Tl1is invention 1elateS t0 an improved comstruction of wooden shaft cles1gned more club slhaft eomposeclof 21'p1u1etlity 0f sec- 1:i0ns of clifferent ma"cerials laid side -by side theffiexibility of the sections of one ma't9rial material b ing positi0ned*oi1 the front Ceiiter' front cent0i"line 0f the shaft so as to render tion.

With th'es'e a'nd ot-her objects in' view, the

in-Ve1'1tion co nsists 0f certain 110v61 featuiez of 'c'onstr'uefii0n, as will be 'rnore fully deseiibed, jaild. partiularhfpbinted out in the a1iipaflded *0latims.

In the accompanying d'r2m'vving's: "Figre'l is a Perspe0tiVe viev'v 'of;a golf club having a shaftof my;jmprovecl 0011- struction and sh0wing the -strip 0f softer material positioned 'along the fr0nt center line of the shaft. 1

Figure 2 is a top view looking at the end 015 the shaft ancl showing the hickory section as shaded and in'line with the central axis through the head.

Figure 3 is a perspective view of a portion of one of the bamboo sections of the shaft. V

Figure 4 is a perspective view 0f a portion of the hickory section 0:E the shaft.

It is f0unol in thebuilding of a, sectional golf shaft desirable to provide sonne means by which itsflexibility may be nicely deter mined and eontrolled within certain limits so that ehe desirecl stiffness of the different more whippy 01 flexible than others; and it is found by expert-s in handling shafts of tl1is character that where a shaft is built up entirely of bamboo strips, it is t00 stiff for themajority '0f players anc'l that it' requires one 01 more strips or sections 01 a softer material t0 give lhe required f eel t0 tl1e Club t0 satisfy=the re'cwireine1its. --In s'oitie stan0es, 'it is fountl =tha t jstth e deSited amount of flexibility is' built ihto aj s-hzt'ftif all of the sections are made of ba'1'nbod'with ar'nountfof flexibility may befbu'ilt into 1i-l10.

s'h2ift: With refe'rence to the dfawings, 10 designates the shsyft 01 a golf cl i1b hzWifig ahead 11 Which may be of woodior metal;as;is des1recl, the bod7 of tliesliftlpoftibn being much m0re limber or flexible than bamboo.

In orcler to vary the stiflness of the 0111b,

it is found of adVanfag6 to plaee a Single strip or section of hickory .along the front center lin e 17 0f the shaft, as illustrated,

which gives a little m0re feel t0 the club than as though allthe sectionswere made of ba1nboo, that is, if all of the sections were macle of bamboo the shaft W0u1d be too stiif for the majority of players but by inserting a single section 0f hickory the sliaft is ren- .dered a little more flexible 0r just enough to give the desired Whip to the club for most layers. If the shaft is too flexible 0x whippy the hed in coming clown 011 a driving stroke Springs backward and Will give a slice t0 tl1e ball, While il:' the shaft is toostifl it lacks clriving p0werancl, the ball is not driven so far as when the shaft possesses 90 bereut strength and flexibility and. which is exactly the proper Wlfip o1 flexibility. By 2. A shaft for golf clubs comprising a plurality 0f' sec'tions of bamboo anal a Single placing this more flexible section of hickory on tl1e front center line of the Club, I 0bcain tl1e flexibilitiy 01 whippy efiect in that clirectin leaving the stiffer 01 less flexible sections 011 the sides t0 reslst the driving impact of the Club With the ball, tl1us re- From tl1e foregoing it Will be seen tl1at I have provided nov elmiaans for permitting a certain amount 0f flexibility or whip in tl1e golf club shaft in the fo1ward direction and at the same time have preservecl the necessary stifl'ness of the shaft in the other direction 110 assist in resisting the =driving impact on the ball.

The foregoing description is clireccedv solely towarcls the construction illustrated,
