MENTS IN MACHINERY FOR WINDING THREAD ON BOBBINS OR SPOOLS."
This Invention has for its objects generally to improve the construction and
action of machinery for winding thread on bobbins or spools, and more particularly
to contrive or arrange certain parts so that they can be adjusted with great
facility for different sizes and forms of bobbins and spools, and different varieties of
thread.
The improved machinery comprises many new or newly arranged parts combined
with certain parts described in the Specification of Letters Patent granted to
Samuel Bash, one of the present applicants, and dated 7 April, 1875 (No. 1257).
In the improved machinery the winding spindles are arranged horizontally and
at right angles to what is herein-after termed the front framing, there being eight
such spindles in a convenient modification of the machine, although, if desired, it
may be made with more or fewer spindles.
The machine is as completely automatic as possible, the attendant having merely
to place empty spools between certain feeders, and the filled and finished spools
being delivered into a box, whilst the machine stops itself on any one thread
breaking or failing. The winding spindles are driven by means of bevil pinions
on their back ends in gear with bevil wheels on a horizontal shaft at right angles
to the spindles or parallel to the front framing. The spindles are accurately
adjusted by means of screwed centre pins, against which their back ends are held

page_text: by the pressure holding the spools on their front ends. The parallel shaft is itself
driven through bevil wheels from a shaft at right angles to the front framing, and
carried by what is herein-after termed the back framing, and which extends back-
wards from the middle of the front framing, and carries the main parts of the
driving gearing as well as the traverse motion details.
The shaft last mentioned is driven by means of one of two pulleys, arranged side
by side, and fixed on two shafts carried by the back framing, one of the shafts
being tubular for the other to pass through it, and the two pulleys, which may be
termed respectively the winding pulley and the finishing and changing pulley, are
driven alternately by the same belt from a pulley on a shaft below, which last is
the first-motion shaft of the machine, and has on it fast and loose pulleys for a
driving belt. The shaft of the finishing and changing pulley through bevil wheels
drives a cam shaft, which is carried by the back framing and is parallel to the front
framing, and the cams and wipers on this shaft actuate the various parts by which,
after each winding operation, the thread ends are fixed in nicks in the spool ends
and cut, the spools are delivered from the spindles and fresh spools are placed on
the spindles, the cam shaft finally causing the transference of the belt to the
winding pulley.
The traverse motion is actuated from the winding pulley by means of the usual
right and left screw spindle in connection with half nuts attached to a rocking
plate, arranged to some extent as described in the earlier Specification herein-before
referred to. The plate, which is above the screw spindle and nearly horizontal, is
made to rock, and put. one half nut out of gear and the other into gear by means
of a vertical rocking spindle, having arms with inclined pieces on their ends to act
on one edge of the plate, one of them on its upper side and the other on its under
side, and the vertical rocking spindle carries a double-inclined piece, which is acted
on by a similar double-inclined piece attached by means of a powerful spring to an
upper plate which is moved by the rocking plate at each end of its traverse, so as
to rock the vertical spindle and through it the rocking plate.
The upper plate has on it two inclined pieces which are adjusted to suit the
shape of the spool and especially its bevilled ends, and between these pieces there
projects up a tongue, carried or moved by the rocking plate, and at each end of its
traverse giving the movement, herein-before referred to, to the upper plate. As
the spools fill the tongue is shifted outwards to the wider parts of the space
between the inclined pieces on the upper plate, and causes the traverse motion to
lengthen correspondingly with the increasing width between the ends of the spools.
The tongue is thus moved outwards by a helical cam, which is shifted round by
means of ratchet teeth acted on by a pawl worked by the traverse motion, this
pawl being on a lever which receives its movement through a pinion gearing with
a rack moving with the traverse details. The pinion allows for the varying length
of traverse of the rack by turning against the frictional resistance of a spring,
when the lever carrying it encounters a stop which determines its proper extent of
movement.
The rocking plate and other parts in connection with the traverse motion screw
spindle are connected to a frame moving forwards and backwards in horizontal
.guides on the back framing, and connected by inclined arms to a bar at the front
framing, this bar having attached to it what may be termed the front traverse bar.
