Improvements in Apparatus for Winding Balls of Fibre for Combing
Machines.
We, MICHAEL FIRTH, JOHN KNOWLES and ISAAC HALSTEAD, of the firm of
M. Firth & Co. of Bolton Woods Shed, Frizinghall, Bradford in the County of
York, Machine Wool Combers, and JOSEPH ROBERTSHAW, of the same place,
Combing Overlooker, do hereby declare the nature of this invention to be as
follows
--
This invention has for its object the combination with a ball winding machine
of certain mechanism arranged in such manner that, the fibre can be wrapped
around the centre spindle or bobbin tight and compact without the use of weights
and weighted levers as hitherto in ordinary use, and in lieu thereof to so arrange
the additional parts, that the machine may be put in motion or stopped by the
operation of a lever and the pressure on the fibre applied or relieved as required,
without the attendant having to raise weights for relieving the pressure as is the
case with machines as ordinarily constructed: and also to so arrange and mount the
guide flanges that the balls may be removed therefrom without having to move
the flanges out of position.
We accomplish our object in the following manner-On a rotary shaft in
connection with the presser plate we place a brake pulley having a ratchet wheel
attached and free on the shaft so that it may move in a rotating direction and the
pulley and ratchet wheel remain stationary. On the said shaft is an arm or disc
carrying one or more pawls jointed thereto in such position as to engage with the
teeth of the ratchet wheel.
:
Around the circumference of the brake pulley is placed one or more straps the
ends of which are secured to some part of the machine, so that as the fibre is
wrapped around the centre spindle or bobbin on forming the ball, the pressure plate
is moved away from the centre, and its motion retarded by the before mentioned
pawls engaging with the teeth of the ratchet wheel and turning the brake pulley
within the strap or straps, thus causing the fibre to be wrapped tight and compact
on the ball which when of the required diameter, the machine may be stopped
automatically in the usual manner; or in place of the ratchet wheel and pawl
catch box may be mounted on the press plate shaft and made to engage with some
portion of the brake pulley, for turning the same within the brake strap as the
ball increases in diameter, a lever in connection with the clutch box being so
arranged that on the machine stopping, the clutch box is moved out of gear
with the brake pulley, thus leaving the press plate free so that it may be moved
with ease.
al
The guiding flanges are mounted on separate bearings, one flange to a rotating
shaft driven in a suitable manner, the other flange on a socket through which a
spindle may be placed having the end made to engage with the rotating flange
shaft. The fibre is wrapped around the spindle and when the ball is of the
diameter required, it is removed on withdrawing the spindle from the centre,
thus liberating the ball and when bobbins are used, we prefer to place a pin
through some portion of each bobbin and use a split spindle applied in a similar
manner so that the apparatus may be utilized with bobbins or without.

mprovements in Apparatus for Winding Balls of Fibre for Combing
Machines.
We, MICHAEL FIRTH, JOHN KNOWLES, and ISAAC HALSTEAD, of the firm of
M. Firth & Co. of Bolton Woods Shed, Frizinghall, Bradford, in the County of
York, Machine Wool Combers, and JOSEPH ROBERTSHAW of the same place
Combing Overlooker, do hereby declare the nature of this invention and in what
nanner the same is to be performed, to be particularly described and ascertained in. 5
and by the following statement :-
This invention has for its object the combination with a ball winding machine of
certain mechanism arranged in such a manner that, the fibre can be wrapped around
the centre spindle or bobbin tight and compact without the use of weights or
weighted levers as hitherto in use: and in lieu thereof to so arrange the additional 10
parts that, the machine may be put in motion or stopped by the operation of a
lever and the pressure on the fibre applied without the attendant having to raise
weights as is the case with machines as ordinarily constructed: and also to so
arrange and mount the guide flanges that the balls may be moved therefrom without
having to move the flanges out of position.
In the accompanying drawings
Fig. 1 represents a front elevation of a ball winding machine constructed
according to our invention.
Fig. 2. is an end view of the same.
Fig. 3. a back view.
Fig. 4. a detail of one of the levers and part of a ratchet wheel.
Fig. 5. a detail view of the opposite side of the last mentioned lever.
Fig. 6. a section through the end of a spring lever and
Fig. 7 a plan of one of the operating levers.
On the shaft A. is secured the arm of presser plate B. and to the said shaft is
mounted a brake pulley C having a ratchet wheel D attached thereto and free on
the shaft A. so that the latter may move in a rotary direction and the pulley and
ratchet wheel remain stationary.
