Improvements in or applicable to Selfacting Mules for Spinning
Fibrous Materials.
We, WILLIAM THOMAS WATTS and WILLIAM STORRS of the Firm of Taylor, Lang,
& Co. Limited, of Castle Iron Works, Stalybridge, in the County of Chester,
Machine Makers, do hereby declare the nature of the said invention to be as
follows:
Our Improvements are combined with self acting spinning mules, and apply more
especially to mules which operate upon what is termed the woollen system.
Firstly. Our invention relates to arrangements and combinations of mechanism
by which, one, two or three different speeds may be imparted to the spindles.
Two of these speeds are produced in a manner similar to an old and well known
method by using one grooved pulley or "rim" fast upon the end of the "rim
shaft," and a second pulley or "rim" of a different diameter fast upon the sleeve of
a strap or belt pulley which works loose on the "rim shaft," this said strap or
belt pulley being of the same diameter as another pulley which is keyed fast upon
the "rim shaft" so that by moving the driving belt from one pulley to the other
one or the other of the said grooved pulleys or "rims" becomes alternately the
driver of the spindles.
These two speeds of the spindles may be termed the second and third speeds or
middle and greatest speeds.
My invention consists in the application and combination of mechanism to produce
another different speed of the spindles which will be termed the first speed or
slowest speed.
To carry out the invention an additional down driving belt is used driven from
the counter driving shafts.
This additional down driving belt works upon two belt pulleys both loose upon the
"rim shaft" but one pulley has a ratchet pawl or "click" jointed upon a
stud in it which pawl can engage with a ratchet wheel secured upon the rim shaft
when the belt pulley which carries the pawl is rotated, and it thus drives the
rim shaft, but when the rim shaft is driven at a greater speed (the second speed) the
ratchet wheel over-runs the pawl which is then lifted in a well known manner from
its teeth.
The pawl or "click" is the driver until the belt for the other pulleys is traversed
to the pulley fast on the rim shaft for the second speed (or middle speed).
The mechanism on the "rim shaft" will be first described.
Fast on one end of the rim shaft there is a small grooved pulley for driving the
spindles, near this pulley there is a larger grooved pulley for driving the spindles at
the greatest speed which large pulley is fast to one end of a long sleeve free to
rotate on the rim shaft.
At the other end of this long sleeve a belt pulley and friction clutch is secured,
this clutch forming one half of the clutch the other half being formed in a
spur wheel free to rotate on the long sleeve.

page_text: On the long sleeve the worm called the twist. worm is secured.
On the rim shaft adjoining the combined pulley and clutch, and of the same
diameter, are two other belt pulleys, the belt pulley furthest from the combined
pulley and clutch is fast on the rim shaft and upon its boss the other belt pulley
rotates freely.
There are two other belt pulleys on the rim shaft, but between these two pulleys
and the belt pulley fast on the rim shaft a ratchet wheel is secured on the rim shaft,
and in the belt pulley (one of the two above referred to) adjoining this ratchet wheel
there is a stud for a pawl or "click" which can come into the teeth of the
ratchet wheel and drive it, and thus the rim shaft, thus giving the first or lowest
speed.
The belt pulley carrying the pawl has a long boss or sleeve which rotates freely
on the rim shaft, and upon its end is secured the spur pinion that drives the front
rollers.
The long boss of the pawl pulley has a loose belt pulley which rotates freely 1
upon it.
The two endless belts that drive the pulleys on the rim shaft work on pulleys on
the driving counter shaft but the pulley on the counter shaft for the pawl belt pulley
is smaller than that which works on the belt pulley fast on the rim shaft.
When the belt is driving the pawl pulley the pawl drives the ratchet wheel and
thus the rim shaft and the small grooved pulley drives the spindles.
When the other belt drives the pulley fast on the rim shaft it goes quicker and
the ratchet wheel then over-runs the pawl which thus ceases to drive, and when the
last named belt is traversed from the pulley fast on the rim shaft passing over the
loose pulley adjoining it on to the combined pulley and clutch on the long sleeve, :
the large grooved pulley then drives the spindles, the rim shaft being free to
rotate slower.
