Improvements in Mechanism for Separating Yarns being Spun by
Adjacent Spindles in Spinning Frames.
A communication from abroad by WILLIAM FRANKLIN DRAPER, of Hopedale,

States of America, Manufacturer.
I ALFRED GEORGE BROOKES of 55 and 56 Chancery Lane in the County of
London, Chartered Patent Agent, do hereby declare the nature of this invention
to be as follows:-
In modern spinning frames the spindles are run at such bigh speed that the
yarn is very apt to "balloon," as it is called, in which event, the yarns being spun
by adjacent spindles strike and break down ends. To obviate the yarns striking
each other, separators are employed between adjacent spindles, and these separators
have to be so supported that they may be raised and lowered substantially in
unison with the ring rail and also so that they may be turned out of the way when
the bobbins are to be doffed from the spindles.
In this invention the separators are so supported that when the bobbins are
to be doffed the separators may be thrown downwardly and backwardly away from
the ring rail or be thrown upwardly and backwardly from the ring rail and under
the guide board.
In this invention the pivot or centre from which the arc of movement of the
separators, as a whole, is described, is so placed that the force required to move the
separators is lessened.
This invention consists in the use with a spinning frame having a ring rail and
rings, and a spindle rail and spindle, of a carrier having attached to it a series of
broad separator blades, the carrier being so mounted on its supports that a partial
rotation of the said carrier toward the front of the frame effects a novement of
the separator blades downwardly between the carrier and the ring rail, and
backwardly out from between the spindle, substantially as will be described.
Also in the use with a spinning frame and its spindles, of a guide bar or carrier
having a series of broad separator blades mounted thereon, and movable supports
for said guide bar, said supports being adapted to permit the separator blades
preparatory to doffing the bobbins to be turned down and under the guide bar, or
up and over under the guide board, substantially as will be described.
Also in the use with a spinning frame, having a guide bar on which is mounted
a series of separators, of a lever having a pair of levers operatively connected
therewith, one of the levers of the pair serving as a support for the guide bar
while the other co-operates frictionally with the guide bar in its changed positions,
substantially as will be described.
Also in the use with a guide bar, and a clamp secured thereto, of a separator
pivotally mounted on said clamp, to operate substantially as will be described.
Also in the use in a spinning frame, having a roller beam, a series of spindles, a
ring rail, and a series of rings, of a guide bar having a series of separators, the
guide bar being mounted on levers, the main lever having its pivot back of the
front of the roller beam, whereby the separators may be turned down under and
back or up over and back, substantially as will be described.

page_text: To facilitate description I will refer to a roller beam, a spindle rail; a rising
and falling ring rail having rings, a spindle; a bobbin; andra guide board, all of
which may be of usual construction.
The roller beam has connected to it a stand having joined to or forming part of
it a leg having a fulcrum stud or rod, on which are pivotally mounted two levers
one, the main lever having preferably a counterbalancing weight, a suitable pin or
projection on the stand determining the distance that the respective levers may
descend under the weight of the separators described hereinafter.
I herein refer to certain parts in the singular, but it will be understood that
they are duplicated at the other end of the machine to that which is being
described.
For example, there is a stand and a leg, levers, and fulcruin stud at each end of
the machine.
The separators may be slotted plates having feet each clamped by a screw and
block to a rotatable guide bar composed of say two rods extending across the
frame, one rod say the lower one, having its end supported by a notch, in the
secondary lever the other rod, the upper one, when the separator is in either of
its forward positions, having its end supported frictionally by the inclined face of
the auxiliary lever pivoted by a pin to the second lever the second and auxiliary
levers each having suitable holes for the reception of said pin, a pin projecting
from the auxiliary lever entering a slot in the second lever.
This construction enables the auxiliary lever to be tipped on the pin independently
of the second lever, and yet, at all times the auxiliary lever may be kept pressed
toward the guide bar to exert a yielding pressure thereon, as required, according
to the changed position of the guide bar carrying the separators.

"
Opposite the samsons or intermediate frames, or legs, especially when they
are near the ring rail, the separators have to be applied to the guide bars in a
different manner.
In accordance with this modification, the separator has an ear which is provided
with a hole to receive a pin at the upper end of a block provided with a screw
threaded hole adapted to receive a screw extended through a small block and
between the rods constituting the guide bar.
samson
Mounting the separators opposite the "samsons," enables the said separators to
be turned back with the guide bar but when the guide bar is turned over to the
backward position or down into the hanging position, the particular separator
simply drops and hangs against the "samson," and the contact with the "
does not interfere with the motion of the guide bar. The guide bar, near the
lever has clamped upon its opposite sides by screw, two blocks the one being
preferably somewhat longer and provided with a projection, which projection, when
the separator or guide bar is turned down and back strikes the upper end of the
auxiliary lever and causes the series of levers to assume and remain in a position of
retirement.
When the separators are turned up and back into a vertical position the
auxiliary lever is also acted upon, but this time by one of the rods of the guide
bar, and the main lever and the second and auxiliary levers are correspondingly
moved.
down.
In practice according to my. invention the separators may be turned up or
The centre of movement of the separators when moved by the ring rail is at a
point located back of the front of the roller beam.
Hitherto when separators have been so arranged on pivots as to be turned
thereon by or in unison with the movement of the rail, their pivots have been
placed in front of the roller beam and their action was through a much greater
arc requiring more power to turn them, and they were even turned so far as in
some cases to throw their centre of gravity on the other side of the pivot, requiring
positive mechanism to insure bringing them down.
By placing the pivots on the other side of the roller beam it is possible to make

