INGILl'ERATING-FURNACE.

l Specification of'Letters Patent.

Patented April 21, 1968:

Application filed November 21, 1906. Serial No. 344,402.

To all whom it may concern." i ,Be it known that I, JOHN Ross, of the city and county of Philadelphia, State of Pennsylvania, have invented an 1111 rovement in incinerating-Furnaces, of whic the followmg is a specification.

My invention has reference to incineratin rated character, combined wit a lateral incinerating chamber having a perforated floor in rovided with flues for the ame and products of comassage of the and above and through ustion beneath said floor.

My invention further consists in astructure of flues by which the products of combustion from the furnace grate shall be di- .vided,- part passing under the ,incinerating v arch and incinerating floor and-"again be united abovesaid archand floor before pass ing to the chimney. p

My invention also vco prehends other features, of construction which, together with those above specified, will be better understood by which:

Figure 1 is a longitudinal sectional elevationof an incinerating furnace embodying .my invention; Fig. 2 is a sectional plan view of the same on line 2.2; Fig.- 3 is a transverse sectionof the same on line 3-3; Fig. 4 is a perspective view of a portion of one of the narrow arches of the incinerating arch and floor; Fig.5 is a plan view illustrating a modimodification.

fied form of my invention; and 6 is a A is the. furnace grate and B its bridgewall. C is a flue below the incinerating arch D and iskept at ahightem perature by the roducts of combustion from the furnace. he rodnets of combustion rise through end ue G and-thence ass backward over the incinerating arch l and-through -the incinerating chamberI-I to the flue H communicating WiththechimneyJ.

The incineratingarch is. preferably comreference to the drawings in.

'arches E an osed of open work so asto permittheflame om flue to pass upwardto the underside of the garbage. onthe arch. and also to on;

able the ashes from the incinerated matter to pass downward into the flue C from which they may be removed through. the side doorsO.

The incinerating arch D consistsofa series of narrow arches E-preferably of single. bricks properly" shaped and racked. up in arch shape with a small quantity of fire clay.

as a binder to compensate for uneven faces of l the brick.- I also prefer that these arch bricks shall have on one side protuberances S and on the opposite side depressions S as shown in Fig'. 4, so that the parts. S on one brick fit into the recesses S on the adjacent brick thereby making the arch very strong and insured against having1 its bricks displaced. These narrow arc es E .are preferably about nine innumber leaving seven.

transverse slotted portions or flues F opening u ward throu h the arch and connecting c amber H wit flue C. The end of the arc is provided with a bridge wall D to revent theg arbag'e passing over the end of t e arch. I isan inclined wall which extends obliquely upward from the forward end of the arch arid connects with the flue or throat H leadin to the chimney. The top of the chamber is arched so as to impart more or less reverberatory action and is furnished with a man hole P ofany suitable character.

is located to one side of the incinerating arch D. This chamber is provided with a'series of narrow arallel arches E constitutin forated oor. L, said arches being of t e same general character as the arches E and sepa; rated by open spaces. F. Below this perfoe rated arched floor L is a flueC, Whichcoma per;

municates at one end with the flueC 'adja-I cent to the fire bridge wall B by meansofthe flue I, and at the other" end with the charm. ber K above the floor, by flueG. The lines C and C are separated by a w C which-suigorts the ad acent ends of the but said fines are in commu 'nication at the end nearest the grate.A and preferably also at the distant end adjacent to the fluesG and G. If desired the said wall C may be continued to revent union of the gases, before passing t ough said fl'uesG q and G..' 4 r The floor L is provided with a bridge. wall 'L corresponding to the bridge 1? to-prevent 10 upon the (garbage from fa through the ening he chamber is provided wit an archedroof which is s rung in the direction of the length of the chamberI-I and forms therewith a groined arch structure. roof of the chamber'K is provided with a V garbage receiving door R of any suitable construction, that shown consisting of a' circular cast iron frame flanged; at the bottom and which rests a circular-lid or valve. The ably Iprovided with doors N opposite the fitrch and the chamber K so that rakes may e inserted fordistributin the garbage over 5 the arch. Likewise, the c amber K may be provided with side doors M to admit rakes or stokers for working the garbage on the arch L and if desired for transferring it to the arch D to complete its incineration.

0 The arches E and E are so constructed that they are very strong and being independent, may individually expand or contractto difierent de rees without affecting the adja-- cent arches. They may bequickly and cheaply repaired and the interlocking. construction of the bricks renders accuracy in building and stabilityin'use'. It also obviates the necessity of relying upon cement between the bricks to hold them in lace.

By making the spaces F and between the individual arches E and E continuous across the 'incinerating arches D and L there is more s face for action of the heat frombelow, less ear of clogging by the garbage and fuller opportunity for cleaning in caseofstoppagethan where the apertures are small in area. slots, a through 40 ertures.

The operationofmy. im roved furnace is as follows: The-productso combustion pass through flues C and C under the .incineratin arches D and L-thereby heating them; sai.

ea roducts then pass upwardithrough flues G 4 f and travel back above'the archesl) and L poker or rake may be inserted t in contact with the garbage upon the arches; the roducts then-pass'into flue H and escape y chimney J. The arbage is dum ed u on the arches D and the oorsand-R respectivelyand is then s read overthe arches. The under part of t e arbage is burned bycontact with theim P 8 is can escent arches and-by the flame upward through the spaces F and F, an the upper portions of the garbage are by the hot gases and reverberato .actionof the ,roof of the furnace. The as? lowed to pass down through the ap F in the arches to the fines-C Cbe ow. flame passing through these flues C, C, being very intense, any unconsumed garbage which ma pass down-through the apertures F F will be quickly consumed.

The wall C is not actuall required except as a support for the archgs l) and L and it is adjacent ends of these arches will suggest themselves to the engineer erecting the furnace, should he desire to dispense with said wall, Fi 6 being an example.

- It be observed that my-improved furnace has an inciner'ating portion or directly receiving the garba e greatly wider than the flue supplying thetion, this being to secure a large area for the free flow of the heatin whenlsaturated'with the vapors an ases g The ingases emanating from the garbage.

augmented by the burnin ofthe garbage) the reverberatory action 0 the arched roofs so increase the heat that the intensity of temperature above the archesD and L is mamtained at a maximum. If desired, an additional chamber K may "be arranged 'u' on the opposite side of the arch D, and th'is'is indicated at K m Fig. 5. Thiswould still further increase the area of the incineratin part of the furnace and may be rendered e ective b "care in supplymg adequate products of co bustion'from the furnace grate A. 1 have shown my I which I'have preferred to construct it for commercial use, and while I prefer thesame in the form. shown, I do not confine myself to the details, thereof as they may be modified without departing from the spirlt of my m- .vention. I Having now. described my invention, what I claim as new and desire to secure by Letters Patent,is:-" In an incinerating furnace, the combnation of a ate,"a lower flue leading-therefrom throug which the flame passes, an 1ncinerating arch having openings through it arranged abovetthe, lower flue, an mcmeratingcha'mber'immediatel above the mcmerating-arch and connecte with the lower flue at its end most distant from the grate, a chimney flue leading from the incineratmg chamber to'the chimney, a lateral incineratin'g chamber opening laterally from the mcineratin chamber above the incinerat ng arch an provided with an I incineratlng arched floor having openings through it, flues for causing hotgases' to pass under and then over the arched floor of the lateral. cham- .ber, and means for charging the furnace with garbalglf.
