COMPLETE SPECIFICATION.
Improved Apparatus for Adjusting the Heald Shafts in Power
Weaving Looms,
I, AUGUST BOECKER, Director of Weaving Works, of 39, Chausseestrasse, Arns-
berg, Westphalia, in the Empire of Germany, 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:-
_
This invention for improved apparatus for adjusting the heald shafts in power
weaving looms has for its object to provide an adjusting device for the heald shafts
of weavers' looms by means of which the said shafts can be readily adjusted to
any required height, the adjusting or regulating apparatus being attached to the
loom by hooks and eyes, and the whole arrangement or contrivance being.then
suspended on the upper shaft.
In the accompanying drawing:-
Fig. 1 is a view of two loom shaft regulators of the kind applied to a weaver's
loom,
Figs. 2 and 3 are enlarged views of the apparatus, taken at right angles to
each other.
The heald shaft adjuster consists of a rounded metallic rod or staff 1, part of
which is cut away at 4, as shown in Figs. 2 and 3, leaving a solid central part 2
and two ends 3, these latter being bored and tapped to form nuts for receiving
the screwed shanks of hooks 5.
The shanks of the hooks 5 are screwed into the nuts 3 one having a right and
the other a left hand thread.
If the hooks be made fast, and the metallic sleeve or staff 1 be rotater, both
of the screws will be turned in their nuts and, according to the direction of rota-
tion, the whole arrangement or contrivance will be lengthened or shortened.
This lengthening or shortening, is applied as shown in Fig. 1, to the regulating
or adjusting of the heald shafts by hooking a pair of the apparatus in the holes
in the strap on the upper shaft thus hanging the whole contrivance or arrangement
in the upper shaft belt or strap, which serves for the raising of the heald shaft.
As the springs 7 continually draw the shaft 6 downwards, the shaft 6 can at
any moment and without loss of time be adjusted to any given position, by the
rotating of the adjusting device to the left or to the right. The position of adjust-
ment remains fixed.
In comparison with the methods hitherto employed, in which the heald shaft
is adjusted by means of cords or twine, this apparatus is distinguished by its
simplicity of application and the facility of adjustment.
As compared with those adjusting contrivances, which are operated by means of
hooks and chains, the present apparatus has the great advantage that the shaft
can be adjusted to any desired height, whereas the hook and chain contrivances
only allow of adjustment within the limits of the length of the chain links,

invention and in what manner the same is to be performed, I declare that what
I claim is
65
1. Apparatus for regulating or adjusting the heald shafts in power weaving
looms, the distinguishing feature of which is that two hooks 5 furnished with left
and right hand screw threads, are screwed into a metal piece 1 so that, when the
hooks are made fast, a shortening or lengthening of the whole contrivance can
be effected through the rotation of the metallic body 1 by the "screwing in" or
screwing out" of the two hooks, the application of the whole contrivance being
effected by hanging the heald shaft 6, which is under the influence of the downward
tension of the spring 7, on the shaft regulators suspended in pairs to the upper
shaft belt or strap, for the purpose of enabling the heald shaft to be adjusted and
fixed at any desired height or depth by the rotating of the metallic part 1 in the
one or other direction.
;
2. The improved apparatus for adjusting the heald shafts in weaving looms
substantially as described with reference to the drawings.
