The Mechanical Handling and Storing of Material

COKE FROM COKE OVENS 365 of a coke fork, lift the coke on to the conveyor whilst the machine slowly advances (see Fig. 506). A well-designed form of conveyor for coke ovens is the work of Mr Joseph Müller, of the Matthias Colliery, at Essen, in Germany. This appliance is intended to take the coke as it comes from the ovens in a red-hot state and at once quench it in water, to allow it to dry and be discharged on a sieve or grate, and finally to load it into wagons or boats in one continuous and automatic operation. A diagrammatic view of the apparatus by which this is accomplished is shown in Fig. 507. In front of the outlets of the coke ovens there is a tank b, which is kept full of water. The right end of the tank has a sloping side. In this tank is placed the carrier and conveyor, which consists of a strong frame on wheels which runs on three transverse rails, allowing the whole apparatus to be moved crosswise in the tank. Strong side beams of plates and bars form the frame of the carrier. Cross-bars and stays serve to strengthen it laterally. That part of the carrier frame near the oven is built horizontally, and is completely immersed in the water. The other part rises gradually, and as its further end is entirely out of the water and so high that there is sufficient room below it for a sieve or grating at s, which may be built in one with the carrier, or may form a separate part of the apparatus. The sieve or grating may be made with movable bars, or the latter may be fixtures. When arranged separately from the transporter frame, the sieve may run across the whole width of the tank. The carrier band consists of two chains, one at the right and the other at the left edge. They are connected laterally by means of bolts, which bolts form at the same
