I, JOHN WALKER, of 70, Swan Lane, Derby Street, Bolton, in the County of
Lancaster, Machinist, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements upon the machine for which Letters Patent
were granted to Jonathan Bowden and John Walker, dated April 14th, 1892,
No. 7179, and on May 7th, 1898. No. 10484.
I now fix upon the first or driving shaft a rope or band pulley or wheel which
drives a shaft below by a rope or band pulley or wheel of such diameters as may be
required for the position and number of revolutions and on this second shaft I fix
another band pulley, for driving as below.
On the spindle rails, I fix projecting arms of a desired length, and in such a
position as to retain in bearings fixed on arms, a shaft on which is a tin drum,
running the length of the spindle rails and parallel therewith.
This tin drum shaft I drive by the band passing from pulleys on the second
shaft above named over a pair of guide pulleys, fixed in the required position to
allow the spindle rails free scope to rise or fall as required, and the tin drum shaft to
revolve in whatever position the spindle rails may be.
The tin drum shaft is so arranged as to allow for easy changing of the pulleys, for
any number of revolutions required.
On the bottom spindle rail in place of the footstep as in Specifications Nos. 7179
of 1892, and 10484 of 1898, above referred to I fix a bolster on which revolves a disc
or wharve pulley, which I drive either from the tin drum fixed on the projecting
arms, or by skewed gearing, if the twisters or disc on the disc beam above are so
driven.
I make the disc or wharve with a cone top and a hole bored in the centre in which
I fix the spindle with a recessed collar, on it, which rests on the cone. As the disc
or wharve revolves it carries the spindle with it, either to the right or left as
required.
By this improved arrangement I drive the spindles and wind the yarn on them,
as twisted by twisters and given off by the rollers, and by so doing I get a perfect
yarn, and a perfect build of cop on the bare spindle, or on a tube or bobbin, as may
be preferred.

I, JOHN WALKER, of 70, Swan Lane, Derby Street, Bolton, in the County of
Lancaster, Machinist, 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 upon the machine for which Letters
Patent were granted to Jonathan Bowden and John Walker, dated April 14th, 1892,
No. 7,179, and on May 7th, 1898, No. 10,484.
The nature of my said improvements and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to the
sheet of drawings hereunto annexed and the following explanation thereof.
Fig. 1 on the drawings is an end view (partly in section) of so much of a spinning
frame as is necessary to illustrate my present improvements. Fig. 2 is a partial
front elevation of the same, and Fig. 3 a plan view of the driving end. Fig. 4 is
a sectional elevation of the spindle and its adjuncts detached and drawn to a
larger scale.
According to my present improvements I now fix upon the first or driving shaft a
a rope or band pulley or wheel b which drives a shaft c by a similar pulley or wheel
of such diameter as will be required for the position and number of revolutions, and
on this second shaft c I fix another band pulley & for driving as hereinafter
described.
On the spindle rails e I fix a series of projecting arms f of a desired length and in
such a position as to carry, in suitable bearings fixed on the said arms, a shaft g
on which is a tin drum running the length of the spindle rails e and parallel
therewith.
The tin drum shaft g I drive by a band passing from the pulley dx on the second
shaft c above named over a pair of guide pulleys fixed in the requisite position to
allow the spindle rails e free scope to rise or fall as required, and the tin drum shaft g
to revolve in whatever position the spindle rails e may be.
The tin drum shaft is so arranged as to allow for easy changing of the pulleys
for any number of revolutions required.
On the bottom spindle rail e (see Fig. 4) in place of the footsteps as in Specifica-
tions Nos. 7,179 of 1892, and 10,484 of 1898 above referred to I fix a bolster k on
which revolves a disc or wharve pulley which I drive either from the tin drum /
carried on the projecting arms f, or by skewed gearing if the twisters or discs m on
the disc bean 12 are so driven.
I make the disc or wharvel with a cone top 1x through the centre of which is
bored a hole fitting loosely on the spindle o on which latter is tightly fixed a collar p
provided underneath with a conical recess which rests on the cone * so that as the disc
or wharve revolves it carries the spindle o with it either to the right or left as
required.
The lower end of the spindle o is carried by the footstep q the height of which
can be adjusted by means of the screw r so as to give more or less friction between
the two cones.
By the use of this or similar friction gear between the driving wharve and the
spindle I am enabled to adjust and drive the spindles and to wind either coarse or
fine counts of yarn on them at the saine ratio, as it is twisted by the twisters and
given off by the rollers, and by so doing I can produce a perfect yarn, and a perfect
build of cop either on the bare spindle or on a tube or bobbin as may be
preferred.

page_text: 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 :-
1. The improvements in spinning and doubling yarns from cotton and other fibrous
substances, consisting in the method of driving the spindle from the wharve by
suitable friction gear combined with means for adjusting the same, instead of
fixing the driving wharve rigidly on the spindle so as to drive the same direct as
hitherto practised.
2. The combination, with the wharve of a spinning and doubling frame, of a
conical top fitting inside the conical recess of a collar p fixed tightly on the
spindle, with means such as the screw r for adjusting the amount of friction
between the two cones, substantially as herein before described & illustrated by
Fig. 4 of the drawings annexed.
