llpbu'pivotal sujpports there are banks of tubes as A, Band (I, with the nozzles of said pipe are'of a form to be projected beyond the edge of the pipe protecting battle to efi'ectually cleanse the upper portion of thejboiler tubeslas well as the connecting tubes between thexdrums at'the top of the boiler. V 1

In boilers of the type referred, to, the same are constructed with an inclined battle 10' extending transversely of the boile'r,di

rectly above or tothe rear of thebank of tubes A sothat the heat from the furnace F will be required topass up the bankA be-ti fore reaching banks Bv andC. This inclined bafile is generally provided near itsupper end with an ,upwardly-projecting ledge or guard 11 extending throughout the length of the baflle and projecting transverselyinto the space between the banks A and B. In this invention, I utilize this provided battle and its ledgeto shield the fluid distributing pipe and its nozzles from the heat of the furnacewhen tlxeyiare not I in use; To this end, l c' transversely of the boiler, near the upperl end of thcf baflle 101a fluid distributing pipe 12 suit-1 ably mounted and adaptedfor rotation wherebythe nozzles carried thereby may be projected over the upper edge of the battle,

and when not in use turned into position back of said bafile. This 'pipemay be ro tated inr-anysuitable manner, as by a sprocket wheel 14 on the outer end of the pipe, engaged by a chain 15, it being understood that adjacent the wheel 11 or other .form.,- of operating dQYlCB is a swivel. or

packed joint, such for instance, as shown in EichelbergerfPatent 705,912, July 29,1902, which permits of the distributing pipe being rotated without affecting the feed pipe (not shown), which, supplies 1 the distributing pipe with cleansing fluid,

"The distributing pipe ishere shownas received at its inner end in the boiler setting,

and intermediate its ends it" is supported by hangers 16 shaped at oneend to hook over the upper end of the bafiie" 10 and curved outwardly and upwardly at their lower ends to form seats or saddles 17 in which the pipe 12 is received. That strain maybe relieved from the upper end of the baifle, I

, also employ supporting brackets for the distributing pipe (see Fig. 6) consisting of a supporting rod or stem 18 socketedat its lower end in a base plate 19 that rests on I located, as to be protected fl'OIll' the directheatof the furnace chamber, and

the ledge 11, the rod or stem 18 at its upper end haying a sleeve-tor equivalent carrier'20 for the pipe 12. Both of these pipe supports may be used as here shown, or either of them, or any equivalentsupport, as I do not limit myself to any specific manner of supportingthepipe.

i To effect a desired projection of the cleansing fluid from the distributing pipe '12-, a nozzle isemployed which can be projected beyond the upper end of the baffle.

.The pipe is provided with as many of these nozzles as may be desired, and each consists of an elongated hollow stem or pipesection 21 connected at itsinner end to the pipe 12, and of a length to extend hey 0nd the. baflle 10, the outer end of the stem being curved back so that the discharge end of the noz= zle is on a plane parallel to the body or straight portion of the stem. Onto thisdischarge end of thestem, I preferably secure a nozzlemember 22 here shownas'provided I with a pluralityof discharge ports, one discharging straight in line with the discharge of the stem and the other at an oblique angle thereto. While the nozzle may consist only of the stem having the curved discharge end, it is desirable and preferable to use therewith the nozzle mcmber;having a plurality of discharge ports, as this construction provides for a wide sweep of the cleaning fluid during operation, the movement of the 110 zle members from the rest "position of the nozzles describing such an are as ,to pro ject the cleansing fluid onto the connecting pipes 23 between drums D, D","and "also onto the extreme upper portion of tubes in bank where they connect with drum D, and as the nozzles reach the full line-position shown. in Figs. 1 and 3," the cleaning fluid is projected both obliquely across the tubes and straight down along the tubes as shown in Fig,- 3'so as to most effectually cleanse the-tubes.

When not in use, the distributing pipe is rotated so as to turn the nozzles back behind the baffle 10 where they are fully protected 1 from the high degree of heat from the fire chamber that obtains in this portion of boiler of the type shown and described. Vh'en the hanger form of support 16 is em' f ployed. the saddle orseat '17 thereof is provided with a slot 17' that receives the stem of the nozzle and acts as a guide for the curvedends of the nozzles between the tubes of the boiler.

The location and aisai1ma0a0rt11e dispipe, rendering it possible "to apply parallel directed streams of cleaning fluid from a,

nozzle stems insuring the centering of the distributing pipe to portions of the tubes of a Stirling bo1ler it has heretofore been extremely diflicult to readily cleanse, and by employing multiple discharge orifices for the jets or nozzles, I am enabled to maintain the cleaning action during the entire move ment of the nozzles from their rest or normally inoperative position. The angle of the nozzles,"it will be understood,-will be in accordance with the distance of the end of the baffle from the steam drums. WVhen in the back or rest position, with the cleaning fluid turned on, the-straight-line discharge port of the nozzle member cleans ofi' the drum D and water tubes 23 and as the pipe is swung around the bottom of drum D and upper portions of the bank of tubes are cleansed, the cleansing action down along the tubes of bankA continuing as the nozzles reach the limit of their throw toward the bank A of tubes.
