ABSTRACT:
A machine for tossing or set ting a volleyball into the air, to aid in practice of spiking the ball, includes a cylindrical housing with a ball exit opening at one end, with legs to set the housing on the ground with the exit opening facing upward. A ball support cup with attached rod is slidably supported in the housing by a linear bearing. The ball support cup is spring biased toward the exit end; a brake prevents the rod from passing completely through the bearing. The lower end of the rod includes teeth which are engageable with a sprocket wheel of a timer assembly. When a ball is placed on the support cup, and the cup is pushed down, the teeth will engage the sprocket wheel to activate the timer; after a time, the sprocket wheel will disengage from the teeth, allowing the spring to move the support cup upward to launch the ball through the exit opening.
