Abstract
The ball-pitching apparatus of this invention has a ball-holding container affixed to one end of an arm. A baseball can be releasably supported within the container. The arm is pivotally mounted to a base such that opposed ends of the arm may be pivoted with respect to the base. A pitching spring and an arresting spring are affixed to the base. The remaining end of the pitching spring is connected to the arm at a location between the ball-holding container and the pivot point, while the remaining end of the arresting spring is secured to the end of the arm which is opposite to the baseball-holding container. The springs normally bias the arm into a position of rest, and when the arm is yieldably forced to pivot in opposition to the pitching spring, energy is stored therewithin. The springs have respective ends that are anchored to a common point on the base. When the arm is released, the pitching spring accelerates the arm with sufficient velocity to accelerate the ball, so that when the arresting spring arrests the pivotal movement of the arm, the baseball leaves the container and continues to travel through the air.
