falls, the wing shaft j moves the
needle and the cross bar and lever p and thus the catch is released and the
spring causes the spindle and wedge to shoot forward and raise and stop the inter-
mediate roller a and bobbin c: or the spring and wedge v² may be arranged to
move from the drum 6 towards the stop motion, the action being the same as
before described.
In another modification shown in Figs. 7 and 8 we suspend the intermediate
roller a and bobbin c on independent arms f'fs from one shaft: the roller a lies
on the driving drum b and is driven by friction: the brake lever f is supported in
a bracket, secured to the rail g and the brake is on the inner end of the lever f: to
the outer end of the lever is attached a stud or pin h which rests on a bracket i
connected to the stop motion as herein before described and as shown on Figs. 1
and 2: n is the movable plate secured by a thumb screw which retains the
needles in the needle box and allows them to be readily changed by slackening the
thumb screw and sliding back the plate.
When an end of yarn breaks, the needle d falls, the stop motion releases the
brake leverf which swings and brings the brake into contact with the intermediate
roller a, and thus stops the roller and bobbin c.
In another modification of our Invention shown on Figs. 9 and 10 we employ a
weighted lever, fitted on a shaft r¹ with a projecting arm at each end which
hold a bar . Above this is a shaft a the upper portion of which forms or may
form a knife edge and upon this shaft are a number of weighted levers 8², one for
each end of thread to be doubled: into each weighted lever a¹ is screwed a needle
or wire d' with an eyelet for the passage of the thread and this lever is balanced
according to the number of the thread to be doubled. There is also a wing shaft j.
At the lower end of the first mentioned weighted lever r is a step on which rests a
pin ffixed to the weighted brake lever f.
The action is as follows:-When a thread breaks one of the weighted levers 8'
with a guide wire d' working on the knife edge falls upon the bar / connecting the
two arms of the weighted lever rand being caught by the revolving wing shaft j is
depressed thereby, the act of depression taking the step on the weighted lever r
from under the pin f¹ of the brake lever fand thereby allowing the brake lever to .
lift the roller a from the drum b.
This stop motion may be varied in many ways to suit the different modifications
of our Invention herein before described.
Our improvements in reeling machines are particularly applicable to Coleby's
machines, and consist in applying a stop motion to the "swift" when an end of
yarn breaks.
In applying our Invention to a reeling machine as shown on Figs. 11 and 12 we
employ a shell drag board provided with a stud at each end on which it is free to
turn one of these studs is connected to the "knocking off" motion of the machine in
any convenient manner. A thread guide is fixed in one end of a weighted lever
which is free to swing on a stud fixed to the frame. A revolving wing shaft with
one or more vanes or projections strikes this lever when an end of yarn breaks.
a is the shell board, free to turn on the studs a': 6 is a finger or arm secured at

page_text: one end to one of the studs a: c is a thread guide fastened to a weighted
lever c d is the traverse guide; h is a revolving winged shaft; e is the cop or
bobbin and fis the "swift"
:
The yarn from the bobbin e passes over the drag board a, through the thread
guide cand traverse guide d to the swift f; when an end breaks the lever c' falls
into the perpendicular position and the winged shaft h, comes against the lower
part of the lever, the upper part of which strikes the shell drag board u, causes it
to turn which brings the arm b'against a catch lever g which it moves: this
lever g is connected to the ordinary clutch motion and when the lever is moved the
clutch is drawn out of gear and the swift f is stopped. The lever g is of the
ordinary construction and actuates the clutch as usual.
Having stated the nature of our Invention and described the manner of
performing the same
:
We declare that we claim.
..
1. The combination with a wing shaft j and needles d, of a sliding bar Zou which
is a projection that when a thread breaks or fails is moved and allows the brake
lever to stop the bobbin as described and as shown on Figs. 1 and 2.
2. The improved stop motion herein described and shown on Figs. 3 and 4.
