Complete Specification Left, 25th Mar., 1892-Accepted, 30th Apr., 1892
PROVISIONAL SPECIFICATION.
Improvements in Flyers used in Spinning Machines.
I, DAVID MOSELEY of the Chapelfield Works Ardwick, Manchester in the
County of Lancaster, Indiarubber Manufacturer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to flyers used in spinning machines and more particularly
to the flyers used in slubbing and roving frames, and its object is to ensure the
production of more regular and uniform roving and yarn, and also to reduce the
accumulation of "fly "and broken fibres and ends, and thus to enable the flyers to
run for longer periods without stopping to clean.
According to these improvements, line the hollow leg of the flyer with a
preferably slit vulcanite or ebonite tube having a tapered shape to fit the leg. This
tube by preference is moulded straight, and is heated to about the temperature
of boiling water or to such an extent as is necessary to make it flexible, in
which state it is bent and inserted into the leg of the flyer. On becoming
cool the tube regains its rigidity and is found to be firmly fixed, but it may be
easily removed when required to be replaced or for any other purpose, after
re-heating it.

COMPLETE SPECIFICATION.
Improvements in Flyers used in Spinning Machines.
I, DAVID MOSELEY of the Chapelfield Works, Ardwick, Manchester in the
County of Lancaster, Indiarubber Manufacturer, 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:-
This invention relates to flyers used in spinning machines, and more particularly
in slubbing and roving frames, and its objects are to secure the production of more
regular and uniform roving and yarn, and to reduce the accumulation of "fly" and
broken fibre and ends, and thus to enable the flyers to run for longer periods
without stopping to clean.
According to these improvements I line the hollow leg of the flyer with a
preferably slit vulcanite or ebonite tube having a tapered shape to fit the leg.
This tube is by preference moulded straight, and is heated to about the temperature
of boiling water or to such an extent as to make it sufficiently flexible, in which
state it is bent and inserted into the leg of the flyer. On becoming cool, the
tube regains its rigidity and is found to be firmly fixed, but it may be easily
removed when required to be replaced or for any other purpose, after re-heating it.
In case the tube should be buckled or distorted in bending this distortion may be
removed by means of a heated iron or metal tool shaped to enter the bend, which
is used to re-soften the ebonite and press it into shape and into contact with the
wall of the leg. If however the ebonite lining tube is constructed in two lengths,
this difficulty should it exist, will be greatly reduced or eliminated. In this case,
the straight portion of the tube may be inserted through a hole formed in the outer
surface of the bend of the hollow leg, and the bent portion, which may be moulded
by any suitable means to the desired curvature, may be inserted through the upper
entrance to the hollow leg.

page_text: The accompanying drawings illustrate in what manner my said invention may be
carried into effect.
In these drawings-
Figure 1 represents a sectional elevation of a flyer with, the ebonite lining tube
therein;
་
Figure 2 a sectional elevation of the upper part of the tube; and
Figure 3 a similar elevation of the lower part.
A is the hollow leg of the flyer; B the upper portion of the lining tube; C the
lower portion of the tube; D the upper entrance to the hollow leg; and E the
hole which is formed in the wall of the leg for the insertion of the part C when
the tube is formed in two portions.
As already described, if the tube be formed in a single length, it is moulded by
heat or otherwise to the desired form and is inserted into the 'hollow leg through
the opening D, while warm. If the tube be formed in two portions, the lower
portion is first inserted through the hole E, and the upper portion B, having been
heated, is inserted through the opening D. It is preferred to form the opening E,
when used, a short distance above the point of junction of the two parts of the
lining tube, so that it may be completely closed by the part B.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is,
In flyers for spinning machines, ebonite linings for the hollow legs, constructed
and arranged substantially as hereinbefore described and as illustrated by the
accompanying drawings.
