Accommodations . - Figure 5 gives the below- 

 deck layout of the "E. W. Scripps." In the fore- 

 peak is the chain locker, with a passage to the 

 forecastle. There are two built-in and five pipe 

 berths in the forecastle. The crew's lavatory, 

 the captain's room with single berth, and a 

 locker containing carbon-diozide tanks for the 

 fire-extinguishing system open into the fore- 

 castle. Abaft, the galley runs across the en- 

 tire width of the vessel. On the foreside of 

 the galley to port stands a Ray diesel oil-burn- 

 ing range and a water heater and, to starboard, 

 a lO-cu.-ft. electric refrigerator. On the star- 

 board side there are a sink with running hot-and- 

 cold fresh water and a hand pump supplying sea 

 water. Tables, shelves, and cupboards occupy the 

 port and after sides. From the galley a passage 

 leads to the saloon. On the starboard side of 

 this passage are two berths, and on the portside 

 is the engine room. 



In the saloon is a mess table measuring 3 ft. 

 4 in. X 6 ft. 6 in. with a settee on the star- 

 board and after sides and folding chairs for the 

 other two sides. Opening off the saloon is a 

 stateroom with two berths, and a passage leading 

 aft. On the portside of this passEige are situ- 

 ated a lavatory, a single-berth stateroom, and 

 finally a stateroom with three berths; on the 

 starboard side are the door to the laboratories 

 and the companionway to the deck. 



Tanks. - A bulkhead separates the after state- 

 room and laboratory from the lazarette in which 

 are two 650-gallon fuel-oil tanks. The rest of 

 the fuel tanks are in the engine room, making a 

 total capacity of 2000 gallons of fuel oil. Lu- 

 bricating oil is carried in a 50-gallon tank in 

 the engine room and in an 80-gallon tank built 

 under a sideboard in the saloon. 



A total of 635 gallons of fresh water is car- 

 ried in five tanks under the saloon, four to 

 starboard and one to port. Distilled water is 

 carried in a 55-gallon tin-lined copper tank in 

 the after laboratory. Two septic tanks are lo- 

 cated abaft the fresh-water tanks, port and star- 

 board. These take the drains from the lavatories 

 and sinks, discharging to the outside through the 

 bilge pump. 



Machinery . - When built, the vessel was 

 equipped with an 80-HP diesel engine, but this was 

 replaced in 1929 by the present engine, a six- 

 cylinder, four-cycle, direct reversing Winton 

 diesel, rated at 175 HP at 450 revolutions, giv- 

 ing a normal cruising speed of eight or nine knots 

 under power. Originally this engine had an air- 

 injection system, which in 1937 was replaced with 

 a Bosch solid-injection system. Circulating 

 water for the engine is supplied by a 1-HP Fair- 

 banks-Morse electrically driven 1-in. centrifugal 

 pump, mounted on the forward end of the main en- 

 gine, with intake direct from the sea. An air 

 compressor, a 3-HP electric Uinton unit, stands 

 on the forward portside of the engine room. Ar- 

 ranged in a tier on the starboard bulkhead of the 



engine room are eight compressed-air tanks, five 

 of which will carry air at a pressure of 650 lbs. 

 and three at 1000 lbs. for starting the main en- 

 gine. The engine exhaust leads under the counter 

 and discharges below the waterline at the stern. 



A 3-in. centrifugal pump powered by a 3-HP 

 Westinghouse motor placed under the starboard 

 side of the galley serves for fire, bilges and 

 drainage. Fresh-water pressure is maintained by 

 another l-l/2-HP electric pump also under the 

 starboard floor of the galley. Fire protection 

 is provided by a ''CO-Two" system, with both manual 

 and thermostat controls for engine room and bilges. 

 There are also a niunber of portable fire extin- 

 guishers of various types in strategic positions. 



Electrical equipment . - Electric current is 

 supplied by an engine-generator unit mounted on 

 Korfund shock-absorbing springs to port of the 

 main engine. The engine is a model GA-2, two- 

 cylinder, four-cycle Superior diesel engine di- 

 rect-connected to a Westinghouse generator and 

 booster generator. This engine is rated at 21 

 HP at 1200 r.p.m. The main generator is a single- 

 bearing type, with compound-series field winding, 

 and is rated at 115 volts and 15 kilowatts at 

 1200 r.p.m. A special-series field winding is 

 provided for cranking the engine from the bat- 

 tery. The function of the booster generator is 

 to provide the extra voltage needed for charging 

 the batteries as a unit without raising the line 

 potential above the usual 115 volts. The booster 

 generator has a differential-series winding limit- 

 ing the battery-charging current to 40 amperes at 

 10-volt boost and giving a maximum boost of 25 

 volts at no charging current. This differential 

 winding carries the booster-armature current only; 

 the main field has a constant potential 115-volt 

 winding. This method of battery charging also 

 tends to maintain a constant line voltage, since 

 the batteries assist through the booster generator 

 in smoothing out voltage changes caused by sudden 

 load changes. The batteries are Exide Ironclad, 

 type MVA 9-plate lead cells; fourteen 8-volt units 

 in series with a capacity of 137 ampere-hours. 



The speed of the winch motors is regulated by 

 controlling the voltage of the main generator 

 through variation of its field voltage. In this 

 manner a maximum of from 175 to 185 volts may be 

 produced. ^Jhile this control is being used, the 

 rest of the ship's load is taken directly from 

 the batteries; consequently the main electrical 

 system always has a constant potential of about 

 115 volts, for which most of the equipment is de- 

 signed. When the extra voltage connection for 

 maximum hoisting speed is not required, the gen- 

 erator will connect to the line automatically 

 whenever its voltage is normal and will discon- 

 nect when the voltage is reduced. Figure 6 is 

 a diagram of the electrical connections. The 

 Westinghouse switchboard is hinged for rear ac- 

 cessibility and has heavy-duty contactors and re- 

 lays for all automatic hoist-motor connecting 

 functions. Feeder and transfer switches are 

 standard navy-type knife switches.
