发明名称 Baseball dispenser device for batting practice
摘要 A baseball dispensing device for practicing batting that includes a three tubular chute for retaining and delivering baseballs to a hitter. The center tube contains an electric driven motor which rotates a pair of discs which dispense baseballs at timed intervals releasing them to a central tube established at an incline to allow the dispensed ball to roll and strike a spring. The weight of the ball causes the spring to flex and upon reflex propels the ball upward vertically allowing a batter to swing into the ball. The center motor driven discs are equipped with a hole which when completing a rotation dispenses balls alternately to the delivery chute.
