ABSTRACT:
A portable sandblasting apparatus for continuously treating horizontal surfaces along a path of adjustable width. The apparatus is mounted on a movable platform which is drawn by a motor vehicle or self-propelled along the desired path. The apparatus has sandblast nozzles which reciprocate from side to side with respect to the direction of motion as the apparatus advances so as to provide treatment of a pre-set width of surface. By adjusting the amplitude of reciprocation, positioning the nozzles for continuous coverage and by varying the number of nozzles functioning, the width of surface to be treated may be varied greatly and readily adjusted.
