VESSELS LAUNCHED AT BUFFALO. - The new revenue cutter George S. Boutwell, built for the United States Government by David Bell, Esq., at his yard in this city, was successfully launched yesterday afternoon in the presence of a large number of spectators. This is the third cutter built by Mr. Bell, the others being the Hamilton and Gallatin. The present craft is differently constructed in some respects from the former ones, and possesses some new features.
The length of the Boutwell is 140 feet overall. She is twenty-two feet beam, seven feet six inches depth of hold and of 230 tons burden. She was built according to plans and specifications sent from the department at Washington, and under the supervision of government officers.
The cutter will be propelled by twin-screws, operated by vertical engines of different sizes, each complete with valve-gear and pumps, and connected, independently of one another, to one of the propellers, so that either may be operated in either direction by using steam directly from the boiler, thus enabling the vessel to be turned almost as if on a pivot. The larger engine may also receive steam from the smaller through an intermediate chamber. The two form a compound engine, in which the higher and lower pressure engines are separately applied to give motion to different propellers. The cylinders are respectively twenty-one and thirty one inches in diameter, with twenty-four inch stroke of piston.
The great peculiarity and advantage of this engine is that it can be used either as condensing, non-condensing or compound. The high pressure engine is on the port side, the exhaust steam from which, instead of being wasted, is utilized for the other engine, and thus in reality one side of the craft may be propelled by exhaust steam. This is an original feature, and, if successful, will doubtless be adopted for many other vessels.
She will carry two twenty-pound guns. The cost of the Boutwell is $70,000.
A fine new tug was launched from the yard of Carroll Bros. at the foot of Wilkeson street yesterday afternoon. The name of this handsome craft is Dave and Mose, after the members of the firm Garson & August, of this city. Her dimensions are as follows: Length, 47 feet; breadth 11 1/2 feet; and depth of hold 5 1/2 feet.
The Girl of the Period is the name of another boat built for Captain Madden, and launched last week from the same yard. She cost $5,600 and is of the following dimensions: 50 feet in length, 11 1/2 feet beam and 5 1/2 feet hold.
The propeller Scotia, owned by Chas. Ensign, Esq., has been completed, and was launched yesterday from the yard of the Union Iron Company. - [Commercial Advertiser.
