page_text: : LETTERS PATENT to William Weild, of the City of Manchester, in
the County of Lancaster, Engineer and Machinist, for the Invention
of "IMPROVEMENTS IN MACHINERY FOR WINDING YARN OR THREAD ON
TO BOBBINS, SPOOLS, OR OTHER SIMILAR SURFACES."
Sealed the 24th May 1870, and dated the 6th January 1870.
PROVISIONAL SPECIFICATION left by the said William Weild at the
Office of the Commissioners of Patents, with his Petition, on the,
6th January 1870.
I, WILLIAM WEILD, of the City of Manchester, in the County of
Lancaster, Engineer and Machinist, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN MACHINERY FOR WINDING YARN OR
THREAD ON TO BOBBINS, SPOOLS, OR OTHER SIMILAR SURFACES," to be as
follows:-
•
My improvements are made upon machinery for the purpose above
named, for which Letters Patent were granted to me numbered 122,
and dated the 21st day of January, A.D. 1858; numbered 699, and

the 16th day of April, A.D. 1867.
Firstly. My improvements relate to a mode of adjusting the traverse
bar, which gives movement to the guides distributing the thread as it is
wound upon the bobbins or spools, so as to be able to bring the thread
guides to any part of the spool or bobbin before the winding begins, and
this part of my improvements consist in arranging the shaper slide so
that one end is held up by a cam on the shaper cam shaft until the last
layer of thread has been wound upon the spool, when it falls by its own
weight and the pressure of the oscillating tail piece upon the upper side
of the shaper, and this releases both screw nuts from the right and left
handed screw shaft leaving the traverse bar at liberty to be moved by a
pin in the side of a cam or disc on the shaper cam shaft, which pin acts
upon the end of an adjustable rod at the first movement of the shaper
cam shaft after the change of the spools has been made.
Secondly. My improvements relate to arrangements which will not
only accomplish the object of the first part of my Invention, but cause
the threads to be taken. on one side so as to be caught by the thread
fixing, cutting, and holding hooks, thus dispensing with the mechanism
hitherto solely used for that purpose, and this part of my Invention
consists in arranging the shaper slide as described under the first part
of my improvements, and in adding a lever acted on in one direction by
a spring in such manner that when the shaper slide descends the lever
will be moved to bring one part of it against the shaper, the edge of
this part will then coincide with and become a continuation of the
upper surface of the shaper, so that the tail part of the oscillating screw
nuts will be held by it in mid-stroke when slided off the shaper by the
movement of a cam upon the spool changing cam shafts, which will
cause the thread guides to pass the ends of the spools, so that the thread
can be caught by the hooks, the cam then causing the thread guides to
be placed in the proper position for winding the next set of spools. The
cam may have an adjustable part in it to be altered so as to suit
each different size of spool, or the point at which the winding is to
commence.
Thirdly. My Invention relates to an improved arrangement of the
looks for fixing, holding, and cutting the threads, and consists in
making them curved in form and in placing them on a shaft or centre,
so that each hook will be more simply actuated, and will oscillate in a

page_text: certamy between the shoulder or сонат от the spimare апа the end or
the spool.
Fourthly. My improvements relate to the combination of my Patent
self-acting headstock gearing with operating mechanism where several
heads are combined together with the axes of the winding spindles
placed parallel to each other, and my improvements consist as follows:---
The spool driving spindles are made solid and fixed as to end movement,
though they may be made to slide endways in a hollow shaft. The said
spindles are all rotated by a shaft passing from end to end of the
machine at the back. The retaining spindles or centres for each head
are fixed so as to be adjustable in a beam passing from end to end of
the machine, the two ends of the beam being connected with slides,
which recieve movement when the spools or bobbins are to be replaced
by connecting rods from arms on a shaft passing from end to end of the
machine and actuated by a cam in the headstock. The thread guide
for each head is secured upon a separate shaft, which slides through the
boss of a lever having bearings in the framing at one end, but which is
geared with the boss of the lever by a sliding key or keyway, so that
the thread guide may be moved to and from the spool by the lever, all
the levers for this purpose being connected by a bar passing from end to
end of the machine, this bar being moyed endways to lift the guides by
a cam in the headstock. The pressure may be put upon the thread
guides when winding by separate weights or springs, each separate
spring or weight acting upon a separate arm upon each thread guide
shaft, or the arms of all the shafts may be connected, and the pressure
may be applied by one weight or spring, and the same connection may
be used for lifting the thread guides. The thread guide shaft may be
connected to one beam kept parallel and actuated by any suitable
means, or each thread guide shaft may be actuated seperately by toothed
racks and wheels, or by sliding inclines from a traverse bar passing from
end to end of the machine, and receiving reciprocating movement from
a right and left handed screw, as patented by me.
The thread guide is
jointed, so that it can be turned back, being held down when winding by
a latch lever. The spools when full are pushed from each spindle by a
separate sliding bar, each bar being connected by a link with an arm on
a shaft passing from end to end of the machine and actuated by a cam.
These pushers may also be made to act upon a collar on a sliding tube
9

