Improvements in Battens for Weaving Looms.
1, JOHN POYSER, of Bolehill, Wirksworth, in the County of Derby, Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to battens for weaving looms, and chiefly to battens of the
kind described in the Specifications of former Letters Patent granted to me, viz.,
No: 15431 of 1893 and No. 144 of 1895.
According to my present invention instead of arranging the reeds or teeth of the
batten parallel with each other as heretofore I dispose them radially to correspond
with the radiation of the warp threads in such a manner that when the upper
threads are entering the batten, or when (in the case of a batteu having two parts)
the two parts of the batten coincide as described in the before mentioned specifi-
cations and the warps are passing from the upper part to the lower or vice versa
under the action of the heddles, each reed in its depth from front to back is
approximately parallel with the adjacent warps on either side..

I, JOHN POYSER, of Bolehill, Wirksworth, in the County of Derby, Engineer,
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 :-
My invention relates to battens for weaving looms, and chiefly to battens of the
kind described in the Specifications of former Letters Patent granted to me, viz.,
No. 15431 of 1893 and No. 144 of 1895.
In such battens as heretofore constructed the plates forming the reeds or dents
of the batten are arranged so that the spaces between the several reeds are in
alignment with the warp threads in the fabric, from which it has followed that
when the warp threads between the heddles and the fell of the fabric converge (as
they advantageously may) some of the warp threads, especially those towards
the outsides of the batten, tend to pull against the sides of the reed plates with
the result that sometimes the said threads will slip out from between the said
plates.
The object of my invention is to overcome this liability and to this end instead
of arranging the reeds or dents of the batten parallel with each other as heretofore,
1 dispose them radially to correspond with the convergence of the warp threads in
such a manner that when the batten lies against the fell of the fabric and the upper
threads are entering the batten, or (in the case of a batten having two parts) the

page_text: two parts of the batten coincide as described in the before mentioned specifications
and the warps are passing from the upper part to the lower or vice versa under
the action of the heddles, each reed in its depth from- front to back lies throughout
its length midway between the adjacent warps on each side.
My invention will be readily understood by reference to the accompanying
drawing, in which :-
Figure 1 is a sectional elevation of a batten having two movable parts arranged
to co-operate as described in the Specification of my former Patent No. 14485
together with the feed rollers and the heddles:
Figure 2 is a sectional plan view of the parts shewn in Figure 1 shewing how
the reeds of the batten are arranged radially; and,
Figure 3 is a sectional plan of the lower part of the batten, the warp threads
between the reeds. being omitted:
Figure 4 is a view shewing how the warp threads pass through the batten when
the reeds are in alignment with the warp threads in the fabric.
By referring to these several figures in which a is the batten having the
reeds b, b, c, c the warps, d, d the heddles and e,e the feed rollers, it will be readily
understood how, by making the spaces between the several reeds b, 6 of the batten a
in alignment with the converging warp threads c, e instead of in alignment with the
woven warps, the pressure of the said threads against the sides of the reeds b, b
as shewn in Figure 4, is prevented, thereby obviating the liability of the warps to
escape from between the reeds.
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 batten for looms constructed with the several plates forming the reeds or
dents arranged radially so that each reed in its. depth from front to back lies
throughout its length midway between the converging and adjacent warps on each
side, substantially as described.
