Abstract
Abstract A golf club head incorporating a hollow interior with a movable weight supported on a mounting rod which can be oriented in different angular positions to counteract the tendency of a golfer to hook or slice the ball and to increase the distance which the ball is driven due to the additional forces exerted on the ball by the movable weight. The movable weight is centered on the mounting rod by spring devices and the overall shape and configuration of the golf club head is not changed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
139 words
A golf club head comprising a body having a substantially flat golf ball impact surface on the leading surface thereof, a bore in said body having a longitudinal axis extending from said impact surface area to the rear of the club head, a mounting rod disposed in said bore generally along said axis, a weight means mounting said weight on said rod for slidable movement in response to the swing of the golf club, and means for adjustably supporting the mounting rod in said bore so that the longitudinal axis thereof may be angularly varied in relation to the longitudinal axis of the bore so that movement of the golf club head in a path to cause the golf ball to deviate from a straight line flight path will be compensated for by the shifting of the movable weight.
Claim 2
Dependent Claim
139 words
A golf club head comprising a body having a substantially flat golf ball impact surface on the leading surface thereof, a bore in said body having a longitudinal axis extending from said impact surface area to the rear of the club head, a mounting rod disposed in said bore generally along said axis, a weight means mounting said weight on said rod for slidable movement in response to the swing of the golf club, and means for adjustably supporting the mounting rod in said bore so that the longitudinal axis thereof may be angularly varied in relation to the longitudinal axis of the bore so that movement of the golf club head in a path to cause the golf ball to deviate from a straight line flight path will be compensated for by the shifting of the movable weight.
Claim 3
Dependent Claim
55 words
The structure as defined in claim 1 wherein said means mounting the rod includes opposed recesses in the opposite ends of said bore, one end of said bore having a plurality of spaced recesses for selectively receiving the end of a mounting rod to orient the rod in a selected angular relation to the bore.
Claim 4
Dependent Claim
111 words
The structure as defined in claim 2 wherein the plurality of recesses are oriented in the rear of said bore, an insert plate mounted on the rear of the club body and forming a closure for the rear end of the bore, said insert plate having a projecting boss extending into the bore and provided with a concave inwardly facing surface, said recesses being disposed in said concave surfaces and being horizontally disposed for enabling the mounting rod to be disposed in different angular positions in a horizontal plane to counteract the out-to-in swing which causes a slice and the in-to-out swing which causes a hook of a driven golf ball.
Claim 5
Dependent Claim
54 words
The structure as defined in claim 3 wherein said golf ball impact face includes an insert plate forming a closure for the forward end of the bore, said insert plate including a boss on the inner surface thereof extending into the bore and including a recess receiving the forward end of the mounting rod.
Claim 6
Dependent Claim
24 words
The structure as defined in claim 4 wherein said mounting rod includes a reduced end at each end thereof for reception in the recesses.
Claim 7
Dependent Claim
59 words
The structure as defined in claim 5 wherein said bore, mounting rod and weight are of cylindrical construction, and a coil spring interposed between each side of the weight and the insert plates to retain the weight in resiliently spaced relationship to the plates to enable movement of the weight during acceleration and deceleration of the golf club head.
