Improvements in Spindles and Flyers used in Preparing, Spinning,
Doubling, and Twisting Cotton, Wool, Flax, Silk, and other
Fibrous Substances.
1, WILLIAM SUMNER, of 33, Rue du Bouclier, Ghent, in the Kingdom of
Belgium, Spindle and Flyer Maker, do hereby declare the nature of this invention
to be as follows:-
My improvements relate, in the first place, to the screw threads of spindles used
to fasten flyers thereon when spinning or doubling wet yarn or threads, which soon
become rusty and soon wear slack or loose in the flyer socket.
To remedy these defects and lessen or prevent this rust I coat the screw thread
with a fusion or plating of anti-rusting metal, such as, a fusion by heat of tin, zinc,
spelter or copper, or a mixture, by fusion containing two or more of the aforesaid
metals, to longer preserve the spindle thread in its fit to the flyer and producing
better work.
My improvements relate in the second place to solid leg flyers used in spinning,
doubling or twisting yarns, threads or cordage and has for its object to cause the
same to automatically guide and hold the sliver free from contact with the bobbin
heads.
To this end instead of forming the shoulders straight or in a true line with, or
across, the centre of the flyer socket, I bend backwards from at or near the flyer
socket, the shoulders or upper part of the flyer legs, so that the shoulder part near
its socket in its rotation is in advance of the leg portion of the flyer, thus giving an
advancing curve which passes or glides outwards the sliver or yarn to the top of
the flyer leg (if required I form a small recess at the top of the flyer leg). By this
arrangement I place more and better yarn upon the bobbins and keep the yarn free
from the bobbin heads.
My improvements relate in the third place to the long combined collar and foot
step of rabbeth spindles or other continuous running spindles and consists in
forming the same of sheet phosphor bronze or other sheet elastic metal, instead of
in cast solid metal as hitherto has been the case, which will lessen the cost of pro-
duction, keep the spindle cooler, render it not liable to break and enable it to run at
a higher speed with less wear. In its formation I turn inwards the sheet metal
about one inch from its lower or foot end, and at its upper end I turn outwards
about one inch and a quarter, then form on a mandrel to the size or shape required,
the part at the bottom turned inwards serves to form the footstep therein and the
part at the top turned outwards I leave it to be clastic and so as to fit the tube of
the frame rails.
To bend the metal I soften it at the parts to be bent only, which gives a most
durable and elastic combined footstep and collar and capable of being applied to
every description of rabbeth or other similar make of spindle.

Improvements in Spindles and Flyers used in Preparing, Spinning,
Doubling, and Twisting Cotton, Wool, Flax, Silk, and other
Fibrous Substances.
I, WILLIAM SUMNER, of 33, Rue du Bouclier,. Ghent, in the Kingdom of
Belgium, Spindle and Flyer Maker, 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 improvements in spindles and flyers used in preparing,
spinning, doubling, and twisting cotton, wool, flax, silk and other fibrous substances
and in order that my invention may be more fully understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Fig. 1 is an elevation of the upper end of a spindle, Fig. 2 a side view and Fig. 3
a plan of Fig. 2 of a flyer as heretofore has been in use.
Figs. 4 & 6 are side views and Figs. 5 & 7 plans thereof respectively of my
improved flyer.
Figs. 8 & 10 are longitudinal sections and Fig. 9 a plan of Fig. 8 of my combined
collar and footstep.
In carrying out my invention and referring to Figs. 1 & 2 the improvements
relate in the first place, to the screw threads a of spindles used to fasten flyers b
thereon when spinning or doubling wet yarn or threads, which soon become rusty
and soon wear slack or loose in the flyer socket.
To remedy these defects and lessen or prevent this rust I coat the screw thread a
with a fusion of plating of anti-rusting metal, such as, a fusion by heat of tin, zinc,
spelter, or copper, or a mixture, by fusion containing two or more of the aforesaid
metals, to longer preserve the same in its fit to the flyer b and producing better
work.
My improvements relate in the second place to solid leg flyers used in spinning,
doubling, or twisting yarns, threads, or cordage and has for its object to cause the
same to automatically guide and hold the sliver free from contact with the bobbin
heads.
In carrying out this part of my invention instead of forming the shoulders
straight or in a true line with, or across, the centre of the flyer socket 6', as shown
in Figs. 2 & 3, I bend backwards from, at, or near the flyer socket 6', the shoulders
or upper part of the flyer legs b, so that the shoulder part near its socket 6' in its
rotation is in advance of the leg portion of the flyer, thus giving an advancing
curve which passes or glides outwards the sliver or yarn to the top of the flyer leg
(if required I form a small recess at the top of the flyer leg 6'). By this arrange
ment I place more and better yarn upon the bobbins and keep the yarn free from
the bobbin heads.

In lieu of forming the upper part or shoulder as shown in Figs. 4 & 5, they may
be curved, as shown in Figs. 6 & 7.
My improvements relate in the third place to the long combined collar and foot-
step of rabbeth spindles or other continuous running spindles and consists in forming
the same of sheet phosphor bronze or other sheet elastic metal c,.preferably by
coiling. the sheet metal spirally see Figs. 8 & 9, instead of in cast solid metal as
hitherto has been the case, which will lessen the cost of production, keep the spindle
cooler, renders the combined footsteps and collars not liable to break and enable
the spindles to run at a higher speed with less wear. In its formation I turn
inwards the sheet metal about one inch from its lower or foot end c¹ and at its upper
end turn outwards about one inch and a quarter, then form the same on a
mandrel to the size or shape required, the part c' at the bottom turned inwards

page_text: serves to form the footstep therein and the part cat the top turned outwards I
leave it to be elastic and so as to fit the tube of the frame rails.
To bend the metal I soften it at the parts to be bent only, which gives a most
durable and elastic combined footstep and collar and capable of being applied to
every description of rabbeth or other similar make of spindle.
In lieu of forming the upper end c² of my combined collar and footstep, as shown
in Figs. 8 & 9, I dispense with the part bent outwards and attach to the collar by
soldering or otherwise, a section of a shell or tube d, as shown in Fig. 10, of
sufficient thickness to fit the frame tube.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is,―
"In spindles and flyers used in preparing, spinning, doubling and twisting cotton,
wool, flax, silk, and other fibrous substances."
1st. Coating the screw thread of spindles with an anti-rusting metal for the
purpose of preserving the same longer in use, substantially as set forth.
2nd. Bending the shoulder or upper part of the flyer legs in a direction opposite
in which the flyer turns, substantially as and for the purpose set forth.
3rd. The manufacture of combined footsteps and collars for rabbeth or other
continuous running spindles of elastic sheet metal, substantially as and for the
purpose set forth.
