Improvements connected with Flyer Spindles for Spinning
Machinery.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 6 Bream's Buildings,
Chancery Lane, in the County of Middlesex, Mechanical Draughtsman, do hereby
declare the nature of this invention to be as follows:-
This invention relates more especially to spindles and flyers for spinning rope-
yarn and twine, and for the manufacture of cordage, but is or may be also applicable
to spindles and flyers for other spinning and twisting operations.
The object of the invention is to maintain a proper tension of the yarn, twine, or
cordage, as it is wound upon a bobbin within the flyer by the rotation of the
latter.
In spinning machinery employed in the manufacture of rope yarn, it is a common
practice to drive the flyer, and to mount the bobbin on a drag spindle, using
mechanism of a more or less complex character for regulating the tension on the
yarn.
It is now proposed to mount the drag spindle which supports the bobbin in the
flyer, in a footstep formed on the bottom of a liquid-containing vessel.
On that part of the spindle within the said vessel, are provided vanes or blades
which are firmly secured to the spindle by suitable means, as, for instance, the said
vanes or blades being cast upon a hub which is secured by a set screw to the
spindle. Formed on the interior of the vessel are ribs or wings, which project
inwards just so far as to be clear of the rotation of the vanes or blades of the
spindle.
It
It will be understood that the rotation of the bobbin is due to the pull produced
upon it by the yarn, twine, or cord, as the latter, acting through the upper head of
the flyer, is wound upon the bobbin. The rotation of the bobbin produces the
rotation of the drag spindle, and consequently of the attached vanes or blades.
will now be understood that the rotation of the bobbin, caused by the drag of the
yarn which is led through the guides of the rotating flyer, is resisted by the vanes of
the drag spindle, immersed in the liquid in the vessel. This resistance produces a
proper tension of the yarn, twine, or cord, which is being wound upon the bobbin.
As the quantity of yarn, twine, or cord upon the bobbin increases, the bobbin is
caused to rotate faster, relatively to the flyer, the velocity of rotation of which is
uniform. At the same time, the increased quantity of yarn, twine, or cord upon the
bobbin, brings the pull or draught upon the latter at a greater distance from its
centre, and from this there would result a diminution of the tension of the yarn,
twine, or cord, but for the increased velocity of the rotation of the bobbin and
spindle, which is met by such necessary resistance in the liquid in the vessel to the
rotation of the vanes or blades, that an approximately uniform tension is produced on
the yarn, twine, or cord during the filling of the bobbin.
The purpose of the ribs on the interior of the vessel, is to prevent the liquid in
the vessel from being swirled around by the rotation of the vanes or blades, and
thereby to increase the resistance offered by the liquid to the rotation of the drag
spindle.

Improvements connected with Flyer Spindles for Spinning
Machinery.
1 ALFRED VINCENT NEWTON of the Office for Patents, 6 Bream's Buildings,
Chancery Lane in the County of Middlesex, Patent Agent, 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 more especially to spindles and flyers for spinning rope-yarn
and twine, and for the manufacture of cordage, but is or may be also applicable to
spindles and flyers for other spinning and twisting operations.
The object of the invention is to maintain proper tension of the yarn, twine or
cordage, as it is wound upon a bobbin within the flyer by the rotation of the
latter.
Fig. 1 in the drawing represents an elevation, partly in section, of an upright
flyer and spindle, to which the invention is applied.
Fig. 2 represents a horizontal section in the line a Fig. 1.
Fig. 3 represents a horizontal section in the line y y Fig. 1.
Similar letters of reference designate corresponding parts in the several Figures.
A designates a flyer of ordinary construction, having hollow journals a a¹ at its
top and bottom, fitted to rotate in journal boxes or bearings, which are to be
mounted in any suitable manner upon the framing of the machine upon which the
flyer is used. The side bars of this flyer are represented as having fitted to slide
upon them a ring A', which carries the traverse guide c. On the lower journal of
the flyer, below the bearing 61, is represented a pulley E, to receive a belt for
imparting rotary motion to the flyer.
B designates an upright spindle, passing through the lower hollow journal of the
flyer, and fitted to turn therein. designates a bobbin arranged within the flyer,
and attached to the said spindle.
