ABSTRACT:
A manually portable casing equipped with suitable handle means has an outer end opening and a sandblasting hood mounted in the casing has a corresponding outer end opening which fits into the outer end opening of the casing. A rotary blaster nozzle inside the hood is supplied with a stream of air entraining grit particles. A rim of the hood has a continuous resilient seal to contact a worksurface that is to be processed thereby to cut off the hood both from the atmosphere and the interior of the casing. The hood and its seal are shaped to cooperate with a particular worksurface configuration which may be concave, convex, angular, etc. Different hoods are used interchangeably to fit different worksurface configurations. A suction pump connected to the hood maintains a relatively high vacuum therein and thus tends to compress the seal against the worksurface with force which, if unopposed, would immobilize the sandblaster, but a plurality of thrust members around the hood make rolling contact with the worksurface and thus divert a sufficient portion of the force to relieve the seal sufficiently to make the hood readily manually movable along the worksurface.
