ment Co., Westinghouse Electric Products Co., Westinghouse Gear & Dynamometer Co., and the Westing- house Lamp Co. He was a member of numerous busi- ness and social organizations, includ- ing the Union League, Lotos and Rail- road clubs of New York, India House, Bankers Club of America, Universities club, London, the Engineers club, Bos- ton, the Circumnavigators club, the Economic clubs of Boston and New York, and the Exchange club, Boston. He was a member of the board of governors and of the executive com- mittee of the Automobile America. The scope of Mr. Tripp’s activities is further revealed by the following organizations of which he was a member; Academy of Political Sci- ence in the City of New York, Ameri- can Academy of Political and Social Science, Philadelphia; American De- fense Society Inc., American Electric Railway association, American Asiatic Use Diesel Drive in Oil the design and building of the twin screw diesel bulk oil carry- ing barge Typo recently completed by the Sun Shipbuilding & Drydock Co. for the Tidewater Oil Co., New York. The lines were improved and worked out and model tested to give mini- mum resistance for maximum capacity. The contract for building the TypoL was made on Sept. 22 last year. She was launched on April 14 and the contract date of delivery was May 7. The accompanying illustrations show the completed barge and one of the main Winton diesel engines which furnish the propulsive power. Machin- ery is located aft. Some of the prin- cipal hull particulars are as follows: Length on a 12-foot water line, 258 feet 8 inches; length between perpen- diculars, 252 feet; length overall, 269 feet 1014 inches; breadth molded, 40 feet and over fenders 41 feet 5 inches. The depth molded to deck at side amidships is 14 feet while the depth from the bottom of the keel plate butt laps to the highest point of the permanent superstructure is approx- imately 24 feet 6 inches. The sheer at the forward perpendicular is 4 feet ; Pine aesien care was taken in and the sheer at the after perpendicu- lar is 2 feet while the lowest point of sheer is at half length between per- pendiculars. Twelve feet is the de- signed draft on even keel in sea water. As an indication that the designers were under no misapprehension as to the real depth available in transiting the barge canal, the designed draft from bottom of keel plate butt laps on even keel and in fresh water, for this service is 9 feet. Certain other design features of the Typot may be of interest. The straight line pitch of beams in 40- foot breadth is 6 inches. Floor rise at half the molded breadth is 6 inches while the bilge radius molded is 2 feet 6 inches. On a 12-foot molded water line, even keel, and in salt water at 35 cubic feet per ton the dis- placement for the TypDoL is 2755 tons. The block coefficient for displacement and length on a 12-foot water line is .7758. The midship section coefficient to 12-foot molded water line is .9744. Consequently the prismatic coefficient, the block coefficient divided by the midship section coefficient is .8153. The vertical center of buoyancy is 6.751 feet above the base line and the Club of. association, Army Ordnance associa- tion, Caruso American Memorial foundation, Chamber of Commerce of the State of New York, Chamber of Commerce of the United States, Coun- cil on Foreign Relations, Japanese so- ciety, Maine Society of New York, National Electric Light association, National Industrial Conference board, National Inland Waterways associa- tion, New England society, New York Board of Trade & Transportation, and Pennsylvania Chamber of Commerce. Barg S Tydol longitudinal center of buoyancy is 1.03 feet aft of the mid length between perpendiculars considering the volume to the 12-foot molded water line. The center of gravity of the 12-foot molded water line is 5.74 feet aft of the mid length between perpendiculars. To give maximum capacity the length of the parallel middle body is 126 feet while the length of entrance is 50.4 feet and the length of run 75.6 feet. The estimated wetted surface to the 12-foot molded water line is 13,600 square feet. The designed speed in deep water in trial condition is 10 knots and the effective horse- power for the designed. trial speed and condition is 360. Deadweight capac- ity of the TyDOL on the 12-foot mold- ed draft even level keel and in salt water is 1885 tons. There are a total of 15 persons in the personnel of this barge as fol- lows: Captain, two mates, one cook or steward, four seamen, one chief engineer, two assistant engineers, three oilers and one pumpman. Power for propulsion is furnished by two diesel, single acting, four cycle, air injection, trunk piston, di- rect reversible, marine type model A LN TWIN SCREW WINTON DIESEL ENGINED BULK OIL BARGE TYDOL BUILT BY THE SUN SHIPBUILDING & D.
