ABSTRACT:
A scale for measuring total weight/top weight of a bowling ball includes the utilization of a pair of electronic load cells supporting a moment transfer plate with the load cells being connected to a meter. In one form of the invention, the ball is centered over the load cells with its heavy spot in predetermined alignment so as to affect one load cell differently than the other. The ball is weighed simultaneously by both load cells, the total weight is determined by adding the outputs and the difference in output is used by the meter to calculate the top weight which is displayed. In another form of the invention, both a top weight and a total weight load cell are provided and the meter calculates the top weight directly from the top weight load scale.
