respectively Patent Agents (a communication from abroad by the firm of
F. J. Grün of Lure, Haute-Saône in the Republic of France and of Guebwiller
Alsace-Lorraine in the Empire of Germany, Machinists) do hereby declare the
nature of this invention to be as follows:-
The invention has as its object the provision of a means of producing on ring-
frames used in spinning a soft yarn or thread for weaving into any textile fabric
whatever, which shall have at least as little twist as that produced on self-acting
mules and that with a greater production.
It consists essentially in placing near the top of the spindle a fixed piece, or
guide, which can be regulated, and which causes the thread of yarn at each
revolution to come in contact with the extremity of the spindle, or of a wooden
bobbin or carrier fitted to it, the thread thus has a motion communicated to it which
assists its rotation round the spindle and as a consequence, its winding up.
It also allows the soft yarn to be obtained and wound up on the base spindle or
on the spindle furnished with a paper-tube, and when it is applied to the manufacture
of ordinary yarn or to the twisting of threads it avoids the frequent breakages
which occur in the use of ring frames.
In the arrangement to be described the spindle carries a paper tube on which the
yarn is to be wound, and whose length should be such that the spindle projects
about to of an inch beyond the end of the tube.
To carry out the invention, a guide, made, for instance from steel wire bent at right
angles is held so that it can be adjusted in a fixed support fitted preferably to the
thread board, which extends the whole length of the frame and which carries the
joints of the laths on which are fixed the thread-guides which the thread of yarn
coming from the drawing rollers passes through on its way to the traveller, and is
at length wound up on the spindle-tube.
The position of this guide which forms the basis of the invention is. regulated in
such a way that its bent part is placed horizontally near the top of the spindle and
at a very slight distance from the spindle the distance being always enough to allow
the passage of the thread of yarn.
It is easy to see that at each revolution of the spindle, the thread or yarn which
it carries in its rotatory motion comes in contact with the guide, which causes it to
approach the top of the spindle so that the balloon formed by the centrifugal force
acting upon the thread; instead of being symmetrical with regard to the axis of the
spindle then takes an asymmetrical form.
Under these conditions the action of the frame is considerably modified; in effect
the total length of the balloon produced between the traveller and the upper thread-
guide, is on one side reduced to the distance between the traveller and the
horizontal guide above mentioned, and moreover the thread coming in contact
with the top of the spindle which is revolving at a high speed, receives from it a
slight rotatory motion.
It is also to be noted that the balloon, being at each revolution reduced in length
at the instant at which the thread passes between the guide and the spindle
forms a corresponding looseness which assists the winding up on the paper tube or
spindle.
This appliance avoids all the inconveniences which arise from winding in ring-
frames; in short on the one hand in these machines the traction of the thread is

page_text: considerable and occasions frequent breakages on account of the great distance left
between the rollers, the travellers and the point of winding upon the spindle, whilst
in this system this distance is divided into two parts by the application of the
guide; and on the other hand the impulse communicated to the thread by the top
of the spindle reduces by so much the force exerted by tlie traveller upon the
thread in order to communicate the rapid rotary motion which it must have around
the spindle.
The principle of the invention being thus explained it is to be understood that
the arrangement just described as an example may be varied in many ways in the
applications which can be made of it, for instance the same result may be obtained
by placing the guide a little below the top of the spindle and allowing it to fit
partly into a slight groove cut at this height in the spindle or in the wooden bobbin
or carrier which can be taken away in order to put on the paper tube upon which
the thread is wound.
If it is desired vertical flutings can be made in the top of the spindle or of the
bobbin in which the thread would be caught at the moment of passing.
Or again the guide might also be placed above the top of the spindle in a line
with the axis of the spindle in such a way that the thread would always be obliged
to come in contact with it at each revolution of the spindle.
Again instead of bending the guide into a straight line it might be given if so
desired, a slightly curved form with its concavity turned towards the axis of the
spindle the essential point in each case being that the thread be brought at each
revolution towards the top of the spindle so as to receive a slight impulse which
facilitates its rotatory motion around the spindle.
It is considered that the new method of winding herein described and applic-
able to all ring frames, allows of the production on these frames of a thread
of yarn as soft, that is to say with as little twist as is desired, and' of the winding
of it upon the spindle itself or on the spindle furnished with a paper tube without
recourse to the bobbin of wood or other material which are generally used.

