Improvements in Ring-spinning and Doubling Machinery.
We, SAMUEL HERBERT BROOKS, of Union Iron Works, West, Gorton, and Junction
Iron Works, Miles Platting, Manchester, both in the County of Lancaster, Machine
Maker, and FRANK BARLOW, of Gorton Mills, Gorton aforesaid, Assistant Manager,
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 invention relates to combinations and arrangements of mechanism for auto-
matically stopping the machine when the set of spools is full, and at the same time
winding back the copping apparatus and ring rail into the position ready for doffing
and commencing a fresh set of spools.
Our invention is carried into effect by combinations with the ordinary mechanism
of the ring spinning and doubling machinery one modification of which will be
described by reference to fig. 1 an end elevation partly in section, and fig. 2 a side
elevation at the end of the frame which is shown partly in section.
a, is the framing of the machine.
b, is the tin drum shaft having the ordinary fast and loose driving pulleys b',
upon it.
bas a
a', is a longitudinal bar or rail of the framing upon which can slide to and fro a
grooved plate c, which carries the belt fork or guide c*.-This grooved plate c,
toothed rack formed upon it that gears with a wheel c', fast upon a vertical shaft c³,
rotating in a boss in the framing, the upper end of the vertical shaft having a handle c³,
by which the shaft c³, can be rotated and the belt guide moved to and fro.
d, is the shaft for the heart wheel or cam d, which is arranged in the ordinary
manner and acts upon a bowl carried on the heart wheel lever d', which has its fulcrum
at d.
This lever d, carries a stud having a wheel d*, loose upon it fast upon the boss of
which there is a ratchet wheel do, which is acted upon by a hooked pawl d³, jointed
upon a stud.
The boss of the ratchet wheel d, has a square formed upon it for a key to wind back
or adjust the copping mechanism by hand.
The spur wheel d, gears with one d', fast upon the end of a shaft d³, having its
bearings in the lever d, which shaft d³, has a worm d, upon it in gear with a worm
wheel e, on a shaft e¹,having its bearings also on the lever do, but at a right angle to
the shaft ds.
The shaft e, has a pulley ³, secured upon it to which one end of a jointed chain e³,
is attached, the other end of the jointed chain being secured to a pulley f1, on the
end of one of the shafts f, for actuating the ring or copping rail, the shaft f, for one
side of the frame being connected to that for the other side.
The mechanism above described by letters of reference are well known parts of
known ring spinning and doubling frames, and have been referred to in order that the
following explanation of our invention and the mode of carrying it into effect may be
understood.
We will first describe the mechanism for winding back the copping mechanism.
g, is a bevel wheel which is driven from any suitable and convenient rotary part of
the machine, and is constantly in rotation when the machine is working.
With this bevel wheel g, another bevel wheel can be made to gear, which wheel g', can
slide to and fro on a fixed key on a horizontal shaft g', having its bearings in a bracket
secured to the framing, the other end of which shaft g³, has another bevel wheel g³,
secured upon it, that gears with one g*, having a long boss which has its bearings in a
part jointed to a bracket at g', so as to be capable of oscillating slightly.

page_text: The upper end of a vertical shaft 98, passes and can slide freely up and down
through the long boss of the bevel 9, to which it is connected so that the two will
rotate together by key and key groove.
The lower end of the shaft 9, has its bearing in a part hinged at 97, to a bracket
upon the lever d, and there is a bevel wheel 98, at the lower end of the shaft 9,
gearing with one g, upon the worm shaft d³, in the lever d².
The lower end of the vertical shaft g, moves up and down with the heart. wheel
lever d², and its upper end slides up and down through the long boss of the bevel
wheel g, and the jointed bearings perinit of a slight change in the vertical position of.
the shaft 9, in its up and down movements.
h, is a bent lever having its fulcrum on a bracket at h¹, the upper end of this lever is
formed as a clutch fork to fit a groove in the boss of the bevel wheel g¹.
