ABSTRACT:
A golf ball teeing apparatus which utilizes a double-threaded shaft and its attendant pawl assembly as a mechanism to elevate replacement golf balls sequentially from a supply tube and hopper to a driving position, automatically, as the tee element and prior golf ball are struck by the golfer. When struck by a golf club, the spring-loaded tee element tilts forward causing the lower curved end of the tee element to strike a pressure-sensitive microswitch which, in turn, closes a holding relay actuating the fractional horsepower electrical motor for an operating cycle. The geared-down fractional horsepower motor slowly rotates the double-threaded shaft to which it is coupled, thereby lowering the pawl assembly and the piston supporting the tee assembly to the ball receiving position. At that point in the cycle, a golf ball is fed by gravity from a supply tube and nearby hopper onto the tee element. Then, in one continuous motion, the reverse thread of the rotating double-threaded shaft raises the pawl assembly, piston and tee assembly back up to the fully teed-up or driving position where a second microswitch is struck by a pin on the pawl assembly, opening the holding relay and stopping the fractional horsepower motor.
