Patented July 13, 1909.

Application filed April 16, 1907. Serial No. 368,564.

To all 10710772. it rmay concern Be it known that l, OinnNn D. Oiwis, a citizen ot the United btates, residing in the city of New `York, borough of Manhattan, and State of New York, have invented a eertain new and useful StcanbBoilcr Furnace, of

which the following is a specification.

This invention is a steam boiler furnace, and it appertains more especially to that type of water tube boilers wherein inclined water tubes are cniployed in connection with ineans operating to direct the sinoke, gases and other products of combustion in :i circuitous path back and forth between and around thc aforesaid inclined Water tubes.

ln one type of furnace constructed in aecordance with this invention, a plurality ol" niantlcs `or arches lic over the. `tirate and within the grate-clnnnbor, said arches being` spaced relatively to one another' to produce an intermediate throat for the passage oll the. products ot' combustion, and means whereby a blast, or a plurality of blasts, ol steam and air, either singly or jointly, are projected across the aforesaid throat, whereby said blast or blasts are thrown into the ascending,` current ot the products oi' combustion l'or the impose of disintegrating the smoke, increasing the. combustionot the gases, and augmenting' the drat't and the heat.

Vlt is preferred to employ blast devices operatingr to `direct currents in intersecting paths and across thc aforesaid throat, and, further, to combine. steam and air prior to disehargjinpl the blast or blasts into the products ol2 coinlnistion. llurtherinore, it is preferred to provide means for scouring a circulation ot water from the boiler through the grate-chamber, for the two-told purpose of generating steani and for reduennfy the temperature of certain nietal parts enip oyed in the grate chamber for supporting;- the mantles or arches therein.

In the. accompanying drawings, l have illustrated one practical enibodiinent of the invention, but t ie Construction shown therein is to be understood as illustrativo only, and

not as deiining the limits ol the invention.

Figure l is a vertical section showing the present invention in connection with a Waterl tube boiler of that typo wherein Water tubes are employed in an inclined position relative to the (irate-chamber and the escape ilue or fines. `ig. 2 isan enlarged vertical section through the grate-chamber ot the water tubo boiler shown in Fig. l, the dotted lines illpstrating' the direction ol" thel blasts from a plurality of blast pipes, the plane ol the scetion being,r indicated by jthe dotted line 2-*2 ol Fig. Fig. 3 taken in the irregular plane indicated by dotted line 3 3 ot Fig. 2. Fig. 4 is a vertical cross section on the line llt-4 ot Fig. 2.

The water tube boiler shown in Figs. 1 to 4 inclusive, consists ot a grate-ehamber, A,the inclined water tribes, B, and the steam dome, C. lin the chamber, A, is a grate, (1 sup ported at one end by a bridge wall, D. Ex,- tendine upwardly rfrom this bridge wall is a partition, ll, which directs thd products of combustion upwardly through one. portion of the water tubes, B, over the rrate-elnimber. llxtendinfg downwardly l'roni the boiler, (l, is a baille, l"`, and 'from this baille. extends another partition, ll, whereb the products oi combustion are caused to ,pass downwardly between the partitions, lll ll", anld thence npwardly in rear ol` the partitions, l', to the outlet, e, which communicates with a stack or up take.

The generator thus tar described is oi tho l'aniiliar typo known in the arl. as a water tube boiler, and the several parts may be constructed and arranged in any usual or preierred way.

lVithin the grate-chamber, A, at a suitable height above the grate, o, therein, are inantlcs or arches, tl, (l. Said manlles or arches are su )ported partly by water circulating pipes, l, ll, and by brick work, l, l', in which brick work there. arey embedded the blast pipes, J, J.

rl`he mantle, (l, is supported at its front end on the wall, o, ot tho boiler setting, while the inner end ot said nianlle shown as resting' upon the blast pipe, J, and the brick work, l. The other mantle. (l, is supported at its rear edge on the bridge wall, l), while the l'ront edge oll said member rests on the. blast pipo, J, so as to be supported by the brick work, l/. The. two niantlcs, G, (l, are 'spaced at their adjacent edges so as to produce a throat, li, between them, through which throat the smoke, gases and other iroducts of combustion are adapted to pass in order to escape trom tbe grate-chainber, A, into the circulating ilues around the inclined water tubes, B. lt is preferred to arrange the mantlcs in approximately horizontal positions and so that they extend is a horizontal seotion nozzles, j, j

l may employ from side to side of the furnace. Flach mantle may be composed ot' any suitable or appropriate material and installed within the grate-chamber in a suitable way, but in one ractical form of the invention each mantle 1s composed of blocks or slabs ol fire roof material, such as lire clay, said blocks eing molded in a suitable shape and size, and,

baked or otherwise treated in a way to render it indestructible to the action oi heat.