The driving belt working on the pulley fast on the rim shaft and those pulleys
adjoining it is traversed to and fro by a belt guide arranged as follows.
The belt guide is a lever or arm, the lower end of which is loose on a horizontal
belt guide shaft in bearings in the framing-the upper end of this arm has the eye
or belt guide fork secured to it.
On the belt guide shaft a lever is secured which extends above the shaft and has a
horizontal arm projecting from it to which one end of a helical spring is adjustably
secured, the other end of the spring is secured to an arm projecting horizontally 3
from the belt lever loose on the belt lever shaft.
The arm of the lever loose on the belt lever shaft extends below it, and it is
jointed to a part connected with one end of a rod which extends to the vertical arm of
a bell crank lever and this rod can be adjustably connected by a screw nut with this
The fulcrum of this bell crank lever is on a bracket which can be adjusted
on the headstock framing to and from the rollers.
arm.
The horizontal arın of this bell crank lever can be depressed so as to move the helt
guide lever and traverse the belt from the loose pulley to the pulley fast on the
rim shaft. On a bracket on the carriage an oscillating finger is jointed, which comes
against a stop on the bracket and is rigid in one direction, but will give way in the 4
other direction.
When the carriage is moving out, this finger is rigid and acts upon the horizontal
arm of the belt crank lever and depresses it so as to operate the belt guide lever as
above explained, but when the carriage is going in (towards the roller) this finger
gives way and does not operate on the bell crank lever. There are two bell crank
levers on a stud in the framing. The vertical arms of this bell crank lever are acted
upon by cams or fingers on the twist shaft so that their horizontal arms are lifted at
the times required.
The horizontal arm of one of these bell crank levers acts to latch and hold the loose
belt fork arm on the fast pulley, and the other acts to latch and hold the arm secured
on the belt guide shaft when the belt is on the combined pulley and clutch. The

page_text: belt guide for the other belt which works on the pawl pulley is a vertical lever,
the lower end of which is jointed on a stud in the framing, the upper end of
this vertical lever has the belt eye or fork secured to it.
One end of a helical spring is secured to this lever and the other to a stud in
the framing.
This helical spring when in tension acts to traverse the belt from the loose to the
fast or pawl pulley, but it is prevented from doing so, except when required by a bell
crank latch lever on a fulcrum stud in a bracket in the framing-The horizontal
arm of the bell crank lever forms a hook latch to catch upon a projection from
the belt guide lever and this hook latch is lifted and released when the carriage
has gone in when the nearest faller shaft strikes against the vertical arın of the
bell crank latch lever, and lifts its horizontal arm and allows the helical spring to
traverse the belt on to the pawl pulley which then drives the spindles at the slow
speed through the ratchet fast on the rim shaft.
To the belt guide lever one end of a rod jointed, the other end of which rod is
jointed to the vertical arm of a bell crank having its fulcrum on a stud in a bracket
secured to the framing.
The end of the horizontal arm of this bell crank lever is inclined and when the
carriage is nearly out at its full stretch, the outer faller shaft comes against this
incline and pulls the belt guide and thus traverses the belt from the pawl pulley
to its loose pulley and thus stops the rollers. To arrest the momentum of the
pawl pulley there is a brake lever having its fulcrum on a bracket on the framing.
The upper end of this lever has a brake block secured to it to act upon the pawl
pulley when allowed by the force of a spring connected with the brake lever.
There is a rod, one end of which can slide in a hole or slot in the bracket for the
fulcrum of the brake lever, the other end of this rod can slide freely in another
bracket on the framing, this rod being in its lengthway in the direction in which the
carriage moves.
This rod has two arms from it adjustable in its lengthway against which the faller
shafts can come so as to move the rod endways at or near each end of the stretch or
movement of the carriage but in opposite directions.
When the rod is moved one way by the carriage at the end of the stretch, that
end of the rod which passes through the slot in the bracket carrying the fulcrum of
the brake lever being inclined withdraws from the tail of the brake lever and allows
the spring to press the brake upon the periphery of the pawl pulley-When the rod
is acted upon in the opposite direction as when the carriage moves to the rollers, the
incline on the rod lifts the brake from the pawl pulley against the action of the
spring.
