Year: 1884

page_text: I HENRY BIRKBY, ARUNDEL, of the City of Manchester, in the County of
Lancaster, Machinist, do hereby declare the nature of said invention for IMPROVE-
MENTS IN MACHINERY FOR PREPARING OR CALENDERING YARNS OR THREADS IN
THE HANK," to be as follows :—
My improvements are made upon machines for calendering or preparing yarns
or threads in the hank, and the object of my invention is to stop the operation or
throw the machine out of gear when the operation is completed by automatic
means, and in some cases also to ring a bell at the same time.
One of the ordinary machines consists of an upper roller in stationary bearings
with two paper or cotton bowls one under the other and under the upper roller.
The paper or cotton bowls are in bearings so as to move up and down vertically
and be pressed against the upper fixed roller.
The middle roller or bowl rotates on a stationary or non-rotating shaft which is
jointed on one side on a vertical axis, so that the bowl can be turned to one side to
remove and replace the hanks, and this non-rotating shaft is secured in its placó
when operating by a latch or other. means..
By a worm on the shaft of the upper roller gearing with a worm wheel on a shaft
in a bracket and another worm upon this shaft gearing with a sliding rack, the latter
is lifted as the operation proceeds, and at any point fixed upon it is made by an
adjustable finger to ring a bell to give notice that the operation is finished.
One modification of my invention consists in arranging a projection on the rack
which will lift the latch when required and thus allow the action of the machine to
swing the non-rotating shaft clear of the other rollers and thus stop the calendering
operation.
Another modification of my invention consists in causing a rack or other
mechanism to come into action and force the two paper or cotton bowls out of
contact with the driving roller and thus stop the operation when the yarn or thread
has been sufficiently calendered.
Another modification consists in stopping the rotation of the entire machine, by
causing the rack or other equivalent mechanism to traverse the driving belt or
throw a clutch out of gear.
The mechanism to act upon the latch and the latch itself may be arranged in a
variety of ways a toothed segment, wheel and pin or notched disc or other
arrangements being used in place of the toothed rack and connected mechanism.

Lancaster Machinist, do hereby declare the nature of said invention for IMPROVE-
MENTS IN MACHINERY FOR PREPARING OR CALENDERING YARNS OR THREADS IN
THE HANK," and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
My improvements are made upon machines for calendering or preparing yarns
or threads in the bank and the object of my invention is to stop the operation or
throw the machine out of gear when the operation is completed by automatic means,
and in some cases also to ring a bell at the same time.
One of the ordinary machines consists of an upper roller in stationary bearings
with two paper or cotton bowls one under the other and under the upper roller.
The paper or cotton bowls are in bearings so as to move up and down vertically
and be pressed against the upper fixed roller.
The middle roller or bowl rotates on a stationary or non-rotating shaft which is
jointed at one side on a vertical axis so that the bowl can be turned to one side to
remove and replace the hanks and this non-rotating shaft is secured in its place
when operating by a latch or other means.
Sometimes I arrange the middle roll with pivots that rotate in a frame which
can be turned to one side same as the stationary axis.
By a worm on the shaft of the upper roller gearing with a worm wheel on a
shaft in a bracket and another worm upon this shaft gearing with a sliding rack,
the latter is lifted as the operation proceeds, and at any point fixed upon it is
Inade by an adjustable finger or stud to ring a bell to give notice that the operation
is finished.
One modification of my invention consists in arranging a projection on the rack
which will lift the latch when required and thus allow the action of the machine
to swing the non-rotating shaft or the frame carrying the pivots of the middle
bowl clear of the other rollers and thus stop the calendering operation.
Another modification of my invention consists in causing a rack or other
mechanism to come into action and force the two paper or cotton bowls out of
contact with the driving roller and thus stop the operation when the yarn or thread
has been sufficiently calendered. .
Another modification consists in stopping the rotation of the entire machine by
causing the rack or other equivalent incchanism to traverse the driving belt or
throw a clutch out of gear.
The mechanism to act upon the latch and the latch itself may be arranged in a
variety of ways a toothed segment wheel and pin or notched disc or other
arrangements being used in place of the toothed rack and connected mechanism.

