ABSTRACT:
The invention relates to an improved batting machine which presents a batter with a ball which is swung around in a generally circular path. The invention was designed to swing the ball in either a horizontal path or a path which is offset from horizontal. The ball is connected to an extended arm via a tether. The extended arm is also connected to a vertical shaft. The shaft is rotated by an electric motor means, along with a centrifugal clutch. The motor is able to rotate the shaft in either clockwise or counterclockwise direction, thus giving the batter the opportunity to bat right and/or left handed. The shaft motor assembly is supported by a plurality of adjustable supports.
