Excerpt: ...6 and 8, through the two circuit-breakers and ammeter to battery; then leaving battery by contact No. 12 of Se, current passes through contacts 15, 16, 14, 7, and 5. At the same time current also passes directly to line from generator by the path 6, 8, 9, 10, 4, and 2, then returns by 1, 3, n, 12, end-cell switches S5 and S6 to 15, 16, 14, 7, and 5. To cut out the battery, and supply the line alone from the generator, S3 is turned to the right and S4 left open. For discharging the battery, S4 is turned to the right and S3 to the left, the former thereby short-circuiting the underload circuit-breaker. The path of the current is then from positive pole of battery through ammeter, this now showing a reversed deflection, --overload circuit-breaker, to 18, 19, 9, 10, 4, and 2, to line, returning by 1, 3, n, 12, to S5 and negative pole of battery. With Sj open, the battery alone supplies the line, but with S2 closed, and the end-cell switches resting on similarly numbered contacts, generator and battery work in parallel. From whichever source the line at any time receives its energy, the current always flows in the same direction, --a condition of importance for the correct registering of meters. The ammeter in this circuit should then have its zero at the left of scale as shown. If the ammeters have external shunts, their location can be a matter of convenience, that for the battery circuit being readily placed between the two circuit-breakers. For the voltmeter, only two connections are needed, --one for generator and one for battery. One other arrangement for a storage battery is known as that in which the regulation is effected by use of qcounter cells.q These may consist merely of unpasted grids, but immersed in acid of the ordinary...This historic book may have numerous typos and missing text.
