Abstract
Abstract An elongated shaft is provided of a length substantially equal to the length of a driver golf club and one end of the shaft is provided with a hand-grip similar to those provided on golf clubs. The other end of the shaft has an enlarged abutment thereon spaced from the terminal end thereof and a weight member is provided having a bore formed therethrough of a size to snugly receive the terminal end portion of the shaft remote from the handgrip therethrough with the weight member slidable on the shaft, but lightly frictionally held in position thereon. The weight is preferably constructed of shape retentive rubber or plastic and the entire combination consisting of the shaft, the weight member and the abutment member is of a total weight and balance equivalent to the weight and balance of a driver golf club.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
179 words
A straight elongated shaft having a handgrip on one first end portion thereof, the second end portion of said shaft being cylindrical, tapering toward the terminal end thereof and free of enlargements throughout at least a predetermined length thereof, a generally spherical weight member having a substantially constant diameter cylindrical passage formed therethrough on a diameter of said weight member and of a size to snugly receive said tapering second end portion therethrough with a larger diameter portion of said tapered second end portion lightly frictionally seated in the end of said passage remote from the terminal end of said second end portion, the length, weight and lengthwise balance of said shaft, with said weight member thereon, closely approximating the length, weight and lengthwise balance of a conventional golf driving club, said weight member being lightly frictionally retained in position on said tapered second end portion at a point spaced a predetermined distance from the terminal end thereof, but being freely slidable thereon upon slight shifting of said weight member toward the terminal end of said second end portion.
Claim 2
Dependent Claim
179 words
A straight elongated shaft having a handgrip on one first end portion thereof, the second end portion of said shaft being cylindrical, tapering toward the terminal end thereof and free of enlargements throughout at least a predetermined length thereof, a generally spherical weight member having a substantially constant diameter cylindrical passage formed therethrough on a diameter of said weight member and of a size to snugly receive said tapering second end portion therethrough with a larger diameter portion of said tapered second end portion lightly frictionally seated in the end of said passage remote from the terminal end of said second end portion, the length, weight and lengthwise balance of said shaft, with said weight member thereon, closely approximating the length, weight and lengthwise balance of a conventional golf driving club, said weight member being lightly frictionally retained in position on said tapered second end portion at a point spaced a predetermined distance from the terminal end thereof, but being freely slidable thereon upon slight shifting of said weight member toward the terminal end of said second end portion.
Claim 3
Dependent Claim
22 words