•
A is the framinga is the upper bowl in stationary bearings. It is driven by
a belt working on a driving pulley (not shown) placed on its shaft or axis a
one side.

page_text: b (shown in dotted line) represents the lower bowl, it has pivots which have
bearings in a frame formed by two sides and a connecting cross bar b¹ and this
frame is arranged to slide up and down in vertical guides on the two side frames
of the machine and the middle of the cross bar b' rests upon one end of a lever b²
which has its "knife edge" fulcrum 63 on a stand bracket on the framing―The
other end of the lever 63 is connected by an adjustable rod b' with a weight.Jever b
having its fulcrum 6º adjustable in a bracket A' on the floor and the end of the
weight lever bis acted upon by an adjustable stud 6' in a foot lever 6ª having its
fulcrum b on the framing.
The weight 610 (shown in dotted line) is adjustable on the lever b.
When the treadle end of the foot lever 68 is depressed it can be held down, so as
to keep up the weight lever bo by a catch b* jointed on the framing which will
hook upon the projection from the lever for the foot.
When the weight on the lever 65 descends the frame carrying the pivots of the
lower bowl b is lifted and is forced against the middle bowl c and the latter against
the
upper bow! a
and when the treadle lever bis depressed and held down the
weight lever b is lifted and the lower bowl b is withdrawn from the middle
bowl c.
In figs 1 and 2, the middle bowl c (which is sometimes arranged to rotate on a
stationary axis) is shown with pivots that have bearings in a frame c¹ which at one
side is carried on and secured to a vertical shaft c³ that has bearings in brackets
secured to the side frames.
This shaft c can slide up and down vertically in its bearings and it is adjusted
by a set screw in its lower bearing acting on the end centre of the shaft.
The frame c¹ has a handle by which it can be turned on its axis c² and a
projection for the hook hereinafter mentioned to catch upon.
It has also a projection c³ having a slot for an adjustable stud c that forms the
fulcrum of a three armed lever. One arm c' of the latter carries a stud forming
the axis of a bobbin or roller c³ free to rotate upon it, the second arm c³ is for an
adjustable weight, and the third arm c* is for an antifriction bowl, which when the
frame swings out will come against the cam shaped face of a bracket c¹º secured to
the side frame.
When the bank is being operated upon it extends as shown by the dotted line d
from the middle bowl c'to the bobbin c and it is kept stretched by the weight on
the arm while the bars c¹¹ on the frame (c¹) act as guides to keep the hanks from
spreading too far on the bowl c.
At the completion of the operation the frame c' swings outwards (carrying the
bowl c with it) towards the position shown in dotted line in fig 2 and at the same
time the bowl on the arm c* comes against the cam surface on the bracket c¹0 and
this brings the bobbin towards the bowl c (as shown in dotted circles in fig 1)
and leaves the hank slack so as to be readily removed and ready for another to be
placed for the next operation the frame c¹ being then put back and latched in the
operating position of the parts as shown in fig 1.
The hook latch e which takes hold of the projection c on the frame c¹ is jointed
on a stud e¹ on the side of the framing, and on the same stud the fulcrum of a
toothed segment e³ is placed, which has a slot in it for an adjustable stud e³.
The teeth of this segment e gear with a worm e fast on the lower end of a
ahaft having its bearings in a tubular part e which is jointed at its upper end at e*
to a bracket secured to the framing, the upper end of the shaft in the tubular part
having a worm wheel e' secured on it gearing with a worm a¹ on the end of the
axis of the upper bowl a.
Thus arranged the tubular part №³ can oscillate on its joint and bring the
worm e at the lower end of its shaft out of gear with the toothed segment e¹ and
this takes place when the hook latch e, is released, as one end of a spring e secured
to the framing is constantly acting against the tubular part e to push it from
the toothed segment e when the frame c' is in the operating position.

