used to form the U shaped conductor. The size of the perforations and the core bridge there-between must be so proportioned to each other as .to secure:sufficient-strengthand also give sufficient body of .iron'to form the equired'magnet. By this construction the-enrg ng of .an y one of the conductors produces almagnet within the armature, the poles of which magnet correspond with the terminals of .theconductor.

g In practice the movable pole pieces can-be adjusted-so .as to stand at equaldistances fromz-the armature-and thus their effect is neutral. When themachine is in operation,

the electro motive force is built up, at one side of each of the stationary pole pieces respectively. The handle f or levers F F, &c.,'

are then manipulated by the electrician to bring close :to the armature thosemovable pole pieces which "-areupon'the sideoof the stationary pole pieces opposite the built up magnetic force. This operates to bring the built up magnetic force nearer the center of the stationary pole pieces, thusreturning the lines of force to their normal position and form and thus causing the armature to receive the magnetic lines of force more directly than when such lines are deflected from their normal course and from the stationary pole pieces by the built up magnetic force.

Now, havingdescribed my invention, what I claim as new, and desire to secure by Letters Patent, is-- I 1.
