US Patent 7032583 Ball throwing apparatus

The present invention discloses a device for throwing a ball. The pouch is disposed on the end of an arm so that the ball contained in the pouch can be thrown in an overhand or underhand manner by the user. The pouch is attached to the arm on one end and a rubber band-like member is disposed in the pouch on the other open end, which rubber band holds the ball inside the pouch. As the arm and pouch are thrown by a user, the ball gains enough inertia through the arc of the throwing motion that the ball stretches the rubber band and passes between the rubber band and the pouch and, therefore, exits from the open end of the pouch.
