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.

Device and method of throwing objects

A linear to rotary motion transmission device comprises a reciprocal rack having a plurality of ratchet teeth engageable with flexible pawls of a rotary pinion. Reciprocation of the rack in one direction causes driving engagement between the pawls and the teeth for rotatably driving the pinion, and reciprocation of the rack in an opposite direction causes the flexible pawls to slide over the ratchet teeth in non-driving engagement.

Motion transmission device

A connection between a handle and a valve stem is provided by a snap latch arrangement. The usual button at the top of the handle carries a dog bar that prevents the detent from releasing when the button is in place. But when the button is removed, the handle is automatically removable by upward force. No attachment screw need be manipulated. When the handle is removed, a cartridge can be removed. The cartridge includes a frontally facing segment that fits into the cylindrical contour of the valve body cup. The segment is snapped outwardly whereupon the segment, together with associated valve parts can be lifted from the valve cup for repair or replacement.
