I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35 Southampton Buildings, Chancery Lane, London, in the County
of Middlesex, do hereby declare the nature of this invention to be as follows:-
This invention has for its objects improvements in the method of, and devices for,
mounting the heddles used in ordinary weaving looms, so that the working of the
loom is improved, with a regular and uniform production of work. For this
purpose the heddles are attached to the staff or lath which carries their ends, in
such manner that a sufficient movement is possible upon such lath in the direction
of its length, for the purpose of adjusting them. Moreover, the heddles have an
increased mobility, as instead of the guides or "mails" for the warp threads being
carried at the centre of a heddle consisting of a single wire, as heretofore, each half
of the latter is also provided with one or more additional links at or near its ends.
In order to allow the mounting and adjustment of the several heddles, each staff
or lath is surrounded by a sheet metal casing, the sides of which rise above the
sides of the lath (supposing that the lower lath is being described) and are then
bent over so that their edges form a longitudinal slit at a sufficient distance above
the lath, and in the direction of the length of the latter, so that the different
heddles may be adjusted in the desired positions in the slit. The eyes at the ends
of the heddles are held or threaded upon a wire or rod which passes through them,
its ends being fixed in the ends of the lath, which project up sufficiently for the
purpose. The slit described is of such width as to allow the heddles to pass freely
through it, the eyes at their ends being held in position by the wire or rod passing
through them, but being capable of moving end ways upon the lath.
In a somewhat modified form of arrangement the edges of the plate, which form
the longitudinal slit, are bent down for a sufficient distance, and instead of eyes at
the end of the heddles, the latter are bent round in the form of hooks which fit
round and are held by the turned down edges. Suitably shaped plates at the ends
of the lath close the passage for the hooks and prevent them from coming off the
ends of the lath. A special advantage of the improved arrangement is, that the
heddles can move horizontally to or from each other. Moreover, the weaver can
very easily and quickly remove, change, and adjust the heddles into any desired
position.

Improvements in Loom Heddles.
A communication to me from HERMANN KATTENSTEIN, of Bludenz, Tyrol,
Manufacturer.
I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex, 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, and accompanying drawing, that is to say:-
This invention relates to improvements in the method of, and devices for,

page_text: mounting the heddles used in ordinary weaving looms and the object of the
improvements is to facilitate and to improve, the working of the loom and to
produce a regular and uniform production of work.
For this purpose the heddles are attached to shafts which carry the ends of the
heddles in such a manner that a sufficient movement of the heddles in a lateral or
sideward direction is possible for the purpose of adjusting, the position or width of
the heddles. Moreover the heddles have an increased mobility, because not only
the guides or mails for the warp threads are joined in the middle of the heddles by
flexible joints, but also the upper and lower ends of the heddles are provided with
one or more additional links, flexibly jointed thereto.
In order that the invention may be more fully understood, reference is made to
the accompanying sheet of drawings, in which :-
Figure 1 is a vertical cross section through the upper and lower shaft,
Figure 2 is a front view of the shafts and the heddles, partly in section,
Figure 3 is a view similar to Figure 2, and
Figure 4 a cross section similar to Figure 1, shewing a modified form of the
shaft,
Figure 5 is an end view, and
Figure 6 a front view of the shaft represented in Figures 3 and 4,
Figures 7, 8, and 9 illustrate some modifications of the heddles.
In order to allow the mounting and adjustment of the several heddles, each
shaft c (preferably made of wood) is surrounded by a sheet metal casing a, the
sides of which rise above the sides of the shaft c (supposing that the lower shaft
(Figure 1) is being described) and are then bent over, so that their edges form a
longitudinal slit in the direction of the length of the shaft and at a sufficient distance
above the latter, as shown in Figure 1, so that the different heddles may be adjusted
in the desired positions in the slit.
C
The eyes at the ends of the wire heddles fare held or threaded upon a wire or
rod b which passes through them, its ends being fixed between the projections or
shoulders projecting up sufficiently over the shaft c. When the heddles are
threaded upon the rod and the latter is put between the projections c² of the
shaft e the said shaft is inserted into the casing a through one of its open ends,
the heddles sliding along in the slit of the casing a.
This slit is of such width as
to allow the heddles to pass freely through it, the eyes at their ends being held in
position by the rod passing through them. By this arrangement the heddles are
held reliably in the shafts, but are capable of moving sideways upon the rods b in
one or the other direction. In order to prevent the heddles especially the eyes of
the heddles, from chafing on or against the edges of the slits, there are arranged
upon the rods b in intervals of about 50 to 100 heddles thin sliding plates d having
a triangular or square form, (Figures 1 and 2).
In a somewhat modified form of arrangement, as shewn by Figures 3 to 6, the
edges a² of the plate a', which form the longitudinal slit, are bent into, the interior
of the casing for a sufficient distance, and instead of eyes at the ends of the
heddles, which are to be put upon the rod b, the ends of the heddles are bent
round so as to form hooks, which fit round the inwardly turned edges a² of the
casing a¹.
The shoulders or projections of the shaft c are slotted or grooved so that on
each end of the shaft two studs are formed. This shaft c is also inserted into the
casing a through one of its open ends. The studs or branches c³ therefore close
the passage for the hooks of the heddles and prevent them from coming out of the
passage formed by the inwardly bent edges a' of the casing a¹ (Figure 3)..
Figures 7 and 9 illustrate wire-heddles f, which have their mails e inserted and
attached by flexible joints, the heddles shewn by Figures 8 and 9 are provided
with additional links flexibly jointed thereto.
A special advantage of the improved arrangement is that the heddles can move
horizontally to or from each other. Moreover, the weaver can very easily and
quickly remove, change, and adjust the heddles into any desired position.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what 1
claim is :-
--
1. A method of attaching heddles, provided or not with additional links
flexibly jointed thereto to the shafts of looms in such a manner, that the heddles
are capable of moving freely in a horizontal direction to or from each other.
2. A shaft for mounting the heddles consisting of a sheet metal casing a, having
a longitudinal slit, a shaft e with projections or shoulders at its ends and a wire
or rod passing through the eyes of the heddles and placed between the pro-
jections c', substantially as described with reference to Figures 1 and 2.
3. A. modification of the shaft for mounting the heddles according to the
improved method, consisting of a sheet metal casing a having a longitudinal slit
and inwardly turned edges a² on which the heddles are hooked, and a shaft c
with studs or projections c³, substantially as described with reference to
Figures 3, 4, 5, and 6.