The cam on the changing shaft moves the belt guide for the pulley fast on the
rim shaft in one direction-the movement in the other direction being from the
hinged finger on the carriage as above explained.
When the carriage has arrived nearly at the rollers, the belt guide then holding
the belt on the loose pulley is released the latch being lifted, as above explained, and
the helical spring traverses the belt from the loose pulley to the pawl pulley, and
thus drives the spindles at the slow speed. When the carriage has moved out to
the required extent, the hinged finger on the carriage moves the loose belt guide
lever which was holding the belt on the loose or middle pulley on to the pulley fast
on the rim shaft, which is then driven faster than the pawl pulley can drive it.
Next the change cam acts upon the belt lever shaft and oscillates it and the lever
fast upon it which extends the helical spring but at this time one of the bell crank
latch levers is holding the loose belt lever to retain the belt on the pulley fast on
the rin shaft.
The twist shaft by the finger upon it releases the latch and the loose belt lever
is, then traversed by the helical spring from the pulley fast on the rim shaft across
the loose pulley on to the combined pulley and clutch on the long sleeve which
then drives the large grooved pulley and thus the spindles at the greatest speed,

page_text: the other bell crank latch lever holding the lever fast on the belt guide shaft
until released by the other finger of the twist shaft when the belt is traversed to the
loose pulley.
The brake on the pawl pulley is operated when the belt is traversed from the pawl
pulley to the loose pulley as above explained.
"
Secondly. Our invention relates to a method of driving the "drawing out
mechanism of the carriage in such manner that the rollers may at will be allowed
to start into rotary motion a little in advance of the carriage and to such extent as
may be deemed desirable.
The rollers and " drawing out or "back shaft" shaft are driven primarily by the
same range of wheels both having sliding clutches actuated simultaneously from
the cam shaft.
The sliding clutch box upon the "back shaft" has two snugs which take into
two spaces in a disc keyed fast upon the shaft and when the two parts of the
clutch box are out of gear these said snugs are held against or towards the non-
driving sides of the spaces in the disc by a spring acting to rotate the sliding
clutch but when the clutch box slides into gear, the snugs move forward through the
spaces in the disc towards the driving sides of the spaces therein and thus drive the
"drawing out motion."
Whilst the snugs are moving from the non-driving side of the spaces to
the driving, sides, the carriage is of course stationary but the rollers are delivering
the sliver to be twisted.
The length of the spaces in the dise through which the snugs have to pass before
they begin to drive, being adjustable, the attendant may cause more or less
sliver to be delivered from the rollers at will before the carriage begins to move from
the rollers.
The mechanism will be further described as follows:-
On the "back shaft" the "back shaft wheel" and one part of the clutch box
combined, and the other part of the clutch which slides upon the back shaft are
placed.
Both parts of the clutches are free to rotate to a given extent on the back shaft as
hereinafter explained.
On the "back shaft" in the hollow between the two parts of the clutches a disc is
keyed with two notches in it (by preference) on opposite sides of the disc into which
two snugs or projections can enter formed upon the sliding part of the clutch, but
these snugs do not fill the notches in the discs but there is "play" for the snugs in
the direction of rotation. A spring is arranged, one end of which is attached to the
disc, and the other or free end acts upon the sliding clutch part to rotate it (when the
clutches are out of gear) back from that side of the notches in the disc against which
the suugs come when driving the clutches.
But this backward rotation can be limited by a projection on the boss of the sliding
part of the clutch which comes in contact with a projection from a collar adjustable
round the "back shaft" and by this means the amount of play of the snugs in the
notches can be regulated, and consequently the space through which the clutches
will have to rotate upon the back shaft after being brought into gear can be
regulated.
If the space is little or none, the "back shaft" begins to be rotated immediately,
but if the space is much, the wheel and clutch rotates longer before the "back
shaft" begins to be rotated, and as the "drawing rollers" begin to rotate when the
clutch begins to rotate, the rollers begin to rotate in advance of the beginning of the
going out of the carriage which is driven by the back shaft.

Fibrous Materials.
