LOST MOTIONCONNECTION. The pin A moves as shown by thearrow, pushing lever B aheadof it. One end of this leveris pivoted to C and theother end rests against thecam D. While B is movingfrom a to b, C stands time thus lost is madeup during the rest of therevolution. Thus C revolvesaround the center every timeA does. SECTION XVI. HOROLOGICAL, TIMEDEVICES, ETC. 261 Section , TIME DEVICES, 691. ELECTRIC PENDULUM. P P is the pendulum, W a weight,mounted on a lever, W C A. W C A can move about a center, C, and is at present prevented from turn-ing by the catch, S S. When P Pswings to the right, the lowerscrew in P P passes Under E (seeside view Z) and frees W C C A, under the weight of W,propels the pendulum to the lefttill stopped by a banking, B. P Pmoves on and makes contact withD, whereupon a current passes. Mi M2 become magnetized, and attractL L, the vertical arm of which lifts W C A over the catch, S S, P P leaves D the current ceases, and L L is carried back to itsold position by the action of the spring R. 692. ELECTRIC PENDULUM C is a bob inthe form of an electro-magnet vibrating between thepoles of a. permanent magnet. T and N, reversingswitches operated by the motion of the pendulum. S,direct connection to the ground batteries Pi Pa. Thecurrent is reversed as the pendulum bob nears eachpole of the permanent magnet. Magnetic clocks are thus made
