  • Patent number: 5816579
    Abstract: A marksmanship and weapons training mannequin is disclosed which employs a lifesize mannequin torso in place of the traditional paper targets. The mannequin torso provides more realistic training and provides anatomically correct aiming references. The mannequin is made from an outer skin filled with a flexible interior foam. The outer skin is formed from a flexible material which returns to its original shape even after a projectile passes through it. This resilience allows the mannequin to absorb thousands of rounds and still remain useful as a training tool. Further, the three dimensional nature of the mannequin allows training in realistic circumstances and from angles not possible with paper or hard plastic targets.

  • Patent number: 5584767
    Abstract: A finger insert having a wear indicator and adapted for installation along the wear surface in a finger hole of a bowling ball. The insert is a composite structure formed of a polymeric material and has a primary layer of a first color and a secondary layer of a contrasting second color. When installed in the finger hole, the primary layer is disposed adjacent the bowler's finger. As the primary layer wears away as a result of repeated bowls, the contrasting second color of the secondary layer becomes visible to indicate that the finger insert has served its useful life and should be changed.

    Abstract: A hollow rubber play ball is disclosed that uses a combination two or more fillers to produce desirable playing properties in a tennis ball as specified by the International Lawn Tennis Federation (ITF). The preferred play ball is a pressureless tennis ball. The specific fillers disclosed are mineral type particulate reinforcing fillers such as silicas and carbon black, polymeric fillers such as cellulose, a reaction product of grafting polyethylene with cellulose, and ethylene-vinyl acetate copolymers. These fillers can also have surface treatments to enhance the elastomer-filler interaction. Another reinforcing filler that can be introduced with the rubber components is the non-rubber constituents in skim rubber that serve to increase the modulus of a compounded rubber.

    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.
