ABSTRACT:
A portable system (10) for abrading the floor of a bathtub (26) to render it slip resistant. The system contains a portable power unit (12) containing an air compressor providing compressed air to abrading unit (14) via compressed air hose (20) and provides a source of electrical power to an abrading unit (14) via a power cable (18). The abrading unit (14) is adapted to direct a high velocity stream of abrasive particles against the floor of a bathtub through perforations in a particle impervious template (24). The unit (14) which is adapted to travel in the forward direction (indicated by the arrow), has a carriage movable in a direction lateral to the direction of forward travel. An abrading head (38) is supported by and reciprocally movable with a carriage to apply the particle stream in a direction lateral to the direction of forward travel and normal to the bathtub surface. A vacuum unit (16) is connected to a filter-hopper (40) mounted on top of the abrading unit for exhausting spent abrasive particles, filtering them and recycling them for further use. A control mechanism is provided for selectively advancing the unit in a forward direction or causing the abrading head to reciprocally traverse the unit in response to the location of perforations in the template.
