page_text: We, BERNHARD KIRSCH, of XVIII, Sternwaitstrasse 50, Vienna, Austria,
Imperial and Royal Professor, and ADOLF PLSSL, of I, Rathhausstiasse 8,
Vienna aforesaid, Merchant, do hereby declare the nature of this invention
to be as follows:-
A machine according to this invention 18 specially adapted for covering ropes,
coids, or cables with biaid to form an outer covering therefol.
Such a braiding machine differs from the hitherto usual vertical braiding
machines by having a horizontal axis, and 18 characterized by the fact that the
bobbins coresponding to one group of braiding-stips are moved alternately
to and fio on the spindles (which are located opposite to one another) of two
discs of spiders (hereinafter called "spiders") which 10tate in the same duec-
tion and at the same speed, so that the said bobbins travel along a wavy line on the
cylindrical surface described by the spindles, whilst the other group of braiding-
strips rotates between, and in a direction opposite to that of. the two spiders
so that from the two groups of threads of the braiding-strips there is formed
a braid that surrounds the iope or cable, which moves continuously through the
hollow pivots of the spiders and a cential bush.
Each braiding stip consists of a number of yarn threads, which must lie
parallel to one another in the braid, so that they form what may be described
as a flat band whose thickness does not exceed that of the single yarn. In
order to attain this result, there are arranged, as near as possible to the bush
that serves to compress the finished braiding thread-guides which join in the
1otary movement of the braiding-strips and prevent the yarn threads of each
strip from crossing one another and thereby causing the braided 1ope to be
Jammed in the bush
For those braiding-stips whose bobbins are alternately moved over from the
spindles of one spider to those of the other and which therefore travel in a
wavy path, these thread-guides consist of inwardly opening forks, which have
a notch for each thread. These forks are located opposite to one another at a
certain distance apart, so that the threads of the braiding-stips rotating D
the cential plane can pass between them, and they approach each other only
for a short time, during the transfer of the bobbins, for the purpose of insuring
the transfer of the bobbins of the braiding-strips from the right hand forks to
the left-hand forks or vice versa.
The transfer of the bobbins from one spider to the opposite one is caused by
Oscillating levers, and the bobbins are held in their position for the time being,

page_text: against the pull of the braiding-strips, by spring pawls, which are released
as soon as the levers are set in motion.
The accompanying drawings illustrate an example of such a braiding-machine
in which eight braiding-stips are used.
Fig 1 shows a vertical section of the machine, symmetrical portions being
shown only once and the horizontally arranged transmission shafts appealing
turned up into the vertical plane.

the sake of clearness certain parts are omitted.

The parts a and b are two igidly fixed heads which are located opposite
to each other and are turned cylindrical at then inner ends and which form
the pivots for the rotating spiders (. One head a has at its inner end a cavity
for the bush, which serves to compress the braiding, whilst both heads are
bored out for the passage of the rope or cable e.

