  • Patent number: 4714250
    Abstract: A golf ball and tee setter for simultaneously holding a ball and tee prior to inserting a tee into the ground and for releasing the ball and tee with the ball remaining in the teed position subsequent to inserting the tee into the ground. The tee setter has an elongated handle and a pair of opposed cup members pivotally attached to one end of the handled. The cup members are arranged to simultaneously hold a golf ball and tee when in a closed position and to release the ball and tee when in an open position. The cup members are normally held in the closed position by a spring biasing element and are moved to the open position by a hand operated mechanism accessible at the other end of the handle, the hand operated mechanism being attached to the pivoted cup members. The apparatus is so designed that a player may set a ball and tee in place from a standing position.
