Specification of Letters Patent, 'Pgnted 'Jaim 3,1, 1922;

To all fui/omi t may concern.'
Be it known that we, lViLLrAM Fn'rznn,
JOHN G. Fnnnns, and Orro lfliinro'rr, citif zens of the United States, residing at Springfield, Springfield and Marion, respectively, in the counties oi" tianganioin Sangamon, lVilliamson, 4respectively and State ot illinois, have invented kcertain new and useful lmprovements in Incinerators, of which the following is aspeciication, reference being hadtherein to the,accompanying4 drawing. l
This invention relates to improvements iu incinerators, and is. designed more r`particularly for use in connection with'the burning of garbage, city refuse, and the like.
Y In the burning ofgarbage, as heretofore practiced, in plants designed to take care of the garbage of towns or cities, the garbage has been deposited usually on grated receiving bottomsfand dried and burned. lin most instances, the drafts are in an upward direction and are designed to be carriedor forced through,thepiledup garbage. Yllhile it has been suggested in the past to .employ what 1is' commonly known las the starting grate, and to thereafter rake portions oit dried material Jfrom the garbage grate on to the Afire grate, it has not, as far as at present knowny to us, been suggested or,V proposed prior to kthe `present invention to utilize'this principle of drying .and burning under such conditions as will eliminate or prevent ythe escape of obnoxious vaporsor odors and fur ther4 the incinerators heretofore suggested` have been 4comparative]y "complicated, oi large proportions, especially .in va vertical direction, andhav'ebeen so constructed as `to require expert skill in manipulation. y
The object `oi the present invention is to produce an incinerator wherein an eiliective down-draft may be employed, the heated products of combustion passing over the garbage downward vinto the down-draft and vescaping into the up-take or chimney.I A further object of the invention isto provide anincinerator with a plurality of burning grates, a dumpingoor on the plane of and intermediate the grates and Ythe stoking opening so positioned that the operator can rake'th'e dried material. from the heap onto ing downward.
either grate for burning thereon. A fur.- ther object isto providean incinerator of the above suggested character with proper draftcontrolling means. Further objects joi the invention will beinentioned in the following speciiication,',andfwill be appreciated bythose skilled in this art.
ln the accompanying drawings, therefis shown one embodiment of the invention in itsfvarious details, butit is to be understood that changes `and variations may be made without departing from the nature, andr principle of the depictedstructure and invention.v f
, In. the drawings:
i Figure l is a `front eleva cinerator. I p .c Figure 2 is a longitudinal,horizontal section through-the line 2-2 of Figure "l, looktion or the ini- Figure 3 is a through the line 3 3 of'FigureQ.
rThe `furnace comprises substantially tour vvertical walls,'l, 2, 3 and 4, conveniently stayed and trussed by anchor rods 'and face longitudinal vertical section braces,fas indicated a't r'and 6. The r'front ot the furnace 1s -pr0videdwith a centrally disposed opening A having stoking .port or ports B, B. vOn oppcsite sides of the center there are openings C, C `for theashpit and grates,presentlyto be described. The c walls of the vfurnace areco'nveniently composed of l ayers,'the inner layer being of `refractory material as .at D, an interposed layer ofinsulatingmaterial at D and an outer casing'or shielding of masonry" as at D?. E represents the iooror bottom ofthe furnace, and F and F the iiregrates located at the iront in opposite corners leaving a material space between. These grates may f be of any convenientor recognized` form,
`and are margined at their forward and inner height of these curbs above the .grate bars maybe approximatelyn six inches. They inner wall of each curb is `sloping for poses presently to be described. The stoking opening A' flares at its innerend to permit a ywide lateral sweepv of the stoking iron.y
edges by shortA upstanding curbs f. The f Y ioo bounded by a curb g, suitably barred andY the front of the furnace as indicatedat it.V
I designates the lling opening or throat which is preferably located directly over the center of the furnace as indicated more particularly in dotted'lines Figure 2. The filling opening I is provided with a suitable cover J, Vwhich may be raised and permit the garbage carts to pass thereunder so that the contents may be properly dumped into the furnace through the opening I, the driveway ofthe furnace being indicated at K.
