Manneetly, the burning ofigzfrbage or other" ondary chamber, air is admitted "thereto primary combustion chamber from a source independent of the supply to the secondary burner and independent, also, ofthe gaseous products of combustion. It is preferred to warm the air, andtnnmx it with gaseous products of .ombustion as the latter flow from the hopper, so that the mixed gases and air are admitted to the secondary chamber and to the secondary burner.

Other features and advantages oi the in vention will appear from the following de tail description.

In the accompanying drawings, I have illustrated one practical embodiment of the invention, but the construction shown therein is to be understood as illustrative, only, and not as defining the limits of the invention.

A designates the outwidc casing. B the which serves in a suitable raised position by feet or legs a. The casin is generally rectangular in form, althougi the shape and dimensions may be varied as desired. The front wall of the casing is provided with a charge opening a which is normally oloaedbym, hopper door a hinged at a, whereby vfhe hopper door may be opened for the purpose of introducing the material into the receptecle or hopper Bel Fu fi ment, tl eifrr wall of the casing is provided wi 5 series of air inlet slots f and with other air inlets g, the purpose 0? which will be presentl described. On the inside of the front wall a is provided ide flanges f, said flanges supportin an guid? 1g a slide F having slots 7" a pted in one position of the slide to re 'eter with slots f in the casing, The slide may be shifted b move the slots f out 01? register with the slots f, thusjcutting off the inflow of air be low the burner, but, obviously, this slide may be adjusted to other positions for regu lntmg the volume 015 air admitted ,to the lower part of the incinerator. Withinthe casing and parallel to the rear wall a there of is a vertical partition G, the some bein supported at its lower end in a horizonta flange 5/ fixed within the lower part of the casing. The receptacle or hopper consists of a front wall b, a back: wall b, side walls I), and a crown sheet B, each preferably composed of cast metal. The side walls b are parallel to side walls a of the casing so as to produce intervening ascending air spaces or lines H, and the lower ends of said side walls I) are supported on the flange ?7' fixed within the casing. The side walls 1/ join with vertical partition (i and these side walls are-provided with an inwardly extending flange l)" upon which rests the lower edge of crown sheet ll. The front wall I) of the hopper or receptacle is joined at its top end to a flange (1 of the door opening frame or the front wall a. of the casing, uh shown in Fig. l, but the loner part of this front wall 11 is seated within a flange 1)" provided on the inside of null 11, below the burner D. An important feature of the invention consists of an offset B provided on the front wall 7), said ollsct extending horizontally across the front part of the. apparatus and at the lower part of the heater.

Various fiorms of operating devices may be used, but, as shown, the grate is rovided at one end with s crank-arm k, t e tray is provided 10 with s crank-arm 1:, and to these crankarms are connected links it k',':WhiCl1 links are pivoted at k to a'spindle K. Said spin- *dle extends through, and is slidebly fitted in, on opening provided in the front wall a of easing A so that the spindle is readily accessible from the outside of the apparatus for the purpose of operetin the grate and the tray. W'hen the spinde occupies the position of Fig. 1 the grate lies across the bottom of the hopper or receptacle so as to support the material therein and the tray is in a horizontal position below the grate to receive liquid matter therefrom, but by pulling the spindle outwardly the links are operated to pull on the crenkerms k k, whereby the grate and the tray are rocked on their pivots, the grate turning toward the right and away from the burner so as to dump the ashes into the ashpen L, whereas "ay is turned to the left so as to discharge any solid matter which may have lodged i u said tray.

The si e wells'b of the hopper or receptucle and. rear artition G are extended up 85 wurdly above t e crown sheet B, the space between said walls being closed by a top In which is below the top a of the outer casing. Between; the top m and the crown sheet B is a secondary combustion chamber M into 40 which the gaseous products of combustion I from the primary chamber B are adapted to flow. said gaseous'products of combustion being mixed with air supplied by fines H the bitter discharging the warm air into the top part of the primary chmnbcr so that the guscs or fumes and the air will be mixed and flow into the secondary chamber. The air and gaseous products of combustion are subjected within the secondary chamber to the flame cn'mnuting from a secondary burncr (l. the some being shown as u horizontal tube extending from front to rear through the chamber M. The burner is provided with no) series oi flame openings 0,

in the respective sides thereof, and to this burner there is connected a pipe 0 positioned outside of the apparatus, which pipe is supplied with air and gas or other fuel. The crown shoot ll is shown us having a depression w uml at the respective sides of this depression are apertures '12, said apertures n being below the secondary burner but quite close thereto.

An exit pipe l extends through the top u of the casing and through the top We of the inside casing, the lower end of said pipe being attached to the inside top m, as clearly shown.

\Vithin the secondary chamber is a baflle Q which extends below the exit pipe P and To is quite close to the crown sheet B. As shown, the baille Q extends in two directions beyond the exit pipe, and the secondary burner O is positioned between the crown sheet and the bnfile. The upwardly flowing gaseous products of combustion and the preheated air flow through the apertures n in I the crown sheet and through the flame emanating from the apertures 0 in the respective sides of burner O, the effect of which is to so consume the obiectionable odors present in the gaseous products of combustion. The heat and gaseous products of combustion flow in two directions below the baffle Q and thence the gaseous products of combustion '55. flow above the bailie and make their exit through the pipe P.

In the side walls 6 of the side casing hre slots T which establish communication between the fines H and the flue I at the rear'of the primary chamber B. The air necessary to support combustion at the secondary burner 0 within the secondary chamber M takes, the following course: The air flows throu h I apertures or slots 9 near the bottom of t 1e outside casing A into the lines H at the re spective sides of the primary chumliier. The ascending air flows through the slots r in the side walls 1/ of the primary chamber and thence into the fine I directly at the backof said primary chamber, whenebyihe ascending air is heated by contact with the walls G I of the lines through which it flows. The air flows out of the line I through the slots at the top of primary chamber B so that the air is cominingled with the gaseous products of combustion.

A feature of the incinerator consists in channels or fines S in one Wall of primary chamber B, preferably the rear Wall (2 thereof. Any desired number of these channels may be used, four being shown in Figs. 4 and 6. The channels extend lengthwise of back Wall 5', they are parallel to each other. and spaced at suitable intervals. As shown. the back wall 0 is cast with hollow ribs which extend into the rear flue I, thus leaving the front surface of the back Wall smooth except Where channels S open through said front surf-nee. The channels are quite narrow, and by occupying vertical positions, there is practically no tendency for small particles of garbage, or other rob use, from passing into the channels-so as to obstruct the 5;! me. The channels extend 12 from the top edge of back Wall I), iiimig the inclined lower part 7) thereof. and to the line of contnc't between the grate wing: c and the rear wall.
