Firm of J. Brandt and G. W. v. Nawrocki, Patent Solicitor and Civil Engineer,
of 124, Leipzigerstrasse, Berlin, Germany, for an Invention of "A NEW OR

GERARD WENZESLAUS VON NAWROCKI, Proprietor of the Firm of J. Brandt
and G. W. v. Nawrocki, Patent Solicitor and Civil Engineer, of 124, Leipziger-
strasse, Berlin, Germany. A NEW OR IMPROVED METALLIC FABRIC." (A com-
munication from Messieurs Schütz and Juel, in Wurzen, in the German
Empire.)
This Invention refers to the manufacture of a new metallic textile fabric with
or without pressing and imprinting of patterns. The mode of manufacturing this.
material is as follows:-The metal intended to be used is rendered into small
particles, short or long according to requirements, and mixed with a sticky material,
such as india rubber; this mixture is then by hand or otherwise transferred to the
backing or fabric, consisting of, say, cotton, wool, linen, silk, or half silk; the fabric
is then dried and calendered or pressed in any suitable manner, receiving at the
same time a pattern if desired.
The metal cloth thus produced is not stiff, but remains soft. The liquid, sticky
with metal charged mixture, does not penetrate to the underside of the fabric, which
thus remains clean.

GERARD WENZESLAUS VON NAWROCKI, Proprietor of the Firm of J. Brandt
& G. W. v. Nawrocki, Patent Solicitor and Civil Engineer, of 124, Leipziger-
strasse, Berlin, Germany. "A NEW OR IMPROVED METALLIC FABRIC." (A com-
munication from Messieurs Schütz and Juel, in Wurzen, in the German
Empire.)
This Invention refers to the manufacture of a new metallic textile fabric with
or without pressing and imprinting of patterns. The mode of manufacturing this
material is as follows:-The metal intended to be used is rendered into small
particles, short or long according to requirements, and mixed with a sticky material,
such as india-rubber; this mixture is then by hand or otherwise transferred to the
backing or fabric, consisting of, say, cotton, wool, linen, silk, or half silk; the fabric
is then dried and calendered or pressed in any suitable manner, so as to produce a
smooth metallic face, which may also be impressed with a pattern if desired; the
pattern may be produced by embossing or printing.
The metal cloth thus produced is not stiff, but remains soft. The liquid and
sticky mixture charged with metal does not penetrate to the underside of the
fabric, which thus remains clean.
And having thus described and ascertained the nature of this Invention, and in
what manner the same is or may be carried into effect, as communicated to me, I
declare that I claim,―
First. The manufacture of metal cloth by coating a backing of textile fabric with
a mixture of metal rendered into small, short, or long particles, and a suitable
adhesive material, such as india-rubber, the said coating when dry being calendered
or pressed, and if desired impressed with a pattern, as set forth.
Second. As a new article of manufacture, the metal cloth herein described.
In witness whereof, I, the said Gerard Wenzeslaus von Nawrocki, have
hereunto set my hand and seal, this Sixth day of January, in the year of
our Lord One thousand eight hundred and eighty-two.