The front traverse bar is fixed to its holding bar by screws passed through vertically
elongated holes, and screws acting up against its bottom edge are provided for
adjusting it vertically. On this front traverse bar there is adjustably attached a
bracket for each spool, such bracket carrying the laying-on thread guide and other
details. Each thread guide is fixed like a lever to a short horizontal spindle
accurately adjusted by means of conical collars in a tubular bearing, which last is
itself adjustable in its socket in the bracket; and at the back end of the spindle
another arm is attached to be acted on by a finger on a horizontal rod, which is
moved by a cam to lift the thread guides off the spools at the proper times.
The helical cam of the traverse motion details carries a pin adjusted on it, so as

page_text: on the set of spools being filled to act on a rocking spindle and release a catch
holding a powerful spring, which spring acting on the belt-shifting lever shifts the
belt from the winding pulley to the finishing pulley, and at the same time causes
a brake to be applied to a pulley on the shaft which drives the winding spindles.
The belt-shifting lever is held in its new position by a second catch, and a spring
of less power than the one last referred to tends to move it back, being in due time
enabled to do so by the action of a cam or wiper on the cam shaft, which through
a bell-crank lever lifts up the more powerful spring.
Whilst the winding pulley is at rest a lever or piece, having an angular notch,
is moved in connection with the belt-shifting details, so as to act on the edge of the
rocking plate of the traverse details and set it in a central position, and at the
same time another notched piece acts on the vertical rocking spindle and sets it in
the middle position, allowing of the rocking plate being set, as described. Or the
parts may be adjusted to set the vertical rocking spindle a little to one or other
side of the middle position, which will cause the winding of the fresh set of spools
to commence in either one direction or the other accordingly. With this arrange-
ment also the winding can be made to commence at any desired part of the spool,
a piece adjustably fixed on one of the inclined arms of the traverse frame
determining the commencement of the winding by being acted on by a pin or wiper
on the cam shaft.
Several of the movements connected with the finishing of the spools are trans-
mitted from the cams to horizontal spindles, carried by the upper back part of the
front framing. Chisel-like knives jointed to the ends of arms on a rocking spindle,
and guided by having their upper ends passed through a fixed rail, form the nicks
for fixing the ends of the threads in the parts of the inner ends of the spools which
are then uppermost. Each knife on being lifted pauses before getting quite clear,
to serve as a guide for the thread being led into the nick, which is done by a
peculiar hook carried and moved by a horizontal spindle, acted on by two cams so
as to both rock and move on end. This hook moves forward and backward to
catch the thread and lay it in the nick, then downwards to depress it in the nick,
and pass it between a pair of spring clips which hold a loop of it. The hook then
moves sideways to clear the clips and then up again. A horizontal or slightly
inclined knife moves to one side and back again to cut the thread, and is made
with a sharpened notch to catch the thread on the return and insure its being cut
if not already cut.
It may also here be mentioned that by a movement derived from an incline on
the traverse bar the thread end is again cut by a spring blade on the hook after
the winding on a fresh spool has been commenced, so as to detach the end which is
caught between the end of the spool and a tube on the winding spindle, and by
being so caught insures the proper starting of the winding action..
The filled spools having had the thread ends fixed and cut, the outer centres
which held the spools against the winding spindles are moved outwards and the
spools are pushed off by the tubes on the winding spindles. The outer centres turn
freely in holders which are adjustable on a plate running along the front of the
machine, and which is held by horizontal rods working in guides and acted on by
levers moved from a cam or wiper on the cam shaft, the front plate being easily
adjustable on the rods to suit different lengths of spool.
