STEAIl'Z-BQILER FURNACE.

Application filed (ictober 27, 1821. Serial No. 510,716.

The object of the invention is to proviso an ellicient construction of stean'i boiler one furnace having; improved means for insuring; a proper circulation of the products of such conditions as to utilize most effectively and ecoi'iomically th heat produced by the consumption of the fuel, and also to p (wide a constructio which will have increased stability 2111C strength to resist the pressures to which th same is subjected while affording ain l v means for removing accumulations of soo and ashes from the parts thereof so as t maintain the maximum efficiency at 2. times; and with these objects in view the invention consists in the construction and combination of parts of which preferret embodiment is shown in the accompanying drawings, wherein:

Figure l is a longitudinal vertical sectional view of a structure embodying the inveution.

Figure 72 a transverse sectional view on the plane indicated by the line 2 2 of Figure 1 Figure 3 is a similar sectional View on the plane indicated by the line 3% of Figure 1.

Figure at is a front view of r portion of the structure showing; a o tire refractory lining; thereof.

Figure is an inverted plan view of the boiler alone.

Figures 6 and T detailed sectional views on the planes indicated by the lines ($-6 and T-'T of Figure 1.

The boiler consists essentially of an outer shell or wall 10 and an inner shell or wall 11 of which the latter is arched to form a combustion chamber 1:2 spanning and er;- tcnding rearwardly from the lire box 13, the side portions of the inner wall being disposed in downwardly convergent relation with the lower portions of the outer wall or shell to form downwardly contracted longitudinal pockets 1.4; extending longitudinally of the structu e, said walls being riveted or otherwise effectively secured to longitudinal base bars 1.5 resting upon the base plate 17 from which extend downward the angle supports 18 within which and reinforced by which is arranged the masonry 20 forming the Wall of the furnace proper which includes the above inlicated fire box 13 an ash pit 19 a bridge 1. pa t lo d proper loor 22 and boiler are the upper and lower sets of the tubes and suitable tie rods 8 and extend ng between said front and rear plates, communicating with the rear ones .res-ipectiu ;v of said upper and lower series or fire tub-es are the stack 36 provided with a suitable damper 3? a tie sn'xokc "lue which connnunicates with the rear end of the c inbustion chan'iber, suitable openings 39, 4:0 and all being arranged respectively in alignment with the upper and lower sets of fire tubes and the combustion chamber, at the rear ends thereof and being fitted respectively with movable covers l2, and ld. The rear wall is preferably provided with a refractory lining in which the smoke flue 38 is formed, said liningextending upward beyond the plane of the lower series of tire tubes to a head plate 46 which separates the upper end of the smoke flue from the stack.

At their front ends the upper and lower sets or series of fire tubes communicate with a smoke box 47 fitted with a closure 48 which is connnon to both sets of fiues gives access thereto for cleaning purposes in conjunction with the man hole covers at the rear ends of said lines.

The boiler is preferably equipped at its top with a steam gage 49, a water gage 50, suitable outlet pipes 51 and 52 respectively for steam circulation and safety valve attachinent, and also if desired with an outlet The combustion chamber is spanned transversel b3 front, intermediate and rear drums o6 and 5? terminally secured to the walls of the inner'shell 11 and in communication by means of openings 58 in said shell with the pockets 1 so as to provide for a transverse circulation of watr between said pockets and through the combustion chamber, the front and rear drums being disposed in pendent relation with the boiler with their lower ends exposed and constituting downwardly deflecting baflles for the noducts of combustion, while the intermediate drum is pre'le'ably mounted upon and forms an extension or continuation of the bi' wall to cause the products 01' combustion on leaving the fire box to pass over intermediate or bridge wall drum and thence pursue a downw ;d and rearward course to pass under drun'i 5'? before entering the smoke flue 38. These drums obviously constitute effective means for communicating the heat of the combustion chamber to the contents of the boiler so as to etlect an economy in the use of the fuel and extract the maximum of heat units vfrom the products of combustion be-- the rear pendent bustion chamber may consist as shown of a retractory brick structure 61 extending up iward to the bottom plate (52 ot the smoke box a7.

la ing thus described the invention, what I claim is l. A. boiler furnace having a boiler, a lire box, lire tubes passing through said boiler and leading to a discharge flue, the apparatus having an outlet passage leading from the the box for products of combustion a smoke flue loading from said passage to said tubes, bal'l'les in communication with the water space of the boiler, means mountin f the boiler and supporting one of said battles in said passageway, another of said bali'les depending; into said passageway between the smoke tlueiand the last mentioned battle and providing; between the same and said means a restricted outlet for the products of combustion to facilitate precipitation of solid matter therefrom, and a soot pocket pro vidcd in said means located adjacent the lower end of the depending battle.

A boiler having an outer shell, an arched inner shell, said shells being spaced art at v their side walls to constitute tets, the inner shell constituting a coml'iustion chamber, means providing a the box communication with the combustion chan'iber, supporting means for the shell enclosing the tire box having a bridge wall a d a soot pocket in the rear thereof, a ballle member spanning the inner shell and communicating with said pocket and resting on said bridge wall. a battle member depending from the inner shell spanning the latter and communicating with said pocket, the lastmentioned baflle extending relatively close to said means acent therear extremity of the pocket to provide a restricted space to facilitate precipitation of solid matter from products of combustion.

In testimony whereof I al'lix my signatr EDXVARD T. MOORE.
