ADJUSTABLE GOLF CLUB.

Application filed. March 8, 1926. Serial No. 93,066.

club may be employed to accomplish the several drives that ordinarily require the use of a series of clubs of different character.

Another object is to provide a means for eflectin an interlocking connection between the golf club and an arbor on which it is supported which will admit of the head being disposed in various fixed positions circumferentially of the arbor and whereby the head and arbor will be so securely interengaged as to inhibit accidental displace ment of the head relatively to the arbor under the action of the forces to which the head is ordinarily subjected in making drives.

Another object is to provide a mounting for an adjustable golf club head which is simple in construction and which may be easily and quickly operated in making adjustments of the head, and which is so formed as to permit ready assemblage and demounting of the parts.

With the foregoing objects in view, together with such other objects and advantages as may subsequently appear, the invention resides generally in forming a golf club shank with an expansible arbor on which the golf club is turnaloly mounted, and in providing a means for expanding the arbor into interlocking engagement with golf head, and further resides in forming the expansible arbor and a sleeve on the head with interengageable teeth so formed and arranged as to effect interlocking engagement on expansion of the arbor and operable to inhibit turning movement of head rela tively to the arbor.

The invention further resides in the parts and in the combination, construction and arrangement of parts hereinafter described and claimed and illustrated by way of example in the accompanying drawings, in which 1 Fig. 1 is a club;

Fig. 2 is a view in side elevation with porperspective view of the golf and is formed with a series tions broken away of the expandible arbor;

Fig. 13 is a detail in section as seen on the line 13-13 of Fig. 11; v

Referring to the drawings more specifically, 15 indicate the golf club shank fitted with the usual shaft 16 which shankis formed with an expandible arbor 17, the axis ofwhich projects obliquely in relation to the shank 15. The arbor 17 is tubular of longitudinally extending slots 18, here shown as four in nd elevation of a two:

number whereby the arbor is divided into four members a, Z), 0 and cl, as shown in Fig. 3. Theinner margins of the'outer ends of the members a, b, 0 and (Z are beveled as indicated at e in Fig. 2 and formed on the outer periphery of these members are longitudinally flat faces 9 extending substantially on radial planes leading from the axis of the arbor and. having inclined flat faces h extending extending ratchet teeth f having obliquely in relation to the front faces 05. i i The inner end portion of the arbor tapers inwardly to its intersection with an annular shoulder or flange 19 forming a wedge seat for a divided nut 20, shown in Figs. 4 and 5; the nut being formed with an internal a removable pin or key 23 as shown inFig.

11 whereby the nut 20 may be held against rotation on the arbor in effecting assemblage and adjustment of the golf headon the arbor. "as will presently: be fclescribedi.

The sleeve formed with an end wall 34; having an ope'ni'iig 35Yadapted to receive the stem 29" onthe'expander 2$and is formed with a transverse opening 36 l for the reception 'of a 'r'o'c l r shaft 37 formed on a-handle' 38. The rock ,shaft formedwith a reduced intermecliateportionconstituting cam 39 arranged to operatively abut against the outer end of the stem 29 on the expander; the red ced can portionof the rock, shaft being i of length 3 substantially corresponding to'the diameter of the stem 29], so "as to provide spaced shoulders a0 and 41, between 'whichfihe stem 29, extends to holdfthe rock shaft against longitudinal movement in ,the opening 36. The handle; 38, is formed" on the rockj shaft 37 so that it nay be positioned in a longitudinal recess 42 formed on "the side of tlie sleeve 31 with ,thehandle 38 extending alongside, of the sleeve 31 when the cam 39 is disposed to move'the expander 243w its ad e ct'pesit o Inf assembling the head on the arbor 17 the expjander jis first positioned within the arbor with its inner end portion 26 seating in the socket 2T whereupon the divided nut 20 is seated on the tapered inner end portion of thej'arbor with, the nut 21engaging the demountable' pin 23'. Paper shims areinterposedbetween the contiguous faces of the halves of the nut20. The sleeve 31. is then advanced over the outer eiid of the arbor with the rock shaftB'Z. disposed inthe opening 36, and positioned so that the low face 13 of thecam' fiawill be arranged opposite the opening 25, whereupon the sleeye is screwedinto engagement with the divided nut by rotating the'head around the arbor which causes the sleeve to advance relatively to the arbor with the stem29 on the expand- 31 so th at the sleeye may berota ted 'elative- 75 ly to the arbor to position the teeth 33 op po site the teeth When the head has thus been advanced to thedesired position longitudinallyof the arbor and turned to the desired;

