ABSTRACT:
A ball throwing machine includes a ball throwing mechanism that is mounted on a frame that rotates about a vertical axis so that balls are ejected at preset positions along an arc. In a preferred embodiment, the ball throwing mechanism is mounted on a base plate that rotates back and forth through a 90-degree arc. A timing plate controls the rotation of the throwing mechanism and includes projections that trigger the ejection of the balls at preselected angular positions.
