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.

Claims

1. A golf club head comprising:

a golf club head body having a front ball striking face thereon;

a plurality of recessed slots in said face, each slot being between 1/32 and 1/8 inch wide and of a depth to prevent the bottom of the slot from contacting a golf ball upon impact with said striking face, each slot extending substantially vertical across the center of said striking face, thereby reducing the contact area engaging a golf ball, said golf club head body having a horizontal plane normal to the striking face thereof;

sighting means disposed in a top surface of said golf club head for visually determining when said horizontal plane is parallel with the putting surface, said sighting means having an index adjacent the ball striking face; and

said body having a sole plate extending rearwardly from the striking face and at least three relieved areas in said sole portion disposed rearwardly from said front striking face and extending to said rear edge, said relieved area defining at least two ribs forming the rearwardly extending portion of said sole plate, thereby minimizing the area of the sole plate which will be in contact with the surface during a stroke.
