Abstract
Abstract A golf club has a head which may be selectively swingweighted by the club owner to any swingweight he may desire. The base of the head is configured to define heel and toe portions at opposite ends and rearwardly of its ball-striking-face. The heel and toe portions are enlargements in each of which a weight-receiving bore is provided, each bore extending inwardly from the outboard end face of the respective heel or toe portion. A cylinder is extendable into each bore and held therein by means of a threaded engagement therewith. A selected number of swingweights and a packaging member are receivable in each cylinder.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
215 words
In a perimeter-weighted putter consisting of a shaft and a head interconnected by a hosel, the improvement in means for controlling the ultimate degree of perimeter weighting of the head, the head comprising: a foot having a lower face shaped with a convex curve, a ball-striking member extending upwardly from and integral with the foot and presenting a forwardly-facing vertically-disposed striking-face, a pair of spaced-apart side portions extending rearwardly from the ball-striking member and defining respectively a heel and a toe extending inwardly from the respective outboard end face of the side portion and defining a hollow space therebetween and rearwardly of the striking face, a pair of coaxially-aligned weight-receiving threaded cylindrical recesses each formed at the outboard end of one of the side portions and extending inwardly from the end faces of the toe and heel respectively, the shaft center line being extendable from the shaft intermediate said heel and toe thereof and with the shaft center line being offset forwardly of the vertical plane of the striking face, a pair of threaded capsules each receivable in and in threaded engagement with a respective recess, and a plurality of quantifiable incrementally-weighted discs variably receivable in each of the capsules facilitating a weight distribution in the head according to the desire of the individual user.

Claim 3
Dependent Claim
196 words
In a perimeter-weighted putter consisting of a shaft and a head interconnected by a hosel, the improvement in means for controlling the perimeter weighting of the head, the head comprising: a ball-striking member presenting a forwardly-facing vertically-disposed striking-face, a pair of spaced-apart side portions integral with and extending rearwardly from the ball-striking member and defining respectively a heel and a toe extending inwardly from the respective outboard end face of the side portion and defining a hollow cavity therebetween and rearwardly of the striking face, a pair of coaxially-aligned weight-receiving threaded recesses each formed at the outboard end of one of the side portions and extending inwardly from the end faces of the toe and heel respectively, the shaft center line being extendable from the shaft intermediate said heel and toe, a pair of threaded capsules each receivable in and in threaded engagement with a respective recess, a plurality of quantifiable incrementally-weighted discs variably receivable in each of the capsules facilitating a weight distribution in the head according to the desire of the individual user, and a compressible member receivable in each capsule for maintaining the weights in the respective capsule in a tight relationship therewithin.