The empty spools are placed by the attendant whilst the winding of the pre-
ceeding set is in progress, each between a pair of inclined plates carried by
longitudinal rods upon what may be termed a feed plate, which is moved inwards
at the proper time by horizontal rods worked from a cam or wiper on the cam'
shaft, so as to place the spools over the positions they are to occupy when being
filled. The inclined plates then open through the action of a spring and cam guides
on the rods, carrying them so as to lower the spools down to accurately adjusted
bottom supports attached to the feed plate, and the outer centres next move
inwards and press and hold the spools against the winding spindles, after which
the feed details move outwards again and the winding commences:

page_text: The threads are drawn off large bubbins or other holders, and passing over an
upper guide rod descend to and pass under a lower guide rod; each thread next
passes under a detector and over a curved plate, and between this plate and a small
weight which applies the necessary tension and keeps back snarls. Each detector
is a piece hooked on a fixed rod, and having an arm for the thread to pass under
at one side and a hook at the other. When a thread breaks or fails the weight of
the detector makes it swing or turn, so as to bring its hook in the way of a ratchet
wheel on a horizontal spindle, which is driven through a peculiar clutch and by
means of a belt and pulleys from the shaft which drives the winding spindles.
The clutch acts on the spindle by an inclined projection, which engages with a
piece attached to the spindle by a spring. When the spindle is prevented from
turning, in consequence of any of its ratchet wheels being caught by a detector,
the spring piece is forced outwards by the inclined projection and acts on a boss,
which it turns, and by a lever and liuks connecting this boss with the main belt
shifting lever stops the machine, a brake pulley on the shaft driving the winding
spindles being also simultaneously acted on."

the said Samuel Bash and Henry Levy in the Great Seal Patent Office on the
24th January 1878.

and HENRY LEVY, of Piccadilly, in the County of Middlesex, Merchant.
MENTS IN MACHINERY FOR WINDING THREAD ON BOBBINS OR SPOOLS."
Our said Invention has for its objects generally to improve the construction and
action of machinery for winding thread on bobbins or spools, and more particularly
to contrive or arrange certain parts so that they can be adjusted with great facility
for different sizes and forms of bobbins and spools, and different varieties of
thread.
Our improved machinery comprises many new or newly arranged parts combined
with certain parts described in the Specification of Letters Patent granted to
Samuel Bash, one of us, and dated 7 April, 1875 (No. 1257).
In our improved machinery the winding spindles are arranged horizontally and
at right angles to what is herein-after termed the front framing, there being eight
Buch spindles in a convenient modification, which is herein-after particularly
described, although if desired the machine may be made with more or fewer spindles.
The machine is as completely automatic as possible, the attendant having merely to
place empty spools between certain feeders, and the filled and finished spools being
delivered into a box, whilst the machine may if desired be arranged to stop itself
on any one thread breaking or failing. The winding spindles are by means of bevil
wheels driven from a shaft parallel to the front framing, and which is itself driven
through Levi wheels from a shaft at right angles to the frout framing, and carried
by what is herein-after termed the back framing, and which extends backwards
from the middle of the front framing, and carries the main parts of the driving
gearing, as well as the traverse motion details.

page_text: The shaft last mentioned is driven by a pulley, which is one of two arranged
side by side, and both fixed on shafts carried by the back framing, one shaft being
tubular for the other to pass through it; and the two pulleys, which we term respec-
tively the winding pulley and the finishing and changing pulley, are driven
alternately by the same belt from a pulley on a shaft below, which last is the first-
motion shaft of the machine, and has on it fast and loose pulleys for a driving belt.
The shaft of the finishing and changing pulley through a worm and worm wheel
drives a cam shaft, which is carried partly by the back framing and partly by
brackets fixed to the back of the front framing, and is parallel to the front framing;
and cams and wipers on this shaft actuate the various parts by which, after each
winding operation, the thread ends are fixed in nicks in the spool ends and cut. The
filled spools are delivered from the spindles, and fresh spools are placed on the
spindles, the cam shaft finally causing the transference of the belt to the winding
pulley.
And in order that the parts herein-before referred to and the other details
comprised in our improved machinery may be properly understood, and our
Invention be carried into effect, we hereunto append two Sheets of explanatory
Drawings, to be herein-after referred to in particularly describing the said machinery.
In these Drawings the same reference letters and numbers are used to mark the
same or like parts wherever they are repeated.
Figure 1 of the accompanying Drawings is a general plan of a machine with
eight spindles S, made according to our Invention, and Figure 2 is a corresponding
side elevation, with the front framing F and back framing B to the right hand and
left hand sides respectively.
