County of Lancaster, Engineer, for the Invention of "IMPROVEMENTS IN
MACHINES FOR WINDING YARN OR THREAD ON TO BOBBINS, SPOOLS, OR SIMILAR
SURFACES, PARTS OF WHICH IMPROVEMENTS ARE APPLICABLE TO SELF-ACTING
MULES AND LIKE MACHINES FOR SPINNING, DOUBLING, OR TWISTING FIBROUS
MATERIALS."
Sealed the 8th October 1867, and dated the 16th April 1867.
PROVISIONAL SPECIFICATION left by the said William Weild at the
Office of the Commissioners of Patents, with his Petition, on the
16th April 1867.
I, WILLIAM WEILD, of the City of Manchester, in the County of Lancaster,.
Engineer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINES FOR WINDING YARN OR THREAD ON TO BOBBINS, SPOOLS, OR
SIMILAR SURFACES, PARTS OF WHICH IMPROVEMENTS ARE APPLICABLE TO SELF-ACTING
MULES AND LIKE MACHINES FOR SPINNING, DOUBLING, OR TWISTING FIBROUS
MATERIALS," to be as follows :-
The improvements to be herein-after described are made upon and apply to
that machinery for which Letters Patent were granted to me numbered 699,

page_text: and dated the Sixteenth day of March, in the year of our Lord One thousand
eight hundred and sixty.
My first improvements relate to mechanism for actuating the "cam shaft"
for effecting the changes in the working of the machine, and these improve-
ments are applicable to self-acting mules and like machines where a cam shaft
is used. These improvements consists in a cone surface formed upon the side
of a wheel which is made to rotate quickly by suitable driving wheels upon the
cam shaft in the direction in which it is to be turned; another cone surface is
also placed upon the cam shaft to slide upon the fixed key and rotate with the
shaft; these two cone surfaces when one is forced into or against the other form
a "cone clutch." The cone part which slides upon the cone shaft is constantly
forced towards the cone part, which is always rotating, by a spring upon the
cam shaft having its abutment against a collar or cam upon the shaft. Upon
a flange from the sliding cone part as many cam or inclined projections are
formed as the cam shaft has to make movements to complete one revolution,
and when the cam shaft has completed one movement one of these projections
comes against an antifriction bowl in a suitable bracket from the framing,
which forces the sliding cone part endways and so withdraws it from contact
with the other constantly rotating cone part, the momentum of the cam
shaft carrying the highest part of the projection or incline past the centre
of the bowl, so that when the cam shaft is arrested the reverse, incline of
a projection will rest against the antifriction bowl, so that the force of the
spring before mentioned will cause the cam shaft to turn slightly when it is
again released, so that the sliding cone will move towards the constantly
rotating cone, which will carry the cam shaft with it until again arrested, as
above explained. Instead of the arrangement of mechanism above described
the sliding cone part and the "escape plate" may be connected to form one
piece, and the "stops upon the "escape plate lever act in place of the
anti-friction bowl to force the coues out of contact, the withdrawing of the
"stop" permitting the spring to slide the cone into gear directly without first
having slightly to turn the cam shaft before this is effected.
A cam
surface is used with the arrangements described acted upon by a bowl, which is
pressed upon by a spring, or catch or pawl is employed to prevent the rebound
when the cam shaft is arrested.
وو
"
Secondly, my improvements relate to an improved arrangement and com-
bination of mechanism for instantly stopping the machine when a thread
breaks by passing the driving belt to the loose pulleys (this being done by a
spring when a latch is released), and applying the break used for stopping
the winding when the spools or bobbins are filled; and my Invention consists

