Abstract
A surface treating adapter device for use in combination with a recirculating abrading device includes an adapter housing affording a hollow cup-shaped chamber, an aperture in the housing to receive the discharge nozzle of an abrasive gun, an exhaust outlet including means for detachably engaging a low pressure line from the abrading device, interchangeable hollow working tool members, and tubular connecting members releasably and adjustably joining the adapter housing and a selected one of the tool members. The tool members which contact the surface to be abraded are each of varying configuration for accommodating surfaces of varying contour and for making a sealing engagement therewith. The abrading operation is performed within the confines of the tool member being used. Abrasive is introduced through the housing aperture and impinges upon the surface area enclosed by the tool member. The scale and debris, including the spent abrasive, are then drawn through the chamber of the housing and through the exhaust outlet to the abrading device, and there separated.
