Year: 1881

page_text: LETTERS PATENT to Raphael Hunter Brandon, of No. 1, Rue Laffitte, Paris,
in the Republic of France, Engineer and Patent Agent, for an Invention
of "IMPROVEMENTS IN WIRE GAUZE EMPLOYED IN PAPER MILLS AND FOR
SIFTING PURPOSES." A communication by Louis Lang and Son, of Alsace-
Lorraine, in the Empire of Gerinany, Wire Gauze Manufacturers.
PROVISIONAL SPECIFICATION left by tho said Raphael Hunter Brandon
at the Office of the Commissioners of Patents on the 15th June 1881.
RAPHAEL HUNTER BRANDON, of No. 1 Rue Laffitte, Paris, in the Republic of
France, Engineer and Patent Agent. “ImprovemeNTS IN WIRE GAUZE EMPLOYED
IN PAPER MILLS AND FOR SIFTING PURPOSES." A communication by Louis Lang
& Son, of Alsace-Lorraine, in the Empire of Germany, Wire Gauzo Manufacturers.
Hitherto the wire cloths for the manufacture of continuous paper, as well as laid
rollers, wove rollers, & others, as well as for other purposes, have been made of
brass or copper wire, but their continual contact with the paper pulp that
generally still contains chlorine in small quantities as well as other chemicals
causes them to deteriorato slowly.
In order to overcome this difficulty & that the cloths may last longer under the
said circumstances, I coat the wire with nickel, either before weaving the gauze or
after the gauze is withdrawn from the looin.
In the first case, the wire is wound on a bobbin & immersed in a bath of nickel,
whilst at the same time it is acted on by an electric current; in a short space of
time the wire is covered with a coating of nickel sufficient to protect it against the
obnoxious effect of such chemicals that remain in the paper-pulp; this same wire
is then unwound, rewound on another bobbin, and reimmersed in the bath under
the influence of an electric current, for the purpose of conting such parts of the
wire which were previously in contact with the first bobbin.
In the second case, I avoid this double operation by applying the coating of
nickel on the woven tissue, either on its entire length as it leaves the loom, or in
the shape of detached pieces thereof. For this purpose the woven tissue is first
immersed in a pickle bath, and then in the nickel bath; on leaving the latter it is
placed in a hot air chamber, & when completely dry it can be rolled up again ready
for use.

RAPHAEL HUNTER BRANDON, of No. 1, Rue Laffitte, Paris, in the Republic of
France, Engineer and Patent Agent. "IMPROVEMENTS IN WIRE Gauze EmpLOYED
IN PAPER-MILLS AND FOR SIFTING PURPOSES." A communication from Louis Lang

which were previously in contact with the first bobbin.
In the second case, I avoid this double operation by applying the coating of
nickel on the woven tissue, either on its entire length as it leaves the loom, or in
the shaft of detached pieces thereof. For this purpose the woven tissu is first
immersed in a pickle bath, and then in the nickel bath; on leaving the latter it
is placed in a hot air chamber, and when completely dry it can be rolled up again
ready for use.
Having thus described the said Invention as well as the manner in which it is
to be carried into practice, I claim,-
Nickeling wire, as above described, with reference to the first above mentioned
process, and also wire cloth, as above described with reference to the second above
mentioned process for the manufacture of continuous paper, as well as laid rollers,
wove rollers, and others, as well as for other purposes, substantially for the
purposes set forth.
In witness whereof, I have hereunto set my hand and seal, this Fifteenth
day of November, in the year of our Lord One thousand eight hundred and
eighty one.