page_text: sure that the separators can never turn too far as the front of the roller beam
itself limits their movement, and the centre of gravity cannot get over.
The rods to which the separators are adjustably secured form a rotatable carrier
for the separators.

I ALFRED GEORGE BROOKES of 55 and 56 Chancery Lane, in the County of
London, Chartered Patent Agent, 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 :-
In modern spinning frames the spindles are run at such high speed that the yarn
is very apt to "balloon," as it is called, in which event, the yarns being spun by
adjacent spindles strike and break down ends. To obviate the yarns striking each
other, separators are employed between adjacent spindles, and these separators have
to be so supported that they may be raised and lowered substantially in unison
with the ring rail and also so that they may be turned out of the way when the
bobbins are to be doffed from the spindles.
In this invention the separators are so supported that when the bobbins are to be
doffed the separators may be thrown downwardly and backwardly away from the
ring rail or be thrown upwardly and backwardly from the ring rail and under the
guide board.
In this invention the pivot or centre from which the arc of movement of the
separators, as a whole, is described, is so placed that the force required to move the
separators is lessened.
This invention consists in the use with a spinning frame having a ring rail and
rings, and a spindle rail and spindle, of a carrier having attached to it a series of

rotation of the said carrier toward the front of the frame effects a movement of
the separator blades downwardly between the carrier and the ring rail, and

baving a series of broad separator blades mounted thereon, and movable supports
for said guide bar, said supports being adapted to permit the separator blades
preparatory to doffing the bobbins to be turned down and under the guide bar, or

series of separators, of a lever having a pair of levers operatively connected
therewith, one of the levers of the pair serving as a support for the guide bar
while the other co-operates frictionally with the guide bar in its changed positions,
substantially as will be described.
Also in the use with a guide bar, and a clamp secured thereto, of a separator
pivotally mounted on said clamp, to perate substantially as will be described.

Also in the use in a spinning frame, having a roller beam, a series of spindles, a

page_text: ring rail, and a series of rings, of a guide bar having a series of separators, the
guide bar being mounted on levers, the main lever having its pivot back of the
front of the roller beam, whereby the separators may be turned down under and
back or up over and back, substantially as will be described.
Fig. 1 shows in section a sufficient portion of a ring spinning frame with my
improvements added to enable my invention to be understood, the ring rail being
down, the view being taken from the left of the dotted line x, Fig. 5.
Fig. 2 is a similar view with the ring rail elevated.
Fig. 3 shows the ring rail down and the separator turned up and back preparatory
to doffing.
Fig. 4 is a like view with the separator turned down and back for doffing.
Fig. 5 is an elevation of the parts shown in Fig. 1 looking in the direction of
the arrow 1.
Fig. 6 is a partial section, the view being taken from the right of the dotted
line Fig. 5.
Figs. 7 and 8 are sectional views, looking to the left of line from the right
hand side of Fig. 5 and showing the separator m in two different positions.
Figs. 9, 10, 11 and 12 are details to be referred to.
In the drawings A represents part of the roller beam, and Ax the front of the
same; B a spindle rail; B' a rising and falling ring-rail having rings B³, B³ a
spindle B a bobbin; and B a guide board, all of which are and may be of
usual construction.
;
The roller beam has connected to it a stand A¹ having joined to or forming part
of it a leg A having a fulcrum stud or rod a, on which are pivotally mounted two
levers b, c, the main lever b having preferably a counterbalancing weight b', a
suitable pin or projection a¹ on the stand determining the distance that the
respective levers b and c may descend under the weight of the separators d to be
described hereinafter.
Since Figs. 1, 2, 3, 4 and 5 of the drawings show only one end of the machine,
I herein refer to certain parts in the singular, but it will be understood that they
are duplicated at the other end of the machine, to that which is being described.
For example, there is a stand corresponding with stand A', and similarly a leg A³,
levers b, and c, and fulcrum stud a, at each end of the machine.
The separators d are shown as slotted plates having feet d' see Fig. 6 ench
clamped by a screw d² and block d³ to a rotatable guide bar d composed as
shown, of two rods extending across the frame, one rod, herein shown as the lower
one, having its end supported by a notch 2, see Fig. 9, in the lever c, the other
rod, the upper one, when the separator is in the positions, Figs. 1, 2, 3 and 5,
having its end supported frictionally by the inclined face 3 of the auxiliary lever e,
pivoted by a pin e¹ to the lever c, the levers e and c each having suitable holes 4, 5,
for the reception of said pin, a pin 6 projecting from the auxiliary lever e entering
a slot 7 in the lever b, shown by full lines Fig. 3, and by dotted lines Figs. 1, 2
and 4. This construction enables the auxiliary lever e to be tipped on the pin el
independently of the lever c, and yet, at all times the auxiliary levere may be
kept pressed toward the guide bar to exert a yielding pressure thereon, as
required according to the changed position of the guide bar carrying the
separators.
Opposite the "
samsons or intermediate frames, or legs, f, especially when they
are near the ring rail, see Fig. 5, the separators have to be applied to the guide
bars in a different manner; Figs. 7 and 8, showing such different mounting in two
positions.
"
In Figs. 7 and 8, and at the right in Fig. 5, the separator there marked m has
an ear m¹ shown best in Fig. 8, which is provided with a hole to receive a pin h¹
at the upper end of a block 2 provided with a screw threaded hole adapted to
receive a screw extended through a small block and between the rods
constituting the guide bar.
Mounting the separators m as described opposite the "samsons," enables the

