Year: 1881

page_text: LETTERS PATENT to William Morgan-Brown, Patent Agent, of 38, Southampton
Buildings, London, for an Invention of "IMPROVEMENTS IN THE MANU-
FACTURE OF GALVANO-NICKEL-PLATED SHEET IRON, SHEET ZINC, AND TIN
PLATE" A communication from abroad by Ehregott Schroeder, of Leipzic,
Saxony.
PROVISIONAL SPECIFICATION left by the said William Morgan-Brown at
the Office of the Commissioners of Patents on the 18th November 1881.
WILLIAM MORGAN-BROWN, Patent Agent, of 38, Southampton Buildings, London.
"IMPROVEMENTS IN THE MANUFACTURE OF GALVANO-NICKEL-PLATED SHEET IRON,
SHEET ZINC, AND TIN PLATE." [A communication from abroad by Ehregott
Schroeder, of Leipzic, Saxony.]
To produce nickel-plated sheet-metal the expensive German silver has been used
up to the present time, the cheaper metals, as zinc, tin-plate, or others, did not
answer the purpose. Lately iron-plate has been used successfully, but the process
of plating iron with nickel can be done only under welding heat.
The new process described hereafter admits of the application of the cheaper
metals, as iron, zinc, or tin, for nickel-plating in the most simple manner.
I clean the sheet-iron, sheet zinc, or tin plate by dipping in acids, grinding and
polishing, and then galvanise them directly with nickel of 10 thickness
without having deposited before the ordinary covering of copper. Then I pass
the sheets between the rollers of a rolling mill to equalize the thickness and to
give the sheet a beautiful polish. In treating tin plate in this manner it may be
rolled before and after the nickel-plating, whereby I obtain a surface with a still
better and more durable polish.

"IMPROVEMENTS IN THE MANUFACTURE OF GALVANO-NICKEL-PLATED SHEET IRON,

To produce nickel plated sheet metal the expensive German silver has been used
up to the present time, the cheaper metals, as zinc, tin plate, or others did not

Lately iron plate has been used successfully, but the process of plating iron with
nickel can be done only under welding heat.
My new process described hereafter admits of the application of the cheaper
metals, as iron, zinc, or tin, for nickel plating in the most simple manner.
I clean the sheet iron, sheet zinc, or tin plate by dipping in acids, grinding,
and polishing, and then galvanize them directly with nickel of 1/10 millimetre
thickness without having before deposited the ordinary skin of copper. Then I
pass the sheets between the rollers of a rolling mill to equalize the thickness and
to give the shect a beautiful polish or surface. In treating tin plate in this
manner it may be rolled before and after the nickel plating, whereby I obtain a
surface with a still better and more durable polish.
Having thus described and particularly set forth the nature of the said Invention
and the manner of carrying the same into effect, I would have it understood that
what I claim is,-
The process of manufacturing nickel plated sheet metal, consisting in rolling the
sheet zinc, sheet iron, or tin plate to an equal thickness after having deposited a film
or cont of nickel of 1/10 millimetre thickness direct on the cleaned surface without
the ordinary coat of copper and without the use of any welding powder or any
aunealing process, substantially as and for the purpose specified.
In witness whereof, I, the said William Morgan-Brown, have hereunto set
iny hand and seal, this Thirteenth day of May, in the year of our Lord One
thousand eight hundred and eighty two.
