Gunter's scale
Gunter's scale Gun"ter's scale` A scale invented by the Rev. Edmund Gunter (1581-1626), a professor of astronomy at Gresham College, London, who invented also {Gunter's chain}, and {Gunter's quadrant}. [1913 Webster]

Note: Gunter's scale is a wooden rule, two feet long, on one side of which are marked scales of equal parts, of chords, sines, tangents, rhombs, etc., and on the other side scales of logarithms of these various parts, by means of which many problems in surveying and navigation may be solved, mechanically, by the aid of dividers alone. [1913 Webster]
