Abstract Apparatus for use in inspecting ferromagnetic wall members. The apparatus comprises a telescopically extendable pole member having a carriage attached to the extendable end of the telescope. The carriage comprises a mounting frame attached to one of its ends to the extendable end of the telescope. A shaft extends through the mid portion of the mounting frame generally perpendicular to the telescope. Wheels consisting at least in part of permanent magnetic material are rotatably mounted on each end of the shaft. An ultrasonic transducer is attached to the other end of the mounting frame. An electric current carrying cable is electrically connected to the transducer and a waterline having an open end adjacent the end of the transducer is attached to the mounting frame.
Apparatus for non-destructive inspection of vertical ferromagnetic wall members comprising: A. a carriage, said carriage comprising 1. a mounting frame having one pair of arms extending upwardly and a second pair of arms extending downwardly, 2. a deep plate member fitted between the downwardly extending arms of the mounting frame and a shaft passing through said arms and said plate member, 3. a shaft passing through the upwardly extending arms of the mounting frame and a support member mounted on said shaft in rocking engagement with said shaft, 4. an ultrasonic transducer mounted on said support member, 5. a fender member mounted on the lower surface of said support member, 6. a shaft passing through said plate member and a wheel formed from strongly permanent magnetic material mounted on each end of said shaft, B. an electric current carrying cable in electric connection with said transducer, C. a waterline having an open end adjacent the face of the transducer, and D. a telescopic pole member supporting said carriage attached to the deep plate member and so aligned that it is perpendicular to the shaft on which the magnetic wheels are mounted.
