elt thesand is deposited in the elevator Ywhere it is taken to the top of thebuilding. Here the sand is automatical-ly cut and tempered and then depositedin a storage bin where it is allowed tostand for at least a day before using.From this bin, the sand is distributed bybelt conveyors to small storage tankslocated over each molding machine. Achute connected with each one of thesetanks allows the sand, to fall into theflask by gravity. The cope flasks are taken off thebottom end of the gravity conveyorTT by an air hoist and trolley run-ning on the track U as needed for thecope machine A. The drag flasks aretaken off the platform at Q by a trol-ley as indicated by the dotted line toB. The results of the installation indicatethat it has been possible to get verymuch greater benefits from the moldingmachines than could ordinarily be ex-pected. It has been necessary to changeover the methods of operation that hadbeen in use. Molding is now started atseven in the morning, pouring beginning

This makes a con-tinuous flow of wheels from the plantthroughout the day. It thus becomes possible to keep thewheels at a uniform temperature asthey go into the soaking pit, which en-sures a more uniform anneal in the soak-ing pits. It is not necessary to have night gangemployed in the foundry, and this is notonly an appreciable saving, but removeswhat is usually a source of trouble. The same production is now obtainedas formerly and in about one half ofthe floor space previously used. Thelabor cost has been very greatly reducedand the quality of the castings muchimproved. As is usual where moldingmachines are used, the castings have agreater uniformity in weight. There has also been many minor sav-ings which in the a