page_text: upon each of the spooling spindles, to draw them back to allow the
thread to get between the end of the tube and spool, the tube being
pressed forward by a spring. The thread fixing, holding, and cutting
hooks, and the levers for making the incisions in the edges of the spools
are actuated by bars passing from end to end of the machine, and
having end movement from cams in the headstock. The troughs for
carrying the empty spools are secured upon a bar passing from end to
end of the machine and actuated by a cam in the headstock. The
knives for cutting the thread against the ends of the spools when
winding are each carried by a separate arm fixed upon a shaft passing
from end to end of the machine, and having oscillating movement from
a cam on the shaper cam shaft. The knives for cutting the thread
against the ends of the spools may each be secured to the end of a lever
jointed and carried in the end of the bobbin pusher and backed by a
spring, a cam on the shaper cam shaft being used to give the pushers
a slight forward movement to bring the knives against the spools to cut
the thread, play being arranged in the cam on the changing shaft to
allow of this movement.
Fifthly. My improvements relate to arrangements for giving slow
motion to the winding mechanism during the last two or three layers
of thread. This is accomplished by employing a double clutch box
between pulleys or gearing arranged to give the quick and slow speeds.
The quick speed clutch is toothed, the slow speed clutch is formed by a
friction cone. The clutch is brought out of gear with the quick speed,
and into gear with the slow speed pulleys or gearing by a spring, when
it is permitted to act by a cam on the shaper cam shaft, and this cam
reverses the double clutch at that movement of the shaper cam shaft
which is given by the changing cam shaft just before the winding
begins.

: }
NOW KNOW YE, that I, the said William Weild, do hereby declare,
the nature of my said Invention, and in what manner the same is to.
be performed, to be particularly described and ascertained in and by
the following statement and the accompanying Drawings (that is,
to say):
My improvements are made upon machinery for the purpose above.
named for which Letters Patent were granted to ne numbered 122, and:
dated the Twenty-second day of January, in the year of our Lord One-
thousand eight hundred and fifty-eight;. numbered 699, and dated the:
Sixteenth day of March, in the year of our Lord One thousand eight:
hundred and sixty; and numbered 1128, dated the Sixteenth day of April;
in the year of our Lord One thousand eight hundred and sixty-seven.
.
Firstly. My improvements relate to arrangements for giving slow:
motion to the winding mechanism of self-acting spooling machinery
Eduring the winding of the last layers of the thread. This is accomplished:
by employing a double clutch box between pulleys or gearing arranged
to give the quick and slow speeds. The quick speed clutch is toothed,
the slow speed clutch is formed by a friction conc. The clutch is:

