Application filed August 14. 1908. Serial No. 448.473.

- To all whom 'it may'coigcern:

Ile it known that we, Enwaiin F. Inicn. of Lancaster, county of Lancaster. and TBoMAs I". Bexxerr, of Philadelphia, county of Philadelphia. State of Pennsyl vania, citizens of the United States, have invented certain new and useful Improvements in Incinerating Plants, of which the followino' is a. specification.

The object of this invention is the construction of a garbage and refuse furnace in which all of the material received is eutirely consumed; in which all liquid received is evaporated, and to which there is no need of a sewer connection; in which the. noxious "ases are thoroughly consumed; and which icing of simple construction can be installed in communities Where an expensive plant would be prohibitive; and owing to its snnphcityis of great durability, and when --neeessary to be repaired will not entail greatI expense.

:The material to be consumed is first subjected to a drying process, and the extraction of the major portion of its liquids. then drop ed to the niain furnace where it is cxpose for consuming, andthe further extract-ion of all liquids and their precipitation to means frovided for their complete evaporation. uring the initiai drying i process the released gases and vapors are convcdycd to a. heated flue and there consume Any heavy sparks or ashes which it would be dangerous `to have pass ont of Fig. 2 is a transverse vertical section on line .c u: Fig. 1. 4 Fig. 3 is a onc-halt` front View. Fig. 4. is an enlarged sectional view showing the corrugated removable separator between the drying chamber and the inaiu furnace. F f. 5 is a section on line v v Fig. 4. Fig. (3

.fla is an enlarged sectional view of a portion of the bridge wall. Fig. 7 is au elevation view fof Fig. 6. Fig. 8 is an enlarged sectional view. of the hooded overflow pipes. Fig. 9

is an inverted plan of the hood for the overflow pipes. Fig. 10 is a section on line A Fig. l omitting ash pit Fig. 11 is a .section on line l l5 Fig. 2. i

The structure is incloscd in a back wall 1, side walls :2. one of which may be a party wall when a hatten.' of furnaces are constructed, a front Wall 3 for the initial fire box, and an upper front wall Ll. The structure includes a chamber as a receptacle for thc material to be consumed. and in which it is subjected toa dryingr and draining process, comprising a metal ic top part 5, with doors (i through which to dump the material into the hopper T, formed of brick at the top of the niain furnace 8 and supported by an arch 9. rl`he dryingr and draining chamber formed by parts 5. and 'i' is segregated from furnace 8 by an inclined removable separator lt), 'which is preferably a heavy metallic plate with corrugat-ions 11, carried on rollers 12 which run on tracks 13 let iu flush into the sides of the brick work. The separator l() is upwardly inclined toward the outer' sido. of the furnace, and its control for insertion and withdrawal is by attached racks l-l, operated by pinions 15 0n shaft 1G supported iu brackets 1T. Upon shaft4 16 there is a groovcd pulley 18 carrying an endless rope or chain 19 whereb the rack and pinion are operated. iVhee s 20 bear upon the top of the racks to keep the gear teeth in contact. The separator l0 is stopped, when ,in operative position so as to leave a space between its inner end 21 and the adjacent wall, for the flow of liquid. The separator l() being of metal becomes intensely heated,

andthe corrugations 11 not onlv greatly in.

crease thc heating surface, and stillen the plate, but form gutters to convey the liquid to space 21 and project it on to bricks 42, and projections Stof bricks 33, thereby greatly assisting in the drying out process.'

Adjacent the main furnace S, and in communication therewith through arch 2:7., is the arched top initial furnace 23 and upon its I,:rates 24 the initial coal fire is built, an ash pit 25 is under thc grates, and suitable doors 26, and 27 are provided for the it and tire box. At 2S an opening is provi ed through wall 4 for facilitating the inspeetion of the process of incineration. and through which the material may be loosened up for the better aacit of the tlanics from the` initial furnace ITK. suitable. door will cover the opening Q8 and give access thereto. The main furnace 8 is provided with a bridge wall :29 forming a downtake tlue 30 between walls l and 2t). The construction of this bridge wall is illustrated on an enlarged scale in Figs. 6, and where 3l are the apertures formed in diagonal rows by rectangular bricks 3E! forming the sides, and their top and bottom sides formed by the overlapping dellector bricks 33. Bricks 33 extend into main furnace S beyond bricks 32 with their inner ends 34 downwardly curved with a curve between bricks 3f! in apertures 31, top part. 35 and the under art 36 being upwardly curved, and exten mg between the adjacent'I bricks 3Q, thus, with curves 35 and 36 forming apertures 31 manner to direct, the flames from the pile of refuse lying upon the bars 39 with interstices 4G at the bottom ot' main furnace 8,

'downwardly into downtake flue 30.

