Nothing in this Title shall be so construed as to prevent from being used, on any steamer, any boiler or steam-generator which may not be constructed of riveted iron or steel plates, when the board of supervising inspectors have satisfactory evidence that such boiler or steam-generator is equal in strength, and as safe from explosion, as a boiler of the best quality constructed of riveted iron or steel plates: Provided, however, That Feb. 14, 1903. the Secretary of Commerce and Labor may grant permission to use any boiler or steam-generator not constructed of riveted iron or steel plates upon the certificate of the supervising inspector of steamboats for the district wherein such boiler or generator is to be used, and other satisfactory proof that the use of the same is safe and efficient; said permit to be valid until the next regular meeting of the supervising inspectors who shall act thereon. Sec. 10. R. S., 4430. Feb. 14, 1903. Jan. 22, 1894. R. S.. 4431. Every iron or steel plate used in the construction of steamboat-boilers, and which shall be subject to a tensile strain, shall be inspected in such manner as shall be prescribed by the board of supervising inspectors and approved by the Secretary of Commerce and Labor, so as to enable the inspectors to ascertain its tensile strength, homogeneousness, toughness, and ability to withstand the effect of repeated heating and cooling; and no iron or steel plate shall be used in the construction of such boilers which has not been inspected and approved under those rules. And the Supervising Inspector-General may, under the direction of the Secretary of Commerce and Labor, detail assistant inspectors from any local inspection district where assistant inspectors are employed, to inspect iron or steel boiler plates at the mills where the same are manufactured; and if the plates are found in accordance with the rules of the supervising inspectors, the assistant inspector shall stamp the same with the initials of his name, followed by the letters and words, 'U. S. Assistant Inspector;' and material so stamped shall be accepted by the local inspectors in the districts where such material is to be manufactured into marine boilers as being in full compliance with the requirements of this section regarding the inspection of boiler plates; it being further provided that any person who affixes any false, forged, fraudulent, spurious, or counterfeit of the stamp herein authorized to be put on by an assistant inspector, shall be deemed guilty of a felony, and shall be fined not less than one thousand dollars, nor more than five thousand dollars, and imprisoned not less than two years nor more than five years. Every plate of boiler-iron or steel, made for use in the construction of steamboat-boilers, shall be distinctly and permanently stamped by the manufacturer thereof, and, if practicable, in such places that the marks shall be left visible when such plates are worked into boilers, with the name of the manufacturer, the place where manufactured, and the number of pounds tensile strain it will bear to the sectional square inch; and the inspectors shall keep a rec ord in their office of the stamps upon all boiler-plates and boilers which they inspect. Every person who counterfeits, or causes to be counterfeited, any of the marks or stamps prescribed for boiler iron or steel plates, or who designedly stamps, or causes to be stamped falsely, any such plates; and every person who stamps or marks, or causes to be stamped or marked, any such iron or steel plates with the name or trade-mark of another, with the intent to mislead or deceive, shall be fined two thousand dollars, one-half to the use of the informer, and may, in addition thereto, at the discretion of the court, be imprisoned not exceeding two years. R. S., 4432. The working steam-pressure allowable on boilers con- R. S., 4433. structed of plates inspected as required by this Title [R. S., 4399-4500], when single-riveted, shall not produce a strain to exceed one-sixth of the tensile strength of the iron or steel plates of which such boilers are constructed; but where the longitudinal laps of the cylindrical parts of such boilers are double-riveted, and the rivet-holes for such boilers have been fairly drilled instead of punched, an addition of twenty per centum to the working pressure provided for single-riveting may be allowed: Provided, That all other parts of such boilers shall correspond in strength to the additional allowances so made; and no split-calking shall in any case be permitted. R.S., 4434. Feb. 11, 1885. No externally fired boiler having its shell constructed of iron or steel plates exceeding an average thickness of thirty one-hundredths of an inch shall be employed on any steam vessel navigating the Red River of the North or rivers flowing into the Gulf of Mexico or their tributaries; and no externally fired boiler employed on any such steam vessel shall have less than three inches space between its shell