The Mechanical Handling and Storing of Material

COKE FROM COKE OVENS 381 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 Fig. 538. The Moore Quenching and Loading Machine. 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
