Abstract:  
Apparatus for peening small inaccessible areas such as one-half inch in diameter or smaller holes with microscopic glass bead media by placing the media in a pressurized container having substantially the same uniform pressure as is applied to the needle nozzle utilized with a peening operation, the beads being supplied by gravity to the nozzle through a pressure regulated valve which is included in a vertical channel leading directly from the container to the conduit which terminates in the nozzle.
