COMPLETE SPECIFICATION.
Double Wire Heald for Warp Staves with Two Parallel Heddle
Rows.
We, MAX ALFRED FICKER and CARL GEORG HENTSCHEL of Chemnitz in the
Kingdom of Saxony, Empire of Germany, Manufacturers, do hereby declare the
nature of this invention and in what manner the same is to be performed to he
particularly described and ascertained in and by the following statement :-
The object of this invention is to remove the drawbacks inherent to the weaving
appliances hitherto known in which the healds are distributed in two parallel rows on
the weaving shafts. The latter arrangement is made on the one hand in order to
afford as large an interstice as possible between the healds, thus diminishing the
friction of the warp threads, on the other hand because the number of healds required
for making close fabric cannot in most cases be distributed in one row
determinable width of staff.
on the
For the purpose of forming from wire healds a shaft with two parallel heddle rows,
each two of the same were heretofore united at their end eyes by thread loops and
subsequently so arranged on the warp staff, that one wire heald comes to lie at the
front side and the other at the rear side of the staff looms. With the application of
wire healds thus connected the inconvenience arises that the thread loops wear out in
an unproportionally short time, thereby causing many disturbances in work and
faults in fabric, not to speak of the expensiveness in renewing said loops. It also
entails great difficulty and expense to so alter staves, consisting of wire healds with
thread loops relatively to their number of healds as is required for producing new
patterns.
Another material drawback consists in the liability of the single healds to turn
about their axis and so place themselves that the thread grinds out the tin, at the
point indicated by Fig. 7 of the drawing hereafter referred to, between the wires
forming the heddle eye, the thread thereby is cut and frequently torn, which cannot
bappen if the heald is compelled to so adjust itself to the thread as indicated by Fig. 8
of said drawing, in which position the thread rests not on the tin but on the wire
forming the heald.
The double heald forming the object of the present invention has for its purpose
to render, in staves with double-row position of the wire healds, the connection of the
latter by means of thread loops entirely superfluous, the improved double heddle
consists of two wire healds with one thread eye (maillon) each, which are either of a
piece or so connected with one another as to prevent either of them from turning
about its own axis.
Reference being had to the accompanying drawing illustrating some forms of
execution of the invention.
Figs. 1 and 2 illustrate two wire healds bb provided with thread loops, but so
connected with each other at both ends c by solder, twisting or in a similar manner as
to form a double heald, the thread eyes (maillons) of which cannot turn about their
own axis, when it is shifted on the staff bars d d¹.
Figs. 3, 4, 5 and 6 show a form of application, in which a wire heall b provided
with two maillons a a¹ is bent round hair pin fashion within the two maillons and is
onnected at e Fig. 3 in the same way as in Figs. 1 and 2; or the ends are each
provided with an eye serving for fastening Figs. 5 and 6.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we' declare that what we
claim is:
A double wire heald applicable for weaving staves with two parallel heddle rows

page_text: and in which the parallel heddle shanks each provided with a thread eye, are so direct
connected with each other at one end or at both ends that in the shaft none of the
shanks can turn about its own axis, while nevertheless the requisite play of the
warp threads with the beddles is allowed substantially as and for the purpose set
forth.
