ABSTRACT:
A weigh block assembly is disclosed which utilizes compression load-measuring means interposed between a lower plate attached to and supported by a supporting housing and an upper plate attached to the load to be carried and weighed. The upper plate is freely supported on top of the load-measuring means without lateral restraint so that horizontal forces are not absorbed and the pure vertical force is sensed by the load-measuring means and the weighing inaccuracies and other undesirable and unpredictable effects caused by horizontal restraints on the upper plate are eliminated.
