TB-21 CTB-8 Bailey

The torpedo-boat destroyer has a double duty, to attack an enemy's ship when opportunity serves, and primarily to assail the torpedo-boats of the foe, trusting for success to her greater weight and speed. For this purpose she is adapted to discharge a projectile in advance, as she chases an adversary through the waves. Of boats of this class in the American navy may be named the Bailey, a craft authorized in 1897, two hundred and five feet long, nineteen feet wide, and of six feet draught. She was of 235 tons displacement, her power being estimated at 5600 horse, and her speed at thirty knots, though a higher speed may be developed.

Her two 18-inch torpedo-tubes were supplemented by four 6- pounder rapid-fire guns. Of these guns, two were mounted on the main deck and two on the forward and aft conning-towers, the latter having nearly an all-round fire.

A distinguishing characteristic of these boats is their immense power as compared with their size. The engines of the Bailey, with her 235 tons displacement, will have more than half the power of some ocean packets of 8000 tons. Speed is the one essential requisite, and everything else is subordinated to this. The crew, about thirty in number, will be obliged to accommodate themselves in a contracted space, the four cylinder triple-expansion engines, four boilers, and two fire-rooms taking up a lion's share of the under-deck room, while a large share of space must be given to the coal, of which sufficient will be provided to enable the Bailey, when not driven at full speed, to steam 3000 knots.

The torpedo-boat destroyer Bailey was launched into the Harlem river from the yard of the Gas Engine & Power Co., and Charles L. Seabury & Co., Consolidated, New York City, on December 5. The boat was christened by Miss Florence Beekman Bailey, grand-daughter of the late Rear-Admiral Theodorus Bailey after whom the boat was named. An artistic silver loving-cup is to be presented by the family of Rear-Admiral Bailey, upon which a suitable inscription referring to the services of the Rear-Admiral under Admiral Farragut will be engraved.

The official trial of the torpedo boat Bailey, built from their own design by the Gas Engine and Power Company and Charles L. Seabury, Morris Heights, New York, took place in Long Island Sound on the 25th of April, the mean speed for the two hours being 30.2 knots. No difficulty whatever was experienced in reaching the contract speed, there being an abundant supply of steam throughout, and the speed at one time reaching 31.12 knots with 418 revolutions of the engines. The Bailey ran her "standardizing" trials several months earlier, but, owing to the intensely cold weather prevailing, her official trial was postponed until danger from ice was over.

The Bailey is one of the three boats authorized by act of Congress of March 3, 1897. She had hitherto been classed as a torpedo-boat destroyer, but was now placed in the list of torpedo-boats of the navy. The other two vessels authorized under this act are the Goldsborough, built at Portland, Ore., and the Stringham, which was launched some time earlier in Wilmington, Del.

The Bailey was of the following dimensions: Length, 205 feet; beam, 19 feet 2 inches; mean draft, 6 feet; displacement, 235 tons. She is fitted with twin screws, driven by triple-expansion engines of the builder's design, which are expected to develop 5600 horse-power. Her estimated trial speed is 30 knots.

As fitted on the torpedo boat Bailey, the Seabury boiler presents an unusual construction. There are four curved downtakes, two at each end. The generating tubes, curved for the greater part of their length, have straight ends, and, therefore, enter the drums at an angle. The two inner rows form a wall which is open at the top, and the two outer ones, a wall open at the bottom, forcing the gases of combustion to take the course shown by the arrows. The small spaces left at the top of the outer wall are closed by asbestos. The drum, inside of the casing, is protected by asbestos, and this covering extends down along the outer wall of tubes for some distance. About three-fourths of the tubes are 1 inch, and the rest, placed at the inner and outer walls, are 1-J inches in outside diameter. The front and back of the single furnace are of brick. The corrugated ash' pan protects the inner tubes below the grate. The grate is 9 feet long, formed of four lengths of bars, and 6J feet wide.

The closed fire room system is used, the air entering the ash pit at the front and back. The uptake is in the middle of the length of the boiler. The feed water is discharged downwards, the end of the feed pipe being well inside of each downtake. The amount of water in this type is larger than in other tubulous boilers. Owing to the position of the water drum and the adjoining casing, these are exposed to the action of the water in the bilge, and therefore, much more liable to corrosion.
