Abstract

A gold club (either wood, iron or putter) constructed to cause the striking face to be aligned normal to the line of swing both during the swing and at the instant of impact and also constructed to provide, at the instant of impact, a high moment of inertia with respect to the center line, the alignment and inertia characteristic providing for the ball to be hit straight away without hook or slice.

Claims

1. In a golf club:

a head with heel and toe sections and front and rear sides;

a ball striking face formed on the front side with the plane of impact of the head being located between the heel and toe sections and being generally normal to the striking face;

a shaft connected to the head with the projection of the shaft axis extending through the plane of impact;

means on the head forming weight means respectively disposed on opposite sides of the plane of impact and whose mass concentrations are located substantially outwardly from the plane of impact respectively toward the heel and toe sections and also substantially spaced from the projection of the shaft axis in a rearward direction, said disposition of the shaft axis and the location of the mass concentrations being for use in causing the striking face, during the swing, to be oriented generally normal to the line of swing and for use in providing for the head to have, at the moment of ball impact, a high moment of inertia with respect to the plane of impact so as to minimize twist of the striking face; and

said mass concentrations being substantially formed by that the head is formed with a pair of wings respectively disposed on opposite sides of the plane of impact and that there are weights respectively in said wings.

2. In a golf club:

a head with heel and toe sections and front and rear sides;

a ball striking face formed on the front side with the plane of impact of the head being located between the heel and toe sections and being generally normal to the striking face;

a shaft connected to the head with the projection of the shaft axis extending through the plane of impact;

means on the head forming weight means respectively disposed on opposite sides of the plane of impact and whose mass concentrations are located substantially outwardly from the plane of impact respectively toward the heel and toe sections and also substantially spaced from the projection of the shaft axis in a rearward direction, said disposition of the shaft axis and the location of the mass concentrations being for use in causing the striking face, during the swing to be oriented generally normal to the line of swing and for use in providing for the head to have, at the moment of ball impact, a high moment of inertia with respect to the plane of impact so as to minimize twist of the striking face; and

said mass concentrations being substantially formed by a pair of weights in said head.