and any of its internal flues, and not less than three inches space between such flues when any such flues are more than five inches in diameter; and every such externally Feb. 28, 1895. fired boiler employed on any such steam vessel shall be provided with a manhole in the lower part of the front head thereof, of such dimensions as may be prescribed by the board of supervising inspectors, in all cases where the distance between its internal flues is less than three inches. Externally fired boilers having shells constructed of iron or steel plates not exceeding an average thickness of fifty onehundredths of an inch may, in the discretion of the Secre- Feb. 14, 1903. tary of Commerce and Labor, be authorized and employed on steam vessels navigating the Atlantic and Pacific oceans, or salt-water bays or sounds, or the Great Lakes, or any of them, and waters flowing to and from the same, or any of them: Provided, That on inspection no plate that is by this act limited to a thickness of thirty one-hundredths of an inch and no plate that is by this Act limited to a thickness of fifty one-hundredths of an inch shall be rejected for use if found to exceed those dimensions, respectively, if the average thickness thereof does not exceed the limits Sec. 10 therein specified, and the amount of steam pressure that will be permitted to be carried in boilors constructed in accordance with the requirements of this act shall be determined from measurements showing the least thickness of the plates. The feed-water shall be delivered into the boilers in such manner as to prevent it from contracting the metal, or otherwise injuring the boilers. And when boilers are so arranged on a vessel that there is employed a water-connecting pipe through which the water may pass from one boiler to another, there shall also be provided a similar steam connection, having an area of opening into each boiler of at least one square inch for every two square feet of effective heating-surface contained in any one of the boilers so connected, half the flue and all other fire-surfaces being computed as effective. Adequate provision shall be made on all steam-vessels to prevent sparks or flames from being driven back from the fire-doors into the vessel. Every boiler shall be provided with a good, well-constructed safety valve or valves, of such number, dimensions, and arrangements as shall be prescribed by the board of supervising inspectors, and shall also be provided with a sufficient number of gauge-cocks and a reliable low-water indicator that will give alarm when the water falls below its prescribed limits; and in addition thereto there shall be inserted, in a suitable manner, in the flues, crown-sheet, or other parts of the boiler most exposed to the heat of the furnace when the water falls below its prescribed limits, a plug of good Banca tin. 130. Loading safety-valve. Every person who intentionally loads or obstructs, or causes to be loaded or obstructed, in any way or manner, the safety-valve of a boiler, or who employs any other means or device whereby the boiler may be subjected to a greater pressure than the amount allowed by the certificate of the inspectors, or who intentionally deranges or hinders the operation of any machinery or device employed to denote the state of the water or steam in any boiler, or to give warning of approaching danger, or who intentionally permits the water to fall below the prescribed low-water line of the boiler, and every person concerned therein, directly or indirectly, shall be guilty of a misdemeanor, and shall be fined two hundred dollars, and may also be imprisoned not exceeding five years. 131. Water-tight bulkheads. Every sea-going steamer, and every steamer navigating the great northern or northwestern lakes, carrying passengers, the building of which shall be completed after the twenty-eighth day of August, eighteen hundred and seventy-one, shall have not less than three water-tight crossbulk-heads, such bulk-heads to reach to the main-deck in single-decked vessels, otherwise to the deck next below the main-deck; to be made of iron plates, sustained upon suitable frame-work; and to be properly secured to the hull of the vessel. The position of such bulk-heads and the strength of material of which the same shall be constructed shall be determined by the general rules of the board of supervising inspectors. Steam-vessels of one hundred tons burden or under, engaged in the coastwise bays and harbors of the United States, may be licensed by the United States local inspectors of steam-vessels to carry passengers or excursions on the ocean or upon the Great Lakes of the North or Northwest, not exceeding fifteen miles from the mouth of such bays or harbors, without being required to have the three. water-tight cross-bulkheads provided by section forty-four hundred and ninety of the Revised Statutes for other passenger steamers: Provided, That in the judgment of the local inspector such steamers shall be safe and suitable for such navigation without danger to human life, and that they shall have one water-tight collision bulkhead not less than five feet abaft the stem of said steamer. 