ABSTRACT:
A universal abrasive cleaning apparatus comprising a plurality of arms which are rotatably connected in series with one another is provided. A plurality of nozzles are connected to the distal end of the series of arms by means of a nozzle support. Conduit apparatus interconnecting the nozzles to the source of abrasive and fluid are disposed within the interior of each arm thereby protecting the conduits from damage during manipulation of the arms. The proximal end of the series of arms is connected to a drum rotatably disposed within a housing. The drum is powered by a motor. A brake mechanism is connected to the housing for braking the drum during operation of the motor. An actuator is connected to each of the arms for rotating the arms about their respective axis of rotation. The actuator is controlled manually or by a microcomputer. The microcomputer receives rotational position information from sensors and directs the stream of abrasive and fluid emitted from the nozzles to trace a particular geometric pattern thereby cleaning an area of the work surface. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
