CASTING MACHINES into a pair of bearings on the rims of the circular table, circular girder is fitted with toothed s purpose of revolving the whole ap- paratus. The toothed segments, I which gear with the driving wheels are shown in a, Fig. 232. Figs. 234 and 235 show the machine in plan and ele- The plan also shows the coupled to three shafts, ends of which small spur are keyed which cause the casting vation. engine to the pinions table to revolve in the direction of the arrow. The filling device is shown in Fig. 232. The metal is poured first from a ladle into a chute a, by which it reaches the revolving fill- ing drum B. The latter is driven by spur wheels, and the other side opposite to the drive is supported by three rollers fixed to the bracket c. Both a and b are lined inside with fireclay. The drum B has six radial apertures, and is caused to revolve at exactly the same cir- cumferential velocity as the moulds, so that the six exits are, so to speak, .....................
