Abstract: Geometrical tennis lanes are disclosed which comprise a plurality of pie-shaped lanes forming a circle or a semi-circle or substantially circular configuration, the lanes are substantially triangular in shape. The tennis lanes particularly provide for upright-side targets that are strategically positioned so as to indicate if a hit tennis ball would be in or out of court on a full-sized tennis court. The lanes additionally provide a central target area simulating a standard net, top band of the net and area above the net. In addition, a tennis net is provided that is removably connected between two side wall support posts to simulate the area in a normal court for hitting volley shots. Each tennis lane is separated from other lanes by side walls, thus allowing a number of players to practice simultaneously. Additionally, each lane is equipped with tennis ball-throwing means and a simple means for automatically collecting tennis balls.

Abstract: An automatic tennis ball feeding and serving apparatus comprises a ball hopper, wheel-type tennis ball projector and conveyor for transporting tennis balls from the hopper to the ball projector. A frame is provided to which the hopper, ball projector and conveyor are fixed, with the ball projector elevated above the hopper. The conveyor includes an endless loop, motor driven conveyor chain which is inclined at a small angle from the vertical. A ball delivering chute is positioned between the conveyor and the ball projector to gravity feed balls from the conveyor to the ball projector. Connected to the conveyor chain are a plurality of spaced apart, tennis ball transporters, each having a shallow ball receiving recess. Associated with each ball transporter is a ball anti-stacking element which prevents the stacking of two or more tennis balls on the same ball transporter. Each anti-stacking element projects outwardly from the conveyor belt about 11/2 tennis ball diameters above each ball transporters.
