Abstract: A device for measuring the spring rate of a golf ball is disclosed. The device receives a golf ball between a first anvil and a second anvil. A force gauge is provided on one anvil. A displacer is provided on another anvil. Each anvil defines a ball receiving depression that is larger than the dimples of the golf ball to be measured for negating measurement effects due to golf ball dimples when measurement of the golf ball is conducted. The displacement an anvil is determined. From the force data and displacement data, a spring rate of the golf ball can be calculated and a compression scale value may be calculate and displayed on the device for informing a golfer that is operating the hand held device.

Abstract: A force gauge assembly used to measure forces or spring rate of an object utilizing a diaphragm strain gauge for mechanically compensating for loads not being centrally applied to the gauge. The construction of the gauge provides readings that will be substantially the same as if the load were applied in perfect alignment. The gauge utilizes internal components that remain the same even though the force gauge is adaptable for measuring different objects.