The spiders c, each of which carries four spindles f of square cross section,
ale rotated at the same speed and in the same direction by means of bevel-
wheels g, which are mounted on then hubs and which engage the bevel-wheels h
of the shafts so that the spindles f of the one spider are always located opposite
to those of the other spider The four bobbins on which the threads of the
braiding-strips of the one group are wound, can therefore be moved, during
theu rotation around the axis of the machine, from the night-hand spindles f
to the left-hand ones and rue versa Each bobbin 18 rotatably mounted on
a sleeve 7, which fits the square spindle f and 18 rigidly fixed to a fiame m that
carries a tension-device not shown in the drawings The bobbins are moved
fiom spindle to spindle by single-aim leveis n, which are pivoted at o on the
hubs of the spideia and embrace the spindles f with then forked ends and
which are oscillated by means of sliding rods p that engage the curved grooves
of discs g Each disc 18 loosely mounted on the hub of the corresponding
1
spider and is driven at the same speed as the spiders c but in the duection
opposite to that of the spiders, by a bevel-wheel of a hollow shafts that
surrounds the corresponding shaft On each of the discs g there are fixed
four aims on which are mounted spindles which are circular in cross section
and are adapted to canly the bobbins . that contain the yain threads that
form the four braiding strips w of the second group In the present case the
vain of each braiding-strip to is distributed on two bobbins ", which can there-
fote be much smaller than the bobbins while containing the same length of
\arn From the bobbins the yarn passes over the ends (which are bent
inwardly and screwed together) of the aims t and join together to form a biaid-
ing-strip in each of the four radial sheath-like thread guides which are
attached to the arms and carry at their inuer ends perforated thread-guide
plates y
The theads of the braiding-stips k proceeding from the bobbins 7 are led,
neat to the bush d, through thread-guide forks 1 (Figs 5 and 6) which are
tuned with their openings inwards, the openings or notches of each fork 1
are tuined towards those of the fork 1 opposite to it These forks are mounted
on stems 3 which carry square bosses 2 and are horizontally movable in sup-
ports 4hxed to the spiders c, whilst by then inwardly bent inner ends they
engage in curved grooves 5 of 1ings 6 which are fixed igidly to heads and b
iespectively.

page_text: In order to prevent the bobbins 1 from being drawn inwards by the tension
of the braiding-strips proceeding towards the bush d, there is mounted on
each lever na spring pawl 7, which, as soon as the bobbin arrives from the opposite
side, snaps in behind the projection 8 of the bobbin frame m and thereby holds
the bobbin fast This pawl is disengaged when the lever n begins to push the
bobbin inwards.
The driving of the machine is effected by the main driving shafting 9, which
carries at each end a bevel-wheel 10 that forms a reversing motion in combination
with a bevel-wheel 11 fixed on the shaft i and a bevel-wheel 12 keyed on the
hollow shaft s The shafts and therefore rotate in opposite directions but at
the same speed.

For the purpose of facilitating the changing of the bobbins 7, there are inserted
in the main driving shafting 9 a claw coupling 13, so that when the said
coupling is disengaged each of the spiders c can be turned independently and
can therefore be brought into the most convenient position for taking off and
putting on the bobbins
When working, the bobbins are carried in a cucle around the rope e to be
braided and are, at the same time, pushed across by the lever n, alternately
towards the one side and the other The braiding-strips A, which must follow
the movement of the bobbins, travel along the wavy line shown in Fig 3, whilst
the braiding-stips to more continuously in the central plane of the machine
In this manner there is formed in the present case an eight-stranded braid
in which each strip of the one group crosses each stup of the second group

disc q and which set the levers n in motion by means of the sliding rods p In
each disc there are two sliding rods which are located on lines radiating at an
angle of 180° from each other and engage in the groove indicated by full lines,
which is arranged in the flange of the disc itself, and also two other sliding
rods, which are likwise located on lines radiating at an angle of 180° from
each other but engage in the groove indicated by bioken lines, which is located
on the inner surface of a bipartite ng 14 screwed to the disc Each lever n
pushes the bobbin located in front of it, upon the spindle f of the opposite
spider and thereupon returns at once to its normal position, so that it avoids
the thread-guide sheaths . which pass between the ends of the spindles f.
The perforated thread-guide plates y hold the several threads of the stips in
beside one another and the threads of each braiding-strip are led through the
notches of the thread-guide forks 1, which follow the movement of the braiding-
stups In Fig 8 there is shown a development of the curved grooves 5 of the
abutment collais 6, in which the outer ends of the fork stems 3 engage.
As soon as a bobbin is pushed over the fork 1 guiding the corresponding
branding-strip, and the fork located opposite to it, move inwardly towards each
other so that these forks almost touch while the threads are being transferred
from the one fork into the other Thereupon the two forks separate again in
order to provide 100m for the passage of the braiding-stup so that while the
one fork is empty, the other holds the braiding-strip, which, by reason of its
tension, les close in the notches of the fork
A braiding machine of the kind described possesses the advantage that the
1ope or cable to be braided can be drawn through the braiding machine and be
braided in a houzontal direction while maintaining the tension at which it
comes out of the 1ope-spinning apparatus Braiding machines according to this
invention can, of course, be constructed for braidings with a different number of
strips from that of the machine herein before described

