SPECIFICATION forming part of Letters Patent No. 529,805, dated November 27, 1894.
Application filed April 3, 1890. Serial No. 846,485. (No model.)
To all whom it may concern:
Be it known that I, AUGUST POGGENDORF, of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Steam- Boilers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the drawings accompanying this application.
My improvement relates to sectional boilers, and the invention consists in the combination and arrangement of parts hereinafter fully described and embraced in the claim.
In the drawings, Figure 1 is alongitudinal, vertical section in lineawcof Fig. 3. Fig. 2 is a longitudinal vertical section of one of the water sections, showing the alternating zigzag plates therein. Fig. 3 is an end elevation with the outer plating removed. Fig. 4 is a perspective View of the ends of two of the water sections, showing, more particularly,
the holes and nipples by which the parts are connected, and the flanges for locking the parts together. Fig. 5 is an enlarged vertical section through the meeting parts of two of the sections, and showing the nipples fitted in the holes and the flanges resting one on top of the other.
The boiler consists of a series of hollow wa-,
ter sections A A A A set upright on their edges side by side and. closely inclosed in brick-work B. Each of these sections has on opposite sides a series of projections a a in the form of flat faces extending horizontally and longitudinally, which, when the sections are set up, meet at their inner edges.
1) b areaseries of oval shaped flue openings in the sides of each of the water sections for the passage of the heat. Any desired number of these fiues may be used, the drawings showing but three between each two of the sections. The direction of the passage of the heat is indicated by the arrows in Fig. 1, that through the lower flues passing back from the fire box 0 to the rear end, thence up into the middle fiues,thence to the front again, thence up into the upper fines, thence to the rear again and finally escaping into the smoke stack D. The steam that is generated in the sections rises to the top and escapes into a steam dome E, from which it is drawn through pipe 0, to drive an engine or for other purposes. If desired the Water sections may be provided at the ends with water heads A A Each of the alternate water sections A A is provided with conical openings 61 cl in its faces a a, and. each of the intermediate sections A A is provided with conical nipples f f. When the sections are set up the nipples are fitted closely into the holes, thus making water communications between all the sections. Packings of asbestos or other fire proof material 9 g are placed around the nipples, resting between the plates. Each of the water sections also has projecting flanges or ribs h h, which fit together one upon another, as shown in Figs. 4 and 5, thus giving mutual support and binding the sections together so. that they will keep in proper position' and not open the joints at the nipples. These flanges also make a close joint to prevent the heat from passing from one flue to another without passing around the end. The sections may be held together by bolts extending crosswise through the nipples as indicatedby' the dotted lines in Fig. 5, or by any other suitable means. The water is supplied kto the sections through a suitable feed 1 e V r p In this invention there is a very large fire surface acting on thin bodies of water which are rapidly converted into steam. The flues are formed by the section's themselves without the use of tubes. The great number of nipples insures rapid circulation of water, and the interlocking flanges or ribs bind the parts together and make a close joint for the fines.
m m (Fig. 2) are a series of plates inside the hollow sections arranged crosswise of the same and alternating in position as shown. These plates give a zigzag motion to the water as it circulates through the sections.
The'boiler may be made horizontal or vertical. The flues may be round, square or of other shape.
Having described my invention I do not claim broadly a sectional boiler.
What I claim as new, and desire to secure In witness whereof Ihave hereunto signed by Letters Patent, ismy name in the presence of two subscribing IO The combination, with the abutting water Witnesses. sections, of the longitudinal flanges h h resting AUGUST POGGENDORF 5 one upon another, and the nipples ff of one section entering holes d d of the next, as Witnesses: shown and described and for the purpose R. F. OSGOOD, specified. P. A. OOSTICH.
