To the new converter, on tire other
hand, the blast is over the edge of the iron,
horizontally, and produces rotary mo-

agitation. which presents every portion Of
I the metal to the blast, and at the same
time blows the Stag and other impurities
which are floating on the surface to the
l farther side of the converter.
IL will be seen that this converter is
simply a mechanical means Of doing ex-
actly what the puddler does by hand,
turning the iron over snd over, and pre-
renting Oh parts of the molten mass 70 the

hitherto been used in the practical me-
chanical arts. In the materials Of It's man

ipulation. the new converter has the same
essential necessities al the old.
Since the metal which comes from the
Robert converter can be a pure iron, low
or mild steel. or steel high IN carbon,
from this converter can be poured every
Grade of metal that IS used by the smith
or rolling mill. Since the bias, Of

as In the Bessemer process, the
blast ia vastly less, and the entire plant,
including engines and al necessary ma
chinery for the production Of 100 tons a
day of any grade OF iron or steel, can be
built for less than SIC, 900, or One-ihird the
cost of the Bsssemer plant Of the same ca

The Besssmer converted must be refined /
after very few blasts, the Robert after
1 600 blasts. By the new process the
metal is heated much hotter than by the
Bsssemer process, and is therefore much
more luid but this quality, added to
the freedom from Impurities, enables
the new converter to pour the metal d.
rectly into the billet which Is to be
rolled INTO the desired form, whereas the
Bessemer product ia so impure that 1t Is

broken down. as il is called, being
rolled through a succession Of rolls which
