Abstract:  
The metal surface treating apparatus comprises a tubular lance, which is supported for rectilinear movement and connected to receive pressurized fluid and solid particles and discharge the same from one end thereof, and a deflector mounted adjacent to the discharge end of the lance and for rotation about the lance to direct the discharging stream of fluid and particles. The deflector is constructed and arranged to coact with the lance, upon rectilinear movement of the lance relative to the deflector, to automatically alter the direction of the stream of fluid and particles between one extreme position where the stream discharges in a direction substantially normal to the longitudinal axis of the lance and another extreme position in which the stream is directed coincident with the longitudinal axis of the lance.
