PROVISIONAL SPECIFICATION.
Improved Wire Heddles for Looms.
I, MAX STRAKOSCH, of 37 Mariahilferstrasse, Vienna, in the Empire of Austria,
Merchant, do hereby declare the nature of this invention to be as follows:-
It has hitherto been customary to manufacture heddles for looms in such manner
that the ends of the twisted wire terminated in the neck of one of the loops, and
thus the projecting ends interfered with the next or adjacent warp-threads during
the raising and lowering of the shafts.
All attempts to arrange these ends of the wires in other parts have failed for
the same reason, or because the heddles became too thick and rigid, and therefore
required more space in the shaft.
With my improved wire heddles forming the subject-matter of this application,
all these defects are overcome, which is a great advantage, especially in connection
with the manufacture of twilled, fancy or similar fabrics.
In making these heddles according to my invention, I use a continuous wire,
loop or ring, whereby the neck of the loop is made of equal thickness, and it is
not necessary to employ special means for covering or protecting the ends of the
wires. Such ends of the wires are joined or united by welding, soldering or other
suitable manner, so that an endless wire is produced, which is then subjected to the
twisting operation.
This is done in the usual manner by means of a known machine for twisting
wire heddles, whereby an eye is formed in the centre of the heddle and loops on
the ends of the double end parts.
Heddles formed in this manner have no projecting points or ends which may
injure or damage the warp thread by friction.

I, MAX STRAKOSCH, of 37 Mariahilferstrasse, City of Vienna, in the Empire
of Austria, Merchant, do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
It has hitherto been customary in the manufacture of heddles for looms, that
the free ends of the twisted wire forming the heddle were made to terminate at
the neck of one of the eyes or loops; these free projecting ends, therefore, very
often came in contact with and damaged the adjacent threads of the warp during
the raising and lowering of the shafts.
All attempts to arrange such ends of the wires at other parts have failed for
the same reason, or because the heddles were rendered too thick and rigid and
therefore took up more space in the shaft.

page_text: By means of my improved wire heddle forming the subject-matter of this
application, the above-mentioned defects are overcome; its great utility will
therefore be evident, especially in connection with the manufacture of twilled fancy
or similar goods.
In order that my invention may be thoroughly understood, I will now describe
same with reference to the accompanying drawing, in which :-
Fig. 1 is an endless wire of which the heddle is formed;
Figs. 2 and 3 show the manner of forming the heddles;
Figs. 4 and
are side and front views respectively of a finished heddle.
Fig. 6 shows the eyes on a larger scale.
The heddles are made in the following manner :-
A wire b is wound as closely as ever possible on a hollow or solid mandrel a
(Fig. 2) the free ends of the wire being then suitably secured.
After being deoxidised or cleaned in the usual manner, powdered or granulated
solder, or even a plate of same, is put on to the wires, for instance between the
lines c, d, e, f, (Fig. 2) and then heated by means of an iron or in other suitable
manner, the wires wound on the mandrel a, being thus soldered together at the
parts c, d, e, f.
As shown in Fig. 3 on a larger scale, the wires thus wound on the mandrel a
.and soldered are formed into the endless wires as shown in Fig. 1 by obliquely
cutting through the solder and wires at the part c, d, e, f in such manner, that
wire 1 is connected with wire 2, wire 2 with 3, etc. The endless wire b' thus
resulting may be made of various forms according to the shape of the mandrel a.
This endless wire is now twisted or turned in the usual manner, by means of
.any, of the known machines for twisting wire heddles, the eyes h, g, h, being thus
formed.
Heddles made in the above-mentioned manner, therefore, are free from projecting
points or ends, which could damage the threads of the warp by contact or friction
during the raising and lowering of the shafts.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
'claim is :-
--:
1. Improved wire heddle for looms, consisting of an endless wire, substantially
as described and shown in the drawing.
2. The method of making heddles as set forth in the foregoing claim, consisting
in closely winding wire on to a mandrel (such as a) and then soldering at any
suitable part, obliquely cutting through two succeeding wires and, finally, twisting
the resulting endless wires in the form of heddles by means of any well known
machine, substantially as described and shown in the drawing.
