  • Ball suspending apparatus and method
    Patent number: 4858921
    Abstract: Disclosed is an improved ball suspending apparatus which utilizes a dual directional component air stream to support the ball for striking. The dual directional component air stream allows the ball to be spun according to the desire of the operator. For example, a baseball may be supported to simulate the certain spins associated with fastball or curveball pitches thrown by either left or right handed pitchers, thereby allowing the batter to experience the manner in which a certain type of pitch will react when struck with a bat.
