:This invention, stated in its broadest terms, relates to heating apparatus and has Vmore especial relation to'a sectional boiler. ,i

One object of, the present Invention is to provide a Vsectional boiler of -simple constructionand of high eciencyl equally welladapti ved for steam, hot water,A or vapor heating vplants at a costnot exceeding conventional Y 4sectional boilers.y

Another `object of the present invention'is to provide a construction in whichdeinite separate channels are provided for the upward and downward circulation of the water inl eachsection.

A Another object-of the present invention is to provide a construction in which each channel for the upward ow of the water is of one size and shape, in `cross-sectional area throughout its length, and it without branch connections or connectionsto other channels Vat any point between the bottom-intake opening and the top exitopening of-each tube.V

Still another object of the presentinvention is to provide a construction in which the cross-sectional area of the sum of the cross-sectional areas ofall upward channels towhich it connects.

which my invention consists can be variousl A arranged and organized and that in int i D vention is not limited'to'tlie precise arranger ment and organizationof the instrumentalities as herein shown and described.

Referring to the drawings in detail, the

reference numeral ltl'designates the frame vof the lire box in which may be placed an oil burner, a gas burner, or a fire may be built ther-ein for the purpose of generating heat.

Mounted upon the tire box frame is the secf tional boiler embodying the invention, and a description will first be given of a coinplete section or. unit which may be made of cast-iron, brass, aluminum, or other suitable lmetal. `A section or unit comprises a rectangular, box-like structure having a substantially L-shaped open portion upon two of its opposed vertical faces. Arranged within this open portion are a plurality of tubes, tlireeiin number, for the circulation fg; ofwater.

These tubes, three in number, which are designated 12, 13, and 14,are formed as an integi'al part of the section or unit- 11. Each of these tubes is of L-shaped Vconliguration with its lowerniost or horizontal portion slightly inclined upwardly in a direction toward the vertical portion of the tube. Between each of these tubes 12, 13, and 14 there is provided a space which -spaces are designated'l, 16, and 17, for the passage of combustion gases between the tubes. The

reference numeral 18 designates "one of the water legs with which the tubes 12, 13, and

i Vthe topfof .the tubes12,.13, Vand 14. The ref- .erence numeral 25 `designates a line-way or 14 communicate. rlhe reference numeral 19 designates an oppositely disposed water leg also with which the tubes 12, 13, and 14 communicate, as they do also with the steam space or dome 30. TWithin this latter water leg 19 is arranged a vertically disposed balile plate 2OA which parallels the vertical inner wall of the leg and is spaced from the inner wall ofthe water leg to forni a narrow channel 21 between the water leg 19 and the outer wallg-of passage'22 which is in communication with the fire box. The lower end ofthe baffle plate is arranged in horizontal alignment withthe nipple openings 23 and 24 at the bottom of the boiler section and thetop of the baliie plate is arranged ina plane at channel which is horizontally arranged to receive the combustion gases from the passages 15, 16, 17, and 22 from which the same pass to a flue box and thence to a chimney, not shown in the drawings. The iiue-way or channel 25 in cross-section is about onehalf the cross-sectional area of the boiler section itself. The reference numeral 26 designates the upper nipple opening of the boiler sectionll and which is of relatively large diameter. This nipple opening 26 is located Vwell above the tops of the water tubes 12,

13, and 14 and to one side thereof in contradistinction to immediately above the same. The normal water level of the boiler sections ;is"atleastthree vinches above the bottom of the nipple opening 26, so that'plenty of steam "space '30 is present above the water tubes to permit of uninterrupted agitation, thereby providing a delinite, continuous circulation of water through the entire boilei-and each section.. As clearly shown in Fig. 3, the

water tubes vhavestaggered relation one with anotherso that a tortuous path is, provided for the travel of combustion vgas-es between :the-.tubes b oth horizontally and vertically consider-ed.` The reference numeral 27 designates the water inlet connection, and 28 designates the outlet connection. `Each of the nipple topenings at one end of the Aboiler sec- .f

tion is closed by means of a plug 29 and a cover `plate 30 may be fitted over theL- shaped space of each end oft-he boiler section, the same having been omitted in Fig.

nl for the purposes of better illustration. if. While Iliaveshown my boiler sections as mounted upon a lire-box, obviously the boiler sectionsmayhave their bottom portions eX- tended to Yform feet if desired.
