ABSTRACT:
A device for etching glass. An electric motor rotates an impellor enclosed within a housing into which abrasive particulate material is drawn by means of an inclined tube. The impellor, impellor housing and inclined tube are located within a compartment partially filled with abrasive particulate material. The blades of the impellor are arranged to provide a pulsating pressure. A flexible grommet defines a passage aligned with the housing outlet with the grommet conformingly and sealingly engaging the surface to be etched.