We, WILLIAM THOMAS WATTS and WILLIAM STORRS, of the Firm of Taylor,
Lang & Co. Limited, of Castle Iron Works, Stalybridge, in the County of Chester,
Machine Makers, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement:---
Our improvements are combined with selfacting spinning mules, and apply more
especially to mules which operate upon what is termed the woollen system.
Our invention will be illustrated by reference to the accompanying drawings of
which-

Fig. 8, is a sectional elevation of the clutch mechanism, the section being in the
plane of the lengthway of the "back" shaft or carriage drawing out shaft for giving
inotion to the carriage.
Figs. 1 to 6 and 4, 5 and 6 inclusive, illustrate the first and Figs. 7 and 8, the
second parts of our invention.
Firstly. Our invention relates to arrangements and combinations of mechanism by
which one, two or three different speeds may be imparted to the spindles.
Two of these speeds are produced in a manner similar to an old and well known
method by using one grooved pulley or "rim" fast upon the end of the "rim shaft,"
and a second grooved pulley or "rim" of a different diameter fast upon the end of
the sleeve of a strap or belt pulley, which sleeve works loose on the "rim shaft," this
said strap or belt pulley being of the same diameter as another pulley which is keyed
fast upon the "rim shaft" so that by moving the driving belt from one pulley to the
other one, one or the other of the said grooved pulleys or "rims "becomes alternately
the driver of the spindles.
These two speeds of the spindles may be termed the second and third speeds or
middle and greatest speeds.

page_text: Our invention consists in the application and combination of mechanism to produce
another different speed of the spindles which will be termed the first speed or slowest
speed.
To carry out the invention an additional down driving belt is used driven from the
counter-driving shaft which drives the belt for the second and greatest speeds.
This additional down driving belt works upon two belt pulleys c and c¹, both loose
upon the "rim shaft a, but one pulley c, has a ratchet pawl or "click" c², (see
Figs. 3 and 4), jointed upon a stud or pin c³, secured by a screw to the side of the
pulley c, which pawl c2, can engage with a ratchet wheel c, secured upon the rim
shaft a, when the belt pulley c, which carries the pawl is rotated, and it thus drives
the rim shaft", but when the "rim shaft" is driven at a greater speed (the
second speed) the ratchet wheel c³, over-runs the pawl c², which is then lifted in a
well known manner from its teeth, namely:-
:―
There is a projection from the boss part of the pawl c², in which there is a pin c",
secured to project on one side.
In the boss of the ratchet wheel c, there is a
groove c', which is grasped by a spring clip c³, to give a sufficient amount of
friction.
'
An arm c, from this clip extends to the pin c, and is bent to form a fork to
embrace the pin c.
When the pulley c, is driven in the direction to rotate the ratchet c, the pin cº, is
held back until it has oscillated the pawl c², to bring its end into and against the teeth
of the ratchet c', when the ratchet and pulley c, will rotate together, but when the
"rim shaft a, is driven faster than the ratchet wheel e, then the spring clip c³, acts
to lift the pawl c², from the teeth of the ratchet wheel c, and the spring clip then
slips round its groove in the boss of the ratchet, the friction being only sufficient to
oscillate the pawl. The stud c³, secures a bracket ct, to the pulley c, and this
bracket c', carries a stud or pin cx, which prevents the pawl from lifting too far away
from the ratchet.
The pawl or "click" c², is the driver until the belt for the other pulleys is traversed
to the pulley (63) fast on the "rim shaft " a, for the second speed (or middle
speed).
The mechanism on the "rim shaft" a, above referred to, will be now more parti-
cularly described.
Fast on one end of the "rim shaft" a, there is a small grooved pulley a¹, for
driving the spindles in the usual manner; near this pulley there is a larger grooved
pulley b¹, for driving the spindles in the usual manner, at the greatest speed, which
large pulley is fast to one end of a long sleeve b, free to rotate on the "rim
shaft a.
At the other end of this long sleeve b, a combined belt pulley 2, and friction
clutch, is secured, this clutch forming one half of the clutch, the other half 68,
being formed in a spur wheel bo, free to rotate on the long sleeve b. The wheel bo,
and clutch 65, is the ordinary arrangement for driving the spindles when backing off,
the wheel bª, being constantly driven drives the spindles through the clutch 65, when
backing off the thread from the spindles.
