The disclosure embraces a centrifugal casting apparatus of a character for casting comparatively small articles or objects of highly refractory metals, such as jewelry and similar articles, the centrifugal casting apparatus being enclosed in a housing, the arrangement having a motor-driven throwing arm and a secondary arm mounting components of the casting apparatus, the secondary arm being adapted upon energization of the motor to be centrifugally oscillated or rotated about a pivot axis to a diametrically aligned position with the throwing arm to rapidly accelerate flow of the molten casting metal into the mold, the apparatus including a closure or cover for the housing in association with means for automatically interrupting operation of the motor when the cover or closure is moved to an open position.
