IN CINERATQR.

Appli-cation filed December 1S, 1926. Serial No. 155,301.

rlhis invention relates to an incincrator "or destroying the garbage, refuse and waste derived from kitchens or households and to dispose of the 'same vwithout perceptible smoke or odor.

In incinerators as heretofore constructed some difficulty has been experienced in completely lighting the gas used for burning the material which is objectionable not only on account .of the waste of fuel Aand the odors resulting therefrom but also the danger of permitting unignited gas to accumulate vin the incinerator where the same is liable toexplode and cause damage to property and persons.

'.lhe object of this invention is to provide means for lighting the burner and distributor of the incinerator from the exterior thereofvso as to ensure ignition of the gas over all parts of the burner and distributor and thus avoid any explosions, odors or waste of fuel.

ln the accompanying drawings:

Figure 1 is a vertical section of an incinerator provided with my improved lighting means and taken on line 1 1, Fig. 3. Figure 2 is a fragmentary horizontal section taken on line 2-2, Fig. 1. Figure 3 is a horizontal section taken on line 3 3, Fig. 1. Figure 4 is a fragmentary vertical section taken on line l1-4,'Fig. 3. Figure 5 is a perspective view of the distributor containing part of my improved lighting means.

Similar characters of reference indicate like parts in the several figures of the drawings. Y

Referring to Figures 1 and 3, the numeral 10 represents the combustion chamber which is formed within an enclosing casing, housing or shell consistingv of an upright wall 11 and atop 12 which is provided with a smoke pipe 13 leading to a chimney or otherv iiue whereby the products of combustion are conducted to the exterior' of` the building in which the incinerator is installed. In the lower part of this casing is an ash pit 14 which receives air through an inlet 15 on its front side. Between this ash pit and the combustion chamber is arranged a grate which supports the waste material to be de- Y stroyed and preferably consists of two sections 16, 16 arranged side by side with a gap between them.

Extending upwardly from the grate but terminating short of the top of the combustion chamber is a receptacle 17 which is adapted to receive the material to be burned. Thisreceptacle is spaced from the wall of the casing by an intervening upright passage 18 extending from the ash pit to the top of the combustion chamber and provided with a plurality of perforations 19. The material to be burned is introduced into the receptacle through a feed opening or inlet 2O in the upper part of the side wall of the casing and is normally closed by a movable door 21.

Arranged centrally within the receptacle and above the gap between the grate sections is a gas distributor whereby gas flames are directed against the waste material for destroying the same. Thisdistributor comprises a hollow hase 22 arranged diametrically across the lower part of the receptacle and having an open underside, a central opening 23 in its top and horizontal rows o'f side openings 24 in its side walls. Above the base is arranged a pedestal which has a flange 25 at its lower end secured to the base and provided with a hollow upright column `26 which is closed at its upper end and opens part of each of these channels communicates with the interior of the column by one or more openings 29 while the upper par-t of the column is preferably cut olf from direct communication with the channels.

Gas is supplied to the distributor by a main gas supply pipe 30 arrangedl below the base of the burner and extending through the wall of the casing to a gas supply manifold 31 and provided with a hand operated regulating valve 32 'on the exterior lof the casing and a main delivery nozzle 33 at its inner end which is arranged within the central part of the base and projects upwardly toward the lower end of the hollow column. The gas issuing from the main delivery noz- ,zle flows partly laterally into the hollow base and the openings in itsside wall where it burns when ignited in flames against the lower part of the material in the receptacle,

while another part of the gas passes from the main nozzle upwardly into the columns and outwardly through the openings 29 into the lower parts of the channels and then burns in flames, when ignited, which pass upwardly through the channels and against the central partor heart of the mass of rubbish, garbage or similar material whichis arranged in the receptacle around the pedestal.

On top of the pedestal is arranged a bafie 34 preferably in the form of an upwardly dished disk which overhangs the pedestal and operates to deflect the burning flame of gas issulng from the upper ends of the channels laterally over the top of the mass of refuse in the receptacle which is to be burned. This baflie is preferably movedtoward and from its operative position over the pedestal ing lfrom the ash pit through the passagev between the receptacles and the casing to the top of the combustion chamber, thereby drylng the material and burning the same to ashes thoroughly and expeditiously and piti a minimum consumption of gaseous ue 'The means herein shownforlighting the gas issuing'fromthe nozzle 33 of the burner embodying my invention and in their pre. 1ferred form these are constructed as folows:

ply pipe extending through the casing below the baseof the distributor and having its 'outer end provided with -a hand operated regulating valve 39 and connected with the gas supply manifold. Adjacent to one side of the main gas delivery nozzle 33 the pilot gas supply pipe is provided with a secondary pllot lighting nozzle 40 and on the outlet side of the hand valve 39 and within a 1 match hole 41 in the casing the'pilot gas pipe is provided with a vbranch pipe 42 terminating inl a primary lighting nozzle 43.- which vpoints inwardly toward secondary lighting nozzle 40. Immediately above and in line with the secondary lighting nozzle is an upright pilot lighting extension passage which in the present case consists of an upperl section 44 formed on the pedestal between two of the channels thereon anda lower sectionl 45 formed by a short piece of pipe screwed into the lower end of the upper section. At its upper .en d the pilot exthe secondary lighting The numeral 38 represents a pilot gas sup-- tension passage is provided with one or more top lighting openings 46 which are arranged adjacent to the upper ends of the upright flame channels in the pedestal. For the purpose of retaining the secondary pilot nozzle in alinement with the upright pilot passage in the pedestal a fork shaped retaining bracket or guide 47 is provided, this bracket being secured to the lower edge of the base -and embraces the secondary' pilot nozzle, as shown in Figs. 1, 2 and 4.

When it is desired to light the burner of the incinerator the hand valve'. 39 of the main pilot supply pipe is first turned on so as to cause gas to escape from the primary andv secondary lighting nozzles adjacent to the base of the distributorf' A lighted match 48 is now inserted through the lighting opening or match hole 41 within reach of the jet of gas issuing from the primary lighting nozzle whereupon this jet is lit and shoots a flame horizontally inward toward the L.jet of gas streaming upwardly out ofthe secondary lighting nozzle, thereby igniting the gas also at the flatter. When the gas is lit at the secondary lighting nozzle a ame 1s projected upwardly through ally through the top lighting openings 46 of the pedestal. ing ofl'v the gas at the primary pilot lighting nozzle the attendant turns on the mam gas valve 32 and when the gas issues from the central delivery nozzle 33- of this pipe it is immediately ignited by the {iame of nozzle and causedl to burn within the basev of the distributor and issue as flame from the base openings 24 against the lower part of the mass of material to be destroyed. Some of thislburmng gas also passes upwardly into the hollow column', thence laterally through the openings 29, thence upwardly throughthe several channels andagainst the material which bridges the outer sides of the channels, and thence laterally underneath the baflie and over the top of the -pile of refuse .1n the receptacle. IfA for any reason any unigmted gas should rise 4in the column or in one or more of its channels', such gas upon reaching the upper ends of the respective channels will be immediately ignited by the flames issuing from the top pilot lighting openings and caused to spreadv over the top of the refuse.

In this manner itis impossible for any the upright lighting passage and issues laterv large body of unignited gas to accumulate 1n burner the pilot gas supply valve-may be turned off and left in this condition until the next lighting operation.

This lighting device is not only very simple in construction but also permits of positively lighting the gas at the various places where the same issues so as to createl no fear of possible explosion, annoyance or damage due to ignition of any accumulated gas.
