culating tubes `7, the

of the heads 10 for the entrance of a suitable cleaning tool,

caps or doors'35 of any suitable construction. By this means access may be had to for inspection at any time.

While prefer to use the combined preliminary and main furnace charnbers D `and E, as above described, the successful opera-y tion ci the invention is notn'ecessarily deio 'pendent on such constructiomasthe boiler is well adapted to use withthe ordinary single furnace oiheatiig chamber, as illusll, e en in 'u on the/ ualit or kind of P g p q y tion, as shown in said figure, is otherwise' substanti ally the same as that just described, the several parts being indicated by corresponding letters and nuiherals the first baiiing-header 10 above main furnace chamber E being -continuously flat like the other headers l0 and-.without the depending rear portion i0', the charging openings and doors 16, l?, being provided with the\ ash doors, grate bars, and other construction, as shown. There itis desired to utilize gaseous fuel, the grate bars may be eliminated and a suitable fuel gas `burner 36 located at a suitable distance below the lowermost series of cirvertical space below such series of tubes being very considerably diminished, as clearly shown in Fig. 5. Such construction` avoids the necessity of ash doors 'or ash receiving space, the circulation of the gases. in combustion following the same course as that provided for in the use of solid yfuel. .In the construction above described, the entire interior of the boiler is filled with circulating water. Where it is desired to' utilize the construction for producing steam, l 4employ a steax drum 37 mounted in the upper portion of the 'boiler structure and supported upon` and secured to the end walls andthe inner edges of the side walls; For

such purpose, the upper end portionsothe end walls, land likewise tiene ot the side walls, are deliected inwardly, as indicated at 38, the water cavities a of the side walls being disposed inwardly toward ,the sides of the drum 37, just below its center, and these inner abutting ends of the side wall terminals are connected with. the shell of the drum by Vcirculating nipples the upper' end portions o and B are provided with semi cylindrical supporting depressions adapted to receive the end portions of the drum 37, the water circulation cavities-ja', b,

- beingvplace'd in circulating connection with the end portions of the drum by means of similar j nipples 40 extending-through the druin, Likewise,v the endn'alls A of? shell of the endwalls andthe shellof' the the openings' being closed by el bemg used.- The eostrucf the upper Side por-- 39 at each side, effectingf communication between the water cavities,

of the sidewalls and the interior steam?, I

f other endlwall', an outlet for theproducts of chamber at the lowerl boiler, an intervening packing 41 of asbestos provided. .The cavities a. and ofthe end walls arealso placed in communication with the `cavities C of the side walls b means of connecting nipples 42, provi ing for ample circulation. An outlet conduit 43 is connected with the drum 37 at any suitable point, as upwardly from the top thereof, for the purpose of making steam connection therewith.

` It will be observed from the constructions shown and described that the entire boiler installation is of metal and is self-contained within the surrounding hollow circulating walls, in combination with the circulating tubes, headers, bridge wall, etc.

l avoid thenecessity of any brick work whatever, and the boiler is thus capable of long continued use without deterioration or necessityA of repair. 'lt is capable of demaintainlng a high or any desired degree of temperature in the water, the boiler is easily regulated and ',controlled, and is especially ('dapted to be used infconnection with the installation of hot water heating systems.

lt will be understood that the advantages of the invention may be embodied in boilers of various capacities or sizes or that the invention may be changed in detail features of construction, but that all such 'changes are-robe considered as within the; scope o the following claims. What l claim is:

1. In a boiler of the'class combination of a supporting described, the

base, hollowv cast side and end walls having hollow nipple connections, inclined water circulation tubes connecting thehollow front and bac walls, water. connections :tor the frontend back walls, a plurality of hollow cast'xnetal headers arranged in alinement with the tially as set forth. '2.' In a boiler of the class described, the

said walls at the corners, a water supply connected tothe base of one end wa1l,.a water exhaust connected to the top of the combustion, a furnace most inner portion of the boiler, a plurality of alternately arranged hollow cast metal circulating baffling each end with' the end walls by tubes, and a series of inclinedl water circulation' tubes connecting the front and back walls, substantially as set forth.
