ABSTRACT:
An apparatus for measuring the contours of a railroad wheel which contains a tool slide, a measuring arm pivotally attached to the tool slide, a measuring wheel rotatably attached to the measuring arm, a device for moving the measuring arm horizontally, vertically, and pivotally, a marker, an optical sensor, and a device for sensing the movement of the measuring arm. The apparatus also contains a first encoder for determining the degree to which the measuring arm moves during any particular time during the rotation of the railroad wheel in any particular rotation cycle, and, additionally, a second encoder for determining at what point in said particular rotation cycle said measuring arm has moved.