The connection between the bobbin and the spindle, and the means of supporting
the bobbin and spindle in the flyer, may be of any well known kind.
In the example represented, the spindle terminates at a short distance above the
lower cross bar of the flyer, and has firmly secured to it a flanged head D, and the
bobbin is provided with journals d at its top and bottom. The lower journal d is
received in a bearing in the flanged head D of the spindle, and the upper journal d is
received within a removable socket e, which is capable of sliding up and down upon a
pin f, which is secured in the upper cross-bar of the flyer, and occupies a central
position therein, in line with the spindle. The said socket e has applied to it a
spiral spring g, which holds it down over the journal d, until the said socket is
raised by hand, for the purpose of liberating the journal d, when it is desired to
remove the bobbin from the flyer.
The bobbin and spindle are represented as connected, so as to be compelled to
rotate together, by means of a pin on the spindle head D entering a hole in a
plate i, which is secured to the bobbin, and which is represented as having one of
the journals d formed upon it. There may be a similar plate i at each end of the
bobbin, carrying its respective journal d, so that the bobbin may be placed in the
machine with either end downward.
The spindle B is prolonged beyond the lower journal of the flyer, and enters a
vessel F, which contains water or other liquid, and its lower end is represented as
received in a step bearing in the bottom of said vessel. Ou that part of the spindle
within the said vessel F, are provided vanes or blades k, which are firmly secured to
the spindle by suitable means, as, for instance, the said vanes or blades being cast
upon a hub, which is secured by a set screw to the spindle. On the interior of the
sides of the said the vessel, are provided stationary ribs or wings 1, which project
inwards, just so far that the vanes or blades k will just clear them in their rotation
with the spindle.

page_text: The only means provided for the rotation of the bobbin, is the pull produced upon
it by the yarn, twine, or cord m, as the latter, passing through the upper head of
the flyer and over the guides c c', is wound upon the bobbin by the rotation of the
flyer. The rotation of the bobbin thus caused, produces the rotation of the spindle,
and of the attached vanes or blades k. The rotation of the latter is resisted by the
liquid in the vessel F, in which they are immersed, and this resistance produces a
proper tension of the yarn, twine, or cord, which is being wound upon the bobbin.
As the quantity of yarn, twine or cord upon the bobbin increases, the bobbin is
caused to rotate faster relatively to the flyer, the velocity of rotation of which is
uniform. At the same time, the increased quantity of yarn, twine or cord upon the
bobbin, brings the pull or draught upon the latter at a greater distance from its
centre, and from this there would result a diminution of the tension of the yarn,
twine or cord, but for the increased velocity of the rotation of the bobbin and spindle,
which is net by such necessary resistance in the liquid in the vessel F to the
rotation of the vanes or blades k, that an approximately uniform tension is produced
on the yarn, twine or cord, during the filling of the bobbin.
The purpose of the ribs or wings on the interior of the vessel F, is to prevent
the water in the vessel from being swirled around by the rotation of the vanes or
blades k, and to increase the resistance offered by the water to the rotation of the
vanes or blades.
This improvement has the advantage of greatly simplifying spinning machinery
used in the manufacture of rope and cordage, in which the spindle as well as the
flyer are commonly separately driven, with a friction device between them, and
means for varying the said friction in proportion to the quantity of material upon
the bobbin, as it enables the driving mechanism for the spindle, and the variable
friction device between the bobbin and the spindle or their two mechanisms, to be
dispensed with.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
from abroad, I declare that what I claim is :-
1. The combination with a flyer and a spindle therein for a bobbin, and means of
imparting rotary motion to the flyer, of one or more rotary vanes or blades driven
by said spindle, and a liquid-containing vessel in which said blades or vanes work,
substantially as and for the purpose herein set forth.
2. The combination with a flyer and a spindle therein for a bobbin, and means for
imparting rotary motion to the flyer, of one or more rotary blades or vanes driven
by said spindle, and a liquid-containing vessel in which said vanes or blades work,
and which is furnished with inwardly projecting ribs, substantially as and for the
purpose herein set forth.
3. The combination with an upright flyer having a hollow journal at its bottom,
and a spindle for a bobbin passing through said journal, of vanes or blades attached
to said spindle below the flyer, and a liquid-containing vessel in which said vanes
work, substantially as and for the purpose herein described.