132. Life boats, lines, and preservers. Every steam-vessel navigating rivers only, except ferryboats, freight-boats, canal-boats, and towing-boats, of less than fifty tons, shall have at least one good substantial boat with lines attached, and properly supplied with oars, and kept in good condition at all times, and ready for immediate use; and in addition thereto, every such vessel carrying passengers shall have one or more metallic lifeboats, fireproof, and in all respects good and substantial boats, of such dimensions and arrangements as the board of supervising inspectors by their regulations shall prescribe, which boats shall be carried in the most convenient manner to be brought into immediate use in case of accident. But where the character of the navigation is such that, in the opinion of the supervising inspector, the metallic life-boats can be dispensed with, he may exempt any such vessel from carrying the same; or may require a substitute therefor, at his discretion. July 9, 1886. Sec. 3. R. S., 4481. Every such steam-vessel carrying passengers shall also R.S., 4482. be provided with a good life-preserver, made of suitable material, for every cabin passenger for which she will have accommodation, and also a good life-preserver or float for each deck or other class passenger which the inspector's certificate shall allow her to carry, including the officers and crew; which life-preservers or floats shall be kept in convenient and accessible places on such vessel in readiness for immediate use in case of accident. Mar. 2, 1889. Every steamer navigating the ocean, or any lake, bay, R. S., 4488. or sound of the United States, shall be provided with such numbers of life-boats, floats, rafts, life-preservers, linecarrying projectiles and the means of propelling them, and drags, as will best secure the safety of all persons on board Apr. 11, 1892. R. S., 4489. Feb. 14, 1903. R. S., 4484. R. S., 4485. R. S., 4486. such vessel in case of disaster; and every sea-going vessel carrying passengers, and every such vessel navigating any of the northern or northwestern lakes, shall have the lifeboats required by law, provided with suitable boat-disengaging apparatus, so arranged as to allow such boats to be safely launched while such vessels are under speed or otherwise, and so as to allow such disengaging-apparatus to be operated by one person, disengaging both ends of the boat simultaneously from the tackles by which it may be lowered to the water. And the board of supervising inspectors shall fix and determine, by their rules and regulations, the kind of life-boats, floats, rafts, life-preservers, line-carrying projectiles and the means of propelling them, and drags that shall be used on such vessels, and also the kind and capacity of pumps or other appliances for freeing the steamer from water in case of heavy leakage, the capacity of such pumps or appliances being suited to the navigation in which the steamer is employed. * * * approved March * * are The provisions of an act second, eighteen hundred and eighty-nine, hereby repealed so far as they relate to the carrying of linecarrying projectiles and the means of propelling them on steamers plying exclusively upon any of the lakes, bays, or sounds of the United States. The owner of any such steamer who neglects or refuses to provide such life-boats, floats, rafts, life-preservers, linecarrying projectiles and the means of propelling them, drags, pumps, or appliances, as are, under the provisions of the preceding section, required by the board of supervising inspectors, and approved by the Secretary of Commerce and Labor, shall be fined one thousand dollars. 133. Stairways and deck room. Every such steam-vessel carrying passengers on the main-deck shall be provided with permanent stairways and other sufficient means, convenient to the passengers, for their escape to the upper deck, in case of the vessel sinking or of other accident endangering life; and in the stowage of freight upon such deck, where passengers are carried, gangways or passages, sufficiently large to allow persons to pass freely through them, shall be left open both fore and aft of the vessel, and also to and along the guards on each side. The captain or mate of every such steam-vessel carrying passengers upon the main-deck shall assign to all deckpassengers, when taking passage, the space on deck they may occupy during the voyage, and such space shall not thereafter be occupied by freight, nor overcrowded by other persons, nor shall freight be stowed about the boilers or machinery, in such a manner as to obstruct or prevent the engineer from readily attending to his duties. For every violation of the provisions of the two preceding sections the owners of the vessel shall be punished by a fine of three hundred dollars. |
