COMPLETE SPECIFICATION filed by the said Alfred Louis Stanislas Chienot

TO ALL TO WHOM THESE PRESENTS SHALL COME, WC, ALFRED
LOUIS STANISLAS CHENOT, and EUGÈNE CHARLES ADRIEN CHENOT, of Clichy-la-
Garenne, near Paris,-(Empire of France,) Chemists, send greeting..
WHEREAS we are in possession of an Invention for "A METHOD OF
EXTRACTING, ELIMINATING, EXTRANEOUS SUBSTANCES FROM STEEL SPONGES," and
have petitioned Her Majesty to grant unto us, our executors, administrators,
and assigns, Her Royal Letters Patent for the same, and have made solemn
declaration that we are the first and true Inventors thereof.

page_text: NOW KNOW YE, that we, the said Alfred Louis Stanislas Chenot, and
Eugène Charles Adrien Chenot,, do hereby declare that the following Complete
Specification, under our hand and seal, fully describes and ascertains the nature
of the said Invention, and the manner in which, the same is to be performed,
that is to say:-
Our Invention relates to a new method of eliminating extraneous substances
from steel sponges while in a state of fusion. Iron sponges being obtained at
a low temperature without fusion of the ore contain all the extraneous sub-
stances in the latter; these extraneous, substances may.be. eliminated in the
cold state by submitting the sponges (after previous pulverization) to the action
of the electro-sorting machine, which only attracting the metallic particles will
yield, on being melted, very pure unalloyed metal. However, in certain cases,
for very rich ores; for instance, it may prove beneficial to adopt, instead of the
sorting machine above alluded to, another process, for which we make the
present application for Letters Patent.
This novel method or process consists in separating, by mechanical power,
the extraneous substances, which owing to their little density will float on the
surface of the melted steel. We obtain this result by throwing into the cru-
cible previous to the spray a quantity of sand; pounded-bricks, or other refractory
substances. This additional matter is thrown in order to cool the dross and
bring it to a certain degree of consistency, that it may afterwards be skimmed
off by means of a spattle.
Having thus described the nature of our Invention, and the manner in which
the same is or may be carried into.effect, we wish.it to be distinctly understood
that we do not confine ourselves to the precise details herein specified, as such
may be varied or modified without, departing from the, principle of action
thereof; but we claim as new, and of our Invention, extracting from steel
sponges extraneous substances by application of the means above specified.
In witness whereof, we, the said Alfred Louis Stanislas Chenot, and
Eugène Charles Adrien Chenot,, have hereunto, set our hand and seal,
this, 4th, day of July, in the year of our Lord. One thousand eight
i
hundred and fifty-six.
