ARTHUR BOYCE, OF ST. LOUIS, MISSOURI.-

BOILER-FURNACE AND STEAM-GENERATOR.

SPECIFICATION forming part of Letters Patent No. 519,419, dated May 8, 1894.

Application filed July 10,1 893.

To all whom it may concern: y

Beit known that I, ARTHUR Boven, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in a Combined Smokeless Boiler-Furnace and Steam-Generator, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates. to combined smokeless boiler furnacesand -steam generators, and consists in the novel arrangement and com# bination of parts, as will be more fully hereinafter described. v

In the drawings: Figure 1 is a longitudinal Vertical section taken to one side of the boiler. Fig. 2 is a vertical transverse section taken on the line :1o-a: of Fig. '11. Fig. 3 is a front end elevation. 4

My invention has for its object the saving of fuel and also increasing the heating capacity of the boiler, as well as the successful burning of the smoke and gases generated therein, the same being attended with no greater expense of construction than the orvided with flanges or side plates 2 which rest on brick walls 3 for supporting the same.

4 indicates a smoke passage through which all the smoke and products of combustion and gases which are not consumed, in a manner as will be more fully hereinafter described, find exit to the atmosphere.

5 indicates an end brick wall which is located to the rear end of the boiler 1 and a distance therefrom whereby the smoke-passage 6 is formed. Located in this smoke-passage 6 is a brick-damper 7 the same being pivotally mounted as illustrated in the drawings and adapted to be operated by a handle 8. By this damper a direct draft can be formed or a circumlocutory draft, as will be more fully hereinafter described. f

Located below the brick wall 5 is a sootchamber 9 the same being provided with a soot-door 10 as is illustrated in Fig. 1.

l1 indicates an ash-pit which is located be- Serial No. 479,984. (No model.)

low the grate bars 12 which are of the usual construction.

13 indicates a fire box in which the fuel is placed and 14 indicates the door thereof.

15 indicates a bridge wall which is located in the rear of the' ash-pit 1l 'and the re-box 13, the same being provided with an inclined surface 16.

17 indicates a stratum of dirt which is provided on its top surface with a layer of brick 18.

Located below the boiler 1 is a Water receptacle 19 which is curvilinear in cross-section. ceptacle 19 is comparatively thin as relates to its length andwidtlnthe same being preferably greater in length than the boiler 1 and of greater width than the diameter of the boiler. (See Figs. 1 and 2 for illustration.) Said receptacle 19 is constructed of boiler (See Fig. 2 for illustration.) Said remetal, cast iron, or any suitable material, and

one object is to increase the heating surface of the boiler and another is to act as a means for consuming the smoke as will be more fully hereinafter described.

20 indicates water legs, the lower ends of which are in communicationwith the receptacle 19 and the upper ends with the boiler l 'at the side thereof as can be seen in Fig. 2. Said Water 7legs are secured to the boiler 1 and receptacle 19 in any suitable and mechanical manner.

21 indicates one or a series of water legs which are in communication with the receptacle 19 and are secured directly beneath the boiler 1 and are in communication therewith. Said legs have an additional function of conveying mud or sediment which accumulates in the boiler 1 into the the receptacle 19.

The receptacle 19 as vbefore stated, is located beneath the boiler l'leaving a smoke passage 22 between said boiler and recepta- IOO with a course of tire brick 29,. and superposedA:`

upon said plate 28 is a horizontal fire brick wall 30 which extends from said `front plate 28 to the end of the boiler lfThe front platel 28 is provided with a series of openings 31 which are provided with dampers 32; said openings31 act as airpassages for thead-:i

mission of air into the igniting chamber 211.

33 indicates flue doors,which arejo'f the oi dinary construction, through which admission may be effected to the lues of the boiler.

The `operation ofthe furnace isasfollows:

Y The fuel is vplaeedlintlie fire box y13 and when ignited'bythe operator the smoke ,and .products of combustion .pass backward beneath the' receptacle 19throu`gh the throat 26.31111 channel 23 as indicated by arrowsaudiil the damper `'2" is closed the said smoke and .products of combustion is4 diverted 4and passes backward in an opposite direction through the passage or channel 22` located above the receptacleli) and `when the same getsto the igniting chamber2ltlying above the fire box 13 it is presumedthatq the flame passing upwardlythroughthe. openings25 willvconsume or partially consume. `said` smokev and products of combustion. The remaining smoke and products of combustion `will pass through the iiues of the boiler and, out "throug'hklthe smokepassage 4. `Vihen it is desired to create a straight draft fthefoperator `opens the valve or the damper7 and the smokeor products ofcombustionwill pass directly through the passage or channel23 "Yup through ithe smoke passage `6 and `out at the 4smoke l.passage L As before stated the legati/)1l `actas a conductor or conveyerfor the mud and sedi!` ment .which may accumulatein ,the boiler 1. The mud and `sediment which passes into the receptacle 19 `will gravitate towardthe `edges I of the same, fcr the reason thatysaidreceptacle inclines downwardlyfrom the conte;` as illustrated in Fig. 2 and said mud andsediment may be discharged through the discharge pipe 34: provided with a valve 36 `which* is secured to the under side of the receptacle 19 l. and in communicationtherewith asillustrated in ig.`l. l The object of filling in` the dirtl( is to completely till up all the unnecessary space` so thatiall, the heattmay be.y utilized. `By employing the receptacle 19 it can be `readily perceived that the heating surface of the boiler is very much increased.

35 indicates a stone foundation or base of Iwhichthe hereinbeforetdescribed mechanism is preferably constructed and superposed.

From the foregoing description it can be `readily perceived `thatfa furnace of the above `construction consumes or partially consumes the smoke and products of combustion, that the same may .begvery cheaply constructed, a

`large percentage, ot? the heat generated is utilized; and the heating surface of the boiler is materially increased. t t n `Havingfully Q cr'bed myinvention ,what I claim `is-L` h 1. smokeless boiler,furnacecomprising a boi1`er,`a water reeptaclelocated beneath the boilerw andvhaving' communication" therewith and providedwith a passage, a fire-*boxe or chaniberloicated` below thepassage inthe water receptacle, an igniting chamber located above thepassage in thewaterreceptaclaan air passage located belowthe water receptaclel and providing communication for the smoke and products of combustion'from the fire-box to the igniting chamber, adamper located inthe rear of thelire-bort` wherebythe flow of smoke` and products of combustion is deflected n. and directed,` and a mud exhaust pipelocatedintherear of the receptacle, a1'- ranged and combined in the mannerset` forth forthe purposes stated. 2- A smokeless boiler furnace consisting 0f a boiler such` as n 1,l areceptacle suchwas 19 curvilinear in croslssection, water legs such as 20 `and21wfor aor/ding. communication between said boiler and receptacle, a Iirechamber located beneath said" receptaclm'an `igniting chamber` located above the samepa passage formed in said receptacle for aording communicationk between said l igniting chamber and iirechatnber,` a mud exhaust pipe 34 secured to the rear ofsaid receptacle, a damper 7, a front plate 28 provided with a series of air passages 31and dampers 32, substantially as set forth.

iIn testimony whereof `I affix my signature in presenoeof twowitnesses.
