Abstract
Abstract The training and practice golf club of the present invention is directed to the attainment of the proper feel of the grip for a golf swing or stroke, other than on a putting surface. This feel is obtained by dividing the club''s normal grip means transversely into two parts. The upper portion is immovably secured to the upper end of the shaft in the usual manner. The lower portion of the grip means is secured to a fitted and freely rotating sleeve which is slipped over the club shaft and moved upwardly until the two grip portions abutt. A portion of the sleeve extends beyond and below the terminus of the lower grip means. A coiled spring is slipped over the sleeve portion and spaced from, but adjacent to, the terminus of the lower grip means. One end of the coiled spring is bent inwardly at right angles and restrained in a hole bored in the sleeve just below the lower grip means. The projecting end of the spring rides in a transverse slot to provide limited rotation. The lower end of the spring is also bent inwardly at right angles and rides in a registering transverse slot in the sleeve and its projecting end is restrained in a hole bored in the main shaft. In this manner the lower portion of the grip means may be rotated against the tension of the coil spring to provide the feel in properly gripping a golf club. Unless the tension by rotation is felt, the proper grip is not attained.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
142 words
In a golf practice club, in combination a shaft, a grip for said shaft, said grip being of standard length divided transversely into two portions upper and lower, the upper portion being immovably secured to the upper end of said shaft, a sleeve closely but rotatably encircling said shaft from the lower end of the secured upper grip portion to well below the lower end of the normal grip length, the lower portion of said grip being secured to the upper end of said sleeve abutting the upper grip portion, resistant spring means spaced from the lower end of said sleeve and from the lower end of the lower grip portion, said spring being secured at one end by the said shaft and at the other by the said sleeve for rotation of said sleeve against the resistance of said spring means.
Claim 2
Dependent Claim
142 words
In a golf practice club, in combination a shaft, a grip for said shaft, said grip being of standard length divided transversely into two portions upper and lower, the upper portion being immovably secured to the upper end of said shaft, a sleeve closely but rotatably encircling said shaft from the lower end of the secured upper grip portion to well below the lower end of the normal grip length, the lower portion of said grip being secured to the upper end of said sleeve abutting the upper grip portion, resistant spring means spaced from the lower end of said sleeve and from the lower end of the lower grip portion, said spring being secured at one end by the said shaft and at the other by the said sleeve for rotation of said sleeve against the resistance of said spring means.
Claim 3
Dependent Claim
44 words
The combination of claim 1 wherein the grip portions are substantially equal one portion being for the right hand and the other for the left hand, and wherein the resistance of the spring means produces the physical response required of a proper golf stroke.
Claim 4
Dependent Claim
75 words
The combination of claim 1 wherein bearing washers are inserted between the two grip portions and where the resistant spring means is a coil spring surrounding the sleeve with one end secured in a hole in the sleeve and passing through an elongated slot in the shaft for limited rotary movement and the other end is secured in a hole in the shaft after passing through an elongated slot for the same limited rotary movement.
Claim 5
Dependent Claim
63 words
The combination of claim 1 wherein alternate cooperating holes and slots are provided in the said shaft and sleeve, a pair of abutting cylindrical plugs each having means for receiving studs, a pair of studs, one each secured in said abutting cylinders through the respective registering openings in the sleeve and in the shaft, and the resistant spring means secured between said studs.
Claim 6
Dependent Claim
166 words
A golf practice club having the conventional shaft, a grip of customary length for said shaft, said grip being divided into two separate upper and lower parts, the upper part being secured to the upper end of the shaft in the customary manner, an external sleeve surrounding said shaft for rotation thereabout with minimum clearance, said sleeve extending from the lower end of upper grip part to well beyond the lower end of the lower grip part, said lower grip part secured to the upper end of said sleeve so that the lower end of the upper grip part and the upper end of the lower grip part abutt and bear one against the other, resistance means spaced from the lower grip part secured at one end of the shaft and to the sleeve at the other end so that the counter-clockwise rotation of the lower grip portion and sleeve against the resistance will produce the appropriate feel for the proper grip for a Golf stroke.
Claim 7
Dependent Claim
166 words
A golf practice club having the conventional shaft, a grip of customary length for said shaft, said grip being divided into two separate upper and lower parts, the upper part being secured to the upper end of the shaft in the customary manner, an external sleeve surrounding said shaft for rotation thereabout with minimum clearance, said sleeve extending from the lower end of upper grip part to well beyond the lower end of the lower grip part, said lower grip part secured to the upper end of said sleeve so that the lower end of the upper grip part and the upper end of the lower grip part abutt and bear one against the other, resistance means spaced from the lower grip part secured at one end of the shaft and to the sleeve at the other end so that the counter-clockwise rotation of the lower grip portion and sleeve against the resistance will produce the appropriate feel for the proper grip for a Golf stroke.
Claim 8
Dependent Claim
29 words
The golf practice club of claim 5 wherein bearing washers are inserted between the abutting grip parts and the resilient spring means is a coil spring surrounding the sleeve.
Claim 9
Dependent Claim
40 words
The golf practice club of claim 5 wherein the resistance means is a spring retained in position by spaced studs, said studs being retained in precise spaced relation by two abutting cylinders within the shaft in which they are secured.
