484 Jupiter's Electric Machinery The Navy department has received the report of Lieut.-Com'dr C. S. Kempff, who brought the new collier Jupiter from the Pacific coast recently through the Panama canal, during which her turbo-electric propulsive machinery, fur- nished by the General Electric Co., was given a thorough test. Lieut.-Com'dr Kempff states that the Jupiter with an inadequate rudder successfully navi- gated the many tight places, as around | the Culebra cut where only 40 feet clearance in all directions is available, in a most. satisfactory manner. While coming up the coast and steaming at the rate of 1414 knots, the Jupiter, upon sighting an object ahead, in five seconds' time had her motors reversed to full speed astern and was changed to full speed ahead in the same period of time. This ease of control in the turbo-elec- tric drive appeals to naval commanders, as it is believed that great efficiency in maneuvering could be gained for bat- tleships equipped with this type of pro- pelling machinery, and the department is consequently considering its installation in one of the new dreadnoughts. Other valuable advantages of the Jupiter's propulsive machinery brought out by her recent trip are that under favorable conditions she made 12 knots with 20,000 tons displacement on sixty tons of coal a day, a saving of 25 per cent over reciprocating engines. The Jupiter is designed for 14 knots, but maintained 15 knots for a period of forty-eight hours. Her machinery has also made such a good record in repair costs in two years of successful opera- tion that it is ¢onsidered by the Depart- ment to have passed the experimental stage. Miscellaneous R. M. Henningsen has been ap- pointed harbor engineer of Oakland, Cat. The Cowles Ship Yard, Buffalo, has been awarded contract for a steel tug for the Tonawanda & Grand Islarid Ferry Co., Tonawanda, N. Y. Judge Putnam of Portland, Me., has appointed Calvin Austin receiver for the Eastern Steamship Corporation on a petition recently filed by the Ber- wind-White Coal Mining Co. of Phila- delphia. The receivership is considered to be part of a plan for reorganizing the Corporation. An inspection of the Newport News Shipbuilding & Dry Dock Co. and of the property of the Chesapeake & Ohio Railway Co.'s property was made re- cently by H. E. Huntington with the board of directors and other officials of the railway. Homer L. Ferguson, vice president and manager of the ship- THE MARINE REVIEW yard, who is thoroughly familiar with every detail of this extensive plant, con- ducted the tour. The Lidgerwood Manufacturing Co., 96 Liberty street, New York, has dur- ing the 40 odd years of its existence built more than 37,000 electric and steam hoists and a comparison of the type built 30 years ago and that of today is interesting from an engineering stand- point. Contracts for the three new _ bat- tleships California, Mississippi and Idaho, have been awarded by the' Navy department as follows: New York Shipbuilding Co., Camden, N. J., $7,250,000; Newport News Ship- building & Dry Dock Co., Newport News, Va, $7,115,000; Brooklyn navy yard, ore The Kinzie Bros. Steamboat Line, Fort Myers, Fla., has given contract to Wil- liam R. Osborn & Sons, 'Croton; N.. Y., for a shallow. draft freight and passen- ger steamer, to. be named Dixie. The new vessel will be 100 feet long, 20 feet December, 1914 beam and 4 feet 2 inches deep. She was designed by Cox & Stevens, naval architects, New York. In view of the probable increase of trade between the United States and Central and South American ports as a result of the European war, the steam- ers Yoro and Ceiba of the Vaccaro Bros. Line, New Orleans, are being lengthened 40 feet each, at the yard of the Newport News Ship Building & Dry Dock Co. The Pore River Shipbuilding Corpo- ration, Quincy, Mass., recently received an order for 20 submarines, amounting to about $10,000,000. The names of the contractors for these vessels have not been announced, but it is understood that the vessels are not to be delivered in a completed state but in finished sec- tions ready for assembling. The en- gines are to be built at the Groton, Conn., plant of the Electric Boat Co., and the type of submarine to be con- structed will probably be that for which this company holds patent rights.
