  • Patent number: 4884813
    Abstract: A golf club alignment device for recording a sight pattern showing the optimum position of the handle end of a golf club when held by a golfer addressing the ball and for reproducing that position. The device has a sighting barrel that is attached to the shaft of the club in spaced-apart, generally parallel relation. Adjustable linkages between the sighting barrel and the clamp attaching it to the shaft allow movement of the top of the barrel toward and way from the shaft and to the golfer's left and right. The barrel is moved until sets of cross hairs across its top and bottom come into alignment with one another when viewed from above by the golfer. The resulting adjusted barrel position, reflective of optimum location of the club handle, is maintained by securing the barrel against further movement. In subsequent shots, the golfer addressing the ball moves the club handle up or down and to the left or right until the sets of cross hairs are again brought into alignment.
