The latter is necessary on account of the com-ing of the men to work for the afternoon shift. Thisshuttle connects at the interlocking tower with themain-line service. There is more or less casual travelbetween the shipyard office and the city, which makesit imperative to provide this shuttle service duringthe hours when the demands for traffic do not necessi-tate through service.

There is no lighting fires, getting upsteam or stoking—the engine begins to workimmediately. As to the electric light it is not needful for usto go fully into a matter that could only be ex-plained by a professed electrician, and compre-hended by one familiar with that branch ofscience. Suffice it to say that the principle ofthe light rests upon the sudden combination oftwo opposite electrical currents and the con-version of one sort of force into otherforces—magnetism, or magneto-electricity intoheat and light.

It is not, how-ever, generally advisable to use a battery in this way formaintaining the balance continuously as the cells becomeunevenly discharged. When batteries are used on three-wire systems, they are usually connected across the outsidelines and a switch provided to connect their middle point withthe neutral, so that they can be used for balancing in caseof necessity. 5(y. Fig. 29 shows a three-wire system fed by a 220-voltdynamo A in conjunction with a motor-dynamo a a. Thismotor-dynamo is sometimes called a balancing set or bal-ancer. The armatures a, a are mounted on the same shaftand connected in series, the mid-point n being connected tothe neutral wire.

The upper side ofthe three-wire system requires 6 amperes and the lowerside 3, because we have 12 lamps in parallel in the one caseand 6 in the other.

adlining and e, e are glass rods for separating the plates; m, n arethe heavy copper conductors leading from the battery. Thespace occupied by a battery for a given output will dependon the way in which the cells are arranged, i. e., whether inone or two tiers. Generally, however, 1,000 kilowatt-hourscan be stored per 100 square yards of space. The numberof cells required in an installation will depend on the volt-age to be supplied. In large central stations operating onthe three-wire 110-220-volt system, about 80 cells are used oneach side of the circuit, though the exact number of cellsdepends considerably on the range of voltage required tomeet special conditions. 64. Regulation of Batteries.—In order to fully chargethe cells, it is necessary to have a voltage somewhat higherthan that on which the system is ordinarily run. Of course,this might be obtained by running the generators at a highvoltage, but in most cases this is not practicable, because the 74 ELECTRIC LIGHTING. §17

§ 17 ELECTRIC LIGHTING. 75 machines are generally used to supply current for lightingat the same time that they are charging the cells. In order,then, to raise the voltage on the battery, a booster isused when charging is going on. In lighting work, thebooster is not generally used for regulating purposes, butsimply to add enough pressure to the dynamos to enablethem to charge the batteries. In railway work, where theload fluctuates very rapidly, the booster is so constructed asto make the battery discharge when the load is heavy andcharge up when it is light. In lighting plants, the booster isusually shunt-wound or compound-wound and is driven by amotor. Fig. 71 shows one scheme of connections. Only theessential parts are here shown, so as to illustrate the principlesinvolved without confusing the diagram with the variousinstruments and switches.
