Abstract
An articulated arm having first and second pairs of parallel spaced apart pivotable linkages associated with a tire casing holding fixture for moving an array of ultrasonic transmitting transducers to and from a location exterior to the tire casing and a location between the two sidewalls of the tire casing with the faces of the transducers being a predetermined spaced distance from the interior surface of the tread bearing portion of the casing. Only a single piston/cylinder type actuator linked to the arm is required to achieve the desired movement and positioning of the transducer array.
