IMPROVEMENTS IN OR RELATING TO MACHINERY FOR SPINNING, DOUBLING AND TWISTING FLAX, COTTON AND OTHER FIBRES

page_text: I THOMAS UNSWORTH, of 79 Piccadilly, Manchester, Lancashire, Machine Maker
do hereby declare the nature of said Invention for IMPROVEMENTS IN OR RELATING
TO MACHINERY FOR SPINNING, DOUBLING AND TWISTING FLAX, COTTON AND OTHER
FIBRES, to be as follows:-
The object of my Invention is to put twist into yarn thread or prepared fibre as
it is drawn from the bobbins,
In performing my Invention I construct the bobbin with a ring and traveller
the ring being secured to the head or upper flange of the bobbin in any convenient
manner and I prefer to make the portion of the bobbin between the barrel and the
ring concave.
In applying my Invention to an ordinary twisting frame I wind the desired
number of threads to be twisted together on to a bobbin with a ring and traveller
attached which bobbin is placed upon and secured to a spindle; the threads are
passed through the traveller, then through a guide eye to the twist rollers and on
to a throstle bobbin, or to a "cop" built with ring and traveller as required.
The spindles with the wound bobbins are driven from the front spindles and tho
yarn as it is drawn upward from these bobbins by the twist rollers receives by the
aid of the ring and traveller a certain amount of twist regulated by the speed at
which the spindle and wound bobbins revolve.
This improved mode of putting twist into the yarn as it leaves the bobbin
prevents "ballooning" and thus permits a higher speed and consequently increased
production, with a better twist in the yarn or thread.
In applying my Invention to what is known as an up twisting machine I dis-
pense with the flyers and mount my improved bobbins on revolving spindles: the
yarn or thread is put through the traveller and passes upward over the twist
rollers to the taking up bobbins on the top of the machine all the twist being put
into the yarn by the ring and traveller as it leaves the wound bobbins the object
being to obtain a greater production of yarn, as a much greater speed can be given
to the wound bobbins with the ring and traveller attached than to the wound
bobbins placed in flyers.

page_text: I have described my Improvements applied to twisting frames but it is obvious
that the novel arrangement of ring and traveller attached to bobbins can be readily
applied to machines for spinning and doubling.
In place of securing the rings and travellers to the bobbins they may be placed
over the wound bobbins and the twist put in as the yarn is coming off the
bobbins.

page_text: COMPLETE SPECIFICATION,
I THOMAS UNSWORTH, of 79 Piccadilly, Manchester, Lancashire, Machine Maker,
do hereby declare the nature of said Invention for "IMPROVEMENTS IN OR
RELATING TO MACHINERY FOR SPINNING, DOUBLING, AND TWISTING FLAX, COTTON,
AND OTHER FIBRES," and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
The object of my Invention is to put twist into yarn, thread, or prepared fibre as
it is drawn from the bobbins.
In performing my Invention I construct the bobbin with a ring and traveller,
the ring being secured to the head or upper flange of the bobbin in any convenient
manner and I prefer to make the portion of the bobbin between the barrel and the
ring convex,
**
In applying my Invention to an ordinary twisting frame I wind the desired,
number of threads to be twisted together on to a bobbin with a ring and traveller
attached, which bobbin is placed upon and secured to a spindle; the threads are
passed through the traveller, then through a guide eye to the twist rollers and on
to a throstle bobbin or to a "cop" built with ring and traveller as required. The
spindles with the wound bobbins are driven from the front spindles and the yarn as-
it is drawn upward from these bobbins by the twist rollers receives by the aid of
the ring and traveller a certain amount of twist regulated by the speed at which
the spindles and wound bobbins revolve.
This improved mode of putting twist into the yarn as it leaves the bobbin
prevents "ballooning" and thus permits a higher speed and consequently increased.
production with a better twist in the yarn or thread.
In applying my Invention to what is known as an up twisting machine I dis-*
pense with the flyers and mount my improved bobbins on revolving spindles; the
yarn or thread is put through the traveller and passes upward over the twist
rollers to the taking up bobbins on the top of the machine, all the twist being put
into the yarn by the ring and traveller as it leaves the wound bobbins, the object
being to obtain a greater production of yarn as a much greater speed can be given
to the wound bobbins with the ring and traveller attached than to the wound
bobbins placed in flyers.
And in order that my Invention may be fully understood and readily carried
into effect I will describe the accompanying Sheet of Drawinga, reference being had
to the figures and letters marked thereon.
Figure 1 is a side sectional elevation of part of an ordinary twisting frame to
which my Improvements are applied. Fig. 2 shows a winding on bobbin with a
ring and traveller instead of a flyer as shown in Fig. 1. Fig. 3 is a side sectional
elevation of part of an up twisting frame with my Improvements applied. Figs. 4,
5, and 6 are views illustrating my improved method of constructing bobbins with
ring and traveller attached.
Similar letters refer to similar parts throughout the several views.

page_text: In Fig. 1. a is the frame which supports the spindles b upon which are
mounted and secured the wound bobbins c. Each bobbin c is or may be con-
structed as shown in Fig. 6, being convex at c¹ between the head and the barrel;
the bobbin is provided with a ring d and traveller e shown in plan in Fig. 4 and
in transverse section in Fig. 5, the ring & being secured to the head of the bobbin c
in any convenient manner. The yarn (or threads) ƒ passes from the bobbins c
(I refer only to one of the bobbins for the sake of clearness)-through the traveller e
and guide eye g over the guide rod and under the guide rod h¹ in the water
trough (when water is used) thence to the twist rollers j through the guide
eye to the flyer and so to the winding on bobbin m secured on the front
spindle n which drives its spindle b from the wharve n¹. Instead of having
flyers on the front spindles n I may have the ordinary rings and travellers as
illustrated by Fig. 2. In this case the threads f pass from the guide eyes k to the
travellers o in the ring rail p and thence to the bobbins m upon which they are
wound. The yarn ƒ receives a certain amount of twist from the ring d and
traveller e as it leaves the wound bobbin c the remainder of the twist being put
into the yarn either by the flyer 7 (Fig. 1) or by the ring and traveller (Fig. 2) as
the yarn is wound upon the bobbins m.
In Fig. 3 the yarn f passes upward from the wound bobbin c through the
travellers e over the guide rod r and round the twist rollers j over the lifting rod s
to the taking up bobbins t which are, mounted on the revolving spindles t¹.
In this arrangement all the twist is put into the threads f by the ring d and
traveller e as the yarn leaves the wound bobbins c.
I have described my Improvements applied to twisting frames but it is obvious
that the novel arrangement of a ring and traveller attached to a bobbin can be
readily applied to machines for spinning and doubling.
心
In place of securing the rings and travellers to the bobbins they may be placed
over the wound bobbins and the twist put in as the yarn is coming off the
bobbins.
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
1. Putting twist into yarn, thread, or prepared fibre by means of a ring and
traveller as the said yarn, thread, or prepared fibre is drawn from the wound
bobbin, substantially in the manner herein set forth for the purposes specified.
2. The combination with a bobbin à preferably made convex at c¹ of a ring d
and traveller e, substantially in the manner herein shown and described for the
purposes specified.
