Abstract: An apparatus for testing the compressability of golf balls and sorting them in accordance with predetermined compression ratings. The apparatus includes a golf ball movement path having a rotary anvil on one side thereof for driving the golf balls one at a time through a restricted gap between the anvil and a deflectably biased lever. The gap is sized to be smaller than the diameter of the golf balls so that they will deflect the lever an amount determined by their individual compressability. The amount of lever deflection is sensed and transmitted to an electric circuit which operates a golf ball sorting device that directs the golf balls to different outlets in accordance with their sensed compressability.
