Incandescent electric lights . rms the armature, and theygenerate the current. Their extremitiescorrespond to discs of copper (at rightangles to them) laid one against the otherat the ends of the cylinder, and insulatedfrom each other.

The center of the cylin-der itself is occupied outside of the ro-tating axle by a cylinder of wood, which,in its turn, is surrounded by a thick tubemade of a series of very thin discs ofiron, separated from each other by tissuepaper. This arrangement facilitates therapid changes of polarity in the tube is terminated at its two ex-tremities by two thick clamping discswhich are made to compress the others 17 laterally, and the copper discs of theworking coil occupy the two compart-. nients at the extremities of the cylinder,as seen in Fig. 5. Under such condi-tions as these the resistance of the gene- 18 rator is small, and permits of great sub-division of the current in multiple arc; Fig. 6. nor is there any insulation to be burned,and it is even possible, in case of thedeterioration of the bars, to renew them
