COMPLETE SPECIFICATION.
Improvements in Healds for Looms.
I, WILHELM MARGGRAFF, of Betzingen, in Wurttemberg, Germany, Manu-
facturer, 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:-
The present invention refers to an improved link-heald which obviates the
inconveniences of those used till now, and which through its simplicity permits
the heald to be manufactured cheaply and of great durability.
The accompanying drawings show on an enlarged scale a front and edge view of
the improved link heald, in which the links are preferably punched with D shaped
holes at their ends, and a detail of one of the free ends twisted.
The improved link-heald is made of a flat tape of steel or other suitable metal
which passes through the end holes of the links (afterwards employed as
thread rings) in the following way: The tape is doubled over and then twisted
half round, so that in Fig. 1 the flat tape is seen from its edge or narrow side.
In this way an extreme mobility is attained in the links without decreasing the
durability of the heald. The free ends of the doubled flat wire, which can be
soldered or attached completely or partially in any preferred manner or even
left free, are twisted or wound several times in the way shewn in Fig. 3 and are
formed in the shape of an eye or loop.
The advantages of a link-heald of flat metal tape of this sort are:
1. Indentations on account of clogging of the chain at the links are prevented
and the consequences thereof such as the tape bursting or cutting through the
link and like inconveniences are avoided.
2. It takes less room in the yarn-chain and provokes less friction in the weav-
ing.
3. It is free to move in the links, without its being possible for the top or bottom
part of the tape to become undone.
4. In consequence of its free working in the links, it cannot be bent, and allows
the weaver to work the tackle without hindrance.
5. There is no unevenness in the joints between the links and top and bottom
parts of the tape.
6. It is considerably cheaper in production than other healds, with a specially
fitted or soldered description of link.
7. It is of much greater durability than the healds which are sharply twisted
round several times at the links, and therefore are easily broken at these points.
8. It cannot buckle or bend, as being made of flat tape it is always parallel
to the chain threads.
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:-
A link heald formed of metal tape, of steel or any other suitable metal with
suitably prepared links as herein specified.

page_text: The tapes are passed through the end-holes of the links, doubled over and
twisted half round, so as to ensure a perfect mobility in the links, and its free
ends are twisted or wound several times and formed like an eye or loop, as herein
described and set forth.
