Improvements in Ring-spindles for Spinning-frames.
I, MATTHÄUS KOLB, of Viersen, in the Empire of Germany, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement: :-
My invention relates to ring spindles for spinning frames, and comprises a modifi-
cation in the usual arrangement of the ring and traveller of such spindles, which I
have devised for the purpose of rendering the latter available for the wet-spinning of
flax, tow and the like. An obstacle to the use of ring-spindles has heretofore been
that the glutin dissolved by wetting the thread with water soils the track of the ring,
and very rapidly causes the rusting of the same, giving rise to a jerky movement of
the traveller and consequently to an unequal tension of the thread, which increases
the liability of the latter to breakages and necessitates frequent renewals of the
travellers.
To obviate the rusting, the rings have indeed been made of brass or phosphor-
bronze in lieu of steel, but owing to the greater softness of the material they wear
proportionately quicker.
The modification devised for obviating the above-mentioned defects consists in
arranging the track and traveller vertically instead of horizontally as in the usual
arrangement, and combining two adjacent rings so as to form a double ring.
In the accompanying drawing
Figure 1 illustrates a vertical section of my improved ring-spindle,
Figure 2 a transverse section of the double ring shown to full size scale, and
Figure 3 a plan of the double ring.
a designates the traveller, the ring, 6 the ring frame adapted to move up and
down, c the spindle provided with a pulley and cross-piece, and d the bobbin. In
Figure 2 a denotes the track, ẞ the groove therein for the passage of the thread, and y
the ring proper which embraces the track in the form of a narrow rim and which,
in the arrangements heretofore used presents the form of a short hollow cylinder
inserted into the ring frame, its upper rim being shaped so as to constitute the
track.
By reason of the vertical arrangement of the track and traveller, the latter, under
the action of the centrifugal force, will bear with nearly its entire inner surface
against the track, not merely with a small part of the same like the track arranged
horizontally as hitherto. As the bearing surface increase. the pressure exerted upon
any part of the same diminishes, therefore softer metal which does not rust can be
used for the rings without occasioning rapid wear. No great quantity of dirt can
collect either upon the track or upon the narrow rim of the rings, so that a defect is
obviated which gives rise to irregular tension and the consequent breakages of the
thread, and has hitherto constituted the chief obstacle to the rings being employed in
the wet-spinning of flax and tow.
Moreover, the narrow rim of the ring permits the latter to be made of a larger
liameter, so that the bobbins can hold more thread, and the work required for
emoving them is considerably reduced.
By combining two rings to constitute a double ring is gained the special advantage
hat water can be poured upon the place where the rims of the rings join, and as this
vater is carried away by the travellers in their passage over the said place it will
lissolve and wash away any glutin which may adhere to the travellers. The water
nay be poured upon the aforesaid place from time to time according to requirements,
se being made of a small watering-pot. A sufficient quantity of water will remain
here by adhesion for obtaining the desired object.

page_text: When the spinning-frame is washed the rings can be thoroughly cleansed with
little trouble of any little dirt which may adhere to them whereas this is impossible
in the case of the rings having an upper horizontal track as hitherto employed. For
this purpose it would be necessary to wipe the interior of the rings with a cloth,
which however is precluded by the spindles in the same.
Trials which I have made with the improved ring-spindle constructed according to
my said invention have proved beyond doubt that the above-mentioned advantages
are realized in practice.
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 :-
Ring spindles in which, by the combination of two adjacent rings r provided
with vertical tracks a so as to form a double ring, the travellers a arranged
vertically will in their rotary movements automatically take up small quantities
of the water poured upon the place where the rims of the said rings join for the
purpose of dissolving and washing away the glutin which may adhere to the said
travellers.
