US Patent 8028684 Device and method of throwing objects

A throwing device has a head for holding an object to be thrown on its distal end. Located near to the head is a catapulting mechanism that is used to further the distance. The catapulting mechanism comprises one or more catapulting devices. A plurality of these catapulting devices may be included thereon, and the flexibility of the spring-like member may be varied as required or desired. During the swing, the weight of the tennis ball and the head cause the spring-like member(s) to rearwardly flex. The user determines when to slow the swing of the head which causes one or more of the catapult devices to decelerate the head with the tennis ball therein wherein a hammer of the catapult device hits a stop and thereby transfers a significant degree of kinetic energy into the motion of the released ball to obtain the greater distance.
