Abstract
A differential spring mechanism is provided for allowing very fine adjustments of the position of at least one flexure mounting in a weighing scale. Most of the motion of a control device is absorbed by a first relatively weak spring, leaving only a relatively small portion of that motion to be absorbed by a second relatively strong spring to which the flexure mounting is connected.
