  • Patent number: 4530505
    Abstract: A golf club head (12) for a putter or chipper having a sighting device (16, 50, 44, 45) by which the golfer may easily align the club head to maintain its horizontal plane (31) parallel with the putting surface. The sole plate of the club head (12) is relieved by including two ribs (21, 22) extending from club face portion (13) to the rear of the club head to minimize dragging and scuffing on the grass of the putting surface during a stroke. Recesses (24) in the relieved areas are adapted to receive selectable size weights (26) which permit the weight of the club head to be adjusted to suit the individual and to also balance the head or to vary the heel-to-toe weight ratio. One golf club head (60) has a face (63, 70) having a plurality of deep vertical grooves (64, 72) therein between 1/32 and 1/8 inch wide, spaced by ribs (65, 71) to reduce the impact area of a golf ball with the golf club face (63, 70) to reduce back-spin and skidding of the golf ball.
