One of the primaryobjects of this invention is to provide means; whereby cleaning fluid will be supplied to only a limited number of the discharge openings in said blower element at any p one timeso that the cleaning fluid will be discharged in .the form of one cr -more powerful 'jets.1. a g

The invention further contemplates the provisioii'of ,means fordischarging cleaning fluid into the blower element at any one-of a plurality of points and the provision of means'for'vary ing-the point of discharge of cleaning fiuidinto the blower element to vary the location of the jet of cleaning fiuid'discharged'froni the blower element." I r I Other objects and advantages of thisinvention,'together witnthe numerous novel details of construction thereof, will become more apparent as the following description proceeds, particularlyIwhen reference is had to the accompanying drawings, wherein: V -Figure 1 is aserni-diagrammatic sectional View through a boiler cleaner constructed inf'accordshowing the same in position in a boiler;

For the'sake of convenience the invention has V been described as being incorporated in a boiler cleane'rfor cleaning'part's of a boiler orthe like. It will be apparent, however, that the inventive principles disclosed might be'incorporatedin a cleaning device for cleaning any similar type of construction, and it is therefore to be understood that-theterm boiler wherever used in the speci- .paratusp 1 fication or claims is to be construed as meaning a'heat transfer apparatus or' fluidheater of anycharacter, whilethe term boiler cleaner is to be construed as meaning a cleaner for anysuch ap- While the invention has been described with considerable detail, it is to be understood that the description is for the purposes of illustration only and is not definitive of the limits of the inventive idea. The right is therefore reserved to make such changes in the details of construction and arrangement of parts as will fall within the purview of the attached claims.
