ABSTRACT:
The present invention can be described as a ball pitching machine having an integral pitching barrel and motor mount and three spaced drive wheels partially projecting into the barrel to grip and propel a ball placed in one end of the pitching barrel. The barrel has three longitudinally aligned slots or windows in the surface of the barrel to provide clearance for secant portions of each of the three wheels. The planes formed by each drive wheel extend radially from the longitudinal axis of the barrel. Each radial plane is equally spaced from each other at 120 degrees relative to each other. Each domed drive wheel is rotatably mounted on the end of a rotatable drive shaft of an electric motor. The three electric motors are mounted on the integral pitching barrel and mount by C-shaped clamps. The barrel is supported by a wheel mounted frame, a pair of U-shaped brackets secured to the frame in an opposed facing relationship, a front support ring for rotatably securing the ejectment end of said ball pitching device, and a rear support ring for rotatably securing the feed end of the ball pitching device. The front support ring and the rear support ring are mounted in a spaced apart relationship between the opposed facing U-shaped brackets to form a generally open rectangular-shaped support member for rotatably mounting and adjusting vertical angle of the ball pitching machine.