Figure 3 is a vertical section taken as at right angles to Figure 2, near the
outer end of the back framing B. The other Figures, which show detached
portions of the machinery, will be more conveniently referred to in the course of
the description.
The winding spindles S, which are horizontal and at right angles to the front
framing F, are driven by means of bevil pinions 1 on their back ends in gear with
bevil wheels 2 on a horizontal shaft 3 at right angles to the spindles, and parallel
to and carried by the front framing F. The spindles S are accurately adjusted by
means of screw pins 4, against which their back ends are held by the pressure,
which, as herein-after described, holds the spools A on their front ends. The
parallel shaft 3 is itself driven through bevil wheels 5 from a horizontal shaft 6 at
right angles to the front framing, and carried by the back framing B; and the
shaft 6 has fast on it a pulley P, close beside which there is a similar pulley Q fast
on a tubular shaft 7 through which the shaft 6 passes.
The two pulleys P, Q, herein-before referred to as the winding pulley and the
finishing and changing pulley respectively, are driven alternately by the same belt
D from a pulley 8 on a shaft 9 below, which last is the first-motion shaft of the
machine, and has on it fast and loose pulleys 10 for a driving belt. The shaft 7 of
the finishing and changing pulley Q has fast on it a worm 11 gearing with and
driving a worm wheel 12, fast on a cam shaft C, which is parallel to the
front framing F, and. is carried partly by the back framing B, and partly by
brackets 13 fixed to the front fraining F. A number of cams and wipers on the
shaft C actuate the various parts by which, after each winding operation, the thread
ends are fixed in nicks in the spool ends and cut. The spools A are delivered
from the spindles S, and fresh spools a are placed on the spindles, the cam shaft O
finally causing the transference of the belt D to the winding pulley P.
The traverse motion is actuated from the winding pulley P, a spur wheel 14 fast
to that pulley or on the same shaft driving a pinion on a shaft 15, which by spur
wheels or pinions 16 drives the usual right-and-left screw spindle 17, the wheels 16
being changeable to suit different sizes of thread. Two half nuts 18, 19, arranged
to engage alternately with the screw spindle 17, and which, with other details, are
shown enlarged in Figures 4 and 5, are attached to a rocking plate 20, which is

page_text: fixed on a spindle 21, capable of moving backwards and forwards in guide eyes in
the framing.
The rocking plate 20 and parts in connection with it are arranged to some
extent as in the earlier Specification herein-before referred to. The plate 20, which
is above the screw spindle 17, and nearly horizontal, is made to rock and put one
half nut 18 out of gear, and the other 19 into gear by means of a vertical rocking
spindle 22, having arms 23 with inclined pieces on their ends to act on one edge of
the plate 20, one of them on its upper side, and the other on its under side; and
the vertical rocking spindle 22 carries a double-inclined piece 24, which is acted on
by a similar double-inclined piece 25 attached by means of a powerful spring 26
to an upper plate 27, which is moved by the rocking plate 20 at each end of its
traverse, so as to rock the vertical spindle 22, and through it the rocking
plate 20.
The upper plate 27 has on it two inclined pieces 28, which are adjusted to suit
the shape of the spool A, and especially its bevilled ends; and between these
pieces 28 there projects up a tongue 29 moved by the rocking plate 20, and at.
each end of its traverse giving the movement, herein-before referred to, to the upper
plate 27. As the spools A fill, the tongue 29 is shifted outwards to the wider parts
of the space between the inclined pieces 28 on the upper plate 27, and causes the
traverse motion to lengthen correspondingly with the increasing width between
the ends of the spools. The tongue 29 is thus moved outwards by a helical cam 30
on a wheel 31, which is carried on a stud, and is shifted round by means of ratchet
teeth acted on by a pawl 32 worked by the traverse motion; these parts and others
in connection with them being best seen in Figure 6, which is an elevation corre-
sponding to the left-hand side of Figure 3.