page_text: "
said separators to be turned back with the guide bar as in Fig. 3, but when the
guide bar is turned over to the left, viewing Fig. 7, or down into the position,
Fig. 8, the particular separator m simply drops and hangs against the "samson,'
and the contact with the "
samson does not interfere with the motion of the
guide bar. The guide bar, near the lever e, see left of Fig. 5 aud also Figs. 3, 4
and 11, has clamped upon its opposite sides by screw n, two blocks n, n³, the one
marked n², shown separately in Fig. 11, being represented as somewhat longer and
as provided with a projection n', which projection, when the separator or guide.
bar is turned down and back into the position Fig. 4, strikes the upper end of the
auxiliary lever e, and causes the series of levers to assume and remain in the position.
represented in that figure.
The projection n¹ is shown by dotted lines in Fig. 1.
When the separators are turned up and back, into position Fig. 3, the lever e is
also acted upon, but this time by one of the rods of the guide bar, and the lever b,.
and the levers cand e are made to assume the positions shown in Fig. 3
Figs. 1 and 2 show the working positions of the parts, the ring rail being down.
in Fig. 1, and up in Fig. 2. This is the first instance known to my correspondent
in which the separators may be turned up as in Fig. 3, or down as in Fig. 4.
for doffing.
As shown best in Figs. 1 and 2 the centre of movement of the separators when
moved by the ring rail is at a, a point located back of the front A× of the roller
beam A.
Hitherto when separators have been so arranged on pivots as to be turned.
thereou by or in unison with the movement of the rail their pivots have been
placed in front of the roller beam and their action was through a much greater are
requiring more power to turn them, and they were even turned so far as in some.
cases to throw their centre of gravity on the other side of the pivot, requiring
positive mechanism to insure bringing them down.
By placing the pivots on the other side of the roller beam it is possible to make.
sure that the separators can never turn too far as the front of the roller beam
itself limits their movement, and the centre of gravity cannot get over.
The rods d to which the separators are adjustably secured form a rotatable-
carrier for the separators.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The use with a spinning frame having a ring rail and rings, and a spindle rail
and spindle, of a carrier having attached to it a series of broad separator blades,.
the carrier being so mounted on its supports that a partial rotation of the said
carrier toward the front of the frame effects a movement of the separator blades
downwardly between the carrier and the ring rail, and backwardly out from
between the spindle, substantially as described.
2. The use with a spinning frame and its spindles, of a guide bar or carrier
having a series of broad separator blades mounted thereon, and movable supports
for said guide bar, said supports being adapted to permit the separator blades
preparatory to doffing the bobbins to be turned down and under the guide har, or
up and over under the guide board, substantially as described.
3. The use with a spinning frame, having a guide bar on which is mounted a
series of separators, of a lever having a pair of levers operatively connected
therewith, one of the levers of the pair serving as a support for the guide bar
while the other co-operates frictionally with the guide bar in its changed positions,
substantially as described.
4. The use with a guide bar, and a clamp secured thereto, of a separator
pivotally mounted on said clamp, to operate, substantially as described.
5. The use in a spinning frame, having a roller beam, a series of spindles, a ring
rail, and a series of rings, of a guide bar having a series of separators, the guide-

the roller beam, whereby the separators may be turned down under and back or
up over and back, substantially as described.
