Application March 26, 1945, Serial No. 584,751

2 Claims.

This invention relates to garbage and trash incinerators, and the primary object of the invention is to provide a simple and eificient device of this kind whose use does not require careful separation of the garbage and trash.

A further object of the invention is to provide an incinerator of the above kind embodying a compartment for reception of tin cans and in which the cans will be subjected to the heat of the burning garbage and other trash so asto be conditioned for ready destruction and disposal.

Another object of the invention is to provide an incinerator of the above kind in which the tin can compartment is arranged to permit ready discharge of the cans from the compartment to outside the incinerator after being subjected to the heat of the burning garbage and other trash.

Still another object of the invention is to provide the incinerator with a fly trap permitting passage of flies into the incinerator when attracted therein by the garbage, but excluding entrance of light from the outside so that escape of the flies from the interior of the incinerator is minimized and destruction of such flies is effected when the garbage is consumed by fire in the incinerator.

A still further object of the invention is to provide an incinerator of the above kind having a series of spaced superposed grates composed of spaced grate bars, the spacing of the bars of the grates diminishing from the uppermost grate to the lowermost grate so that, as the garbage and trash burn, they will gradually fall down from one grate to the other and scatter until completely consumed.

Other objects and features of the invention will become apparent from the following description when considered in connection with the accompanying drawings.

In the drawings, wherein like reference characters indicate corresponding parts throughout the several views:

Figure 1 is a front elevation of an incinerator embodying the present invention.

Figure 2 is a top plan view thereof.

Figure 3 is a horizontal section taken on line 33 of Figure 4.

Figure 4 is a vertical section taken on line 4-4 of Figure 1.

Figure 5 is a fragmentary vertical section taken on line 5-5 of Figure 1.

Figure 6 is a fragmentary vertical section showing a modification in which the fly trap is arranged in the lower portion of the incinerator '55 2 below the grates, instead of above the grates as shown in Figure 4.

Referring in detail to the drawings, 5 indicates a housing provided with a central smoke outlet or pipe 6 at the top and having a series of spaced superposed grates I, la, lb, 7c and 1d mounted therein so as to provide a combustion chamber 8 above the grates and an ash pit 9 below the latter. The housing has a front opening 10 in the lower portion thereof to facilitate removal of ashes from the ash pit 9, and a door II is provided for this opening. Air may beadmitted by opening door H or providing it with conventional damper-controlled openings. A suitable'gas or like burner I2 is provided in the top of the ash pit directly beneath the lowermost grate 7d.

A tin can compartment 13 is provided within the front portion of the combustion chamber above the grates, and this compartment is open at the top and has a forwardly sloping grate M at the bottom thereof. A further opening 15, provided in the front of the housing, communicates with the lower portion of the can compartment and has a forwardly sloping bottom wall I 6 flush with the grate I l. The opening I5 is provided with a gravity-closed swinging door ll that opens outwardly, and suitable means I8 is provided to releasably hold the door I! closed.

The housing 5 has a top wall provided with a forwardly sloping forward portion formed with a large opening [9 closed by a counter-balanced swinging cover 20.

An elongated narrow horizontal slot 2| is provided in the back wall of the housing, either above the grates as in Figure 4 or below them as in Figure 6. A plate 22 is mounted at the top of this slot and has angular edge portions 23 that project into and outside the housing and form flanges that are spaced from the surfaces of the back wall and depend slightly below the slot to provide a fly entrance through which passage of light is prevented. The chimney 6 may be made of angular form to prevent entrance of light therethrough into housing 5 so that the flies will not be likely to escape through the chimney before being consumed by the flames from the burner 12 and the burning trash.

While the incinerator may be constructed of any suitable material and may be portable, the housing is shown as constructed of concrete upon a concrete base 24 embedded in the ground.

In use, the cover 20 is opened and the garbage and trash are deposited in the housing so that all tin cans are placed in the compartment 13. Most of the garbage and combustible trash will be deposited on the top grate 1, and it will be noted that the grates gradually increase in fineness from top to bottom. As shown, the grates embody parallel grate bars, and the grate bars of the grates are alternately arranged at right angles to each other. Also, the spacing of the bars of the successive grates diminishes in a downward direction. When necessary, the burner I2 is used to ignite and/r consume'the garbage or trash, and asthey burn and fall'from one grate to another they scatter so as to be effectively consumed. The flames and heat pass through grate I4 into the compartment l3 sons to consume any garbage or trash therein and subject theitin-oans to a heat treatment whose efiect is .to render the cans more easily destructible by rusting and crushing. When the securing means 18 :is X6- leased, the cans will fall from the compartment l3 by gravity, forcing the door I! open and being deposited outside the incinerator.

From the above description,.thoseskilledinthe art will readily understand Land appreciate the construction, operation, and advantages of the invention. Minor :changes in details illustrated and described :are' contemplated; such as fall within the spirit of -:the invention as claimed.

What I claimis: 1. An incinerator comprising a housing diaving 1a topchimney and :a top opening in front of'the chimney .-for :the' introduction .of material to be consumed, :a-closure for saidopeninazazgratezconstructiori dividing the ihousingrinto an upper com- :bustion chamber and ia'lower ash pit, means defining an o'penetop tin can compartment in the front of the combustion chamber above the grate construction and spaced from and below said top opening, said means including a grate forming the bottom of said compartment and sloping to the front of the housing, the housing having a front discharge opening for said compartment provided with a, forwardly sloping bottom wall flush with said grate, and a closure for said discharge opening.

"2. The construction defined in claim 1, wherein the grate construction embodies a series of spaced superposed grates which progressively increase :in fineness downwardly, said last-named grates comprising spaced parallel grate bars, the grate bars of the successive superposed grates being alternately arranged at right angles to each other.
