Extra long molds are used for casting these of the ordinary molds and also one-half of a mold for aDutchman joint are shown in Fig. 2. The molds as appliedto the rail are seen in Figs. 3 and 4, Fig. 3 being the outer side. FIG. 5.—SAND BLAST CAR so that cracks do not interfere with the work. The molds are,of course, of cast iron. The base of the rail is well cleaned with a sand blast beforecasting. Fig. 5 shows the sand blast car. Fig. 6 shows thecupola car. The cupola is flexibly supported onsprings, so that there will be as little damage tothe lining as possible in going over special piece of sheet steel over the cupola is raisedto protect the trolley wire from the heat of theblast when the cupola is in operation. If buildingthis cupola car again, Mr. Sloan says he wouldmake a double cupola. The iron used in casting joints is 50 per centNo. 1 soft Ensley and 50 per cent soft machineryscrap. This No. 1 soft Ensley has an analysis asfollows: Silicon, to per , .70 to .85 per , less than .05 per , .30 to .45 per cent. All iron is poured very hot. This is very essen-tial.
