ABSTRACT:
Self propelling jet nozzles especially suited for cleaning sewer pipes and the like are formed from a tubular body member and a nose cap by machining parallel inner and outer ledges or shoulders inboard from the leading end of the tubular member at a rearwardly inclined angle, drilling a ring of circumferentially spaced bores diverging outwardly from the inner to the outer ledges and tapered toward the outer ledge, securing wear resisting nozzle tubes in the bores in mated relation with the tapered portions thereof and welding the nose cap on the leading end of the tubular body. The trailing end of the body is threaded to receive a water conduit, the nozzle tubes in the bores discharge rearwardly and outwardly around the trailing end of the body to propel the nozzle forwardly. The nose can be provided with one or more passageways discharging forwardly and these passagways can also be provided with wear resisting tubular nozzle inserts. The joining end of the tubular body and nose are tapered to provide a V groove with welding material filling the groove. The outer diameter portion of the tubular body rearwardly from the external ledge is machined to provide a conical neck extending rearwardly and radially outward from the radial inner end of the ledge. This neck conforms with the inclination of the bores so that the jet streams emerging from the nozzle tubes surround but do not impinge against the tubular body.
