PROVISIONAL SPECIFICATION.
Improvements in Machinery or Apparatus for Making Ropes.
I, ADOLF PESSL, of II Kleine Sperlgasse 8, Vienna, Austria, Merchant, do
hereby declare the nature of this invention to be as follows:-
This invention relates to apparatus for making round ropes composed of co-axial
layers of textile threads twisted in alternately opposite directions.
The rope is made, according to this invention, by means of a series of discs or
arms arranged one behind the other to have a common axis and carrying the thread
reels or bobbins, the arrangement being that the first disc makes the core, and the
following discs make the several concentric layers of threads, whilst a drawing
apparatus or winch slowly draws the finished rope from the apparatus and coils
it up.
The discs or arms, together with the reels mounted thereon, rotate in opposite
directions, and have centrally inserted bushes of steel or other suitable hard
material through which the rope passes, a fresh layer of threads being applied in
front of each bush. In its passage through the bushes, the rope is compressed and
smoothed or polished.
Apparatus constructed according to this invention is illustrated in the accom-
panying drawings, in which
Fig. 1 is a broken side elevation representing an entire plant, and
Figs. 2 and 3 are respectively a front and a side elevation, both partly in section,
of one construction of reel-disc and its appurtenances, whilst Figs. 4 and 5 are
similar views of a modification thereof.
As shown in Fig. 1, the reel-carrying dises A, A1, A3, A3 etc. are arranged to
have a common axis of rotation, and are adapted to be rotated from suitable
shafting B in alternately opposite directions, whilst the drawing apparatus C,
which is preferably constructed as a friction-winch, slowly draws the rope away,
and delivers it up again without twist, so that the rope can be wound-up on a
windlass-barrel.
The thread-reels a may be mounted upon studs a¹ which are arranged parallel
to the axis of the discs, as shown in Figs. 2 and 3; or they may be mounted upon
spindles as which are arranged perpendicularly to the axis of the discs and are held
at both ends in bearings b, as shewn in Figs. 4 and 5.
The number of reels upon the several discs corresponds to the number of threads
in the co-axial layers formed by them. The threads c passing from the reels are
guided towards the axis, according to requirements, by means of thread-guides c¹
(preferably open double hooks) and guiding eyes c².
Each disc is mounted with its hub d on a hollow axle d' supported in bearings d³,
and is formed, for the reception of the bush e, which may be made of steel or other
suitable hard material, with a bell-shaped part e¹, which is provided with openings e
for the insertion of the bush e, and rests with its hollow extension e³ in a bearing et.

page_text: The bush e, which is arranged to share the rotary motion of the disc, is made
with a slightly conical bore for the purpose of pressing the threads entering it
firmly against the portion of the rope that is already formed, and also of smoothing
the said threads.
The pitch of the helical lines formed by the several threads is dependent on the
ratio of the speed of rotation of the disc to the speed of draw or travel of the
rope. Now since the latter speed is constant for all the reel-discs, then if all
the layers of threads are to possess the same pitch, the numbers of revolutions of
the successive discs may decrease in inverse proportion to the number of threads
supplied by them.
It is obvious that the discs may not only be driven by means of alternately open
and crossed belts, as indicated in Fig. 1, but they may also be driven by means of
toothed or chain gearing or of any other suitable mechanism. Also, the reels may
be arranged on one side only of the disc, instead of on both sides as shown in
Fig. 3, without departing from the nature of this invention.
The entire plant may be employed for making ropes of different thicknesses,
the number of discs charged with reels varying with the thickness of rope it is
desired to produce.

