The Casting Machine of the Ironworks of the Aplerbecker Hütte. — This machine was built by the Deut- schen Machinen fabrik A. G. The essential features of this machine consist of two compara- tively small turntables placed close together, the outer circum- ferences of which are fitted with tipping moulds for the iron. The liquid metal is led to these turn- tables by an oscillating trough with two side and one end out- lets. This trough receives a rocking motion round its longi- tudinal axis, so that the two side outlets discharge the metal into the receptacles of each table alternately. It will thus be seen that the tables (each of which has 64 moulds on its circum- ference) are stationary during the pouring process, and whilst the mould of one is filled the other table is moved forward presenting a fresh mould to the rocking shoot, which is immediately re- versed and fills it. When the moulds have passed 270°, or three- quarters of a revolution of the table, and the iron has congealed, the moulds are here turned release the pig into an iron wagon underneath. 180° and tapped to The moulds remain in their inverted