position axially thereof, the rockshaft37-is 3 turned through the medium of the I handle 38 to cause the cam to thrust the expander 24;; inwardly and cause the tapered head 28. thereof to effect wedge engagement withthe d of the arbor and thereby expand the latter so as to force theteeth f thereon into interlocking engagementwith the. teeth 33 on the sleeve 31, as shownin Figs- 12rand .14.,

The ca n89 will thenbe disposed as shown in Fig. 18 and {the handle 38ivill-be posi tioned inthe reccssA-2asshown in Figs. 1

and 11. The longitudinalthrusts imposed I. on the sleeve ,31 by the cam bearing against desired adjustment of the head on the arbor the pin23 may be removed Whenthe head. and arbor are thus interengaged, the radial faces ofthe teeth f i will ,abut against corresponding faces on ripheral faces of the arbor and sleev, there'- by effectively inhibiting rotation of the'he'a d' onthe arbor. lVhen it is'desired to readjust the head on inwardly, thereby forcing the expanderbut wardly, thus freeing the headso that I be turned to any desired position axi'ally'of the arbor.

In effecting this may be rotated around the arbor without unscrewing it from the nut eogas steamer-,1;

When not engaged by'the' pin eaisnee as,

turn on the arbor. The head is theri re-engaged with the arbor by manipulating,'theligg,

The nut 20 is designed so as to afford a clearance. between it and the shoulder or flange 19, which permits the sleeve 31 helIigij lgu outer end portions of the members a, b, 0 and the teeth 33 throughout the contiguous pe'- the arbor, the rock :shaft 37,- with'tlie'c'am 39111 bers a, b, a and cl of the arborwillbe'movepl adjustment, the sleeve L advanced longitudinally relatively to the arbor when the cam 39 is positioned to free the expander so as to permit adjustment of the spacing of the axis of the rock shaft 37 relative to the end of the arbor in disposing the cam in proper operative relation to the expander, so that when the lever 38 is disposed alongside of the sleeve 31 the cam 39 will dispose the expander in proper position to cause the teeth on the arbor and sleeve to be tightly interengaged.

I claim:

1. In an adjustable golf club, a shank, an expa-nsible arbor thereon, a head carried by said arbor and turnable thereon, an expander for said arbor, and means for operating said expander for effecting interlocking en-- gagement between said head and arbor.

4. In a golf club, an expandible arbor, a longitudinally movable expander in said arbor, a head carried by said arbor, interengageable teeth on said arbor and head,

and a cam carried by said head operable to actuate said expander to effect engagement of said teeth.

5. In a golf club, an expandible arbor, having a tapered inner end portion, an externally threaded nut seating on the tapered portion of the arbor, a head including a sleeve encompassing said arbor andhaving screw engagement with said nut, means for expanding said arbor, and means operable on expansion of said arbor to effect interlocking engagement between the head and arbor.

6. In a golf club, a tubular arbor formed with a plurality of longitudinally extending slots and having a toothed outer periphery, a head including a sleeve encompassing the arbor and having teeth on its inner periphery, an expander arranged for longitudinal movement in relation to said arbor, and a cam for effecting operation of said expander to cause interengagement of the teeth on the arbor and sleeve.

7. In an adjustable golf club, a shank, an expansible arbor thereon, a head carried by said arbor and turnable thereon, an expander for said arbor, and means for operating said expander for effecting non-rotational relation between said head and arbor.

In testimony whereof, I have aflixed my signature.
