PROVISIONAL SPECIFICATION.
Improvements in Doubling and Twisting Machines.
We, JULES DESIRE RYO, ALPHONSE MARIE RYO, and HECTOR RYO, all of
Roubaix (Nord) France, Machine Builders, and JOSEPH MARIE FELIU, of 3, Rue
Baños Nuevos, Barcelona, Spain, Manufacturer, do hereby declare the nature of
this invention to be as follows:-
:―
Our improvements relate more particularly to those doubling and twisting
machines in which the bobbin of doubled yarn is mounted on the twisting spindle
and from which it is directly wound off on to bobbins or cops or in hanks, etc.
Our invention consists essentially in causing the yarn when "ballooned" by the
action of centrifugal force to rub against a stationary ring in order that the friction
thus produced shall arrest the torsion of the yarn at this point and prevent it
reaching the bobbin from which the doubled yarn is being unwound and thus avoid
the effect which would otherwise be produced of limiting the degree of torsion of
the yarn.
The invention is illustrated in the accompanying drawings as applied to a spindle
driven by friction, but any other known arrangement of spindle.or mode. of driving
suitable for the purpose may be employed.
Figure 1 is a front elevation, and Figure 2 a side elevation,.of one of the spindles.
having the improvement applied.
Figure 3 is a part plan shewing the winding mechanism.
The spindle a is driven by a friction disc b and carries the bobbin of doubled
yarn c., Concentrically around the upper end of the spindle is mounted a ring d
which may be either plain or grooved and of any suitable section; fixed by means
of a bracket e to the rail f. The ring d.may however be otherwise mounted so
long as its height can be easily regulated. The centrifugal action on the yarnig,
resulting from the rotation of the spindle a, causes it to rub against the ring.d
which prevents the torsion of the yarn between said ring and the bobbin c and
prevents the kinking and consequent breakage of the yarn, the torsion taking place
between ring d and guide h whence the yarn passes, over a guide to the recipro-
cating winding-on guide & carried by bar 1, to the bobbiu m.

page_text: Our invention consists essentially in causing the yarn when "ballooned" by the
action of centrifugal force to rub against a stationary ring in order that the friction
thus produced shall arrest the torsion of the yarn at this point and prevent it
reaching the bobbin from which the doubled yarn is being unwound thus preventing
kinking and avoiding the effect which would otherwise be produced of limiting the
degree of torsion of the yarn.
The invention is illustrated in the drawings accompanying our Provisional
Specification as applied to a spindle driven by friction, but any other known
arrangement of spindle or mode of driving suitable for the purpose may be
employed.
Figure 1 is a front elevation and Figure 2 a side elevation, of one of the spindles
having the improvement applied.
Figure 3 is a part plan showing the winding mechanism.
The spindle a is driven at a high velocity by a friction disc b and carries the
bobbin of doubled yarn c. Concentrically therewith around the upper end of the
spindle is mounted a ring d which may be either plain or grooved and of any
suitable section, fixed by means of a bracket e to the rail f. The ring d may,
however, be otherwise mounted so long as its height can be easily regulated.
The centrifugal action on the yarn g, resulting from the rotation of the spindle a,
causes it to rub against the interior of ring d, which prevents the torsion of the
yarn between said ring and the bobbin c and the kinking and consequent breakage
of the yarn, the torsion taking place between ring d and guide whence the yarn
passes over a guide to the reciprocating winding on guide k carried by bar 1, to
the bobbin m.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
In a doubling and twisting machine in which the doubled yarns are wound off
from bobbins mounted on the twisting spindles, the combination with each spindle
of a stationary ring against which the doubled yarn being wound off is caused to
rub by centrifugal action in such manner as to prevent the torsion of the yarn
reaching the bobbin of the doubled yarn and causing kinks and breakages, as
specified.
