Patent abstract
An apparatus for underhand tossing of a ball includes a cabinet with a hollow tossing arm pivotally coupled thereto. A mechanism is provided to dispense a single ball at a time from a supply of balls into the hollow tossing arm. A spring is affixed at one end to the hollow tossing arm and affixed at a distal end to the cabinet at a point forward of the hollow tossing arm. A machine is provided for pulling a distal end of the hollow tossing arm toward a back end of the cabinet and releasing the hollow tossing arm such that the distal end of the hollow tossing arm swings forward, releasing the ball at a point at which the hollow tossing arm hits a stop peg.
