Q.—\\hat means is [irovided su thattransformer will be uniformly cooled? .^.—The transformer is enclosed in asheet iron case and the air enters at oneend and passes out at the other. Inorder to prevent the transformer froiuoverheating at the coils inside of theiron, ducts are provided between the coils?SO tliat the air can pass up through these duets and carry away the heat. Theduels are formed by placing strips ofwood between the coils before they areassembled in groups, and thus manypassages are provided for the air and thewhole mass is kept cool. O. —What two types of transformersare used in connection with locomotivesand car equipments? .\.—The auto and the doubles coiltransformer. <J.—Wiiat dilferenee between the twotypes. A.—Ihe auto transformer has all ofthe coils connected together. The 11,0(K)\hs is connected to the high tension