The pawl 32 is on a lever connected by a screw bolt to a piece projecting from
the traverse frame 36 (herein-after described), the bolt being passed through a slot
but held by friction only, so that whilst the pawl lever 32 is limited in its movements
by stops, the connection accomodates itself to the varying traverse of the frame 36.
The helical cam piece 30 can be adjusted on its wheel 31, or different cam pieces
can be fixed on that wheel to suit different kinds of thread or forms of spool. The
part acted on by the helical cam 30 is a bent plate 33, T shaped in plan, with the
outer end of its leg working in a guide slot in a small bracket 34, fixed on the stud
which carries the wheel 31, and with the ends of the cross part working in
minor frame pieces fixed on the back framing B, and carrying other parts of the
traverse motion. The plate 33 is pressed inwards by a spring 35, so that a
projection formed or fixed on the under side of it may, bear against the helical cam
piece 30; and the cross part of the same plate 33 is formed with a slot to allow of
the traversing motion of the piece 29, the upper part of which is the tongue working
between the bevilled plates 28. The tongue piece 29 projecting down through the
slot in the plate 33 has its bottom end entered into a transverse slot in the
rocking plate 20, and thus whilst the rocking plate 20 imparts its traversing motion
to the tongue piece 29 it allows it to be moved outwards by the T plate 33, and the
slot in the latter allows the tongue piece 29 to traverse.
The spindle 21 of the rocking plate 20 has fixed to its inner end a horizontal
frame 36 formed with inclined side arms which transmit the forward and backward
traverse motion to a horizontal bar 37 at the front framing F, and beneath the
outer ends of the winding spindles S. The actual front traverse bar is a bar 38
attached to the bar 37 by horizontal screw pins entered through vertically elongated
holes, and vertical screw pins acting up against its bottom edge are tapped through
small brackets fixed to the holding bar 37, so that it can be adjusted vertically with
great accuracy.
The last-mentioned details are best seen in Figure 8, which is a partial vertical
section as at right angles to the front of the machine, Figure 9 being a front elevation
of some of the same parts. The front bar 37 of the traverse frame has fixed to it
near each end and at right angles to it, an angle-iron 36, ƒ (Figure 8), which;

page_text: working in a grooved support g fixed to the framing F, thereby supports and guides
the front part of the traverse frame in its forward and backward movement. On
the front traverse bar 38, there is adjustably attached a bracket 39 (supposed
broken away in Figure 8) for each winding spindle S, each such bracket carrying
the laying-on thread guide 40, and other details. Each thread guide 40 is fixed
like a lever to a short horizontal spindle 41 shown in a separate sectional view,
Figure 10, this spindle being accurately adjusted by means of conical collars in a
tubular bearing, which last is adjustable in its socket formed in the bracket 39. On
the thread guide spindle 41, there is also fixed a lever 42, which is connected to
parts for applying suitable pressure to the thread guides 40, and for lifting them off
the spools A at the proper times. Each lever 42 is connected by a link 43,
made with a right-and-left screw coupling to admit of accurate adjustment to a
slotted block 44 fixed on a horizontal bar 45, and this bar 45 is moved for
lifting off the thread guides 40 by a lever 46, which as is shown in Figure 11 (a
vertical section parallel to Figure 8, but reversed), is on a horizontal shaft 47, having
at its inner end a short lever 48, arranged to be acted on by a face cam 49 on the cam
shaft C. The bar 45 is made to apply pressure to the thread guides 40 by a
weight acting by a cord which passes over a pulley to the bar 45, but which is not
shown.
The helical cam wheel 31 (Figure 6), of the traverse motion details, carries an
adjustable stop 52 placed on it so as on the set of spools S becoming filled, to raise a
lever 53, shown by dotted lines in Figures 2 and 6. This lever 53 moves upwards
a sliding piece carried by a lever 54, fixed on a rocking spindle 55, so that an
adjustable pin m carried by the traverse frame 36, will cause the rocking spindle 55
which passes across the back framing B to turn up a toe 56 on its other end and by
it lift a rod 57 (Figures 2 and 7) off a holding catch 58. This rod 57 on being
released is acted on by a powerful spring 59 which is connected to a pin on a disc 60
(or it might be a bell-crank lever) having the rod 57 jointed to another pin on it.
