ABSTRACT:
A weighing scale apparatus including a base and a scale platform and a plurality of bell cranks pivotally mounted on the base at locations angularly spaced apart about a common center for pivotal movement in planes generally tangent to a circle about the common center. A load summing member is connected to the bell cranks at locations vertically offset from the pivot axes for turning thereby about the common center, and the scale platform is connected ot the bell cranks at locations horizontally offset from the pivot axes of the bell cranks in the same angular direction relative to the common center to apply a turning moment to the load summing member correlative with the load on the scale platform. The turning moment applied to the load summing member is sensed as an indication of the load on the scale platform.
