Abstract
The golf club head with an adjustable center of mass provides for player adjustment of club action according to the position of an adjustable weight or mass within the club head. A hollow, “metal wood” type club head includes an open receptacle in the sole wall, with an L-shaped arm and mass installing in the receptacle. The arm includes a club head attachment end that attaches within the receptacle, and a weighted end, which extends into the interior of the club head. The L-shaped arm may be turned about its mounting axis to orient the weight or mass to the front, rear, left, or right within the club head, or to some intermediate position therebetween. The adjustably positionable mass alters the collective center of gravity of the assembly to affect the draw, fade, and loft tendencies of the club, as well as affecting the vibratory characteristics of the club.
