  • Patent number: 5733209
    Abstract: A pneumatic ball launching apparatus propels a ball vertically upward into mid-air without imparting spin on the ball. A pneumatic cylinder is disposed vertically below the top surface of a ground supported platform in axial alignment with the center of an aperture in the top surface of the platform. The pneumatic cylinder has a spring return piston rod with a cup-shaped ball holder secured to its outer end. The cylinder is connected through a valve to a source of pressurized air and the valve is controlled by a timing device. The platform has a downwardly inclined forward portion which slopes inwardly and downwardly from each lateral side to form a central low portion at its forward end. A net extends vertically upward from the forward portion of the platform to catch balls which have hit.
