7 claims. A(ci. 27s- 80) This invention relates to a metal shaft for a golf club or the like. Because of the scarcity and high cost of wood suitable for forming shafts for golf clubs metal shafts are being used in increasing numbers. Because of the inherent characteristics of the metal great difficulty has been experienced in producing a metal shaft having the desirable characteristics of the Wooden club. So far as I am aware it has been found impossible heretofore to provide a metal shaft which would have the feel of the wooden shaft. A club having a metal shaft will almost invariably sting the hands of the player when the club tops the ball or strikes hard ground and, further, the whip or resiliency of the shaft cannot be controlled. Variations in the metal from which the shaft is formed will result in different amounts of resiliency in different shafts and the resiliency will be located at diiferent points in the length of the shaft, thus making it practically impossible to produce any given number of clubs having exactly the same feel.

One object of the present invention is to provide a metal shaft for a golf club which will have the feel of the wooden shaft and will not sting the hands of the player.

A further object of the invention is to provide a metallic shaft for a golf club of such a character that the amount of resiliency thereof and the location of that resiliency can be accurately controlled in the manufacture cf the club, thereby enabling any desired number of clubs to be manufactured with exactly the same feel.

A further object of the invention is to `provide a shaft or golf club having relatively great strength in proportion to its weight.

A further object of the invention is to provide such a shaft which can be produced at a low cost.

Other objects of the invention will appear as the device is described in detail. l

In the accompanying drawing Fig. 1 is a plan view of a portion of the metallic ribbon from which the shaft is formed; Fig. 2 is a side elevation of the shaft after it has been fully wound; Fig. 3 is a longitudinal sectional view of a portion of such a shaft; Fig. 4 is a longitudinal section of a portion of a slightly modiiied form of shaft; Fig. 5 is a transverse section taken on the line 5 5 of Fig. 3; Fig. 6 is a transverse section taken on the line 6-6 of Fig. 4; and Fig. 7 is a side elevation of a golf club embodying the invention.

In the drawing I have illustrated one embodiment of my invention and have shown the same as comprising the shaft for a golf club but it will be understood that this particular embodiment has been chosen for the purposes of illustration only, and that the shaft may take different forms and may be used for various purposes.

The I shaft comprises an` elongated tubular structure formed of spirally wound metal. Preferably a single thin strip or ribbon 1 of suitable metal, such as steel, is wound in spiral formation to provide an elongated tubular structure andv the 'adjacent vwindings are mounted in overlapping relation and are held in snug engagement one with the other. If desired, each succeeding winding, after the'second, may be caused to overlap at least two preceding windings, thereby providing the structure at -all pointsin its `length with three or more thicknesses of metal and enabling a very strong durable structure to be formed from a relatively thin ribbon of metal. As shown in Figs. 3 and 5 each succeeding winding overlaps two preceding windings and the wall ofthe structure is thus formed of three thicknesses of metal. In Figs. fl and Beach succeeding winding overlaps four preceding windings and the wall of the structure consists ofv five thicknesses' of metal.

The overlapping windings may be retained in proper engagement one with the other in any suitable manner but it is not essential that the superimposed windings be connected by any means other than their frictional contact. I-Iowever, it may ber desirable in some shafts to provide positive connections between overlapping windings and this may be accomplished in any suitable manner. By properly arranging such connections I am able to accurately control the resiliency or whip of the shaft. In the shaft here illustrated I have spot Welded the windings at intervals, as shown at l0, determined by the characteristics to be imparted to that shaft.

The characteristics which are embodied in a shaft for a golf club depend in part upon the type` of club in which the shaft is to be used and in part upon the preference of the individual players. These characteristics may, for the most part, be determined by varying the amount and location of the resiliency of the shaft, and this resiliencyV may be controlled in several ways. First, by varying the angle at which the ribbon is wound and/or the number of thicknesses of metal in the wall of they structure; second, by varying the spacing of the connections between the overlapping windings, and, third, by trimming the edge of the ribbon to reduce its Width at cer# tain points. A shaft in which there are no positive connections between the overlapping windings will have a relatively great resiliency, while a shaft in which the windings are so connected as to prevent all movements thereof with relation one to theother will be relatively stiff. By varying the number of connections and the arrangement thereof various degrees of resiliency may be obtained. The connections may be spacedV uniformly throughout the length of the shaft or the spacing may be varied in those parts of the shaft where more or less resiliency is desired.

While the width of the ribbon and the number of windings may vary, as above explained, I have secured very satisfactory results by using a ribbon of metal approximately three inches in width and so winding the same that each succeeding Winding will overlap the next preceding winding approximately two inches, thereby causing it to overlap the second preceding winding approximately one inch, as shown in Fig. 3. In the manufacture of the shaft the ribbon may be wound upon itself in any suitable manner, uponA a mandrel or otherwise, andthe windings thensecured in snug contactV one with the other. When such a structureis torbe employed as the shaft of a golf club it is tapered from o-ne end to the lother and the smallerend thereof is rigidly secured to the head 8 of the club while the outer or larger end of the shaft is provided with a covering `9, of leather oir-other'suitable material, to form a hand grip. Such a golf club has a feel substantially identical with that yof a Wooden shaft club and the spirally wound shaft will not transmit any appreciable vibration or sting from the head of the club Ato the hand of the player when the club tops the ball or hits hard ground. Further, the whip or resiliency cf the shaft can be very accurately controlled in the manufacture of the shaft by the methods above explained. By trimming or reducing the width of the ribbon at the desired points the amount of resiliency in any given part of the shaft may be increased beyond that provided` by the'spacing ofthe connections between thewindings. VBy varying the amount of overlap between adjacentwindings the shaft may be provided with a different number of laminations at different points in its length, as shown in Fig. 4. By trimming the smaller end of the tapered shaft, as shown inrFig. 4, or by so wind-- ing the shaft that the windings at theV smaller end thereof willoverlap for ,substantially their full width this small end may be provided with an increased number of laminations which will impart thereto relatively great strength at the point of connection with the head of the club, at whichY point the shaft is subjected to the greatest strain. Because of thisability to control the resiliency of the shaft any desired number of shafts may be constructed which will be identical in feel and whip, thus enabling a matched set of clubs to be produced in allof which the feel will be exactly the same. Because of its laminated construction the shaft maybe made very strong without increasing its weight above that desired, andthe positive connections between the windings prevents these from becoming loose and destroying the initial characteristics of the shaft. Such a shaft can be produced at a cost very much less than thatof other shafts now in use. I have alsof found that a club provided with such a shaft has much 'greater distance than clubs now in use, that is, v.a golf ball can be driven much farther with such a club than it can with other clubs.

While I have shown and described one embodiment of my invention I wish it to be understood that I do not desire to be limited to the details thereof as various modications may occur to a person skilled in the art. Y
