We HENRY ERNEST LEETHAM, of Friars Terrace, Miller, and JAMES JONES of
Fishergate, Gentleman, both of the City and County of York do hereby declare the
nature of this invention to be as follows :-
The object of our invention is to dispense with the use of the ordinary flier and
spindle used on Throstle and other spinning machines for giving the twist and
winding onto the bobbin cotton, flax, silk, wool and jute threads and other fibrous
substances.
By our invention we dispense with the great amount of drag on the material
consequently there are fewer breakages, and the operation of winding and twisting
can be effected at a much greater speed than hitherto.
Instead of the ordinary spindle and flier now generally used we employ a tube as a
flier which may be of any required length, the base of which tube forms a support to
the revolving parts within; this tube is caused to revolve and is supported in fixed
rails top and bottom. This tube has a slot continued the whole or nearly the whole of
its length.
The bobbin may be a solid spindle with a fixed flange at each end, or formed of
thin tubing having a short spindle at each end, which project outwards to form the
supports for the bobbin. This bobbin rotates within the flier tube and is supported at
the top by its projecting spindle working in a removable bearing which is fitted into
the top of the flier tube.
The bottom spindle rests on the head of a drag spindle, and rotates therein. This
drag spindle rests upon the flange of a tube which runs through the bottom of flier
tube, and has at its lower end a small pulley fixed so that it may be readily put on or
taken off, and by this means the bobbin can be run faster or slower than the flier
tube as may be required. The drag spindle is carried forward below the pulley and
terminates with or without vanes as preferred, such vanes revolve with the drag
spindle in a metal tube of a little larger diameter than the vanes. This tube may be
supplied with liquid into which the vanes may be caused to dip to any extent so as
to more or less retard the movement of the vanes and thus increase or reduce the
drag on the bobbin, or when preferred the use of liquid may be dispensed with.

page_text: The thread is conducted down to the bobbin from the delivery rollers by means of a
conductor and guide, it then passes through the removable bearing which is provided
with a groove or slit leading to the inside of the flier tube, it is then carried forward
to a conductor attached to a sliding ring which is fitted so as to slide freely on the
exterior of flier tube and the thread is supported by a recess formed on the inside of
the tube.
This ring is caused to move up or down by a lifting rail and carries the thread
with it laying it on the bobbin in a regular and even manner whilst such bobbin is
revolving.
For imparting the required differential rotary motion to the flier tube and bobbin,
we employ an endless belt having projecting faces of india rubber or other suitable
material thereon.
This endless belt travels from end to end of the machine and so imparts motion to
all the spindles.
COMPLETE SPECIFICATION.
Improvements in Spinning Machinery.
We, HENRY ERNEST LEETHAM of Friars Terrace, Miller, and JAMES JONES of
Fishergate, Gentleman, both in the City and County of York, 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 :-
The object of our invention is to dispense with the use of the ordinary flier and
spindle used on Throstle and other spinning machines for giving the twist and
winding onto the bobbin cotton, flax, silk, wool and jute threads, and other fibrous
substances.
In our improvements we dispense with the great amount of drag on the material,
consequently there are fewer breakages and the operation of winding and twisting can
be effected at a much greater speed than hitherto.
Fig. 1 is a longitudinal section and Fig. 2 an elevation of general arrangement of
our apparatus which we use in place of the ordinary spindle and flier. Fig. 3 is an
elevation of the same with spiral slotted tube applied. Fig. 4 is a plan of top bearing
of spindle, and Fig. 5 is a modification of retarding apparatus.
Instead of the ordinary spindle and flier now generally used we employ the

page_text: tube A as a flier, which may be of any required length. This flier tube A is
caused to revolve and is supported in fixed rails B and B¹, the rail B being near the
top of the tube A, and the rail B¹ near the bottom thereof. The small part C passes
through the bottom rail B', or only partially through. The tube A has a straight or
spiral slot D continued the whole or nearly the whole length of its larger diameter.
The base of the larger diameter of the flier tube A supports the whole of the revolving
parts within.
-
The bobbin E may be a solid spindle with or without a fixed flange at each end,
or formed of thin tubing having short spindles F and F¹ with fixed flanges G and G¹.
These are inserted in the tube as shewn. The outer ends of the solid spindles F and F¹
project outwards to form the supports for the bobbin E.
The bobbin E rotates with the tube A and is supported at the top by its projecting
spindle F working in bearing H which bearing is removable to take out the full
bobbin, and is fitted into the top of flier tube, and conducts the thread through slots I
in the projections of the bearings.
The bottom spindle F' rests on the head of a drag spindle J, (to be described
hereafter) and rotates therein. such head forming a bearing for the same.
The top of the drag spindle J is made of sufficient depth to form a suitable length
of bearing for the solid spindle F¹.
The boss or flange K of the drag spindle J rests upon the flange L of a tube M,
which runs through the bottom or small end of the flier tube A and has at the lower
end thereof a small pulley N fixed by any suitable means, so that it may be readily
put on or taken off, and by this means the bobbin E can be run faster or slower
than the tube A as may be required. The tube M with pulley N may be
dispensed with when it is not necessary for the bobbin to exceed the speed of
the flier.
The drag spindle J is carried forward below the small pulley N and terminates
with or without the vanes O as shewn at Fig. 1, or fliers P as shewn at Fig. 5, as
preferred.
These vanes O or fliers P revolve with the drag spindle J in a tube R of metal or
other material of a little larger diameter than such vanes O, or fliers P.
This tube R may be supplied with liquid into which the vanes O or fliers P may be
caused to dip to any extent, so as to more or less retard the movement of the vanes or
fliers, and thus increase or reduce the drag on the bobbin E, or when preferred liquid
may be dispensed with, thus exposing the vanes or fliers to the action of the air.
This tube R may be adjusted up or down in its bearing S.
The retarding arrangement when not required may be dispensed with.
Fig. 3 shews the flier tube A with straight slot D covered by another tube T with a
spiral slot U, such tube being fitted theron so as to slide freely over the inside tube A
as the ring V is moved up or down, opening a way for the thread to be passed to the
bobbin, at the same time supporting the thread from centrifugal force, and the
straight slot D of the inside tube forms a recess for the thread, so that it may be clear
from any part of the bobbin when revolving, or the outside slotted tube may be
dispensed with.
The thread W is conducted down to the bobbin E from the delivery_rollers by
means of a conductor and guide, it then passes down through the bearing H which is
provided with the grooves or slots I, it is then carried forward to conductor X
attached to the sliding ring V, fitted so as to slide freely on the exterior of flier
tube A.
The ring V rotates with the flier tube A and at the same speed and is caused to
move up or down by the lifting rail Y and carries the thread W with it, laying it on
the bobbin E in a regular and even manner, whilst such bobbin is revolving.
We do not confine ourselves to any particular means of raising and lowering the
ring V, as any convenient means may be employed.
For imparting the required differential rotary motion to the tube A and bobbin E
we employ an endless belt 1, having the projecting faces 2 and 3 of india rubber or
other suitable material. These projecting pieces 2 and 3 vary in thickness to suit

page_text: the diameter of the parts to which they are to give motion. The endless belt 1
travels from end to end of the machine, and so imparts motion to all the spindles
simultaneously.
The ordinary system may be employed for imparting motion to the spindles instead
of the above arrangements.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we
claim is :-
--
1st. The arrangement, construction and application of flier tube A, substantially as
and for the purposes herein set forth.
2nd. The arrangement and application of small tube M constructed as described
having at its lower end removeable small pulley N, substantially as and for purposes