page_text: 33
The worm e' is held in gear with the toothed segment c² and against the
pressure of the spring by the projection et on the frame c¹ which comes against a
projection e on the lower part of the tubular bearing e³.
When the operation upon the hank commences the worm c' and toothed
segment e² are brought into gear (the toothed segment being then in its lowest
position) and after any given or required number of revolutions of the bowl
(which is or can be determined by the position of the adjustable stud e³ and an
index on the segment) the stud e will have come in contact with the under side of
the hook e and will begin to lift it and will thus release the hook from the pro-
jection on the frame c' when the hank has been under operation during the
required number of revolutions (or thereabouts) at which moment the frame c¹
swings out by the rotary motion and pressure on the bowls towards the position
shown in fig 2 ready for the hank to be changed.
When the toothed segment e² is released from the worm ex it falls and strikes.
against an arm e* attached to the spring of a bell eo tho stud carrying which is
fixed in a bracket on the framing.
The same result is produced when the spring to which the bell is attached is
secured to the arm of the toothed segment e as shown in dotted line in fig 1.
The toothed segment e³ in falling strikes as before stated against the arm e*, and
the latter rests against a stud or other arrangement below it carried on the
framing which acts as a stop for the lowest position of the toothed segment and is
required as a stop when the bell is arranged as shown in dotted line in fig 1.
Fig 3 shows how a straight toothed rack may be substituted for the segmental
rack. The straight rack c² is arranged to slide vertically in uides e" and the
spring for the bell is secured to the lower end of the rack and rings when the
latter falls against the stop which may be the lower guide e c in this case
shows the end of a stationary axis (when used) for the bowl c, and corresponds to
the projection et on the frame c¹.
Fig 8 illustrates an alternative arrangement of the mechanism for releasing the
frame c' or stationary shaft for the bowl c-A forked lever piece is arranged on a
fulcrum in a bracket h² secured to the framing, and the lutch e (corresponding to
the latch e fig 1) hooks upon one prong of the fork h.
The fork holds the round end of the projection from the frame c' or the end of
the stationary axis for the bowl c, when used, and when the hook e releases the
fork it assumes the position shown in dotted line (where the tail part h³ comes
against the framing) and allows the end of the shaft or projection c³ to escape-
The part of the fork comes against the projection e' on the tubular bearing.
Figs 4 and 5 show how my invention is carried into effect by wedges or parts
brought between the margins of the middle and upper bowl so as to separate them
and stop the calendering action upon the hank. The mechanism is the same as
that herein before described and shown in figs 1 and 2 except as follows-There is
a shaft above the upper bowl a having bearings with slight play in brackets
secured to the side frames--This shaft f has two arms f¹ secured to it the lower
ends of which have each a side projection f¹ coming over the margin of the
bowls a and c.
Theso projections when allowed will also come opposite the junction or point
where the two bowls come in contact and will be drawn in by the bite of the
bowls until they come against a stop or stops on the framing and will thus act to
come between and separate them.
There is an arın ƒ³ on one end of the shaft which has a projection f' to come.
into a notch on the underside of a lever c (on a stud in the framing) corresponding
to the hook latch e fig 1 and when this lever or latch is lifted by the stud in the
toothed segment e² the arm f³ is released and the shaft foscillates by the weight of
the arms and brings the projections f³ into the position to separate the bowls.
Figs 6 and 7 show an arrangement to stop the operation upon the hank by
guiding the driving belt from the fast to the loose pulley-The driving pulleys g

