mprovements in the Construction of Spindles and Flyers used for
Spinning and Doubling Cotton and other Fibrous Substances.
I JAMES WILLIAM BULLOCK of 128 Frog Lane Wigan in the County of
Lancaster Book-keeper do hereby declare the nature of this invention to be as
follows:-
This invention relates to that class of spinning and doubling apparatus wherein the
spindle is fixed (or what is called a "dead spindle") and the flyer is in the form of a
cup or cylinder.
The principal object of the invention is to decrease the liability to vibration when
running at a very high speed which I propose to effect by shortening the spindle
as much as possible, and bringing the flyer and wharve close down onto the bolster
rail.
According to my invention as applied to the throstle I fix in the bolster rail a
flanged bolster screwed fast by means of a nut and provided with a tube or long collar
projecting upwards from the flange about four inches. The bottom and top of this
bolster and tube are fitted with brass bushes bored out to fit the spindle, the lower
end of which latter is fixed in the spindle rail.
The flange of the bolster which rests upon the bolster rail is provided with an oil
cup formed by soldering or forming thereon round the long collar a short tube about
half an inch deep.
The long collar is made, by preference slightly tapering upwards and with an
external spiral groove for lubricating purposes.
The flyer is made in the form of a cylindrical cup open at the top, and having
a tube fixed through the bottom (or made of one piece therewith) extending upwards
inside the cup to about the top of the same or rather higher.
The top of the cup is provided with one or more curls or eyes to carry the thread,
and the bottom thereof is made with a wharve for the driving band. The inner tube
of the cup is bored out to fit the outside of the long collar aforesaid the lower end
thereof resting on a washer in the bottom of the oil cup and revolving in the oil.
The bottom of the wharve is provided with an outer tube which fits outside the oil cup
and prevents the admission of dust or other extraneous matter.
The top of the spindle has fixed to it a tube closed at the top and open at the bottom,
and fitting over the inner tube, of the cup. The lower end of the spindle tube is
provided with a flange which allows the cup to run freely outside without
touching it.
The top of the spindle has a small hole bored down it and outside this tube fits
another light tube or shell also with a flange at the bottom and with a peg or pin
at the top inside, which runs in the small hole in the top of the spindle.

This outer tube or shell carries the bobbin and the necessary drag" may be
obtained by placing a washer of cloth or other material between the two flanges or by
the friction of the flanges themselves. A clip is arranged for the purpose of preventing
this outer tube or shell from being drawn off when doffing the bobbins.
By this arrangement the top of the bobbins will not be more than about five inches
above the level of the bolster rail and the spindle being proportionally shortened the
tendency to vibration is reduced to a minimum.
As a modification I propose sometimes to make the spindle rail a fixture and to give
the traverse motion to the bolster rail, in which case the driving band will have

page_text: to move up and down with the wharve, and the long collar will also be dispensed
with.

Improvements in the Construction of Spindles and Flyers used for
Spinning and Doubling Cotton and other Fibrous Substances.
1 JAMES WILLIAM BULLOCK of 128 Frog Lane Wigan in the County of
Lancaster Book-keeper 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 principally to that class of spinning and doubling apparatus
wherein the spindle is fixed (or what is called the "dead spindle") and the flyer is in
the form of a cup or cylinder.
The principal object of the invention is to decrease the liability to vibration when
running at a very high speed, which I propose to effect by shortening the spindle as
much as possible and bringing the "flyer" and "wharve" close down to the bolster
rail.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the drawings hereunto annexed and the following explanation thereof.
Fig. 1. represents in vertical section a spindle and flyer constructed according to
my invention, and Fig. 2. is a similar view of a modification thereof.
a is the fixed spindle, 6 the spindle rail to which the ordinary traverse motion for
winding the yarn upon the bobbin is given, and c the bolster rail.
According to my invention as applied to the throstle (see Fig. 1.) I fix in the
bolster rail ca flanged bolster d screwed fast by means of a nut e and provided with
a tube or long collar dx projecting upwards from the flange about four inches.
The bottom of the bolster d and the top of the tube d* are fitted with brass bushes f
bored out to fit the spindle a the lower end of which latter is fixed in or rests on the
spindle rail b.
The flange of the bolster which rests upon the bolster rail c is provided with an oil
cup g formed by soldering or forming thereon round the bottom of the long collar d
a short tube about half an inch deep.
The long collar d is made, by preference, slightly tapering upwards as shown at
Fig. 1. (or it may be parallel as shown at Fig. 2) and with an external spiral groove
for lubricating purposes as shown by the dotted lines.
The flyer is made in the form of a cylindrical cup open at the top, and having a
tube fixed through the bottom (or made of one piece therewith) extending upwards
inside the cup h to about the top of the same or rather higher.
The top of the cup is provided with one or more curls or eyes k which are
balanced at the opposite side by an equivalent weight of solder k* and the bottom
thereof is made with a wharve h* for the driving band.
The inner tube i of the cup is bored out to fit the outside of the long collar d* afore-
said, the lower end thereof resting on a washer in the bottom of the oil cup g and
revolving in the oil-cup.
The bottom of the wharve is provided with an outer tube g* which fits outside
the oil cup g and prevents the admission of dust or other extraneous matter.
The top of the "dead" spindle a has fixed to it a tube m closed at the top and
open at the bottom, and fitting over the inner tube i of the cup h but not touching it
so that the tube i runs freely inside it. The lower end of this spindle tube mis
provided with a flange m* which allows the cup h to run freely outside without
touching it.

page_text: The top of the spindle a has a small hole bored down it, and outside the tube m but
not touching it is another light tube or shell n also with a flange nx, at the bottom
and with a peg or pin o inside at the top which runs freely in the top g of the
spindle a.
This outer tube or shell n carries the bobbin p and the necessary drag may be
obtained by placing a washer of cloth or other material between the two flanges m*
and n* or by the friction of the flanges themselves.
A clip q is arranged for the purpose of preventing this outer tube or shell from
being drawn off when doffing the bobbins.
By this improved arrangement the top of the bobbins will not be more than about
five inches above the level of the bolster rail c and the spindle a being proportionally
shortened, the tendency to vibration is reduced to a minimum.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
-
The general novel construction and arrangement of spindle and flyer substantially
as hereinbefore set forth and illustrated by the drawings annexed and especially I
claim in connection with a long bolster tube fixed to the holster rail, and a cup-formed
flyer, the combination with the latter, of an inner tube running upon the bolster tube
and extending upwards inside the cup flyer to about level with the top of the same
whereby I am enabled to shorten the spindle and to bring the bobbin and flyer close
down upon the bolster rail and thus to diminish greatly the vibration of the spindle,
and flyer when running at high velocities.