A horn on the rod 57 acts on a lever 61 fast on a rocking shaft 62, which at
its other end (Figure 6) has fast on it the fork lever 63 for shifting the belt I)
from the pulley P to the pulley Q. The lever 61 is held in its new position
by a second catch 64, and a spring 65 of less power than the one 59 tends to
move it back, being in due time enabled to do so by the action of a wiper
pin 66 on a disc on the cam shaft C, which through a lever 67 connected to the rod
57 lifts up the more powerful spring 59. When the rod 57 is released, an arm 74
on it (Figure 7) acts through a link and bent lever on a brake strap 75, so as to
tighten the strap on a pulley 76 fixed on the shaft 3, which drives the winding
spindles S, and thereby prevent the continuance of the winding motion through
momentum.
Whilst the winding pulley P is at rest, a lever 68 carrying an angular notched
piece, is by a rod 69 having an inclined end and acted on by a cam 70 on the shalt
C, raised to make the notched piece act on a pin 71 fixed to the vertical rocking
spindle 22 of the traverse motion details, and set it in a central position, the rocking
plate 20 being also thereby set in its middle position. With this arrangement, the
winding can be made to commence at any desired part of the spool; a piece 72
adjustably fixed on one of the inclined arms 36 of the traverse frame determining
the commencement of the winding by being acted on by a pin or wiper 73 on the
cam shaft C.
Several of the movements connected with the finishing of the spools S are trans-
mitted from cams on the shaft C to horizontal spindles carried by the upper part of
the front framing. Chisel-like knives k fixed to projections on knife bars 77
form the nicks for fixing the ends of the threads in the parts of the inner ends
of the spools S, which are then uppermost. The knife bars 77 are held and
guided by means of slots in them, through which pins are screwed, into upper
and lower horizontal frame bars 78, 79, and they are moved by means of
notched pieces formed or fixed on their inner sides, the notches being engaged
with by the ends of levers -80 on a horizontal rocking spindle 81. This rocking

page_text: spindle 81 is, as shown in Figure 12, moved by a lever 82 which is acted on
by a cam 83 on the shaft C and by a spring 84, and the cam 83 is shaped so that
each knife on being lifted pauses before getting quite clear of the spool to serve as
a guide for the thread, being led into the nick. The levers 80 are fixed on their
spindle 81 with pinching screws to admit of their being adjusted to suit various
sizes of spool or bobbin, and the knife bars 77 are pressed outwards into the proper
positions for cutting the nicks in the spool ends by springs placed between them and
the frame bar 79, such springs allowing the knives to momentarily yield inwards,
when the laying-ou thread guides 40 make their traverse movements inwards on
the filling of the spools being about completed. Each thread is acted on by a
peculiar hook b, which is carried and moved by a horizontal spindle 85 held in eyes
in the outer ends of levers 86 on a horizontal spindle 87, to which both rocking and
endways motions are imparted, and on which the levers 86 are adjustable, to suit
various sizes of spool or bobbin.
The rocking motion is imparted to the spindle 87, as shown in Figure 11, by a
lever 88 fixed on it and connected by a link 89 to a bell-crank lever 90 acted on by
an edge cam 91 on the shaft C and by a counterweight 02. The endway motion is
given to the spindle 87 by a lever 93 (Figure 12) on the front end of a short spindle
having on its back end a lever 94 acted on by a face cam 95 on the shaft C. The
spindle 85 directly carrying the hooks b has also rocking movements, which are in
part imparted to it by a lever r (Figure 13), fixed on it and acted on by the front
enlarged end of a rod t, the back end of which is forked, to rest and be guided on
the shaft C, whilst a pin on the cam 105 acts on a projection on the side of it
nearest the cam so as to cause the hook b to turn out at the proper time. The
spindle 85 is made to tend to turn the hooks b inwards by bent blade springs V
(Figure 1), which are fixed on the spindle and bear on the levers 86, carrying it.