a single water circulating ipe in connection with each brick work, l, l', but as shown in Figs. l and 2, it is preferred to employ said pipes, H, H', in pairs.J Said pipes, H, H', extend horizontally across the gratachamber so that the end portions of the pipes are embedded in the side walls, a2, of the furnace, sep Fig. 4. v The end portions of the pipes, H, l, Well the end portions of the pipes, H', H', are coupledor united by headers, a, h', which are, also, embedded in the side walls, each header being )rovided with a suitable removable closure, 1'. The two pairs of ipes, il, ll', are spaced at the respective si es oi the throat, K, and as said pipes are supported directly by the side walls of the furnace, they Jfurnish a convenient and secure means for supporting the brick work, l, l'. lt is evident that the brick work should be composed of lire'prooll material, and that said brick work may be `easily, quickly and accurately laid on the pairs of water circulating pipes, l-l, ll'. During the installation oi the brick work, the olast pipes, tl, J', are placed in position so as to be embedded in the brick work or incased thereby. The' tiles composing the inantles or arches, G, G', are adapted to be laid'or placed in position easily, quickly and accurately, ano the entire apparatus may be installed without the employment ol skilled labor. v. The water pipes, il, ll', may be connected in any suitableor approved manner with the inclined water tubes, B, or with other parts o1" .tlie water tube boiler. ln Figs. 3 and 4l have shown circulating pipes, L, L', connected to the respective headers, h, h', of the pipes, H, ll', and these circulating pipes, L, L', are adapted to be connected with the inclined water tubes, or with any other part of the boiler, for the purpose ol' securing the desired circulation of water through the pipes, lil, l-l', whereby said pipes are protected against the excessive heat of the urnace.

lt is preicrredv to employ two blast pipes, il, J', and to provide said pipes with series of respectively, as shown in Figs. and 3. The rear side of the brick work, l', orn that side Vnext/to the throat, K, is provided with aserios ol" opeiiings, t, which are inclined upwardly, and into these openings extend thc nozzles, j, of the blast pipe, il, whereby the nozzles are adapted to direct a `the nozzles of the pipe,

, tions one to ployment or 4directing a blast or blasts across sewers blast rearwardly and across the throat, K, said blast being in u wardly inclined paths. The front surface cip the brick work, l', or that surface next to the throat, K, is rovided with a series of openings, i', into w ich extend the nozzles, j', of the blast4 pipe, J', and these nozzles are inclined slightly in an upward and forward direction for the purpose of directing a blast across the throat, K, the direction of the blast from the nozzles of the pipe, J', being opposite to the blast from scription it will be apparent that the two blast pipes, J, J', are provided with` nozzles arranged to direct blasts in opposite directhe other, said blasts from the pipes intersecting one with the other. Furthermore, the nozzles, y', ot' the pi e, J, are not in the saine plane 'longitudineJ ly of the furnace chamber-as the nozzle, j', of the other blast pipe, J', but as will be noted by reference to Fig.`3, the nozzles of one blast pi e are in alternate relation to, or out of alinenient with, the nozzles of the other blast pipe, whereby the nozzles ot' the two blast ipes are stag ered. Furthermore, it is referred to emp oy nozzles which are of attened construction, in order that the blast issuing from the flattened or elongated nozzles may spread or diverge horizontally. The nozzles of the two blast pipes employed in my invention are arranged to direct the jets or 4streams of steam and air in such a way across the throat, l, as to break up or disintegrate the cloud ol' smoke which arises from the bed of fuel resting on the grate, c, and the result or this injection oi the blast is to intiniately combine steam and air with the products of combustion for the purpose of increasing the combustion oi the smoke and gases", whereby the intensity of heat is augmented b' the admixture ot oxygen with the gases an 'the thorough combustion 'of said gases is assured.

B reference to Fig. 2 of the drawings, it will oe observed that the water pipes, H, H', and the brick work, l, l', are in lanes below the ends ofthe mantles, G, G', w ich are supported by the front wall, o', and the bridge wall, D, respectively, and furthermore, that the adjacent ends of the mantles, G, Gr', arev J. From this de` iro below theother ends of said mantles, whereby the mantles may be said toconverge downwardly toward each other, The emthe mantles over the grate, and

s aced to produce the throat for the escapeof tue products of combustion, is an important feature of my invention, and the `employment oi one or a plurality of blast pipes for said throat `is another important feature. ln the prac- Atical operation ot the Afurnace, the smoke and arising from the bed ol' fuel on .the

grate circulatea in upward direction and strike against the nantles, but the blasts CTB across the throat draw the smoli, and gases downwardly and beneath the water pipes. ll, H, and thence upwardly through the throat, whereby the products ofv combustion are whipped7 orcaused to move with increased velocity around the inner edges of the-mani what l claim as new and desire to secure by Lettrs'Patent is:-
