INCINERATOR.

Application filed November 20,1925. Serial No. 70,381.

This invention relates to a refuse incinerator and has for its object the production ofianlapparatus for this purpose which en ables householc refuse and the li.ke to be destroyed quickly, economically and without creating any odors which are perceptible either outside of'the incinerator or on the exterior of the building in which the apparatus is installer.

In the accompanying drawings: Figure 1 is a vertical'section ofian incinerator embodying my improvements.

Figure 2 is a horizontal section taken on the correspondingly numbered line in Fig. 1. Figure 3 isa fragmentary vertical section taken on line 38 Fig. 1.

In the following description like reference characters indicate similar parts on the several figures of the drawings. r v

The enclosing casing of this incinerator comprises a bottom 10-, an uprigl'it body or wall 11 preferably of cylindrical form rising from the bottom and a top 12 forming. a

closure for the upper end'of the wall. The smoke is carried away from this casing to a chimney or elsewhere by a smoke pipe 13 which communicates with the central part of the space withinvtheuppier part ofthe casing and preferably extends'upwardly from Within this casingis arranged a refuse receptacle 1%, preferably of cylindricalform, which terminates at itslower" end above the bottom of the casing so asto forinian ash oi't l5'therebetween and'terminates at' its'u 1 i r J. perend-below the LOP of'the casing sofas to form .a combustion chamber 16 therebetween, and alsoseparated at its sideby an annularspace- 17 from the adjacent part of the body ofthe casingwhichr-forms a vertical passage extending from: the 'ashpit to theicomhnr'e tion' chamber.

This receptacle is providedwith' a plu rality of. perforations 9 which are distributed over this receptacle; and cover the required area of the same-from the supper edge there-' ofltowardlitsilower.edge;

Atits T lower end tlie'P-refuse" receptacle is provided with" a vgrate whichxispreferably constructed in the formofftwo sectronslS 18 arranged paralleland each having a hollow shaft or pipei19 whichisjournaled in:- suitable bearings :and: provided with out; letiopenin'gsKQO whereby thisishaft serves-"as burner-1 byrcsans. of: which ztheega z intros duced to thehollowshaft burns in flamesat these outlet openings and heats the garbage and other refuse which is arranged abovethe burners in the receptacle.

In the upper part of the front side of the casing and receptacle a feed chute 21 extends through the same through which the refuse to be destroyed is introduced into the receptacle and which is normally closed by a door 22.

Air is conducted from the exterior of the incinerator to the space in the upper central part'of the receptacle and easing above; the normal height ofthe pile of refuse in the receptacle by'an air supply pipe having an upper upright section 23 arranged centrally in'the receptacle and having'an outlet at its upper end which terminates above the normal level. of the pile of refuse in the receptacle and preferably below the upper endof thesameand above the top ofthe feed chute 21 I and'also having a'lower horizontal section 2% which extends laterally from the gas delivery pipe '25" forming part of an I auxiliary burner. which. gas pipe terminates atits end within the air pipe section 23 and adjacent to the upper end' of the same and has its lower end passing through and' preferably secured to the lower part of this air pipe. Gasis supplied to 'this'delivery pipe by a horizontal supplypipe 26 eXtendi1'ig, later-ally from the lower endof the delivery pipe through the adjacent part-of the 'recepe tacl'e and casing and provided on the exterior of'the latter with a gas and air mixer 27 by means o-fwhich mixed gas and'air isad mittedto the supply pipe 26 whichburns'in a flame at the upper end of thedelivery pipe 25. 1 I r W'ithin lthe space inthe'upper part of the casing and betweeathe upper end of'the Y form, as shown'by dotted linesin'Figg2 and which projects laterallybeyond these pipes in all; directions so that the lameissuing from them-p per end of I the pipe 23 will be ion deflected laterally therefrom in all directions.

This baf le may be supported in any suitable manner for example by means of hangers 29 secured to the lower end-of the smoke pipe, as shown in Fig. 1. Within the smoke pipe and preferably adjacent to' its lower inlet end is arranged a spreader 30 having preferably the form of a downwardly tapering cone so as to form an annular passage betweeen the periphery of the upper large part of this spreader and the adjacent part of the bore of the smoke pipe. This spreader may be held in place by means of one or more brackets or arms 31 secured to the smoke pipes as shown in Fig. 1.

In the operation of this incinerator the flames from the burner pipes 19 strike the underside of the garbage resting on thegrate within the receptacle and cause the same to be heated which operates to dry the same and generate vapors which are driven off from the refuse. At the same time the air heated by the flames of the grate burners passes from the ashpit upwardly through the annular passage 17 between the receptacle and the casing to the combustion chamber at the upper end of the casing and receptacle while some of this heated air also passes from the passage 17 inwardly through the openings 9 to the side of the refuse in the receptacle and also into the space within this receptacle above the refuse therein, While drying of the refuse is promoted and any volatile gases contained therein are liberated and caused'to separate and rise from the refuse, particularly in the case of kitchen garbage.

While flames are thus issuing from the grate burners, a flame burns at'the upper end of'the auxiliary burner pipe 25 which flame heats the air supplied by the auxiliary air supply conduit 23, 241. This central flame and heated auxiliary air upon issuing from the upper end of the delivery pipe 23 is deflected laterally in all directions by the bafile 28 so as to form a radiating stream of flame and heated air which spreads like a blanket over the top of the refuse in the receptacle. As. a result the combustible gases rising from the refuse due to heating and drying of the same causes the gases to become mixed with the heated air issuing from the central pipe, the openings in the receptacle and the upper end of the side passagel'? and produce a mixture which is highly combustible and constantly ignited by the flame of the central burner pipe 25.

The heatresulting from this combustion in the combustion chamber above the pile of refuse in the receptacle aids materially in. promoting drying of the refuse, such as wet or moist garbage, whereby the mass of refuse isgradually consumed, or destroyed from the top of the pile downwardly to the grate,

and when this is completed the ashes or residue may be dumped from the grate into the ashpit and then removed from the latter through an ashpit door 32 which has the usual air inlet openings 34.

By thus applying a flame and auxiliary heated air to the top of the refuse in addition to applying heat to the bottom and sides of same practically every trace of odor bearing gas is burned immediately upon leaving the mass of refuse, thereby preventing the escape of any unconsumed odor bearing gases to the exterior of the apparatus or the building containing the same, and rendering the use of such incinerators wholly unobjectionable in residental sections of a community.

The flames resulting from the vburningof such gases continue their function upon leaving the combustion chamber and passing around the edge of the deflector or battle and over the latter and upwardly through the smoke pipe.

As the flames, gases and heated air pass upwardly through the smoke pipe the same are again spread by the spreader therein instead of being permitted to pass in the form of a core or solid stream through the" central part of the smoke pipe, therebv further promoting intimate mixture of the heated air with the combustible elements in the gases derived from the garbage or other refuse, and enabling the same to be ignited by the flames and consumed so that no odors are perceptible on the exterior of the apparatus.

Moreover this apparatus permitsof utilizing the heat units in the refuse to the maximum extent for destroying the same or rendering it innocuous, thereby effecting a considerable saving in cost-of gaseous fuel for doing this work.
