IMPROVEMENT IN STEAM-BOILERS.
Specification forming part of Letters Patent No. 20,319, dated May 2-5, 1858.
To all whom it may concern:
Be it'known that I, GEORGE W. BARNETT, of Springfield, in the' county of Clark and State of Ohio, have invented a certain new and useful Improvement in Boilers for Portable and other Enginesfof which the following is a full, clear, and exact description, reference being] had to the accompanying drawings, making part of this specification, in which Figure 1 represents a front wiew .of the boiler; Fig. 2, a view, in perspective, of the furnace removed from the interior of the boiler for the purpose of showing the arrange ment of the smoke-pipes, (to; Figs. 3 and 4, plans of the top and bottom. Fig. 5'represents a vertical section of the boiler and furnace, taken centrally through Fig. 1.
'My invention relates to that class of boilers intended for the rapid generation of steam, more especially to those in which the furnace is so arranged in relation to the boiler that only a small portion of the Water-that is to say, that which is contained at the topshall be exposed to the direct action of the fire, so that steam may be rapidly generated from it without being under the necessity of waiting to boil the whole; and its nature consists in leading the smoke, gascs, and heated air from the furnace, together with the exliaustrsteam, through a pipe or series of pipes so arranged in the boiler that they shall pass downward together through the latter and out at its bottom into the chimney, bymeans of which their otherwise waste heat will be utilized for heating the water, as the steam will dissolve and carry off the soot and other impurities which would otherwise be deposited in the pipesa point of the greatest practical importance, as by the deposition of soot in the pipes the draft of the chimney would not only be greatly diminished, if not entirely stopped, but a very thin layer of it would be sufficient in a great measure of its non-conducting properties to prevent the heat, because of the smoke, &c., from being imparted to the water, and which is the main cause why this class of boilers has not come into more general and successful use.
In the accompanying drawings, the boiler is represented as being of the stationary kindthat is to say,.mounted or supported upon the usual furnace structurebut as no difference in the construction or principle of the boiler is-necessary to adapt it to a portable engine it was deemed immaterial in which .way it was represented. f
The boiler or water-jacket A is represented as being of a cylindrical form, havinga dome or steam-chest, B, arranged on its top, from which the steam-pipeO leads that conducts the steam to the engine, the supply-water being led into the boiler at or near its bottom by means of a supply-pipe, D, or it may be led in at any other suitable point; but the former mode is preferable, as it is always better to be led in at such a point as not to be brought in its cold-condition .in contact with the highly-heated surface of the fire-box, which in other boilers is the fruitful source of violent explosions. The lower end of the water-jacket A is provided with a strong platemetal flange, a,by.n1eans of which it is securely bolted to the fire-box or furnace and the furnace-walls, or where it is applied to portable engines, &e.,- to the frame-Work of the engine. In the front part of the boiler is formed a f urnace-door, E, through which fuel is fed to the fire. The fire-box F is also of cylindrical form, with an arched roof or coyer, f, and, like the boiler, is provided with a mouth, E, formed of cast-iron and riveted to the shell of the fire-box. This mouth is so arranged as to come directly opposite the corresponding opening in the boiler, and is provided with flanges, by means of which it is riveted to the water-jacket in such manner as to form a wa ter-tight joint. On the upper end of the shell of the fire-box is formed a flange, b, to the outer rim of which is secured the section of another, F, of larger diameter, to the upper side of which is riveted or otherwise secured the arched cap-piece f in such manner as to form a water-proof joint. Into holes 0, pierced in the flange b'of the shell, are secured the ends of a series of smoke-pipes, G G, in this case having their lower ends terminating in two main pipes, G G coiled around the firebox and having their outlet through the flange d, secured to the lower end of the shell of the fire-box, and which forms the bottom of the boiler, the flange ct on the lower end of the boiler A and it being securely bolted together for this purpose.
In making the furnace the smoke-pipes G may be made to terminate in as many spiraled mains as may be deemed best,'care being always had to give to them as many revolutions as possible, as the more they have the longer will the waste heat of the furnace and smoke be subjected to the action of the water, and consequently'impart more of its caloric to the water. r
The grate-bars forithe support of the fuel, where coal is used, are arranged as near the top of the furnace as possible; but Where wood,
shavings, or other very inflammable material are used then they are slightly lowered, for
which reasons the grate-bars, for the purpose of using both kinds, had better be made adjustable; but in'this instance they are represented in the drawings as stationary, and 50 arranged as to be adapted to the use'of coal for the generation of steam. The watenjacket 'A and the fire-box or furnacebeing thus constructed, and the latter being considerably less in diameter than the former, it is inserted in the boiler, as shown in section in Fig. 5, and
then securely bolted together at the'ir lower ends and around the furnace-door, so as to form a water-tight joint, when they are'ready to be applied to a portable or other engine, as circumstances may require. By this arrangement and construction of the fire-box and wa ter-jacket it will be apparent that but a small portion of the water in the boiler rests upon the top of the furnace, the greater portion being contained between the sides of the water-jacket and shell of the fire-box; hence the water at the top can be readily boiled or steam rapidly generated without the necessity of wating for the boiling of the whole in the boiler. Again, much less fire will be required to heat that at the top than would be required to heat the whole; hence this arrangemen creates a great saving of fuel as well as a rapid generation of steam and, further, by this peculiar construction of the boiler and arrangement of the flues the waste heat of the furnace and smoke can be better appropriated and utilized for heating the water at the lower part of the boiler than by any other known mode; but as there would be a tendency of the smoke'to form a deposition of soot in the flues, thus destroying-the draft of the fur-l nace, the exhaust-steam is admitted to the flues by means of pipes'through holes e, formed for the purpose in the water-jacket, andcommunicating with a chamber, H, formed of castiron and riveted to the shell of the fire-box,
through which the-fines pass, an opening being formed in them at a point within the chamher for the admission of the exhaust-steam. By this plan not only is the soot prevented from being deposited anda draft created, butthe waste heat of the exhauststeam itself in my name,
