Improvements in Bobbins, Spools, or Pirns for Receiving or Holding
Yarn, Thread, Cord or the like during Manufacture or otherwise.
We, RICHARD HAYNES, of Park Road, Hockley, Birmingham, in the County of
Warwick Rope and Twine Maker and JOHN WILCOCK, of Cecil Street, Greenheys,
Manchester, in the County of Lancaster, Manager do hereby declare the nature of
this invention to be as follows:-
The invention relates to the bobbins, spools, or pirns upon which yarn or other
material is wound in the ordinary course of spinning or doubling or upon which
thread, cord or other material may be placed to be held or carried when being
tinwound and it is designed with the object of providing a bobbin spool or pirn
which can be easily withdrawn from or inserted in a full cop ball or roll of the
material.
It consists essentially of a bobbin spool or pirn, split or divided at or near the
centre of the tube so that the tube can be readily withdrawn from or inserted in the
cop ball or roll of material.
In carrying out the invention the bobbin spool or pirn is constructed as usual
Where flanges are used
with a central tube with or without flanges at the end.
they may be attached to the tube in any ordinary way. The tube we divide
transversely at or near the centre and preferably make it tapering from the centre
in both directions forming two truncated cones with the apex of each at the centre.
The tubes may be of any length and of any diameter both internally and exterually
to suit the material to which it is to be applied or when intended as a holder only
and not to fit on to a spindle may be made solid instead of being hollow or bored
out. The two parts of the central tube or cylinder are jointed together by one end
being slipped inside the other or otherwise and are secured by a screw, bayonet
joint, spring or other method which will cause the two to turn together when used
for winding the material upon. When thus jointed together the parts take the
form of the ordinary bobbin spool or pirn and may be used for any purpose to which
such are applied where it is desired or will be of advantage to remove it from the
cop ball or roll.
Instead of making the barrel of the bobbin spool or pirn of two truncated cones
jointed together at the middle we may make it of two tubes an inner and an outer
one. The inner one we make parallel and the outer one in the form of a truncated
cone. The parallel tube is inserted in the conical tube and attached thereto by any
of the means such as before described.

-warehouses upon shop counters or other places it is made in two pieces as described

made hollow and a spindle passed through it or made solid with bearings on the
ends outside the flanges. The frame to hold or support it may be of any convenient
or suitable form to allow it to rotate vertically or horizontally as the string is
drawn off from the outside of the ball. By the use of this invention for the purpose
of holding balls of twine cotton or the like they may be unwound from the outside
instead of from the inside without becoming entangled at the end.

COMPLETE SPECIFICATION.
Improvements in Bobbins, Spools, or Pirns for Receiving or Holding
Yarn, Thread, Cord or the like during Manufacture or otherwise.
We, RICHARD HAYNES, of Park Road, Hockley, Birmingham, in the County of
Warwick, Rope und Twine Maker, and JoHN WILCOCK, of Cecil Street,
Greenheys, Manchester, in the County of Lancaster, Manager, 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 relates to the bobbins, or spools upon which yarn or other
material is wound in the ordinary course of spinning or doubling or upon which
thread, cord or other material may be placed to be held or carried when being
unwound and it is designed with the object of providing a bobbin or spool which
can be easily withdrawn from or inserted in a full roll or ball of the material..
It consists essentially of a bobbin, or spool, split or divided preferably at or near
the centre of the barrel or tube so that the barrel or tube can be readily withdrawn
from or inserted in the roll or ball of material.
The invention will be fully described with reference to the accompanying
drawings.

The bobbin or spool A, is constructed with a central barrel or tube a with a
flange Bon each end. The flanges B are of any suitable construction and are
attached to the ends of the barrel or tube a by any ordinary means, or formed
integral therewith.
The barrel or tube a of the bobbin is at or near its centre divided transversely so
as to form a bobbin in two parts, one part carrying one flange and the other part-
the other flange.
The bobbin A may be of any size or any diameter and the barrel or tube a may
be of any required length or diameter to suit the purpose or material to which it is
.to be applied.
way.
The two parts of the barrel or tube a are firmly secured together in any convenient
In Fig. 2, a screw joint is shown one end being screwed into the other, while
in Fig. 7, a telescopic joint is shown one or both ends of the divided barrel being
fitted with a thin metal tube or ferrule a one fitting into the other. In this form

page_text: the two may be held together by the friction of the joint or a bayonet joint may be
formed thereon to hold them secure. When thus jointed together the parts take
the form of an ordinary bobbin or spool.
The divided bobbin thus formed may be used for any of the purposes to which
the ordinary bobbin is applicable for winding or the like, and has the advantage
that the roll or ball of material can be removed therefrom and placed upon another
bobbin without being unwound and re-wound and the divided bobbin may also be
used as a holder for rolls or balls of twine or yarn whilst being unwound.
When intended for holding twine each end of the divided bobbin is made tapering
from the centre to the flange in the form of a truncated cone with the apex at the
centre, as shown in Fig. 9, and this instead of being hollow to receive a movable
spindle may have a pivot fixed in each end. The spindle or pivots are mounted in
a suitable frame E.
When used for spinning or winding upon, we place upon the bobbin barrel
between the flanges a tube B' of paper or cardboard or similar material upon which
the roll C of yarn is wound, which when removed from the bobbin keeps the centre
of the roll C from being disarranged. In this form the roll C of yaru roving twine
or the like as shown in Fig. 7, may be transferred from place to place without
conveying the bobbins or unwinding and handling the yarn. For fine yarns we
prefer to use flanges or discs D to cover and protect the ends. These may either
be flat cardboard dises or discs provided with a short core of which fits into the end
of the roll D or the paper tube B upon which the roll C is wound. The discs or
flanges D are secured in position in the ends of the roll by the spindle or skewer D'
or by a cord or string passed from one to the other. When a cord or string is used
it is passed into the eyelets d' either through the inside or round the outside of the
roll C.
When yarns are spun direct on to the ordinary bobbin it is customary to reel
them off the bobbins into hank form so that they may be portable for the market
in which the spinner sells to the manufacturer or consumer.
There is an expense
incurred in this reeling or unwinding of the bobbin. In most cases before the said
yarn can be used in the machines of the manufacturer it has to be re-wound from
the hank form back on to bobbins and thus the expense named is double. Our
invention obviates both the first and second winding in the manner following:-
When the spinning, twisting, or other frame is working with our divided bobbins
and after the said bobbins have been filled with yarn or twine or cord or wire or
the like, the two parts of the bobbin as above described can be withdrawn from the
ends and the yarn thus wound will bear handling after the manner of an ordinary
cop of cotton yarn and may in this form or with the addition of the flanges D be
transferred from spinner to manufacturer or consumer.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. A bobbin or spool upon which yarn, twine, thread, or the like, is wound or
held, divided transversely in two parts, at or near the centre of the barrel, so that
the material can be removed therefrom or placed thereon in the form of a roll or
ball without unwinding and rewinding, substantially as described.
2. A divided bobbin for holding balls of twine, thread, or the like, formed with
truncated cone shaped ends having the apex of each at or near the centre,
substantially as described.