On the long sleeve b, the worm 67, called the twist worm, is secured, by
which the twist shaft is rotated and to which one revolution is given for each
stretch.
On the "rim shaft" adjoining the combined pulley and clutch 62 and 65, and of
the same diameter, are two other belt pulleys bs and 6, the belt pulley 63, furthest
from the combined pulley and clutch is fast on the "rim shaft" and upon its boss
the other belt pulley b, rotates freely, being a loose pulley.
There are two other belt pulleys c, and c¹, on the "rim shaft" hereinbefore men-
tioned, but between these two pulleys and the belt pulley fast on the "rin shaft" a
ratchet wheel, is secured on the "rim shaft," and in the belt pulley (one of the
two above referred to) adjoining this ratchet wheel there is a stud or pin c³, for a
pawl or "click", which can come into the teeth of the ratchet wheel, and drive
it as above explained, the "rim shaft" thus giving the first or lowest speed.

page_text: The belt pulley c, carrying the pawl has a long boss or sleeve c, which rotates
freely on the "rim shaft" and upon its end is secured the spur pinion cb, that drives
the front rollers.
The long boss ca, of the pawl pulley has the loose belt pulley c¹, which rotates
freely upon it. a², is a bearing for the sleeve c; and a³, the bearing for the
sleeve b.
The two endless belts that drive the pulleys on the "rim shaft" work on pulleys
on the driving counter-shaft, but the pulley on the counter-shaft for the pawl belt
pulley c, is smaller than that which works on the belt pulley 63, fast on the "rim
shaft."
When the belt is driving the pawl pulley c, the pawl c², drives the ratchet wheel
as before explained, and thus the "rim shaft" and the small grooved pulley a¹,
drives the spindles.
When the other belt drives the pulley 63, fast on the "rim shaft" it goes quicker
and the ratchet wheel c², then over-runs the pawl which thus ceases to drive (but the
pulley c, is still driven by its belt) and when the belt is traversed from the pulley b³,
fast on the "rim shaft" passing over the loose pulley b, adjoining it on to the com-
bined pulley 62, and clutch 65, on the long sleeve b, the large grooved pulley b¹, then
drives the spindles, the "rim shaft" being free to rotate as it is driven by the small
pulley a¹.
"
It will be noted that both " rim or groove pulleys and b¹, drive the spindles
and that the pulley a¹, does the driving for the first and second speeds, but when the
quick speed pulley 61, becomes the driver, it drives the shaft in the ordinary manner
previously driven by the pulley a¹, quicker than a will drive it, consequently that
pulley (b) becomes a driving pulley to the pulley a¹, driving the rim shaft, (which
is then free) at a quicker speed in the same direction. In like manner the
rim b, is driven when the rim a¹, is the driver, as in the ordinary arrangement.
The driving belt working on the pulley 63, fast on the "rim shaft" and those
pulleys adjoining it is traversed to and fro by a belt guide arranged as follows.
The belt guide d is a lever or arm, the lower end of which is loose on a horizontal
belt guide shaft d', in bearings in the framing, the upper end of this arm d, has the
eye or belt guide fork d², secured to it.
On the belt guide shaft d', a lever d³, is secured which extends above the shaft d',
and has a horizontal arm d, projecting from it to the downwardly bent end of which
one end of a helical spring d, is adjustably secured so that its tension may be
regulated, the other end of the spring is secured to the turned up end of an arm d",
projecting horizontally from the belt lever d, loose on the belt lever shaft d'.
The arin of the lever d, loose on the belt lever shaft, extends below it, and it is
jointed to a part d', connected with one end of a rod d³, which extends to the vertical
arm do, of a bell crank lever, and this rod 8, can be adjustably connected by a
screw nut d, with this arm. The fulcrum db, of this bell crank lever is on a
bracket do, which can be adjusted on the headstock framing x, to and from the
rollers.
The horizontal arm d, of this bell crank lever can be depressed so as to move the
belt guide lever d, and traverse the belt from the loose pulley 64, to the pulley 6³,
fast on the rim shaft" a, after the first part of the stretch.