page_text: brought out of gear with the quick speed and into gear with the slow
speed pulleys or gearing by a spring, when it is permitted to act by a
cam on the shaper cam shaft, and this cam reverses the double clutch at
that movement of the shaper can shaft which is given by the changing
cam shaft just before the winding begins.
Secondly, My improvements relate to a mode of adjusting the traverse
bar which gives movement to the guides distributing the thread as it is
wound upon the bobbins or spools, so as to be able to bring the thread
guides to any part of the spool or bobbin before the winding begins, and
this part of my improvements consists in arranging the shaper slide so
that one end is held up by a cam on the shaper cam shaft (or on the
spool changing cam shaft) until the last layer of thread has been wound
upon the spool, when it falls by its own weight and the pressure of the
oscillating tail piece upon the upper side of the shaper, and this releases
both screw nuts from the right and left handed screw shaft, leaving the
traverse bar at liberty to be moved by a pin in the side of a cam or disc
on the shaper cam shaft, which pin acts upon the end of an adjustable
rod at the first movement of the shaper cam shaft after the change of the
spools has been made.
Thirdly. My improvements relate to arrangements which will not only
accomplish the object of the second part of my Invention, but cause the
threads to be taken on one side, so as to be caught by the thread fixing,
cutting, and holding hooks, thus dispensing with the mechanism hitherto
solely used for that purpose, and this part of my Invention consists in
arranging the shaper slide as described under the second part of my
improvements, and in adding a lever acted upon in one direction by a
spring or weight in such manner that when the shaper slide descends
the lever will be moved to bring one part of it against the shaper;
the edge of this part will then coincide with and become a continuation
of the upper surface of the shaper, so that the tail part of the oscillating
screw nuts will be held by it in mid-stroke when slided off the shaper by
the movements produced by a cam upon the spool changing cam shaft,
which will cause the thread guides to pass the ends of the spools, so that
the thread can be caught by the hooks, the cam then causing the
thread guides to be placed in the proper position for winding the next
set of spools. The cam may have an adjustable part in it to be altered
so as to suit each different size of spool or the point at which the
winding is to commence.

page_text: Fourthly. My Invention relates to an improved arrangement of the hooks.
for fixing, holding, and cutting the threads, and consists in making them
curved in form and in placing them on a shaft or centre so that each
hook will be more simply actuated and will oscillate in a curve, bringing
the threads in such a position as to be caught with more certainty
between the shoulder or collar of the spindle and the end of the spool.
.
Fifthly. My improvements relate to the combination of my Patent
self-acting headstock gearing with operating mechanism where several
heads are combined together with the axis of the winding spindles placed
side by side and parallel to each other, and my improvements consist as
follows: The spindles for the spools are made solid and fixed as to end
movement, though they may be made to slide endways in a hollow shaft.
The said spindles are all rotated by a shaft passing from end to end of
the machine at the back. The retaining spindles or centres for cach.
head are fixed, so as to be adjustable in a beam passing from end to end:
of the machine, the two ends of the beam being connected with slides.
which receive movement when the spools or bobbins are to be replaced.
by connecting rods from arms on a shaft passing from end to end of the
machine and actuated by à cam. The thread guide for each head is
secured upon a separate shaft or rod which slides through the boss of a
lever having bearings in the framing at one end, but which is geared
with the boss of the lever by a sliding key or keyway so that the thread
guide may be moved to and from the spool by the lever, all the levers for
this purpose being connected by a bar passing from end to end of the
machine, this bar being moved endway's to lift the guides by a cami in
the headstock. The pressure may be put upon the thread guides when.
winding by separate weights or springs; each separate spring or
weight acting upon a separate arm upon each thread guide shaft or the
arms of all the shafts may be connected and the pressure may be applied.
directly by one weight or spring or through a radius rod, and the same.
connection may be used for lifting the thread guides. The thread guide--
shaft may be connected to one beam kept parallel and actuated by any
suitable means, or each thread guide shaft may be actuated separately
by toothed racks and wheels, or by sliding inclines from a traverse bar
passing from end to end of the machine and receiving reciprocating
movement from a right and left handed screw as patented by me. The
thread guide is jointed so that it can be turned back, being held down
when winding by a latch lever or bolt. The spools when full are pushed

