GOLFCLUB Filed Nov. 21, 1930 Patented Nov. 6, 19 34 UNITED STATE- OFFICE Claims.

I The object of this invention is to attach the metal heads of golf clubs to their shafts by a new method, and to provide improved means for attaching these heads to their shafts, whereby it 5 will be impossible to detach the head from the shaft or to twist it around the shaft in any direction, once the hosel of the head has been connected to the shaft by the present improved means and novel method.

I have found in practice that the only way the head of the club can be detached from the shaft, When my invention is employed, is either by breaking off the head or sawing it oif.

I am aware that the construction and method involved in my present invention, while shown and described in connection with a golf club, may be embodied in any tool, implement, device or appliance where a metal sleeve, neck or hosel is connected to a wooden or metal handle, shank, staif, or the like and I wish it to be understood that in the claims, I do not limit the invention to use in connection with golf clubs.

The principle involved in the mechanical means or construction is that of a wooden or metal shaft, shank or handle having a doubleconed part in its completed form, the outer cone being originally cylindrical and formed into its cone shape by a wedge, and a neck or hosel which has a double-coned internal bore fitting the double coned part on the shank or handle and conforming thereto when the wedge is driven home. The method involves the formation of the outermost cone by the step of pressing or driving the hosel onto the specially formed shank, during which step the wedge is driven home, thereby expanding the outer part of the wooden or metal shank into the outer part of the double-coned bore of the hosel.

To prevent the hosel or neck from turning on the shank or shaft, means, such as lugs or fins, are provided on the interior of the hosel which form grooves or depressions in the innermost section of the double cone during the step of driving the hosel into position and thus they embed them- 4&2 selves and resist any turning or twisting action.

A practical embodiment of the invention is hereinafter described and is shown in the accompanying drawing, in which:

Figure 1 is a detail View partly in section, of

:so my invention, showing the club head in a position ready to be assembled;

Fig. 2 is a similar view of the invention assembled and ready for use;

Fig. 3 is a section on line 3-3 of Fig. 2; Fig. 4 is a section on line 4-4, Fig. 2; and

Fig. 5 is a section on the line 5-5, Fig. 2.

The wooden or metal shank of the club appears at 1, being provided with a tang or chucked end comprising a tapered or coned section 2 and a section 3 which, in its original form, is cylindrical but is subsequently formed into cone shape. The sections 2, 3 are integral parts of the wooden or metal shaft or shank 1 and may be said to adjoinat 4. A shoulder 4 adjoins the larger base of the coned section 2 and serves as an abutment for the end of the hosel or neck.

The hosel or neck 6 of the club-head 7 has a bore o-r socket comprising a tapered section 8 which is of substantially the same internal diameter and length as that of the external diameter and length of the section 2 of the tang. In other words, the part 8 of the bore extends from a point substantially at the junction 4 to the shoulder 5 so that this part 8 of the bore will snugly fit the coned section 2 when the hosel is driven into position.

The tapered section 9 of the bore or socket extends from a point 4 to the solid end wall where the hosel connects to the club head 7. The taper of the section 9 need not be as great as that of the section 8 and, preferably, is less. The bottom part of this section 9 is oval as at 9', Fig. 5.

A metal wedge 10 is employed to spread the section 3 into the tapered part 9 of the bore. Originally, a thin sawkerf 11 is provided in the section 3 of the tang to receive the wedge 10 when the parts are assembled by the method hereinafter described. The wedge serves tospread the section 3 of the tang so that it assumes a cone shape or form in the completed article. Thus, in its final form, the tang is of doubleconed shape, the sections 2, 3 thereof snugly fitting the tapered sections 8, 9, 9' of the bore, respectively.

From the interior of the section 8 of the bore,

project one or more tapered lugs or fins 12 which, by the step of driving the hosel into its final position, forms grooves or channels 12 extending lengthwise of the coned section 2 of the tang, thus locking the hosel on the tang against any possibility of turning thereon, the oval form at 9' assisting in this locking action.