On a bracket y', on the carriage y, an oscillating finger 32, is jointed at y³,
which comes against a stop y, on the bracket y¹, and is rigid in one direction, but
will give way in the other direction.
When the carriage y, is moving out, this finger 2, is rigid and passes on one
side of the fulcrum db, and its end acts upon an inclined plate de, on one side of the
horizontal arm da, of the bell crank lever and depresses it so as to operate the belt
guide lever d, as above explained, but when the carriage y, is going in (towards the
rollers) this finger y², gives way and does not operate on the bell crank lever.
There are two bell crank levers e and e¹, on a stud e², in a bracket (not shown) in
the framing.
The vertical arms of these bell crank levers are acted upon by cams or fingers €³

page_text: and e, on the "twist" shaft 5, so that their horizontal arms are lifted at the time
required by the said fingers.
.
A notch (one of two) one on the end (the other near the end) of the horizontal
arm of one of these bell crank levers'e, acts to latch upon a stud or projection de, and
hold the loose belt fork arm d, on the fast pulley 63, and the other notch to hold it
upon the loose pulley b', as shown in Fig. 2, and the other lever (e) acts to latch
by a downward hook e, and hold on a notch d', in the arm d', from the arm d³,
secured on the belt guide shaft d¹.
The belt guide co, for the other belt for the slow speed which works on the pawl
pulley c, is a vertical lever, the lower end of which is jointed on a stud cd, in the
framing, the upper end of this vertical lever has the belt eye or fork ce, secured
to it.
One end of a helical spring c', is secured to this lever c, and the other adjustably
to a stud or projection c, in the framing.
This helical spring c', when in tension, acts to traverse the belt from the
loose pulley c¹, to the fast or pawl pulley c, but it is prevented from doing so, except
when required by a bell crank latch lever f, f¹, on a fulcrum stud f³, in a bracket f³,
on the framing. The end of the horizontal arm f, of the bell crank lever forms a hook
latch to catch upon a projection c", from the belt guide lever ce, and this hook latch is
lifted and released when the carriage y, has gone in when the nearest faller shaft y*,
strikes against the lower end of the vertical arm f¹, of the bell crank latch lever, and lifts
its horizontal arm and allows the helical spring c', to traverse the belt on to the
pawl pulley c, which then drives the spindles at the slow speed through
the ratchet c, fast on the "rim shaft "a. The faller shaft y, may strike against the
lever f, or against a part f4, adjustable upon the lever f¹, or instead of the faller
shaft, a projection 5, from one of the brackets carrying the bearings of the faller
shafts, see Figs. 1 and 2. To the belt guide lever ce, one end of a rod g, is jointed
at c', by a filbow or fork, the other end of which rod is jointed in a similar way to
the vertical arm g', of a bell crank g', g³, having its fulcrum g², on a stud in a
bracket g', secured to the framing.
The end of the horizontal arm of this bell crank lever is inclined upwards and
when the carriage is nearly out at its full stretch, the outer faller shaft y5, comes
against this incline and moves the lever and pulls the belt guide c, and thus
traverses the belt from the pawl pulley to its loose pulley c¹, where it is held by
the latch f.
The end of the arm f, has two hook steps, one as shown in Fig. 2, holds the belt
guide lever cc, with the belt on the loose pulley c', the other step holds (against the
pull of the spring c) when the belt guide lever has guided the belt on to the
pulley c.
Should it slip by accident the lever c, will come against a stud c, in the framing.
To arrest the momentum of the pawl pulley c, when the belt has been traversed
on to the loose pulley, there is a brake lever h, having its fulcrum h³, on a bracket h³,
on the framing.
The upper end of this lever has a brake block h¹, secured to it to act upon the
periphery of the pawl pulley c, when allowed by the force of a spring hª, connected
with the brake lever to act to press the brake block h¹, upon the pulley c.
There is a rod h', one end of which is adjustably connected with a bar h', inclined
on its vertical edge, the bar can slide in a hole or slot in the bracket h³, for the
fulcrum h², of the brake lever h, the other end of this rod h4, can slide freely in a
projection from another bracket ho, on the framing, this rod h, being in its
lengthway in the direction it which the carriage g, moves to and from the
rollers.
