ABSTRACT:
A sandblast apparatus includes a telescopically nested tubular abrasive induction probe operable as a vacuum conveyor for inducting an abrasive material into a discharge apparatus. The discharge apparatus is supplied with a source of water under pressure which enters the discharge apparatus as a stream and admixes with the abrasive material in a diverging chamber. The discharge device, formed of lightweight aluminum material has an air control to afford remote control of abrasive feed and to form a protective air shield for the abrasive stream. After admixture, the stream is discharged through a converging nozzle to a point of utilization.
