There are two centrifugal pumps,
each worked by a separate engine for circulating water through the
condenser, and these are so arranged that they can be connected to the
bilges in the event of an accident to the ship. In the engine room
there is fitted an auxiliary feed donkey of the duplex type and made
by the Fairfield Company.
This pump has all the usual connections, so that it can be used for
feeding the boilers from the hot well, for filling the fresh water
tanks, for pumping from the bilges, or from the sea as a fire engine.
The engines are arranged in the ship with the starting platform
between them; and the handles for working the throttle valves,
starting valves, reversing gear (Brown's combined steam and
hydraulic), and drain cocks are brought together at one end of the
platform, so that the engineer in charge can readily control both
engines. The two sets of engines are bound together by two beams
bolted to the framing of each engine. This feature was introduced into
the design for steadiness.
The method of supporting the propeller shaft brackets is interesting,
and we reproduce a photograph that indicates the arrangement adopted.
Instead of the A frame forming part of the same forging as the stern
frame, the Fairfield Company have built up the supporting arms of
steel plates riveted together, as is clearly shown.
