ABSTRACT:
A foundry mold conveyor system for the intermittent movement or indexing of pallets or other mold carriers successively first past a mold receiving station where a foundry sand mold is placed on each empty pallet, then to and through a jacket transfer station where a conventional jacket is placed on each palletized mold, then past a pouring station where each palletized and jacketed mold is poured with molten metal, then back to and through the jacket transfer station where the jacket is lifted from each poured palletized and jacketed mold, then past a mold discharge station where the poured mold is pushed from each pallet, and finally back through the mold receiving station where a fresh sand mold is again placed on each empty pallet. Pallet movements are effected in longitudinal and transverse paths and jacket placing and withdrawal operations are conducted at a single intersection (jacket transfer station) between a longitudinal path and a transverse path by simple up and down vertical motions of a jacket lifter at such intersection. Also, the use of a double length index on one path permits, despite the intersection, an endless system without paths passing over or under one another.
