Abstract: An automatic coating system for making set-up by coating a wax pattern with a refractory material, for use in a lost wax process. The system has a set-up pickup device adapted to pickup the set-ups by one from a set-up pool, a slurry dipping device for dipping the set-up in the slurry of the refractory coating material, a sanding device adapted to deposit sand to the coated set-up and a set-up taking-out device for taking the set-up out of the system. These devices are disposed on a common circle. The system further has aset-up transportation device located at the center of the circle. The transportation device has a plurality of beams extended radially outwardly to positions of the devices on the circle and supported by a shaft which is rotatable and movable up and down. Each beam has an arm which is adapted to hold the set-up. The beams of the transportation device are cyclically moved up and down and rotated back and forth to transport the set-ups from one to the next devices disposed on the circle.

Abstract: An apparatus for cutting off cast parts from a cylindrical runner of a casting body comprises a slidable mount supported on a bed, holding means provided on the slidable mount for supporting and indexing the casting body and a cutting grinder supported up and down movably on the bed. During a forward movement of the slidable mount in the axial direction of the casting body, cast parts arranged in an axial row are cut off successively. After this cutting, the casting body is indexed to the next cutting position and by a rearward movement of the slidable mount cast parts arranged in the next axial row are cut off. Thus cast parts on the outer periphery of the cylindrical runner of the casting body which usually is manufactured by precision casting may be cut off from the runner in the most simple and efficient way.
