Abstract
A casting-marking apparatus is adapted for incorporation in a permanent foundry pattern of the type used to produce sand molds for metal casting. The apparatus carries a marking that is impressed in the sand old and subsequently reproduced on a casting. The apparatus is designed and constructed so that the marking that it carries can be altered from a station remote from the pattern. In the apparatus, the alterable marking is carried by a marking body that is rotated by an air actuated piston.
