  • Patent number: 4251074
    Abstract: An improved pitching mechanism and ball construction for miniature baseball games of the table-top variety. A pitching arm protrudes through an opening in the playing surface at the pitcher's mound from below. A horizontal pin at the upper end of the pitching arm extends toward home plate and is formed for slidable mating engagement within a conforming bore in the ball which is constructed of a lightweight material such as balsa wood. The pitching arm is pivotally rotatable in a vertical arc to provide a range of angular ball release positions combining various amounts of elevation above the playing surface and horizontal distance from an imaginary line between the pitcher's mound and home plate. The pitching arm is retractable away from home plate against the action of a spring such that increasing amounts of retraction provide greater speed of the ball upon release.
