  • Patent number: 4212138
    Abstract: Portable sand blast apparatus for cleaning a surface at a confined location wherein the apparatus attaches to a conventional sand blasting nozzle and includes a flexible filter shroud having an open end terminating in a resilient sealing ring. The shroud confines the sand blast particles and functions as a filter bag to permit the escape of air while the flexible surface seal prevents escape of the particles adjacent the surface being treated. A handle is mounted at the shroud open end, and a transparent window may be incorporated into the shroud for visibility purposes.
