A golf putter with an adjustable sighting device to improve accuracy of putting, particularly on hilly terrain. A directional dial is fixed above the club head with a pointer just below the dial being rotatable by the golfer to different positions relative to the dial to fix a direct line between the ball and the cup independently of the angular position of the club head. The pointer is carried in a horizontal position generally at right angles to a rod that rotates in a bore within a tubular fitting by which the club shaft is secured to the club head. A steel cable coaxially secured to the rod extends telescopically through the hollow club shaft to a rotary cap or knob on the upper end of the club shaft by rotation of which the golfer is able to adjust the pointer relative to the dial to obtain a directional fix on the cup. Thus, independently of the terrain, the golfer may stroke the club head on a line coincident with the direct line to the cup enabling the angularly disposed club head to strike the ball appropriately to cause the ball to take a curved path to the cup compensatory to the amount of lateral slope on the green. In a modified embodiment, a pointer is permanently fixed to the club shaft in a position perpendicular to the face of the club head.
A golfing putter having a club head and a shaft therefor, wherein the improvement comprises a pointer supported in a generally horizontal position on the shaft of the club above the club head, and means for adjusting the angular position of the pointer with respect to the face of the club head, and wherein the shaft is tubular and fits telescopically over a cylindrical element attached radially to the club head, and wherein said element has a longitudinal bore and a rod rotatable therein, said pointer being carried by said rod in a position at a right angle to the said rod.
A golfing putter having a club head and a shaft therefor, wherein the improvement comprises a pointer supported in a generally horizontal position on the shaft of the club above the club head, and means for adjusting the angular position of the pointer with respect to the face of the club head, and wherein the shaft is tubular, and wherein the means for adjusting the angular position of said pointer comprises a knob at the upper end of the club shaft and a flexible shaft within said club shaft connecting said knob to said pointer.
A golfing putter having a club head and a tubular shaft therefor, wherein the improvement comprises a tubular element intervening between said shaft and the club head, said tubular shaft fitting telescopically over one end of said tubular element, the other end of which is attached to said club head whereby the shaft is attached to the club head, said tubular element having an external annular shoulder thereon, and an annular disc supported coaxially on said shoulder and held fixed thereon by the end of said shaft fitting telescopically over said one end of the tubular element bearing against said annular disc on said shoulder, said disc having angularly spaced gradations, and a pointer rotatably supported on said tubular element for adjustment relative to the gradations in said annular disc.