page_text: from each spindle by a separate sliding bar, each bar being connected by
a link with an arm on a shaft passing from end to end of the machine
and actuated by a cam. These pushers may also be made to act upon a
collar on a sliding tube upon each of the spooling spindles to draw them
back from the spool to allow the thread to get between the end of the tube
and spool, the tube being pressed forward against the spool by a spring.
The thread fixing, holding, and cutting hooks and the levers for making
the incissions in the edges of the spools are actuated by bars passing from
end to end of the machine and having end movement from cams in the
headstock. The troughs for carrying the empty spools are secured upon
a bar passing from end to end of the machine and actuated by a cam in
the headstock. The knives for cutting the thread against the ends of
the spools when winding are cach carried by a separate arm fixed upon a
shaft passing from end to end of the machine, and having oscillating
movement from a cam on the sharper cam shaft. The knives for cutting
the thread against the ends of the spools may each be secured to the end
of a lever jointed and carried in the end of the bobbin pusher and backed
by a spring, a cam on the shaper cam shaft being used to give the
pushers a slight forward movement to bring the knives against the spools
to cut the thread, play being arranged in the cam on the changing shaft
to allow of this movement.

The first part of my Invention is illustrated by Figs. 1 and 2; it is
also shown as applied to my improved machine according to the fifth
part of my present improvements by Figs. 11, 12, and 13. a is the
first motion shaft of the machine; a¹ is a pulley on this shaft, upon.
which a belt works that drives the pulleys 6' on the shaft b, which has
two pulleys 62 and 63 fixed upon it, which by belts 6 and 65 drive.
pulleys 6 and 6' loose on the counter shaft 68. Fast on this shaft (68).
there is a pulley 6º, upon which a belt (61) works that drives a pulley.
(c) on the shaft (c), giving motion to the winding spindles. One side.
of the pulley 6° has clutch teeth formed upon it, and one side of the.
pulley has a cone clutch formed upon it, and upon the shaft 68 a
double clutch 6" is arranged, one side to gear with the toothed clutch,
on 6º, the other side to gear with the cone clutch on . This double,

page_text: clutch can slide endways on the shaft 68; having a key or stud in it
which fits a notch in a disc 6* fast on the shaft. The double clutch is
connected with one end of a lever (612) having its fulcrum on a pin; 6¹³
is a cross stay of the framing; the other end of the lever has a pin in it,
which rests upon a disc cam 61% on the shaper cam shaft d, against which
cam 6 the pin is kept by a helical spring 61 arranged as shown.. When
the double clutch (6") is in the position shown in Fig. 1 the quick speed
pulley (66) is driving the shaft 68, and the slow speed pulley (7) is
running loose on the shaft, but when the winding, arrives at the last
layers (as arranged) the cam (61) will allow the spring (615) to pull the
double clutch out of gear with the quick speed pulley (66) and into gear
with the slow speed pulley (67), where it will remain until that movement
of the shaper cam shaft (d) occurs which starts the winding after the
change of spools has taken place, when the cam 6 again brings the
double clutch into gear with the quick speed pulley (6º).
The second part of my Invention is illustrated by Figs. 1, 2, 4, and 5,
and also as applied to the machine according to the fifth part of my
present improvements by Figs. 11, 12, and 13. e is the traverse bar;
f is the right and left handed screw shaft; e¹ is the oscillating part
which carries the partial screw nuts that gear with the screw shaft;
e2, the tail part in the oscillating piece working against the shaper (d'),
which is secured to the shaper slide bar d² that is jointed to the upper
end of the escape plate lever g; is the shaper cam, which acts upon
the pin d in the shaper slide bar (d²). To carry out this second part
of my Invention the end of the shaper slide (d2) has a projection (d³)
secured to or formed on its under side, as shown, and it is arranged so
that it can lift up and down. The projection (d³) rests upon a disc
cam de secured on the shaper cam shaft (d). This disc cam (d) is
shaped and arranged so that at the end of the last part of the movement
of the shaper cam shaft when the winding is finished the projection will
be released, and this will allow the shaper slide (d²) to fall to bring the
oscillating tail piece e² (which rests at the edge of the shaper and on its
upper side) into its mid position, when both screw nuts (d') will be out
of gear with the screw shaft (f); this allows the traverse bar (e) to be
slided to any required position upon the empty spools by a pin (d) fixed
in a disc (d) secured upon the shape cam shaft (d); this pin (8).
during that movement of the shaper cam shaft which takes place at the
conclusion of the changing of the spools comes sooner or later (às'

