GARBAGE AND REFUSE INCINEBATOB.

' Application filed January 8, 1923. semi m. 811,364.

To all whom it may concern:

Be it known that Pmn W. Tnnmonx and CARL BARKJIAUSEN, citizens of the United States, residin at Milwaukee, county of 5 Milwaukee, anc l State of Wisconsin, have invented new and useful Improvements in Garbage and Refuse Incinerators, of which the following is a specification. Our invention relates to improvements in 1 garbage and refuse incinerators.

The object of our invention is to provide an improved incinerator which will be odorless and which is capable of utilizing as fuel, oil, coal dust or wood; also to provide an I automatic system for preh ating the garbage or other refuse, feeding it into the combustion chamber, withdrawing unburned gases from above the material and feeding such gases through the fire, whereby the obnox ions gases may be wholly consumed and the products of combustion finally delivered through the stack in a substantially odorless condition.

In the drawings":-- v Figure 1 is a vertical sectional view of an improved incinerator embodying the invention, the section being drawn to a plane which includes the axes of the return flues for burning the gases.

Fi ure 2 is asectional view at right angles to Fig. 1-drawn on line 2--2 of Fig. 1.

Figure 3 is a sectional view drawn on line 3-3 of Fig. 2.

Figure 4 is a sectional view drawn on line 4-4 of Fig. 2. A

Like parts are identified by the same reference characters throughout the several views. I

In the drawings, A indicates sliding doors through which the material is delivered to the incinerator into hoppers B.

G are ducts for the return of gases to the fire, D are grates disposed between the upper and lower marginsof the hopper and inclined downwardly toward the walls B to form' upper and lower portions of the hopper, E are inclined grates and F are dumping grates. G is a conveyor for the ashes and incombustible material dropping from the combustion chamber H. I is the chimney to which communication is had through. the openings I and I".

The walls B .of the hoppers Bsubdivide the hopper space into 'two sections. The material, as it dries and bakesinthe hopper sections, slides down along the walls B until 1t passes the grates D, whereupon it drops upon the auxiliary grates D' which are adapted to tilt and deliver the material into the fire-pot and. indirectly the grates D assist in such regulation .by directing the materials toward the inclined walls B.

The ducts are equipped with suction fans for positively withdrawing the gases from the upper portion of the hopper chamberand delivering them into the ash-pit un- =derneath the fire-pot, i. e., underneath the gratesE. Such fansare indicated at K.

The blast of air and gas delivered by the fans through the horizontal runs C of the ducts G produces an aspirating-efi'ect in the. auxiliary ducts C" which take the gases from beneath the inclined grates D. This aspirating efl'ect-is increased by baflies L which extend obliquely from one side parti'ally across'the lower end of each of the ducts C. Y

The heat of the fire in the combustion chamber H is relied upon to dry out the material in the hoppers B. The material in so the lower portion of. the hoppers between the inclined grates D andthe tilting grates D becomes very thoroughly dried. The walls B define a closed hot chamber above "the arch I this chamber having no inlet and i the chimney outlet I" being intended merely to relieve the chamber. from internal ressure due to heat; Therefore, the wa B may be raised to such a temperature that I material falling thereon isvery rapidly dried and brought into condition for burn ing and as this material passes most readily downwardly'to the portion of the'hopper below the grates D, the other materials are directed by said inclined these hot walls B so that substantially all material is brought into contact with or. close proximity to said walls before reaching the fire-pot. Y

To support combustion in the fire-pot the grates D toward" fuel is delivered thereto under air pressure.

It is, therefore, possible to use oil, or other liquid fuel, or to use solid fuel which, if desired, may be'in .finely subdivided form.

