IMPROVEMENTS IN THE CONSTRUCTION OF THE SPINDLES AND FLYERS USED IN MACHINES FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES
Year: 1884

page_text: I, THOMAS ASHWORTH of Woodlands Davyhulme near Manchester in the county
of Lancaster, Cotton Spinner do hereby declare the nature of my invention for
IMPROVEMENTS IN THE CONSTRUCTION OF THE SPINDLES AND FLYERS USED IN
MACHINES FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES
to be as follows:-
I employ a fixed spindle carried in a rail at or near the bottom thereof, which
rail is capable of a rising and falling motion for winding on the yarn in the usual
manner.
Near the top of this fixed spindle is fixed or formed a disc to carry the bobbin.
The latter does not touch the spindle but is carried by a long tubular shell or
sleeve.
This shell also does not touch the spindle but has fixed within it a thin spindle
which runs inside the hollow upper portion of the fixed spindle and is made with a
point at the lower end running in a footstep formed at the lower part of the hollow
in the fixed spindle. This thin spindle is turned to a smaller diameter in the
middle portion so that it only bears at top and bottom on the inside of the hollow
upper portion of the fixed spindle.
By this means the bobbin runs perfectly free and may be run at a great speed
being supported upon a point which may run in oil without fear of any oil getting
onto the bobbin or the yarn.
The flyer is inverted and is attached to a tube carried by two fixed rails and
provided with a wharve by means of which it is driven by a band. This tube
revolves in bushes and runs perfectly free of the fixed spindle.
The lower fixed rail is provided with a long tubular collar or fixed bearing which
acts as a support to the fixed spindle, extending up inside the tube of the flyer,
which tube however does not touch the long collar but runs quite free of it.
The flyer legs are made about two inches longer than required and are bent or
doubled down so as to bring the curl about two inches below the bend. Or, if
preferred a fixed curl may be applied to the flyer leg about two inches from the
end which is then only bent over.
Thus it will be seen that both the bobbin and the flyer can run at a very great
speed without communicating any vibration to the fixed spindle as they both run
perfectly free and do not touch the fixed spindle.

page_text: I THOMAS ASHWORTH of Woodlands Davyhulme near Manchester in the County
of Lancaster Cotton Spinner do hereby declare the nature of my said invention
for "IMPROVEMENTS IN THE CONSTRUCTION OF THE SPINDLES AND FLYERS USED
IN MACHINES FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS
SUBSTANCES," and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :—
My invention is chiefly applicable to machines wherein the spindles are fixed;
the object being to enable the bobbin and flyer to be run at a very high speed without
communicating any vibration to the fixed spindle.
The nature of my invention and the manner in which the same is to be carried
into practical effect will be readily understood on reference to the accompanying
drawings and the following explanation thereof.
Fig 1. is a vertical section of a spindle and bobbin without the flyer, and
Fig. 2 is a similar view of the same with the flyer all complete, the spindle
(although what is called a "dead spindle") not being absolutely fixed, but mounted
as hereinafter described so as to be capable of a modified amount of motion.
The spindle a, a is carried in a rail b, b at or near the bottom thereof which
rail is capable of a rising and falling motion for winding-on the yarn in the usual
manner.
"
Near the top of the spindle a, a is fixed or formed a disc c, c to carry the
bobbin d, d. The size of the disc varying according to the amount of "drag
required on the said bobbin. The latter does not touch the spindle a, a but is
carried by a long tubular shell or sleeve e, e.
This shell e, e also does not touch the spindle a, a but has fixed within it a thin
spindle or peg ff which runs inside the hollow upper portion a³, a¹ of the fixed
spindle a, a and is made with a point at the lower end running in a footstep
formed at the lower part of the hollow in the spindle a, a.
The thin spindle or peg ff is turned to a smaller diameter in the middle portion,
so that it only bears at the top and bottom on the inside of the hollow upper
portion a', a¹ of the spindle a, a. By this means the bobbin d, d runs perfectly
free and may be run at a great speed being supported upon the point which
may run in oil without fear of any oil getting onto the bobbin d, d or the yarn.
In some cases I propose to run the shell or sleeve e, e on a point at the top of
the spindle a, a as shown at Fig. 3. The shell e, is prevented from being pulled
off the spindle when doffing the bobbins by means of a split spring ring jj (seen
also at detached view Fig. 5) or the same object may be obtained by means of a
Cap o, o attached by means of a bayonet slot and pin as shown at Fig. 4.
The flyer g, g is inverted and is attached to a tube h, h carried by two fixed
rails and provided with a wharve k, k by means of which it is driven by a
band. This tube h, h revolves in bushes, and runs perfectly free of the
spindle a, a (see also detached view Fig. 6.)
The lower fixed rail i*, is provided with a long tubular collar m, m which acts
as a support to the spindle a, a extending up inside the tube h, h of the flyer g, g
which tube however does not touch the long collar m, m but runs quite free of it.
In order to allow of the flyer being driven at a very high speed, instead of
absolutely fixing the spindle a, a tight in the rail b, b I attach at or near the
bottom of the spindle a block or weight n, n (as shown at Figs 1 and 2) the
bottom of this block bearing against the upper surface of the rail b, b so as to act

page_text: as a considerable drag upon the spindle but at the same time allow it to turn round
slowly in the event of vibration occurring and this turning of the spindle in the
rail instantly checks the vibration.
The flyer legs 9, 9 are made about an inch or more longer than usual and are
bent or doubled down at the top, the curl being about one inch or more below the
bend.
Thus it will be seen that both the bobbin and the flyer can be run at a very
great speed without communicating any vibration to the spindle a, a as they both
run perfectly free and do not touch the said spindle, and when the latter is not
absolutely fixed but is mounted as shown at Figs 1 and 2 and above described, even
if any vibration of the spindle should take place (when driving at very high
velocities) it will be at once corrected by the turning of the spindle in the rail b, b.
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
First The general construction of the spindles and flyers and their adjuncts
substantially as hereinbefore described and illustrated by the drawings annexed.
Secondly the combination of the fixed (or quasi-fixed) spindle with the revolving
tube carrying the flyer, supported in two fixed rails, the said spindle being
guided through the tube by the long tubular collar as shown and described.
And thirdly I claim the combination with such spindle and flyer of the loose
sleeve or shell carrying the bobbin and revolving on a point as shown and
described.
