1, ALFRED AMBLER, of the firm of Abraham Ambler and Sons, of Prospect Mills,
Wilsden, Yorkshire Spinners and Manufacturers, do hereby declare the nature of this
invention to be as follows:-
:-
In this class of machinery the twisting or folding of the fibres has hitherto taken
place at a point between the delivery rollers and the cap or ring and traveller,
consequently during the whole of the twisting process there has been tension on the
yarn, which I find to be a disadvantage, especially in the case of some descriptions
and counts of yarn.
The object of my invention is to put twist into the yarn while it is in a slack
condition, and before the full tension or drag is put upon it.
In order to carry out my invention I employ a tweezle placed at a suitable position
between the cap or ring and the delivery rollers. This tweezle is attached to the
under side of a rotary wharle, and the yarn on leaving the delivery rollers, passes
through a hole made vertically in the said wharle; from thence the yarn is conducted
to the tweezle attached thereto, and finally to the cap or ring, when it is wound onto
a tube, bobbin, or spool, in the ordinary manner.
By the employment of apparatus such as that above described, the tension on the
yarn is necessarily between the tweezle and the cap or ring, whilst the yarn above,
between the tweezle and delivery rollers, is comparatively without tension, and it is
this part of the yarn which receives the twist.
By this means a yarn is produced resembling yarn spun upon a mule. There are
also fewer breakages, and consequently less piecings and piecing up, allowing a
greater rate of production in a given time.
The wharle carrying the tweezle may be driven by the same band or tape which
drives the tube or spindle; an intermediate tension or guide pulley being employed,
for the purpose of tightening or slackening the band so as to stop the parts from
rotating; or separate bands and tin cylinders may be employed, as thought advisable.

page_text: Improvements in Cap and Ring Spinning Machinery.
I, ALFRED AMBLER, of the firm of Abram Ambler and Sons, of Prospect Mlls,
Wilsden, Yorkshire, Spinners, 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 :-
In this class of machinery the spinning of the fibres has hitherto taken place at a
point between the delivery rollers and the cap or ring and traveller, consequently,
during the whole of the spinning process, there has been tension on the yarn, which I
find to be a disadvantage, especially in the case of some descriptions and counts of
yarn.
The object of my invention is to put twist into the yarn while it is in a slack
condition, and before the full tension or drag is put upon it.
In order to carry out my invention I employ a tweezle placed at a suitable position
between the cap or ring and the delivery rollors. This tweezle is attached to the
underside of a rotary wharle, and the yarn, on leaving the delivery rollers, passes
through a hole made vertically in the said wharle, from thence the yarn is conducted
to the tweezle attached thereto, and finally to the cap or ring, when it is wound onto
a tube, bobbin, or spool, in the ordinary manner.
In order that my said invention may be better understood, I will now proceed to
describe the same more fully, and for that purpose make reference to the accompanying
sheet of Drawings, which is sectional elevation of a spinning frame having my
improvements applied thereto, wherein A is the framework of the machine having
spindles B and cap or ring C. D are delivery rollers which deliver yarn from
bobbins E to the spindle, all arranged in the ordinary manner. My improvements
are shewn at a, which comprises a tweezle or eyelet made secure on the underside
of the wharle made with a boss at each side for the purpose of being supported or
carried by brackets c and d, which extend full length of the machine. These parts
are shewn on an enlarged scale at Fig. 2, which is section, and Fig. 3 plan thereof,
wherein it will be seen that e represents a washer for receiving oil for lubricating the
said wharle, such washer being covered over by a brass or other metal cap f. The
wharle is driven by means of band or tape g, either from the tin cylinder which drives
the cap or ring, or from a separate tin cylinder; or the said wharle may be driven in
any other convenient manner. The yarn on coming from the bobbin E is passed
through the ordinary drawing rollers F and delivery rollers 1 through a hole / made
in the wharle which conducts the said yarn to the tweezle a and from thence to
the cap or ring C as indicated in the Drawings.
By the employment of the rotating wharle and tweezle such as that above described,
the tension on the yarn is necessarily between the tweezle a and the cap or ring C
whilst the yarn above, i.e. between the tweezles and the delivery rollers, is comparatively
without tension, and it is this part of the yarn which receives the twist.
By the employment of means above set forth, good yarn is produced resembling

page_text: that spun upon a mule, the apparatus also makes fewer breakages, consequently there
are less "piecings" and "piecing-up," thereby making a greater amount of yarn in
a given time than on the old system.
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 :-
In cap and ring spinning machinery the combination therewith of a rotating
wharle having a hole h therein eccentric with the axis, and a tweezle a on the
underside thereof for the purpose of dividing the tension on the yarn between the cap
or ring and the delivery rollers as herein described and shewn in the Drawings.
