Specification of Letters Patent.

GARBAGE-INCINERATING FURNACE.

' Application filed April 23, 1912. Serial No. 692,847. z

To all whom it may concern:

Be it known that I, ED'WARD SMITH, a citizen of the United States, residing at Huntington, in the county of Huntington and State of Indiana, have invented new and useful Improvements in Garbage-Incinerating Furnaces, of which the following is a specification.

My inven'tionrelates to i'ncinerating furnaces for burning ordinary refuse and garbage, and consists in certain improved features of construction, which will now be described in connection with the accompanying drawing in which,

Figure l is a vertical section, taken approximately on line AA of Fig. 2,'and a partial elevation of a furnace constructed according to my invention, and Fig. 2 is a horizontal plan section of the same.

In my experience with incinerating furnaces as heretofore constructed, particularly with those built according to Patent No. 971,548, to McGuire, I have found that they have to be practically rebuilt every time they are allowed to cool down. To avoid this objection I have devised the construe tion shown, which permits of expansion and contraction of the walls without injury.

My improved furnace consists of a hem'ispherical outer shell 1 of common brick, and a hemispherical inner shell or lining-2 of fire brick, the outer radius of the latter being less than the inner radius of the former, whereby an air space 3 is left between the outer shell and lining,'permittiug the latter to expand under the heatof the furnace when in operation, and to contract when the furnace is shut down, without injury to'itself or to the outer shell which, of course, is likewise free to expand and contract by itself under such temperature variat-ions as it is subjected to; The floor or hearth' of the furnace is also of fire-brick and is slightly dished toward the central opening 5, from beneath which runs an arched or circular drain 6 to the outside of the furnace.

7 is a door through which ashes, etc., are removed.

s is the outlet-from the hearth a ate chimney 9.. I, i 10 IS a branch due or drain, communieat Patented se sis, rare,

"1a is the hopper through which the material is introduced, falling, of course, onto the floor or hearth over the opening 5.

The furnace being already in operation,=

the moisture is at once dried out and then the material is burned. The ashes and in- 5 An incinerat-ing furnace consisting of an outer hemispherical shell having'a horizontal base, an inner hemispherical linin spaced from said shell, a chimneyconnecte to the shell and base, a hearth on said base having a central opening which' communh cates with an opening mthe base, sald' chimney adjacent its base being formed with a downwardly inclined outlet that extends through the said lining and has the wall formed by its bottom extending adjacent the hearth, said base being formed with an arched drain which at one end communicates with said base opening and at its opposite end extends through the periphery" of the base, a. branch drain formed in't-he base that extends from the base opening and 'is curved upwardl to extend into the outlet at the end thereo 4 adjacent the hearth, and

a fire box at one side of the hearth.

In testimony whereof 'l have hereunto set my hand in presence of -two subscribing witnesses. v
