Description
On the right is a lake steamer laden with ore from the Lake Superior district. It is at the docks alongside an unloader. This unloader is only a huge steel framework with a number of tracks extending on one side over the dock, and on the other side over the switches. The trucks on these overhead tracks are equipped with buckets which dip the ore out of the hold of the vessel. The bucket is pulled by an engine, up to the truck to which it hooks. This releases the truck, which travels to the other end of its tracks, and there the bucket is lowered and emptied. The view shows one car on the right being loaded. The truck on the left is dumping its bucket of ore into the freight car. Four series of cars can be loaded here at the same time. The hoist, or steel framework, is 60 feet high and 180 feet long. The bucket is of the type called clam shell. The steel cars into which the ore is dumped are shaped inside like hoppers. That is, their bottoms are sloped. When these cars reach the steel mills, the hopper is opened at the bottom and the ore is dropped into bins below the tracks. Each car can carry 50 tons of ore, and on the return journey will carry 38 tons of coal. You will observe lying on blocks of wood on the ground, two pairs of steel cables. Each of these cables is slowly moving. When it is necessary to move the car, or the series of cars, to shift them under the buckets, a chain is attached from the cable to the car. When the car has been brought into the proper position the chain is unhooked. What is meant by the Lake Superior district? Explain briefly how the unloaders work? Where is Conneaut?
