SMOKLESS BOILER-FURNACE Specication of Letters Patent. Patented June 27, 1911.

Application filed Augustl, 1909. Serial No. 512,2 8.

To all 'whom ttrmay concem.

Be it known that I', JOHN COOK, a citizen of the United States, and resident. of Buf-A falo, in the countyl of Erie and State of New 'furnates; and it has for its object the pro- '2'0 suring complete combustion.

Qarrangement and combination of S6 ing my invention,

' matically duction of a furnace in which substantially complete combustion takes place inthe combustion-chamber, resultant from the introduction of air at the top 0f the fuel which passes down and unites with an upward' current of` air at a common point, at which point. the fuel is in 'an incandescent state. The air becomes thoroughly heated and unites with the volatile elements, thus asnother object of my invention is the production of a furnace in which the fuel is stored in. two fuel-chambers at opposite sides of a combustion-chamber and is autofed to said combustion-chamber, and in which the air is introduced through the open tops of said fuel-.chambers also l through the sides of the same and through 30 the grate srrpporting the' fuel.

,Other objects of myv invention will be apparent from thefollowing description.

My invention consists in the construction, parts to be hereinafter described and particularly pointed out in the subjoined claims.

In the drawings Figure l is a central longitudinal section' of a furnace embodyelevation. y Fig. 2 is a transverse section taken on line 2 2, Fig. 1. Fig. 3 is a trans,- verse4 section takenJon vline 3 3, Fig.- 1. Fig. 4 is a horizontal sect-ion taken on line 4 4, Fig. 1. Fig. 5*.is a side elevation of one of the side Fig. 6 is an end view ofthe same. Fig. 7 is an enlarged vertical section, taken on .line 7 7, Fig. 5, Fig. 8' is a perspective View of the end of one o'f the actuatingbars for operating t-he closures of the sideair-inlets.

Referringnow. to the drawings' in detail, corresponding letters of reference refer to corresponding` parts in the several figures.

. The reference letter, A designates the oiler `which isl of vthe usual or, any suitboiler limprovements in smokeless boiler passages H1 the boiler being shown in' members closing, the outerl sides of the fuel storage-chambers.

. able construction; it being shown as the f return-tube type beneath which the heat passes and returns through the tubes of the boiler, whence it passes through the drum or ichamber B to thel smoke-stack C. Said is provided with brackets D which 1 are supported on or embedded in the brick` work E surrounding lat least part of the boiler.

Underneath the front end of the boiler :the furnace is divided into three Vchambers by downwardly-converging longitudinally- I disposed water-sections F which extend from the front wall f to the bridge-wall f1; the chambers G, G1 lying outside of said g water-sections being the :lire-boxes and serving also 'as fuel-storage chambers7 while the 'interm'ediatevchamber G2 serves as the comi bustion-cha1nber- It is 'tobe noted that the -fuel chambersG, G1 are gradually enlarged `toward their lower ends, while the co1nbustion chamber is gradually enlarged toward its upper end. j v.

A grate H of any suitable type serves as the'bottom of the chambers G, G1, G2 and separates them from the ash-pit beneath; said grate beingv separated from the lower edges of the4 water-sections F by narrow which connect the combustionchamber G2 with the fuel-chambers G,'G1, as clearly shown in Figs. 2 and'3. v v

In lieu of forming the outer sides of the fuel-chambers of brick, as is generally done, I provide,metallic'water-jackets I which are supported on the ,brick-work closing the ;sides of the ash-pit i and secured at their lends to the brick walls at the front and 'at' the .rear portions ofthe sides.

The4 water-sections F and the waterjackets I` are connected at or 'near their tops f with the boiler by pipes F1, I1, respectively, pipes I1 preferably having indirect -connec tion with the boiler through the upper ends 'of pipes F 1into which they are threaded, as 'best shown in Fig. 2. Said water-sections and water-jackets are also connected at or near their bottoms to the bottom of the boiler by pipes F2, I2, respectively, pipes I2 preferably having indirect connection with the boiler through af portion of the pipes F2 into which they are' threaded. In this `manner complete circulation of the water -is obtained. Any other arrangementfor assuring the through the water-sections and waterjackets may be resorted to, but I consider proper circulation of water' enanas burning fuel at this 'pointl being always free from unignited fuel, there is at all times a bed of incandescent fuel at the lower ends 4ofthe water-sections through which all air and unconsumed productsof combustion must pass. The oxygen in the air passes into the incandescent bed and becomes 'intensely heated. It combines with the incandescent bed of fuel, or the coke. as it may be termed,

and also unites with the Volatile elements,

. assuring complete combustion. The hot air passes rearward through the combustion chamber, through the passage K1, into the* smoke-box K, whence it returns through the tubes ofthe boiler and enters the drum or chamber B, thence out the smoke stack C.

The structure herein shown and described is a representative one only and it is apparent to any one skilled in the art to which this invention appertains. that changes may be made therein without departing from my.

grate beneath said boiler, a combustion chamber centrally over said grate and having its side walls separated from said grate by fuel passages, a'fuel chamber at eachside of said combustion 'chamber having its up.-

perend open, said fuel chambers being provided with air passages, and means for'regulating theair passing through said passages.