The method involved in combining the club 7 and its hosel 6 with the tang 2, 3 and the shaft 1, is carried out by the following steps. Assuming that the shaft 1 and the tang 2, 3, the latter having the kerf 11, have been previously formed and that the neck or hosel 6 has been provided with a bore having the tapered sections 8, 9, the

first step is to insert the point of the wedge in the kerf 11.

The next step is to slip the outermost part of the bore 8 over the substantially cylindrical section 3 of the tang. It will be understood that only the point of the wedge will be inserted in the outer end of the kerf 11 because if the section 3 of the tang is unduly spread, it cannot pass the point 4 representing the constricted part of the bore 8, 9. By driving the club head '7 onto the tang, eventually the solid part of the club head '7 representing the bottom of the socket or bore 8, 9, comes in contact with the wider end of the wedge 10 so that, on further driving of the club head, the wedge 10 is pushed farther and farther into the kerf 11, resulting in expande ing the section 3. Finally, when the open endof the bore 8 strikes the shoulder 5, the section 3 of the tang is fully expanded into the tapered part 9 of the bore, thus positively locking the hosel on the tang and preventing any detachment therefrom, due to the double-coned form of the tang and the fact that it fits the double-coned parts 8 9 of the bore.

The'tapered lugs or fins l2 encounter the tapered part 2 of the tang and dig deeper into the said part the farther the hosel is driven onto the tang, meanwhile forming the grooves "12 and effecting an interlock between the hosel and the tank which prevents the hosel from twisting on the tang. The oval part 9 of the bore assists in maintaining this interlock.

What I claim is:

1. Means for connecting a golf club head, implement, or tool to its shaft or handle, comprising a neck or hosel provided with an internal double-coned bore which is narrowest at a point intermediate its ends, the outermost part of which has a fin or member projecting from the wall thereof inwardly into the bore, the innermost part of the double-coned bore being cross sectionally of oval shape, and a double-coned tang carried by the shaft or handle and fitting the bore of the two sections of the double cone of the hosel and interlocked with the projecting fin aforesaid, whereby both coned parts of both the tang and hosel are prevented from relative turning and from being disconnected.

2. Means for connecting a golf club head, implement, or tool to its shaft or handle, comprising a hollow neck or hosel having an elongated projection extending into its hollow interior from the wall thereof and which extends lengthwise of the hosel, a tang carried by the shaft or handle with whose surface the aforesaid projection interlocks lengthwise thereof to prevent the hosel and tang from turning in relation to each other, and means for preventing the hosel and tang from pulling apart.

3. Means for connecting a golf club head, implement, or tool to its shaft or handle, comprising a hollow neck or hosel having an elongated projection extending into its hollow interior from the wall thereof and which extends lengthwise of the hosel, a tang carried by the shaft or handle in whose surface the aforesaid projection becomes embedded lengthwise of said tang by the act of telescoping the hosel and tang together, thereby to interlock the hosel and tang lengthwise thereof and prevent them from turning in relation to each other, and means for preventing the hosel and tang from pulling apart.

4. Means for connecting a golf club head, implement, or tool to its shaft or handle, comprising a neck or hosel having a bore which tapers inwardly from the tang-receiving outer end thereof and whose wall is provided with an elongated tapered lug or fin projecting into said bore and which extends lengthwise of the hosel, a tang carried by the shaft or handle and received within the tapered bore of the hosel, in which tang the tapered lug or fin embeds itself lengthwise of said tang by the act of telescoping the hosel and tang, thereby to interlock them lengthwise and prevent relative turning of the hosel and tang, and means for preventing the hosel and tang from pulling apart.

5. Means for connecting a golf club head, implement, or tool to its shaft or handle, comprising a neck or hosel provided with an internal double-coned bore which is narrowest at a point intermediate its ends, the outermost part of which has an elongated 'fin which extends lengthwise of the bore and projecting thereinto, and a'double-coned tang carried by the shaft or handle and fitting the bore of the two sections of the double-cone of the hosel and interlocked lengthwise of the tang with the projecting fin aforesaid, whereby the tang and hosel are prevented from relative turning and from being disconnected.
