The waterwheel governors were guaranteed to prevent a variation in speed ofover 3 per cent with load fluctuations of 25 per cent. A flexible connection between each water wheel and generator isobtained by means of two discs placed close together in parallel These are of the revolving armature type with overhanging collect-or; their output is in two-phase current at a voltage of from 500 to550

A flexible connection between each water wheel and generator isobtained by means of two discs placed close together in parallel These are of the revolving armature type with overhanging collect-or; their output is in two-phase current at a voltage of from 500 to550, and their normal speed is 450 r. p. m. They are erected on con-crete foundations, capped by wooden frames, and in order to insureaccuracy of alignment and to make slight changes more easy, asheet of boiler plate H in. thick was placed on top of each wooden.

This is an improvement over the old frame. This obviates the trouble in the erection of direct-connectedmachines from cutting into the wood while the alignment was beingperfected. The bearings are of the usual self-oiling type with largeoil reservoirs. The armatures are entirely bar wound and the coils ^MdS\culvv^9\gvlc\V* 89 arc held in place with fiber we(l(<es sn that no band wires are re-quired. As a result the armatures remain perfectly reliable undermost trying treatment. The exciters arc of the four-pole type, hav-ing a capacity of ^Y, k. w. each, which is suflicient for two gener-ators, and delivering 125 volts at 1,300 r. p. m. All of the stationwiring is placed in subways made of redwood boards and paintedwi
