STEAM-GENERATOR.
SPECIFICATION forming part of Letters `Parent No. 366,283, dated nay-12, les?.
Application tiled April 25, [887. Serial No. $236,126. (No model.)
T0 aZZ whom it may concern:
Beit known that I, HOLMES N. "WASS, a citizen of the United States, residing at Viuton, in the county of Benton and State of Iowa, have invented certain new and useful Improvements in'Steam-Generators, ot' which the following is a specification.
This invention relates to steam-generators, and more particularly to such as are used for steaming feed and the like; and my object is to produce a steamer that shall be comparatively inexpensive and simple, and at the same time shall have a large and economical steam'gew erating capacity. L
The invention consists in the peculiar construction and arrangement of the parts of the device, as will be hereinafter fully set forth and claimed.
In the accompanying drawings, forming a part of this specitiatin, Figure` 1 represents a side elevation of the invention, and Fig., 2 a vertical section of the same.
Similar letters of reference indicate corresponding parts.
The boiler consists of'an outer shell, A, which is preferably dared at the lower end, so as to increase the heating-surface, at the same time increasing the relative capacity of the boiler. Vithin this shell is placed a central flue, B, which unites with the boiler at the head, and by a greater iiare at the lower end joins the bottom of the boiler. About midway up the parallel portion of the boiler a diaphragm, O, connects the shell with an intermediate shell, which extends to au intersection with the flaring portionof the flue, as shown in Fig. 2. In practice I also run a connecting-pipe, D, across that part of the Iiue, and thus brace the sides of the crownsheet and still furtherutilize the heat of the combustion-ehamber. The two chambers into which the boiler is divided communicate by means of pipes E F. 'Ihcpipe E is provided with a suitable valve, a, by the opening of which water in the upper compartment runs down into the lower one. 'Ihe pipe F is for steam communication, and connects with the upper parts of the respective chambers. It is provided with a check-valve, b, which allows the steam in the upper chamber to escape into ment in the opposite direction. Near the upper end of the boiler is placed a short feedpipe, c, provided with a suitable cock and adapted to connect with4 a funnel, as shown, 55 by means of which the boiler is charged. -A simple hole in the top of the boiler provided with a suit-able screw-plug, d, may answer the same purpose when there is no steam in theV boiler. The upper chamber is provided with 6o a glass e, to determine the height of' the warter within, and the lower chamber with trycocks for the same purpose. Connected with the bottom ot' the respective chambers are cocks g g', by which the water may be let off 65 from one or both. Near the top of` the lower chamber any desired number of nozzles, h, project from the boiler, and are adapted to counect with hose or pipe G and transfer the steam toa distance for the heating of water or 7o the like, as indicated.
For the uses to which the steamer is ordinarily applied it may be made of heavy galvanized iron and joined bysolder. Being comparatively simple in structure, it is easily and 7 5 cheaply manufactured. rlhe furnace I-I, which forms the base for the steamer, consists in a circular fire-pot, preferably larger at the top than at the bottom, and divided into two chambers by the grate i. The bottom should So extend outward below the doors to form a hearth, and the whole is elevated by suitable legs. The lower edge of the ilared bottom ot Vthe boiler tits outside a bead raised on the upper edge ofthe tire-pot or furnace. It will be seen that the construction is such as to admit ofthe water being quite low in the lower chamber without danger of burning, since it must get below the interscctionof the intermediate shell, I, with the crowirsheet B. llo protect 9o from overheating that portion of the tlue B which is normally above the water-line of the upper chamber, I insert in that portion of the flue a smaller pipe, B, flaring it at the bottom, as shown, thus leaving an air-space between the steam in the chamber and-the, heat inside the flue.
The operation of the invention will now be readily understood. rIhe valve a being open, water fed into the upper chamber iiows into ioo the lower one on reaching the level ofthe valve. The requisite amount is ascertained by the tryby opening the cock a, the pressure in the re-V spective chambers being so nearly equal as to admit of the water flowing down with little or no cessation of steam-generation in the lower l chamber. YVhen the water in the upper cham.
ber becomes too low, it is renewed through the feedpipe without greatly reducing the temperature of the water in thelower one. Should the pressure in the upper chamber at any time rise above that of the lower one, the equilibrium is at once restored by the action of the check-valve b.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- Y l. In combination with furnace H, the boiler composed of the outer shell "A, the inner central flue, B, its lower portion flared to meet the lower edge of the outer shell and form a conical crown-sheet B', the intermediate shell, l, and the diaphragm C, all arrangedr substan tially as and for the purpose set forth.
2. In combination with a furnace, substantially asdescribed, the steam-boiler composed of an outer shell, a central iue flared at the lower end to meet the outer shell and form a conical crown ysheet, an intermediate shell connected with thecrownsheet at the bottom, an annular diaphragm connecting the upper end of the intermediate shell with the inside of the outer shell, and a Hue of smaller size in the upper portion of the central flue, forming an air-chamber between them, substantially as and for the purpose specified.
3. In combination with a furnace, substan tial'ly as described, the steam-boiler composed of the outer shell, A, the internal ilue, B, the diaphragm C, and the intermediate shell,I, and having the waterpipe E and the steamp1pe F, all constructed, arranged, and adapted to operate substantially as set forth.
4. The combination, in asteam-boiler, of the outer shell, A, the central flue, B, having the flaring portion B', uniting with the lower edge of thefouter shell and forming a conical crownsheet, the intermediate shell, I, connecting with the conical crown -sheet, the annular diaphragm C, connecting the upper end of the intermediate shell with the inside of the outer one, and the transverse Water-tube D, all constructed substantially as and for the purpose set forth.
5. In a steam-boiler, the combination of the outer shell, A, having the flaring bottom, as specified, the central ilue,B, having the Hari ng portion B', forming a conical crown-sheet, the intermediate shell, I, connecting at the lower end with the crown-sheet and at the upper end with the annular diaphragm C, the said diaphragm connecting' with the inner sides of the outer shell, the steam-outlets h, and the water-outlets g g', substantially as described. In testimony whereof I affix my signature in presence of twov witnesses.
