Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 217 words
An adjustable golf club comprising in combination: a shaft having a rigidly-connected substantially right angularly disposed planar member attached thereto at one end, said planar member extending in at least two directions from the shaft; a head having a top surface forming a recess sized to receive said planar member with the top surfaces substantially coinciding with the same plane and align said shaft with the head for hitting a golf ball; a stub shaft rigidly fixed to the surface of the planar member opposite the shaft such that when the planar member is positioned to fit into the recess, said stub shaft extends substantially normal to said planar member at a position intermediate the planar member ends; said head including a well opening into said recess and positioned to receive said stub shaft when the planar member is seated in the recess; means to lock and spring-load said stub shaft in said well to spring-load said planar member in said recess; and said head having surfaces on two sides configured to strike the ball whereby by moving the head relative to said shaft to unseat the planar member from the recess, the head can be rotated one hundred eighty degrees and the planar member repositioned in the recess to allow hitting the ball with either surface.
Claim 2
Dependent Claim 217 words
An adjustable golf club comprising in combination: a shaft having a rigidly-connected substantially right angularly disposed planar member attached thereto at one end, said planar member extending in at least two directions from the shaft; a head having a top surface forming a recess sized to receive said planar member with the top surfaces substantially coinciding with the same plane and align said shaft with the head for hitting a golf ball; a stub shaft rigidly fixed to the surface of the planar member opposite the shaft such that when the planar member is positioned to fit into the recess, said stub shaft extends substantially normal to said planar member at a position intermediate the planar member ends; said head including a well opening into said recess and positioned to receive said stub shaft when the planar member is seated in the recess; means to lock and spring-load said stub shaft in said well to spring-load said planar member in said recess; and said head having surfaces on two sides configured to strike the ball whereby by moving the head relative to said shaft to unseat the planar member from the recess, the head can be rotated one hundred eighty degrees and the planar member repositioned in the recess to allow hitting the ball with either surface.
Claim 3
Dependent Claim 21 words
An adjustable golf club as defined in claim 1 wherein the hitting surfaces are positioned on opposite sides of the head.
Claim 4
Dependent Claim 23 words
An adjustable golf club as defined in claim 2 wherein said planar member is symmetrical about the elongated axis of the stub shaft.
Claim 5
Dependent Claim 41 words
An adjustable golf club as defined in claim 3 wherein said well includes a shoulder and said means to lock and spring-load said stub shaft in said well includes a spring positioned in compression between the shoulder and said stub shaft.
Claim 6
Dependent Claim 31 words
An adjustable golf club as defined in claim 1 wherein the planar member is wedge-shaped and the recess has a complementary configuration to maintain the shaft and head in tight engagement.
Claim 7
Dependent Claim 26 words
An adjustable golf club as defined in claim 4 including a sleeve fixed to said planar member and forming a center opening for receiving said shaft.
Claim 8
Dependent Claim 40 words
An adjustable golf club as defined in claim 5 wherein one head surface extends substantially perpendicular to the plane of said shaft for putting the golf ball and the other surface is positioned to provide lift on the hit ball.
