My invention relates to golf clubs, and hastween the sections, the parts being in partly for its object the providing of'novel means whereby the golf club may be taken apart for convenience in carrying the same, and whereby a single handle may be arranged to serve for a 'number of heads, and whereby for a given shaft.

It is the object of my invention to provide a golf club with a novel joint in the length of the club, to divide the club into sections which may be readily carried forginstance in l a suit case, and so constructed and arranged in novel manner that the sections may be quickly and conveniently assembled and disconnected.

A further object of my invention is to provide a tubular shaft for a club with fixed plugs and a rotatable collar provided with novel means to associate and dissociate the sections of the club.

My present invention is an improvement on the inventions shown, described and claimed in Lettersv Patent for improvement in golf clubs, issued to me January 4, 1927, as No. 1,613,360, and in my copending application for patent on improvements 'in golf clubs, filed in the United States Patent Oflice' December 6, 1926, as Serial No. 152,853. i

In golf clubs made in sections it is important that the joints be firmly locked together in non-rotative relation. I provide positive associating and dissociating means.

whereby the sections can be readily assembled or taken apart by a partial turn of the looking member.

The invention will be further readily understood from the following description and claims, and from the drawings, in which latter Fig. 4 is a side elevation of thesame,

partly broken away.

Fig. 5 is a side elevatlon of the same, partly broken away and partly in section for exposure of the interior of the connectlon beconnected relation.

Fig. 7 is a cross-section of the same, taken in the plane of the line 7-7' of Fig. 3; and, handles of different lengths may be provided Fig. 8 is a cross-section of the same, taken in the plane of the line 8-8 of Fig. 6.

I have shown my invention apfplied to a I club having -a tubular steel 'sha' 21 provlded with a head 22 and a handle 23. The shaft is divided at 24, forming an upper handle section 25 and a' lower head section 26. One of the sections, exemplified as the handle section 25, is-provided with.a plug 27 which is rigidly --secured therein, as bybrazing. The plug 27 has an extension 28,

which forms a tapered shank.

The other section of the shaft, shown as the head section '26, has a plug '29 fixed in 1ts upper end, .as by being brazed therein. This plug has a tapered bore 30, arranged to receive the tapered shank 28. a

The complemental walls of the taper shank and tapered bore may be provided with a relief portion or portions for aiding In their ready assembly and release. Thus the tapered shank is provided with a tapered portion 31, at the body of the plug, and a tapered outer end 32. Intermediate of the two ttaggered portions, the shank is undercut, as a sections to prevent relative turning between the sections so that the blow of the head upon the ball may not turn the head and may not result in torsional yield of the rod. Thus I provide a cross pin 37 positioned in the tapered shank28. The ends of the pin 37 are received in slots 38 in the upper end of the lower shaft-section for arresting relative rotation between the shaft-sections.

The slots 38 extend lengthwise of the shaftsections.

The pins are preferably spaced slightly from the bottom of the slots 38, and the proximate ends of the shaft-sections and the plu s therein are also preferably spaced slig tly' from each other when the sections are assembled, so as to permit the wedging action between the ta ered shank and its socket to have full e set.

A sleeve 41 is received about the proximate ends of theshaft-sections and hasoperative connection with. each of the shaft-sections, including bayonet slot, cam and pin connections for drawing the sections toward one another. The sleeve is exemplified as held in enolwise relation to the lower end of the handle section by means of a pin 42 fixed to the handle section. The sleeve is provided with a slot 43 in which'the pin 42 is received. This connection ermits the sleeve to be turned about the iandle section and retains the sleeve on said section to prevent loss of the sleeve.

The sleeve is also received about the upper end of the head-section and is provided with a bayonet slot 44. The head-section is provided with a pin 45 which coacts with the walls of the bayonet slot.

The bayonet slot has a mouth 46 opening in the lower edge of the sleeve. The bayonet slot comprises an entering portion 4:? which is substantially parallel with the axis of the sleeve, and alaterally extending cam portion a8, merging with the inner end of the entering portion 4-7. The incline of the walls of the cam slot at the entrance end of said slot is quite pronounced compared with the incline of the walls in the cam slot proper, so that an initial quick endwise movement between the tapered shank and the wall of its complemental bore is followed by a slower forceful endwise movement between said shank and wall of said bore to firmly wedge said shank in said bore with comparatively little turning force applied to the sleeve.

A cover, shown as a shell 51, is fined to the sleeve, as by brazing or shrinking the same thereon, and is received across the outer edges of the walls of the slots in said sleeve for hiding; said slots. It is also provided with knurled surfaces 52 for readily manually turning said sleeve. The shell is provided with an observation hole 58 registering with one end of the slot 43, so that the pin l2 in the slot 43 may be observed when it is located at that end of said slot.

"When the shaft-sections are to be assembled, the sleeve is rotated for positioning one end of the slot 43 against the pin 42, which also places the pin 42 in registry with the hole 53.

hen now the proximate ends of the shaft-sections are brought together, with the pin 45 of the head-section in the entering portion l7 of the bayonet slot, the pin 37 is located in the slots 38, for placing the shaft sections and the sleeve in non-rotative relation for ease of assembling the shaft sections in axial direction.

The shaft-sections are then pushed manually toward each other so that the pin 45 is placed in registry with the entering portion of the cam slot in the sleeve. Rotation of the sleeve is effected by manually turning the sleeve, by which movement the cam walls at the entrance end and in the body of the cam slot and the pin d5 act todraw the two shaft-sections toward each other for rigidly connecting the same.

The respective walls of the slot 43 and the respective Walls of the cam portion 48 coact with the pins on the respective shaft-sections for causing approach between said shaftscctions when said sleeve is rotated in one direction, and causing separation between said shaft-sections when said sleeve is rotated in the opposite direction, the latter separation being to sullicient extent so that, when the pin 45 reaches the low end of the cam slot, the'sha'ft-sections may be readily pulled apart manually for separating the same.

My improved construction provides ready and simple means for connecting and disconnecting the shaft-sections by a partial ro- I tation of one of the connecting parts, and the assembling and taking apart of the golf stick may be readily and quickly effected.

The incline of the cam faces at the entrance end of the cam slot is pronounced to cause quick coacting movement between the taper faces of the taper shank and the wall of its socket, and the incline of the cam faces in the cam slot proper is slight, to cause respectively, a firm wedging and ready release between said taper shank and the wall of its socket by slight turning force applied between the sleeve and the shanks.

It is of course obvious that changes may be made in the preferred form of my invention herein described without departing from the spirit of my invention embraced in the accompanying claims.

Having thus fully described my invention, what I claim as new, and desire to sccure by Letters Patent, is:
