page_text: We, EWALD WINDRATH & WILHELM HAUSMANN owners of the firm of Windrath
and Hausmann of Barmen, Rhenish Prussia, Germany Ribbon Manufacturers 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 object of this invention is to improve the reeds or slays for looms in such a
manner, that they divide the warp threads, when going backwards with the batten, at
different intervals of time.
The qualities required until now of a good reed are, besides equal pitch or equal
distance of the splits or dents from each other, that the edges of the splits should form
an even surface on the front side as well as on the back side, that is to say that all
splits are exactly of same breadth throughout, and that all are set exactly in one
line.
These conditions are only neglected or altered purposely for the front or beating
side of the reed in that case where it is intended to produce a stuff having the
weft threads lying in wave lines, as is sometimes the case with certain gauze like
articles.
But the splits or dents of these reeds are also uniform and equal in breadth
throughout.
There is however no difference in the working of these two sorts of reeds with splits
of equal breadth with regard to the division of the warp threads, whether they form
an even and plain, or a wavy surface in front and back of the reed.
Now the equal or simultaneous division of the threads when the slay goes backwards
causes much friction between the splits and the yarn and if this is of somewhat
inferior quality it is easily torn.
If however the splits of a reed, of whatever material they may be, are made of
unequal breadth and if they are bound together to form a complete reed in such a
manner, that the edges of the front side form one even and uniform surface, whereas
the back side is made very uneven, the broader dents projecting more than the narrow
ones at the back side, a reed so made will divide the warp threads at different
DE21

page_text: moments; much less friction will be caused and the yarn will thus be more spared.
Unequalities of the threads can pass easier between the splits and the consequence is,
that a finer quality of goods will be produced, or by using yarn of inferior quality a
stuff can be made having as good an appearance as if best yarns had been employed
for the warp..
In describing in the following the new reed reference is made to the accom-
panying drawing, in which, for the sake of clearness, a reed of wide pitch is
represented.

The new reed is made in the ordinary manner, by binding the single splits together
by means of wire or by soldering them together, care being taken to distribute the
splits in such a manner that the back side shall present as uneven a surface as
possible.
The horizontal rods A A and B B between which the splits are set are of a length
corresponding to the width of the loom or to the breadth of the stuff to be woven
respectively, and their vertical distance corresponds to the height of the shed as usual,
-but-as_will_be_seen from figure 2, the breadth of the splits themselves varies very
much. There is no special order to be observed in-setting_the_splits but, that
never two of equal width shall come side by side. The greater the variety, the better
the reed will act and divide the warp threads at separate intervals.
The new reed is to be mounted in the loom in such a manner that the even or
beating side will come to the front and the uneven side to the back.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
"A reed or slay for looms dividing the warp threads at different intervals of time on
its backward motion, by being made of splits or dents of different breadths and which
are so fixed and bound together to form the complete reed, that their front edges lie all
in one and the same plane and make an even surface, whereas the back side is as
unequal as possible."
