ABSTRACT:
A mechanical averaging gauge for averaging displacements at a plurality of locations along the surface of an object. The gauge includes a measuring unit which is urged into contact with the surface of the object. Several probes extend from the measuring unit and rest on the surface of the object. The probes are interconnected by means of cylindrical sliding members in contact with the rear of each of the probes. Trapezoidal sliding members are disposed between the cylindrical members so that the displacement of the measuring unit from a reference surface is the average of the various displacements of the individual probes. The arrangement also results in each probe contacting the surface of the object with substantially equal force. Therefore, the arrangement has application as a clamping device.
