  • Patent number: 5529307
    Abstract: An automatic golf ball dispenser includes a housing having a substantially horizontal top and a plurality of substantially vertical sides. Within the housing is a storage bin and track configured to receive a plurality of golf balls and to deliver the golf balls to a feed mechanism. The feed mechanism includes a meter configured to dispense a single golf ball for each movement of the meter. An arm mounted on a pivot retrieves the single golf ball from the feed mechanism and places the golf ball at a predetermined location for a golfer to hit the golf ball. A sensor is located nearby to indicate when another golf ball should be dispensed. A controller is also contained within the housing and configured to accept currency, where the controller is electrically connected to the sensor and responsive to the sensor, and where the controller is also electrically connected to an arm motor to control the movement of the arm.
