SEABURY’S SAFETY WATER-TUBE BOILER. (SEE ILLUSTRATIONS.) _ The builders of the steam generator represented in the illustration have furnished the following descrip- tion: “This water-tube boiler, having so many good qualities and having proved so very satisfactory in every instance where it has been placed in boats, and being designed and constructed after considerable ex- perience with a number of water-tube boilers, is offered to the public with earnest belief that it is the freest steaming and longest lived boiler in use to-day; all the claims made for the boiler ‘have been proved by actual tests. With the de- gree of skilled labor and manufacturing facilities employed in its construction, the very best re- sults are obtained. It has been approved by the Board of Supervising Inspectors, and is built to conform with their rules and regulations. The material throughout is of the best; steel in drum and tube plate is 60,000 T.S. Tubes are of the best charcoal iron or steel. Each and every piece used in this boiler is carcfully inspected and’ tested before being placed in position, and again tested to 600, lbs. hydrostatic pressure after the parts have been assembled. There are a great many seemingly well designed boilers that have _ proved unsatisfactory for the reason that there have been no means of cleaning soot and ashes off the tubes, and it is a well-known fact that boilers deteriate.more from corrosion than from actual wear in use. Of course, there area few = boilers that never reach the corroding point, hav- ing proved useless before they had time to corrode out. The object sought for most in the designing was to havea boiler arranged in such a manner that without much work it could be easily kept clean both internally and externally, and as the weight of boiler is carried from tube plate, inde- pendent of the lower half manifold, itis an easy matter to remove the cap nuts, taking off steel straps and removing half manifolds. This can be done by working from ash pan, as the sides of same are made so they can be removed; also taking off drum head. Itis then possible to pass a wire brush through these tubes from drum, and all dirt will be carried dowa with brush. It is also possible to look through tubes by lowering a small-electric light in the tube to the bend, from upper end, and looking up from lower end, then reversing the operation and looking down from upper _ end, as drum is sufficiently large to admit.a person go- ing inside, thus insuring the inside of tubes being clear of all the scale, grease or dirt. As the tubes are placed in rows at right angles to each other, it allows the use of a scraper or small bellows being used between them to remove any dirt, soot or ashes; the tubes can ‘then be given a coat of zine paint to protect-them from corrosion (this is usually done. at the end of the season). There is more effective heating surface in this boiler than in any other made, where dimen- ~sions. of casing are the «same. The ratio of heat- ing surface to'grate sur- - face is more than the aver- -age boiler, and is what ex- -perience has shown to be right. This boiler is not the lightest one made, but . is as light as is consistent with long life; but where light weight is desired, it can be built to compare : with the lightest. Openings are provided in front of the casing at feed water heater, and the feed water heater is spaced so that steam pipe with perforated end and hose can be used between them their entire length and width, for blowing off soot and ashes, thereby insuring clean heating surface and free draught, which will give Bartlett § Co., N.¥. THE MARINE RECORD. 2) the most economical results. All boilers from four feet wide and upwards have the tubes expanded at both ends, and tube plate is of sufficient thickness to stand the pressure without the need of stay bolts. A’ hand- hole plate is placed at one end for cleaning half mani- folds. The joint at tube plate and half manifolé is that known as the rebate joint, packed with asbestos, and as this joint is so well known, it is: not necessary IN THE ENGINE. ROOM. CUTTING A GASKET... © The inexperienced engineer who tries to cut a gasket by first marking it out with a rule and dividers and then spaces off and lays out the holes is very clearly ‘‘not in it’? with the man who understands his business, says Tradesman. That man will not try any measuring or spacing business, but will place the sheet or rubber on the flange it isto fit and with a small,round faced hammer he will go lightly over each line of surface boundary, both curved and straight. He will tap lightly so as not to strike through the rubber cloth and damage the iron work, yet the blows are heavy enough to cut the fabric nearly, if not quite in two. are several holes or a more or less complicated bolt holes, then put bolts or tightly fitting pieces of wood in the holes cut to hold the gasket in place while he is cutting the balance of the way around. In this manner the gasket is cut out exactly to the Shape of the surface upon which it is to be placed, and that, too, without the trouble of meas. uring, using dividersor maintaining a knife sharpe enough tocut rubber. The only requirement is to strike light with the hammer, so as not to in- jure the corners of the iron. DON’T FOOL WITH MOVING MACHINERY. I have seen more injuries received from attempt- ing to tighten some moving part of an engine than from any other source, and it is strange what men will attempt todo. I had an engineer once whom Iwas compelled to discharge, because he was for- THE SEABURY BOILER. to dwell on its merits here; it is used in boilers from four feet wide to eight and nine feet wide, any length. Above eight and nine feet wide, a drum of a size large enough to allow a workman’ going inside to expand tubes, etc., is used at sides of boiler, instead of half manifold; also a central cluster of tubes are added, making two furnaces instead of one. Below four feet in width the lower manifolds are of a forged steel pipe sufficiently thick to stand the pressure without chang- =I S = (Old i 4 k ra ever adjusting the engine when under motion; he would tighten or loosen eccentric straps, adjust the length of the eccentric rod, the valve stem, or try to tighten the crank pin brasses, with the result that he was forever getting a bang on ‘the head with a wrench that was knocked ott of his hand and the engine was crippled again and again.
