Application led Hay 20: 1909. Serial No. 497,281.

To all whom 'it may con'eci'ni:

v Be it known that I, JOHN J. HANLON, a citizen of the United States, residing at Troy. county of Rensselaer, and State otl New York, ha've invented certain new and useful Improvements in Soot-Ejoctors for rater-Tube Boilers` of which the following is a specification.

The invention relates to such improvements and consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompauying drawings, and the reference characters marked thereon. which form a part of this specification. Similar characters refer to similar parts in the ,severaPtigures therein.

Figure 1 of the drawings is a vertical lon- Jitudinal section of a water-tube boiler provided with my novel :soot-rejectingr mechanism. Fig. 2 is a horizontal section of the saine taken on the broken line 2-2 in Fig. 1. Fig. El is a horizontal section of one of the soot-cjecting nozzles detached.

The principal object of my invention is to effectively remove from time to time accumulations of soot, ashes, &c., from a water-tutu! boiler without injury to the brick-work incasing the boiler.

Other objects will appear in connection with the Followingr description.

.teferring to the drawings herein thc invention is shown in preferred form, 1, represents the cylindrical body of the boiler, from which depend the front, water-le; r, 2, and roar water-leg` Il, said water-legs being connected together by a series of water-tubes, 4, in tho usual manner. Above the uppermost row of tubes, 4, is the usual baille-plate, 5. formed by tiles of tiro-brick extendingl from the rear water-leg to within a short distance of the front water-leg, leaving thcrcat an opening. t3, from tbc space coutainiug thc w"itcr-tHbes up into thc space. T between the baille-plate, 5, cylindrical body, 1, and the setting of the boiler,- which space 'communicates with the stack 8. ln lik(l manner above the lam'ermost row of tubes is a baille-plate. il, extending from the front water-leg to within a short distance of thcY rear water-leg, leaving thcrcat an opening, 10, leadingr from thc comlmstion-chamber, 11, upward into the space between tbe two baille plates.

0u opposite sides of the boiler, adjacent tu tbc opening, 10, l mount in the boilersettinga pair of nozzles, l2, each in connection with a supply-pipe, 19, leadin from a suitable supply or' steam or air un er pressure, which source of supply may be the body, 1, of the boiler. Each of the nozzles, 1:2, is provided with a lurality of inwardly and forwardly extending nipples, 13, the nipples of said two nozzles being 'directed eonvergently forward toward a `common point just above the opening, 10, whereby the jets or steam or air ejected under 'pressure from said nipples are caused to impinge, those from one nozzle against those from the other, while causing, a forward currentJ of great velocity which not only drives before it toward the front end of the boiler soot accumulated upon the several tubes, but also causes a forced-np draft through the o cning, 10, adapted to force u )ward throng said openinfr accumulations o' soot. or ashes on the bri ge-wall, 14, or walls of the combustion-chamber I1. ln like manner I mount in the boiler-settin \,l on opposite sides of, and just above, the opening, 6, a similar pair of nozzles, 15, each connected with a supply-pipe, 16, lending from the boiler-body or other source of supply of steam or air under ressnre, each of said nozzles, 15, being rovided with a plu rality of forwardly an rearwardly extending nipples, 17, the nip les of said two nozzles, 15, being directed) convergenlly rearward just above the openinff, 6, whereby the jets of steam or air ejeter under pressure from said nipples, 17, are caused to impingc, those from one nozzle against those from the other, while causiiw a rearward current of great velocity which not only drives before it to Iard the, rear cud of the boiler soot accumulated upon the baille-plate, 5, body, l, ot' thc boiler, and walls of the lmiler-setting, but also greatly accelerates thc forced-up draft through the opening, wbcrcby the nozzles, tf, coiipcratc with thel nozzles, l2, to eject accuundationrI of soot and ashes from thc water-tubes. 'lbc members ot' each pair of oppositcly-locided nozzlc-outlels which converge toward a common point preferably occupy substantially the saine horizontal plane just above the draft-openy ing.- Hy having the oppositely located nipples directed convergently and obliquely,tbe nnpugemcnt. of thc jets from one nozzle upon thosel from the other oppositely located nozzle prevents the jets from striking the side walls of the boiler-setting at. u favorable angle, and with suiiicient force, to injure or wear away said'walls. The reinoxed soot and ashes are carried up the stack by the forced draft created by the combined action of the nozzles, 12 and 15.. A

By admitting to the Ynozzles steam or air under pressure for a period of a few minutes each day, the tubes and walls of the boiler can be kept' practically clean and free from accumulations of soot and ashes.

What I claim as new and desire to secure by Letters Patent isl. In a water-tube boilerQthe combination with the boiler-body; Watertubes; and boiler-setting; of a bathe-plate partly inclosing the tube-containing space and provided with a draft-opening; a pair of ejector nozzlesmounted in the setting on opposite sides of one of said draft-openings, said nozzles having nipples convergently inclined toward each other in the direction of the draft, and having; their outlets in substan-A tially the saine horizontal plane justl above said draft-opening.

2. In a Water-tube boiler, the combination with the boiler-body; watertubes; and

boiler-settingg of upper and lower baieplates partly inclosing the tube-containing space, said upper battle-plate being provided with a tirait-opening at its front end, and said lower baille-plate with a draft-opening at its rear end; a pair ot ejector nozzles mounted in the setting on opposite sides of, and just above, the draft-opening in the upper hama-plate, and having nippleseonvergentlj: and rearwardly luclined, with their outlets in substantially the same horizontal plane; and a pair of nozzles mounted in the setting on opposite side-2: of, and just above, said draft-opening in the lower initiieplate, and having nipples Courel-gently and forwardly inclined, with their outlets in substantially the saine horizontal plane.

3. In a water-tube boiler, the combination with the boiler-setting; of n pair of ejector nozzles mounted on opposite sides of ,the space inclosed by the setting, and having their outlets convergent toward eachother in the direction of 'the draft through' said space and toward a common point.

lin testimony whereof, 'have'hereunto set my hand this 14th day of .May, 1999.

JOHN J.. HANnoN.'
