ABSTRACT:
The disclosure relates to a balancing means for a weighing scale which compensates for non-linearities in the weighing mechanism to thereby render the scale platform displacement load weight relation linear. The balancing means includes a rotatable wheel which is coupled to the scale platform for rotating with platform displacement. A shaft having an axis of rotation concentric with the rotatable wheel axis of rotation and a plurality of radially extending and arcuately spaced balance weights rotates with the rotatable wheel. As the platform is displaced and the rotatable wheel rotates, the balance weights act upon the weighing mechanism to render the relation between load weight and platform displacement linear.
