PROVISIONAL SPECIFICATION
Improvements in and in the Manufacture of Spindles and Flyers
for Textile Machinery.
I, JOHN RICHARDSON, Steel Pin Maker, of Shaw House, Headingley, in the
County of York, do hereby declare the nature of this invention to be as follows:-
:―
My invention consists in the nature of the materials used, and the methods of
construction employed in the manufacture of Spindles and Flyers such as are
employed in Textile machinery for the process of spinning Flax, Cotton, Silk,
or other analogous materials; with the object of reducing the time and labour
which are required at present in the ordinary methods of producing the same.
In describing my Invention, I will take the question of the Spindles first. Each
of these when finished, is usually made of three different diameters, the largest
being at the bottom when the Spindle is revolving in its vertical position. By the
ordinary methods, these Spindles are usually made from round rolled steel bars,
which have (1) to be cut into suitable lengths as required; then (2) each such
length is heated in a hearth or furnace and drawn out for part of its length under
a high speed forging hammer to a smaller diameter; after which it is (3) again
heated and one part of it still further reduced to a still smaller size, the Spindle
then being in three different diameters; it is then (4) turned up in a lathe to
the diameter required. Finally, it is ground up smooth by swiftly revolving
stones, and polished with clams and emery.
My present Invention is designed to dispense altogether, or very nearly so, with
those parts of the ordinary process described 1, 2, 3, and 4, as above; and I
therefore propose making these Spindles each cast metal, preferably of steel, .e.
steel castings suitably annealed, which shall be made of the finished size required
all ready for grinding and polishing, and by this means dispense with all or
nearly all the time and labour now required for forging and turning them in the
ordinary way. To ensure securing sound and clean castings, I propose casting
these Spindles if necessary, in a vertical position.
With respect of the Flyers. As these are made in the present system, they
require an even larger proportionate amount of time to be expended on their
accurate forging and tooling before being ready for fitting to the Spindles. In
the case of these also, (as with the Spindles) I propose to dispense almost if not
entirely with the ordinary forging and tooling required in making these Flyers,
by having them made of cast steel, i.e. steel castings suitably annealed, and in
which castings the hollow groove or funnel required in one or both of the arms
of the fork through which the thread passes, can be taken out with a suitable core.
It will thus be seen that by my process these Flyers can be more accurately
balanced and proportioned; as, being cast from a pattern or model, and of cast
metal, they will be uniform in shape, size, and weight; thus not only dispensing
with the ordinary time and labour of forging and tooling, but also requiring less
time for the finishing of them and fitting them to the Spindles.
These steel castings may be made of such a quality that where and when neces-

page_text: sary, any part of these Spindles or Flyers can be moulded, forged, or hardened
as required.
My Invention therefore is designed to reduce the time and labour required for
the production of these Spindles and Flyers, by dispensing with the ordinary
methods of forging and tooling them; and replacing such forged articles by cast-
ings of steel suitably annealed, and which can be made uniform in shape, size,
and weight; and I propose to carry it out substantially as herein described.

Improvements in and in the Manufacture of Spindles and Flyers
for Textile Machinery.
I, JOHN RICHARDSON, Steel Pin Maker, of Shaw House, Headingley, in the
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:—
My Invention consists in the nature of the materials used, and the methods of
construction plyed in the manufacture of Spindle and Fler ch as are
employed in Textile machinery for the preres of spinning F. Cation, Sk,
or other analogous materials; with the object of reducing the time and labour
which are required at present in the ordinary methods of producing the same.
In describing my Invention, I will take the question of the Spindles first. Each
of these when finished, is usually made of three different diameters as shown
at A, a, and a³, in Fig. 1, the largest A being at the bottom when the Spindle
is revolving in its vertical position. By the ordinary methods, these Spindles
are usually made from round rolled steel bars, which have (1) to be cut into suit-
able lengths as required; then (2) each such length is heated in a hearth or
furnace and drawn out for part of its length under a high speed forging hammer
to a smaller diameter as at a¹; after which it is (3) again similarly heated and
one part of it still further reduced to a smaller diameter as at a³, the Spindle
then being in three different diameters; it is then (4) turned up in a lathe to the
diameter required. Finally, it is ground up smooth by swiftly revolving stones,
and polished with clams and emery.
My present Invention is designed to dispense altogether, or very nearly so, with
those parts of the ordinary process described 1, 2, 3, and 4, as above; and I
therefore propose making these Spindles each of cast metal, preferably of steel, i.e.
steel castings suitably annealed, which shall be made of the finished size required,
all ready for grinding and polishing, and by this means dispense with all or
nearly all the time and labour now required for forging and turning them in the
ordinary way. To ensure securing sound and clean castings, I propose casting
these Spindles if necessary, in a vertical position.
With respect to these Flyers. As they are made in the present system, they
require, an even larger proportionate amount of time to be expended on their
accurate forging and tooling before being ready for fitting to the Spindles. In
the case of these also, (as with the Spindles) I propose to dispense almost if not
entirely with the ordinary forging and tooling required in making these Flyers,
by having them made of cast steel, i.e. steel castings suitably annealed, and in
which castings the hollow groove or funnel required in one or both of the arms
of the fork through which the thread passes can be taken out with a suitable core.
Figures 3, 4, 5, 6, and 7 show the different processes of forging these Flyers

page_text: in the ordinary way; D and E being sectional views respectively of Figs. 4 and 6.
I propose making any one of these of cast steel so that the process of forging may
be reduced or entirely dispensed with; but I preferably make these Flyers in steel
castings as shown in Figures 8 and 9 when the groove can be cast in as shown in
Section F of Figure 8 which can afterwards be closed like Section G in Figure 9,
the arms of the Flyer being afterwards bent down as shown at B in Figure 1.
It will thus be seen that by my process these Flyers can be more accurately
balanced and proportioned; as, being cast from a pattern or model, and of cast
metal, they will be uniform in shape, size, and weight; thus not only dispensing
with the ordinary time and labour of forging and tooling, but also requiring less
time for the finishing of them and fitting them to the Spindles.
These steel castings may be made of such a quality that where and when neces-
sary, any part of these Spindles or Flyers can be moulded, forged, or hardened
as required.
My Invention therefore is designed to reduce the time and labour required for
the production of these Spindles and Flyers, by dispensing with the ordinary
methods of forging and tooling them; and replacing such forged articles by cast-
ings of steel suitably annealed, and which can be made uniform in shape, size,
and weight; and I propose to carry it out substantially as herein described.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:.
1. The making of Spindles for Textile Machinery which shall be steel castings
suitably annealed.
2. The making of such Spindles to be cast in steel and of different diameters as
required.
3. The making of Flyers as used with Spindles for Textile Machinery, such
Flyers to be made of steel castings which can afterwards be forged, moulded,
and suitably annealed as required.
