ABSTRACT:
A toy baseball pitching machine that is particularly adapted to be used by children. The machine has a ball pitching arm that oscillates rather than rotates and is capable of pitching a plastic ball to a batter using an "underhand" method of pitching. The ball pitching arm is fixed to an oscillatable eccentric arm. The eccentric arm is connected to one end of an extension spring, and the arm carries a pivoted pawl. The pawl is engaged by a toothed rotating drive wheel to rotate the pitching arm in one direction toward a cocked position with the spring extended. Further rotation of the drive wheel brings the pawl into contact with a stop to pivot the pawl out of engagement with the drive wheel. The extended spring then acts on the eccentric arm and pitching arm to rotate the pitching arm in the opposite direction to engage and pitch a ball. The drive wheel, pawl, eccentric arm, stop and extension spring are all mounted within a housing; and the pitching arm is outside the housing. The machine has a ball storage rack so it is capable of pitching a plurality of balls and is battery powered and includes an automatic shut-off switch, which shuts the pitching machine off when all balls are pitched.
