NOW KNOW YE, that we, the said Clement Rostaing and Elie Vivet,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement :-

page_text: This Invention has for its object an improved material suitable for
making steam, water, and gas tight joints, and for similar uses. We
take two sheets of wire cloth of any suitable dimensions, and metal such
as iron, copper, or brass; we place between them a sheet of lead, and
pass them together through rollers so as to press the wire cloth into the
substance of the lead, and thus form of the whole one and the same body.
Other suitable means may be resorted to for combining the wire cloth
and the lead.
The material thus made is placed and pressed between the parts of
junction of any apparatus for sustaining pressure, such as steam, liquid,
or gas pressure, and for preventing the egress or ingress of such steam,
liquid, or gas.
Having thus described the nature of our Invention, and the manner
of performing the same, what we claim is, the interposition of a sheet
of lead between two sheets of metallic cloth for the production of an
improved material for making steam, water, and gas tight joints, and for
other similar uses.
In witness whereof, we, the said Clement Rostaing and Elic Vivet,
have hereto set our hands and seals, this First day December,
in the year of our Lord One thousand eight hundred and sixty-
eight.
