Improvements in Loom Heald Shafts.
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 :-
It is well known, that wooden loom shafts will easily bend and break during the
process of weaving, especially if their thickness is limited to eight millimeters, to
afford room for a great number of shafts. Loom shafts have therefore been
made of metal, but their weight is a drawback in the case of quick running looms
having many shafts.
In order to combine lightness with strength, I have adopted the construction
represented by the accompanying drawings, in which,
Fig. 1 is partly a front elevation and partly a vertical section of a shaft or pair
of shafts embodying my invention,
Fig. 2 is a vertical transverse section of the same,
Fig. 3 represents a modification.
A pair of these shafts chiefly comprises two flat wooden bars a, a', to which are
rivetted, nailed, or screwed a pair of metallic rails b, b'.
The said rails are U shaped or channelled, as shown, and leave sufficient
clearance between the edge of the wooden bar and the bottom of the rails, to afford
room for the heads of the rings or holders e, e which are adapted to slide along
the rails.
The wire heddles c c are connected with the shafts at the ends by means of
wires dd, placed parallel to the inner edges of the shafts, and bent vertically at
the ends, to prevent the outermost suspension rings e from sliding out of the rails
or channel irons b, b, enclosing the heads of the said rings.
Instead of bending the wires d and introducing the ends into the wood, as
shown, I may use bolts / screwed vertically through the shafts a, a, and projecting
sufficiently to form abutments for the heads h of the rings e, e.
In the case of shafts having a single row of heddles, a single wire d is placed
along the edge of each shaft, as represented by Fig. 2; in the case of shafts having
two rows of heddles there are two parallel wires arranged at the same level and
held by the same rings or holders e, which for this purpose have a special shape, as
shown by Fig. 3.
The rings or holders e are composed of a head or base plate and a piece of
wire, which in the case of single rows form an ordinary eye (Fig. 2) and in the
case of double rows, a double eye (Fig. 3). The ends of the said piece of wire
pass through the said base plate and are bent down or rivetted.
By means of the improved shafts, which combine great lightness with solidity,
it has become possible, to use wire beddles also in quick running looms having
n.any shafts. Moreover, steel-wire-heddles may be easily and conveniently
arranged in two rows, even when they are placed very close together as in silk
looms.
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 I
claim is :-
:-
A loom-shaft (or nair of shafts) chiefly comuosed of wooden bars a
and

page_text: narrow metal rails or channel irons 6 6' fixed to the said bars, said shafts being
provided with adjustable holders e adapted to carry a single or a double row of
heddles by means of wires d, and held in place by bending the ends of the wires d
towards the wooden bars a, a', or by providing the said bars with bolts 1, substantially
as described.
