ELECTRIC CLOCK CONTROLLER. The pendulum atthe right hand is of the controlUng clock, and the central pendulum that of a controlled clock; thependulum at the left is a side viewof the central one. C, the bob, is ahollow coil of insulated wire, andswings over two magnets. Mi M2,which have their similar poles fac-ing each other. The ends of the wireforming C are carried up the pen-dulum, pass respectively throughSi S2, and terminate in Ti T2. Tiis joined to T, which crowns thependulum of the controlling clock,and T2 is in connection with bothNi N2, the contact springs of thesame. Both Ni N2 have theirrespective batteries, Bi Ba, butwith opposite poles toward J; soc c that if C is magnetized in one direction by one swing of the pendulum, it will be magnetized in theopposite by the other, thus making a synchronal beat by the con-trolled clock. 694.
