3 Claims. 1

This invention relates to incinerators, and

more particularly to the combination of a trash burner and incinerator for garbage disposal.

The principal objects of the invention are to providea'trash burner having a garbage disposal compartment whereby the burning of the trash will dehydrate or dry out the garbage so that suchgarbage may be burned in the trash burner;

to provide a mounting forthe garbage container whereby the container may be rotated to dump the garbage after it has been dehydrated into the burner compartment; to provide means for applying additional heat above the garbage container in the fire box; to provide a fire chamber spaced from the housing of the burner to provide insulationfor the housing; to provide a mounting for the grate in the trash burner which may be rotatedto cause the ashes to filtrate therethrough; to provide draft to the fire box of the burner; and to provide a device of this character simple, economical to manufacture and efficient in operation. v

In accomplishing these and other objects of the present invention, I have provided improved de- .tures-oflmyinvention comprising a housing having-a rear wall 2,.front 3, sides'd and:5,'and top .6. The-top-ttisprovidedwith a forwardlyslopingrportion 1 provided with a'door 8 hingedto ithe-stop-firasindicated at fl. The housing is preferably madeof sheet-metal and fastened at the corners by providing flange portionsby suitable .means, such as welding, bolting orthe like. The .top-is fianged tofit over the outside edges of the housing and the frontiportionofthe flange sloped to accommodate the hinges 9 (Fig. 1)

Located within-the-housingis afire chamber 40 having :a rear-wall H spaced from the-rear wall .2 of -.the;housing'and; sidesiZand i3 spaced Kansas City, Mo., assignor to Aeco Manufacturing a corporation of Missouri Application November 9, 1945,'Serial No. 627,574

(30., Kansas City, Mo.,

from the side walls 4 and 5 to form an insulation space around the fire chamber. The top of the rear wall H is provided with an outwardly turned fiange 14 for attaching to the wall 2, and the sides l2 and I3 of the fire chamber are fastened at their bottom edges to the front wall of the housing by lateral flanges l5 .as best illustrated in Fig. 2. It will be noted that the fire chamber is thus spaced from the rear and side walls of the housing so as to eliminate excessive heat through the outer wall of the housing. A wall it is attached to the top 5 of the housing by welding or other suitable means as indicated at I1 (Fig. 2) and spaced from the top to form an insulation space to prevent excessive heat from reaching the top '6. A smokestack i8 is provided which extends through'the top 5 and intermediate wall F6 to the fire box It) for the elimination of smoke and fumes therethrough. Located within the housing and forming a bottom for the fire chamber i0 are grates i3, 29 and 2|. The grates l9 and 2| have their rear ends extending through the wall .H of the rear of the fire box andare attached to the rear wall 2 of .the housing by brackets 22 and 23. The brackets maybe secured to the rear wall 2 in any. suitable manner, such as by welding or bolting. The front ends of the brackets are attached directly to the front 3 by brackets .24 and 25, the front and rear brackets forming a suspension for the fire chamber in the housing. The grate 20 is provided with a central rod 25 rigidly secured to a frame 21 which comprises slide rods 28 and 29 and-end portions 3i} and Si. The rod 26 extends through the rear wall ll of the fire chamber and through the front wall 3 of the housing. The rear endoftherod is loosely mounted in a bracket 32 secured to the rear Wall 2 of the housing and the forward end of the rod 25 extends through the wall 30f the housing and is provided with a .handle '33 rigidly secured to the rod in any suitable manner for rotation of the grate 20 to cause sifting of the ashes therethrough. While the grates are formed so that ordinarily the ashes will sift therethrough without assistance, in burn- ,ingof magazines or like articles it may be necessary to stir up the trash by shifting of the grate.

While I have shown only the central grate as rotatable, it will be obvious that all of the grates could be rotated if desired without departing from the spirit of my invention.

Located within the fire chamber preferably substantially to the rear thereof and above the hire grate, is a garbage receptacle 34 mounted on 3 the sides I2 and I3 of the fire chamber by brackets 35. The brackets are flanged as indicated at 36 and shaped to form a V-shaped bearing 31 for the garbage receptacle.

The garbage receptacle 34 is cylindrical in form and preferably has ends 38 secured to a shaft 39 which extends through the ends 38 at substantially the centers thereof. The receptacle is provided with longitudinal partitions 40 dividing the receptacle into compartments 4|, 42, 43 and 44. The outer edges of the partitions 40 are turned laterally to form flanges 45 so that they will fit in the ends 38 of the receptacle which are also flanged as indicated at 46 (Fig. 1). The flange 45 will also aid in retaining the garbage in the compartments. The shaft 39 is preferably substantially square as best illustrated at 41 (Fig. 2) and the ends extending through the cylindrical ends 38 of the receptacle are adapted to engage in the V-shaped bearing 3'! of the brackets 35 so that the edges of the shaft fitting in the V-shaped groove will prevent the receptacle from rotating until moved by the operator as later described.

A bottom 48 is provided for the ash box 49 having a door 50 hingedly connected to the front wall 3 by hinges 5| and having a handle 52. Formed integrally with the bottom 48 and extending downwardly therefrom are legs 53 and 54. While I have here shown the legs as solid and extending across the front and rear of the housing, any suitable legs may be provided. Brace bars 55 are provided at each corner of the bottom of the housing to lend rigidity to the device.

Perforations 56 are provided in the sides 4 and 5 of the housing to allow air to enter the ashpit to provide a draft while burning the trash on the grates. If desired, the door 50 may be opened to add additional draft to the fire chamber. A lug 51 is provided in the lower corner of the door 50 to extend slightly beyond the side 4 of the housing. A latch 58 is pivotally mounted on the side for the housing as indicated at 59 and having a slot 60 in the outer end thereof adapted to enash pit is raised for cleaning out the ashes, the locking member 6| may engage in the notch 62 of the lower edge of the door as best illustrated in Fig. 1.

Extending through the side 5 of the housing and the side ['2 of the fire chamber is an elongated burner 63 preferably adapted for the burning of gas as fuel to dehydrate the garbage in the Trash, such as paper or other dry material, may placed on the grate in the fire chamber through bage for drying, said rack chamber has dehydrated or dried the garbage sufiiciently to allow burning thereof, the receptacle may be rotated by the hand of the operator to dump the dehydrated garbage onto the grate in the fire chamber for burning. The next compartment of the receptacle may then be available for further storage of garbage for dehydrating.

To facilitate burning of the trash in the fire chamber the center grate 25 may be rotated by the handle 33 and also to sift the ashes to the ash chamber. The ashes may be removed from the ash chamber through the opening 6! in the front of the housing by raising of the door 50.

While I preferably form my device from sheet metal or the like, it will be obvious that any suitable material may be used and the various parts flanged and secured together in any suitable manner.

My device may be adapted for either inside or outside burning of trash and wet material. When it is desired for operation in an enclosed space, the smokestack is available for disposing of fumes or smoke.

It will be obvious from the foregoing that I have provided an improved incinerator in which dry material as well as wet material may be disposed of by one operation.

What I claim and desire to secure by Letters Patent is:
