Sept. 24, 1935. A. BUHRKE ET AL GOLF CLUB` Filed Aug. 16, 1952 Patented Sept. 24, `1935 UNITED STATES ATENT OFFICE GOLF CLUB Application August 16, 1932, Serial No. 629,064

15 Claims.

The invention relates to a new and improved construction of golf clubs and particularly to the construction of a golf club of the type commonly referred to as a wood or wood club,

5 that is, having a wood head or a head made of wood or analogous fibrous material having an integral shank or neck to which is attached the usual club shaft such club being commonly called a driver, brassie or spoon. In the present l embodiment of the invention the wood club head is shown attached to a flexible metallic shaft handle formed at its attaching extremity of a generally cylindrical shape that may be tapered according to common construction of tubular, tapered metallic shape, commonly used at the present time for shafting of wooden-headed clubs, in order that the shaft may present its maximum degree of flexibility toward the lower or club attaching extremity of the shaft. While the shaft in the present embodiment is shown of cylindrical form it should be understood that the invention may be applied to a golf club having a shaft of a plurality of sides, as, for example, instead of being precisely circular in crosssection it may be formed of many sides, as hexagonal or octagonal form in cross-section.

It is the primary object of our invention to provide an improved form of attaching joint between the shaft and the shank of a woodheaded club.

A further object of our invention is to provide an improved construction of joint for securing and connecting the shaft of a wood-headed club to the neck or shaft of its club head in such manner as to dispense with the common use of a whipped or wrapped joint and to secure the maximum strength of joint at the initial point of union between the shaft and the neck or shaft of a club head, whereby to prevent failure or loosening of the joint while in use after assembly and particularly to prevent splitting of the shank or neck of a wood club head.

It is a further object of the invention to provide an improved connection between a flexible metallic shaft of general cylindrical form including shafts having a plurality of regularly formed sides as hexagonal or octagonal shafts in cross-section and which connection will permit of a degree of flexibility in the tubular shaft adjacent to the connection without tending to split the upper end of the neck or shank of the club head within or adjacent to the joint whereby to avoid failure of the joint and splitting and consequent damage to the club head and its shank.

A further object of the invention in a Woodheaded and flexible shafted club of the described character is to provide an improved vform of connecting joint between the club head and the shaft but which will permit of a degree of flexing j and torsional distortion in the flexible shaft adjacent the joint without injury to the material in the neck or shank of the Wood club head.

It is a further object of the invention to provide an improved connection of a substantially pleasing and ornate character, obviating the appearance of the ordinary wrapped or whipped joint between the shaft and shank of the golf club head.

Other objects of the invention will appear from the following description, which is directed to the preferred embodiment of the invention and hereinafter described with reference to the drawing, which forms a part of the specification, the features of novelty being set forth in the appended claims.

In the said drawing:

Fig. l is a side elevational view of a club head and its attached shaft embodying the invention, and Fig. 2 is a similar view taken at right angles to the View shown in Fig. 1, parts of the shafts intermediate the respective handle grips and club heads in each of said views being broken away, and the form of the invention in Fig. 2 being slightly modied over the form of Fig. l with respect to the construction of the elongated ferrule around the shaft above the joint proper.

Fig. 3 is an enlarged fragmentary'longitudinal sectional view taken on line 3 3 of Fig. l looking in the direction indicated by the arrows, disclosing the details of construction of our improved head and shaft connection.

Figs. 4 to '7, inclusive, are side elevational views of detached parts of our improved joint between the club head and shaft further illustrative of the details of construction thereof. 4

Fig. 8 is a broken enlarged longitudinal sectional view similar to Fig. 3 setting forth in detail the construction of a slightly modified form in Fig. 2, the view being taken on the broken line 8-8 of Fig. 2, looking in the direction of the arrows.

Fig. 9 is a fragmentary detached View of a portion of the downwardly tapered shaft of Fig. 8 with the spaced apart shaft and ferrules shown in attached position thereon.

Like parts are indicated by the same reference characters throughout the several views of the drawing.

