MARINE REVIEW. Wor. V1. Engine of Steamship Lismore Castle. The engravings of the two handsome new steamers built by Barclay, Curie & Co., Glasgow, for the Castle Mail Packet Com- pany's South African business, have recently appeared in Lon- don Engineering, from which the accompanying illustrations and description of the engines are taken. 'T'he dimensions of the two new steamers are: Over ali q4ro feet, beam 43 feet 3 inches, depth 31 feet; and the gross tonnage of each vessel is 4,050 tons. They are built beyond the rules of Lloyd's Register, the material used for the hull being Siemens-Martins steel. They are constructed upon the cellular double-bottom principle, without any wells leading into the hold, and thus the maximum amount of safety is obtained. 'They are divided into nine water- tight compartments by transverse bulkheads from the top of the double-bottom to the upper decks, and have two complete steel water-tight decks. For the auxiliary machinery, winches, pumps, windlass and steam capstans, there isa large multitubular boiler, with oN | ai | | : | separate air and circu'ating pumps, so that all the auxiliary machinery is independent of the propelling engines and main boilers. Each vessel is fitted with triple-expansion three crank engines of which engravings are given herewith. The diameters of cylinders are 29%, 48 and 78 inches by 54 inches stroke. The working pressure is 160 pounds per square inch. 'The high pressure cylinder is fitted 'with a piston valve taking 'steam at the middle and' exhausts at both ends. The'intermediate' cylin+ der has the usual double-ported 'slide valve and' the low pressure cylinder a double-ported slide valve. Steam 1s supplied to the engine by two steel multitubular 'double-ended - boilers, each 14! feet'o inches by 18 feet 8 inches Jong. There are six Fox's cotrueated furnaces itr each boiler, with: a separate, com: bustion tain be for eachofurnace» There are 12 furnaces in all, each 3 feet' 4 inches mean diameter: The speed: attained os running "the lights' on the Clyde was 14.4 knots, eee horse power being 3{250, 'and the number of revolutions 75-0 hee propeller is of steel with four blades, the diameter: being 13)deet 6 inches andthe pitch 21 feet 6 inches. | CLEVELAND, OHIO, THURSDAY, SEPTEMBER 22, 1892. No; ra A Marine Organization. The National Board of Steam Navigation held its twenty- first annual meeting in New York last week. The report of the legislative committee called attention to the successful ef- forts put forth in a meeting last March, when a protest was made against the passage of the Frye bill. The committee suc- ceeded in getting amended the life line act so that sound and bay steamers were exempted from its provisions. It was suggest- ed that senate bill 4,684,now in the committee on commerce, pro- viding inspection for all sail vessels, would undoubtedly pass during the coming season. The bill to establish a marine board was considered and the presideut stated that it should be resur- rected and pushed through the house of representatives where it stuck last session. The following officers were elected: F. A. Churchman, Philadelphia, president; B.D. Woods, New Or- ii i ry ve il fA leans, first vice-president; James A. Henderson, Pittsburgh, second vice-president; Addison Lysle, Pittsburgh, treasurer; Charles H. Boyer, New York, secretary; T. W. Venneman, Evansville, assistant secretary. A recent interesting extension of the field of the submarine boat has been made in Italy. The ordinary submarine vessel has been intended and designed almost exclusively for use in war and as a weapon of offense; it has been left for the Italians to organize a company for the recovery of submarine goods, and to design a submarine vessel with this object in view.
