ABSTRACT:
An inexpensive machine which pitches plastic baseballs. The machine is actuated by the user pulling, and then releasing a cord, as he brings his bat into a hitting position. The machine consists of a frame and two legs which form a tripod base, a ball rack containing a number of balls, a shaft attached to the frame, a torsion spring and a pitching arm are mounted on the shaft. A cord is attached to the pitching arm, and passes in the path of the balls restricting their movement until such time as the batter pulls this cord, causing a ball to roll into the arm and also spring loading the pitching arm. Release of this cord causes the machine to pitch the ball.
