Improvements in Shafts or Healds of Looms for Weaving.
I, CARL THEOPHILUS HUNGER, Manufacturer, of 29, Schillerplatz, Chemnitz,
in the Kingdom of Saxony, 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 relates to leaves or shafts made of or with wire heddles, aud
more particularly to the means for connecting the wire heddles with the laths and
the laths with cach other, as will be seen from the accompanying drawings, in
which
Fig. 1 is a front elevation of a shaft embodying my invention; Fig. 2 is a
vertical section of the same;
Figs. 3 to 10 represent details of construction.
The bealds are mounted at their ends on a pair of horizontal wires or heald-
carriers a, a, by means of eyes formed at the ends of each heald. The said
wires a are bent round at their ends, as shown, and connected with the laths, c
by means of holders b, bi, b₂, ba, also made of wire. Each of the said holders
forms a loop around the lath and is adapted to slide on the same to and fro, so that
during the operation of weaving, the said holders can easily be shifted to the
required place by means of the warp, and can be pushed aside if the weaver
passes his hand through the harness to draw in a broken warp thread. The ends
of each holder forming a loop are bent and united in various ways, so as to form
one or two eyes or hooks of any desired shape, some of which are shown by
Figs. 3, 4, 5, 6, 7, 8 and 9.
Another feature of novelty consists in connecting the two laths and c₂ by
means of clamping wires d. d , which enclose the two laths either at the ends alone
or at the ends and near the middle (according to the width of the shaft) and are
tied together by means of the tie wires f, f.
This connection between the upper and lower lath has for its object to relieve
the heddles of any strain that may be transmitted from one lath to the other in
the process of weaving, which strains might prevent the beddles from being shifted
to the required spot by the warp threads, and thus produce streaks in the
woven fabric, besides tending to break the heddles in the middle, that is, through
the eye.
Each of the said clamping wires d . . d, forms a spring hook e and is sunk in a
groove of the lath, as shown by Fig. 1.
These lath ties d, f, da; d, f, d, &c., can be easily removed and replaced when it
is desired to take off one or more of the heddles from the shaft, and they serve to
keep the laths always exactly at the same distance apart, so that the heddles
possess the necessary lateral mobility.
In the case of ordinary lath ties consisting of screw threaded bars, this can only
be effected with much care and loss of time.
In comparison with shafts having rigid frames where the two laths are connected
by means of rigid wooden or iron bars fixed to the laths, the shaft above described
has the advantage of lightness, the wire connection d being much lighter than
the rigid sides of the frames just mentioned. Consequently, shafts of wire heddles
constructed according to the present invention are applicable also for light and
quick running looms.
For suspending the shaft in the loom, the laths c c are provided with detachable
loop wires g (Figs. 1 and 10) which pass through perforations in the laths and can

page_text: be easily exchanged if it is desired to suspend the shaft in another loom which
necessitates a change in the distance between the extremities of the upper and
lower suspenders g g.
In the drawings, Figs. 3 to 7 show various forms of holders b, suitable for
suspending a single heddle carrier a, while Figs. 8 and 9 show holders b suitable
for suspending a pair of heddle carriers a.
Fig. 10 shows the method of applying and removing the loop wires
Having now particularly described and ascertained the nature of my inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A shaft or leaf of wire heddles having movable holders b adapted to suspend
the heddle carriers a from the lath c, each holder being bent of one piece of wire
and forming a loop around the said lath, substantially as described.
2. In a shaft or leaf of wire heddles, the means for connecting the upper and
lower lath, consisting of a pair of elastic wire clamps e bent of one piece, and a tie
wire connecting the said clamps, substantially as described.
3. A shaft or leaf of wire heddles provided with detachable loops g bent of
one piece of wire and adapted to suspend the shaft in the loom, substantially as
described.
