  • Patent number: 5619977
    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.

  • Patent number: 4907802
    Abstract: A ball throwing apparatus capable of releasing balls at selected intervals and selected trajectories, and operable from a remote location. The apparatus comprises a base and a throwing arm mounted on the base for pivotal movement between a ball loading position and a released position. There is a ball receiving aperture for holding a ball to be thrown mounted on the throwing arm. A suction cup element is positioned to be depressible by the throwing arm so as to releasably hold the throwing arm in the ball loading position. A slow leak is created in the suction cup for releasing the hold of the suction cup element after a short delay to allow the user time to prepare for the throwing of the ball. An actuating spring attached to the throwing arm acts to move the arm from the ball loading position to the released position upon release of the throwing arm by the suction cup element, the movement of the throwing arm between the positions resulting in a throwing motion.