Improvements in Ring Spinning Frames.
I, JOHN OWDEN O'BRIEN, M.I. Mech. E. of the firm of W. P. Thompson & Co.,
of Manchester, Liverpool, and London, in the Counties of Lancaster and Middlesex
respectively Patent Agents (a communication from abroad by the firm of
F. J. Grün of Lure, Haute Saône, in the Republic of France and of Guebwiller,
Alsace Lorraine, in the Empire of Germany, Machinists 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 :-
The invention has as its object the provision of means for producing on ring-
frames used in spinning a soft yarn or thread for weaving into any textile fabric
whatever, which shall have at least as little twist as that produced on self-acting
mules and that with a greater production.
It consists essentially in placing near the top of the spindle an adjustable piece
or guide which causes the thread of yarn at each revolution to come in contact
with the extremity of the spindle, or of a wooden bobbin or carrier fitted to it,
the thread thus has a motion communicated to it which assists its rotation round
the spindle, and, as a consequence, its winding up.
This guide thus enables the soft yarn to be obtained and wound up on the bare
spindle, or on the spindle furnished with a paper tube, and when it is applied
to the manufacture of ordinary yarn, or to the twisting of threads, it obviates the
frequent breakages which occur in the use of ring-frames.

page_text: Figure 1, represents as an example an elevation (partly in section) of the
invention applied to one spindle of a spinning frame.
Figure 2, plan of the appliance.
Figure 3, elevation of a modification of same.
Figure 4, plan of Figure 3.
In the example represented in the drawings Figures 1 and 2 the spindle A carries
a paper tube on which the yarn is to be wound, and the length of which should
be such that the spindle projects about to of an inch beyond the end of the
tube.
To carry out the invention, a guide, G, made for instance from steel wire bent
at right angles, is adjustably arranged in a fixed support D, fitted preferably to
the thread board E which extends the whole length of the frame, and which
carries the joints of the laths on which are fixed the thread guides F, which the
thread of yarn coming from the drawing rollers C passes through on its way to the
traveller H, and is at length wound up on the spindle tube.
The position of this guide which forms the basis of the invention is regulated in
such a way that its bent part G is placed horizontally near the top of the spindle A
and at a very slight distance from the spindle, the distance being always enough to
allow of the passage of the yarn.
It is easy to see that at each revolution of the spindle the thread or yarn which
it carries with it in its rotary motion, comes in contact with the guide G, which
causes it to approach the top of the spindle so that the balloon formed by the
centrifugal force acting upon the thread, instead of being symmetrical with regard
to the axis of the spindle then takes an asymmetrical form as represented at B
and B' Fig. 1.
Under these conditions the action of the frame is considerably modified; in fact
the total length of the balloon produced between the traveller and the upper
thread-guide, F, is on one side reduced to the distance between the traveller, and
the horizontal guide G. above mentioned, and, moreover, the thread coming in
contact with the top of the spindle which is revolving at a high speed, receives
from it a slight rotary motion.
It is also to be noted that the balloon, being at each revolution reduced in length
at the instant at which the thread passes between the guide and the spindle there
is produced a corresponding looseness which assists the winding up on the paper
tube or spindle.
This appliance obviates all the inconveniences which arise from winding in ring-
frames; in short, on the one hand in these machines the tension of the thread is
considerable, and occasions frequent breakages on account of the great distance left
between the rollers, the travellers, and the point of winding upon the spindle,
whilst in this system this distance is divided into two parts by the application of
the guide G; and on the other hand, the impulse communicated to the thread by
the top of the spindle reduces by so much the strain exerted by the traveller
upon the thread in order to give it the rapid rotary motion, which it must have,
around the spindle.
The principle of the invention being thus explained, it is evident that the
arrangement just described as an example may be varied in many ways in its appli-
cation for instance, the same result. may be obtained by placing the guide Ga
little below the top of the spindle and allowing it to fit partially into a slight
groove cut at this point in the spindle or in the wooden bobbin or carrier which
may be placed there to receive the paper tube upon which the thread is to be
wound, one arrangement of this kind is shown in Figs. 3 and 4 of the drawings.
If desired vertical flutings may be made in the top of the spindle or of the bobbin
in which the thread would be caught at the moment of passing, one arrangement of
this kind is shown in Figs. 3 and 4.
Or again the guide G might also be placed above the top of the spindle in a

page_text: line with the axis of the same in such a way that the thread would always. be
obliged to come in contact with it at each revolution of the spindle.
Again instead of bending the guide, G, in a straight line, as shown on the
drawing it might be given, if so desired, a slightly-curved form, with its concavity
turned towards the axis of the spindle, the essential point in each case being, that
the thread be brought at each revolution towards the top of the spindle so as to
receive a slight impulse which facilitates its rotary motion around the spindle.
It will be understood then that the new method of winding herein described,.
and applicable to all ring frames, allows of the production on these frames of a
thread of yarn as soft, that is to say with as little twist, as is desired and of the
winding of it upon the spindle itself, or on the spindle furnished with a paper tube
without having recourse to the bobbins of wood or other material which are generally
used.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that, what I
claim is :-
1. In ring spinning frames used to spin or twist yarns of textile materials an
adjustable guide rod fixed transversely near the top of the spindle in such a manner
that the balloon of yarn may come in contact with it, and be brought at each
revolution in contact with the top of the said spindle or with the bobbin fitted upon
it, substantially as described.
2. In ring spinning frames the combination with a spindle carrying a groove
near its upper extremity, or fitted with a bobbin also carrying a groove of an
adjustable and removable guide rod fixed transversely to the spindle and in such a
way as to fit partially into the groove without touching the sides, substantially for
the purpose and in the manner described.
