  • Patent number: 6679239
    Abstract: Apparatus for throwing a football includes a pivoting arm supporting the ball and a spring, which preloads the arm to pivot upward and release the football. The arm is rotated manually to a ready-to-throw preloaded position, where the arm is latched by a plunger and released to pivot and launch the ball in response to a command signal transmitted at a distance from the apparatus by a player awaiting the ball. The command signal causes an electric power source to energize a solenoid, whereby the plunger releases the arm, the spring pivots the throwing arm forward, and the ball travels an airborne path to the player.
