ABSTRACT:
A ball throwing apparatus includes an enclosure formed with an aperture and a movable gate to cover the aperture. A throwing arm adapted to receive a ball is pivotally mounted within the enclosure for movement between a ball loading position and a released position. A suction cup element holds the throwing arm in the ball loading position and releases the throwing arm from the ball loading position after a time delay. When released, the throwing arm is biased by a spring to move from the ball loading position to the released position to throw the ball. At the same time, movement of the throwing arm acts to open the gate to allow discharge of the ball from the enclosure. The use of a gate makes the ball throwing apparatus safer by enclosing the moving parts of the apparatus to make them inaccessible when in use.
