It will be obeerved that upon closing the bridge Z5 by plaeing a conductor between the two teriiiiiials ihereo'il a current will be sent irom the souroe oi power through ihe conductor 23, a. portion ol' the conductor 24, the bridge 2.5, the red light 27, the conductor 28, and the wire back to the Source ol' power. ,if the bridge 25 is open and the bridge 2G closed by' a. conductor, the current will be transmitted through another part oi the wire 24 -V to the bridge 26, to the conductor 30, and

Yfrom that through the w hite lights 31 through the conductors 2Q and 32 back to the source oi power. Iii order to provide for eoiiveniently operating `theee bridges and eloeiiig and opening theii'i at the proper times, i have located theiii :it the iront and rear sid of the easing, as indicated iu the drawings, and i have provided the rover 15 with a pair oi :iiietal plates $53 and 5, adapted to eli-rae. the bridges 'when the Cover is in the 'proper positioii. .'lheSey plaies are sp ei'inetriieted' that w hen 'the cover is ifioeed the plaie iii closes the bridge 2o :iiid throws on ihe white lights and so that when the @over is thrown bi .'libto the position Shown iii.
