A ball launching apparatus comprises a ball propulsion mechanism for propelling a ball and a ball feed mechanism for intermittently feeding balls to the ball propulsion mechanism. The ball feed mechanism has a rotatable wheel defined by at least a first member and a second member. The wheel has a recess therein for receiving a ball being fed to the propulsion mechanism. The recess is located between a surface of the first member and a surface of the second member. The second member is moveable with respect to the first member in a direction opposite to a direction of rotation of the wheel to increase a size of the recess for receiving larger a ball. A method of feeding balls to a ball propulsion mechanism is also provided.

Un appareil lanceur de balle comprend un mécanisme de propulsion de balle pour propulser une balle et un mécanisme d'alimentation de balle pour alimenter des balles par intermittence au mécanisme de propulsion de balle. Le mécanisme de propulsion de balle est muni d'une roue rotative défini par au moins un premier élément et un deuxième élément. La roue est dotée d'une cavité pour recevoir une balle étant alimentée au mécanisme de propulsion. La cavité est située entre une surface du premier élément et une surface du deuxième élément. Le deuxième élément est mobile par rapport au premier élément dans une direction opposée à la direction de la rotation de la roue pour augmenter une taille de la cavité pour recevoir une balle plus large. L'invention concerne aussi une méthode d'alimentation de balle à un mécanisme de propulsion de balle.
