_ Light Weight and Compact Banc. a A Worthington pump, designed at the request of the en gin- ” eer in chief of the United States Navy, to be used for feeding boilers on the steam launches of the naval vessels, is shown in the accompanying engraving. These pumps are now used ex- clusively by the navy department, and are also largely used by builders of steam launches and yachts were compactness and light weight are necessary features. ‘T’he weight, 60 pounds, is exceedingly light, when it is considered that the pump is suffi- ciently strong to work against 250 pounds per square inch. The arrangement and design of water valves ate such as to add novel and valuable features to the pump. The water cylin- der linings and pistons are entirely of composition, and when desired, composition piston rods will be furnished without addi- tional, cost. . The valve motion, while retaining all the valuable consists of but six separate pieces: the most important parts be- ing lubricated by the steam and perfectly protected from injury or derangement from outside causes. The dimensions are as fol- lows: Diameter of steam piston, 2 inches; diameter of water piston,1% inch; length of stroke, 234 inches. Capacity, accord- ing to speed, 2 to 6 gallons per minute, equivalent in capacity to any ‘single-cylinder pump having 154 inch water pistons. For short lengths of pipe the connections are: Steam pipe, 34 inch; exhaust, 4% inch; suction, 1 inch; discharge, 34 inch. ‘These ~ diameters must be increased as the length of pipe increases. Space occupied, 19%x6% inches, and 8 inches high. Shipping weight 60 pounds. This pump can also be fitted with hand lever attachments for filling boilers after blowing off, and for washing decks, etc. It can be run in any position, vertical or horizontal. Treasury Decisions. PIPE OR COIL, BOILERS. Among the July decisions of the treasury department is the following circular order from the office of the steamboat inspec- tion service, which was briefly referred to in the REVIEW a short time ago, and. which is now printed in full on account of the interest shown in this class of boilers on the lakes : Ww To Supervising and Local Inspectors of Steam Vessels, Inspection Service, and others: ‘The supervising inspector of the ninth district has reported to this office the rupture of a steam-drum, 20 inches in diameter, attached to a pipe boiler which had been duly approved by the board of supervising inspectors, under the provisions of Sec. 4429 revised abe such rupture having occurred, as reported, because the material of which it was constructed (iron) was not “rolled to form of shell with the grain of material,” as required by Sec. 7, Rule 2. A test of the material since the rupture shows ample tensile strength for the steam pressure allowed, whether with or ple the grain, though there isa difference of about erp Soe between the two; whereas the reduction of area wit ie a gra H shows 24.32 per cent.; while across the grain, to Ps - ens case the material was subjected to the greatest tensile s sale ithe reduction of area was but 5.94 per cent., or about 9 aa . less than permitted by the rules and regulations, sec. 6, Rule 1. MARINE, REVIEW. i In order to prevent such accidents.in the future, itis deemed advisable that hereafter a sample piece for testing in the usual manner shall be required, and tested under the rules and regula- tions, from all steam drums of boilers applying for first inspection, which are over 15 inches diameter of drum. If drumsare made of, lap-welded piping, such sample pieces shall be obtained by cutting a strip from one end of the pipe, 2 inches wide, so that that the test will be crosswise the roll of the material. If drums are made of riveted iron plate, they must be rolled to form, as required by the rule already referred to. The inspectors will obtain the usual manufacturer’s oath before testing samples, to be filed with their records for reterence. Pd Supervising inspectors, in transmitting their approval to the treasury department, of pipe or coil boilers using petroleum ds fuel, with steam-drums over 15 inches in diameter, will send a copy of the tests of the material of which made, for file with such approval. Local inspectors are directed to require on the name-plates of all new coil or pipe.boilers or steam-generators not constructed of riveted iron or steel plates the shop-number of the boiler, in addition to the requirements of Sec. 20 of Rule 2, for the purpose of identification. JAS. A. DUMONT. Supervising Inspector-General. Owners of Ohio and Mississippi river steamers have been trying for some time past to make captains and their clerks and other officers who are said to be fitted, after a few years of experi-. - ence, to take charge of their boats, but the treasury department has again ruled against them in an opinion, under date of July 17, from Attorney General Miller. He confirms the right of the board of supervising inspectors to make rules and regulations concerning the qualifications of persons for admittance as licensed officers of steam vessels. Sec. 14 Rule 5 of the General Rules and Regulations provides that applicants for the certificate of a master, in the district in question, must have been licensed and served one year as first class pilot or chief mate on lake, bay or river steamer. : In the case ofa foreign vessel that had been wrecked in American waters, sunk and abandoned for two years, the depart- ment allowed free entry of wrecked goods. In a letter to the collector of customs, Port Townsend, Wash., in regarding the wrecked goods, Assistant Secretary.O. L. Spaulding says: “It being understood that the vessel has been for two years sunk in the waters of the United States and abandoned by her owners, you are hereby authorized to allow the landing, without entry and free of duty, of any goods which may be recovered at Port Angeles, in your district, which is the nearest port to the wreck.” THE Erie Railway has placed a new and elegant line of sleeping and parlor cars on its trains between Cleveland and Pittsburgh. The night train, 11:00 p. m., will carry straight sleeper of latest design and provided with every comfort and conyenience, while the afternoon train, 2:55 p. m., will have drawing room car, perfect in every appointment. These cars have been especially prepared for the service and are excelled by none. Reserve space at 141 Superior street, Weddell House block. $6.00—Chicago excursion, October 3, via the Nickel Plate.
