The engines are totally enclosed, ferced lubrication being employed throughout. There is a_ substantial bed plate; cast in two pieces and bolted together, joined with the alter- nator bed plate at the flywheel end of each engine, the whole being se- cured to the raised engine seatings, which form part of the ship's struc- ture on both port and starboard sides of the engine room. The six cylinders © of the engine are divided into two groups of three cylinders each, the vertical shaft, which drives the cam shaft, being placed between the two groups. The crank shaft is made in AED or aD two pieces, the gear wheel, which 'transmits the motion to the vertical shaft, being bolted between the two flanges of the central coupling and these flanges are turned solid with the shafts. The engines, which are coupled to the alternators in the usual manner, are placed on the' forward end of the machinery space on the port and starboard sides. A _ suitable hand lever barring gear working in an internal rack on the flywheel of each engine provides for turning the engine when required into the start- ing position. Starting is effected by means of compressed air, three cyl- inders only being fitted with starting valves. These are arranged on the three cylinders at the flywheel end of the engine, and their operation is rendered easy for the engineers in charge by a system of bell crank levers and coupling rods transmitting the motion from a control pillar placed on the engine room floor in close proximity to the air receivers of the >, = \ RTE a.\ AHSAN HOS ASS uTLe 9 9 9 @ ae Q| Ol ol Flolo jolFlo}olofFio| ojo Har View itn SIDE Or TANK REmovlD Commeerions omirren | | B RQ Oe eS.

A device for stopping the engine and means of controlling the amount of air delivered by the air compressor are also provided on the same control pillar. Near at hand is the electric controller of the trans- mission system, the whole providing a compact and centralized arrange- ment for the operation of the pro- pelling machinery. At the after end of each engine a three-stage air com- pressor is fitted, driven direct from an extension of the engine crank shaft. This extension also provides means for driving the lubricating and circulating water pumps. The two groups of cylinders comprising each engine are carried by the two en- closed-type columns, each cast in one piece and provided with inspection doors of ample size. To these col- umns on the front or cam shaft sides of the engines cast iron brackets are fixed, which support grating platforms running along the whole length of each engine on the front side. These platforms provide easy access to the valve gear and valves. The valves are situated in the cylinder covers, the fuel valve being of the ordinary needle type, opening vertically upwards. The exhaust and air valves open down- wards, and all are operated by cams and levers in the usual way. An im- portant feature of these levers is the provision of a hinged and bolted joint in each, which allows, by the undoing of one bolt, any lever to be folded a s eriow or AB £ rH BAFFLES Omirred.