We, BERNHARD KIRSCH, of XVIII, Steinwartsstrasse 50, Vienna, Austria,
Imperial and Royal Professor, and ADOLF PESSL, of I, Rathhausstrasse 8,
Vienna, aforesaid, 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
-
A braiding machine according to this invention is specially adapted for cover-
ing 1opes, cords, or cables with braid to form an outer covering therefor.
Such a braiding-machine differs from the hitherto usual vertical braiding-
machines by having a horizontal axis and 18 characterized by the fact that the
bobbins corresponding to one group of braiding-strips are moved alternately
to and fro on the spindles (which are located opposite to one another) of two
spiders which rotate in the same direction and at the same speed so that the said
bobbins travel along a wavy line on the cylindrical surface described by the
spindles, whilst the threads of the other group of braiding-strips rotates
between, and in direction opposite to that of, the two spiders so that from the
two groups of braiding-strips there is formed a braid that surrounds the rope or
cable, which moves continuously through the hollow pivots of the spiders and
through a central bush.
Each braiding-strip consists of a number of yarn-threads which must lie
parallel to one another in the braid so that they form what may be described
as a flat band whose thickness does not exceed that of a single yarn thread. In
order to attain this result, there are arranged, as near as possible to the bush
that serves to compress the finished braid, thread-guides which join in the rotary
movement of the braiding-strips and prevent the yain-threads of each strip
from crossing one another and thereby causing the braided rope to be jammed
in the bush.
For those braiding strips whose bobbins are alternately moved over from the
spindles of one spider to those of the other and which therefore travel in a
wavy path, these thread-guides consist of inwardly opening forks which have
a notch for each thread. The forks are located opposite to one another at a
certain distance apart so that the braiding-strips rotating in the central plane
can pass between them, and they approach each other only for a short time,
during the transfer of the bobbins, for the purpose of insuring the transfer of the
threads of the braiding strips from the night hand forks to the left-hand forks
or vice versa.
The transfer of the bobbins from one spider to the opposite one is caused
by oscillating levers and the bobbins are held in their position for the time
being, against the poll of the threads of the braiding-strips by spring catches
which are released as soon as the levers are set in motion.
The drawings filed with our Provisional Specification illustrate an example
of such a braiding-machine in which eight braiding-strips are used.
Fig. 1 shows a vertical section of the machine, symmetrical portions being
shown only once and the horizontally arranged transmission shafts appearing
turned up into the vertical plane

the sake of clearness certain parts are omitted.

