PROVISIONAL SPECIFICATION.
Improvements in Flyers for Spinning Machines, and in the
Manufacture of the same.
We, EDGAR PERKS and HERBERT FERNIE trading as Thomas Perks and Sons
of 84 Vyse Street Birmingham in the County of Warwick Jewellers do hereby
declare the nature of the said invention to be as follows:
--
Our invention has for its object improvements in flyers for spinning machines
and in the manufacture of the same by which such articles are made much lighter
while having the same strength and wearing durability as those formerly in use while
the cost of manufacturing such articles is not materially increased. Flyers made
in accordance with our invention being so light thus effect a great saving of power
in their propulsion.
In carrying our invention into effect we cast our flyer of metal composed of the
greater part of aluminum but with sufficient of a harder metal combined to stiffen
it while the hollow side is first cast U shaped in section and the top upon which
the flyer is pivoted is cored. This casting is then placed in a tool having a mould
to fit it and is brought under pressure sufficient to compress the metal into a smaller
compass. The centre bearing is then drilled and the interior of the U shaped
section is machined to a smooth face after which the edges of the U are pressed
over to form a tube upon which the presser is mounted the necessary studs collars
or projections having been cast thereon to receive the same projecting ribs are
formed in the bends at each side at the top of the flyer to prevent any spring in the
sides taking place.

COMPLETE SPECIFICATION.
Improvements in Flyers for Spinning Machines, and in the
Manufacture of the same.
We, EDGAR PERKS, and HERBERT FERNIE, trading as Thomas Perks & Sons,
of 84 Vyse Street, Birmingham, in the County of Warwick, Jewellers, do hereby
declare the nature of our said invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
Our invention has for its object improvements in flyers for spinning machines
and in the manufacture of the same by which such articles are made much lighter
while having the same strength and wearing durability as those formerly in use
while the cost of manufacturing such articles is not materially increased. Flyers
made in accordance with our invention being so light, thus effect a great saving of
power in their propulsion.
In carrying our invention into effect we cast our flyer of metal composed of
the greater part of aluminium but with sufficient of a harder metal combined to
stiffen it while the hollow side is first cast U-shaped in section and the top upon
which the flyer is pivoted is cored. This casting is then placed in a tool having a
mould to fit it and is brought under pressure sufficient to compress the metal into a
smaller compass. The centre bearing is then drilled and the interior of the U-shaped

page_text: section is machined to a smooth face after which the edges of the U are pressed
over to form a tube upon which the presser is mounted, the necessary studs, collars,
or projections having been cast thereon to receive the same. Projecting ribs are
formed in the bends at each side at the top of the flyer to prevent any spring in
the sides taking place.
In order that our invention may be clearly understood and more easily carried
into practice we have appended hereunto a double sized sheet of drawings upon
which we have fully illustrated the nature of our said improvements together with
the mode of carrying the same into effect.
Figure 1, is a view of the casting as at first formed.

Figure 2, is a similar view of the flyer complete.

Figure 3, is a section on the line 1-2.
Figure 4, is a section on the line 3-4.
Figure 5, is a part elevation of one side of the flyer showing a modification in
the means for mounting the presser.
Figure 6, is a part section of the centre pivot on which the flyer turns.
Again referring to the drawings we cast the main body of our flyer in one piece
as shown by Figure 1 the part A¹ through which the fibre passes being cast to the
section shown by Figure 3, the metal of which we form the flyers being of
aluminium combined with say from 5 to 10 per cent. of a harder metal preferably
copper which gives the necessary amount of stiffness and strength with a great
reduction in weight over the old flyers. The blank as shown at Figure 1 is then
placed in suitable dies or moulds and sufficient pressure is brought to bear upon
it to stamp or press the metal into a smaller compass thus giving additional strength
and hardness to the various members. The hollow side A' is so cast to the section
shown so that the interior a³ can be thoroughly polished to a smooth surface this
being particularly necessary so as not to damage the fibre in its passage through
Bame. The centre pivot a is also cored out and afterwards drilled, the top part a
being bobbed to a smoother surface. The edges a³ of the hollow side A' are then
pressed over to the section shown by Figure 4 thus forming the hollow tube A¹
through which the fibre passes and upon which the presser B is mounted in the
ordinary manner such as shown by Figure 2 or studs a³ may be formed on the
flyer which is clipped by the collar 6 formed on the presser B, a shoulder being
provided on each side of the collar which forms a stop to and regulates the travel
of the presser B. Strengthening ribs a' are provided at the top of the flyer as
shown, to strengthen the bends and prevent any spring in the sides A or A'. The
socket at which forms the pivot upon which the flyer turns may be provided with
a hardened steel ferrule similar to that shown by Figure 6 to ensure a longer life to
the bearing.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The improvements in flyers for spinning machines and in the manufacture of the
same substantially as and for the purpose herein set forth and shown upon the
accompanying drawings.
