PROVISIONAL SPECIFICATION.
Improvements in Bobbins for Braiding Machines.
I, OTTO SEYDLITZ, of Barmen, Bismarkstrasse, Rhenish Prussia, Germany,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved bobbin for use in braiding machines, and
it has for its object to avoid the winding of the yarn from the spools of the
spinning machines on separate bobbins for the use with the braiding machine
and to make the new bobbin fit that it can be provided with the yarn direct on
the spinning machine and so be ready for use with the braiding machine.
In order to answer this double purpose the bobbin is made without a rim at
both ends; at its lower end it is cut off quite straight and at its upper end it is
provided with the indentations of ordinary braiding machine bobbins. Its shape
is on the whole cylindric with a slightly concaved outline in an axial direction.
The accompanying drawing shows the new bobbin.
Fig. 1 is a longitudinal section of the same;
Fig. 2 shows it with the yarn wound upon it;
Fig. 3 shows its use in combination with a bobbin carrier of a braiding machine.
The bobbin consists of a hollow cylinder A of wood or other material slightly
thinner in the middle of its length than at the ends; its lower end B is cut quite
straight and its upper end C is provided with indentations D, so that when placed
upon a bobbin carrier E it will stand straight upon the breast F and allow the
pawl G to fall into the teeth and prevent its turning.

Improvements in Bobbins for Braiding Machines.
I, OTTO SEYDLITZ, of Barmen, Bismarkstrasse No. 82, Rhenish Prussia Germany,
Manufacturer, 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:-
My invention relates to an improved bobbin for use in braiding machines and it
has for its object to make the new bobbin fit to be provided with the yarn direct
on the spinning machine so as to be ready for use with the braiding machine,
thus to avoid repeated spooling and respooling.
In order to answer this double purpose the bobbin is made without a rim
or flange at both ends; at one end it is cut off quite straight and at the other it

page_text: is provided with the indentations as usual and its shape on the whole is cylindrical
with a slightly concaved outline lengthways and in order that it may be con
veniently and readily fixed on the spindle of the spinning machine I combine it
with a suitable holder or box on to which it is stuck and which with the bobbin
upon it is held securely upon the spinning spindle, by which means the turning
of the bobbin on the spindle is prevented. Said holder however does not form
part of this patent and it is shown for the better understanding of the use of the
new bobbin with the spinning machine.
My new bobbin and the manner of mounting it upon the said spinning spindle
box is shown on the accompanying drawing and also its combination with the
bobbin holder of the braiding machine.
Fig. 1 is an outside view of the bobbin ;
Fig. 2 is a vertical section of the same;
Fig. 3 shows one form of the spindle box used together with the bobbin and
with toothed foot;
Fig. 4 is a longitudinal section of the same with the bobbin mounted thereon;
Fig. 4 is a cross section of the same;
Fig. 5 is an outside view of a spindle box with a straight foot;
Figs. 6 and 7 show two views of a varied form of the spindle box;
Fig. 8 show the same with the bobbin put thereon;
Fig. 9 shows a bobbin with the yarn wound upon it crossways;
Fig. 10 shows a slight modification of the bobbin allowing straight winding;
Fig. 11 show this bobbin with the yarn wound thereon in parallel windings;
Fig. 12 is a vertical view, partly in section of a bobbin holder with the new
bobbin put thereon.
The bobbins in use hitherto with braiding machines are all made with flanges
at bottom and top and at one end the upper side of the rim is provided with
teeth; my new bobbin consists of a plain wooden tube a (Fig. 1), one end of which
is provided with the teeth b; its outside is in its longitudinal direction by pre-
ference a little concave, but it might be quite straight.
This bobbin I put upon a box g, which is held fast upon the spinning machine
spindle; it consists of a lower thicker part c of exactly the same diameter as the
bobbin and of an upper thinner part d, round which is placed a spring or
tube o of thin steel plate and partly split at its lower end, as shown at f, so that
this part acts as a spring. This tube is of the same thickness as the hole in the
bobbin, the lower spring part being a little wider, so that the bobbin is held
thereon securely by the springing action of the tube; for this purpose the
middle part of the box g is made somewhat thinner so that the spring e can
play. The shoulder of the thickened part is provided with teeth 6' which
correspond exactly with the teeth 6 of the bobbin; so that when this is put
upon the box and pressed quite down, the box and the bobbin form, as it were,
one object; the engaging teeth b and bi preventing the turning of the bobbin in
case the spring e should not act sufficiently.
Figure 5 shows a variation of the box, differing from the one described only in
this, that the shoulder is here cut quite straight instead of being provided with
teeth.
In Figures 6, 7 and 8 is represented an other variation of a box g¹ having the
thickened lower part e¹ with teeth b¹ like that shown in Figs. 3 and 4 but instead
of the spring tube e, round the thin part 1, I here use a flat spring el which
partly lies in a recess of the upper reduced part of the box at its upper
end this spring has a nose or projection which springs over the upper edge
of the bobbin and holds it securely in its place.
It is found advantageous that the thread or yarn is wound upon the bobbin
shown and described, crossways as indicated by Figure 9, so that the windings
do not fall over each other when the yarn is pulled off or unwound.
§
But since it is more convenient to wind the yarn in parallel layers as shown
by Fig. 11, I provide the bobbin a¹ with small circular recesses or grooves m

page_text: as indicated by Fig. 10, These recesses serve to hold the yarn upon the bobbin,
and when wound up in a conical form, as shown in Figure 11, these windings
will also hold safely and not fall assunder when the yarn is pulled off.
Figure 12 shows an ordinary bobbin holder for braiding machines, from which
it will be seen that my new bobbin can be used and is held thereon in the
same manner as the old bobbins with flanges.
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:
1.) A bobbin for braiding machines fit for having the yarn wound upon it direct
on the spinning machine and consisting of a plain cylindrical tube a having a
slightly concave outside and being provided at one end with the teeth its other
end being cut off straight, as shown in the drawing and as described.
2.) In combination with a bobbin as specified in Claim One, circular recesses
or grooves (m) at both ends of the bobbin as illustrated and described and for
the purpose set forth.
