ABSTRACT:
An improved ball projecting apparatus for balls of various sizes, weights, materials and shapes, which utilizes air pressure supplied by a separate and independent source of flowing air, such as a leaf blower, to project balls. More specifically, it comprises of 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 through the casing and into the barrel. Inside the casing is a tumbler (20) being of hollow tubular shell formation which is solid on all walls and ends except for a tumbler hole (22) formed on its wall, exposing the tumbler chamber into which a ball is deposited. This tumbler is capable of being revolved within the casing. The tumbler has a driveshaft (23) attached which is turned by an electric motor (24). A collar (21) surrounds the entry hole and holds a ball in place above the hole. A ball is placed above the entry hole within the collar. As the tumbler revolves within the casing the tumbler hole aligns itself alternately with the entry hole and the feed hole of the tumbler casing. The ball drops into the tumbler when the tumbler hole and the entry hole are aligned. The tumbler continues its revolution. The ball is loaded into the barrel when the tumbler hole and the feed hole are aligned. The tumbler and tumbler casing continuously maintain an obstacle to air loss through the barrel hole, reducing air pressure release from the air source through the barrel hole and permitting a ball to be loaded from atmospheric pressure. When the ball drops into the barrel it is propelled out the open end of the barrel by the source of flowing air.
