SPECIFICATION.
I, JOHN SCOTT of No 6 Vestry Street Wakefield Road, Bradford, Yorkshire
Commission Wool Comber, do hereby declare the nature of my invention for
IMPROVEMENTS IN APPARATUS FOR WINDING OR PREPARING SLIVERS FOR
COMBING MACHINES" to be as follows:-
This Invention relates to apparatus for winding the wool upon a cylindrical core
so as to form the same into a ball or bobbin ready for feeding the combing
machine. According to my Invention the wool after passing through a gill box is
wound in one or more slivers upon a cylinder having a flange at each end secured
thereto by means of a central spindle and lock nuts, thus formning a solid bobbin.
The central core rests upon a friction roller of large diameter and slightly
shorter in length than the distance between the bobbin flanges so as to avoid any
frictional contact therewith. The wool after leaving the gill combs or feed rollers
passes over and around the central core of the bobbin, and the necessary tension is
imparted by means of a presser bar and weighted lever.
As the bobbin fills it rises in slotted guides, and when full the bell crank lever
to which the presser bar is attached knocks off the strap guide.
The lock nuts which secure the ends or flanges of the bobbin are then removed,
the spindle withdrawn and the central core and wool wound thereon are taken
away, and another core substituted.
By my Invention the fibres on the extreme edges of the bobbin are not subjected
to any rubbing or friction as is the case in machines in which the ball is formed
between stationary end plates or flanges.
In order to wind the slivers firmly upon the bobbin I attach a vertical rod to
the axle of the said bobbin, which rod is connected to a weighted horizontal lever
in such manner that the weight thereof on the axle winds the sliver hard and firm
upon the bobbin.

I JOHN SCOTT of 6 Vestry Street, Wakefield Road, Bradford, Yorkshire,
Commission Wool Comber, do hereby declare the nature of my invention for
IMPROVEMENTS IN APPARATUS FOR WINDING OR PREPARING SLIVERS FOR
COMBING MACHINES and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
"
This Invention relates to apparatus for winding slivers of wool onto cylindrical
cores so as to form the same into balls ready for feeding the combing machine.
According to my Invention, the wool, after passing through a gill box, is wound
in one or more slivers upon a cylindrical core having a flange at each end
temporarily secured thereto, and forming in combination therewith a flanged
bobbin. The central core rests upon a friction roller of large diameter, and slightly
shorter in length than the distance between the bobbin flanges, so as to avoid any
frictional contact therewith.
In sheet 1 of the accompanying drawings, Fig. 1 is a side elevation of a balling
machine with my improvements applied thereto; and Fig 2 is a plan view of
the same, certain of the parts common to balling machines being omitted as
unnecessary.
In these Figures the bobbin is represented as empty.
Fig 3 Sheet II shows the opposite side of the balling machine to that repre-
sented at Fig 1, the bobbin in this case being full, and the ball ready for
removal,
Fig is a longitudinal section of the bobbin, which consists of a cylinder a, to
the opposite ends of which are fitted discs a¹ having hubs a² in which annular
grooves are turned for the purpose to be presently explained.-The several parts
constituting the bobbin are threaded upon an axle A, which is formed with a
shoulder against which the hub of one of the discs bears, while a fly nut on the
screwed end of the axle is caused to bear on the hub of the other disc, and thus
bind all the parts of the bobbin together.
By this arrangement, I form a flanged bobbin, the cylindrical portion of which
is readily detachable from its flanges, and will serve as a core for the bull of aliver.
The axle of this flanged bobbin is mounted in vertical guides in the framing B,
and immediately above a friction roller C, which is of such length as to allow
of the cylinder a of the bobbin resting upon it, without its flange a' being in
contact with the friction roller.-The slivers to be balled are led from a gill box or
a creel or can, whichever is preferred, between the feeding rollers D and E to the
bobbin, and after passing under the bobbin, they are laid around it. The drawing
represents four trumpet mouths for feeding a corresponding number of slivers to
the bobbin, but the number of slivers received onto one bobbin will vary according
to the requirements of the manufacturer.
The friction roller C, and also the feed rollers, are driven by gearing in the usual
manner.
To ensure the bobbin turning by friction of contact with the roller C, it is held
down thereon by hooked rods FF jointed to a pair of weighted arms of a rocking
shaft having its bearings at the lower part of the framing B. A central arm F
projecting from this rocking shaft carries a tread for the foot of the attendant, the
depression of which serves to release the bobbin from the weight of the rods F.
The hooks of these rods enter the annular grooves in the bosses of the bobbin,
which grooves also serve to embrace the guides which hold the bobbin in place in
the machine.

page_text: As the bobbin rotates under friction of contact with the roller C, it will wind on
the slivers fed to the Machine, and by reason of its increasing diameter, it will
rise up the guides to the position of Fig 3.-In order, however, to ensure a firm
balling of the sliver, a presser bar G is employed, as heretofore, carried by arms
from a weighted rock shaft G¹ having its bearings in the main framing and carrying
a arm G²
When the bobbin has risen to the position of Fig 3, the feeding of the sliver
will be stopped automatically in any well known manner.
At this time the attendant, by depressing the arm F², will lift the hooked rods F
clear of the bobbin, leaving them to fall to the back position shewn at Fig 3; at
the same time he will depress the arm G, and thereby cause the presser bar G to
push forward the filled bobbin to the dotted position of Fig 3,-the upper edges of
the fraining adjacent to the vertical guides being suitably formed to receive and
retain the bobbin, the annular grooves of the bosses of the discs or flanges
embracing the part of the framing on which the bobbin rests.
It now only remains for the attendant to remove the fly nut from the axle A, and
to withdraw the axle from the bobbin.
The central core, carrying the balled sliver, will then drop, and be caught by the
receiving plate H, as shown at Fig 1, while the discs or flanges al of the bobbin
will be retained in position on the framing-The detached "ball" is then to be
removed, and the central core, after being withdrawn from the ball of sliver, is to
be applied to the flanges for the purpose of reforming the bobbin as before.
This empty bobbin with its axle, when inserted in place as at Fig 1, will be
ready, at the restarting of the machine, to take up the sliver fed to the friction
roller C, the hooked rods F F having been replaced on the hubs of the bobbin.―
I would remark that by the use of my Invention the fibres which lie at the ends
of the "ball" or roll of sliver, are not subjected to undue rubbing or friction, as is
the case when the ball is, as usual, formed between stationary end plates or flanges.
I have said that the filled bobbin is released from the pendent hooked rods F by
the attendant; it will, however, be obvious that this result may be obtained
automatically if thought desirable.
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. Constructing bobbins for receiving slivers, of detachable parts, in the manner
and for the purpose above described.
2. The use, in winding or preparing machines, of bobbins constructed as above
described, such machines being fitted to retain the bobbin flanges in position for
receiving the core or cylinder on which the ball of sliver is to be formed.
3. The arrangement of detachable pendent apparatus above described for holding
the bobbin in contact with its supporting friction roller.
