  • Patent number: 4741537
    Abstract: An apparatus for semiautomatically teeing up golf balls utilizing very low air pressure as an operating medium. Balls are loaded onto a contoured dish at the upper end of an open ended upright cylinder and pass from the dish into a flexible tube wrapped helically around the outside of the cylinder. The lower end of the tube is blocked by a ball dispenser. When a user trips a lever on the ball dispenser, one ball is permitted to roll to a stop above a hole in the hitting mat directly above the air operated teeing device. The teeing device includes a teeing tube attached vertically above an expandable chamber and extending just to the top surface of the hitting mat. A very low pressure stream of air constantly flows through the chamber and escapes via the teeing tube. When a golf ball comes to rest above the teeing tube, the escape of air is terminated, causing the expandable chamber to fill, thereby raising the teeing tube and the ball to the teed height.