page_text: arranged) against the end of an adjustable rod (d) sliding in suitable
bearings, this rod being connected with an arm (a) sliding on a
stud (d) in the frame, which arm is also secured upon the traverse
bar (e). The rod (d) and pin (d³) are so adjusted that the pin will
have escaped from the end of the rod when the movement is finished.
That movement of the shaper cam shaft (d) which effects the adjustment
of the traverse bar (e) also causes the shaper slide bar (d2) to be lifted
by the cam (d) into its proper position for regulating the traverse, in
which it is retained while the machine is winding. In place of a cam de
on the shaper cam shaft one on the changing cam shaft may be
employed acting on the shaper slide bar through a rod or other suitable
connection.
The third part of my Invention is illustrated by Figs. 1, 2, 3, 4,
and 5, and also by Figs. 6 and 7, and by Figs. 11, 12, and 13. The
arrangements described for carrying out the second part of my In-
vention are employed to carry out this third part of my Invention, with
the additions and alterations herein-after described. A short shaft (h)
is mounted in the shaper headstock, having an arm (¹) upon one end
of it, which comes under the shaper slide bar (d2); the other end of the
short shaft has an arm (72) which carries an adjustable slide (½³)
arranged as shown. The last-named arm (½³) is weighted to keep the
other arm against the under side of the shaper slide bar (d2), so that
when it falls the short shaft is oscillated to bring the end of the
adjustable slide (½³) against the shaper (d¹) when it is mid position, the
top side of the shaper and the top of the adjustable slide being then on
the same level. A pin is fixed in the frame to prevent the adjustable
slide from being carried too far forward when the shaper slide bar
descends. With the arrangement above explained the oscillating tail
piece can be slided away from the edge of the shaper on to the
adjustable slide (½³). The rod (d") and pin (18) for adjusting the
traverse bar (e) may be dispensed with, and in its place a lever (h³) is
used, which is connected with the traverse bar (e) and moves upon a
fulcrum at (i). This lever (½³) is acted upon by the cam (7") on the.
changing cam shaft j as soon as the winding is completed, and the thread
guides are lifted so as to bring the thread guides into the position shown
in Fig. 6, when the hooks for cutting and fixing the thread can ascend
and catch the threads between the ends of the full spools and the thread
guides, thus dispensing with the ordinary fingers for taking the threads.

page_text: to one side. When this has been accomplished the cam (7) acts upon
the lever h³ to bring the traverse bar e back to the position required for
commencing the winding. When the changing cam shaft comes to
rest there is a gap in that part of the cam (7) that acts upon the lever,
which gap allows the lever to be moved freely to and fro by the traverse
motion. The cam (7) may be made to take the thread guides to and
from the edge of the spools, and the adjustment of the thread guides to
their winding position may be made by the rod (d1) and pin (d³), as
herein-before explained under the second head of my Invention.
The fourth part of my Invention is illustrated by Figs. 1, 2, 6, and 7,
and also shown applied in Figs. 11 and 12, also in Figs. 15 and 16. I
will first name some of the ordinary and well-known parts of my Patcnt
spooling machine.. e is the traverse bar; 18, the thread guide holder;
e, the thread guide; c², the spindle rotating the spool upon which the
thread is being wound; c, the shaft driving the winding spindles; k, the
- lever carrying the incision knife; 1, the cradle for the empty spools, and
11, the shaft by which motion is given to them; m is a stud secured in
the headstock of the winding spindle. Upon this stud an arm m³ is
mounted, having a curved hook m² secured to it, as shewn. This hook
passes between a knife m³ on one side and a spring m* on the other side,
each of which is secured to a projection m³ and me from the spindle
headstock, as shown. The curved hook m³ is actuated by a rod m
jointed with an arm m³ on the back shaft m³, which is actuated by the
cam mo on the changing cam shaft j", the lever m", rod m¹², and arm m³,
fast on the shaft m³. Instead of the curved hooks (m²) being mounted
on separate studs they may be mounted on a shaft passing along the
front in machines where the winding spindles have their axes all in a
line, as in Figs. 6 and 7. n is the sliding rod having arms upon it to
carry knives n³ for cutting the thread against the ends of the spools
when winding. The improvements herein-before mentioned have been
mostly explained in their application to my Patent self-acting spool
winding machine in which the axes of the winding spindles are all in
the same line, and the application of the improvements to the machine
in which the winding spindles are placed side by side parallel to each
other according to the fifth part of my Invention will be seen more
clearly when that part of my Invention is described.
The fifth part of my Invention is illustrated by Figs. 9 and 10, Figs.,
11 and 12. Figs. 13 and 14. Figs. 15 and 16, and by Figs. 17 and 18.

