The Mechanical Handling and Storing of Material

45§ THE MECHANICAL HANDLING OF MATERIAL band conveyor, carried on a gantry, which afterwards discharges through a suitable spout into the mill. I he electric current is conducted along the face of the warehouse wall, which is fitted with a number of wall plugs, from any of which a connection can be made by flexible cable to the motor. Barge Elevators of Unruh & Liebig.—The installation illustrated in Figs. 637 and 638 consists of two elevators mounted on a movable carriage with steam engine and boiler. One of the elevators is a fixture, whilst the other is suspended from the jib end of a derrick, and can thus be lowered into the hold. There is a conveyor between the delivery end of one and the feed end of the other elevator, so Fig. 635. Carrier receiving Bananas in Hold of Vessel. Fig. 636. Carrier depositing the Fruit on Deck. that no matter in what position the movable elevator stands the material is conveyed from one to the other. I he fixed elevator delivers into the hopper, so that the grain, etc., can be filled in sacks before it is loaded into the railway trucks. The illustration here given is a front elevation and side view of the design of Messrs Unruh & Liebig, Leipzig. A similar installation by the same designers is shown in Fig. 639. This is rather more compact, but is only suitable for quay sides where no attention need be paid to the varying tides. It is driven by an electro-motor, the cable which supplies the current being concealed in a leather tube so as to allow the truck the necessary latitude in its movements on the quay. The hopper which receives the grain is fitted with an automatic weighing machine. Barge Elevator at a Copenhagen Flour Mill.—This installation, also erected
