APPARATUS FDR REFUSE INGINERATION AND DISPOSAL Application filed February 28, 1928. Serial No. 257,558.

This invention relates to apparatusfor refuse incineration and disposal and particle, larly to apparatus of this type which is intended for indoor use. The main object of C the invention is to provide an improved apparatus for incinerating' refuse which is of licient in operatioin in which the parts are few and simple, and are also adapted to be economically manufactured.

9 In carrying out my invention Iprovide a casing which preferably contains one or more refuse compartments and an upright flue adjacent the compartment or compartments. If two refuse compartments are employed 5 said flue is preferably arranged between the two compartments and adjacent each of them and ordinarily said flue extends across the interior of the incinerator.

My invention is especially adapted to incinerators in which a line of the above type is formed by upright walls preferably apertured and where the flue wall and compartment wall are arranged asa common wall between the flue and compartment and wherein the apertured walls are in the form of grids. One

object of my invention consists in providing means whereby the grid or grids are sup ported by means of or on the end walls of the casing of the incinerator. Another object of my invention is to provide an. inclined wall in each refuse compartment opposite to the wall forming a wall of the fine, and also to provide means whereby said inclined wall or walls are pivoted so that they can be oscillated by means of a lever, levers or other suitable means placed on the outside of the casing so that the ashes from incineration can be dropped into the ash pan. The said inclined walls serve the purposes of floor men1- bers of the respective compartments and are preferably formed with elongated apertures arranged upwardly. A further object is to provide an improved crown sheet at the up M per part of the casing. And still another object is to provide improved means to con trol the admission of refuse into the incinerating compartments.

The means I prefer to employ for accomplishing the above objects, together with other advantageous and novel features of my improved refuse incineration and disposal apparatus, are illustrated in the drawings accompanying and forming part of this specification, and in which,

Figure 1 is a vertical section of one form of my improved incinerator and taken on the line 11 as shown in Fig. 3.

Like characters of reference refer to like parts in all the figures of the drawings.

Referring first to Figs. 1, 2 and 3 of the drawings, the numeral 2 indicates the casing of the form illustrated in said figures and said casing is preferably rectangular in horizontal section and composed of outer walls 3 and inner ells 4. The casing includes two opposite end walls, preferably inner end walls such as 5, which are particularly employed for a purpose about to be described.

The outer part of the casing in this form of-the apparatus has atop portion such as (l which is preferably provided with an opening for passing in refuse and which is indicated by 7. There a lid 8 preferably hinged at 9 to the top portion 6. In this form of the invention the outer portions of the top portion (tare substantially horizontal and preferablythere is a raised rim 10-. around the opening 7.

The inner casing includes the before mentioned walls 4 and 5 and also a crown sheet suchas 11 made preferably in two parts and having-inclined walls 12 at the front and sides. The forward parthas a charging opening 13 on the edges 13 of which the depending portion 14 0f the lid 8 normally rests. The rearward portion contains the FIT a...)

; tally disposed cover poi'tion'such inner portion 16 of the smoke outlet 16. There is a space 6 between the top portion 6 and the fiat part 11' of the crown sheet and said space communicates with the space 4 surrounding the inner walls of the casing. The space 4' has an opening 2 at the base of the casi'ng and'air camflow'through said opening, up the'space' l to the space G and thence into the smoke outlet 16. This draft of air cools the outer walls ofthe casing during operation of the incineratoran'dalso tends to prevent smoke-from escapingunder the edges of the lid 8.

refuse compartments and in the form herein shown, it contains two such compartments as indicated by I 15. In -this for'mi the said compartments are oppositely disposed with an upright flue structure between them. The

said flue-structure preferably consists oftwo J refuse compartmentseachsuch grid forming a wall of the compartment-adjacent to it.

The flue structure is apertured at the bot-V tom part so that' preferably the fiue 18 i'sfe'n-v tirely open as--at:19,-andthere is a horizonas 20, preferably arcuate in" cross'section. The 4 grids 17' each contain top openings 21' extending horizontally at the upper part but below the cover20and across the grid. 'A' horizontal bar 21d bounds the lowerpart I""'said' openings 21,"and*below said bar are preferably arrangeda series of "vertical bars '21 72 wfith vertical 3178113111138 216 b'GWGQU them. 7 The said b ars 21?) are joined to altm'er hori- .zo'ntal bar'25 which eirtends towards the interior of the adjaceilt'refuse compartment 15. In the opposite side of each of said oompartmentslb is a 'wallsuchas 2-2,in'clined botlf to the grid 17 and to the horizontal. In the form herein show-n thewall-"22 is 'in'the form ofa grid or apertured' walland has a substantially horizontal lower. part 26 which formspart of the floo-r' offitsrespectivecompart'm eiit 15.