The lower end of the bent lever h, is weighted by a suspended or other weight h
or is acted upon by a spring so that the lever is constantly acting to bring the bevel
wheel g¹, into gear with the constantly rotating bevel g.
To the lower end of the bent lever h, one end of a rod or arm /³, is jointed, the
other end of which comes over a pulley upon the shaft e', which pulley has a hook
projection, upon it that is arranged to come against the end of the rod or arm'h³,
just before the winding down of the copping mechanism is about to be completed, so
that this finger h, acts to push the end of the rod or arm h³, and thus acts upon the
bent lever, to cause it to slide the bevel wheel g¹, out of gear with the constantly
rotating wheel g.
In the position in which the bent lever h, is shown in fig. 1, the bevel wheels g¹, and g,
are out of gear, and they are permitted to go into gear by a rod i, which is jointed
to the bent lever h, at one end, the other end sliding in a hole in a bracket a²,
secured to the framing. The rod i, near the bracket a³, has a projection, which
comes against an arm j³, (part of a three armed casting) secured upon a rod or bar j,
sliding in the lengthway of the machine in suitable bearings, but when this arm,
moves, the projection ³, on the rod i, is released and the wheel g¹, is allowed to go into
gear with the wheel 9.
To a stud in an arm 1, one end of a chain 7, is attached and it then
passes over.
a pulley, in a bracket a³, the other end of the chain having a weight j³, attached,
which is constantly acting to move the sliding bar j, endways.
From the slide bar j, there is an upward arm 2, that comes against a stud c², in the
side of the belt guide slide c.
Thus arranged the moving of the belt guide to start the machine will also move the
arm, and with it the sliding bar j, and then the belt guide may be moved either way;
without acting upon the sliding bar, as hereinafter explained.
The lower arm, has a stud for the joint of a hook pawl de, which comes against
the ratchet wheel d³, of the copping mechanism and gives motion to it at each descent
of the heart or cam wheel lever d
When the sliding bar j, is moved by the weight 1, the jointed pawl do, is taken
clear of the ratchet d³, so that the mechanism can be rotated back, tund when the
sliding bar j, is moved to the position which it occupies when the frame is started (as
shown in fig. 2) the pawl do, is brought back to operate upon the ratchet d³.
Upon the copping rail lifting shaft f, a box cam f'; is secured the groove of which
fits a bowl fx, upon a stud at the lower end of a bar or rod f³, arranged in suitable
guides to slide vertically. To the upper end of the sliding bar rod f, a finger is
jointed at f, the tail part fe, of which is weighted to keep the finger f, vertical, this
finger can turn upon its joint f³, in one direction but not in the other direction..
The upper end of the finger comes opposite and in front of a stud 1, in the side of
the sliding bar, and thus prevents the weight, from moving it, but as the copping
rail ascends higher and higher this finger f*, descends and at last gets below and
releases the stud, and when this takes place (as it is arranged to do when the set: of
spools are full of yarn or thread) the weight, acts to move the driving belt from
the fast to the loose pulley, the first part of this movement releases the starting

page_text: rod i, which puts the bevel wheels in gear and this winds down the copping
mechanism until the action is stopped as hereinbefore explained.
When the copping mechanism has been wound down, the finger f4, has been lifted
to its highest position, and the stud, in the sliding bar j, will be on the contrary
side of the finger f, to that in which it is shown in fig. 2 and some distance from it
so that when the sliding bar j, is moved as when the driving belt is placed upon the
fast driving pulley, the stud, turns the finger f*, on its fulcrum, to one side, until
it has passed, when the weighted tail part, causes it to take the erect position again
and thus hold the stud 1, and prevent the sliding bar j, from moving until the set of
spools are again filled with yarn or thread.
Fig. 3 is an end elevation partly in section and fig. 4 is a side elevation of the end
of a frame partly in section illustrating a modification which is the same as that
illustrated by figs. 1 and 2, except as hereinafter explained.
