GOLF CLUB Filed Oct. 8, 1928 gn/uente@ Patented" Mar. 22, 1932 jf Y HERBERT CfLAGERBLAnncFj BRrsTon, cOnlineTrotter,l AssrGNoR. VTo THE;.Hoiarc'air 'f MANUFACTURINGnsolarium,"orgisRIsToL,V CONNECTICUT; A CORPORATION; or CON-v NEGTICUT i GOLF :CLUB L j Application inea octobvef s, u192s. k.smal No. 311,201.:l

This inventionrelates tok improvements in.

y golfl clubs and particularlyto a ynovel method Vof attaching handle shafts lto 'the clubhead and` a novel form of ,such` connection'. The

4invention Vis particularly adapted for usein attaching golf club shafts of metallic tubular type-to metallic golfclub heads.

In the presentV form of*V attachment :y anadapter is utilized, such adapters being now quite common in fthe art. Described generally, they-consist of a tubular sleeve that-projects partly Without the hosel of the club head and partly WithinV 'saidrhosel, .the adapter surrounding the'handle shaftgand insuring :a neat .lit ofthe shaft to the hosel. Onefea-V ture of the present invention is a formofconnection betweenV the handle shaft and `the clubhead wherein the means yfor attaching the shaftV to thehead does not engage the adapter.

Another feature of the, presentinvention isthe formation ofsecuring means forat- `taching the adapter in the clubhead integral`y ly WithL said adapter. Inother Words, the

adapter has integrally formedmeansfor se-k curing itin the club head, and the securing meansrfor attaching the shaft proper are Y. spaced from or independent Vof saidfadapter so that no fastening meansof anynature project .through'theadapten 10; l

Another [object contemplated bythe present invention is the formationfof the adapter in situ in. the hosel Vof the club head.

LMore specifically,the invention consists in forming in the hosel of the club headl an axial bore Whose inner portion is of reduced diam- Y eter conforming to the diameter kof thev shaft B attached to said head! In thewall of said 1 hosel near kthe outer end of saidaxi'al bore there is formed aseriesfof recesses and in applying the shaft to the head a mandrelyor This is important because, that A Where the fastening means, usually a rivet forattaching theV shaft in the headl extends through the adapter aswvellwas the. shaft, it

the. like, Whose cross-section iisthe. sameas that: ofv7 theshaft to be installed, is'inserted Yin the axial bore, being received inthat. pori v`tionof the bore of minor-diameter.V A plastic ed forthe same. The handle ris then A secured i in place by meansof the usualxrivet extending through the hosel Vand that Iportion of the shaft Whichextends beyond the inner ex-.

Fig. 2 is a sectional view of the clubhead v f hosel, as it is originally'.y formed; j F ig. S'is a similarv view-With the mandrel inserted in the hosel and4 the adapter molded .L

around the same; n

` Fig. 4 is a similar view but With the handle shaft substituted for the mandrel and,` at-r tachedto the club headby the usual rivet;

Fig. 5 isa cross-sectional view `on the line 5-5of Fig. 4, more clearly illustrating `the fr f means of securing theadapter in the hosel;v

Fig.k 6 is adetail Vviewshovving themodif inthe hosel.- Y p. p p In accordancewithv the present invention thehosehlO of the club lheadis formed fwith lied. form of means forsecuring the adapter an axlebore having-'a portion ll of reduced 1 'i diameter ,and a portion 12 of enlarged diam:

, Y miV is Withdrawn and the handle shaft substitut-'9 j ftremity of the adapter into that portion of*y soAAI eter near the extremity of ysaid hosel. At y the extremityof 'said hosel, and preferably; at.l Points Vspaced ycircumfere'ntially Vthereof, Y j

the-relis va-.serie's of recesses orapertures y13. c ,y Inthe finished clublthetubular metallic shaft, 10.6

14 whose end portion conforms to the diameter of the reduced portion 11 of the axle 12 of said axial bore and for some distance e along the shaft beyond the end of the hosel.

This adapter is formed in situ of a plastic nonmetallic material, 'such as celluloid, pyroline, 'bakelite, etc., and during the formation of the same in situ in the club head h0sel,.a portion of such material flows into the rrecesses 13, forming interlocking projections 16 on said adapter. For securing the shaft itself into the club head hosel there is a rivet 17 extending through the hoseland the end of said shaft projecting beyond the inner extremity of the adapter. 'In this kWay an adapter ofmaximum strength is provided The rivet 17 is spaced from the adapter instead of extendingr therethrough and by forming the interlocking projection 16 integrally with the adapter it is unnecessary to utilize fastening means of any nature Whatever that might tend to cause a splitting of the adapter. Furthermore, an absolutely close fit of the adapter, both with respect to the exterior surface of the shaft and the interior surfaceof the hosel, is insured by molding the adapter Iin situ in forming the connection. e In lieu of the axially extending recesses 13 spaced circumferentially of the hosel an arrangement such as 'shown in Fig. 6 may be utilized.' In this form of interlocking connection between adapter and hosel the end of the hosel is formed with longitudinally extending recesses 13a such as are used in making a dove-tailed joint. These recesses, in

' both forms of the invention, may extend the full` thickness of the Wall of the hosel alv though this is not absolutely essential.

plying the handle shaft to the club head after it has been formed as shown in Fig. .2 with the axial bore of two different diameters, a mandrel 18k is inserted all the Way into the hosel and a retainer 19 placed around the portion of the shaft adjacent the extremity of the hosel. 'The plastic material constituting the adapter is then molded, being deposited in the space between the mandrel and portion 12 Aof the enlargeddiameter of the hosel, a suicient quantity of this material being used to completely fill such space and retainer 19 as well asy the recesses 13 or 13a. After the adapter has been thus formed, the mandrel 18 and the retainer 19 are removed and the han- =dle shaft, that is to be used in the club, subportion of the adapter projecting beyond the osel is cut away or reduced to a taper-like crosssection, tapering away from the end of the hosel to a comparatively tine ed e at its upper extremity. This gives the clu a very neat appearance. f

As' at present contemplated, it is proposed to introduce the material constituting the adapter into retainer 19 and then place it under pressure to force the same over into hosel 10 and around mandrel 18. For convenience the retainer may be made in sections to facilitate its removal and if desired its cross-sectional configuration may conform to that desired for the finished adapter, thereby eliminating the trimming down of the adapter as a finishing step. While non-metallicmaterials are believed preferable for the adapter, metals, such as aluminium. may be used if desired. One feature of non-metallic materials is that different colored adapter can be made, thereby giving the finished club a rather pleasing appearance.

lVhat I claim is:

1. The hereindescribed method of applying handle shafts to golf club heads which consists in forming an axial bore in t-he hosel of said head and recesses inthe Wall of said bore, inserting a mandrel in said bore, molding an adapter in said bore and recesses with the mandrel therein, substituting the handle shaft for said mandrel after said adapter has been formed, and'finally securing said shaft 1 in said'hosel.

2. The method of applying handle shafts to golf club heads which consists in forming an axial bore in the hosel of said head, inserting a mandrel in said bore, molding an adapter in said bore with the mandrel there-v in, substituting the handle shaft for said mandrel after said adapter has been formed, and

securing said adapter in said bore and saidy shaft-in said hosel beyond the inner end of said adapter.