The movement of the hooks b is further steadied and controlled by short levers w
(Figure 11), fixed on the spindle 85, and which move upon vertical guides x, when
the hooks are being lowered and raised. As soon as the thread guides 40 are raised
off the spools A, after these are filled, each hook b is turned outwards, so that its
point projects forward under the thread guide. The hook b catches the thread
between the spool and the guide, and moving back with it lays it in the nick, into
which it is guided by the knife k itself, as herein-before mentioned.
After moving
sideways a little behind the spool end (that is towards the left hand in Figure 9)
each hook 6 moves downwards, its forward projecting point carrying a loop of the
thread down through a retaining piece 96 fixed to the frame bar 79. This
retainer 96 is shown separately and enlarged in Figure 14, in plan, in front
elevation, and in sectional side elevation. It is in plan a kind of rectangular
hook, the cavity of the hook facing the frame, and being occupied by a piece
of rubber z which is fixed at its right hand edge. In moving downwards the
hook bends down the rubber z, which afterwards retains the thread on the
hook rising again; but before the hook returns upwards it first moves towards
the right hand (Figure 9), and cuts the thread between its point and the spool nick
by means of a small knife y fixed on it. The hook b next moves towards the left
hand again, and then rises entirely outside of the retainer 96, leaving in the retainer
the thread end from which that on the filled spool A has been severed. The inner
edge of the front of the retainer 96 is made sharp, so that if the thread on the spool
should not have been completely severed it will be cut by such edge when the spool
is pushed outwards off the winding spindle, such movement drawing the thread
against the sharp edge.
The filled spools A having had the thread ends fixed and cut, the tubes 100 are
moved outwards and push the spools off the winding spindles S, moving the spools
and the outer centres 99 forward together. The outer centres 99 next move further
forward, and the filled spools A then fall into a box or receptacle 101. The
tubes 100 revolve with the spindles S, and are pressed against the inner ends of the
spools A by springs 102, and they are made to push off the spools by a horizontal
bar 103 formed with indentations to embrace the tubes between collars. This

page_text: bar 103 is moved by bars 104 passing through slots in the framing and acted on by
cams 105 on the shaft C. One of the outer centres 99 is shown separately and
enlarged in a sectional view, Figure 15. Each centre is a spindle 99 fitted to turn
freely in a tubular socket or holder 106 formed or fixed on a plate or bar 107
running along the front of the machine, and an adjusting screw 108 is tapped
through the outer end of each holder 106. The plate or bar 107 is at its ends
fixed adjustably to two side bars 109, which are fitted to slide forwards and back-
wards in guides on the ends of the front framing F, and are acted upon by levers 110
moved by cams 111 on the cam shaft C. The levers 110 are forked, and pins on
the cams 111 act on the back arms, whilst the edges of the cams act on the front
arms.
The empty spools a are placed by the attendant whilst the winding of the
preceding set is in progress, each between a pair of inclined feeder plates 112,
(Figures 1, 2, 8, 16,) carried by horizontal bars 113, 114, upon what may be
termed a feed plate or bar 115; these three bars 113, 114, 115, all extending
along the entire front of the machine. The feed bar 115 is carried at its ends
by the side bars 109, and is connected by links 116 (Figure 17) to forked levers 117,
which are acted on by cams 118 on the shaft C. At the proper time the cams 118
move the feed bar 115 inwards so as to place the spools a immediately over positions
a little forward of those which they are to occupy when being filled. The inclined
plates 112 then open by reverse movements of the bars 113, 114, carrying them, and
lower the spools a down to accurately adjusted bottom supports 119 attached to the
feed bar 115, and the outer centres 99 are next carried inwards, pushing the spools
backwards to their proper positions, and by means of the conical points of the outer
centres 99 and of the conical points on the front ends of the winding spindles S,
which points enter the ends of the bores of the spools, the spools become truly
centered, whilst they are afterwards made to turn by chisel points on the ends of the
winding spindles S. The bars 113, 114, are moved reversely for opening or closing
the inclined pieces 112 by means of a plate 120 centered by a pin on one end of the
feed bar 115, to which plate they are adjustably connected on opposite sides, whilst
the plate is formed with a tongue or projection, which on the inward movement
encounters a stop pin 121 fixed to the fraining and causes the plate to turn a stop
pin 122 fixed on the bar 107, causing the plate 120 to turn back again when
moving outwards. As soon as the spools become properly held between the winding.
