IMPROVEMENTS IN SPOOL OR PIRN WINDING MACHINES
Year: 1885

page_text: We, JOE BOOTH WHITELEY, and WILLIAM WHITELEY, of the firm of William
Whiteley and Sons, Lockwood, near Huddersfield, Yorkshire, Machine Makers do
hereby declare the nature of our invention for "IMPROVEMENTS IN SPOOL OR PIRN
WINDING MACHINES," to be as follows:-
This Invention has reference to that class of pirn or spool winding machine
where the yarn is wound upon the bobbin by frictional contact with three cones,
the said cones working loosely upon centres and arranged that the apex of the
cones are pointing upwards.
The object of our Invention is to provide a new method or means for guiding
the yarn to the spool. Hitherto this has been done by a rod running the whole
length of the machine, but as the bobbin was rotating within the space formed by
the three cones, the said guide rod could not get sufficiently near the bobbin,
consequently the distance between the guide rod and bobbin was too great for the
proper winding of the yarn.
Our Invention consists in fastening onto the usual guide rod a suitably shaped
finger, formed with a ^ or other suitable point so as to enter into the angle formed
by two cones; by this means the yarn can be guided close up to the bobbin,
whereby a solid and firm spool can be wound.

We, JOE BOOTH WHITELEY and WILLIAM WHITELEY of the firm of William
Whiteley and Sons, Lockwood, near Huddersfield, Yorkshire, Machine Makers do
hereby declare the nature of our invention for "IMPROVEMENTS IN SPOOL OR PIRN
WINDING MACHINERY" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention has reference to that class of pirn or spool winding machine
where the yarn is wound upon the bobbin by frictional contact with three cones,
the said cones working loosely upon centres and arranged that the apex of the
cones are pointing downwards.
The object of our invention is to provide a new method or means for guiding
the yarn to the spool.
Hitherto this has been done by a rod running the whole length of the machine,
but as the bobbin was rotating within the space formed by the three cones, the
said guide rod could not get sufficiently near the bobbin, consequently the distance
between the guide rod and bobbin was too great for the proper winding of the
yarn.
Our invention consists in fastening onto the usual guide rod a suitably shaped
finger formed with a A or other suitable point so as to enter into the angle
formed by two cones.
Such being the nature and object of our Invention we will now proceed to
describe the same more fully and for that purpose have annexed the accompanying
sheet of drawings wherein Fig. 1 is plan view of one set of cones having our
improvements applied thereto, and Fig. 2 is section of same taken through the
line A, B, in Fig. 1.
C are three ordinary cones provided with spindles D running loosely upon their
centres a in fixings E and F.
The spool upon which the yarn is wound is shewn at G, the conical part of
which is of the same angle as the cones, so that when the spool is empty and
placed into the space formed by the three cones, the conical part of the spool
would be touching each cone.
H is the ordinary guide rod running full length of the machine and the yarn to
be wound upon the spool has hitherto been guided thereto by the said rod H. This
rod H is carried by an arm I fixed to the rocking shaft J, which gives to the guide
rod an oscillatory motion equal in stroke to the length of the cones, all of which
are well understood and in common use.
On examination of the drawings it will be apparent that the guide rod could not
be brought nearer to the spool than the drawings illustrate and in practice we
have found that if the yarn could be supported close up to the spool that a more
solid and firm cop could be wound. To do this we fix onto the guide rod opposite
the centre of each spool a finger or plate K formed with a tapering point as at b
so as to get between the cones and close up to the spool as the drawings illustrate,
by which means the yarn is supported close up to the spool and as yarn is wound

page_text: thereon the point b of the plates K is always in close proximity to the last layer
of yarn wound upon the said spool whereby the desired effect is obtained.
In Fig. 2 the plate K is shewn in its highest position, and the dotted lines shew
its lowest position.
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
we claim is
The finger or plate K so shaped and formed as to get close up to the spool G in
cone winding machines in manner and for purposes set forth.