Preferably I provide projections suchas 23 on said end walls and-for convenience I place one or more of such projections adjacent the upper part of'eachsuch grid, preferably placing two of the'm 'spacedap'art to supportthe -'grid"on each side. Also'I place one such' proj ection such $1823 underthe en'dof suchigrid, on

each end wall, and preferably four 'more' projections 23 spaced apart, two' each-side of the grid end, somewhat above the projection 23. Thus eachxgri'd will be suitably alined and supportedwat each 'end and may be assembledby sliding it down between said pro ections. Figs. 1 and13jthegrids117whave portions 25 whichiprojecti inwardly so as: to formparts of the floors of the compartments-l5. The inclined Jgri'd or grids 22 have'corresponding portions 26'nearly meeting the portions-'25 lea'vinga space 250 between them for the purpose of clearance *aswill' be neededwhen operating said grid or grids 22' inthe 'manuer'nowto'be described.

There is a notched projection 29 on saicl inember 28 which is adapted to be engaged by the latch 30 so that t-he'gri-d 22 can -be-held in its inoranal'position as shown inFig. 1. v V

There is'an elongated gas burner 31' placed below the flue 1 8,"supported 'by-meanso'nthe casing end walls by lugs 31-, arid there isa gassupply:pipe- 32' connected tothe burner together withanair mi-X'era33. pilot light 3% is also connected to theigasvsupplyrpipe adj acent'to the burner 31' for 'use'when' lighting the same.

@ I have also provided. improved vmeans to As shown in the drawings'in' control and regulate the filling of the compartments 15 with refuse by gravity so as to provide an improved method of drying the refuse and so that or other fuel for the incinerator can be economized. The said means are preferably placed below the opening 7 but higher than the compartments 15 in the space 15 which 1 term the combustion chamber, and in the forms illustrated said means or a portion of the same are placed over the flue cover 20. The said means preferably include a device to permit one of the compartments to be filled with refuse separate from the other, after which the controlling device is shifted so that the second compartment is filled with refuse. Preferabl the first compartment is not lighted until the refuse has remained in it a short time so that the draft of air through theflue will dry the refuse somewhat. If the gas is then lighted the refuse will soon catch fire and the can then be turned off in a short time thus resulting in a saving of The means for controllin the filling of the conuiiartments with refuse consist preferably of a plate such as having trunnions. or short shafts 37 by which it is pivoted in the end walls 5 of the casing 2. One of the trunnions 37 extends through to the outsideof the casing wall 3 and is furnished with a lever 38 by means of which the device is operated. llhere is a segment 39 having three notches ll) and there is a slidable member 11 which can be moved into and out of said notches so that the lever 38 and with it the plates 3Gcan be held in any one of three positions as required. Ordinarily one position is provided for filling the right hand compartment, one for filling the left hand compartment and one intermediate position, where both compartments can be filled at the same time. The plate or deflecting member 36 I sometimes term the refuse gate or controller. The said device may also be used in guiding the flow of and combustion products from the title 18. W hen the plate 36 is turned verti- (rally. the gases and combustion products can flow freely at both sides of the plate. If the plate is inclined to either side the rate of combustion and the gas flow is retarded according to the angle of the plate.

In the form of the invention shown in Fi 6, my improved apparatus is illustrated as a built-in type and it is preferably shown below a flue or air-shaft such as 14i in a refuse disposal apparatus, said flue being provided with suitable openings such as 45 at the several floors of an apartment or other building in which it may be placed. The said openings are ordinarily provided with suitable means for closing them when not in use. The incinerator indicated by 1, its casing by 2, its outer walls by 3, its inner walls by 1- and its inner end walls by 5. The two refuse com- 55 partments are denoted by 15, the upright flue between them by18, the flue grids by 17, the inclined floor grids by 22 and the shafts thereofby 24. The gate or refuse controller is indicated by 36 and the operating lever therefor is not shown in this figure but it will be similar to the form for the type shown in Figs. 1, 2 and 5 together with the notched segment and member on the lever to engage with the segment. i

In this form of the apparatus the grids 17 are secured to the end walls 5 of the casing 2 by means of lugs r projections 48 formed on the grids themselves, and there are bolts 19 passing through said projections 48 and screwthreaded into the said end walls 5.

In either form of the invention shown herein, when it is desired to make use of the refuse gate 36 in filling the incinerator with refus the lever 38 is turned as shown in Fig. for instance, so that only the left hand refuse compartment will be filled with refuse. \Vhen this compartment is filled, the

lever 38 is moved on releasing the member 41 and the gate is shifted to the opposite position, and the lever 38 will be on the left hand side with the member 41 engaging the left hand notch of the segment and the refuse will then drop only into the right hand com partment- 15. l/Vhen the refuse in the left hand compartment is dried sufliciently so that it will burn without uneconomical consumption of gas, the burner 31 islighted by first lighting the pilot light 34 and thenturning the cook 35 of the burner 31. The gas is permitted to burn until it is plain that the refuse will continueto. burn without gas and the gas is then shut off. The heat from the compartment now operating will assist in drying the refuse collecting in the other compartment and alternate burnings can be made and the amount of gas greatly reduced. Vl hen very rapid incineration. is desired the gas will be kept burning throughout the operation.