Owinnr to the multiplicity of diagonally disposedj apertures 31, both across and vertically through bridge wall 29 it matters notl how high the refuse is piled against the bridge Wali 29, as there is sure to be a draft, downwardly tending, into the downtake tine 30. At the upper part of the bridge wall 29 there is a brick 4l which extends into main furnace 8 for a less distance than bricks 33, and it has an inwardly sloping top 42, which receives the liquid passing through space 21 and projects it in toward the center of main furnace 8 and through interstices 40 of bars 39 t0 the evaporating table 43 which extends across under the Whole bottom partof main furnace 8, and forms the top of the bottom ' lues 44, 45. The evaporating table 43 is provided .with multiple overflow' pipes 46 which extend somewhat above the' table and are covered with hoods 47 to prevent the passage of any solids, the hoods being removable for cleaning purposes. The overf How pipes are supported by flanges 48, shaped to afford slig t obstruction to cleanmg table 43 by Scrapers. Flue 3() has a cover 49, and a side wall 50 over the flue 45 leading to the stack or chimney and an arch 5i! through its wall into Hue 44. Flue 44 has a concave bottom 53 extending beyond division wall 54 which supports table 43 and forms the return flue 45 leading to the stack Hue 51, and the lue 45 also has a concave bottom 55. A pipe 56 leads from the upper part of part 5 to flue 30 for the conveyance of the fumes and gases released in the drying process.

As seen 1n Fig. 11, iue 5l from its connection t0 Hue 45 is inclined toward the stack 57 at its top part 58, and its bottom 59 is level, and therefrom rises a corbellated back 60, forming a receptacle for the deposit of any heavy or dangerous articles coming from the furnace, and a cleaning hole 6l facilitates their removal. The necessary cleaning holes are provided as are also the necessary furnace, ash pit and vother doors, together with the usual binders, stay rods and the other supports usual 1n such i structures, which are well known and need not. be described. Between 'rates 39 and table 43, through bridge wal 29 there are openings 62, to form a down draft through intcrsticrs 40 to table 43 when the refuse is nearly burned out, for the purpose of consuming any greasy mass which may lodge on the table.

In the operation of incineration there is tirst a white heat produced in the initial furnace i223, which has an arched top to deflect the flames downwardly into furnace 8, this thoroughly heats main furnace 8, anl separator 10, then doors 6 are opened and the refuse is dumped into hopper 7 and onto .separator l0, when the released liquids How down in the gutters of the separator, through spacel. ou to sloping top 42 and drip on bricks at. 35 and are precipitated through iuterstices 40 to table 43, and the noxious gases and vapors removed through pipe 56 to flue 30. The refuse in hopper 7 having now been dried, sufficiently, and relieved of its liquids, the separator 10 is run back and the mass dumped into main furnace 8 upon bars 39, the mass naturally covering the bals and diminishingr in quantity'as it reaches upward against bridge wall 29. The llames from the initial furnace attack the mass, and, owing t0 the multitudinous apertures 31 the whole mass is reduced to a dry state which renders it fit. to be drawn into initial furnace 23 by rakes introduced through door 28, where it is utilized as fuel, by the addition of a. small amount of coal, to consume the following mass tojgbe consumed; this completely clestroy'srmferything received, and at a much'decrcased expense thanirf coal had l to be used exclusively. Aperturas 31 owing to the projections 34 covering their' entrance, and their curved tops 35 and bottoms 36 direct the hotl flames and air downward and toward the inner side of wall 1 which becomes veryhot and readily consumes all that passes thrm'rgh pipe 56, and downwardly therefrom to arch 52, through ues 44, and 45 on its way to the stack and thoroughly heats thc underside of table 43, meantime the burning mass in main furnace S heats the top of table 43, so that any liquids passing through intcrstices 40 on to the table arc evaporated.

To still further guard againstnon-eva oration of an excess of liquids passing to ta le 43 an overtiow is prcvided through pi es 46 to concave floor 53, from which if ll to overflowing the excess will pass to the lowex concave floor 55 of tine 45, and in these concave ioors the liquid is again exposed to the heated air and gases on their way to the stack. By means of openings 62, any fatty adhering sul-stances lodging on table 48 4.rc consumei'l, hy the liames from the inicrs't-iccd lioitom l() tlctlectcd to the taille by the. draft. through openings U2 to the downtala: ilu." l'ln' utilization of refuse with a small prifpor ion ot' coal, in the initial or primat-jt' l'ui nace insults' in ffrcat economy. 'lfhc complete evaporation nl all liquids saves the construction of counerting sewers, and the burning of the noxious' gases and fatty sul)- stances lrenders this plant void of objections in any locality.
