Abstract
PURPOSE: To facilitate measurement of the diameter of a circle in which three equidiametral holes are positioned at regular intervals by a constitution wherein a new measuring face is provided outside a jaw of a slider of vernier calipers, and a scale for which the outside measuring face is standardized and another scale of 1.155 magnifications are provided besides a conventional scale for the calipers.
CONSTITUTION: An outside measuring face 7 is provided on a jaw 4 of a slider 2 of conventional vernier calipers besides a conventional inside measuring face 6. A scale 14 equivalent to a conventional scale 13, for which the outside measuring face 7 is standardized is the provided. Both the scales 13, 14 are available for use on a vernier 16. Then, a scale 15 of 1.155 magnifications and its vernier 17 are provided on the upper part of vernier calipers 1. Since a diameter D of a circle passing the centers of three equidiametral holes arranged at regular intervals (vertexes of an equilateral triangle) is given at D=1.155a ("a" being one side of the equilateral triangle), the diameter D can easily be obtained through one time measurement.
