  • Patent number: 5335424
    Abstract: An apparatus for measuring radial distances relative to the surface of a cylinder includes a chassis supported on the cylinder by at least three wheels, at least one of which is rotatable about an axis different from the axes about which the remaining wheels rotate, and all of which are spaced from one another in a direction parallel to the longitudinal axis of the cylinder. A gauge is provided for measuring radial distances relative to the surface of the cylinder when the chassis is supported on the cylinder by the wheels, the gauge being supported on the chassis in such a way as to allow adjustment both of the height of the gauge relative to the chassis and of the position of the gauge relative to the chassis in a direction parallel to the axis of the cylinder.
