<p>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.</p> |
