2 Claims.

The invention relates to that type of golf club in which provision is made for torsional resiliency at a point between the head and the main body of a tubular metallic shaft.

In carrying out the invention the means by which torsional resiliency is obtained comprises a sleeve or tubular member formed separate from the head and its extension or hosel, and from the hollow metal shaft, and forming a connection between said parts.

The head and its extension or hosel may be made of the grade of metal usually employed in said parts, whereas the separately formed torsion member may be of a different grade of metal and tempered to such a degree as will serve the purpose of securing the desired resiliency.

The invention may be carried out in various forms, examples of which are disclosed in the accompanying drawings in which Figure 1 is a sectional view in part of the extension or hosel of a golf club with the improvement in one form embodied therein.

Fig. 2 is a transverse section on line 2--2 of Fig. 1.

Fig. 3 is a transverse section on line 3-3 of Fig. 1.

Fig. 4 is a view similar to Fig. 1 of a modified form of assembly with a readily detachable shaft.

Fig. 5 is a view of a further modification, the shaft being shown in section.

Fig. 6 is a view of a modified form of Fig. 5.

Referring to Fig. 1 the head of the golf club is shown at 6. This has an integral extension I, which in this assembly is in tubular form, substantially like the ordinary hosel. At the bottom of the hosel socket the extension is provided with a screw threaded seat or socket portion 8 to receive the screw threaded lower end of a metallic torsion sleeve 9, which has attached thereto at its upper end by a rivet or cross pin ill a hollow metallic shaft ll of substantially ordinary form and dimensions. The torsion sleeve 9 has a formation intermediate of its length to provide for torsional resiliency, and in the particular form shown, this torsional section of the sleeve is formed with lengthwise extending slots l2 in sufficient number to provide torsional resiliency between the head and the shaft when the ball is struck by the head of the club. This torsion sleeve is enclosed substantially by the wall of the hosel. It is slightly spaced therefrom, the clearance between this sleeve and the wall of the hosel being indicated at l3. This clearance extends from the screw threaded connection at the lower end of the torsion sleeve throughout the major portion of the hosel. At the upper end of the hosel there is provided a recess l4 formed by thinning the wall of the hosel on its interior, and in this recess a rubber tubular member i5 is located to provide resilient contact with '5 the upper end of the torsion sleeve. This rubber member rests upon the shoulder H at the bottom of the recess, and it projects inwardly slightly beyond the inner face of the wall of the hosel. so as to afford a yielding bearing for the 10 torsion sleeve at the upper portion thereof.

The shaft extends below the rivet l0 down to about the dotted line I 6, and this extension of the shaft is free from any connection with the torsion sleeve, so that relative movement circum- 1 ferentially can take place between the main body portion of the torsion sleeve and this extension of the shaft. In other words, torsional yielding of the sleeve can take place throughout the major portion thereof below the rivet H1 and 20 above the screw thread connection at 8, and this torsional resiliency can take place circumferentially in relation to the lower end of the shaft, which, as above indicated, lies within the torsional sleeve, and covers the slots therein.

This torsional sleeve can be made of highly tempered metal to get the desired resiliency, whereas the hosel may be formed of the usual character of metal. The torsion sleeve is made of thicker metal than the shaft. Should break- 30 age occur in the shaft or in the torsion sleeve, these parts can be removed and replaced with a new part or parts, and the head with its hosel will serve with the new assembly.

Referring to Fig. 4 this shows a torsion sleeve 35 9a within the hosel, and fixed at its lower end by a rivet or cross pin 81:. The hosel has a downwardly tapered bore, and the torsion sleeve is formed to correspond. The upper end of the torsion sleeve is screw threaded on its interior at Illa to receive the screw threaded lower end of the shaft indicated at Ila. In this assembly, should the shaft break, it may be unscrewed from the torsion sleeve and a new one inserted in its place. In this assembly also the torsion sleeve has clearance between itself and the wall of the hosel and there is a rubber cushion member, like in the form first described at I5a.

In the form shown in Fig. 5 the extension of 50 the head consists of a non-tubular or solid member 10: having a reduced portion at H which provides a shoulder at I8. This reduced extension I! receives the torsion sleeve 9:: on its exterior, the said tubular torsion member having its lower 56 lend abutting against the shoulder l8. rivet i9 is employed to fastenthe lower portion of the torsionsleeve to the reduced extension 11. The 1. hollow metal shaft indicated at Ila: is adapted to fitdown over the exterior of the torsion sleeve.

It is secured to said sleeve near the upper endor the latter by a .rivetlllzc. I'Ihe lower edge of the shaft rests upon the shoulder l8. Thistorof the head, and the tubularshaft respectively.

Inlthis'form also the tubular torsion'member is made separate from the head, and its'extension or shank, and can be of a difierent grade of metaL'and tempered for'the purpose of securing,
