Improvements in and relating to Ring Spinning Machines.
I, ADOLF HARDMEYER of Gorice in the Empire of Austria, Director of
Spinning Mill, do hereby declare the nature of this invention to be as follows:-
In spinning on ring machines, a tension of the yarn takes place as soon as the cop
has reached about two thirds of its full size, which tension becomes greater and
greater until the bobbin is filled, and which produces numerous breakages of the
yarn. This tension of the yarn arises from the short distance between the thread
guide and ring rail.
By the use of a movable thread guide this distance is increased by means of a
corresponding upward motion of the thread guide and consequently the tension of
the yarn is lessened.
Referring to the drawings
An angle piece W is attached to the counter shaft T (from which the up and
down travelling motion of the thread guide is derived, as for instance by means of
the lever T), and preferably on the opposite side to the lever T. This angle
piece moves with the counter shaft, and commences, at a given adjustable moment,
at each lift of the ring rail, to fall, and thus to press upon the lever N, whereby
this latter turns downwards on its axle Z.
The lever N is connected with the rocking arm B by means of the connecting
rod E, so that by the fall of the rod E the outer end of the rocking arm B con-
nected therewith, moves in a downward direction, rotating on the pivot D. A
second branch G of the rocking arm makes thereby a movement (to the left) and in
connection with the levers H, J, K, M, N, lifts the thread board L, which motion
it is self evident all the thread guides F must follow.
When the ring rail again descends, the angle piece W releases the lever N, and
the thread guides return to their original position.
These successive up and down movements of the thread guides continue until the
cops are completed. The thread-board L is connected to the roller beam by the
hinge X, the cheeks of which respectively engage the roller beam and the thread
board by means of the screws S¹ and s. These hinges have their axles above the
thread guides F, so that these latter are enabled to describe a larger course upwards
without thereby coming, in their vertical position, essentially out of the centre of
the spindle.
The apparatus is thus so regulated that as soon as say of the bobbin is filled,
that is to say as soon as the tension of the thread commences to set in the angle
piece W comes in contact with the lever N. From this point to the completion of
the cop on each lift of the ring rail the thread guide rises also, so that the distance
between thread guide and spindle point is not reduced as would be the case where
this arrangement is not employed.

SPECIFICATION.
Improvements in and relating to Ring Spinning Machines.
1, ADOLF HARDMEYER, of Gorice, in. the Empire of Austria, Director of
Spinning Mill, 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::-
In spinning on ring machines, a tension of the yarn takes place as soon as the cop
has reached about two thirds of its full size, which tension becomes greater and
greater until the bobbin is filled, and which produces numerous breakages of the
yarn. This tension of the yarn arises from the short distance between the thread
guide and ring rail.
By the use of this improved movable thread guide, this distance is increased by
means of a corresponding upward motion of the thread guide and consequently the
tension of the yarn is lessened.
Reference being had to the drawings filed with the Provisional Specification and
to the figures and letters of reference marked thereon, in which,
Figure 1 is a side view, and
Figure 2 is a corresponding front view of the jointed thread board with the
mechanism for elevating such at a given moment.
Figure 3 is a view of a detail of the same.
An angle piece W is attached to the counter shaft T (from which the up and
down travelling motion of the ring rail is derived, as, for instance, by means of the
lever To) and preferably on the opposite side to the lever T. This angle piece
moves with the counter shaft and commences, at a given adjustable moment, at
each lift of the ring rail to fall, and thus to press upon the lever N, whereby this
latter turns downwards on its axle Z.
The lever N is connected with the rocking arm B by means of the connecting rod E,
so that, by the fall of the rod E, the outer end of the rocking arm B, connected
therewith, moves in a downward direction rotating on the pivot D. A second
branch of the rocking arm makes thereby a movement (to the left) and in con-
nection with the levers H, I, K, M, N', lifts the thread board or boards L, which
motion, it is self evident, all the thread guides F must follow.
When the ring rail again descends, the angle piece W relcases the lever N, and
the thread guides return to their original position.
These successive up and down movements of the thread guides continue until the
cops are completed. The thread board L is connected to the roller beam by the
hinge X, the checks of which respectively engage the roller beam and the thread
board by means of the screws S¹ and s. These hinges have their axles above the
thread guides F, so that these latter are enabled to describe a larger course
upwards without thereby coming, in their vertical position, essentially out of the
centre of the spindle.
The apparatus is thus so regulated that, as soon as say of the bobbin is filled,
that is to say, as soon as the tension of the thread commences to set in, the angle
piece W comes in contact with the lever N. From this point to the completion of
the cop on each lift of the ring rail, the thread guide rises also, so that the distance
between thread guide and spindle point is not reduced as would be the case where this
arrangement is not employed, but on the contrary is gradually increased.
When the above described arrangement is made use of, cops of a larger size can
be formed without having to employ, behind the spindles, mechanism which would
hinder the working power of the machine.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is:
1. The improved arrangement hereinbefore described for use in ring spinning

page_text: machines, whereby the tension which is produced in the yarn towards the end of
the filling of the bobbins is removed by a successive upward motion being com-
municated from a given moment to the thread guides F, simultaneously with the
lifting of the ring rail.
2. In ring spinning machines, a thread guide board fixed on the roller beam and
movable upwards in such a way that the pivot X of the same stands above the
thread guides when they are in a normal position.
3. The arrangement and combination of parts substantially as herein before
described and shown, forming the improved movable thread guide for use in ring
spinning machines.
