COKE FROM COKE OVENS

from driver’s cab tn serve for the travelling gear of the loader and for the manipulation
of the receptacle. When the latter is filled with the contents of an oven, and after the
coke is quenched, it is lifted approximately horizontally by means of the ropes, and
carried by the crane to the empty truck, where the coke is emptied by tilting as shown in
the illustration. The apparatus has answered well, and the amount of wear is small,
the only drawback being that the coke is not screened. Hence the device is restricted
to works where the coke is consumed on the premises.
At the Lebanon Works of the same company is a similar installation at work for two
batteries of 232 ovens, for which also two each of four receptacles are in use. In these
installations the appearance of the coke is of less importance, but the loading apparatus
of Moore, Philadelphia, effects the quenching and handling of the coke in a more careful
manner, the air being excluded, and a silvery coke, resembling that from beehive ovens, is

obtained. The device consists of an iron chamber as large as a coke oven, which is
mounted on a travelling carriage operated by electricity (see Fig. 538). The chamber is
enclosed in a shell divided into several vertical compartments a, with a short chimney
b at the forward end, provided with a throttle valve c, the space between the compartment
and shell being partly used as a water jacket. Strong doors at each end can be operated
from the driver’s stand d, the two sections of these double doors being opened and closed
by ropes and pulleys e. An open slit is left under the front door for the escape of the
surplus quenching water through a gutter f into the drain g. The coke falls down a
chute h into the railway truck. The two halves of the door next the oven fit against the
oven door frames i when open. A lever k raises a small flap from the bottom of the
chamber, to make a joint with the oven, and prevent the escape of water at that end; the
flap is balanced by the weight I. The quenching water is introduced from the hydrants
by a hose connected with a pipe on the machine frame.
The working of the apparatus is illustrated in Fig. 539, in which a is the battery of
