Improvements in Machines for Balling or Winding Slivers of
Fibrous Material.
I, WILLIAM BROADLEY LEE, of Providence Iron Works, Bradford, in the
County of York, Machine Maker, do hereby declare the nature of this invention
to be as follows:
This invention particularly relates to improvements in that class of machine
for balling, that is to say winding in the form of a cheese, slivers of fibre pre-
paratory to combing, such as the machine for which Letters Patent No. 11668
were granted to me on the 27th day of August 1887.
I mount the balling disc, through which the balling spindle is withdrawn to
release the ball, upon the end of a sleeve surrounding said spindle and the other
end of this sleeve abuts against a collar and both are fitted into an external sleeve
adjustably fixed in an eye or socket formed in a side standard which latter may
be fixed upon a box bed. The sleeve carrying the balling disc is confined laterally,
so far as outward movement is concerned, by the said collar, and, to relieve the
pressure of the disc upon the ball preparatory to removing it, an inclined slot is
made in the external sleeve and a projecting handle or lever fitting this slot is
fixed to the collar, therefore when this handle is turned in a certain direction, to
partly rotate the collar, the inclination of the said slot forces this collar outwards
and leaves the sleeve and disc free to follow it. A guard for enclosing the toothed
wheels driving the disc is mounted on the inner end of the said external sleeve.
The spindle of the other balling disc revolves in a sleeve adjustably mounted in
an eye or socket formed in the other side standard and a guard enclosing the
driving wheels is fixed on the inner end of such sleeve.
To maintain and regulate the pressure of the presser plate upon the ball as it
is built up we employ a cone friction device or modified cone clutch on the presser
shaft. One cone, say the male cone is connected to the side frame in any con-
venient way to prevent it rotating and the female half of the clutch is keyed or
mounted upon the shaft in such a way that it is carried round with it but it is
free to slide towards or away from the fixed male cone. A screw thread is
formed on the end of the shaft upon which a flanged nut is mounted to bear
against the female cone and press it towards the male cone to retard the move-
ment of the presser plate and maintain its pressure upon the ball. To regulate
this pressure an adjustable arm or projection is secured to the flange of the nut
and a fixed stop is provided to engage this projection and limit the amount the
nut is turned. A spiral spring may be introduced to press the conical faces away
from each other when the nut is reversed to release the presser plate, and a weight
may be arranged to automatically bring the presser plate, after it is released, into
position for commencing a new ball.
To reduce the speed of the rotation of the ball when it has attained a certain

page_text: diameter I fix a bevel wheel on the driving shaft which wheel is hereinafter
termed the "fixed sun wheel" and I employ a driving pulley loosely mounted
upon said shaft and carrying upon a radial stud a bevel "planet" wheel the teeth
of which engage the fixed sun wheel. A loose sun wheel" engaging the planet
wheel diametrically opposite the fixed sun wheel is mounted upon a loose sleeve
on the driving shaft having a ratchet wheel fixed upon its inner end, which may
extend through a bearing bracket supporting the shaft.
"
Whilst the foundation of the ball is being formed a pawl lever engages this
ratchet wheel and prevents it revolving consequently the driving shaft revolves
at twice the speed of the driving pulley but when the ball has attained a certain
diameter a lever on the shaft or its equivalent carrying the presser plate" dis-
engages the said pawl lever from its ratchet. A spring presser or its equivalent
may be provided on this lever adapted to instantaneously disengage the pawl
lever as soon as it commences to move it. Provision may be made for regulating
or adjusting the time when the speed of rotation of the ball is changed. The said
planet wheel is provided with ratchet teeth engaging a spring pawl or stud in
the driving pulley which are adapted to prevent the planet wheel from back-
ward rotation consequently the two run wheels and the driving shaft are, as soon
as the pawl lever is released from the ratchet wheel driven at the same speed as
the driving pulley.
Other forms of "sun and planet" motion may be employed which may be
arranged to give greater or less variation in speed and instead of forming ratchet
teeth on the planet wheel other provision may be made for locking the said
ratchet wheel at the slower speed.
A loose pulley may be provided for the belt.

Improvements in Machines for Balling or Winding Slivers of
Fibrous Material.
I, WILLIAM BROADLEY LEE, of Providence Iron Works, Bradford, in the
County of York, Machine Maker, 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; -
This invention particularly relates to improvements in that class of machine
for balling, that is to say winding in the form of a cheese, slivers of fibre pre-
paratory to combing, such as the machine for which Letters Patent No. 11668
were granted to me on the 27th day of August 1887.
In the accompanying drawings Figure 1, represents an end elevation of my
improved machine. Figure 2, is a side view partly in section. Figures 3, 4
and 5, are views of detail hereinafter referred to.
I fix the balling disc A through which the balling spindle B is withdrawn to
release the ball upon the end of the sleeve A² surrounding the spindle and the
other end of this sleeve abuts against the collar A3, and both the collar and sleeve
are fitted into an external sleeve A+ adjustably fixed by the set screw A in a
hole made to receive it in the top of the standard C fixed upon the box bed C².
The sleeve A2 is confined laterally, so far as outward movement is concerned by
the collar A3 and this collar has a hand lever A6 projecting through the inclined

