' My invention relates to improvements in boiler constructions,'and"it consists in the combinations, constructions, and" arrangements'herein described and claimed.
An object of my invention is to provlde a boiler construction in'which a novel fin'struc- .ture is employed whereby a maximum heating surface is attained, and inwhich the generalboiler design is suchithat oil or gas burners maybe effectively employed.
A further object is to provide a boiler in which the fin construction is arranged in such a manner that theseelements serve a double function as supporting and reinforcing elements.
A further object is to providea boiler construction designed in such amanner that the] necessity for stay bolts and similar bracing is entirely dispensed with, irrespective of the capacity of the boiler.
larly pointed out in the appended claims.
My invention is illustrated in the accomapplication, in which Figure 1 is a sectional View of a boiler embodying'my invention,
Figure 2 is a sectional view taken along the line 2-2 of Figure 1, and
Figure 3 is a diagrammatic front elevation of the boiler.
and a second chamber 6 which communicates with a flue 7 The burnt products of combustion pass to the chamber 6 and therefrom through the flue 7. The base is provided with a second flange 8 adjacent to which a' cylindrical member 9 is positioned. This member is provided with aplurality of openings 10, see Figure 2, in its wall for receiv-' ing fins 11.. The sides of the fins and their lower ends are preferably positioned within the openings 10 and may be connected with.

may be provided with suitable dampers. Certain of the fins are slightly 'shorterthan the remaining fins for'xpermitting the constructionof the opening 12 in :the' side of the boiler." In the present layout, two of'the fins are shortened. 'In other respects these two fins areidentical' with the remaining fins. TA crown sheet 1i is secured-to the upper ends of the fins. The crownsheet is prefer- T ably provided with openings 'conforming-to-- the shape; of the fins for receiving the ends jofthe latter. The fins may beweldedto the crownfl'sheet; jThe crown'sheet-is provided I i with a flang'e'115 havinga ring 16' which; pro Other objects and advantages will appear in the following specification, and the novel features of the invention will be particu- The cylindrical member Qmay their sides. byfmeans of closure plates-17" These plates may be also; welded to'tlieffins.
The outer diameter of the ring 16-issoinewhat larger than thediayne'ter ofthe'imember The ring is cut out for receiving the upper i ends of apluralityof hollow curved members 18.- These members are secured within openings 19 in a web 20 which forms a part of the base .4; The lower ends' of the members 18 may be welded within the openings 19'. 'It
will-thus be-seeii 'that'the interior of *the member 9,-,whichfmay'be termed' aniinner shell, is placed in communication with the "chamber 6 through the medium'of themem bers 18. The burntproducts of combustion from "the interior of the some may 'pass'} downwardly through the members 18 intothe 1 chamberjfi and through-the flue 7. The boiler'may be provided with a water glass 21, see Figuref3, and a plurality of tri- :cocks722. The boiler in the presentinstance is provided with a waterand steam chamber 23'above the crown sheet 14. Theboiler may be provided with inlet pipes 24,-"outletfpip'es h I bewelded'to' the ring; The portionsof the fins whichare 1 disposed] above the ring 16 are closed upon panying drawings, forming part of this together than the lower ends.

In operation, a burner of any suitable type is placed within the chamber 5. This chamber, together with the interior of the member 9, may be defined as a combustion chamber.
7 The specific construction disclosed in the present instance is primarily designed "for use in connection with oil and 'gas burners, The structure may be narrowed upwardly rather than having 1 the fins arranged in parallelism as shown in Figure 1. In other'words, the upper ends of the fins may bearranged closer Any suitable typeof oil or gasburner may mayalso belined with fire brick, if desired. The base may also be provided with openings forreceiving conduits and the like associated a with the burner structure, I In the present insurfaces provided by these elementsare posii tioned WhBI'fL-Bftllfi heat is most intense; The

Flames ina boiler of this'type tend tomove toward the center-of the device and work upwardly. I The, V arrangement of the fins is such thatthe flame and the burnt products of combustion may move freelyand atthe same time a maximum heating efliciency; is provided. fThe burnt," I
