To all whom it may concern:

Be it known that l, Gannon W. Maureen, a citizen of the United States, residing at Dayton, in the county of ll lontgomery and State of (Ohio, have invented certain new and useful Improvements in Methods of At-- taching Handle-Shafts to Golf-Clubs and like Articles, of which the following is a specification.

My invention relates to golf clubs and more particularly to the means and mode for securely attaching the extremity or tenon of the shah within the socket, or as com monly known golf parlance, the hosel of the head. a

The object of the invention is to adord an easy, convenient and eficient manner of attaching the shaft within thev hosel whereby it will not only tend to resist withdrawal, but will also moreefi'ectively resist the tor-'- sional strain to which the connection is subjected and so prevent the loosening ofthe shaft connection within the socket or hosel.

A further result of the proved construction is to afiord a better balanced head by the removal of stock and weight from the socket or hosel lea an increased preponderance of weight in the head where it 18 more desirable and effective and results in a better balanced club. a a With the above primary and other incidental objects in view as will more fully appear in the specification, the invention consists of the features of construction, the

hereinafter described and set forth in the claims.

. section through the socket or hosel with the Referring to the drawings, Figure 1 is a perspective view of the assembled golf club embodying the invention forming the subject matter hereof. Fig. 2' is a longitudmal end of the shaft seated therein, the view being somewhat enlarged and the relative shapes and contours somewhat exaggerated for the purpose of illustration. Fig. 3 is a transverse sectional view on line 3-3 of Fig. 2, the view being an enlargement and the outline somewhat exaggerated as in ii it.

l iike parts are indicated by similar characters of reference throughout the several views.

- upon the shaft itself which eventually rellt has long been the practice to accurately fit the tapered extremity of the golf club shaft into the correspondingly tapered socket or hosel and to secure the same in means of cement, reinforced by one or more transverse pins. It has been found in practice, however, after long periodsof severe use, that there is a tendency. for the shaft to loosen within the socket or hosel. This condition-sometimes arises in comparatively new clubs. Clubs are frequentl allowed to lie in the hot summer sun whlch tends to out and shrinkthe shaft as well as loosen and deteriorate the cement. This loosening tendency is of course materially increased by the torsional strain due forded by the laterally extending head under influence of the impact at the striking of the hall. It has been frequently found in the repairing of golf clubs that in those shafts fitted as has heretofore been customary, longitudinal cracks or splits are found in the shafts as indicated at A, Fig. l. lit is thought that this condition is primarily due to the looseness ofthe lit of the shaft within the hosel which at the impact of the head upon the ball permits the torsional strain to be received upon the transverse pins'hereinafter referred to by which the shaft is secured. This results in undue strain directly sults in a weakening or splitting of the shaft. To overcome this difliculty by providing a form of interlocking shaft and hosel whereby the transverse pins will be relieved of the torsional strain 1s one of the primary objects of the present invention.

Referring to the drawing, 1 is the shaft of the club upon which is fixedly carried the laterally extending head 2 attached by the engagement of the shaft within the socket or hosel 3. The socket or hosel 3 is provided with a tapered bore to receive the end of the shaft which is correspondingly tapered as at 4, Fig. 2, to fit within the hosel or socket 3.

Milled orotherwise formed in the walls of the socket or hosel 3 in spaced relation is "a series of longitudinally disposed slots 5.

These slots are of considerable length as compared with their width and extending longitudinally are substantially alined with I the rain of the shaft. :lhese slots are preferabdy although not necessarily inclined at their-opposite ends as at 6, and the method of producing the slots incidentally adords at the angle or apex ofthe inclined ends of I J 50 hole will not expose the wood.

' round holes or holes of area at various points throughout the walls the slots inturned burs 7 The tapered end or tenon of the shaft 1 is forcibly pressed or driven into the hosel 3, the tapered engagement with which serves to compress to some extent the fibers of the wood shaft where they forcibly engage with the walls of the hosel. The shaft material being unconfined in the area of the slots 5 tends to swell or expand slightly into said slots as the shaft is driven further and more firmly into the hosel or socket. The shaft tenon t may be coated with cement rial before bein introduced into the hosel 3 if so desired. ikewise it is possible to set or contract the she or feather edge of the inclined endsfi of t rial of the shaft tenon by'applying a suitable tool thereto and striking a sharp blow.

This would serve the same purpose as the bur 7 before referred to which upon any loosrm-- ing tendency of the shaft tends to embed itself in the wood and serves as a detent or spur to prevent the withdrawal of the shaft tenon. However, for ordinary purposes it will be found that the bur incidental to the production of the slots the further setting of touch material into the slots as shown in a somewhat exaggerated form in Figs. 2 and 3- gcint between the afiords an interlochng shaft and the socket or hosel which tends to resist any torsional or twisting strain. expansion of the wood fiber into the slots afiords lotud' al ribs or bonds. To further secure the shaft in positioma transverse pin 8is passed through the walls. of the hosel and through the shaft. However, the interlocking joint adorded' by the expansion of thewood fiber into ribs or beads engaging in the longitudinal slots 5 relieves the transverse pin 8 of the torsional or tw1st-.

ing strainincident to the use of the club and thereby obviates the the shaft as before mentioned.

It has not been unusual heretofore to comparatively small of the hosel or socket for the purpose of reducing weight.

However, a small or round. V suficient length of wood fiber to permit the swelling or expansion necessary to provide the interlock before referred to. It will be readily understood that the wood will swell or expand to much greater degree if confined at widely separated points in of'the fiber or the grainof the wood than if the points of confinement are closely located. The longitudinal slots thus induce a greater degree of-expansion and afford an additional and new function not attainable by the mere haphazard dispositiorrof round drillholes.

From the above description it will be apparent that there is thus provided a device of the character or other adhesive mate-- e slots 5 into the mate- Y is suficient without the sharp edge into The lateral swelling of the shaft I The danger ofsplitting socket, and a handle the direction of the length incense described, possessing the particular features of advantage before enumerated as desirable but which obviously is susceptible of modification in its form, proportion, detail construction or arrangement of parts, without departing from the principle involved or sacrificing any of its advantages. While in order to comply with the statutes, theinvention has been described in language more or less specific as to certain structural features, it is to be understood that the. invention is not limited to any specific details, but that the means and construction herein described comprise but one mode of putting the invention into sheet, and the invention is, therefore claimed broadly in any of its possible forms or modifications within the scope of the appended claims.
