An improved ball projecting apparatus which utilizes air pressure supplied by a separate and independent source flowing air, such as a leaf blower, to project balls. More specifically, it comprises a barrel (10) of tubular form defining a linear air discharge axis. The barrel is attached on one end to the source of flowing air (11). A barrel hole (12) is formed in the barrel wall. Attached to the barrel is a tumbler casing (14). The casing has a hollow tubular formation. It has an entry hole (16) and a feed hole (19) formed on its wall directly opposite each other. The tumbler casing is attached and sealed at its feed hole to the barrel hole creating a path or feed port into the barrel. Revolution of the tumbler feeds balls into the barrel while continuously maintaining an obstacle to air loss through the barrel hole.

L'invention concerne un appareil de projection de balles amélioré faisant appel à une pression d'air fournie par une source séparée et indépendante d'air fluide, telle qu'une soufflante à feuilles, pour projeter des balles. Plus spécifiquement, l'appareil comprend un magasin (10) de forme tubulaire définissant un axe de sortie d'air linéaire. Le magasin est fixé à une extrémité, à la source d'air fluide (11). Un trou (12) est formé dans la paroi du magasin. Un boîtier de tambour (14) est fixé au magasin. Le boîtier présente une forme tubulaire creuse. Il possède un trou d'entrée (16) et un trou d'alimentation (19) formés sur sa paroi et directement opposés l'un à l'autre. Le boîtier est fixé et scellé par son trou d'alimentation au trou du magasin, ce qui crée un orifice d'alimentation dans le magasin. La rotation du tambour permet d'introduire des balles dans le magasin tout en maintenant en continu un obstacle à la perte d'air par le trou du magasin.
