ABSTRACT:
Ball inflating apparatus automatically operable through succession of cycles in each of which a ball inflation needle is momentarily exposed for reception of an end of the same through apertured valve housing of an inflatable ball of stretchable material. In each cycle the ball is also engaged between spaced ball sizing means. Simultaneously with each successive withdrawal of the needle from the valve housing, slide members reciprocated in fixed support base operable to present air sealing device in path of reciprocatable plunger, to urge the sealing device into valve housing aperture for retaining air in the inflated ball. With each withdrawal of inflating needle from fully inflated ball and after insertion of sealing device, full distention of inflated ball actuates ball sizing means to release inflated ball and initiate next successive ball inflation cycle.
