GARBAGE-FURNACE.

SPECIFICATION forming part Of Letters Patent No. 543,134, dated July 23, 1895. Application filed June 28,1894. Serial No. 515,916- (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM S. HULL, a citizen of the United States, residing at Dallas, in the county of Dallas, State of Texas, have invented certain new and useful Improvements in Garbage-Furnaces, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in garbage-furnaces for the cremation of garbage, night-soil, and the like; and it has for its objects, among others, to provide a furnace that shall be simple, durable, cheaply constructed, and easily attended and fired, and by which the moisture from the material being treated shall be completely evaporated and the material thus deprived of its moisture rapidly burned. Provision is made for the rapid evaporation of the moisture from the material, and for the easy handling of the material before and after it is introduced into the furnace.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be specifically defined by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon,form a part of this specification, and in which- Figure lis alongitudinal vertical section through the improved furnace. Fig. 2 is a vertical cross-section on the line 2 2 of Fig. 1. Fig. 3 is a front elevation thereof. Fig. 4 is a horizontal section on the line 4 at of Fig. 3 looking down. Fig. 5 is a cross-section on the line 5 f Fig. 2 looking down. Fig. 6 is a detail in top plan showing the dump-door, the platform-door being removed and parts broken away. Fig. 7 is a sectional plan of the dump-box and its slide-doors and their guides.

Like letters of reference indicate like parts,

. throughout the several views.

Referring now to the details of the drawings by letter, A designates the furnace proper, built of suitable material upon proper supports, all parts thereof which come in contact with the'fires or extreme heat being laid up with fire-brick or analogous material. The furnace in its ground plan is substantially in the form of a cross, as seen best in Figs. 4 and 5.

A is the chimney or stack of suitable form,

which maybe extended to any desired height.

B is a double inclined driveway supported upon suitable uprights B, as shown best in Fig. 3, and in this platform or driveway, at a point directly over the dump-box is a hinged door or gate B as seen best in Figs. 2 and 5, and directly beneath the said door is the top door 0 to the dump-box, which is shown in this instance as hinged (see Fig. 6) and which may be of any desired form of construction. This dump-box D is supported upon the brick arch D, which forms the roof of the central combustion-chamber of the furnace, and upon opposite sides it is provided with the doors D which are mounted to slide in suitable guides d as seen best in Fig. 7, which guides are formed by plates (1, which are secured to the inner faces of the other sides of the dump-box, as is clearly seen in said Fig. 7. These doors are designed to be raised and lowered in their guides by means of a rope or chain d suitably connected therewith, as shown in Fig. 2, and suspended from a crane D supported above the top of the furnace and braced by the brace-arm 01 as shown. With the doors B and 0 open, these side doors maybe easily raised. They are preferably provided with a plurality of perforations near their lower end as shown at d" in Fig. 1.

- The interior arrangement of the furnace is shown in Figs. 1, 2, and 4. From these views it will be seen that the dump-box rests centrally upon the arch D',beneath which is the central combustion-chamber E, which is provided with the oppositely-disposed dues or passages e, as seen in Figs. 1, 2, and 4.

At opposite ends of the furnace are the grates F of any desired form and upon which the fires are started, the products of the combustion passing throughthe course indicated by the arrows in Figs 1 and 2.

lVithin the combustion-chamber E is an inclined support or platform G of bricks, which, as shown best in Fig. 2, are laid loosely in pyramid form without mortar, so as to provide crevices for the absorption of fluids from the material as it finds its way thereto from the dump-box, either through crevices in the walls thereof or through fissures, as indicated by dotted lines in Fig. 1.

At opposite ends of the furnace are provided openings g, as shown best in Fig. 1, provided with suitable closures, and through which the attendant may rake the material down toward the ends after it leaves the dumpbox. Suitable openings h are provided for cleaning out the ashes beneath the grates, as indicated in Figs. 2 and 4.

Upon opposite sides of the central combustion-chamber and between the same and the grates I arrange the pyramidal evaporatingsurfaces H, which are formed of bricks or analogous material laid loosely in pyramidal form without mortar, except the lower course or courses, which are laid in mortar upon an inclined bed I, as shown best in Fig. l. The surface of the bricks presents a plane following the contour of the brick as the set-outs are made to assume the pyramid form, as shown, so as to the better conduct the liquids throughout the greater surface and provide for the more complete evaporation thereof. It will be seen that while the said bricks are set upon beds inclining from the outer portion toward the central arch the upper surface of the platforms are inclined in the opposite direction, so that the material, as it falls from the dump-box, will find its way or be easily raked down onto the grates, which are located at the outer edges thereof, as shown best in Fig. 1.

