Improvements in Braiding Machines.
I, RICHARD MANN, Junior, of Barmen, Rhenish Prussia, Germany, Manufac-
turer, 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
My invention relates to an improved braiding machine and it has for its object
to produce laces, tresses or braids and cords in which two different sets of threads
are interwoven or interlaced with each other so that the thickness of the fabric
is doubled, whereas in an ordinary braiding machine working with the same
in
of the fabric would be increased
number of bobbins the width
This new result, of increas-
accordance with the number of bobbins.
ing the thickness instead of increasing the width of the fabric, or
other words of producing with a certain number of bobbins a braid corre-
sponding in width only to a braid made of half that number of bobbins in a
machine of ordinary construction, but having double the thickness of such an
ordinary braid, I attain by a new arrangement of the disks and by causing the
bobbins to march in a special way arround and along these disks and by arranging
the slotted curves, prescribing the way to the bobbins, in a new manner, as will
be described hereafter and shown by the accompanying drawing in which
Fig. 1 shows the arrangement of the new machine in plan;
Fig. 2 is a vertical cross section through the center of the machine;
Fig. 3 gives a diagram of the fabric produced.
My new machine consists of two sets of disks placed either parallel to each
other or, for practical reasons, by preference, placed concentric to each other,
and I use two separate systems of bobbins moving about to and fro on these two
sets of disks, but in such a manner, that the bobbins of one set move in opposite
direction to that of the other set, while at the same time they pass from one set
of disks over to the other set, continuously changing their places and thereby
crossing each other, and the threads drawn off from them therefore interlacing
with each other. This will explain how it happens, that the width of the braid
produced, though there is the double number of bobbins working as in a machine
of ordinary design, corresponds only to the width of a braid made of half the
- number of threads, but that the thickness of the braid is double of that of an
ordinary braid.
A glance at Fig. 1 of the drawing shows that there is a set of disks A, A1, A²
A 14, A 15 forming the inner circle or inner set, which is surrounded by
B 14, B 15. As in ordinary braiding
the equal number of disks B, B¹, B².
machines there is below each disk A, A¹ of course a notched, wheel every one of
which gearing with its neighbour right and left, except the end wheels (when
notched wheels
flat braids are to be produced) and below each disk B, B¹
) are similarly arranged.
Besides this all the corresponding wheels of the
disks A, B; A¹, BI; A2, B2 are in gear with each other, and the disks are
surrounded by the curved slots, which intercommunicate with each other. The
free spaces between every four disks are filled out by the pieces showing the

page_text: forms of a spherical quadrangle, and which are held in place by pillar bolts in
the well known manner, so that the curves have a continuous border throughout,
except where they intersect each other.
When the machine is set in motion indicated by the arrows near the disks A
and B, one system of bobbins marches in the direction and in the curves indi-
cated by the Figures 1, 2, 3 12, 13, where the bobbins begin their return
way in the direction 13, 14, 15
marches in a similar main direction
II, III. ... XII, XIII as far as
return in the curve XIV, XV.
23, 24, 25. The other system of bobbins
but in the curves indicated by the Figures I,
the end disk A 15, where they also begin their
XXIII, XXIV, XXV.
From this it will be seen that the bobbins of each set cross each other in
moving backwards and forwards in their own curves, but also, that the bobbins
of one system cross those of the other system both, in coming and in going.
Thus we see that the bobbin 1 on its march in the direction like the hands of
a clock will cross with the bobbin 23 of the same system marching in the opposite
direction, when both have moved forwards until they have reached the disk A',
on which disk in the position shown, the bobbins 2 and 24 are going past each
other. The bobbin 1 however on its way crosses also with the bobbin I of the
other system, which moves also in the direction of the hands of a clock, but of
course in its own curve; this crossing takes place when the bobbin 1 passes over
from the disk, B¹ to the disk A¹ and when the bobbin I goes over from the disk A¹
to the disk B¹.
Crossings corresponding to those of 2 and 24 or 1 and 23 and II and XXIV or
1 and XXIII take place respectively upon the disk B₁ and when the respective
bobbins are going over from B2 to B¹ and B¹ to B² respectively and so on, con-
tinuously changing in regular order.
From this peculiar manner of communication and intercommunication of the
two systems of bobbins it will be understood, that the threads carried by the
bobbins, and which are collected above the machine as usual in the braiding
iron, are interlaced with each other in a double manner and a fabric is produced
shown by the diagram in Figure 3, where the threads are marked with the same
ciphers as the bobbins 1, 2, 3 24, 25 and I, II, III
XXIV, XXV
for one complete journey of each bobbin, that is until it has received again its
starting point.
The machine shown in Fig. 1 in full drawn lines is for making flat braids and
therefore the notched disks at both ends, A B and A 15, B 15 of course must have
the corresponding larger number of notches or wings than those in the middle.
These having in the example shown 5 wings and 7 respectively and the end
disks 7 and 9. This is necessary, as is well known to ensure the proper exchange
in the positions of the bobbins, so that they can go past each other at the crossing
points and that not two crossing bobbins meet at the same point and run against
each other.
Now it will only require a slight change in the machine to produce round cord
of my new system of double interlaced threads. This is indicated in dotted lines
in Figure 1. In place of the end disks A, B and A 15, B 15 I place the four
disks b 15, 16, b 17, b 18 and a 15, a 16, a 17, a 18 respectively, so that the circles
will be closed, and it will then be understood that the bobbins will continue their
zig zag circular march and will produce a round cord or hose as ordinary cord
braiding machines, but of course with the difference due to the new system of
working, i.e. the double interlacing of the two systems of bobbins or threads.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
-
An improved braiding machine for making double interlaced flat braids or
double interlaced round cords or hose distinguished by two systems of disks placed
parallel or concentric to each other and having two separate systems of bobbins

page_text: working thereon in curves which are so arranged round the disks and in such
communication with each other that the bobbins of each system can pass over
from one set of disks to the other in regular alternation and that they can cross
each other as in an ordinary braiding machine on their march to and fro in their
respective curves, and that at the same time the bobbins of the two different
systems, which move in the same general direction (both like the hands of a
clock, or vice versa) can also cross each other, and that finally the bobbins of one
system moving in one direction can cross with those of the other system moving
in opposite direction, the whole as described and illustrated and for the purpose
set forth.
