The opposite end of the shaft is provided with a double headed cup arrangement for supporting a conventional golf ball. Each cup is formed with a hemispherical surface corresponding to the contour of a golf ball. The apex or center of one such surface lying on the longitudinal axis of the shaft and the other such surface having its apex or center at a forty-five degree angle with respect to the longitudinal axis of the shaft.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
192 words
A golf tee comprising the combination of: a single, elongated shaft having one end which is tapered to terminate in a point; said shaft having an opposite end which is provided with a double-headed cup-like arrangement for selectively supporting a golf ball; each of said cup-like arrangements having a concave surface for supporting a golf ball; a selected one of said concave surfaces having its center lying on the central longitudinal axis of said shaft and said other concave surface having its center lying on an axis angularly displaced thereto; said double headed cup-like arrangement includes a pair of thickened portions integral with said shaft and each portion having a central axis; the central axis of one of said portions lying on and concentric with the central axis of said shaft and the central axis of the other of said portions lying at a 45 degree angle to the central axis of said shaft; a selected one of said thickened portions supports a golf ball; and the other of said thickened portions adapted to receive and transfer insertion loads into said shaft during an implanting procedure of said shaft into the ground.
Claim 2
Dependent Claim
