ABSTRACT:
A ball projecting machine having a C-shaped arm that provides the ability to adjust the length or elevation of pitched balls. The C-shaped arm connects a ball projecting head to a stand, with the ball projecting head affixed to one end of the C-shaped arm, and the C-shaped arm is slidably engaged through a frame atop the stand to allow rotation of the ball projecting head about a horizontal axis. A center of gravity of the ball projecting head in combination with the C-shaped arm facilitates stability of the ball projecting machine when the C-shaped arm is slid up or down. A locking device, when loosened, allows the C-shaped arm to slide up or down through the frame.
