1. A golf putter head comprising;
- an elongated body portion having a substantially flat ball contacting surface and a rear surface, said rear surface including a central portion and a pair of lateral end portions on either side of said central portion, said rear surface being parallel to said ball contacting surface,at least one post fixedly attached to said rear surface portion and externally protruding outwardly in substantially normal relation to said rear surface in a direction pointed away from said ball contacting surface,an annular cylindrical hub for accommodating said post in axial relation thereto and rotatable to any predetermined position about said post;
means for securing said cylindrical hub at said predetermined position;
means for detachably securing a plurality of annular washers in external relation to said post for changing the location of the center of gravity of said putter head, wherein said annular washers are interchangeably interposed onto or detached from said post in accordance with a preselected pattern to change the location of the center of gravity of said putter head;
a shaft having a first and second end; and
means for securing said first end of said shaft to said hub in radial relation to said hub wherein said means for securing said cylindrical hub includes a female tapered portion and a male tapered portion, said female tapered portion engaging said male tapered portion.

Abstract
A golf putter having an adjustable head with at least one post extending therefrom. A plurality of annular washers are interchangeably secured to the post for changing the center of gravity of the putter head. A hub assembly attaches a shaft to the post. A novel hub locking mechanism locks the hub to the posts in which tapered male portion engages a tapered female portion. Also, a pin and groove arrangement prevents the shaft from rotating further than a predetermined angle from the vertical axis.
