ABSTRACT:
A soccer ball practice machine includes a pair of juxtaposed, oppositely rotating wheels for propelling a soccer ball toward a soccer player to facilitate the practice and instruction of a wide variety of soccer skills. The orientation of these wheels can be selectively varied to permit the soccer ball to be propelled in an infinite number of directions. In addition, the distance separating the rotating juxtaposed wheels can also be adjusted to accommodate soccer balls of varying diameters and can be automatically increased to prevent damage to oversized balls due to engagement by the wheels. A large hopper includes a rotating auger which successively feeds soccer balls in the hopper into a flexible feed tube and down a rigid ball chute where they are engaged by the wheels and propelled outwardly. The flexibility of the feed tube and the rigidity of the ball chute provide accurate delivery of the balls to the wheels and confinement of the balls on all sides as they are engaged and propelled by the wheels, even though the positions of the wheels relative to the hopper may be changed to vary the direction of the ball's flight.