page_text: Figs. 9 and 10 show a general view of the framing and shafting. The
framing consists of three end frames with connecting longitudinal stays
and beams. *a* are the driving pulleys; a, the first motion shaft;
a', the pulley on it driving the pulleys 6' on the shaft 6; 62 and 6³, the
pulleys on this shaft, which drive the pulleys 6° and 6' on the counter
shaft; 6 and 6, the pulley which drives the winding spindles. p is
the shaft through which motion is conveyed to the changing cam
shafts j and j', the shaft j' extending from the headstock to the opposite
end of the machine; d is the shaper cam shaft; e, the traverse bar;
z, bobbins of thread placed on vertical spindles in a box ¹ fixed on the
framing, as shown; z³, the rails over which the threads pass from the
large bobbins to be wound upon the small spools, as shown, by the
line. The arrangement of the mechanism is shown more completely
in Figs. 11, 12, and 13. The belt 60 working on the pulley & drives
a pulley c¹ on a shaft c; and this shaft is geared with a shaft (c) passing
along the back of the machine. There is a level wheel on the shaft c
for each head, which drives a bevel on a stud, to which level a spur
wheel is secured that drives a spur pinion c³ on the end of the winding
spindle (c), which has bearings in the framing, as shown. End play
is taken away from each winding spindle by means of a tail pin
screw (c³) and screw collars cº. There is a separate thread guide.
rod (e) for each spooling head, and each rod is placed in bearings, so
that it can slide endways and partly rotate. The transverse bar (e) passes
from end to end of the machine in suitable bearings and cross over each
thread guide rod (5). Upon the traverse bar for each spooling head
there is a long collar (e) having a series of incline teeth or grooves in its
face, which accurately fit and gear with similar teeth in a long collar e
secured upon the thread guide rod (e³). This long collar is kept from
moving endways by an arm ea and collar.e" fast upon the rod (e),
which can turn freely in the long collar (e'), which is itself prevented
from turning by a projection from it that enters and works in a slot in
the cross framing, as shown. The arm e' upon each thread guide rod
is jointed with a rod e passing lengthway of the machine which
connects them all together, and that arm for the spooling head nearest
the headstock is jointed with one end of another rod e¹¹, the other end
of which is jointed with a lever e¹² on a stud e¹³ in the framing at that
end furthest from the headstock (see Figs. 11 and 18). To the lever e¹³
a cord or chain e" is secured, which after passing over a pulley e¹s has
the weight attached for giving the requisite pressure to the thread

page_text: guides upon the spools. The polishing pressure is obtained by a stop e
secured to the came¹8, against which an arm (e¹) comes when the
polishing is to begin at about the last layer of thread. The cam e¹
acts upon the lever e¹ to lift the thread guides when the change of
spools is to be made. The spindle q for retaining the spools upon the
winding spindles (c²) rotate in hollow studs q', and they are adjusted
endways by a tail pin screw and lock nut. These hollow studs are
secured in a beam (9²), passing in front of the machine, each end of
which beam is secured to a bar q³ sliding in the end frames, as shown,
and each of these sliding bars is connected by a link q' to an arm q³
keyed upon a shaft 2 placed in suitable bearings at the back of the
machine, and this shaft is actuated by two. duplicate cams 97, one at
each end of the shafts j¹. These cams (97) act upon levers q³ on the
shaft q, as shown best in Fig. 14. To push off the spools from the
winding spindles and perform other uses there is a separate sliding rod r
for each head placed in suitable guides, as shown, and the back end of
cach rod is connected by a link with an arm 2 on a back shaft ³, as
shown. This shaft is actuated when the spools are being changed by
a cam and. arm 75, but when winding, as explained herein-after, it is
actuated by a cam projection 75 on the shaper cam shaft (d) that acts
upon the arm 7ºº.

