The shaft is of 'steel, solid, 8% in. in di- ameter. As was previously described Dec. 17, there are two patent Ballin wa- ter tube, sectional boilers, each with 4000 sq. ft. of heating surface and individual funnels. The boilers are of vertical: tubular construction with no pipes and are. each tested to 500 pounds per sq. in. pressure, being de- signed to operate at 250 pounds. Nat- ural drait is used. There are four PRest' oil burners for each boiler. Steam, which is used to atomize the Fic. 10--Rivettinc Deck PLates on STEAMER H.-B., Kennepy. crude oil, also increases the chimney: draft, The oil tanks are located on each side of the boat between frames No. 38 and 53, or for a distance of 27 ft. fore and aft adjacent to the boilers. The tanks are isolated from the rest of the boat. They have a ca- pacity of 500 barrels, 42 gallons per barrel. The Kennedy's Auxiliary Machinery. Both the main and auxiliary steam piping is direct and simple and has none of the necessary complications often found on small steamers. Aux- iliary to the surface condenser are two independent Blake air pumps and a Morris Machine Co. circulating pump. Admiralty duplex fire and bilge pumps built by the Blake Steam Pump Co., are installed. The auxiliary machinery includes a Williamson steam steering gear, Corey standard engine room telegraph and General Electric €o. dynamo. The dynamo is conveniently located on the starboard side, with the switch- board. placed between it and the en- gine.. The "dynamo is 7-kilowatt, 118- volt, 575 revolutions per minute, direct connected to a simple, vertical steam engine. Simplicity and positive action in the steering gear is obtained by locating the steering engine directly beneath the pilot house, the rods from the wheel leading straight to the steering engine through a _ vertical enclosed well. The steamer has a capacity of 800 passengers and, as is seen from the foregoing description and the illus- trations, is well adapted for the ser- vice for which she designed. The drawings and photographs give but little idea of the beauty of the was Fic. 8--DetTait oF JAcKS AND BLOCKING Unper Hui Wuen LowerING To LAUNCHING WAYS. She is painted white outside with brass trimmings. The funnels are buff. The cabins are simple in design, excellent in finish, with enough of luxury to be pleasing to the eye and body and not so much as to be cloying.
