new and useful Improvements iii Traveling- Grate Furnaces; and I do hereby 'declare that the following is a full, clear, and exact description thereof, reference being hadito the accompanying drawings, and to thelet- "ters, of reference marked thereon, which said grate conveying device.

-This invention relates to improvements in furnaces of that classembracing a traveling or chain; grate on which thefuel rests and by `which it is carried along -or through the Afurnacedurng the process of conibustioii,'and more especially'to-an.improved means for .keeping separate from the ashes -`discharged froni the rear 'ends'of the grate particles of unconsumed fuel which fall through the the ash-pit.
.The invention consistsin the matters here-i ina'fter described and pointed out in thefall to the bottom of the ash-pit. ,At the 'appended claims.
stood by reference to thev accom anying drawings, in which my invention is s own in connection with-a boiler-furnace. i

Said endless travelinv grate'A'is supported mounted in afraine B1 whichl isprovided with supporting wheels b1 b. Said wheels b1 b1 rest and travel 4uponhorizontal track rails C Cjwhichaielocated j at the level -of the furnacef'room-oor and extend into tl'iefurnace v chamber from front to roar 'androutwardly 'throughfthe front.
Y openingr of thefurnace, so as to ,permit the grade supporting frame and grate to be withdrawn from the furnacev when' desired. The
andfor removing such ashes, from grate vand its support areuarranged in the saine Imanner as heretofore common in boiler-furnaces.`
. D D indicate the side walls and D1 the bottom wallor floor of the ash-pit. Said boti toni wall or floory is located considerably below the level of the rails C C andof the furnace rooinfloor and is, in its-main part latv and horizontal -or approximately soz At its forward end, said ash-pit oor ter'mmatesat .a pit or depression D? located adjacent tof the forward end of the grate and referably provided with a vertical rear ,wa l dl and an iip' wardly and forwardly inclined frontl wall d1. Beneath the'track rails C C, and supporting the same, is a horizontal partition E separat-- at ,thelv rear of the furnace on open space.
through :which ashes and burned-out fuel discharged at the rear endof the grate may rear end of the partition is located a bridgewall E'l which'rises from: the artition and terminates near the level of the lbottoni of the su orting frame Bof the. grate.
F indicate two rods which eXtend-long-itul dinally of the furnace and are arranged parallel with each other and' parallel with and at a short distance above the ash-pit floor. Said rods are supported' orsu'spended by suspension membersv f f from the partition E above them. Saidl suspension members f f are flexibly connected with the rods and with the partition-seas to permit longitudinal niovement of the rrods l l As shown 1n the drawings, the suspension niembers'ff'consist ofl chains which are con- ;nected at their. u per ends with the transl bars c ee of said partition Connected With .the rodsF F, below the samepare a plurality-of transverse, vertically verse supporting 'arranged plates GG which are flex'ihlyconnected at. their upper edges with the said rods andarearranged at uniform distances apart along said rods, which latter rextend rearwardly ofthe reaniiiaigin of the parti- 'tion Eto pointsabovo the roar end of the ash-pit `floor;v Athe icaii-nost of the said plates l i I i 0f the plates and said. rods.
G being located-near the rear end of said this construction affording a fieXible or hinged connection between the'upper edges y In the construction illustrated, moreover, the said plates are held from swinging rearwardly from the vertical position thereof by means of diagonally arranged flexible, connecting members or d20 chains g1 g1, which are attached at their llower ends to the plates near the bottom edges thereof, extend upwardlyand forwardly from their points of attachment to the plates and arevsecured attheir upper l ends to the said'rods atpoints forward of the pla tes.

4means of rods, one of which is shown in Fig.
1. at H1.
. The rods F F, being suspended by suspension members ff, as described, .the effect' of .40 giving endwise movement to said rods by the eccentrics, as described, 1s to impart tov 4the rods an oscillatory or swinging motion in curved paths, the rods rising' and falling as they are moved backward and forward froml the central. or depressed position thereof.
The plates G G are correspondingly moved or swung; rising and falling -relatively to the floor of the ashspit as they are moved backs wardlyT and forwardly over the saine. The
said platesare supported at such elevation that when the rods F F are depressed and the plates .hang lfreely from -the rods, they willstand approximately in a vertical position with-their lower edges in contact with the ash-pit floor, or closely adjacent thereto. Preferably they come in actual contact with or rest upon the floor when the rods are in their depressed or central position. As a result of the hinged connection of the 69 said plates G G with therods F F, and the employment -of means limiting the backward swing of the said plates from the vertical'position thereof, said plates, in the backward movement of' the said rods, will swing forwardly or rise and pass over any ashes resting onJ the floorof the ash-pit, but will resume their upright positions andscrape or carry forward along the floor the ashes engaged by the lower edges thereof in the lower movement of said rods. i The` backward and forward movement of the rods and plates will therefore have the edect of dragging or scraping forwardall of the .ashes on the ash-pit floor, and this result will follow whether the supporting rods F F be hung or supported so as to rise and fall in their endwise movement or not. Itis preferred, however, to suspend 4the rods in the manner illustrated, the effect of the rising and falling movement thereby plates carried thereby move in curved paths tions; the lower edges of said plates being lifted vabove the .ashes when they reach the 'rearwardvend of their stroke and also at the termination of their forward stroke. result of the movement f the plates in curved paths,l therefore,`is that the mass of ashes on the ash-pit Hoor will be advanced in the form ofv lseparate transverse piles or ridges,
forwardat each forward movement of said plates.- The employment of swinging susension members-for the rods, as illustrated, as the'advantag'e of providingia very simple '1"mea`ns. for movably supporting. the rods, which is cheap in construction and not liable to get" out'of repair, while at the saine timev .affording an eHective action inthe plates in advancingfthe ashes along the aslbpit floor.
are delivered fromthe forward end o' the latter into the pit or 4de ression D?.l
`I have shown in-t re accom anying tending along the front ofthe lfurnace adj a- `cent to the pit D2, and adapted for the passage therethrough of an ash-receiving car J, the top of which is located about at the level cated a plate d2 which forms acontinu'ation of the top surface of said wall, and overhangs the car J. By this construction, ashes deposited in the pit D2 may be easily scraped therefrom upwardly alongv the 4wall d1 and intothe car J, by which they may be re-l moved to a desired place of deposit. l
The rods F F constitute in effect a supporting frame or member for sustaining and giving bodily movement-to the scraper plates, inasmuch as said rods have equal sin'iultaneous movement, and although shown inthe drawings as separate f rom each other, oper- Vate in the same manner as though they were rigidly connected with each other or constituted part of a single frame.