In the extension A of the furnace is arranged an auxiliary grate I, as seen best in Figs. 2 and 4, which is located at the end of the inclined platform G, as shown, and which is provided with a side opening '6, through which it may be fed.

Beneath the grates and central combustionchamber is a conduit or tunnel J, as seen in Fig. 2, through which the products of combustion and odors are conducted, as indicated by the arrows, to and up through the stack A. A suitable opening j, closed by a suitable closure, is provided for cleaning out the stack when occasion requires. Such is shown in Figs. 2 and 4. The bed of the platform G is provided with small passages g, as seen in Fig. 2, through which the moisture or fluids may trickle, should any pass through the interstices of the platform without being completely evaporated.

WVith the parts constructed and arranged substantially as above set forth the operation is as follows: Fires being started in the grates,

the carts containing the garbage are driven up the inclined driveway and the doors B and 0 opened, the side doors D being closed and the material dumped into the dump-box. The doors are then closed. The material is allowed to remain in the box as long as of bricks of the platforms G and II and gradually carried to the central combustion-cham' her and the tunnel or conduit, where final evaporation takes place. No fluid ever reaches any of the grate-bars, and the construction is such as to keep up uniform evaporation, so thatin case of flood or dearth the fires are doing similar service. After the garbage has become somewhat dried in the dump-box, one or the other orboth of the side doors are raised and the material allowed to fall upon the pyramid floor or floors H, from where it is easily handled byhoes or rakes or books, always pulling downward and forward until it finally reaches the large grates, where complete combustion takes place, none of the garbage comingin contact with thepermanent fires. At times verylittle fuel will be used, except such as is dried out of the garbage. The flames pass up the inclined pyramids, thence through the dues under the brick arch into the central combustion-chamber and down the incline in the combustion-chamber, (at this point drying such fiuidsas are brought through the fissures in thewalls) thence over the secondary fire in the grate I, and, returni-ng under it, passing through the tunnel J, where final combustion of the gases and evaporation of the fluids that find their way into the tunnel takes place. From the tunnel the remaining inoffensive gases pass into the stack and out at the top thereof.

Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

What is claimed as new is 1. In a garbage furnace, the combination with a platform of bricks arranged loosely to absorb fluids, of means for feeding material thereto and means by which the material is destroyed, said platform being arranged to be subjected to the heat from the fire and combustion chambers, as set forth.

2. In a garbage furnace, the combination with a platform formed of bricks laid in inclined planes with crevices to conductfluids to evaporating points, of means for feeding material thereto and means as the fire chambers for destroying such'material, as set forth.

3. In a garbage furnace, the combination with bricks laid looselyin pyramidal form, of means for feeding material thereto, and means as the fire chambers for destroying such ma terial, said bricks being arranged to be subjected to the heat from said chambers, as set forth.

4. In a garbage furnace, the combination with bricks laid loosely in pyramidal form upon inclined beds, of means for feeding material thereto and means as the fire chambers by which the material is destroyed, said means being located so that the bricks are subjected to the heat therefrom, as set forth.

5. In a garbage furnace, the combination with central combustion'chamber, of an inclined platform therein composed of bricks set inclinedly and a base therefor having passages, the fire chambers upon opposite sides of said platform, and the flue leading beneath the base and communicating with the chimney, said passages being designed to establish communication between the space above the base and the flue below it, substantially as specified.

6. In a garbage furnace, the combination with the fire chambers and a central combustion chamber between the same, of pyramidal foraminous platforms upon opposite sides of the central chamber upon inclined beds the upper surfaces of the platforms being oppositely inclined to the beds, the walls of the central chamber having passages above said platforms and provided with openings communicating with the fire chambers, substantially as specified. V

7. In a garbage furnace, the combination with the fire chambers and a central combustion chamber, of an inclined platform within the central chamber, a base therefor with passages for the liquid a tunnel beneath the same and communicating with the stack, and pyramidal platforms upon opposite sides-0f the the platform in the central chamber, and means for introducing liquid matter into the central chamber, substantially as specified.

8. In a garbage furnace, bricks laid loosely in pyramidal form with inclined beds and the loose course or courses laid in mortar upon said beds, combined with means for feeding material thereto and with means as the fire chambers for burning such material, substantially as specified.

9. In a garbage furnace, a foraminous pyramidal evaporating surface having its upper face inclined oppositely from its bed, and the central chamber and its inclined platform, combined with means for feeding material to the above mentioned evaporating surface, a foraminous base and the fire chambers upon opposite sides of the said surface for destroying the material, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM S. HULL.