page_text: in an improved arrangement and combination of mechanism, namely, in a
shaft carried in suitable bearings passing from end to end of the machine, and
which is rotated by a "belt ;" this shaft is made in two lengths, one part being
about the length of the headstock, and it is coupled with the other part of
the shaft by a V toothed clutch box, the headstock end of the shaft being so
arranged that it can move endways, the two halves of the clutches being forced
into gear by a spring acting upon the shaft; there is a clutch fork collar
upon the shaft that slides, which collar is connected with levers so that end
movement in the shaft will act through the levers to put on the brake and
release the latch that is connected with the belt guide rod. End movement is
given to the sliding part of the shaft when the other part of the shaft which
does not move endways is prevented from rotating, as the V or inclined teeth
of one half of the clutch will then act upon the other half of the clutch and
produce this movement. The rotation of the shaft is arrested by a click or
pawl, which is allowed to fall into the teeth of a ratchet wheel when the
thread breaks, there being one pawl and ratchet opposite each thread being
wound. The pawl is held up by the tension of the unbroken thread passing
over rods and through an eye or hook in a wire connected with the pawl.
The surfaces for giving tension to the thread are removed from the thread
guide carrier to a position between. the bobbin from which the thread is
drawn and the eye or hook for sustaining the pawl while the thread is
unbroken.
Thirdly, my improvements consist using a middle stand frame and in
placing the cams in the middle, which transmit their movement by the partial
rotation of the shafts, thus diminishing the effects of torsion in the shafts.
Fourthly, my improvements consist in the use of a knife for each head,
carried upon a rod sliding in suitable bearings in front of the machine, and
having movements from a cam upon the "shaper cam shaft," which will slide
the rod forward when the second layer of thread has been wound upon the
bobbin or spool and cause each knife to cut the loose end of the thread against
the end of the spool or bobbin. This has been bitherto done by hand after
the spools have been filled and discharged by the machine.
Fifthly, the use of a coupling upon the traverse rod so that the thread
guides may be simultaneously adjusted in relation to the shaper, and the use of
shapers where all variations of the breadth are upon one side of a centre line,
the breadth of the shaper upon the other side of the centre line being constant
for all sizes of " shapers."

WINDING YARN OR THREAD ON TO BOBBINS, SPOOLS, OR SIMILAR SURFACES, PARTS
OF WHICH IMPROVEMENTS ARE APPLICABLE TO SELF-ACTING MULES AND LIKE MACHINES
FOR SPINNING, DOUBLING, OR TWISTING FIBROUS MATERIALS," upon the condition
(amongst others) that I, the said William Weild, by an instrument writing

of the said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
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 per-
formed, to be particularly described and ascertained in and by the following
statement (and accompanying Drawings), that is to say :-
The improvements to be herein-after described are made upon and applied
to that machinery for which Letters Patent were granted to me numbered 699,
and dated the Sixteenth day of March, in the year of our Lord One thousand
eight hundred and sixty, and are illustrated by the Figures upon the accom-
panying two Sheets of Drawings.
Fig. 1 is a front elevation, Fig. 2 an end elevation, partly in section, and
Fig. 3 is a plan view of the framing and so much of the parts of a machine
according to my Invention as will be necessary for illustrating the manner of

page_text: carrying out my improvements. The other Figures of the Drawings will be
referred to and explained herein-after.
Before entering into the description of my improvements I will name some
of the parts of my improved machine. A, the framing; a, the first motion
shaft; a', the fast and loose driving pulleys; a², the strap guide upon the upper
end of the vertical shaft (a³), which has an armı (a) at its lower end which
is jointed to a stop rod (a) passing in front of the machine. Upon the
end of the first motion shaft (a) a pulley (a*) is fixed that drives a belt
working upon the pulleys (6) upon the shaft (6), which transmits motion to
the spindles that wind the thread on to the spools. Upon the shaft (¹) the
pulley () is secured, upon which the brake belt (3) acts to suddenly stop the
winding of the thread, this belt being actuated through the lever (b) having
its fulcrum at (6); c is a shaft driven by a wheel upon the boss of one of the
pulleys (6) which gives motion to the cam shaft (c¹) for performing the
operations required in effecting the changes of the spools. d is the belt
changing cam shaft; d, the belt cam; d, the brake lever cam; e is a wheel
upon the belt changing cam shaft (d), which is driven by a wheel upon the boss
of one of the pulleys (b) through an intermediate wheel; f is the shaper;
g', the tail part working upon and against the shaper, and is carried by the
traverse rod (g); f¹ is the shaper cam shaft. The parts above referred to are
more fully explained in the Specification of my aforesaid Patent, No. 699, in
the year of our Lord One thousand eight hundre:l and sixty.
Firstly, my improvements relate to mechanism for actuating the cam.
shaft (d) for effecting the changes in the working of the machine, and these
improvements are applicable to self-acting mules and like machines where a
cam shaft is used.
One modification of my improvements for this purpose is illustrated by
Fig. 8 a side sectional view, and Fig. 9 an end sectional view. The mechanism
consists of an internal cone surface formed upon the side of a wheel (e) which
is made to rotate quickly (by suitable driving wheels) upon the belt changing
cam shaft (d) in the direction in which it is to be turned. The wheel (e) has
its bearings in a bracket secured to the framing (A) as shown. Another come
surface (e) (external) is also placed upon the cam shaft to slide upon a fixed
key (e) and rotate with the cam shaft (d). These two cone surfaces (c and e¹).
when one (e) is forced into or against the other (e) from a "cone clutch."
The cone part (e¹) which slides upon the cam shaft (d) is constantly forced
towards the cone part (e), which is always rotating, by a spring (e) upon the
cam shaft (d), having its abutment against the escape plate (h) or a cam or
col'ar upon the cam shaft (d). Upon a flange (e) from the sliding cone part

