IMPROVEMENTS IN THE MANUFACTURE OF ASBESTO-METALLIC CLOTH
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
We SAMUEL TURNER of Spotland Works Rochdale in the County of Lancaster
and JOHN BELL of 118 Southwark Street London, Asbestos Manufacturers do
hereby declare the nature of the invention for "IMPROVEMENTS IN THE
MANUFACTURE OF ASBESTO-METALLIC CLOTH to be as follows :-
"
The object of our said invention is to manufacture a woven fabric chiefly of
asbestos which shall be firm and close and shall be capable of bearing a greater
tensile strain and resist pressure and heat better than the asbestos cloth as usually
made is capable of.
The invention consists in the manufacture of a cloth by the combination of a fine
hard spun asbestos thread for warp, and a weft composed of fine brass, copper or
other suitable wire; or from a wire warp and a hard spun asbestos thread for weft,
which latter we consider preferable.
The object of combining the wire with the asbestos thread or yarn in the
manufacture of cloth is to obtain a fine firm and close texture of fabric of great
strength for various purposes. For instance it may be used with advantage in
making tight the joints of steam pipes and for packing for the stuffing boxes of
stoam engines and for other similar purposes.
Asbestos fibre possesses the property of resisting the action of heat to a great
extent; but it is lacking in tensile strength, consequently cloth made entirely from
asbestos yarn, though capablo of resisting great heat is liable to give way when
subjected to high pressure, and the introduction of wire in the manner herein set
forth acts as a binder to the asbestos yarn and adds greatly to the strength of the
fabric and its suitability for such and various other purposes.

We SAMUEL TURNER of Spotland Works Rochdale in the County of Lancaster
and JOHN BELL of 118 Southwark Street London, Asbestos Manufacturers do
hereby declare the nature of our invention for "IMPROVEMENTS IN THE
MANUFACTURE OF ASBESTO-METALLIC CLOTH" 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 our said invention is to manufacture a woven fabric principally of
asbestos which shall be firm and close and shall be capable of bearing a greater
tensile strain and resist pressure and heat better than the asbestos cloth as usually
made is capable of.
The invention consists in the manufacture of a cloth by the combination of a fine
hard spun asbestos thread for warp, and a weft composed of fine brass, copper or
other suitable wire, or from a wire warp and a hard spun asbestos thread for weft,
which latter we consider preferable.

strength for various purposes.
•
For instance it may be used with advantage in making tight the joints of steam
pipes, and for packing for the stuffing boxes of steam engines and for other similar
purposes.
Asbestos fibre possesses the property of resisting the action of heat to a great
extent (but it is lacking in tensile strength) consequently cloth made entirely from
asbestos yarn though capable of resisting great heat, is liable to give way when
subjected to high pressure and the introduction of wire in the manner herein set
forth acts as a binder to the asbestos yarn and adds greatly to the strength of the
fabric and its suitability for such and various other purposes.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed I declare that
what we claim is
.
First the manufacture of a cloth by the combination of a fine hard spun asbestos
thread for warp and a weft composed of fine brass copper or other suitable
wire.
Secondly we claim the manufacture of a cloth by the combination of a warp
of fine brass copper or other suitable wire with a weft of hard spun asbestos
thread.
Thirdly we claim as a new article of manufacture the combined asbesto-metallic
cloth woven in the manner herein before described.
