An instrument consisting of two branches or legs which are pointed at both ends and joined by a sliding pivot, the position of which may be so adjusted that the ratio of the distance between one pair of points and the pivot and the distance between the other pair of points and the pivot may be varied. This combination produces the variable ratios. Used for making proportional transfer of measurements.