On the said shaft is keyed an arm or lever E. carrying one or more pawls F. in
such position as to engage with the teeth of the ratchet wheel D. and on the back
of the lever E is a curved path E' with a recess cut therein for the purpose a
A lever G is mounted loose on shaft A and is provide
hereinafter described.
with a pawl H.
Around the circumference of the brake pulley C. is placed a strap C, the end
of which are secured to some portion of the machine frame in any manner by whic
the strap C may be adjusted to grip the circumference of the pulley, so that a
the fibre is wrapped around the centre spindle J. or a bobbin thercon it is cor
pressed thereon, the rotary motion being imparted to the centre spindle J by t
driving pullies P. through the spur gearing W.
The pressure plate B secured on shaft A is forced away from the spindle J. a
its motion is retarded by the before mentioned pawls F. engaging with the teeth
ratchet wheel D. by which the ratchet wheel, and thereby the brake pulley
turned within the tightened strap C, thus causing pressure to be put on
fibre so that, it is wrapped tight and compact on the spindle or bobbin, and w
the ball is of the required diameter, the machine is stopped automatically in
following manner.
On the centre spindle J secured to the boss of the flange plate K. is a tappe
which rotates and operates the lever G held in contact therewith by a spring,
causing the lever to reciprocate and the pawl H to slide on the curved path E
When the presser plate B. is forced back the distance c
back of lever E.
sponding to the desired diameter of the ball of fibre, the lever E will have m
'

page_text: an equal distance, when the reciprocating pawl H will drop into the recess R. so
that on the full portion of the tappet L. moving the lever G. in the direction of
the arrow, the lever E will be moved likewise in the same direction a distance
equal to the pick of the tappet, and by bar M displace the lever N. held by a
notch in a similar manner as the stopping spring of an ordinary machine.
When the lever N is released in the manner described, the spiral spring O will
contract, causing the belt rod Q to slide and move the driving belt from the fast
pulley P to the loose pulley P, thereby stopping the rotation of the centre spindle J
and the bail of fibre thereon.
On the driving belt being moved to the loose pulley P¹, the pulley P² secured
thereto will rotate also, and by the connection of lever S to arm N of lever N. the
belt fork T will move the belt running over pullies P2 and P from the loose to the
fast pulley of the latter, thus putting in motion the worm T and worm wheel T₁,
the latter being secured on shaft U. on the other end of which is secured a disc V.
which operates levers for withdrawing the centre spindle J from the ball of fibre
wrapped thereon, and forces the ball from between the flange plates K and K¹.
When the centre spindle J has been stopped in the manner described, the disc
pin 1. projecting from face of disc V. will be about the position shown at X. and
on the rotation of disc in the direction of arrow, the disc pin will press against the
underside of arın 2 of bell crank lever Y. thus causing the lever to move on its
fulcrum pin, and the upper portion connected by links to the centre spindle to
move away from the machine, and thereby withdraw the centre spindle J from the
ball of fibre. On the disc pin 1 arriving at the position shown, it will operate
lever 3 by pressing on the projection 4 at end of same, the lever operating on its
fulcrum pin, raises the sliding block 5 on stay bar 6. The block is attached to a
bar fitted with a plate 7 at the top, so that as the block 5 is raised, the plate 7
raises the ball of fibre between the flanges K and K'.
On the liberation of lever 3 by the disc pin clearing the projection 4. the
weight at the opposite end of the lever will cause it to resume its normal position
as shown in the drawings, and on its return will come in contact with the underside
of spring lever 8, thereby operating the same in the direction that the belt
fork T. moves the belt on to the loose pulley P1, thus stopping the rotation of
disc V.
The end of spring lever 8 is formed as shown by Fig. 6. in order to allow the
lever 3 to descend by sliding over the inclined surface, but on its return, the lever 3
will come in contact with the underside and thereby operate the belt fork T in the
manner described.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
1. In combination with a ball wrapping machine, of the presser plate B, brake
pulley C, ratchet wheel D, levers E and G all arranged substantially in the manner
shown and described.
2. In a ball wrapping machine the levers E and G in combination with the brake
pulley C and strap Cratchet wheel D tappet L and central spindle J all arranged
substantially in the manner as shown and described.
3. The tappet L in combination with the levers G and N, lever Y and central
spindle J, all arranged substantially in the manner as shown and described.
4. The tappet L in combination with the levers G and N disc V lever 3 and
plate 7 all arranged substantially in the manner as shown and described.
5. The lever 3 in combination with spring lever 8 and belt fork T all arranged
substantially in the manner as shown and described.