This rod ht, has two arms h and 8, from it adjustable in its lengthway against
which the faller shafts y5 and yo, can come so as to move the rod h4, endways at or
near each end of the stretch or movement of the carriage but in opposite directions.
When the rod h¹, is moved one way by the carriage y, at the end of the stretch, that
end of the part h³, which passes through the slot in the bracket h³, carrying the

page_text: fulcrum of the brake lever being inclined, withdraws from the tail of the brake
lever h, and allows the spring h³, to press the brake h', upon the periphery of the
pawl pulley c. When the rod is acted upon in the opposite direction as when the
carriage y, moves to the rollers, the incline on the part h³, lifts the brake h¹, from
the pawl pulley against the action of the spring.
Figs. 4, 5 and 6^, show the mechanism more clearly which actuates the belt
guide lever d.
The letters of reference marked thereon and herein before mentioned will explain
the parts. Fig. 6^, shows some of the parts which are represented in Figs. 1 and 2 and
in the same plane, but Figs. 4 and 5, show the parts at a right angle to the plane
of Fig. 6A and Figs. 1 and 2. The arm d³, having the bent projection d+, is fast and
the lever d, is loose on the shaft d¹, as before stated. On the other end of the
the shaft d¹, shown in Figs. 4 and 5ª, there is a two armed lever de, dh, one arm d,
is bent as shown best in Fig. 44, and comes over a cam b, on the changing shaft 1, the
other arm dh, of this lever has a side projection d', which comes between jaws ³, on
a L lever dk, which is free to oscillate on the shaft , and to a pin d', in the side of
the vertical arm of the L lever dk, one end of a helical spring dm, is attached, the
other end being secured to a projection d", from the headstock framing (see Fig. 1).
This spring dm, will pull the arm d, against the cam 1, when free to do so.
the changing shaft 11, partly rotates the cam l, acts at one movement upon the
arm ds, which oscillates the shaft d', and consequently moves the L lever (, against
the action of the spring dm, and the lever d³, increasing the tension of the spring d³,
and when this action by the changing shaft U, takes place, the L lever e¹, drops, and
its hook end e, catches upon the projection, snug or ledge d', on the arm d*, of the
lever d³, and holds it until released by the twist finger et, which acts upon
the L lever e¹, to lift its hook end.
When
The operation of the mechanism is as follows:-When the carriage y, arrives at
the rollers, the changing cam shaft l', makes a partial rotation and the cain l,
oscillates the shaft d¹, to the right when looking towards Figs. 1, 2 and 64, as above
explained and in doing so increases the tension of the springs dm and d³.
When this movement of the arm d³, takes place the loose belt lever d, is held in
the position shown in Figs. 1 and 2 with the driving belt on the loose pulley b', by
the notch near the end of the L lever e, at the same time when the carriage has
arrived at the rollers, the projection from one of the brackets for the fallers or the
faller y, releases the latch arm f, and allows the spring c', to traverse the belt by
the lever cc, from the loose pulley c¹, to the pulley c, which as before explained drives
the spindles at the slow or first speed. As the carriage moves out from the
roilers the finger y², acts upon the incline do on the L lever dd, which causes the
lever d, to traverse the belt from the loose pulley 6*, to the fast pulley 63, and thus
to give the middle or second speed to the spindles, this movement of the lever d,
causing the spring d', to be further extended, the pull of this spring being then
resisted by the action of the cam l, and the hook end dº of the lever e¹, is in position
to resist the action of the spring d³, when the changing shaft makes its next
movement. When the third speed is required which is after a fixed number of twists
or turns of the spindles the twist finger e³, lifts the lever e, and the extended
spring d, then acts to move the belt from the pulley 63, over the pulley bt, to the
pulley 62, which thus gives the third or greatest speed to the spindles.
The carriage will then have arrived at the end of the stretch when the faller
shaft y, passes under the arm g³, and moves the belt guide co, to traverse the belt
from the pulley c, to the pulley c¹, the catch lever f, holding it in that position.
