Improvements appertaining to Spindles of Cap and like Spinning
Machines used in the Treatment of Yarns or Threads.
I FRED WALTON, of 104, Plaintrees Road, Laisterdyke, near Bradford, in the
County of York, Assistant Manager, do hereby declare the nature of this invention
to be as follows, that is to say: -
It relates to improvements appertaining to spindles of cap and like spinning
machines used in the production of yarns or threads, and consists in forming or
constructing the parts operating in connection with said spindles so that the
friction of the wharles on their bearings is greatly reduced, while further the
tubes upon which the bobbins are mounted are so constructed that they are enabled
to adjust themselves to the movements or vibrations of the dead spindles upon
which they are mounted.
In carrying my invention into effect I mount a sleeve upon the lifter rail of
the machine, said sleeve taking over the dead spindles and passing entirely through
or to the upper end of the wharle revolving thereon. Intervening between the
wharle and lifter plate is a cup or conical part which is adjustable lengthwise
of said sleeve by sliding or by being screwed thereon and which together with
the lower part of the wharle forms a ball race into which are placed a number of
anti-friction balls; or a suitably formed ring may be employed instead of said
balls. A similar antifriction bearing is formed by a fixed conical part at the
upper end of the sleeve and a cup formed on the upper part of the wharle. Or
if desired the cup or conical part of the lower antifriction bearing may be fixed
to the sleeve above described and the upper conical part adjustable thereon.
By this arrangement of parts a better bearing surface is afforded for the wharles,
while the friction caused by their rotation is greatly diminished.
The sleeve over which the bobbin is mounted is formed to have an annular
flange at its lower extremity, while loosely taking over said annular flange is
the part carrying the projections for engagement with the openings formed in
the bobbin, said part being mounted by a pin and slot or other suitable arrange-
nent upon a flange extending from the wharle. Or instead of said pin and slot
arrangement the parts may be secured by being screwed together. By thus con-
structing the several parts the sleeve or tube over which the bobbin takes is not
rigidly fixed nor driven positively and so it is enabled to adjust itself to any
movement or vibration of the dead spindle upon which it is mounted.

Machines used in the Treatment of Yarns or Threads.
I FRED WALTON, of 104, Plaintrees Road, Laisterdyke, near Bradford, in the
County of York Assistant Manager, do hereby declare the nature of this in-
vention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, that is to say:-
It relates to improvements appertaining to spindles of cap and like spinning 5
machines, used in the production of yarns or threads, and consists in forming or
constructing the parts operating in connection with said spindles so that the
friction of the wharles on their bearings is greatly reduced, while further the
tubes upon which the bobbins are mounted are so constructed that they are enabled
to adjust themselves to the movements or vibration of the dead spindles upon 1
which they are mounted.
In order that my said invention may be readily understood, I have hereunto
appended sheets of drawings illustrative thereof, to which, by figures and letters,
reference is made in the following description.
Fig. 1 represents a sectional elevation of my improvements as applied to the 1
spindle of a cap spinning machine.
Fig. 2 represents a front elevation of parts illustrated by Fig. 1.
Figs. 3 and 4 are similar views to Figs. 1 and 2 respectively but illustrate a
modification of my invention.
Fig. 5 is a similar view to Fig. 1, but illustrates a further modification of my 2
invention.
Figs. 6 7 and 8 are detail drawings hereinafter referred to.
Fig. 9 represents a sectional end elevation of a portion of a cap spinning frame,
drawn to a reduced scale, and shows my improved parts mounted in their opera-
ting positions therein.
Similar letters and figures of reference indicate similar parts throughout the
several views.
The class of spinning, twisting, and like machines to which my invention is
applicable are those in which the bobbins a for holding the yarn are rotated
around dead spindles b, and in the annexed drawings I have illustrated my
improvements as applied to cap spinning spindles, however it will be readily
understood that same may be applied with equally good results to other similar
classes of spinning twisting and like machines.
