I, JAMES WHITEHEAD, of Ashton-under-Lyne, in the County of
Lancaster, do hereby declare the nature of the said Invention for "Im-
PROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING COTTON AND OTHER
TEXTILE MATERIALS," to be as follows:-
My Invention relates principally to machinery for doubling yarn, but
a portion of the said Invention may also be applied in the process of
spinning as will be herein-after indicated. In doubling machines as
hitherto constructed the ends of yarn have been twisted and wound upon
bobbins by means of flyers.
My Invention consists in the first place in winding the yarn off the
bobbins which are mounted on the spindles which twist the yarn. The
rising and falling rail is dispensed with, and the yarn may be wound
directly upon large bobbins in the doubling machine, and also longer
bobbins may be placed upon the spindles and shorter flyers may be used.
As the spindle bobbins do not revolve or drag upon a rail as in the

page_text: ordinary doubling machines there is less friction, and consequently less
driving power is required.
In an arrangement for effecting this part of my Invention the bobbin
rests upon a disc or collar fixed to the spindle, and the said collar is fitted
with fingers or arms like an inverted flyer. The yarn is unwound from 5
the bobbin and after receiving twist is wound upon a taking up bobbin.
or spindle which may be driven by frictional contact acting on the yarn
on the said taking up bobbin or spindle or by other suitable means.
In another arrangement the flyer is dispensed with and a spool bobbin
without an upper end or flanch holds the yarn and rests upon a collar on 1
the spindle. The yarn passes from the said spool bobbin through or
over a fixed guide or rest to the taking-up bobbin, the yarn when
passing from the said guide or rest to the said taking-up bobbin making
such an angle with the axial line of the spindle as will enable the yarn
to be drawn off the said spool bobbin with a suitable amount of tension 1
during the revolution of the said spindle.
In a second part of my Invention I impart two twists to the yarn
during a single revolution of the spindle and flyer. To effect this I
employ a double ended horizontal flyer, one end of the said flyer carrying
a spindle on which is mounted a tube which receives the bobbin. An 2
arm is attached to or formed on the said tube and an cyo is formed in
one end of the said arm. Tho said arm hangs down and prevents the
bobbin from revolving. The yarn is led from the bobbin through the
said cye and through one end of the flyer, and is thon led up one leg of
the flyer to the other end thereof, from whence it is led through the 2
journal of the flyer to the taking up bobbin or spindle.
In a modification of this arrangement a frame to hold two or more
cops is mounted upon the tube in place of a bobbin, the skewers which
hold the cops being hinged to the frame for convenience of doffing.
The arrangement may also be adapted to spinning by causing the yarn 3
to bo wound upon the bobbin instead of being unwound therefrom. In
such a case it would be necessary to provide means for traversing the
guide eye to and fro, which may be effected by means of a screw cut
with a right and left hand thread and driven by means of worm gearing,
the whole arrangement being contained within the flyer.

off from the bobbins and be wound upon an additional set of bobbins or
spindles without removal of the full bobbins from the flyers, and may
receive a further amount of twist during the winding of the yarn upon
the said additional bobbins or spindles.