We claim: 3 1. In a garbage incinerator, the combination with a fire-pot, of, a superposed receiving hopper having an inclined wall and a co-operating'wall, said inclined wall being inclined downwardly toward said co-operating wall, and a grate downwardly and inwardly inclined from the co-operating wall toward the inclined wall intermediate the upper and lower margins of said hopper,

- inclined hot a through which material may be'delivered into the hopper, tilting grates disp0'sed between the margins o'f'said arch and said tions and'inclined inwardly from the in-' thereby to subdivide said hopper into upper and lower portions. 7

2. In a garbage incinerator the combinationwith a fire-pot, of a superposed receiv-c ing hopper having inner walls downwardly and outwardly inclined and outer walls, and grates downwardly andinwardly inclined from the outer walls of the hopper toward said inner walls at points between their upper and lower margins, said grates partially subdividing the hopper intoupper and lower portions. 1

'3. In a garbage incinerator, the combination with a fire-pot, ofa superposed receiving hopper having inner wallsdownwardly and outwardly inclined and outer walls, and grates downwardly and inwardly inclined from the outer walls of the hopper .toward intermediate portions of the inner walls, said grates partially subdividing the hopper into upper and lower portions, and

inclosing walls, said grates vbeing adapted in one position to su port material in the path of the flame an gases of combustion coming from the fire-pot and adapted in another position 'to permit such material- 7 to pass from the hopper into the fire-pot,

and co-o rating grates partially subdividingthe opper into upper and lower secclosing walls to thereby direct material from the upper section to the lower section along the surfaces of said inclined hot plates and away from said inclosing walls.-

5. In a garbage incinerator thecombin'ation of'an enclosing chamber provided with a- "grated fire-pot m its'lower portion, a

superposed arch spaced from.walls of the enclosing chamber at the respective sides H of the arch, tilting grates insaid spaces 2 adapted to regulate deliveryof material to the fire-pot from the space above the grates, upwardly convergin hot plates above the arch, and means material from the upper portion of the chamber inwardly and downwardly toward said hot plates, whereby such material is caused to slide downwardly along the hot plates to; said gratesv 6. Ina garbage incinerator the combination of an enclosing chamber provided with. v r a grated fire pot in its lower portion, a

superposed arch spaced from.walls ofthe enclosing chamber at the respective sides or delivering of the arch, tilting grates in said spaces adapted to regulate delivery of material to the fire-pot from the space above the grates,

upwardly converging hot plates above the arch, means for deliveringmaterial into the upper portion ofthe chamber downwardly upon and along said hot plates to said grates, and a set of feed regulating grates controlling the downward movement of material along. said hot plates.

7. In a garbage incinerator the combination of an enclosing'chamber provided with a grated fire-potin its lower portion, a-

superposed arch spaced from walls ofthe, enclosing chamber atvthe respective sides of the arch, tilting grates in .said spaces adapted to regulate delivery of material to the fire-pot from the space above the grates, I

upwardly converging hot "plates'flabove the arch, and means for delivering material into the upper portion of the chamber down- I wardly upon and along said hot plates to said grates, and aset of feed regulating grates controlling the downward movement of material along said hot plates, said. enclosing chamber walls being provided with ducts leading from theupper portions of the chamber downwardly topoints beneath the fire-pot, whereby gases of combustion maypaseEthrough the material above the tilting grates and then downwardly with vapors from such material to be delivered through the fire from below.

. 8. In a garbage incinerator a chamber subdivided by into an upper material receiving hopper section, a lower material supporting hopper section, a fire-pot, and an ash pit having ducts leading,'respect-ively, from both hopper sections to the ash-pit, and power partition walls and gratings driven means for maintaining a forced cirthe 7 material in the hopper sections and. downwardly in said ducts. ,1

v 9. In a garbage incinerator a chamber subdivided 'by artition walls and gratings into an upper opper section, a lower hopper section, a fire-pot, and an ash-pit havculation upwardly from the fire pot through ing ducts leading, respectively, from both hopper sections to the ash-pit, and power mentioned ducts and provided with a bafile driven means for maintaining a forced ciradapted to utilize the aspirating efiect deculation downwardly in said ducts, oneof 'veloped by the impeller to cause a. down- 10 said ducts being provided with a power ward'circulationin the cooperating duct.
