Improvements in or relating to Cloths for Oil-presses, Filter-
presses, and the like.
A communication from HENDRIK WILLEM JAN VAN OTTERBEEK BASTIAANS,
of Thiergartenstrasse 31, Cleve, Germany, Technologist.
I, ALFRED JULIUS BOULT, of 111 Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
The present invention relates to fabrics, used in the compression of oilseeds and
the like, the purpose being to make such fabrics durable. It has been found that
the fabrics hitherto used usually became worn out only in certain places, while
other places were little or not at all worn. To avoid this drawback, the fabrics,
used in pressing are made, according to the present invention, so as to form an
endless woven or equivalent fabric. When manufacturing such fabrics, it is
therefore the best to manufacture at first a hose pipe and to cut it into pieces; the
hose pipe can be of any material and is, when used, placed flat. After each
operation of pressing or after a number of such operations, the hose pipe, when
again folded together, has the parts of its opposed sides in new relative positions,
and like changes enable the whole width of the fabric to be worn evenly. These
fabrics are therefore much stronger, than those hitherto used.

1, ALFRED JULIUS BOULT, of 111 Hatton Garden in the County of Middlesex,
Chartered Patent Agent, 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 fabrics, used in the compression of oilseeds and
the like, the purpose being to make such fabrics durable. It has been found that
the fabrics hitherto used usually became worn out only in certain places, while other
places were little or not at all worn. To avoid this drawback, the fabrics, used in

page_text: compressing are made according to the present invention so as to form an endless
woven or equivalent fabric. When manufacturing such fabrics it is therefore best
to manufacture it at first in the form of a tube or hosepipe and to cut it into
sections; the tube can be of any material and is, when used placed flat.
After each operation of pressing or after a number of such operations the tube
when again folded together has the parts of its opposed sides in new relative
positions, and like changes enable the whole width of the fabric to be worn evenly.
These fabrics are therefore much more durable than those hitherto used.
In the accompanying drawing,
Figure 1 is a cross section of a fabric according to the present invention.
Figure 2 a cross section of two such fabrics, the material to be compressed being
enclosed between them.
Figure 3 is a plan.
The fabrics used in compression may be used either as ordinary flat fabrics, or as,
shown in Figure 2 their ends may be thickened by folding them. After the fabrics
so formed have been used for a certain time, they are folded anew that is to say so
as to cause another part of the fabric to form the thickened edge.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondent and in what manner
the same is to be performed I declare that what I claim is :-
1. Flattened tubular fabrics or cloths for use in filter presses and the like as and
for the purpose described.
2. Fabrics or cloths for use in oil-presses, filter-presses and the like, consisting of
two pieces of flattened tubular fabric having folded or thickened edges between
which fabrics the material to be treated is placed, substantially as described.
