Improvements in Ring Spinning Machines.
I, FRITZ FRIED of Arnan / Elbe Bohemia, do hereby declare the nature of this
invention to be as follows:-
In ring spinning machines such as ordinarily used, the ring rail moves up and
down in order that the yarn may be properly wound upon the bobbin. This has the
great disadvantage that the length of the thread being guided to the traveller of the
ring is continually changing causing a swaying of the thread which results very
frequently in its being broken.
In order to obviate this drawback, the ring rail is according to this invention made
stationary and the copping rail is caused to move up and down, so that each bobbin
ascends and descends within its ring, partaking at the same time of the rotation of the
spindle upon which it is mounted.
The annexed drawing illustrates an arrangement according to this invention.
The ring rail A, which carries the rings a, is stationary, whilst the copping rail B
which carries the collars b, and through which the spindles C pass freely, is caused by
suitable means to move up and down.
In order that the collar b may partake of the rotation of the spindle C, the latter is
provided with a longitudinal groove c into which enters the end of the screw 6.
During the upward and the downward movement of the rail B the screw b¹ slides in
the said groove.
The collar is provided at the top with a small projection & which enters into one of
the recesses formed in the under side of the bobbin D which is placed on the spindle C.
The bobbin is thus caused by means of the projection to partake of the rotary
movement of the collar b.
When commencing to spin yarn, the bobbin D is lifted off the projection &*, the
thread is placed on it in the usual manner, and the bobbin is then allowed to drop.
The bobbin falling by its own weight upon the collar b, is immediately caught by the
projection and caused to rotate with the spindle, the movement of which is not
interrupted.
The traveller d for the thread slides along the ring a.
In practice the spindles often vary in diameter, and the bobbins have holes or
openings of various sizes; hence it may happen that the bobbin, on being placed on

page_text: the spindle, bears against it, and is thus caused to rotate and does not drop immediately
on to the collar 6 when released. In order to obviate this, the collar is preferably
furnished with a tube or sleeve that surrounds the spindle and is of about the same
length as the bobbin. The bobbin instead of being placed direct on the spindle is
placed on the tube or sleeve, the diameter of which is made to correspond with that of
the hole or opening through the bobbin; thus the bobbin is prevented from coming
into contact with the spindle and its falling upon the collar 6 when released is
ensured.

I, FRITZ FRIED of Arnan / Elbe, Bohemia, Austria, 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:-
This invention relates to ring spinning machines and has for its object to obviate
the drawbacks occasioned by the variations in length of the portion of thread between
the drawing-frame and the bobbin, these changes of length being caused by the
reciprocating motion of the ring.
For this purpose according to this invention, the ring is made stationary and the
bobbin has imparted to it a reciprocating motion along the spindle, whereby the portion
of thread between the drawing-frame and the bobbin is maintained at an invariable
length as will readily be understood.
The annexed drawing is a sectional side elevation of a ring spinning frame
constructed according to this invention.
The ring, provided with a traveller as usual, is rigidly secured to the ring
rail A, in consequence whereof the portion of thread, running from the drawing
frame s s through the guide thread to the traveller, must always be of invariable
length.
The spindle a, which is supported and rotated in the usual manner, has a tube or
sleeve 6 slid upon it; a screw c, screwed into the side of the said tube b and projecting
into a longitudinal groove a¹ of the spindle a causes the tube b to rotate with the
spindle a, leaving it at the same time free to move endwise on the said spindle. By
means of its shoulder 6, the tube b rests on the bobbin-rail B and below this rail, a
nut 63 is screwed to the lower end of the tube b; this nut 62 is not wholly screwed
down so as to bind the tube b to the bobbin-rail B, but there remains a certain
clearance, which enables the tube 6 to turn freely within the hole of the bobbin-rail.
In consequence of the described arrangement, the tube b will, when the bobbin
rail B is reciprocated up and down by obvious means, be moved up and down along
the spindle a, while it will partake at the same time of the rotary movement of the said
spindle.
The tube is provided with a collar d upon which rests the lower flange g¹ of the
bobbing the collar d carrying a stud and the lower surface of the flange g¹ being
provided with one or more corresponding recesses, into one of which, the said stud d¹
will soon take, when the bobbin g is slid upon the upper end of the tube b and allowed
to drop down under the action of its own weight.
I am aware it has been heretofore proposed to construct ring spinning frames with
stationary rings and reciprocating bobbins, wherefore this construction is not now
claimed broadly; but in the constructions before proposed the spindle itself was made
to reciprocate by means of its bolster rail whilst in the construction hereinbefore
described, a sleeve is provided, movable endwise on the stationary live spindle and

page_text: supported by the reciprocated bobbin rail, this sleeve carrying the bobbin, and it is
obvious that this latter novel construction is by far simpler and cheaper.
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 :-
1st. In a ring spinning frame, the combination with a stationary ring of a tube or
sleeve, movable endwise on and rotating with the stationary spindle, a reciprocating
bobbin rail supporting the said tube, and a bobbin fixed to the tube, substantially as
and for the purpose set forth.
2nd. In a ring spinning frame, the combination with a stationary ring of a tube or
sleeve, movable endwise on and rotating with the stationary spindle, a reciprocating
bobbin rail supporting the said tube, a collar formed on the tube and having an
upward projecting stud, and a bobbin, slid on the said tube or sleeve and having in
its lower flange recesses corresponding to the said stud, substantially as and for the
purpose described.
