  • Patent number: 5050574
    Abstract: A baseball pitching machine including a metal cart that rides on a plastic elliptical track wherein the metal cart carries a baseball and is controlled by a series of switches that command a rectangular-shaped electromagnet mounted on the plastic track and having an opening. The electromagnet is turned on via a switch and the metal car accelerates toward the electromagnet till it engages a projection mounted on the track which turns off the electromagnet. The momentum gained by the cart then carries the cart to a curve of the elliptical track where the baseball is projected as the cart goes around the curve of the track. After the cart protects the ball the metal cart proceeds along the track to the starting point where the cart is ready to reload with another baseball and the operation starts over with the switching on of the electromagnet.
