INVENTOR. GLENN ENDECKEZ ATTQQMEYS United States Patent GARBAGE AND REFUSE INCINERATOR Glenn E. Decker, Topeka, Kans.; Hazel C. Decker, administratrix of said Glenn E. Decker, deceased Application March 30, 1956, Serial No. 575,189 1 Claim. (Cl. 110---18) This invention relates to garbage and refuse disposal devices, and more particularly to a garbage and refuse incinerator provided with means for crushing incombustible waste material, such as tin cans, and the like, for final disposal.

' The main object of the invention is to provide a novel and improved garbage and refuse incinerator which is relatively simple in construction, which is easy to install, and which provides thorough incrineration and reduction in mass of refuse material, so that the refuse residue occupies only a small volume and may be easily disposed of.

A further object of the invention is to provide an improved garbage and refuse incinerator which is inexpensive to fabricate, which is rugged in construction, and which is provided with efficient means for crushing noncombustible material, such as tin cans, or the like, after all combustible material has been consumed, whereby the residue is reduced to a very small volume .and may be readily collected and removed from the device.

Further objects and advantages of the invention will become apparent from the following description and claim, and from the accompanying drawings, wherein:

Figure 1 is a vertical cross sectional view of the garbage and refuse incinerator according to the present invention.

Figure 2 is a horizontal cross sectional view taken on the line 2--2 of Figure 1.

Figure 3 is an enlarged cross sectional detail view taken on the line 3-3 of Figure 1.

Referring to the drawings, the numeral, 11 generally designates an improved garbage and refuse incinator according to this invention, the said incinerator comprising a generally rectangular, upstanding casing 12. having a front wall 13, a rear wall 14, opposite side walls 15 and 16, a top wall 17, and a removable bottom drawer 18 which normally serves to receive residue material from the incinerator, the front wall 13 being provided with an access door 19 which may be opened to provide access to the drawer 18 for removing same from the incinerator. As shown, the front wall 20 of drawer 18 is provided with a handle 21 which may be employed to withdraw the receptacle 18 from the incinerator when it is to be emptied.

The lower marginal portions of the side walls 15 and 16 have secured theretorespective supporting tracks 22, slidably supporting the respective longitudinal side portions of the drawer 18.

The upper portion of front wall 13 is provided with an intake door 24 which is hinged at 25 to the lower edge of a refuse intake opening 26 provided in the upper portion of front wall 13, the door 24 being biased towards closed position by suitable spring means, such as springs 27 provided on the hinged rod 25 and being positioned to bias the door 24 counterclockwise, as viewed in Figure 1, namely, toward closed position. The door 24 is provided with side walls 28 extending through the aperture 26, whereby the door 24 serves as a chute, when in opened position, through which refuse material may be guided into the incinerator. The door 24 is provided with a suitable handle 29 for opening the door, whenever necessary.

The rear wall 14 is provided with an exhaust flue 30 located substantially opposite the door 24 and having mounted therein an exhaust blower 31 for creating a vacuum in the flue 30 to draw the products of combustio out of the incinerator through said flue.

A screen 32 is mounted in the rear upper portion of the incinerator, over the entrance to the flue 30 and extending downwardly a substantial distance, as shown in Figure 1, whereby solid-residue is prevented from entering the hue 30, and whereby only gaseous products of combustion are allowed to pass through the flue.

The walls of the upper portion of the incinerator are provided with refractory linings 33, said linings being of suitable refractory material, such as fire brick .or the like, whereby the upper portion of the incinerator defines a combustion chamber having at its lower portion downwardly convergent hopper means'34. Said hopper means 34 comprise downwardly convergent walls 35' lined with refractory material 33, one of said walls, namely, the wall portion adjacent the front wall 13'being provided with a gas burner 35 having an external control valve 36, as shown in Figure 1. The burner 35 is provided with a pilot burner 37 which is continuously ignited, and whereby the main burner 35 may be ignited by opening the main valve 36.

