CASTING MACHINES

All the movements are actuated by hydraulic machinery. The turntables revolve by
means of an oscillating pawl engaging a toothed wheel.
Should any hitch occur to either of the turntables during the pouring of the metal,
the driver of the machine can set the pouring trough into a middle position and discharge
the metal by the end shoot already mentioned and let it run into an emergency pig bed
beyond the two turntables, so that the rest of the iron in the pouring pot can be
disposed of.
A machine on the same principle has since been built by this firm for the
Westphalian Iron Works which is reported to be a success, the only difference being
that hydraulic power has been discarded in favour of electricity.
