Abstract
Abstract The invention provides a golf putter having a head of generally triangular shape in plan view with a substantially vertical striking surface and a bottom surface curved to prevent scraping of the ground surface on either putting or transverse movement. Marking means facilitating alignment of stroking movement with the ball are provided, together with means for positioning the shaft at an angular position with respect to the plane of the head.

A golf club for use as a putter, comprising a head and a straight shaft, the head comprising a generally flat base which is shaped as an equilateral triangle with two outwardly curved side edges, a first flange connected to the base at the third edge thereof and extending upwardly therefrom and having a flat uninterrupted substantially vertical exterior surface forming a striking face the length of which is substantially equal to the diameter of a golf ball, a second flange extending upwardly from the base at substantially a right angle thereto and at its one end intersecting the midpoint of the first flange at a right angle and at its other end terminating at the apex of the base which is opposite the first flange, the base of the head having a lower surface which is downward convex both in the direction of striking movement of the club and transversely thereto and has a smaller radius at and adjacent each of the edges than at and adjacent its center, and three fore-and-aft extending lines on the upper surface of the first flange and extending in the direction of striking movement of the club, one line being at the transverse mid-point of the first flange and also extending along the length of the upper surface of the second flange, and the other two lines being on opposite sides of the one line and equi-distant therefrom and being spaced apart a distance substantially equal to the diameter of a golf ball, a two part hostle extending upwardly from the base, the hostle comprising a solid, vertical base portion integral with the second flange and extending equi-distant on either side of the flange and equi-distant from the first flange and the apex of the base and terminating at the upper edge of the second flange and a shaft receiving portion extending from the base portion and inclined to the base portion of the hostle to receive the shaft which is angularly disposed relative to the base of the head.