The worm shaft do, in the heart wheel lever d, is geared by bevel wheels and a
vertical shaft g, with a bevel wheel upon a horizontal shaft. g, having bearings
carried in brackets secured to the framing and a worm k, on the horizontal shaft g³,
gears with a worm wheel k¹, on a stud 2, in the bracket carrying the shaft g.
There is a bevel wheel g¹, sliding on a fixed key on the horizontal shaft g², which
has a groove in its boss with which one end of a bar 2, is connected, the other end of
this bar being guided in a hole in a bracket a², secured to the framing.
This bar, has a projection it, that hooks upon the arm j¹, in one position, and
when the bar, slides back the hook ¹, is released and the helical spring 3, on the
shaft g, between the worm k, and bevel wheel g', forces the latter into gear with the
bevel g; which is constantly rotating when the machine is in-motion.
This causes the worm shafts d³, and g³, to be rotated backwards simultaneously and
the copping rail to be wound down; the worm wheels e, and ³, move together in
both directions.
On the worm wheel k¹, there is a cam projection k³, which when it comes round
acts upon a projecting arm ", from the slide bar 12, and moves it endways, and forces
-the bevel wheel g', out of gear with the wheel g, the look i¹, near the end of the bar ³,
being then in the position to catch upon the arm j, of the casting when it is moved
into the position to start the machine so that it will be held when the worm wheel k¹,
begins to rotate backwards and leaves it.
"
It will be noted that the slide bar 3, has a similar function to the rod i, figs. 1.and 2
as to bringing into gear of the wheels g', and g, but it also performs-the function of
the rod h, figs. 1 and 2.
Fig. 5 is a front elevation partly in section of the cam mechanism for holding and
releasing the sliding barj, on an enlarged scale and fig. 6 is an end view of the cam
cover. plate. on a large scale. j, is the sliding bar, the projection in its side;
f; the vertical bar, sliding in holes in the bracket a;, is the finger jointed at ƒ³,
to the vertical bar, and 6, is the weighted tail part of the finger.
fis the bowl on a stud in the lower end of the bar f*, that fits the groove of the
cam f; f, is a cover plate at the front of the cam, secured to it by screws as
shown.
This arrangement prevents the mechanism from being tampered with.
The arrangement of mechanism shown by figs. 5.and 6 may be used with other
combinations of mechanism for stopping a ring frame when the "set" is full.
The mechanism described may be varied, for instance the cam ƒ³, may be made
to lift the vertical slide, instead of drawing it down more and more as the cops
or spools build. A tumbler catch may be jointed to the sliding bar j, to catch
upon the vertical slide fƒ³.
The cam, may also be made to act upon a lever instead of a slide f³.
The mechanism described for automatically stopping the machine when a
"
set"
is full (see figs. 5 and 6) may be used alone, without using the mechanism for
winding down the copping rails automatically.
Fig. 7 is an end elevation partly in section, and fig. 8 is a side elevation of the
end of a ring frame illustrating another combination of mechanism for carrying

page_text: out our invention applied to machines where the ring or copping rails are lifted
by levers 7, acting upon vertical rods or pokers in a well known manner.
In this system it will be seen that the chain e³, from the pulley e³ on the heart
wheel or cam lever d, passes to a pulley m, on a stud attached to the framing,
and then from another pnlley m³, (secured to or forming a part of the pulley m)
a chain m³, passes, the other end of which is connected with a segment ", forming
one arm of the ordinary lifting lever l.
As the copping or ring rail, lifts higher and higher as the cops build an
adjustable screw projection 12, upon an arm from the lifting lever arm A, comes
nearer and nearer, and at last catches upon the short arm of a lever n, having its
fulcrum n', carried upon the heart wheel or cam lever d³, so as to cause the
mechanism to stop the machine as hereinafter explained.
We will first describe the mechanism carried upon the heart wheel or cam
lever d².
There is a shaft p, in bearings upon the lever d, its end is square to suit a key
for adjusting or winding the copping rail down.
