  • Patent number: 5368293
    Abstract: A housing is provided having multiple openings in its front wall each opened and closed by a closure positioned by a pneumatic cylinder. Each closure, when retracted from its opening, provides a target for the pitcher. A programmable controller in the housing permits the preselection and dwell time of the cylinders to be actuated and for the presentation of an array of targets in and out of a strike zone. A thrown ball impacting a retracted closure momentarily closes a switch to provide a signal to a counter. A ball return mechanism provides a partial vacuum in a ball receptacle at the pitcher's mound to retrieve balls from the interior of the housing. A remote control is provided to permit operation of the apparatus remote from the apparatus housing.