I now come to the mechanism which performs the operations upon
the spools and thread, commonly termed the operating parts, which are
shown full size in Figs. 15, 16, and 17. c² is the end of the winding
spindle; it has a collar cupon it, and a helical spring c³ to force the
serrated end of the collar against the end of the spool, so as to hold the
end of the thread against the end of the spool; q¹is the hollow stud
carrying the retaining spindle q; q², the beam in which the studs are
fixed;
es is the end of the thread guide rod. The thread guide e¹ is
secured to a stem piece inserted in a holder (e³) fitted on the thread.
guide rod between an arm (e19) and collar e20 secured upon the rod e³.
The thread guide holder carries a sliding bolt e¹¹, the end of which is
forced by a spring into a hole in the arm e¹ fast on the rod e³. This
locks the thread guide and thread guide rod together, but the thread
guide can be instantly released so as to lift the guide from the spool by
withdrawing the spring bolt, as the holder can then be turned on the
rodes. The incision knife (¹) is made of the form shown, and is bolted
to the side of the lever arm k, which is mounted on a stud k secured

page_text: in the frame. The same stud also carries the fulcrum of the arm or
lever m', having the curved hook m² attached to it, and this hook passes
between a knife m³ on one side and spring m* on the other side, secured
to projections m and m from the framing, as shown. The cam (k) for
the incission knife is jointed to a rod ³, which connects the arms of all
the incision levers together, and this rod is connected by a link k* with
a lever 4 centered on a stud i, the lever being actuated by the cams kon
the changing cam shaft j. The curved hook, arms, or levers m³ are
likewise connected together by a rod m², link m¹, lever m", and actuated
by a cam m. There is an empty spool trough (1) for each spooling
head mounted on a rod sliding in suitable bearings, and actuated by
a link 2, lever 1, and cam 1. The empty spool is placed in this trough,
its end against a plate 1 carried by the beam q². When the empty spool
is to be placed between the spindles the trough is brought opposite to
the retaining spindle q when it is withdrawn, and as it advances it
pushes the empty spool along the trough on to the end of the winding
spindle c², and when this is done the end of the spool will come opposite
રી gap in the sides of the trough (1), which may then be drawn back, as
shown in Fig. 17, into the position which it occupies when the machine
is winding, in which position it is shown in Fig. 16... is the end of the
rod or bar which acts to push the full spool from the spindle (c³); its end
is forked to pass on each side of the spindle, and it acts to pull back the
sliding serrated collar (c) from the end of the spool into the position.
shown in Fig. 16, to allow the thread to get in front of the serrations,
when the thread is drawn down by the curved hook (m²). This rod 1
also carries a small knife (n²) to cut the thread when winding against the
end of the spool. This knife is secured by a screw to the end of a bent.
lever n', having its fulcrum at n³; the lever is acted upon by a flat
spring n to force the knife forward until the lever comes against the
back of the fork on the end of the rod, as shown. This spring n' has
sufficient force to press the knife forward to cut when winding, but it
will allow the knife to give way when the forked end of the rod () is
pressed forward to push the spool off the spindle..
By means of the diagram, Fig. 29, I shall explain the form of the
cams and their relative times of action. The point marked 0 and 360
represent the same point of the cams, and the figures upon the diagram
are angular degrees of revolution. The spool changing cams all stand
at 0 or 360 while the machine is winding. When the machine stops