Upon the shaft p, there is the ratchet wheel p', upon which a pawl p³, acts, that is
jointed upon a lever p³, free to oscillate upon the shaft p.
This lever or arm p³, can rest when the lever d', is above a certain level upon a
projection d. The free end of the arm p³, rests at one point in the descent of the
lever d², upon a pin p*, adjustable in a vertical slot in the bracket carrying the lifting
lever 1. By this arrangement the pawl may be made to take one or more teeth of the
ratchet at each oscillation of the cam lever d². p, is a retaining pawl jointed upon
the end of the lever d². This shaft p, has a small spur toothed pinion p, upon it,
that gears with a spur wheel g¹, loose upon a shaft 9, having bearings in the cam
lever d².
The boss of the wheel q', has clutch teeth upon it that gear with corresponding
clutch teeth upon a boss q, fast upon the shaft q, to which boss q', a long spur
pinion q³, is attached that gears with a spur wheel loose upon the shaft p, this last
named wheel 9, has the boss or pulley e, formed upon it to which one end of the
jointed chain e³, is attached.
The shaft to which one part of the clutch q², is secured is arranged so that it
can be slided endways, and when slided inwards that half of the clutch, attached
to it, is separated from or is put out of gear with the other half of the clutch on the
boss of the wheel q', which is arranged not to slide endways.
There is a flat spring q, one end secured to the cam lever d³, the other end acting
upon the shaft g, to force it endways, and the clutches out of gear.
In the position in which the gearing is shown in fig. 7 the rotation of the shaft p,
by the key handle will rotate the wheel q, and the pulley e, connected with its boss.
But when the shaft q, is moved endways, and the clutches (9³) are thus out of
gear the wheel q*, can be rotated without rotating the ratchet wheel pl, on the shaft
so that it is not necessary to remove the pawl p³, or retaining pawl p, when winding
back the copping mechanism.
P,
Upon the inner end of the shaft g, a bevel wheel 98, is secured, which as shown in
fig. 7 is out of gear with a bevel 98, (constantly rotating) upon the lower end of a
vertical shaft, . but when the shaft q, is forced endways by the flat spring g' the
wheels go, and g³, come into gear.
The lower bevel wheel ge, is in a bearing jointed at 97, to the cam lever d², and the
upper end of the shaft g, slides in the boss of a bevel wheel 9, (with which it is
.connected by a key and key groove) the bearing for the boss of which bevel wheel g₁,
oscillates slightly round the axis or boss for the bearing of the axis of the constantly
rotating bevel wheel g, with which it gears, these arrangements thus permit of slight
oscillations in the vertical shaft gº.
The action of the flat spring, to throw the clutch q², out of gear is prevented by
the said lever n. Que arm of the lever n, comes behind the shoulder or back of the
clutch q, fast upon the shaft g, and prevents it from moving end ways, but when the
lever, is lifted clear of the boss, the flat spring q³, can act to force the clutch q³, out

page_text: of gear, and the bevel wheel 98, into gear, and when the wheel q, has been turned
back to the required extent, a cam incline 97, (which may be made adjustable) acts:
upon the shoulder of the clutch q, fast upon the shaft and forces it forwards against
the action of the spring 9, when the lever arm n, falls by its own gravity and.thus.
holds the clutches in gear. When the long arm of the lever n, lifts, its end comes
against the end of an adjustable set screw, in one end of a bent lever r, having its
fulcrum, upon the framing a, the end of the lever r, forming a catch for the lower
end of another lever r³, on a fulcrum at r, the upper end of which rests against a
stud c, in the end of the belt guide slide c.
To the vertical lever, one end of a chain ³, is attached which passes over a
pulley j, upon a stud, there being a weight, upon the other end of the chain, that
will move the lever, and belt guide slide c, when the lover catch T, is released.
When the lever n, is arranged to act only upon the screw ', in the lever
mechanism will then only stop the machine, and the copping mechanism may be
wound down by hand.