The parts
a and b are two rigidly fixed heads which are located opposite to
each other and are turned cylindrical at their inner ends and which form the
pivots for the rotating spiders One head a has at its inne end a cavity for the
bush d which serves to compiess the braid, whilst both heads are bored out
for the passage of the rope or cable e
The spiders e, each of which carries four spindles f of square cross section,
are rotated at the same speed and in the same duection by means of bevel-
wheels 9, which are mounted on then hubs and which engage the bevel-wheels h
of the shafts so that the spindles f of the one spider are always located opposite
to those of the other spider The four bobbins on which the threads of the
braiding-stips of the one group are wound, can therefore be moved, during
then rotation around the axis of the machine, from the night-hand spindles /
to the left-hand ones and ce versa
Each bobbin 18 rotatably mounted on a sleeve / which fits the square spindles f
and 18 rigidly fixed to a frame m that cares a tension device not shown in
the diawings The bobbins are moved from spindle to spindle by single-arm
levers n, which are pivoted at o on the hubs of the spiders c, embrace the
spindles with their forked ends, and are oscillated by means of sliding rods p
that engage in the curved grooves of discs q.. Each disc 18 loosely mounted on
the hub of the corresponding spider e and is driven at the same speed as the
spiders but in the duection opposite to that of the spiders by a bevel-wheel r
of a hollow shafts that surrounds the corresponding shaft > On each of the
discs q there are fixed four arms on which are mounted spindles which are
circular in cross section and are adapted to carry the bobbins u that contain
the varn-threads that form the four braiding-strips of the second group.
In the present case the rain of each braiding-stip 18 distributed on two
bobbins, which can therefore be much smallei than the bobbins while con-
taining the same length of yain From the bobbins u the yarn threads pass over
the ends (which are bent inwardly and sciewed together) of the arms t and
Join together to form a braiding-stip in each of the four radial sheath-like
thread-guides which are attached to the arms and cauly at their inner ends
perforated thread-guide plates y
The threads of the braiding-strips k proceeding from the bobbins are led,
near to the bush d, through thread-guide forks 1 (Figs. 5 and 6), which are
turned so that then notches face inwards-e, the notches of each fork 1 are
turned towards those of the fork 1 opposite to it
These forks are mounted on
stems 3 which cairy square bosses 2 and are hon 17ontally movable in supports +
fixed to the spiders, whilst then inwardly bent inner ends they in curved
grooves 6 of rings 6 which are fixed igidly to the heads and b respectively
In order to prevent the bobbins 7 from being drawn inwards by the tension
of the braiding-strips proceeding towards the bush d, there is mounted on
each leve a sping catch 7, which, as soon as the bobbin aves from the
opposite side, snaps in behind the projection 8 of the bobbin-fiame m and thereby
holds the hobbin fast This catch is disengaged when the lever n begins to
push the bobbin, mwards.
The diving of the machine is effected by the main diving shafting 9 which
cairies at each end a bevel-wheel 10 that gears into a bevel-wheel 11 fixed
on the shaft and a similar bevel-wheel 12 keyed on the hollow shaft s
that the shafts and iotate in opposite directions but the same speed
For the purpose of facilitating the changing of the bobbins, there is inserted
into the main during shafting 9 a claw coupling 13, so that when the said
coupling 18 disengaged each of the spiders c can he turned independently and

page_text: can therefore be brought into the most convenient position for taking off and
putting on the bobbins J.
When working, the bobbins are carried in a cucle around the rope e to
be braided and are, at the same time, pushed across by the levers n, alternately
towards the one side and the other The braiding-stips k, which must follow
the movement of the bobbins, travel along the wavy line shown in Fig 3, whilst
the braiding-strips move continuously in the central plane of the machine
In this manner there is formed in the present case an eight-stranded braid in
which each stup of the one group crosses each strip of the second group

strips.
In Fig 8 there is shown a development of the curved grooves 5 of the abutment
collars 6, in which the outer ends of the fork stems 3 engage.
As soon as a bobbin is pushed over, the fork 1 guiding the threads of
the corresponding braiding-strip Z, and the fork located opposite to it move in-
wardly towards each other so that these forks almost touch while the threads
are being transferred from the one fork into the other Thereupon the two forks
separate again in order to provide room for the passage of the braiding-strips w.
so that while the one fork is empty, the other holds the threads of the braiding-
strip, which by reason of their tension, he close in the notches of the fork
Abiaiding-machine of the kind described possesses the advantage that the
hope or cable to be braided can be drawn through the braiding-machine and
be braided in a horizontal duection while maintaining the tension at which
it comes out of the 1ope-spinning apparatus Branding-machines according to
this invention can of course, be constructed for braiding with a different number
of strips from that of the example hetembefore described
Having now particularly described and ascertained the nature of the said
invention we declare that what we claim is.-
1. A braiding-machine in which the bobbins corresponding to one group of
braiding-strips are pushed to and fio on the spindles f, which are located opposite
to one another, of two spiders 1otating in the same duection and at the same
speed, whilst the threads of the braiding-stups of the other group rotate between
the two spiders o and in the direction opposite to that of the bobbins of the afore-
said group, while the rope or cable 18 moved continuously through the hollow
pivots of the spiders
