STERNWHEEL DIESEL TOWBOAT BENWOOD UNDER CONSTRUCION—AT LEFT—STEEL WORK FOR THE STERN TO HOLD THE WHEEL, ALSO THREE RUDDERS IN PLACE. to free the engineer from the neces- sity of looking after a circulating water system for the auxiliary units. The 24-horsepower engine is also belt connected to a 4% by 5-inch auxiliary compressor as an adjunct to the regu- lar air starting equipment. The elec- trical end of both generating sets were furnished by the General Elec- tric Co. Fuel oil is carried in three hull compartments which are formed by two oil tight bulk heads and two dividing partitions which split the compartment into three sections. The total capacity is 9500 gallons which is sufficient for 30 days normal opera- tion. THE TOWING KNEES Both the sanitary system and the bilge pump are air operated and the bilge pump connections are so ar- ranged that any compartment can be pumped out. Complete motor driven capstan equipment is provided, the two for- ward capstans being driven by 25- horsepower motors and the. two side capstans with 15-horsepower motors. All these motors are of the heavy duty crane type with resistance con- trol and are equipped with solenoid brakes. The type of motor used is very similar to those used on street railway cars. The heating of the vessel is taken care of with a vacuum type2 vapor AT RIGHT—FORWARD END SHOWING DECK HOUSE, PILOT HOUSE AND system using a Winchester capital boiler which was supplied by the United States Radiator Co. Reference was previously made to the fine maneuvering characteristics of the boats and one of the reasons why this is possible is due to the very complete arrangement of the pilot house equipment. The first detail that strikes the observer en- tering the pilot house is the fine black walnut wheel of the two circle type. This wheel is inlaid with maple and is in itself a very fine example of skilled craftsmanship. Directly be- hind the center of the wheel is located the double control Cory engine room telegraph, one side for each engine, ENGINE ROOM OF STERNWHEEL TOWBOAT BENWOOD—TWO 240 HORSEPOWER FAIRBANKS-MORSE DIESEL ENGINES—CLUTCH CONNECTED TO THE STERNWHEEL DRIVES—IN FOREGROUN D TWO RADIATOR COOLED CLIMAX GASOLINE ENGINES DRIV- ING GENERAL ELECTRIC GENERATORS MARINE REVIEW—June, 1927 19
