Ball server with delay element for delaying time period of serving a ball

Image Number 3 for United States Patent #6719649.

A ball server includes a server seat, a movable rod inserted into the server seat, an elastomer, a touch plate, and a delay element within the server seat. In using, the movable rod is pressed so as to buckle the touch plate and the movable rod is interacted with the delay element, the ball will flatly place on the movable rod. When the ball server is actuated, the movable rod will be driven by the delay element so that it rises slowly, but after a time period, the action of the delay element is released and the movable rod rises rapidly and at the same time, the ball rises. When the movable rod is operated by the delay element, the batter can prepare for next beating.