Designated at 38 are grates which are pivotally mounted in the bottom end of the hopper 34 on shafts 40 extending rotatably through the opposite front and rear walls of the top portion of a secondary hopper 42 below and communicating with the first hopper 34. Each shaft 40 and 41 is provided at its rear end with an actuating gear, the said gears being shown at 43 and 44, said gears meshing with an intermediate gear 45 mounted on the rear end portion of a transverse control shaft 46 extending rotatably through the front and rear walls of the discharge spout and through the front wall 13 of the incinerator, said shaft being providedxat its forward end with an operating handle 47 located below the main gas valve 36.

Rigidly mounted in the casing of incinerator 11 subjacent to the discharge spout 80 is a residue receiver 81 having a downwardly convergent hopper portion 82 aligned with the discharge spout 80and provided with internal corrugations 83 extending longitudinally along the internal receiver wall 82.

As shown in Figure 1, the receiver 81 is provided with a horizontal bottom flange 84 which is rigidly secured to the respective front, rear and side walls of the casing of the incinerator 11, as by the provision of a vertical peripheral flange 85 on the member 84. The peripheral flange 85 is secured in any suitable manner to the respective vertical walls of the casing of incinerator 11, as for example, by bolts 86.

Secured to the top rim of the corrugated, downwardly convergent hopper member 82 is a spider member 87, said spider having the radial arms 88 which are fastened at their outer ends to the top rim of the receiver 81 and which merge with a central bearing disc 89, as shown in Figure 2. The disc 89 is formed with a central aperture which rotatably receives the top pivot stud 90 of a downwardly flaring, corrugated crusher cone 91 having an axial bottom pivot stud 92 pivotally supported on an eccentric disc 93, which in turn is secured to the shaft of a vertical electric motor 94 secured by bracket arms 95 to the bottom of the plate member 84. As shown in Figure 3, the disc 93 is provided with a radial slot 96 which rotatably receives the reduced lower end 97 of the bottom pivot stud 92, the slot 96 being offset from the shaft of motor 94, shown at 98, whereby the rotation of disc 93 causes the lower portion of the crusher code 91 to be eccentrically rotated around the interior of the corrugated, downwardly convergent hopper 82 around the axis of motor shaft 98, which is offset from the axis of the hopper 82-, as is clearly apparent from Figures 1 and 3.

Therefore, when the unconsumed residue resulting from the combustion of refuse material in hopper 34 drops into the corrugated hopper 82, as a result of the opening of the grates 38 and 39, energization of motor 94 causes the crusher. cone 91 to oscillate and rotate eccentrically in the downwardly convergent corrugated crusher hopper 82, causing any compressible material, such as tin cans, or the like, to be crushed to a relatively small size, sufficiently small to pass between the bottom end of the crusher cone 91 .-and the lower portion of the corrugated, downwardly convergent hopper wall 82. The crushed resi' due drops into the-collection receptacle 18, and is eventually removed after the container 18 becomes substantially filled.

What is claimed is:

In a garbage and refuse incinerator of the type comprising a casing, a door in the upper portion of the casing for admitting refuse" into the casing, a burner in the intermediate portion of the casing, a rotatable grate in the casing below the burner, and hopper means in the casing above the grate, the improvement comprising a generally conical, downwardly convergent compression cham- ,4 her mounted below said grate and communicating with said hopper means, said chamber being provided with internal corrugations, an upwardly convergent, generally conical, corrugated compression member in said chamber, means pivotally supporting the top end of said compression member substantially centrally in the top portion of the chamber, an eccentric disc journaled below said compression member, means drivingly connecting said eccentric disc to the lower end of said compression mem her, and an electric motor mounted in the casing and drivingly connected to said eccentric disc, whereby said compression member will gyrate in said compression chamber and at its lower portion will move toward and away from the lower internal wall portion of said compression chamber responsive to energization of said motor, said compression chamber being open at its bottom to define a discharge passage.
