Improvements in or relating to Spinning.
We, JAMES LONGMORE, Mill Manager, and WILLIAM LIVINGSTONE WATSON,
Merchant, both of 34, Leadenhall Street, London, E.C., do hereby declare the
nature of this invention to be as follows:-
This invention relates to spinning and consists in effecting the spinning and
twisting by means of a ring not a stationary ring such as is used in ordinary ring
spinning but one which is positively rotated and in which the fibres are carried in a
circular path by passing through a hole or equivalent yarn-guide formed eccen-
trically in or on the ring. The bobbin on to which the yarn or spun fibres is or are
wound instead of being positively driven as heretofore is driven merely by the
tension on the yarn between the ring and bobbin or may be driven positively if
desirable. To enable the yarn to be evenly wound on the bobbin the said bobbin
is suitably reciprocated through the central opening of the ring.
The drag on the yarn may be adjusted by a set screw or adjustable centre
bearing against the end of the spindle on which the bobbin is secured; or friction
or pressure may be applied to the spindle to impede or retard its rotation in some
other desired manner, or the drag may he regulated by the ordinary well known
means.
The ring has formed on one of its faces or sides a grooved pulley around which a
band or the equivalent is passed for driving it.
This arrangement admits of the positively driven part ric. -the ring being
made very short and compact so that it may be supported in only one bearing and
thus present very little friction; moreover by the working parts being contained
almost entirely within the bearing and having practically no unsupported parts
such as exist in ordinary spindles and flyers the ring may be rotated at a con-
siderably greater speed than has hitherto been practicable owing to the excessive
vibration caused. The output of a machine constructed according to this invention
in consequence of the high speed of rotation of the rings to be attained will be far
greater than in machines as hitherto constructed.
An advantageous way of supporting the ring is to groove its periphery and
mount it in an inversely grooved bearing and place balls in the space formed
between the two grooves; but instead of this bearing any other suitable bearing
may be provided. An advantageous method of construction is to cast the outer
grooved bearing and stand in one piece in glass, and the inner ring and bearing in
the same way, and the balls may also be of glass.
With the foregoing apparatus the yarn is subjected to very little friction and is
thus turned out in a smoother and more glossy condition than has been possible in
other machines where the yarn is subjected to considerably more friction.

Improvements in or relating to Spinning.
We, JAMES LONGMORE, Mill Manager, and WILLIAM LIVINGSTONE WATSON,
Merchant, both of 34, Leadenhall Street, London, E.C., 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 spinning and consists in effecting the spinning and
twisting by means of a ring not a stationary ring such as is used in ordinary ring

page_text: spinning but one which is positively rotated and in which the fibres are carried in a
circular path by passing through a hole or equivalent yarn-guide formed eccen-
trically in or on the ring. The bobbin on to which the yarn or spun fibres is or
are wound is driven merely by the tension on the yarn between the ring and bobbin
or may be driven positively if desired. To enable the yarn to be evenly wound on
the bobbin the said bobbin is suitably reciprocated through the central opening of
the ring.
The drag may be regulated by the ordinary well known means, or the yarn in
this method of spinning may be wound on positively by the differential motion well
understood.
The ring has formed on one of its faces or sides a grooved pulley around which
a band or the equivalent is passed for driving it.
This arrangement admits of the positively driven part viz. the ring, being made
very short and compact so that it may be supported in only one bearing and thus
present very little friction; moreover by the working parts being contained almost
entirely within the bearing and having practically no unsupported parts such as
exist in ordinary spindles and flyers the ring may be rotated at a considerably
greater speed than has hitherto been practicable owing to the excessive vibration
caused.
An advantageous way of supporting the ring is to groove its periphery and mount
it in an inversely grooved bearing and place balls in the space formed between the
two grooves; but instead of this bearing any other suitable bearing may be provided.
An advantageous method of construction is to cast the outer grooved bearing and
stand in one piece in glass, and the inner ring and bearing in the same way, and the
balls may also be of glass.
With the foregoing apparatus the yarn is subjected to very little friction and is
thus turned out in a smoother and more glossy condition than has been possible in
other machines where the yarn is subjected to considerably more friction.
In the accompanying drawings:
Figs. 1, 2 and 3 are respectively a side elevation, a plan and an end elevation of
apparatus constructed according to this invention, each view being shown partly in
section.
Like letters indicate like parts throughout the drawings.
A is the ring which may be of metal, glass or other suitable material and a is its
grooved edge or periphery. B is the bearing which may consist of the lower part
or stand b, upper part or cover b' and balls but if desired the parts b and b, may
be constructed in one piece and either of glass metal or other suitable material and
have suitable provision for the insertion of the balls which may also be of glass.
When the bearing B is formed with the two parts bb' these are secured together by
screws 6 or equivalent means.
a' is a grooved pulley formed on the face of the ring A and around which is passed
the band or the like which transmits rotary motion to the ring A. a² Fig. 3 is a
thread carrier which in the example illustrated in the accompanying drawings is in
the form of a recess but which if desired may be formed as an eye of wire, porcelain,
glass or equivalent material. C is the bobbin on which the yarn is wound and
which is fixed on the spindle C¹ in any convenient manner which will allow it when
full to be quickly removed so as to admit of a fresh or unfilled bobbin being placed
in position for winding.
When the apparatus is prepared for operation the yarn is passed from the usual
nipping rollers not shown in the drawing and through the thread carrier a³ and its
end is lapped around or moistened or otherwise made to adhere to the periphery of
the bobbin C. When the ring A is rotated in the direction of the arrow in Fig. 3
the yarn is carried round and the fibres are spun between the before mentioned
nipping roller and the ring, and the resulting spun yarn is wound on the bobbin C
which, to ensure the even distribution of the yarn is reciprocated in the central
opening of the ring A by the ordinary building motion. The pull on the yarn 'by
the ring A causes the bobbin C to rotate.

page_text: If desired the spindle C¹ may be a non-rotating one and the bobbin C may be
mounted so as to be able to rotate upon it, the necessary drag or retarding action
being in this case applied to the bobbin.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. Spinning or twisting fibres by means of a revolving ring which carries the
yarn in a circular path and winds it on a bobbin which is longitudinally reciprocated
through the central opening of the ring substantially as described and illustrated in
the accompanying drawings.
2. In a spinning or twisting machine a ring such as A mounted in a suitable
bearing such as B and having an eccentric yarn or thread carrier such as a² and a
pulley such as a substantially as described and illustrated in the accompanying
drawings.
3. In a spinning or twisting machine a revolvable ring such as A provided with a
yarn or thread carrier such as a² the circular path travelled by which is of less
diameter than that of the bearing within which the ring rotates and less than the
diameter of the driving pulley substantially as described.
4. In a spinning or twisting machine the combination with the ring A. having a
peripheral gooove a and the internally grooved block or bearing B of a ring or
set of balls 2 substantially as described and illustrated in the accompanying
drawings.
