Heavy Duty Gasoline Engines The United States is Making Striking In- roads Into the Foreign Market by the Exporta- tion of Gasoline Engines for Use in Commercial Boats. 7 The Internal Combustion Engine as Applied to Small Passenger Boats, Cargo Carriers and Fer. ries. Its Advantages Over Steam as a Prime - Mover. THE LIGHTHOUSE TENDER WOODBINE EQUIPPED WITH S a striking index to the re- A markable development of the gasoline engine in the United States, it is noted that the exports of this type of internal combustion engine to South America alone increased from $332,760 in 1911 to $1,642,447 in 1912. Commenthas alsobeenmadeby English houses that orders for machinery of this character are finding their way into American hands: freely and _ that they are making serious inroads into the British market in the Far East. As an instance of this notation is made of two. 100-H. P. Speedway marine engines, built by the Gas Engine & Power Co. and Charles L. Seabury & Co, Consolidated, Morris' Heights, New York, which were installed in two hulls constructed by W. S. Bailey & Co. at Kowloon, Hong Kong, for the Manila government. The voyage of 636 miles from Kowloon to Manila was made without ~ a stop, the boats averaging about 8Y% knots. Extremely satis- factory has been the performance of the Speedway gasoline working boat. Croton, which was built in 1910 by the Gas Engine & Power Co. for the De- patrtment of Water Supply, Gas and Elec- tricity, Bureau of Water Register, New York. The Croton ts 50 ft: over all, 10 ft. 6 in. beam and 3 ft. 6 im draught, with an average CORLISS KEROSENE ENGINE speed of 12 miles an hour. She is employed in inspection service all the year round in the waters of New York harbor, East River to City Island, Hud- son River and to. -Tottenville, S. T. The Croton has the proved reliability of a steam vessel with the added ad- vantage of being ready at a moment's notice without the necessity of keeping up. steam at all hours: The Croton's log book shows that during the past three years she has achieved a_ mile- age of 38,000 miles, equal to a distance of one and one-half times around the world. This mileage was taken from straightaway runs, not including stops for inspection. Frequent stops are try- ing on a motor, but notwithstanding the great mileage recent inspection of the motor shows little wear, and it is in good condition for many more years of hard. service. The Croton is equipped with a four- THE CROTON, A SPEEDWAY GASOLINE WORKING BOAT cylinder engine, 6% in. bore by 8 in, stroke, developing from 50 to 60 H. P, equipped with mechanical force feed oiler, Bosch dual ignition and Bosch low tension magneto. The accompanying photograph shows the general design of the Croton. Un- der the forward deck stowage space is arranged for, steel bulkheads separat- ing it from the pilot house. The en- gine room is located aft of the pilot house and is also separated by a steel bulkhead. The cabin space aft, which is entered from the cockpit aft, is also shut off from the engine room by a solid steel bulkhead. The Woodbine, equipped with Corliss kerosene engine, was designed by the draughting force of the Bureau of Lighthouses and was originally intend- ed to be a steamer. The contract was awarded to the Waters-Colver Co., of Staten Island, N. Y., but before com- pletion the vessel was taken over by the govern- ment. The hull was towed to Bal- timore and is be- ing completed at the local head- quarters of the United States Lighthouse Engi- neers under the direction of the local office. When the Woodbine was taken to Balti- more, it was de- cided to change the motive power from steam to liquid fuel, and the engine select- ed was a 125-H. P., three-cylinder, four-cycle Corliss,