page_text: are supposed to be on the shaft at one end of the upper bowl a and at the other
side of the machine the toothed segment e² and other parts are arranged the same
as hereinbefore described and shown in fig 1 with the following exceptions. -g is a
bracket secured to the framing which carries the stud e¹ for the fulcrum of the
toothed segment and also for a bent levere one end of which is guided but is free
to move in a slot g² in the bracket g¹ this end projecting through the slot in the
bracket into a slot g³ in a lever g' having its fulcrum on a stud in the bracket g¹.
The upper end of the lever g (shown broken away in fig 6) is connected by a
rod g with the belt guide of a lever g³ corresponding with the lever g and having
its fulcrum on a stud in a bracket secured to the framing in a similar manner to
the lever g* on the stud go but on the opposite side of the machine this last named
lever g³ having the belt guide 9º secured to it consequently the lever g* on one side,
and the belt guide lever g³ on the opposite side of the machine move together.
There is also a weight or spring (not shown) acting constantly upon the belt
guide lever to move it so as to traverse the belt from the fast to the loose pulley
When the belt is moved on to the fast pulley the projecting end of the bent levor e
catches upon the notch g³ and holds the belt guide in that position against the
action of the weight or spring, but when one arm of the lever e is lifted by the
stud e³ in the toothed segment e the other end of the lever e is depressed and
releases the lever and allows the weight or spring to traverse the belt and stop
the operation.
To make the mechanism more exact in stopping the operation or machine the
worm & on the lower end of the shaft in the tubular part is secured to it by a
screw and washer with leather between the washer and boss of the worm so as to
secure the worm against a shoulder on the shaft by friction sufficient to carry it
round and lift the toothed segment e² and hook Intch e but so that the rotation of
the worm can be arrested when required while its shaft continues to revolve-(any
other friction arrangement for driving the worm may be used for effecting the
object instead of the washer and leather)-The boss of the worm ef has a projection
from it which when the tubular part e is moved to release the toothed seginent c²
will come in the way of a stop projection on the framing or in a bracket on the
framing which will prevent the worm from revolving when the projection arrives
in contact with the stop but will relcaso it and allow it to begin to revolve again
when the tubular part e³ is pushed back to bring the worm into gear again with
the toothed segmont e-The object of this arrangement is to stop the rotation of
the worm e* and retain it in the arrested position where its worm or teeth will
come exactly opposite and gear with those of the toothed segment e³ when in its
lowest position.
According to another modification of my invention the fulcrum for the tubular
parte is moved further from the worm a' on the axis of the upper bowl so that
when it oscillates to release the lower worm ct from the toothed segment e³ it will
also bring the worm wheel e' by the same movement out of gear with the worm a¹
on the upper bowl, and thus both worins a' and e' by oscillating the tubular part
will be simultaneously thrown out of and into gear.
If the Index stude³ is set with this arrangement to disengage the worm e' at
the same point of its revolution it will go in and out of gear tooth for tooth at the
same point of its revolution-To ensure the throwing out of gear of the two
worms a¹ and e¹ when the worm shaft has arrived at the same part of its rotation
a disc is fixed on the shaft or formed on the boss of the worm e' or worm wheel e³,
on the latter by preference this disc having a notch which a projection fixed on the
framing will enter when the notch in the disc comes round opposite to the
projection when the part e is released.
The stop or projection is placed on that side towards which the tubular part e³ will
move the disc when throwing the worms out of gear. With this arrangement, when
the hook latch c is released the tubular part e will not be able to oscillate until the
disc has completed so much of its rotation as will be required to bring the notch in
the disc opposite the projection as until that moment the edge of the disc will act
с

page_text: against the end of the projection and provent the tubular part being oscillated
by the spring, but when it comes opposite the notch the spring e or its weight if
so arranged will force the tubular part and thus the disc towards the projection
and throw both worms out of gear. The bell in the last described arrangement
inay be attached to the frame (c¹) or to a part acted upon or released when the
frame c is released by the hook latch e and moves it.
Other modifications of mechanism may be used in place of those herein before
described for releasing the stop mechanism without departing from my invention.

invention and in what manner the same is to be performed, I declare that what
