PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Cloth used for Press Sheets,
Filtering Sheets, and other similar purposes.
We Sir ELKANAH ARMITAGE AND SONS LIMITED, Manufacturers and PHILIP
Dunkerley, Manager, all of Pendleton near Manchester in the County of
Lancaster do hereby declare the nature of this invention to be as follows :-
This invention relates to the manufacture of cloth used for press sheets and
filtering sheets employed in the manufacture of porcelain and for other similar
purposes, and the object of the invention is to strengthen the cloth very materially
at the centre where the tube is attached to the sheet or at any other part which is
subjected to great strain or pressure.
This additional strength is usually obtained by doubling and stitching the cloth
together along the middle and by further sewing on a patch of the same cloth at the
point where the tube is attached.
This invention consists principally in giving increased strength to such portion or
section of the cloth first by weaving this portion of the cloth with double_the
amount of weft, and secondly by inserting in that part of the shed by hand or
otherwise during the process of weaving, a special strengthening cord at any given
interval, so that this portion of the cloth is very considerably stronger than any
other portion.
Instead of weaving the cloth with double the amount of weft at the part required
the same effect may be produced by the use of double warp or by using both double
warp and double weft at this part, and the strengthening cords may be inserted at
intervals either in the form of warp instead of, or, as well as weft if preferred, or
metallic wires may be used at intervals instead of the strengthening cords above
mentioned.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Cloth used for Press Sheets,
Filtering Sheets, and other similar purposes.
We Sir ELKANAH ARMITAGE AND SONS LIMITED, Manufacturers, and PHILIP
DUNKERLEY Manager all of Pendleton near Manchester in the County of
Lancaster, 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 relates to the manufacture of cloth used for press sheets and
filtering sheets employed in the manufacture of porcelain and for other similar
purposes and the object of the invention is to strengthen the cloth very materially
at the centre where the tube is attached to the sheet, or at any other part which is
subjected to great strain or pressure.
This additional strength is usually obtained by doubling and stitching the cloth
together along the middle, and by further sewing on a patch of the same cloth at the
point where the tube is attached.
This invention consists principally in giving increased strength to such portion or
section of the cloth first by weaving this portion of the cloth with a greater
amount of weft, and secondly by inserting in that part of the shed, by hand or

page_text: otherwise, during the process of weaving a special strengthening cord at any given
interval so that this portion of the cloth is very considerably stronger than any
other portion.
Instead of weaving the cloth with a greater amount of weft at the part required
the same effect may be produced by the use of more warp or by using both more
warp and more weft at this part, and the strengthening cords may be inserted at
intervals either in the form of warp instead of or as well as weft if preferred, or
metallic wires may be used at intervals instead of the strengthening cords above
mentioned.
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 :-
The manufacture of cloth (for the purposes above described) portions or sections
of which are woven with more than the ordinary amount of warp or weft or both
and provided at intervals with strengthening cords or wires such strengthening
being either by way of warp or weft or both substantially as hereinbefore
described.
