IMPROVEMENTS IN THE PROCESS OF PLATING IRON, STEEL, COPPER, AND THE ALLOYS OF THE LATTER WITH NICKEL, COBALT, AND THEIR ALLOYS
Year: 1880

page_text: LETTERS PATENT to Fredrich Carl Glaser, of Berlin, in the Kingdom of
Prussia and Empire of Germany, Engineer and Patent Solicitor, for an
Invention of "IMPROVEMENTS IN THE PROCESS OF PLATING IRON, STEEL,
COPPER, AND THE ALLOYS OF THE LATTER WITH NICKEL, COBALT, AND
THEIR ALLOYS." A communication by Theodor Fleitmann, of Iserlohn,
Prussia, Germany.
PROVISIONAL SPECIFICATION left by the said Friedrich Carl Glaser at
the Office of the Commissioners of Patents on the 24th July 1880.
FREDRICH CARL GLASER, of Berlin, in the Kingdom of Prussia and Empire of
Germany, Engineer and Patent Solicitor. "IMPROVEMENTS IN THE PROCESS OF
PLATING IRON, STEEL, COPPER, AND THE ALLOYS OF THE LATTER WITH NICKEL,
COBALT, AND THEIR ALLOYS." A communication by Theodor Fleitmann, of
Iserlohn, Prussia, Germany.
The inventor of the process described in the Specification of Letters Patent,
No. 5127, A.D. 1878, has found by further experiments that the said process is
also applicable to nickel containing iron or zinc, the quantity of iron in the alloy
amounting up to 50 per cent. These alloys of nickel and iron, like pure nickel, are
not liable to oxidation, but preferable to the latter where cheapness is an important
consideration. Iron and steel may also be plated in a similar manner with alloys
of copper and nickel in various proportions.
The principal condition for this mode of plating is the complete exclusion of air
from the surfaces to be welded, which may be effected in various manners, but
preferably by wrapping the metals to be united with thin metal sheets, exposing
them to the required beat, and uniting them afterwards by the hammer or by
rolling, the metal sheets used as wrappers being subsequently removed from the
product by chemicals or in any other suitable manner. Thin sheet iron is a suitable
packing material, as it can be easily removed by diluted sulphuric or muriatic acid.
By this process various sorts of sheet metal and wire may be produced, which are
applicable to numerous industrial purposes.

the said Friedrich Carl Glaser in the Great Seal Patent Office on the 24th
January 1881.
FRIEDRICH CARL GLASER, of Berlin, in the Kingdom of Prussia and Empire of
Gerinany, Engineer and Patent Solicitor. "IMPROVEMENTS IN THE PROCESS OF
PLATING IRON, STEEL, COPPER, AND THE ALLOYS OF THE LATTER WITH NICKEL,
COBALT, AND THEIR ALLOYS." A communication by Theodor Fleitmann, of
Iserlohn, Prussia, Germany.
A process of plating metals with nickel is already described in the Specification
of Letters Patent, No. 5127, A.D. 1878.
The inventor of the said process has found by further experiments that it is also
applicable to alloys of nickel with zinc or iron, and that the quantity of iron in
the iron alloy may amount up to 50 per cent. Such alloys of nickel and iron are,
like pure nickel, not liable to oxidation, and therefore preferable to the latter
where the price of the product must be considered. Iron and steel may likewise
be plated by welding with the alloys of copper and nickel in various proportions.
The principal condition for all these welding processes is the complete exclusion
of air from the surfaces to be welded. This exclusion of air can be attained in
various ways, for instance, by wrapping with thin metal sheets the metals to be
united, exposing them to the required heat, and uniting them afterwards by the
hammer or by rolling. The metal sheets used as wrappers, and thus likewise
subjected to the welding process, are removed from the product by chemicals, or in
any other suitable manner, after the welding has been completed and the sheets
have been partly rolled out.
Thin sheet iron is a specially suitable packing material, because it can be easily
removed by diluted sulphuric or muriatic acid.
The exclusion of air may however be obtained by any other of the ordinary
methods.
By the process described numerous sorts of sheet metal and of wire may be
produced which are applicable for a variety of industrial purposes. The nickel
plated alloy of copper and nickel, before mentioned, has the advantage over nickel
plated sheet iron, that in case of exposure of the copper-nickel at the edge of the
sheet, the production of rust, to which sheet iron is always liable, need not be
apprehended, and the difference of color on the narrow edge is imperceptible.
CLAIMS.
1. The application of the process described in the Specification of my Patent
above mentioned for plating alloys of iron, steel, and nickel with iron and zine
alloys of nickel.
2. The mode of excluding the air preferably applied in this process, and
consisting in wrapping the metals to be welded with thin metal sheets which are
subsequently removed by chemicals.
☐ In witness whereof, I, the said Friedrich Carl Glaser, have hereunto set
my hand and seal, this Twenty first day of January, A.D. 1881.
FRIEDRICH CARL GLASER,
(L.S.)
