Golf putter system
First Claim
1. A golf putter, comprising:
- an elongated, generally tubular head having a striking surface, a toe end and a heel end;
a shaft fixed to the head;
the head having an elongated bore connecting the heel end to the toe end, the bore being substantially, continuously threaded from the heel end to the toe end;
a first pair of threaded plugs, each of said plugs being threadably movable along substantially the full length of the threaded bore;
a selected number of similarly-shaped, discshaped weights disposed between the first pair of threaded plugs;
a compressible spacer disposed between the pair of plugs to prevent relative motion between the weights, plugs and the head;
whereby the first pair of plugs, spacer and weights may be moved to a selected position along the length of the bore in the head to adjust the location and balance of the putter'"'"'s sweet spot.

Abstract
A golf club head, particularly a putter, having an improved selectable weight and adjustable balance system. The head has an elongated threaded weight chamber extending from toe to heel. The chamber contains weights, preferably coins, and thrust/ friction washers which are captured and secured by opposing threaded end plugs. The amount of weights used and their collective effective center of gravity is adjustable by the user. The center of gravity or sweet spot is adjusted when the end plugs along with the captive weights and washers are rotated toward the toe or heel. When rotated toward each other, the end plugs produce a strong locking force on the entire weight assembly. The balance and sweet spot characteristics are also controlled by the strategic placement of weights within the chamber. The washers can also be used as spacers to aid weight distribution. When more weight separation is required, an optional compression spring is used between weights. By selecting the amount of weights deployed and by the strategic placement of the weights, many options of putter head weight and balance are available to the golfer.

12. A golf putter, comprising:
-
an elongated, generally tubular head having a striking surface, a toe end and a heel end; a shaft fixed to the head; the head having an elongated bore connecting the heel end to the toe end; a pair of compression discs in said bore; a pair of snap rings mounted at opposite ends of the bore; a selected number of similarly-shaped, disc-shaped weights disposed in spaced weight groups between the snap rings; and a compression spring being disposed to separate the weight groups and to prevent relative motion between the weights, snap rings, and the head.
