noINVENTIONS 0V NIKOLA TKKLA.of tliis core, he makes it of thin strips, plates, or wires .of softiron electrically insulated as far as practicable. Upon this coreare wound, say, four coils, BBS' B', used as primary coils, and 'forwhich long lengths of comparatively fine wire are employed.Over these coils are then wound shorter coils of coarser wire, c cc' c', to constitute the induced or secondary coils. The constructionof this or any equivalent form of converter may be carriedfurther, as above pointed out, by inclosing these coils with ironas, for example, by winding over the coils layers of insulatediron wire.The device isprovided with suitable binding posts, to whichFIGS. 92 and 93.the ends of the coils are led. The diametrically opposite coilsB R and B' B' are connected, respectively, in series, and the fourterminals are connected to the binding posts. The inducedcoils are connected together in any desired manner. For example,as shown in Fig. 94, c c may be connected in multiplearc when a quantity current is desired as for running a groupof incandescent lamps while c' c'may be independently connectedin series in a circuit including arc lamps or the like. Thegenerator in this system will be adapted to the converter in the
