I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in
the County of Lancaster, and 323, High Holborn in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
The invention relates to apparatus for spinning, twisting, or doubling fibrous
substances etcetera, and relates particularly to the construction and arrangement of the
flyer spindle and spool. The spool which can easily be taken off, is firmly connected
with the spindle rotated by a small pulley. The flyer is constructed independent of
the spool, and terminates in a tubular spindle, which rotates in fixed bearings. The
fibrous substance passes through this tubular spindle over one arm of the flyer, and
passing downwards is led round the half of the periphery of a ring connecting the
ends of the flyer arms, and thence runs to the spool. The flyer is not actuated in the
usual manner, but is rotated by the traction exerted by the yarn or thread which is
being wound off. The speed of rotation can be regulated by means of a brake, acting
on the aforesaid tubular spindle, which revolves in bearings. The number of revo-
lutions required for a given length of thread can accordingly be determined. By this
invention a stronger construction of the spindle and an easier access to the latter are
secured. As it is no longer necessary to unscrew or remove the flyers from the
spindle, a great saving of time is effected. The invention is applicable to all sorts of
spindles and flyers of any size.
Three of the most important ways of carrying out the invention will now be
described.

page_text: The spindle is rotated in fixed bearings by means of a pulley or wharve. At a little
distance from its upper end, it carries a plate provided with a binding device to which
the lower head of the spool (which is tightly engaged on the spindle) is securely
engaged. Other arrangements can also be used which can be easily disconnected,
and form at the same time a secure connection between the spool and the spindle. In
this arrangement the flyer is independent of the spool and spindle. The flyer is
provided at its upper end with a vertical tubular spindle revolving in bearings
attached to a carrier capable of moving vertically. A spring braking device is applied
between the two bearings, in which the aforesaid tubular spindle rotates. The
brake blocks or segments can be brought to bear more or less against the tubular
spindle by means of a thumb nut which admits of the strap to which the said blocks
are attached being brought nearer together, or further apart. A nut or its equivalent
applied to the end of the tubular spindle, prevents it from shifting vertically in its
bearings.
In a modification of the foregoing arrangement the nut which prevents the tube
from shifting in a vertical direction, serves also as a friction disc, on the friction
surface of which the brake blocks are brought to bear. In this case there is only one
long vertical bearing to guide the tube.
In another modification, the vertical tube forms a conical bearing which is engaged
over a wooden hollow pin and secured therein by means of a nut applied to the lower
end of the latter. The arrangement of the braking device is the same as in the first
arrangement described. In the present modification, the yarn comes in contact with
the revolving parts when it has issued from the hollow pin. The path followed by
the yarn is the same in the three arrangements. The material is led through the tube
over one of the combs at the upper end of the flyer, and thence following a downward
path along the arm of the flyer, it passes over a projection at its end, and enters in
the groove of the ring which connects both arms of the flyer. The thread occupies
only one half of the periphery of this groove, whence it passes over the projection of
the opposite arm of the flyer to the spindle, and finally on to the spool.

of Bavaria, Empire of Germany, Engineer, (through Wirth & Co.)
I, WILLIAM PHILLIPS THOMPSON F.C.S. M.L.M.E. of the Agency for Foreign
Patent Solicitors 6, Lord Street, Liverpool and 6, Bank Street Manchester, both in
the County of Lancaster & 323 High Holborn in the County of Middlesex Civil
Engineer 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 invention relates to apparatus for spinning, twisting, or doubling fibrous
substances etcetera, and relates particularly to the construction and arrangement of
the flyer spindle and spool. The spool which can easily be taken off is firmly
connected with the spindle rotated by a small pulley. The flyer is constructed
independently of the spool, and terminates in a tubular spindle, which rotates in
fixed bearings. The fibrous substance passes through this tubular spindle over one
arm of the Hyer, and passing downwards is led round the half of the periphery of
a ring connecting the ends of the flyer arms, and thence runs to the spool. The
flyer is not actuated in the usual manner, but is rotated by the traction exerted
by the yarn or thread which is being wound off. The speed of rotation can be
regulated by means of a brake, acting on the aforesaid tubular spindle, which
revolves in hearings. The number of revolutions required for a given length of
thread can accordingly be determined. By this invention a stronger construction
of the spindle and an easier access to the latter are secured. As it is no longer
necessary to unscrew or remove the flyers from the spindle a great saving of time
is effected. The invention is applicable to all sorts of spindles and flyers of any
size.
Three of the most important ways of carrying out the invention will now be
described.
In the accompanying drawings.

with this invention.
Figure 2 is a side elevation at right angles to Figure 1.
Figure 3 is a plan.
Figures 4 and 5 show in vertical section and plan respectively a modification of the
apparatus.
Figures 6 and 7 are similar views of another modified form.

page_text: Referring now to Figures 1, 2 and 3.
The spindle A is rotated in fixed bearings by means of a pulley or wharve A¹. At
a little distance from its upper end, it carries a plate B provided with a binding device
to which the lower head of the spool C (which is tightly engaged on the spindle) is
securely engaged. This binding device may consist of a number of spring clips round
the plate B. Other arrangements can also be used which can be easily disconnected,
and form at the same time a secure connection between the spool and the spindle. In
this arrangement the flyer a is independent of the spool and spindle. The flyer a is
provided at its upper end with a vertical tubular spindle 6 revolving in bearings c
attached to a carrier capable of moving vertically. A spring braking device dis
applied between the two bearings C, in which the aforesaid tubular spindle b.rotates.
The brake blocks or segments can be brought to bear more or less against the tubular
spindle 6 by means of a thumb nut which admits of the strap to which the said blocks
are attached being brought nearer together, or further apart. A nut or its equivalent
applied to the end of the tubular spindle 6, prevents it from shifting vertically in its
bearings c.
In a modification of the foregoing arrangement shown in Figures 4 and 5, the nut d,
which prevents the tube b from shifting in a vertical direction, serves also as a friction
disc, on the friction surface of which the brake blocks are brought to bear. In this
case there is only one long vertical bearing c to guide the tube.
In another modification shown in Figures 6 and 7, the vertical tube 6 forms a
conical bearing which is engaged over a wooden hollow pin e, and secured thereon by
means of a nut applied to the lower end of the latter. The arrangement of tlie.
braking device is the same as in the first arrangement described. In the present
modification, the yarn comes in contact with the revolving parts when it has issued
from the hollow pin. The path followed by the yarn is the same in the three
arrangements. The material is led through the tube over one of the combs at the
upper end of the flyer a, and thence following a downward path along the arm of the
flyer, it passes over a projection at its end, and enters in the groove of the ring which
connects both arms of the flyer. The thread occupies only one half of the periphery
of this groove, whence it passes over the projection of the opposite arm of the flyer a
to the spindle, and finally on to the spool C.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is
1. In apparatus for spinning, twisting, or winding, a flyer which is independent of
the spool carrying spindle, and is provided at its upper part with a vertical tubular
spindle which forms a revolving support for the said flyer, substantially as and for the
purposes set forth.
2. The various improvements in apparatus for spinning, twisting, or winding, sub-
stantially as described.