/While generally the structure has been referred to above, it is to be understood that the essentials of the Vfurnace are the relative positions of the grates, stoke hole and downdraft, with the central position of the receiving opening. Y It has been found, however, that the control in such a furnace is one of great importance, and therefore in the; combination the damper H represents an important factor. In the operation the garbage carts are driven over thel floor K, the top J being removed, and the contents are dumped into the opening I onto the receiving-floor E at the middle of the furnace.l
- Inthe first instance, or the starting, a lire is started on one of the grates, and the products of combustion, gases, etc., pass over the garbage heap located intermediate the down-draft opening, and the grate thereby drying the material and at the same-time V'crmsuming the gases and preventing obnoxious odors entering the chimney. After a sutlicient quantity of the garbage ina- Vterial has been dried it is7 raked onto the grate and the opposite grate may then be operated by raking the dried material thereon, or otherwise, andY both fires usedA to `-quickly dry and consume the garbage. The `stroke hole being centrally positioned be'- twecn the grates bothV are easily accessible for the employment of the stolring iron to draw the dried material onto the grates until A thc'- same is entirely consumed.v It maybe stated here that the advantage of the downdraft with fits association with the grates ,is that `,an action is acquired similar' to that ofthe open hearth furnace, all of the liquid ,being evaporated, none being allowed to es'cape vfrom-.the furnaceA Vbottom owing to the'lfa'ct that the bottom `is impervious and .the various ledges or ,curb interceptthe Vfor the incinerating purposes.
passage of any materials into the down-take or onto the grates except that which has been dried may be pulled and drawn onto the grates over the curbing thereabout. The furnace bottom represents a large superiicial area over which the garbage may be spread by stoling or otherwise,` and as the material dries out the same may be drawn from any part onto the grates as above stated. rlhe furnace is always a down-draft furnace, the products of combustion passing over the garbage and thereby the greater heat is employed to consume the gases and vapor as they pass towards the down-draft opening. By this means the furnace is prevented from smoking, a quick reduction of the garbage is accomplished in a most Veconomical manner and by the employment of the two grates, when desired, the reduction ing intermediatelyvv disposed stoking openi ings Vis that of avoiding the necessity of opening the grate doors and further that of permitting the operator to maintain the proper condition on both grates through the single opening. By having the escape or outlet flue substantially on the plane of the floor the advantages heretofore stated are acquired and the fire and burning gases are brought into directV and intimate Contact with the garbage on the floor. In 'actual practice it has been found that a minimum amount of coal and other fuelv is necessary in this furnace, in fact it is only necessary to use a small amount of fuel to start the furnace and the dried material is employed Having thus described this invention, what is claimed and desired to be secured by Letters Patent is:
l. An incinerating furnacel having a ina'-v terial-receiving impervious bottom part, a pair of grates located at the front end of the furnace at opposite corners thereof, the bottom part having a forward portion eX- tending between the grates, the furnace beingprovided with a stoke opening atv the front-thereof, centrally disposed between the grates adjacent said forward portionof the bottom for stolring both grates, the furnace also having a liue opening, and a YVfilling opening for discharging the garbage onto the bottom part in line Vwith the-Stoke open- An incinerating furnace having a material-receiving impervious bottom part, a down draft flue opening into the lfurnace adjacent the plane of the bottompart centrally of the sidesV ofA the furnace at the rear end thereof, a pair of grates located at the f rOllt end of the'furnace at oppositel coriis ners thereof, the grates extending substanour signatures in the presence of two wt- 10 ta-Hy in the horizontal plane of the bottom nesses. part7 the furnace having a Stoke opening between the pair of grates for stokng both grates, and a lng opening for distributing garbagesubstantially centrall7 of the bottom part, and an adjustable damper for Vtnesses: governing the down draft Hue.
