In this particular locality it is necessary to .layfuphtug boats .fromutime :to time for removing iniudiithereirom, which entails considerable lossoftimeand money. To oven come this difiioulty a boiler cleaning device COlDPFlSlIlgil cond-mtfl disposed on ithe bottom 3 of the bo1'ler,.,and through which con- (lltiti-blle mud intheibottom of the boiler is forced when the blow off valve scarried by theblowoffpipe "5 is :openedi The boiler conduit 2 isatoraned from-a plurality of: sections2eseini-circularin transverse c-ress sec: tion, said sections being provided with notchesb vin their edges, which notches when the (IQHCiuiit-BdlSiit whole -disposed on the bottom :orf @the boiler tor-1n apertures through which the sediment and inud'in the bottom of the boiler will be forced by the pressure within the boiler and forced through said conduit to the chamber 7 of the blow off pipe hood 8, and, thence through the blow off pipe 5 to any suitable The conduit sections 2* overlap each other and are detachably connected together by means of bolts 10, said bolts allowing thesections to be easily and quickly assembled or disassembled as de sired. The blow off pipe hood 8 is provided with "extensions 8, to which extensions the adjacent conduit sections 2*" and 2" may be attached, sections 2 being substantially the with the exception that they are provided with closed ends 2, which ends may be provided with notches 6 through which mud and sediment may be forced by the pressure within the boiler. A conduit section 2 simi lar in construction to the conduit section 2", is provided, which section may be utilized at the opposite end of the conduit from the end carrying the hood 8.

Referring to Figure 6 in which a modified form of blow ofl hood 11 is provided, it will be seen that said hood is substantially the same as the hood 8 shown in Figures 1 and 2 with the exception that one of the extensions 8 is eliminated, thereby obviating the use of the conduit section 2*. The hood 11 is particularly adapted for use in connection with boilers where the intake end of the blow off pipe 5 is located close to one of the end walls of the boiler, and in a position where the section 2 could not be used It will be seen that blow off pipe either of the hoods 8 and 11 will entirely house intake end of the blow off pipe 5 and that sediment forced through the conduit would enter said housing and pass into the blow off pipe.

Pivotally mounted in an aperture 12 in the hood 8 is a vertically disposed shaft 13, which shaft extends downwardly and terminates in a spider 14, disposed within the upper end 15 of the blow off pipe, said spider and shaft forming means whereby the hood 8 will be maintained in registration with the upper end 15 of the blow off pipe and also forming means whereby the conduit 2 may move in a horizontal plane incident to movement of the vessel thereby allowing said conduit to dislodge the sediment or mud at the bottom of the boiler, and at the same time prevent solidification of said mud or sediment in the bottom of the boiler for the reason that the conduit 2 is constantly n1oving incident to rocking or pitching of the vessel or to its natural roll from an even keel.

Extending upwardly from each conduit section 2 is a vertically disposed pipe 16. The upper ends of the pipes 16 terminate in conically shaped skimming elements 17 having helically shaped passages 18 therein. The conically shaped skimming elements are disposed below the surface 19 of the water 20 within the boiler and form means whereby scum and foam which may form on top of the water will be conducted downwardly, thence through the conduit 2 and into the blow off pipe 5 when the blow off valve 4 is opened. It will be seen that the helically shaped passages 18 in the skimming elements 17 will set up a centripetal action in the water above the skimming elements, thereby increasing their skimming area. The lower ends of the vertically disposed pipes 16 are detachably connected to the conduit sections 2 at 21, thereby allowing the parts to be easily disassembled for shipping and storage purposes.

From the above it will be seenthat a sediment removing and'water skimming device is provided for boilers, which device is simple in construction and so constructed that the same may be applied to boilers without varying the construction thereof.

The invention having been set forth what is claimed as new and useful is The combination with a boiler, of a cleaning device therefor, said device comprising a horizontally disposed conduit disposed on the bottom of said boiler, said conduit being segmentally shaped in transverse cross section, the opposite edges of said conduit being notched, said conduit being formed from a plurality of sections, the adjacent ends of said sections overlapping'and being secured together, said boiler bottom being provided with a blow off pipe, a hood forming one section of said conduit and entirely housing theblow off pipe,-a vertically disposed pin extending through the hood, said pin having its lower end disposed within the blow off pipe and a plurality of ribs carried by the end of the pin within the blow off pipe.

In testimony whereof I have signed my name to this specification.