page_text: (e) as many cam or double incline projections (e*) are formed as the cam
shaft has to make movements to complete one revolution. Two inclines or
projections are only required in my thread winding machine (see Figs. 8 and 9),
and when the cam shaft has completed one movement one of the inclines or
projections (ex) comes against an antifriction bowl (e) in a suitable bracket
(e) from the framing, which forces the sliding cone part (e) endways, and so
withdraws it from contact with the other constantly rotating cone part (e).
The momentum of the cam shaft will carry the highest part of the projection
or incline (e) past the centre of the bowl (e), so that when the cam shaft
is arrested the reverse incline of the projection (ex) will rest against the anti-
friction bowl (e), and consequently the force of the spring (e) before
mentioned will cause the cam shaft (d) to turn slightly, when it is again
released, and will cause the sliding cone (e¹) to move towards the constantly
rotating cone (e), which will carry the cam shaft with it until again arrested as
above explained.
Another arrangement of mechauism which I prefer to use in place of that
above described is shewn in Figs. 2 and 3, and by the enlarged detached
Figures 5, 6, and 7. Fig. 5 is a side sectional view, and Fig. 6 an end view
of the mechanism, and Fig. 7 is a detached face view of the escape plate
belonging thereto. The sliding cone part (e¹) in this arrangement has two
pins (e) secured in it, which side is a disc part (7) secured to the cam
shaft (d) within the internal cone part (e) which rotates freely upon the
shaft (d), The sliding cone part (e¹) may be connected with or made to
form part of the escape plate (h), as shown. The stop (¹) upon the escape
plate lever (2) acts in place of the antifriction bowl (e) (see Figs. 8 and 9)
to force the cones (e and e¹) out of contact; the withdrawing of the stop
(carried by the escape plate lever (²)) permits the spring (3) to slide the
cone (e) into gear directly without first having slightly to turn the cam
shaft (d) before this is effected. The faces of the stops (3) in escape
plate (h) (see Fig. 7) are inclined upon one edge so as to withdraw the
cone part (¹) at the end of the movement of the cam shaft by coming when
rotated against the escape plate lever (2). In place of the cone surfaced clutch
fine toothed clutches may be used, the inclines for withdrawing the clutch out
of gear being arranged to give sufficient movement to get the teeth clear of
each other before the cam shaft is arrested by the stops upon the escape plate
lever. A cam surface (i) (see Figs. 5 and 6) is used with the arrangements
above described, acted upon by a bow! in the end of a lever (¹), having its
fulcrum (2) upon a bracket from the framing, and this lever (¹) is attached
to one end of a spring (), the other end being secured to the framing (sec

page_text: Fig. 2). is a screw for adjusting the range of the lever ¹. This arrange-
ment or a catel or pawl is employed to prevent rebound when the cam shaft
(d) is arrested.
Secondly, my improvements relate to an improved arrangement and com-
bination of mechanism for instantly stopping the machine when a thread breaks
by passing the driving belt to the loose pulley (this being done by a spring
when a latch is released) and applying the brake used for stopping the winding
when the spools or bobbins are filled; and my Invention consists in an improved
arrangement and combinatlan of mechanism (illustrated in Figs. 1, 2, and 3),
namely, in a shaft ; and j¹ carried in suitable bearings (as shown) passing
from end to end of the machine, and which is rotated by a belt (*) from the
shaft (6), as shown. This shaft (; and j¹) is made in two lengths, one
part (1) being about the length of the headstock, and it is coupled with the
other part () of the shaft by a V toothed clutch box (3), the headstock
end () of the shaft being so arranged that it can move endways, the two
halves of the clutch (j³) being forced into gear by a spring acting upon the
shaft ().
There is a clutch fork collar upon the shaft (¹) which slides
endways, which collar is connected with an arm (j) upon a shaft (j), and
this arm is connected with another arm (5") upon a shaft (7) which has an
arm (8) that comes under the stop rod (a³) and acts to unlatch its end from
the bracket (a) and allow the spring to force the belt from the fast to the
loose driving pulley. The shaft j³ has another arm (") upon it, which is
connected by a rod (*) with the brake lever (b) as shown, and thus acts to
put on the brake. End movement is given to the sliding part of the shaft (1)
when the other part of the shaft (j), which does not move endways, is prevented
from rotating, as the V incline teeth of one half of the clutch (3) will then
act upon the other half of the clutch and produce this movement. The rotation
of the shaft () is arrested by a click or pawl (k), which is allowed to fall
into the teeth of a ratchet wheel (¹) when the thread breaks, there being one
pawl and ratchet for each thread being wound. The pawl (k) is held up by
the tension of the unbroken thread passing over rods and through an eye or
hook in a wire (*) connected with the pawl (k). The surfaces (1) for giving
tension to the thread are removed from the thread guide carrier (92), and are
placed upon a rod () in a position between the bobbin from which the thread
is drawn and the eye or hook () in the wire for sustaining the pawl (k)
while the thread is unbroken. The direction in which the thread passes from
the bobbin to the thread guide is shown in Fig. 2 by peculiar dotted line; it
passes from the bobbin (m) up and over a rod (m²), then down and under a
1od (m), then between the pinching surfaces (1), then through the eye in the

