ABSTRACT:
An insert for removable placement within a finger grip bore of a bowling ball. The insert includes members of different resiliencies forming an uninterrupted truncated conical inner wall surface to enhance both ball retention during the swing of the delivery and subsequent ball release. The softer member is located near the inner extremity of the ball bore to receive the pad of the finger's distal phalange. Insert retention in the ball is by a small amount of adhesive which facilitates insert removal and replacement. Modified forms of the insert also each include a member of softer material but of other than tubular shape which member is embedded within a longer insert member of less resiliency. Methods are disclosed for molding each type of bowling ball insert disclosed. A further modified insert additionally includes a chordally disposed mass or formation against which the outermost phalange of the inserted finger bears during ball retention.
