The Mechanical Handling and Storing of Material

COKE FROM COKE OVENS 385 conveyor by additional jets. The sections of the conveyor are made of perforated sheet iron, with side plates 12 in. high. The conveyor consists of three chains connected to each other by cross-pieces, and a narrow gangway for the attendants is provided on either side of the conveyor. The delivery end of the machine is provided with a jigging screen, and the whole is mounted on a substantial frame running on wheels in front of Fig. 545.

The quencher and loader are moved from one oven to another by a slewing crane, operated from the main motor by ropes; and a contrivance with intermittent motion, between the quencher and conveyor, enables the coke to be spread out for completing the quenching. Another somewhat different type is the Düsseldorf, used at the Herne cokery of the Hüstener Gewerkschaft (Fig. 546). In front of the short ramp a, and about 6 ft. lower, is a second broader level b, with the rail track for the machine. The apparatus, like those formerly described, is self-contained; the floor, as it were, of the machine consists of a grating c, the bars of which are attached to two frames in such a way that those secured to the frame c can alternately be raised and lowered by means of a roller f whilst the intermediate bars remain stationary. The screen is operated by eccentric shafts d and on which the screen frames are loosely mounted in guides V. On the side away from the ovens the screen has a machine of Kellner & Flottmann, of Fig. 546.

The screenings fall into the hoppered bunkers of perforated plate in the underbody of the carriage, so as to allow the quenching water to escape. The quenching water is drawn from a conduit h below the track through a suction pipe i by means of a centrifugal pump, which delivers the water to a series of sprinkling pipes k above the screen. The machine deals in each operation with the whole charge of one
