Abstract:
A sphericity device for evaluating the quality of a golf ball with respect to its diameter and for detecting damage to its periphery comprising:a ring having a first side corresponding to an upper surface, a second side corresponding to an underside surface, and a centralized hole of a diameter slightly greater than the standard diameter of a golf ball, said hole defined by an inside edge extending between said upper and underside surfaces, said inside edge including a midpoint thereon;a bridging device extending across said hole only between two diametrically located points on one of the upper and the underside surfaces of said ring,said bridging device including an inward-facing surface which acts as a support for a golf ball placed in the hole of said ring, wherein said inward-facing surface is positioned relative to one of said upper and underside surfaces of said ring such that a distance between inward-facing surface of the bridging device and the midpoint of the inside edge is equal to a radius of the ball, whereby said golf ball may be manipulated from either side of said ring so as to rotate the ball about various axes thereof to check ball sphericity by the consistency or variance in distance between the inside edge and the periphery of the ball.
