Abstract: 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.

Abstract: A water faucet inlet line connector for providing a quick and reliable attachment of an inlet water line to the shank of a water faucet is disclosed. The connector is comprised of an assembly of two body members entrapping a conical spring washer therebetween. The upper body member has a tapered outer surface for cooperating with the conical inner surface of the connection end of the faucet shank, and preferably includes on its inner cylindrical diameter a ring-like inward protrusion to provide a ring-like region of increased pressure against the inlet tube when the connector and tube are finally locked in position. The lower body member also has a cylindrical inner surface, and cooperates with the upper body member to retain the conical spring therebetween, to align the water line and to provide a stress relief to help isolate inlet line motion from the region of the conical spring and the upper body member.
