    Abstract: A tennis ball dispensing device for practicing tennis strokes that includes an inclined tubular chute for retaining and delivering balls to a flexible sock having an opening therein for permitting release of a ball therethrough, the sock being suspended from a pivotal ring located at the lower end of the chute. The balls move to the end of the chute under the force of gravity and are delivered into the sock to be releasably held therein as a result of the racket's striking the ball held in the sock, the ball being driven from the sock as a result of the racket striking the sock and ball. A ball escape indexing mechanism releases one ball at a time into the net as a result of pivoting of the ring when the ball and sock are struck by the racket.
