Abstract: A ball feeding device for a for connection to a separate and independent ball propelling machine, such as those used to propel softballs, tennis balls, and baseballs. The preferred embodiment includes a lower chute connected to the feed port of a ball machine. Balls are delivered to the lower chute from a hopper through a feed port comprising of a tumbler casing of a hollow tube formation having an entry hole on its open upper end and a feed hole on its open lower end. The casing has a tumbler hole on its wall leading to the feed port. A tumbler sleeve is positioned in the tumbler hole and axial extends perpendicular to the path of the feed port. The tumbler sleeve has a ring gear around its circumference. The tumbler sleeve also has a semicircular sleeve extension, having an inner and outer wall which extends a predetermined distance into the feed port and obstructs the passage of balls though the port. The upper end of the casing is placed within the exit hole of the hopper.

Abstract: A ball feeding device for a for connection to a separate and independent ball propelling machine, such as those used to propel softballs, tennis balls, and baseballs. The preferred embodiment includes a lower chute connected to the feed port of a ball machine. Balls are delivered to the lower chute from a hopper by a tumbler which revolves below the exit hole of the hopper, dispensing one ball at a time. The tumbler has a tumbler hole or plurality of tumbler hole cut onto its body leading to a separate and distinct chamber or chambers. The tumbler revolves within a tumbler casing which has an entry hole on its upper wall and a load hole on its opposite wall. A collar surrounds the entry hole. The collar is placed within the exit hole of the hopper. A turnstile ring with two vertical posts surrounds the collar causing the balls to be mixed, sorted, and dispensed into the exit hole as the ring rotates.

Abstract: A forced air handling system filter is provided including an inwardly opening, channel-shaped peripheral frame from which corresponding peripheral portions of a panel-like filter batt is supported and an elongated bar of scented material is provided and stationarily supported within a pocket of the frame opening inwardly of the inner periphery thereof. The bar includes a scent impervious cover completely enclosing the bar and one longitudinal edge of the bar projects outwardly of the aforementioned pocket toward the remote side of the frame and that portion of the cover disposed over the bar marginal portion includes a tear strip extending longitudinally thereof. The tear strip is adjustably tearable from the remainder of the cover to expose a corresponding portion of the bar for scent release therefrom.