page_text: •
winding the spool changing. cams begin to rotate. The cam e¹s causes a
"dwell" from 0 to 20, and then gives the movement that lifts the thread
guides away from the spools from 20 to 40, then causes a "dwell" from
40 to 320, and a movement that lowers the guides again from 320 to 340,
and another "dwell" from 340 to 360. The incision knife cam k is made
to cause a "dwell" from 0 to 20 to give the movement to make the in-
cision from 20 to 40, and to gradually lift from 40 to 130, and to "dwell
from 130 to 360. The cam for moving the traverse bar has a suffi-
ciently wide gap in it when standing for the winding to allow the lever (/³)
to be freely moved by the traverse bar (e). This cam causes a "dwell"
from 0 to 40, then causes the thread guide to move to one side, so that
the thread can be caught by the hooks from 40 to 80, then causes a dwell
from 80 to 250, produces the movement to place the guides in the proper
position to start winding from 250 to 280, and dwells from 280 to 360.
The hook cam m¹ causes a dwell from 0 to 40, gives the lift to catch the
thread from 40 to 80, and causes the descent to take the thread to the
knife and spring nipper from 80 to 130, and causes a dwell from 130
to 270, and then gives the partial ascent to release the thread from the
nipper from 270 to 300, and dwells from 300 to 360. The cam q² causes
a dwell from 0 to 110; gives movement to withdraw the retaining spindles
from 110 to 150, causes another dwell from 150 to 220, and gives the
movement to push the spool on to the winding spindle from 220 to 260,
and then causes a dwell from 260 to 360. The cam 74 causes a dwell
from 0 to 50, gives movement to withdraw the collar (c) from the spool
from 50 to 70, causes a dwell from 70 to 130, and then gives the move-
ment to push the spool off the winding spindle from 130 to 170, causes
a dwell from 170 to 190, and then gives the movement to draw back
from 190 to 220, and causes a dwell from 220 to 360. In this cam there
is play or a gap at 360 to allow a cam 75 on the shaper cam shaft to
push the knives (n²) against the end of the spools when winding. The
cam causes a dwell from 0 to 170, produces the movement to bring
the spool trough or cradle (2) opposite the winding spindle (c²) from
170 to 220, then causes a dwell from 220 to 270 to allow the spool to
be pushed on to the winding spindle, then gives the movement to push
back the trough to its position when the machine is winding from 270
to 320, and causes a dwell from 320 to 360.

to fit the groove.
Figs. 23, 24, and 25 show another alternative method where a toothed
rack secured on the traverse bar (e) gears with a wheel on a short
vertical shaft (e*) which has another wheel upon it that gears with a rack
on the thread guide rod (e³). This last arrangement is applicable also to
the alternative arrangement of the operating parts illustrated full size by
Figs. 26, 27, and 28. c² is the winding spindle; r, the bar for pushing
the full spool off the spindle acting simply for this purpose; n, a shaft
passing lengthway of machine having an arm n' upon it for cach head
which carries a knife n² to cut the threads against the end of the spool;
this shaft n receives movement from a drum cam projection on the
shaper cam shaft d; m is a hook with knife and spring nipper of ordinary
construction, and in the same bracket there is a shaft carrying a
finger for taking the thread to one side, so as to be caught by the
hook. The shaft (t) has a wheel 12 on it which gears with a rack on the
end of a rod t sliding in suitable bearings, being connected by a link to
a lever on a shaft at the back of the machine, there being a separate link
lever and rod for each spooling head. The shaft at the back of the
machine receives movement at the proper time from a cam on the spool
changing shaft j'; is the incision lever on a stud k², and m* is the lever
on a stud for actuating the hook m². Both the levers k and m¹ for the
incission and hooks are actuated by rods, as in Figs. 11 and 12. The
thread guide rods e slide at the front end through the boss of a lever e*
having a bearing in the framing and capable of oscillating but not
moving endways. The lever e* and thread guide rod are connected by
a-sliding key, and these levers e* (there being one for each head) are all
connected together by the rod (e²²) jointed with a lever and cam by
which the thread guides can be lifted when required. The pressure may
be put upon the thread guides when winding by means of the rod e³, or
this may be done by the means explained in reference to Figs. 11, 12,
18, and 19. The thread guide holder (e³) is centred on a pin es in an
arme secured to the thread guide rod and the holder (es) is held wlien
winding by a hook e¹, latch e", centred at e" and held in position by a
flat spring e as shown. The empty spool is brought opposite to the
winding spindle by a trough or cradle jointed at * on a boss 1º, secured
on the rod P, and the trough is held vertical by a flat spring (7), as -

page_text: shown. But when the spool has been pushed onto the winding spindle
and the rod is moved backwards to its position when the machine is
winding the trough will turn upon its axis (*) till the side of the trough
is clear of the spool, when the spring (7) will again cause the trough to
assume its crect position.