spindles S and the outer centres 99, the bar 115 and other feed details move out-
wards again. When the fresh spools are pushed backwards into the positions for
being filled the thread ends are caught and held between their inner ends and the
outer ends of the tubes 100, which latter are roughened to prevent the escape of the
thread ends. The surplus of each thread end is afterwards cut off by a chisel-like
knife n which works through a slot in the frame bar 79, being acted on by a
lever 97 to which two oppositely acting but unequal springs are applied, the
stronger one tending to hold back the knife and the weaker one to push it forward.
The knife n is made to operate by an adjustable screw pin 98 carried by the
traverse frame bar 38, and which by pressing back the more powerful spring enables
the other one to act.
A
One turn of the cam shaft C causes the performance of the several operations of
finishing a set of spools and of changing the filled spools for empty ones, and at the
end of its turn the cam shaft causes the re-starting of the winding operation.
pin 127 (Figure 7) on a disc on the cam shaft C tilts the catch lever 64, and releases
the lever 61, whereupon the spring 65 causes the shaft 62 (Figures 7 and 6) to turn
the fork lever 63 to shift the belt D from the pulley to the pulley P, and at the
same time an arm 128, on the lever 63, by means of a pin fixed at right angles to it,
lifts up a brake pad against the pulley Q, so as to prevent its motion continuing by
momentum. The brake pad is carried by a lever 129, centered on the framing and
indicated by dotted lines in Figure 6. Before the cam shaft C completes its opera-
tions and causes the winding to be restarted the helical cam wheel 31 (Figure 6)
of the traverse motion details is restored to its starting position. The retaining

page_text: catch lever 130 acting on the ratchet teeth of the wheel 31 is released by the action
of a pin 131 on one of the cams on the shaft C; another cam pin 132 then acts on a
lever 133 and makes it move a curved bar 134, which is jointed to it, and has at its
other end a pin 135, placed so as to act on a pin 136, fixed in the cam wheel 31.
This last-named pin 136 will during the filling of the spools have been turned over
outwards, and when the bar 134 is drawn inwards its pin 135 will by acting on the
pin 136 turn the wheel 31 back again to its starting point. A spring 137, having
one end fixed to the bottom of the bracket 34, and the other to the bar 134, draws
the latter outwards again afterwards.
A box or tray 123 is fixed to the front bar 107, to hold a number of empty spools
ready for being placed on the feeding parts by the attendant, whilst a handled rod
124 is provided for stopping and starting the machine, this rod 124 being guided
across the under part of the front framing F, and being jointed at its back end to
the fork lever 125, by which the driving belt is shifted. A treadle 126 is also
connected to the rod.124 for use when convenient.
The threads are drawn off large bobbins 138 (or it might be other holders) and
passing over an upper guide rod 139, are led over a frictional inclined surface 140,
and between that surface and elastic blades 141, the pressure of which is adjusted
by holding screws so as to impart a suitable tension to the threads and prevent
curls from passing down to the laying-on guides 40.
When a
In the case of very fine or delicate threads each thread may be led under a
detector consisting of a piece hooked on a fixed rod, and having an arm for the-
thread to pass under or over at one side and a hook at the other side.
thread breaks or fails the weight of the detector makes it swing or turn so as to
bring its hook in the way of a ratchet wheel on a horizontal spindle, which is driven
through a peculiar clutch, and by means of a belt and pulleys from the shaft (3),
which drives the winding spindles (S). The clutch acts on the spindle by an
inclined projection, which engages with a piece attached to the spindle by a spring.
When the spindle is prevented from turning in consequence of any of its ratchet
wheels being caught by a detector, the spring piece is forced outwards by the
inclined projection and act on a boss, which it turns; and by a lever and links con-
necting this boss with the main shifting lever (125) stops the machine, a brake
pulley on the shaft (3) driving the winding spindles being also simultaneously
acted on.
The winding spindles S may be driven by belts instead of the bevil-wheel gearing.
