una i. Wessel, las Cay, Miss. Application January 18, 1351, Serial No. 206,535 o 'sautant-is) 'lhis invention relates to refuse disposal units used for 1 for admitting air to the unit and preventing escape of fumes and odors into the room or area in whichthe disposalunitisbeingused.

Another object is to design a disposal unit provided with an automatic check damper which is automatically actuated as the unit is in operation to regulate the draft and prevent overheating when pa rs or other highly combustible material is being burnetfV A further object is to provide a unit having `a bale cylinder with a perforated basket or container suspended therein to provide a full length annular sir space between said cylinder and container, rmitting cool an' to dow downwardly to the bottom o the unit and circulate around the consumable material in the container and provide for maximum drying action, and the eva ration of moisture in the material to the end that slow urning trash and garbage will burn more readily and evenly.

Still a further object is to provide a com gact, neatappearing disposal unit which can be placed in e kitchen, basement, oiiice or other art ot the house o r establishment, and which will ctfectively consume rubbish, garbage and other combustible refuse placed therein. l

A further object still 'is to provide a compact, ecient disposal unit having constructional characteristics conducive to rapid combustion of materials not easily burned, and which will not, give od excessive heat into the room in which the unit is located.

A further object'isto provide nesting, removablefan portable ash containers into which the ashes fall-as the grate is actuated so that there is very little spread of ash dust or spilla e in the base of the unit. fi

Another o ject is to provide a disposal unit provided with a top extension for the cabinet `with an inclined double door arrangement for use in chargin the combustion cylinder, igniting the materials, an admitting cool air to the upper interior of the casing. l

With the above and other objects in view, the present invention consists in the combination and arrangement of parts, hereinafterv more fully described, illustrated in the accompanying drawing, and more particularly pointed out in the ap nded claims, it being understood that changes may made in the form, size, proportions, and minor details of construction, without departing from the spirit, or sacrificing any of the advantages of the invention.

In the drawings: A

Fig. l is a front elevational view oi my disposal unit, the front wall being broken away to show the ash containers.

Fig. 2 is a vertical, part sectional, side elevational view of the unit, the broken lines showing the feed'door in raised position. he d Re erring now more particular' y to in which l have shown the preferred embodiment o my invention, the letter C indicates a sheet metal cabinet frt, andside all8,9,10and1175 comprising on nar w s i. ilow upwardly through the smoke pipe to atmosphere.

respectively, and an extension 12 forms a closure for the upper end of the casing, the top being u wardly inclined as at 13, and an opening 14 is provi in this inclined area.

A feed door member 15 is hingedly connected to the 4top of the extension by hinges 16, and an opening 17 is l due to the air circulating over and around it with the cabinet.

' container A and said member is rovided in the feed door with an auxiliary door 18 Kingedly connected to the lower edge of the door 15 at the point19, and handles 20 are provided on the door 18 for ea'oganipulationthereof. The lower edge of the a r 18, which is adjacent the pivot 19, is spaced above e main door to form a slot 41, through which air from the exterior may enter the upper portion of the A transversely disposed plate 21 spans and closes the cabinet.

A relatively large ash pit door 24 is provided on the front wall ofthe casing2 and is provided with a transparent sight glass 25, the casing walls being insulated as at 26 to conserve heat in the cabinet and prevent excessive heat entering the room in which the unit is located.

An lair baille member 27 `is interposed between the perforated combustion receptacle 28 andthe walls of the casing, the upper end being ilared as at 29 for securing it in sition in any desired manner andr L-shaped su port ugs 30 Iare provided on the combustion receptace and engage the top of the air baille member for suspendnet directly below `the lower end o the perforated combustion cylinder, said gratebeing pivotally mounted on the shaft 31, and alink 32 is pivotally `connected to said grate at the point 33, the upper end of the vlink being connected to a crank 34 which is mounted in the wall of the cabinet with a crank handle 35 for easy manipulation of the grate.

A burner B opens through the net directly adjacent the sight glass 25.

A smoke pipe 36 o ns into the to? of the extension member 12 adjacent e upper end o the inclined area of the top, and an automatic dam r D is mountedin the back wall of said extension an comprises a housing 37 set in a suitable opening provided in the back wall of the extension,a damper 38 forming a closure for the open face of the housing and is pivoted as at 39 with a small weight or handle 40 on the lower end thereof to wall of the housing being open to permit passage o air therethrough, all as indicated by the arrows shown in Fig. 2 of the drawings.

The auxiliary door 18 has its lower end spaced above the face of the feed door 15 to provide an air inlet draft slit or o ning therebetween so that cool air iiows into the cabinet between the air baillemember and the combustion receptacle, and thence to the smoke-tine, all las indicated by the arrows shown in Fig. 2 of the drawings.

, The lower endof the air baie member 27 is disposed in closely spaced relation to the upper end of the ash as at 42 to accommodate the burner.

The containers Aare removable through the ash pit door 24 and by utilizing two ash containers, one container will always be in ition while the other is being emptied. 'Ihe grate G is c eaned by rotation of the handle 35; this `rocks the grate as indicated in broken lines in Fig. 1 to dislodge and discharge ashes and other debris from the grate into the ash container;

` Rubbish, garbage and other combustibles, either wet or dry, are fed to the combustion receptacle, either through the feed door 15 or the auxiliary door 18, and if the trash is dry, no heat source is needed, it being merely necessary to ignite papers or other dry trash with a match through .the auxiliary door. However when the garbage is wet and so the burner B isignited. This aids in the drying with minimum odor, as moderately moist refuse will dr y fairly well under normal draft conditions bumer'burning at a low llame which does not contact the refuse. High ame .contacts the refuse and ignites it and as the contents are consumed, the smoke and gases When the combustion receptacle is filled with paper or other highly combustible material, the smoke pipe temperature rises very quickly,'and this smoke pipe temperature is automatically controlled by the check damper l) which about the pin 39 to a more opened, in-

side wan iief the eabiclined osition as indicated in Fig. 2 of the drawing, permitting cold air to dow into the smoke pipe through the baille box inlet, all as Yindicated by the arrows shown in Fig. 2 of the drawings. The damper 38 is normally slightly open and when the smoke pipe temperature an d consequently the draft pressure increases, the rush of air through the damper housing D acts to pivt the weighted damper 38 to admit a greater volume of air. The perforated combustion receptacle 28 insures maximum drying surface and free air circulation, and rovides for even burning so that all combustible refuse is completely consumed and reduced to clean ash suitable for use as a fertilizer.

When the feed door l5 is opened for charging, air is admitted to the cabinet through the opening 41; however, it will be noted that the air enters at a point below the smoke pipe opening into the cabinet so that it will flow rearwardly and upwardly, carrying with it any smoke or gases rising from the material in the combustion cylinder, consequently, there is no smoke or leakage into the room, and

204 this also holds true for air admitted through the draft inlet or the auxiliary door when vthe door 15 is closed.

From the foregoing, it will be obvious that I have perfected a very simple, practical and effective disposal unit which can be easily and econorriically manufactured and assembled, which is of neat and pleasing appearance, and

k which completely consumes all combustible material.

What I claim is:
