SECTIONAL STEAM-GENERATOR,
SPECIPICATION forming part of Letters Patent No. 376,098, dated January 10, 1888. Applicatir n filed April ll, 1887. Serial No. 234,416. (No model.)
To all whom it may concern,-
Be it known that I, JOHN KLING, Jr., a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements iii-Sectional Steam- Boilers, of which the following is a specification.
My invention has relation to sectional steam boilers; and it has for its object a construction of the sections which admits of easily and economically connecting any number of sections together, of correspondingly removing any imperfect or worn-o'utsection from a group of sections for replacement, of presenting alarge extent of heating-surface for each section, and of providing a tortuous path through a group of sectionsfor the products of combustion and heat-currents, whereby part of each section is directly and the remaining part indirectly exposed to the heat of the fire-box to fully utilize the caloric of the same to the-greatest possible advantage before escaping into the stack or chimney.
My invention accordingly consists of the combination, construction, and arrangement ofparts, as hereinafter more fully described and claimed, having'reference particularly to a steam-generator section of preferably a rectangular configuration, having outer long and inner short legs, with open space between the long legs and below the short legs for flrebox or furnace, and above the short legs and between them and the top of the section another open space or flue,"which acts in conjunction with suitable vertical and horizontal flanges projecting from the front and rear sides of the section (when a number of sections are grouped together to form a generator) to direct the heat-currents and products of combustion first against the sides of the sections forming the fire-box, and then from the fire-box to said flue or opening in the sections above the fire-box to the top of the sections, and thence over the top and down the outside of the sections to the stack or chimney, suitable boltconnections being used to secure or group the sections together, and a suitable casing and'cleaning or blow-out pipes being provided for the sections.
Reference being had to the accompanying drawings, which illustratea sectional steam- "generator constructed in accordance with my generator-sections; Fig. 5, an elevation of a generatorsection detached; and Fig. 6, a like view showing its surfaces fluted,-corrugated, or otherwise formed to afford increased heating-surface therefor.
A represents a generator composed of sections (1 a, which are preferably of a rectangular form, as shown, arranged vertically side by side, with intervening spaces and connected by bolts B. Each section has two outer lower legs, a, which form part of the section, and between these are one or more separate shorter legs, a Both of these legs bound a space, a in each section for making a longitudinal firebox or furnace, 0, when a number of sections are grouped together, as shown in Fig. 1, into which the short legs a depend. Above the latter and between them and the top of each generator section is preferably an oblong opening, D, having at its bottom and on each side of the section edge flanges or projecting ledges d. A like flange, d, is provided at the top edges of each section on each side thereof, and like flanges, d and d, are respectively located or formed at the vertical edges of the openingsDand at the outer edges of the legs a, on both sides thereof, which vertical flanges extend or pass up to the top flanges, d. The edges of these flanges come together or meet when the sections are grouped together to provide intervening spaces 6 and 6 between adjoining sections, the spaces 6 communicating directly with the fire-box G and extending up the legs a to the top of the sections, and the spaces e being cut off from such direct communication by reason of the flanges dand d of each section joining each other, as indicated more plainly in Fig. 5.
The various bolt-openings 1, 2, 3, 4, 5, 6, and 7 in the sections are made considerably larger than the diameter of the bolt B, pass- TOO ing therethrough, and these openings on one side of the section having a female joint or socket, I), and on the other side a male joint or coupling part, b, so that when two sections are properly placed side by side the male parts of one fit into the female parts of the other, to make joints between the sections, which joints are made water-tight by suitably inserting asbestos or other desired gaskets, 1), between said parts, as desired or as shown in Fig. 1.
The end sections are provided with suitable eaps,f, for closing said openings, and in these caps the bolts have their bearings, as indicated, so that the sections of a group com munieate with one another by way of openings 1, 2, 3, 4, 5, 6, and 7 at the top, bottom, and intervening parts, and also at their short legs, a. The end caps for the latter may be furnished with suitable blow-out or cleansing pipeconneetions, g g, suitably valved, as deemed necessary, and, if desired, the remaining caps, or such as are essential, may also be furnished with blow-out pipes.
The sections a may be plain, as shown in full lines, Fig. 5, or their surfaces adjacent to the fire-box and heat-fines may be provided with projecting lugs, pins, or ribs for increasing the extent of their heating-surfaces, as indicated by dotted lines w; or the section sides or surfaces may be fluted, corrugated, or similarly configured for a like purpose. The sections are preferably arranged or located within a casing or brick-work, H, having lower back flue, h, which leads to section-openings D, and front upper fiue, h, communicating with openings D and the top and side fines, 7L2 it, respectively, of easing H. From the bottom, preferably, of the fines h a short flue, h, leads toa stack or chimney, h This described construction of sections and easing provides a tortuous passage-way or circulation for the products of combustion and heat-currents through said parts. Thus the flames in the firebox come into direct contact with the long and short legs of the sections and pass directly into the spaces 0 between the sections to the top of the same, being confined thereto by the flanges d and d The products of combustion and heat-currents circulate, as indicated by the arrows in Fig. 1, from fire-box C to due h, into and through section-openings D and into the spaces e between the sections, being confined thereto by the flanges d (t on the sections. From openings D the circulation is thence into flue h, to the top flue, h and side fines, h of the casing, to the chimney orstack fiue h, so that all the surfaces of the sections are successively exposed to the heat-currents, and part of said surfaces are directly exposed to the flamesin the fire-box, to accomplish the best possible results in an economical manner as regards the amount of consumptionof fuel.
In grouping the sections a the edges of their flanges d d d d are preferably covered or smeared with red lead, fire clay, or other material to make tight joints between them.
It is obvious that the details ofmyimprovements may be varied without departing from the spirit of the same.
\Vhat I claim is 1. A steam-generator section having outer lower legs, a, shorter intermediate legs, a", bounding part of a direct flue or-fire'boxspace. a, and a return-fine, D, separate from and cut ofi from fine a" by edge flanges, d d", substantially as set forth.
2. The combination of aseries of steam-generator sections having lower direct flue, a", and upper return-flue, D, cut off from flue a, bolt-openings,end caps, f, and bolts B, passing through the sections and said caps, substantially as set forth.
3. The section at, having opening D, flanges ddd d, and depending short legs or limbs a, provided with bolt-openings which have male and female couplings, respectively, on opposite sides of the sections, substantially as set forth.
4. In combination with a casing or brickwork having top, side, front, and rear interior fines, a sectional generator having through it a fine near its top part communicating with the front and rear casing-fines, and a fire box in the generator-sections communicating with the rear casing-fine, substantially as set forth.
5. The sectional generator A, in which the sections a have fine-openings D and fire box spaces a, in combination with casing H, having front, rear, and top fines communicating with a stack or chimney, substantially as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
