  • Patent number: 4312509
    Abstract: A golf putter including a shaft and an integral ball striking head so configured that a player utilizing the putter is automatically caused to place his hands on the handle of the shaft in a region forward of the ball about to be struck. For this purpose, the ball striking head is provided with a pair of parallel lower base elements transverse to the longitudinal axis of the shaft, one adjacent to a forward face of the club head, and one adjacent to the rearward face of the club head. When the shaft is in an upright position and the rearward lower base element engages the ground, the forward lower base element is spaced from the ground. In this situation, gravity tends to cause the shaft to rotate forwardly and downwardly about the rearward lower base element resulting in simultaneous movement of the foward lower base element toward engagement with the ground.
