Abstract
Abstract A golf club head is provided with sockets generally opposite the club face. The sockets receive removable and interchangeable weights fabricated from materials of varying density. Weighting changes can easily be effected by removing an existing set of weights and replacing them with a set made of greater or lesser density material. Preferably, the weights are screw-threaded into the sockets. A back side of the club head is hollowed in order to concentrate weight at the lowest possible point.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
118 words
A golf club head for attachment to a shaft comprising an integrally formed hosel, heel, toe, ball striking face and a lower flange extending rearward from said face a distance substantially greater than the thickness of the upper portion of said head, three internally threaded sockets extending rearwardly and horizontally along parallel axes along the lower portion of the club head adjacent said flange, and at least one set of removable and interchangeable threaded weights receivable in said three threaded sockets, the back of the club head opposite said face and above said flange being hollowed, and portions of said head between said sockets being hollowed, so that the center of gravity of the club head is lowered.
