Abstract: An apparatus for accurately measuring a variety of objects of disparate shape, having a substantially flat plate-like stationary member fixed to a base member and second, substantially flat plate-like movable member facing the surface of the first member and mounted for movement toward and away from the first member. The opposing plate-like surfaces of the first and second members are maintained substantially in parallel with each other and are dimensioned to make contact with the outermost surface part of an object to be measured in a given orientation of the object. Means are provided for accurately measuring the distance between the plate-like surfaces when an object is placed between the first and second members. The movable member is normally biased for movement toward the fixed member.