In carrying my invention into effect, I mount a sleeve cupon the lifter rail d
of the machine, said sleeve taking over the dead spindle 6 and passing entirely
through or to the upper end of the wharle e which revolves thereon.
Intervening between the wharle e and lifter plate is a cup f which
is provided with a conical part f₁ and is adjustable lengthwise of said sleeve c
by sliding or by being screwed thereon, this latter method being illustrated in
the drawings, and which, together with the lower part e¹ of the wharle forms a
ball race into which are placed a number of antifriction balls g. A similar bear-
ing is formed by a fixed conical part at the upper end of the sleeve c and a cup
formed on the upper end of the wharle e. The conical part f¹ of the cup may
be formed integrally with said cup as shown by Fig. 7, or it may be formed as a
separate part to slide or be screwed along the sleeve cas illustrated by Fig. 1.
If desired the cup f may be fixed to the sleeve e and the conical part c¹ of
the upper antifriction bearing be adjustable along the sleeve c, while the cup f
may form one part of the ball race, the corresponding conical part being formed
on the lower end of the wharle e, as illustrated by Fig. 5.

page_text: Instead of making use of the ball bearing as above described, I may place a
loose washer h, in the cup f for the wharle to revolve upon (see Fig. 3) the cup f
being either screwed upon the sleeve c or held against a shoulder formed on said
sleeve c by means of the nut k, since in this arrangement it is not necessary that
said should be adjustable.
cup
By these arrangements of parts a better bearing surface is afforded for the
wharles e, and the friction caused by their rotation is greatly diminished, while
further the cups f form receptacles for the lubricant and also prevent it from
being thrown outwards by centrifugal force to cause trouble and inconvenience
to the operator.
The sleeve m over which the bobbin a is mounted is formed to have an annular
flange m at its lower extremity, while loosely taking over said flange m¹ is the
coupling piece n carrying the projections n' for engagement with the openings
formed in the lower part of the bobbin a, a pin e fixed at the upper part of the
wharle taking within a slot n² formed in the coupling piece n in order that the
rotary motion of the wharle is thereby transmitted to the bobbin a, while said
bobbin rotates around the loose sleeve m. Instead of such pin and slot arrange-
ment, the coupling piece n may be screwed or otherwise connected to the wharle c,
while turther, the projections n' may be formed on the wharle itself and the
flange m take thereunder as shown by Fig. 3. By thus constructing the several
parts the sleeve or tube m is not rigidly fixed nor driven positively and so it
is enabled to adjust itself to any movement or vibration of the dead spindle a
upon which it is mounted. Although I have herein before described and illus-
trated my improved methods of supporting and driving the bobbins of cap and
similar spinning and like machines as applied to wharles and spindles having
my improved bearings it will readily be understood that I may apply this part
of my invention, to any ordinary wharles which will lend themselves to the
mounting thereon of such parts.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the said is to be performed, I declare that what I
claim is -
1. Bearings for the wharles of cap and similar spinning and like machines used
in the production of yarns or threads the same being constructed and arranged
to operate substantially as herein specified with reference to Figs. 1 and 2 of the
drawings.
2. Bearings for the wharles of cap and similar spinning and like machines used
in the production of yarns or threads, the same being constructed and arranged
to operate substantially as herein specified with reference to Fig. 5 of the drawings
3. Bearings for the wharles of cap and similar spinning and like machines
used in the production of yarns or threads, the same being constructed and
arranged to operate substantially as herein specified with reference to Figs. 3
and 4 of the drawings.
4. Means for supporting and driving the hobbins of cap and similar spinning
and like machines, the same being constructed and arranged to operate substan-
tially as herein specified with reference to Figs. 1 and 2 of the drawings.
5. Means for supporting and driving the bobbins of cap and similar spinning
and like machines, the same being constructed and arranged to operate substan-
tially as herein specified with reference to Figs. 3 and 4 of the drawings.
