Improvements relating to the Spindles of Spinning and Twisting
Frames.
I, ALFRED GRUSCHWITZ, of Neusalz-on-the-Oder, in the Empire of Germany,
Manufacturer, 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 :-
My invention relates to an improved ring frame for spinning and twisting, which
combines the advantages of the flyer and those of the customary ring and traveller
while obviating the defects of these two systems.
The ring of this frame runs upon balls and therefore permits of a very great
number of revolutions, use being made of any desired drag device; this renders
the frame specially suitable for spinning and twisting flax, hemp and the like, for
which purpose the ring and traveller frame heretofore used has scarcely been
employed, because, although permitting of a very great number of revolutions it
is so badly constructed as regards the drag that in order to effect a change in the
dragging action the traveller requires to be exchanged, and that a heavy thread
either cannot be subjected to the drag action at all or only with great difficulties
and by reducing the number of revolutions.
For spinning and twisting flax, hemp and the like use has heretofore mostly
been made of flyers which fulfil the requirements as regards the application of the
drag, but admit of only a limited number of revolutions, which number is doubled
with the use of the improved ring frame.
In the accompanying drawing I have shown how my said invention may be
carried into practice.
Figure 1 represents a section of the ring with the spindle and spool.
Figure 2 shows a side view of the ring and spindle with the spool.
Figure 3 is a plan of the lower bearing for the balls.
Figure 4 is a view from below of the upper bearing for the balls.

a designates the rotary ring; a' the balls; the socket or spool; c the spindle;
d the thread; e the upper bearing; e the lower bearing; the cover for the oil
channel of the lower bearing; g the oil cup for the upper ball bearing; h a bolt
and a jointed bolt.
The rotary ring a which surrounds the spindle c and the spool b runs between
the bearings e and e¹ upon balls a¹ and sets the spindle c with the spool b indirectly
in motion, that is to say by the thread, so that the drag can be applied to the spindle
at will.
The operation is as follows: The thread d is conducted through one of the
apertures provided in the upper part of the ring a and is wound upon the spool or
socket b. While the ring is set in rapid rotation by the drum with the aid of a
cord, the spindle together with the spool or socket fixed thereon is set in motion
only by the traction of the thread and a drag applied thereto for the purpose of
maintaining the proper tension of the thread, the said drag being arranged on the
spindle frame and either adjusted by hand or operated automatically.
With this ring frame I obtain in the spinning and twisting of flax, hemp and
the like at least double the number of revolutions and therefore double as great a
productiveness as with flyers and the like, while the twisting is found to be better
and more uniform than heretofore.
In order to obviate the heating of the balls and bearings, which is liable to
occur when running at a great number of revolutions, I provide on the upper
bearing an automatic lubricator g, and construct the lower bearing so that
D

page_text: the oil thrown sideways into the space a² by the centrifugal power flows back
through the notches a³ and is caught up and again and again conducted to
the balls; it will thus be sufficient to provide the bearing with oil only once
a day.
The principal advantages of the improved ring frame are that it is particularly
adapted for spinning and twisting flax, hemp and the like, because it permits of
properly applying the drag also when running at a great number of revolutions and,
while operating with facility and certainty, increases the productiveness to double
the usual amount.
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 :-
:―
A ring frame for spinning and twisting, in which the ring is supported upon
balls for the purpose of reducing the friction, the spindle which winds up the
thread being actuated not by a cord or band but solely by the thread.
