COMPLETE SPECIFICATION.
Arrangement for Moving the Batten in Wire-weaving Looms by
Means of Motive Power.
I, IRÉNÉE LANG, of Schlettstadt, in the German Empire, Manufacturer, 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 relates to an arrangement for moving the batten in wire-
weaving looms in which the backward movement of the batten is effected by
manual labour supplemented by motive power, whilst the forward movement is
caused by the gravity of the batten. In small weaving looms the batten can easily
be actuated by hand, as is customary in textile-weaving looms for the production
of linen, etc. Weaving-looms of heavier construction such as are employed in
the manufacture of wire gauze do not permit of the batten being actuated by
hand; this being effected by means of a leather-belt or band placed over pulleys
and actuated by means of a treadle lever. This manner of working the batten
however requires great exertion, to reduce which is the purpose of the present
invention, in which the employment of motive power serves as an auxiliary
assistance to the weaver. The solution of this problem entailed considerable
difficulties as the arrangement has to be of simple construction.
By way of an example I have shown in the accompanying drawings a mode of
carrying out my invention. This construction combines simplicity with effective-
ness without necessitating a re-construction of the weaving loom.
Figs. 1 and 2 are diagrammatic views of my arrangement in connection with a
weaving loom; the batten being shown in different positions.
Fig. 3 is a plan of Fig. 1.
The batten a is suspended in the usual manner and provided at the bottom end
with two or more projecting hooks c, to which the cords are fastened. These
cords bare secured to discs d, the latter being rigidly connected with a shaft e
rotatably supported in suitable bearings in the weaving-loom-frame. A disc f
is secured at the centre of this shaft e. A strap wound around this disc f leads
over the guide pulley and thence to the treadle lever k, pivoted at i, to which
it is fastened. On depressing the treadle lever k as shown in Fig. 2, so that it
assumes the position illustrated in Fig. 1; the strap g is tightened and subse-
quently the shaft e rotated, thereby causing the cords 6 to wind around the discs d
and so cause the batten a to be moved backwards. The present invention has for
its purpose to facilitate this action, by imparting a continuous rotation to the
guide pulley h. With this end in view the guide pulley h is mounted on the
shaft, the latter being constantly rotated by any suitable transmission gear
from any desired source of motive power. A belt m and pulley o are
illustrated in the accompanying drawings as one mode of effecting this pur-
pose. On now depressing the treadle lever the strap g will be pressed
tightly against the guide pulley h and by virtue of the friction, motion will
be imparted to it from the rotating guide pulley h. My improved arrange-
ment as herein before described enables the batten to be easily moved backwards.

page_text: In depressing the treadle lever k a spiral or like spring p is put in tension the
upper extremity of the spring being fastened to a strap, placed around one of the
discs on the shaft e, the other end of the strap being secured to the treadle lever k;
whilst the other extremity of the spiral spring p is fast to the base of the weaving-
loom. On releasing the treadle lever the tension of the spring returns the
treadle lever to its original position. In view of the stiffness of the strap git
will separate from the guide pulley in the return movement of the treadle
leverk, so that almost unimpeded swinging forward of the batten is attained thus
ensuring a blow with its full force on to the web. It might be desirable to trans-
mit the motive power directly to the shaft e, but this arrangement would present
several difficulties which make the arrangement above described the preferable
one. It may however be mentioned here that instead of actuating the strap g by
means of a treadle lever a hand lever may suitably be employed.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
1. An arrangement in combination with swinging battens of wire-weaving
looms for causing the backward movement of the batten by means of motive
power in addition to the usual means, substantially as set forth.
2. An arrangement for aiding the backward movement of the batten in a wire-
weaving loom consisting in imparting continuous motion to the shaft in com-
bination with the usual means for actuating the batten, substantially as set
forth.
3. Arrangement for moving the batten in a wire-weaving loom by means of
motive-power-in-addition-to-the-usual-means, the whole-being-arranged-and-
adapted to operate substantially as described with reference to the accompanying
drawings.
