As the force thesechaplets are compelled to resist is thedifference in weight between the coreand the amount of metal it displaces,and as this is distributed among alarge numberi, no great strain is placedon any one chaplet. As radiator molding is carried onwithout the use of bottom boards, andto give the molds the desired incline tofacilitate the running of the metal, twostraight edges are imbedded in eachfloor throughout its entire length. Be-tween these the molder prepares a levelsurface with another straight edge uponwhich he sets his drags, after which thecores are placed, the copes rammed andthe molds are closed. The general view of one section of thefoundry is shown in Fig. 2. This de-partment is 200x110 feet and is divi
