union between'the parts in which the swingof the club and impact of club head with the ball will have a tightening rather than a loosening effect.

The inventionaalso aims to provide a connection of this character which will afford a slight amount of resiliency between the club head and shaft thereby compensating for the 2b rigidity of the steel shaft against torsional yield.

The invention also aims to provide a method and means by which the club head and shaft may be secured together in an extremely simple and economical manner.

With these and other. objects in view, the invention includes the novel method and means or construction hereinafter described and defined by' the appended claim. I

What I at present consider the referred embodiment of said invention is i ustrated in the accompanying drawing in which:

Fi ure 1 is a section through a club head and t e lower end of the shaft. Fig. 2 is a side elevation of the correspondmg the bore of the club head, and Fig. 3 is a sectional view of a modification.

Referring by reference characters to this drawing, thenumeral 1 designates the club;

head, here shown as of the wood- (driver, brassie or spoon type, having its hosel portion- .1 provid internal screw helical groove 1 thread which is formed preferably square in cross section, the bore bein preferably tapered as shown, with its sma est diameter at or adjacent the sole of the club.

2 designates the metal shaft which is customarily made of tapered steel tubing.

Upon this shaft, before it is inserted 1n the portion of the shaft before insertion in with a bore 1 having, an

bore of the club head, I permanently secure a sleeve 3 of resilientmaterial. Y

' I prefer to form the sleeve of-rubber and to permanently secure it to the-shaft by vulcanizing it thereon. The sleeve is bore and provided withan external screw thread (helical rib 3) to fit the thread or helical oove in the bore of theclub head. Thereafter, the shaft end is screwed into the bore until'the sleeve is firmly wedged theretape'red to correspond to the in, and compressed between the shaft and bore of the club head or hosel. v

' I form the threads in sucha direction that the swing of the club and impact of club head on the ball tends to rotate the head in ascrewon direction, and tighten rather than loosen .the joint. I i v The sleeve being resilient gives a slight torsional action which compensates for the objectionable rigidity of the steel shaft. I

In the form shownin Fig.3, the bore of the hosel 1 is shown asprovided with a helical rib 1 and the sleeve with a helical groove 3 to receive the rib, being a reversal of'the arran ement shown in Figs. 1 and 2.

aving thusdescribed my invention, what I claim is:

A golf club comprising a head having a bore" provided with a screw thread and shaft having a resilient rubber sleeve vulcanized thereon" having a'n exterior-screw threaded threaded bore.