page_text: wire () sustaining the pawl (k), then over the rod (1), upon which the bracket
is secured for carrying the pinching apparatus (2), and then to the thread
guide (g) upon the traverse rod (9). There is a hand wheel (k) which is
geared with the shaft j, so that this shaft may be turned to get the pawls (k)
clear when starting the machine.
Thirdly, my improvements consist in making a middle stand frame (A¹) and
in placing the cams (n) (which transmit their movement by the partial rotation
of shafts) on a shaft (c) extended to the middle of the frame, as shown, thus
diminishing the effects of tension in the shafts acted upon.
Fourthly, my improvements consist in the use of a knife (p) for each head
carried upon a sliding rod (p2) in suitable bearings in front of the machine,
being actuated by a cam (p³) upon the shaper cam shaft (f) which will slide
the rod (p3) forward when the second layer of thread has been wound upon
the bobbin or spool (a), and cause each knife to cut the loose end of the thread
against the end of the spool or bobbin. This operation has been hitherto
performed by hand after the spools have been filled and discharged by the
machine.
The arrangements above explained are illustrated upon Figures 1, 2, and 3,
and by enlarged detached Figures 10 and 11, Fig. 10 being an end elevation,
and Fig. 11 a plan view, partly in section. The knife (p) (see Fig. 11)
is adjustable in an arm (p¹), which is also adjustable upon the sliding rod (p²); |
the end of this rod (p³) is connected by a rod (p') with a lover (p) having
its fulcrum upon a stad (p) in the framing. The end of the lever (p³)
carries a bowl which rests against a cam (p³) upon the shaper cam shaft (¹).
Fifthly, my improvements consist in the use of a coupling (9) upon the
traverse rod (9) so that the thread guides (92) may be simultaneously adjusted
in relation to the shaper (f), and also in the use of shapers where all
variations of the breadth are upon one side of the centre line, the breadth of
the shaper upon the other side of the centre line being constant for all sizes of
shapers, see Fig. 4, representing a shaper (f) in full line uniform upon each
side of the centre line (*), and larger sized shapers with the additional breadth
all upon one side in dotted line.
I have now particularly described the nature of my said improvements, and
claim as my Invention,―
Firstly, the mechanism for actuating the belt changing cam shaft (d) in
combination with my patented machinery for winding yarn or thread on to
bobbins or spools as described, and also the mechanism illustrated by Figs. 8
and 9 when used in self-acting mules and like machines.
Secondly, the improved arrangement and combination of mechanism for

page_text: stopping the machine when a thread breaks, as herein-before described and
illustrated by the accompanying Drawings.
Thirdly, the arrangement of the machine with a middle stand (A¹) with the
cams (), as herein-before described and illustrated by the Drawings.
Fourthly, the system or mode and arrangement of mechanism for cutting
the threads, substantially as herein-before described under the fourth bead of
this Specification.
And fiftbly and lastly, the use of the coupling (93) upon the traverse
rod (9) and of shapers, as herein-before described under the fifth head of this
Specification.
In witness whereof, I, the said William Weild, have hereunto set my hand
and seal, this Eleventh day of October, in the year of our Lord One
thousand eight hundred and sixty-seven.
