38o THE MECHANICAL HANDLING OF MATERIAL
Another class of loading machine dispenses with the coke ramp altogether. Such
machines are exposed to heavy wear and tear, not only from the coke itself, but also
from the great heat and the corrosion from the acid vapours, so that their construction
is connected with many difficulties. As steel or wrought iron cannot resist these

conditions, cast iron is used as much as possible in the building of these machines,
and especially for parts where the extra weight is of less consequence.
A machine of such a type was supplied about 1900 by the Wellman-Seaver Co.

at Buffalo, U.S.A., to serve ten batteries
with 940 ovens (Fig. 537). Two longitu-
dinal walls are built in front of the ovens,
and on these are placed open sheet-iron
receptacles a (two for each battery) con-
nected with the ovens by a platform b.
Each receptacle holds a charge of coke,
which is quenched from the platform, the
surplus water draining away through the
perforated bottoms into a gutter between
the two walls, and through drain c. The
track for the coke trucks is beyond the
outer wall, and is served by a portable
crane, provided with a running head d for