Improvements in Machinery or Apparatus for Making Ropes.
I, ADOLF PESSL, of II Kleine Sperlgasse 8, Vienna, Austria, Merchant, 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 apparatus for making round ropes composed of con-
centric layers of textile threads twisted in alternately opposite directions.
The rope is made, according to this invention, by means of a series of discs
or arms arranged one behind the other to have a common axis and carrying the
thread reels or bobbins, the arrangement being such that the first disc makes the
core, and the following discs make the several concentric layers of threads, whilst
a drawing apparatus or winch slowly draws the finished rope from the apparatus
and coils it up.
The discs or arms, together with the reels mounted thereon, rotate in alternately
opposite directions, and have centrally inserted bushes of steel or other suitable
hard material through which the rope passes, a fresh layer of threads being applied
in front of each bush. In its passage through the bushes, the rope is compressed
and smoothed or polished.
Apparatus constructed according to this invention is illustrated in the drawings
filed with my Provisional Specification in which,
Fig. 1 is a broken side elevation representing an entire plant;
Figs. 2 & 3 are respectively a front and side elevation, both partly in section,
showing, to a larger scale than Fig. 1, one construction of reel-disc and its appur-
tenances; and
Figs. 4 & 5 are similar views to Figs. 2 and 3 respectively, showing a modified
.construction thereof.

page_text: As shown in Fig. 1, the reel-carrying discs A, A1, A2, A3, etc., are arranged to
have a common axis of rotation, and are adapted to be rotated from suitable
shafting B in alternately opposite directions, whilst the drawing apparatus C,
which is preferably constructed as a friction-winch, slowly draws the rope away,
and delivers it up again without twist, so that it can be wound-up on a windlass-
barrel.
The thread-reels a may be mounted upon studs a¹ which are arranged parallel
to the axis of the discs, as shewn in Figs. 2 & 3; or they may be mounted upon
spindles a³ which are arranged perpendicularly to the axis of the discs and are
held at both ends in bearings b, as shown in Figs. 4 and 5.
The number of reels upon the several discs corresponds to the number of threads
in the concentric layers formed by them. The threads c passing from the reels
are guided towards the axis, according to requirements, by means of thread-
guides c¹ (Fig. 2) (preferably open double hooks) and guiding eyes c³. For the
sake of clearness the thread-guides e¹ are omitted from Fig. 3.
Each disc is mounted with its hub d on a hollow axle di supported in a bear-
ing, and is formed, for the reception of the bush e (which may be made of steel
or other suitable hard material), with a bell-shaped part e¹, which is provided with
openings e for the insertion of the said bush, and rests with its hollow exten-
sion in a bearing et.
The bush e, which is arranged in such a manner that it shares the rotary motion
of the disc, is made with a slightly conical bore for the purpose of pressing the
threads entering it firmly against the portion of the rope that is already formed,
and also of smoothing the said threads.
The pitch of the helical lines formed by the several threads, is dependent on the
ratio of the speed of rotation of the disc to the speed of draw or travel of the rope.
Now since the latter speed is constant for all the reel-discs, then if all the layers of
threads are to possess the same pitch, the numbers of revolutions of the successive
discs must decrease in inverse proportion to the number of threads supplied by
them.
It is obvious that the discs may not only be driven by means of alternately open
and crossed belts, as indicated in Fig. 1, but they may also be driven by means of
toothed or chain gearing, or of any other suitable mechanism. Also, the reels
may be arranged on one side only of the disc, as shown in Figs. 4 & 5, instead of
on both sides, as shown in Fig. 3, without departing from the nature of this
invention.
The entire plant may be employed for making ropes of different diameters, the
number of discs charged with reels varying with the diameter of rope it is desired
to produce.
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. Machinery or apparatus for the manufacture of round ropes composed of con-
centric layers of threads comprising a series of discs or arms A, A1, A2, A3, which
rotate in opposite directions, are arranged one behind the other, and carry
thread-bobbins a, the arrangement being such that the bobbins on the first disc or
spoked frame supply the threads to form the core, and those on each succeeding
disc or spoked frame supply the threads to form a concentric thread-layer of the
rope, the arrangement of the revolving discs A, A1, A2, A³ carrying the thread-
bobbins a, being such that the threads delivered from the bobbins a of each disc or
spoked frame are led to a bush e which is fixed centrally to the said disc or spoked
frame, and which lays the corresponding layer of threads upon the completed
portion of the rope and also compresses and smooths the same, substantially as
hereinbefore described.
2. For making ropes composed of concentric layers of threads, machinery or
apparatus constructed, arranged and operating as herein before described with

page_text: reference to and shown in Figs. 1, 2, and 3, and the modification thereof as herein-
before described with reference to and shown in Figs. 4 and 5, of the drawings.
herein referred to.
Dated this 21st day of November 1895.
