PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Spinning Yarn.
I, ARTHUR GREEVES, of Fourth River Mill, Falls Road, Belfast, in the
County of Antrim, Ireland, Mill Manager, do hereby declare the nature of this
invention to be as follows:-
In the spinning of yarn from flax, cotton and other fibres it has hitherto been
customary to wind the yarn as it is spun, upon the external surface of a bobbin,
spool, pirn, or paper tube placed upon a rotating spindle.
This invention consists essentially in winding the yarn as it is spun upon the
internal surface of a rotating cylinder or cup and providing a suitable guide eye or
its equivalent to guide the yarn to the interior of the cylinder.
In carrying out the invention I dispense with the ordinary bobbin or pirn and
Hyer and construct the spindle with a cylindrical or other cup upon the internal
surface of which the yarn is wound or wrapped. To the builder rail or other
traverse motion I attach a pillar or rod with an eye at the end to guide the
yarn. This pillar is bent or shaped so that the end carrying the eye may pass
down into the interior of the cup.
The yarn is passed through the eye to the centre of the cup and when the
end is laid against the side of the cup while rotating the centrifugal force holds
it there and draws down the yarn from the rollers as it is given off and lays it
against the inner surface of the cup.
The inside of the cup may if desired be lined with a wooden, paper or other
lining to serve as a carrier or vehicle for the yarn instead of the bobbins or
pirns at present in use or if found more convenient the yarn may be wound on
the bare cup and removed therefrom in the form of a roll.
The yarn guide or eye may be caused to rotate if desired.
By this invention I consider I obviate the strain on the yarn such as at present
caused by its being rotated by the flyer eye or ring traveller and I anticipate that
in consequence of this and the reduction of vibration and the doing away with
the drag either by traveller or drag string I shall be able to run the spindles
at very high speeds.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Spinning Yarn.
I, ARTHUR GREEVES, of Forth River Mill, Falls Road, Belfast, in the County
of Antrim, Ireland, Mill 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 :-
In the spinning of yarn from flax, cotton, and other fibres it has hitherto
been customary to wind the yarn as it is spun, upon the external surface of a
bobbin, spool, pirn, or paper tube placed upon a rotating spindle.
This invention consists essentially, in winding the yarn as it is spun upon the
[Price 8d.l

page_text: internal surface of a rotating cylinder or cup; in the combination with a spindle
of a cup or hollow cylinder to receive the yarn, and in a suitable guide or its
equivalent to guide the yarn to the interior of the cylinder.
It will be fully described with reference to the accompanying drawings in which
one spindle is shown to illustrate the invention.
Fig. 1. Sectional elevation.
Fig. 2. Plan.
In carrying out the invention I dispense with the ordinary bobbin or pirn upon
which the yarn is wound during spinning and also with the flyer which winds or lays
and guides the yarn onto the pirn or bobbin during the process.
I construct the spindle A with a cylindrical or other cup B attached to its upper
end the cylinder or cup being secured by any suitable means and open at the top.
To the builder rail C or to other traverse rail or mechanism I attach a pillar
or rod D carrying on an adjustable wire d a guide E with an eye e to guide
or direct the yarn F into the interior of the cup or cylinder B upon the internal
surface of which it is wound. The guide E is preferably partly cylindrical to
prevent the end flying about or catching should an end break.
The yarn F passes from the rollers G in the usual way and is then passed through
the eyee of the guide E to the axial or longitudinal centre of the cylindrical
cup B.
The spindle A and cup B are caused to rotate at a very high speed and
the end of the yaru is laid against the side of the cup whilst it is rotating; the
centrifugal force acting on the thread, now in contact with the cup, and carried
round thereby, draws down the yarn as it is delivered from the rollers and lays it
against the inner surface of the cup one layer upon the top of another.
The inside of the cup B is preferably lined with a wooden, paper, or other
lining to serve as a carrier or vehicle for the yarn instead of the bobbins or pirns
at present in use or if found more convenient the yarn may be wound on the bare
cup and removed therefrom in the form of a roll.
The yarn guide may be caused to rotate if found desirable to assist in the
winding on of the yarn in which case it will be attached to a rotating spindle
either supported above the cup or concentric with the spindle A. For flax or
other yarns which are spun wet the cylinder may be perforated to allow of the
water draining off.
By this invention I do away with the strain on the yarn in its passage from
the nip of the rollers to the bobbin caused by the centrifugal force due to its
rotation in a circular path by the flyer eye in flyer spinning, or ring traveller
in ring spinning. I also prevent irregular tension caused by the drag in flyer
spinning or the traveller in ring spinning, which devices are necessary to act
against the centrifugal tendency and wind the yarn on the bobbin.
In my
method it will be seen that the yarn descends along the axis of rotation to the
plane at which it is to be wound in the cup, and the centrifugal force acts directly
only on so much of the yarn as reaches from the central eye e to the side of the
cylinder or cup; and I make use of that centrifugal tendency to wind the yarn in
the cup and draw it down from the rollers. By these means I can spin yarn,
especially delicate yarn, at a much higher speed than has hitherto been possible.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. In the process of spinning yarn the winding of it by centrifugal force
upon the interior surface of a rapidly rotating cup or cylinder substantially as
described.
2. A spindle for spinning yarn constructed with a cup or hollow cylinder to
receive the yarn mounted upon the top of the spindle in combination with a guide
to deliver the yarn into the interior of the cup substantially as described.
3. In a spinning frame the combination of the spindle A the hollow cup or

page_text: cylinder B into which the yarn is wound and the guide E placed in the centre of
the cup substantially as described.
