In view of the dependence of the action of all ordinary types. Fig. 197—Side elevation of the motor of electric motors upon magnetic influences, the curious littlemachine here illustrated is truly unique; for though an electricmotor in the purest sense of the term, yet it derives its motionsfrom forces that are wholly non-magnetic. With the aid of theworking drawings and the hints here given, the amateur mayeasily construct for himself an experimental static motor whoseaction will be highly gratifying and instructive. A horizontally oscillating lever, a, of round vulcanite rod,carrying at its extremities two hollow balls, b and b, of soft pine,communicates its motion through a slender vulcanite connecting 234 HANDY MAN S WORKSHOP AND LABORATORY rod, c, to a light flywheel, d, of thin wood. The lever, a, passestightly through a turned wooden hub, e, into whose lower end isinserted a pivot rod, /, of steel wire, slightly under y% inch insize. The lower portion of f, whose end terminates in a sharppoint, turns freely in a vertical socket, g, risin