At this time the changing shaft l, makes half a revolution as usual and the cam l,
moves out of contact and clear of the arms, and when the number of twists fixed
upon have been given the twist finger e, acts to lift the arm of the L lever e¹, to
release its hook end from the snug or projection d' on d, and by the action of the
spring dm, the lever d, takes the position with the belt on the loose pulley 6*, as
shown in Figs. 1 and 2 which lever d, is held by the spring dm, in one direction and
the cam l, in the other direction and so on for each stretch.

page_text: The brake is applied to the slow or first speed pulley c, when the carriage arrives
out at the full stretch from the spindles and it is lifted therefrom when the carriage
moves to the rollers or a little before it arrives closed in to the rollers about which
time the belt is traversed from the pulley c¹, to the pulley c, to drive the spindles at
the slow or first speed.
"
Secondly. Our invention relates to a method of driving the drawing out
mechanism of the carriage y, in such manner that the rollers and spindles may at
will be allowed to start into rotary notion a little in advance of the carriage and to
such extent as may be deemed desirable.
The rollers and drawing out" or "back shaft" shaft, are driven primarily by the
same range of wheels both having sliding clutches actuated simultaneously from the
cam changing shaft in the ordinary manner.
The sliding clutch box k¹, upon the "back shaft" or drawing out shaft k, has two
snugs 2, which take into two spaces ³, in a disc ', keyed fast upon the shaft k, and
when the two parts and 5, of the clutch box are out of gear, these said
snugs, are held against or towards the non-driving sides of the spaces k³, in the
disc k, by a spring, secured at one end by a screw 7, in the disc k, and at the
other end pressing against a stud 8, in the disc part of the sliding clutch k¹, and
acting to rotate the sliding clutch ¹, when free but when the teeth, of the clutch
box ¹, slides into gear the snugs 2, move forward through the spaces ³, in the
disc towards the driving sides of the spaces therein and thus drive the "drawing out
motion for the carriage y.
"
Whilst the snugs k², are moving from the non-driving side of the spaces k³, to the
driving sides, the carriage y, is of course stationary but the rollers have begun to
deliver the sliver to be twisted.
The length of the spaces 3, in the disc, through which the snugs ², have to
pass before they begin to drive, being adjustable, the attendant may cause more or
less sliver to be delivered from the rollers at will before the carriage y, begins to
move from the rollers.
The mechanism will be further described more particularly as follows:-
On the "back shaft" k, the back shaft wheel"³, and one part of the toothed
clutch box combined with it, and the other part of the clutch k¹, which slides upon
the "back shaft" are placed. The clutch part k¹, is free to rotate to a given extent
on the "back shaft" k, as hereinafter explained.
On the back shaft "k, in the hollow between the two parts of the clutches a
disc k, is keyed with two notches, in it (by preference) on opposite sides of the
disc 4, into which two snugs or projections 2, can enter formed upon the sliding part
of the clutch k¹, but these snugs do not fill the notches k², in the discs +, but there
is "play" for the snugs in the direction of rotation.
.
A spring ko, is arranged, one end of which is attached by a screw 7, to the disc k',
and the other or free end acts against a pin ", upon the sliding clutch part k', to
rotate it (when the clutches are free and out of gear) back from that side of the
notches in the disc k, against which the snugs 2, come when driving the clutches.
But this backward rotation can be limited by a projection ka, on the boss of the
sliding part of the clutch ¹, which comes in contact with a projection kb, from a
collar, adjustable round the "back shaft" k, being then secured thereto by a set
screw, and by this means the amount of play of the snugs k², in the notches can
be regulated, and consequently the space ³, through which the clutches will have to
rotate upon the "back shaft" k, after being brought into gear can be regulated. If
the space is little or none, the "back shaft" k, begins to be rotated immediately, but
if the space is much, the wheel and clutch rotates longer before the "back shaft"
begins to be rotated, and as the "drawing rollers" and spindles begin to rotate when
the clutch begins to rotate, the rollers begin to rotate in advance of the beginning of
the going out of the carriage y, which is driven by the "back shaft" k.
The wheel, is loose on the back shaft k, and is driven by the gearing which
drives the rollers.
