Year: 1880

page_text: LETTERS PATENT to William Robert Lake, of the Firm of Haseltine, Lake,
& Co., Patent Agents, Southampton Buildings, London, for an Invention of
"IMPROVEMENTS IN THE MANUFACTURE OF SPOONS AND FORKS." A com-
munication from abroad by Wilhelm Conraetz and Eduard Zwierzina, of
Vienna, in the Empire of Austria.
PROVISIONAL SPECIFICATION left by the said William Robert Lake at the
Office of the Commissioners of Patents on the 7th April 1880.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN THE MANUFACTURE OF
SPOONS AND FORKS." [A communication from abroad by Wilhelm Conraetz and
Eduard Zwierzina, of Vienna, in the Empire of Austria.]
The present improvements in the manufacture of spoons and forks consist in
making the same of malleable cast-iron.
Hitherto in the manufacture of spoons and forks the same have been stamped
from metal blanks.
According to the present improvements the spoons or forks are made of cast-
iron, cast in moulds of metal, or clay, or sand. These iron castings are then con-
verted into malleable cast-iron according to any of the well known processes for
converting ordinary iron castings into malleable cast-iron. The spoons and forks
produced by this method are thereupon ground bright or polished, and afterwards
stamped in dies; and, finally, to protect them from oxidation, are coated with tin,
or nickel, or silver, or similar metals, by any of the ordinary well known processes
for coating articles with metals.

foreign correspondents, and the manner of performing the saine, I wish it understood
that I claim,
First. The manufacture of spoons or forks of malleable cast iron, substantially as
