ABSTRACT:
Tennis balls are sequentially fed to an entranceway in the top of the plenum chamber of a pneumatic throwing machine by a flexible disk which rotates about a vertical axis. The balls roll by gravity down a chute onto the feed disk which has angularly spaced pocket holes. To prevent jamming of unpocketed balls between the top of the feed disk and the feed chute, the disk is sufficiently flexible as to be deflectable by an unpocketed ball and be discharged through an open escape path.
