We, FRANZ OSKAR DATHE and CARL WILHELM GÖHLER of Hartha in the Kingdom
of Saxony, Germany, Manufacturers, do hereby declare the nature of this invention to
be as follows:-
It is known that heddles made from ordinary iron wire are very liable to bending,
especially when they are bent out of the row for the introduction, of threads. The
application of steel wire however has hitherto met with difficulties, since steel wire
owing to its elasticity resumes its original position and shape, which has hitherto pre-
vented the formation of a satisfactory eye in the heddles; the rim of the eye should
also be round and smooth to prevent the threads from being cut by the same. To
allow a heddle to be made from steel wire without these inconveniences, it is, according
to this invention, formed by the following process:
The heddle is made from two wires lying side by side and soldered at the places of
contact, which wires are bent asunder at the place destined for the eye, the wires being
at the same time so secured, that only the place intended for the eye, remains free.
The wires curved outward in this manner are then twisted near the eye to prevent the
wires from being torn apart near to the eye. To allow of an absolute twisting of the
wires the heddle is clamped fast in a peculiar manner except at the eyelet part, which
clamping must be different according to the manner of twisting and the thickness of
the wire.
The arrangements for this process consist essentially of two devices, one for bending
out the wires and the other for twisting the same.
For the purpose of bending out, the wires are laid into an adjustable slit adapted to
be made broader or narrower by means of a displaceable plate according to the

page_text: thickness of the wire, in such a manner, that the place where the eye is to be formed
lics between two sliding stamps. The latter lie opposite each other, but one above the
level of the other in such a manner, that the upper stamp abuts upon the upper wire
and the lower upon the lower wire, that is to say, the one wire is pressed from the
right, to the left, the other from the left to the right, so that the wires are bent
asunder.
The stamps are suitably guided and provided with vertical pins, which catch into
the shanks of a pair of spring-pincers. By pressing together the handles of the latter,
the wires are pressed apart whereby the eye of the heddle is formed. The heddle
provided with the eye is now twisted as required, the eye hole being simultaneously
smoothed and rounded. For this purpose an apparatus is employed consisting
essentially in a clamp, which presses fast, during the twisting, the places contiguous to
the eye.
The heddle is laid into a slit of a divided block and a corresponding clamp-
ing block is fastened above it this device holds the wires at a suitable distance each
side of the eye, leaving however the latter free.
The eye of the thus secured heddle is now turned by means of an angle hook intro-
duced therein but so constructed as not to injure the wire. This device for clamping
the beddle is remarkable by the manner of operating the upper clamping plate so as
to give greater or less pressure on the heddle wire.
This is effected by attaching the upper clamping plate to a horizontal balance arm
pivoted in the frame of the machine, and which serves as a rail for supporting a
movable weight which may be easily shifted along the arm, so as to lift up the upper
clamping plate, or press the latter down with more or less pressure.

page_text: We, FRANZ OSKAR DATHE and CARL WILHELM GÖHLER, of Hartha in the Kingdom
of Saxony Germany, Manufacturers 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 consists in an improved method and apparatus for the manufacture
of heddles from steel or other wire.
It is known that heddles made from ordinary iron wire are liable to be easily
bent especially during the introduction of threads, whereas, although heddles made
from steel wire have not this disadvantage, they have not hitherto been generally used
or made owing to the difficulty experienced to forming and retaining a suitable eye in
the steel wire.
The improved heddle is made from two steel wires placed side by side and soldered
along the length in which they are to be in contact, that is to say preferably along all
parts except where the eye is to be formed.-The wires are then bent apart at this
place, they being firmly clamped during this part of the process except at the parts
under operation of bending-The wires having been curved outward to form the eye
as aforesaid, are now twisted together for a certain length on each side of the eye, to
prevent them from being torn apart, and the heddle is finished.
The mechanism necessary for performing this process of manufacture is shown in
the annexed drawings, of which sheet 1 illustrates the implement for bending apart
the wires to form the eye and sheet 2 illustrates the machine for use in twisting the
wires together to a certain distance each side of the eye.
Referring to sheet 1.
Fig. 1 is a side elevation Fig. 2 a plan of the implement for forming the eyes.
Fig. 3 is a section showing the mechanism in its position before bending apart the
wires Fig. 4 is a similar section after bending apart said wires, both sections being
taken in a plane perpendicular to the heddle and passing through the eye of the
same.
Fig. 5 is an enlarged detail view of part of Fig. 2.
On a suitable base are screwed two plates B B₁ having a space between them
sufficient to admit of the insertion of the beddle, the said plates being adapted to
clamp the heddle so inserted, for which purpose the plate B is capable of being moved
towards the plate B' and secured at the requisite distance therefrom. The plates B
and B contain respectively the sliding bars 6 and d. The bars are arranged to move

page_text: in the same line but the one bar (preferably d) is guided at a lower level than the
other bar, so that the inner ends of the bar are capable of being moved one under the
other The said ends of the bars bd are curved preferably semicircularly, and are
adapted to be pressed one against each wire of the heddles from opposite sides at that
part of the heddle where the eye is to be formed, so as to curve the respective wires
away from each other and so form a substantially circular eye between the wires. For
the movement of the bars 6 d-pins e e are provided thereon, engaging in slots in
levers D D pivoted at one end to the bed of the implement and shaped at the other
end to form handles D D¹ by which the levers may be pressed together. The
levers D D are normally held apart by a spring or springs.
The heddle provided with an eye in the manner described is transferred to the
machine shown on sheet 2.

heddle-Fig. 14 being a cross section through the same.
To a suitable bed plate is secured adjustably in a horizontal plane, the upright K,
the upper end of which carries the pivot supporting the balance beam J, the same
forming a rail or track for the weight carriage H.-The upright K carries the screw
which receive and guide the bar to which the upper forked clamping plate F is
attached, the said bar being connected to the aforesaid track J-The carriage H con-
sists of a wheel having attached to its bearings and slung thereon, weights H, and
also means for attaching a cord passing over pulleys at the ends of the track and over
a pulley having a crank handle, and carried on a pin fixed to the upright K-Under
the forked clamping plate F is arranged a pair of pillars EE one for each face of the
clamping plate, the faces of the pillars and of the clamping plate being shaped to
thereof against
retain the wires of the heddle at a suitable distance each side of the
turning when the clamping plate is brought down with pressure on the pillars E E-
This is effected by turning the hand pulley aforesaid by which the weight carriage is
drawn to the front part of the track J, so that the said track is depressed about the
pivot f. thus carrying down the clamping plate F with pressure proportional to the
distance of the weight carriage from the pivot f. The travel of the carriage H
on the track J can be limited towards either end of the track by dogs such as
shown in Fig. 9 adapted to be clamped at suitable distance from either end along
the track.
eye
The heddle having been placed on the pillars E E with the eye in the space i
between the pillars, the forked plate F is brought down thereon in the manner before
mentioned, and the bent lever G (Fig. 12) is introduced in the manner shown in Fig. 6
into the eye of the heddle, the end of said lever being rounded so as not to cut or tear
the edges of the eye-The lever G is then turned down through the opening and the
eye of the heddle twisted thereby for any convenient number of turns.
To hold the heddle in position in this machine, the outer end or ends of the heddle
are held by a disc or discs L adjustable to and from the pillars E as indicated in
Figure 7.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is ;-
1. A heddle composed of two steel wires in contact having an eye derived by bend-
ing apart portions of said wires the wires being twisted above and below said eye
