BOILER-BLUE. CLEANER.

No. season To all whom it may concern:

Be it known that I, ANDREAS GRoNvA D, a subj ect of the King of Norway, and resident of Milwaukee, in the county. of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Boiler- Flue Cleaners; and I do hereby declare that the following is a full, clear, and exact description thereof.

The object of my invention is to rovide a simple, economical, and effective evice for cleaning boiler-fiues, its construction and arrangement being such that by a system of steam-pipes in connection with a header, live-steam is admitted into a series of boilertubes, constituting a division of the whole, whereby the series of boiler-tubes are. cleaned or blown out, independent of the remaining.boilertubes, which tubes are similarly divided into series and connected to the sys tem of steam-pipes but independent of each other.

The invention therefore consists in various details of construction and combination of parts as hereinafter. fully set forth with reference to the acoom anying drawings and subsc uently claimed n the drawings: Figure 1 represents a sec tional front elevation of a steam-boiler ha"- ing attached thereto a flue-cleaner embodyl 1g the features of my invention, and Fig.2, a detail longitudinal section of the same, as indicated by line 2-2 of Fig. 1.

" Referring by numeral to the drawings, 1

indicates a StCEtHln-bOilQl' supported in the masonry walls 2, the boiler being provided with the usual lines 3 at suitably spaced intervals. Directly outside of one of the walls 2 is a vertically disposed valve-controlled steam-supply pipe or header 4, which header is preferdome not shown. Connected to the lower end of the header, b' a branch-pipe 4, is a horizontally disposer lead-pipe 5, which pipe extends across the front of the boiler-head just above the top row of flues and is 1provided with a cap at its opposite end, t iere being intermediate plugs .6 fitted into the pipe whereby separate divisions are obtained therein. Each division of the lead-pipe 5 is provided with a series of dep'endingtubes 7,

closed at their lower ends and having series of in number to the boiler-fines, which uesare directly opposite the depending tubes.

As shown in the drawings, the lead-pipe is separated into three divisions a, b, 0, re-

spectively by the plugs, the first division (1.

each branch-pipe having fitted therein a' valve 11, which valve together with the valye 8 serves to admit live-steam to division's'a,

'b, c, of the pipe 5, independent of each other.

From the foregoing description it will be readily understood that by opening any one of the valves, steam will be admitted into the corresponding division of the lead-pipe 5, and through its depending tubes to one series of boiler-Hues, after thoroughly blowing out the same the valve is closed, the o eration being repeated in the next series of ues, and so on until the entire boiler has been cleaned. Thus by simply operating a valve, the steam is admitted in any one of the series independently, it being understood that any number of series may be employed by interposing a greater or less number of plugs in the lead-pipe and providing a corresponding number of branches in connection with the header.

I claim:

1. A boiler-flue cleaner comprising a vertically disposed header, a horizontal leadpipe extending forward of-the boiler-head, plugs fitted in the lead-pipe, whereby sepaperforations alined with and corres ondmg rate divisionsare formed therein, serles of perforated depending tubes extending from said lead-pipe, branch-pipes connecting the divisions of'the aforesaid lead-pipe with the header, and an independent controllingvalve for each branch-pipe interposed be separate divisions are formed therein, 86-,

riesof perforated depending tubes extending from said leadipe, branch-pipes connecting the county of Milwaukee and State of Wiseon the divisions of the aforesaid lead-pipe with sin in the presence of two witnesses.

the header and an independent eontrolling- Y valve for each branch-pipe interposed be- ABDREAS GRONVALD 5 tween the header and branch-pipes. 'VVitnesses:

' In testimony that I claim the foregoing 1 GE(). W. YOUNG,

have hereunto set my hand at Milwaukee, in JOSEPH J. ZIMMERMANN'.