page_text: slot A formed in the external sleeve A. Figure 3, represents a separate plan
view of the sleeve A. To relieve the pressure of the disc upon the ball pre-
paratory to removing it the handle A is moved from the position shown in the
slot A to the other end of the slot, this forces the sleeve outwards and leaves the
disc free to be pressed outwards by the pressure of the ball. A guard 1) for
enclosing the disc driving wheel D and its driving wheel D³ is mounted upon
the inner end of the sleeve A. The spindle E of the other balling disc 1 is
mounted in a sleeve bearing E³ fixed by the set screw in a hole formed in the
top of the standard C3 fixed upon the bed C². A guard 1 fixed upon the inner
end of the sleeve E is provided to enclose the wheel D³ driving the disc Eas
well as its driving wheel D. The wheels D3 and 16 are fixed upon the driving
shaft mounted in bearings formed in the standards C and C. The outer end
of the spindle B is cut with a screw thread and the hand wheel 133 fitting thereon
is screwed against the cap A8 to facilitate starting the withdrawal of the spindle.
The square inner end B2 of the spindle fits a square hole formed in a metal disc Aº
sunk in to the face of A.
To maintain and regulate the pressure of the presser plate G upon the ball as
it is built up I employ the cone plate H fixed to the standard C by a strong stud S
and surrounding the presser plate shaft G with the annular male cone H² con-
centric with the shaft. The female cone plate H³ fitting the male cone plate is
keyed by the key G³ to the shaft G2 but is free to slide thereon and the flanged
nut H screwed on to the end of G2 is provided to bear against the female cone
To enable the
and force it with the required pressure against the male cone.
pressure to be quickly removed and be readily brought back again to the same
pitch the arm H is adjustably fixed upon the nut H by the screws H, H and a
fixed stop H7 projecting from the cone H3 is provided and the arm H is brought
against this stop each time the pressure is applied. A spiral spring H8 is fixed
between the cone plates to press the plate H³ outwards to disengage the conical
faces when the pressure of the nut H is removed.
To reduce the speed of rotation of the ball when it has attained a certain
diameter I drive it through the medium of a sun and planet motion enclosed
within the driving pulleys. This motion consists of a bevel wheel J fixed on the
driving shaft F, a bevel wheel J2 mounted on a radial stud F2 fixed in the rim
of the driving pulley 13 and engaging the wheel J, and a bevel wheel J' loosely
mounted on the shaft F and engages the wheel J². The wheel J is fixed on the
sleeve J extending through the bearing bracket C fixed to C3 and carrying on
its inner end a ratchet wheel J. Whilst, say, the first half of the ball is formed
the pawl K mounted on the fixed stud K2 holds the ratchet wheel J, the sleeve J³
and the wheel J' stationary consequently as the pulley F3 revolves the wheel Ja
is driven by it, and the wheel Je drives the wheel J and the driving shaft Fat
twice the speed of the pulley. When however the ball has attained a certain size
the arm L on the presser shaft engages the extension K3 on the pawl K and thereby
disengages it from its ratchet as shown by the broken lines in Figure 5. The
wheel J is then no longer driven round on its stud F2 but as the wheel J2 has
ratchet teeth a formed on its back continuously engages by the spring pin or
pawl J3 mounted in a radial hole in the pulley the wheel J is prevented from
turning in the reverse direction to that in which it was driven by the wheel J'
therefore the wheel J2 drives the wheel at the same speed as the pulley F3.
Figure 4, is a section on the line a Figure 2 showing the interior of the
pulley E.
A pin L is preferably provided in the arm L with a spring L³ behind it tend-
ing to press it outwards, and when this pin first engages K³ the pin is pushed
inwards thereby compressing the spring until the pressure is sufficient to dis-
engage the pawl K from the tooth in the ratchet wheel with which it is engaged,
then the spring expands and instantaneously moves the pawl quite clear of the
ratchet wheel.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. The combination with the plate A having a bearing sleeve A², fitting an
external sleeve A, of the collar A³ having a handle A projecting through an
inclined slot A7 in A4, substantially as herein shown and described and for the
purpose specified.
2. The combination with the presser shaft G2 having a friction cone H³
mounted thereon to engage the fixed cone H, of the nut H+ having the lever H5
or its equivalent adjustably fixed to said nut, and a stop H7 adapted to engage
the lever H, substantially as herein shown and described and for the purpose
specified.
3. An arrangement for driving the head and spindle of a balling machine com-
prising a sun and planet motion and means for automatically throwing said
motion out of action to decrease the speed, substantially as herein shown and
described.