The reference character l0 designates generally the head of a golf club of the type and char- 55 acter heretofore referred to to which the invention is applied, I I being the striking face thereof and I2 (Figs. 1, 2, 3, 7 and 8) being the neck or shank portion tapered for the attachment of the shaft I3 shown in the drawing of a hollow or tubular tapered metallic form, the upper extremity of the shaft to which is secured the usual handle grip I d being the end of the shaft having a larger diameter while the taper in the embodiment shown extends more or less uniformly from the handle grip portion I4 to the lower extremity or terminus of the shaft where it is seated and attached in the club head.

Heretofore in the construction of the Shanks and necks of the wood type of club heads it has been customary to taper the neck or shank I2 upwardly with a more or less uniform taper towards its upper terminus, thus producing substantially a knifelike or featheredge at the upp er extremity of the neck or shank portion of the club head when said neck or shank is bored with la central longitudinal bore as designated at I5 (Figs. 3, 7 and 8) to receive the lower and usual tapered extremity of the shaft I3. We have found by experiment and practice that where the upper extermity of the neck or shank of a wood club head is reduced to a knifelike or featheredge that it is exceedingly diflicult to reinforce by any form of wrapping, whipping or protecting ferrules such upper extremity of the neck or shank of the Wood club head so as to prevent splitting which has a marked tendency to start when such joint is covered and closed by wrapping or whipping or by the use of ferrules, in the knifelike Aor featheredge extremity of the neck or shank on account of such flexing or movements as inevitably take place in the normal use of the club in striking an object as a golf ball, the comm-on result being that splits or cracks in the knifelike or featheredge extremity of the neck or shank of the club head will start within the normally covered confines of the joint, and because of the ordinary tapered construction of the neck or shank of the club and will extend downwardly into the thicker portions of the neck or shank and ultimately extend in some cases even to the head itself, often resulting in such splitting and damage to the neck and head of the club as to loosen the head and impair the eiciency of the same and to shorten or terminate the period of its useful life.

In the formation of our improved joint we terminate the tapered portion I2 a substantial distance below the upper terminus of the neck or shank as designated at I 6 (Figs. 3, 7 and 8), and thence upwardly to the upper terminus of the neck or shank the material is given a cylindrical form as designated at II, so that when the shaft bore I5 in the neck or shank and into the clubhead is made the part I'I will be of cylindrical or non-tapered form and will also be of substantial thickness as illustrated in the drawing to present a substantial amount of material in the shank or neck for the seating of a protective ferrule therearound to serve as a firm support not only for the cylindrical portion I'I but for the tapered upper extremity of the neck or shank of the club head. Such a ferrule We prefer to be made of a light, tough, rm metal as, for example, aluminum, as designated by the reference character I8 (Figs. 3, 6 and 8), and will be bored at its upper extremity to take a close lor drive t, as indicated at I9, around the cylindrical neck extension II, fitting thereover when inserted with a close or drive fit over the neck of the shank substantially as far down as the termination I of the cylindrical part I'I and being thence flared outwardly and downwardly to fit closely around the tapered portion of the neck I2 of the club head, terminating preferably at its lower extremity with a somewhat thinned lower edge or skirted to conform closely around the tapered material of the neck of the club head. For ornamental purposes we prefer to keep the metallic ferrule 58 thin enough that it may take an ornamental covering or sleeve 29 (Fig. 5) of pyroxylin or Celluloid or analogous ornamental.

material. As, for example, the ferrule I8 may be covered with a' relatively thin coating of enamel, under which conditions it could be made to conform with the cooperating parts of the joint and the aluminum or other material of which it is made would accordingly be made thicker than illustrated in the drawing if it be merely cove red with an enameled coating instead of the pyroxylin of the ferrule herein shown and described. The aforesaid lower extremity of the ferrule IS is designated by the reference character 2?, the upper extremity of the lower portion 21 being thickened to correspond with the thickness of the pyroxylin coating 20. On the shaft I3 we xedly secure a metallic ferrule 2 I, the function of which is to swivelly contact with and bear upon the upper extremity of the metallic club neck ferrule I8. To accomplish this the pyroxylin cover 2li of the metallic ferrule I8 will be slightly shorter than its seat portion on the part I8 so that a portion of the upper extremity of ferrule E8 will be normally uncovered by the covering 20 and the shaft ferrule or ring 2I will preferably have a peripheral recess next the shaft opening as indicated at 22, which when the parts are assembled in the manner illustrated in Fig. 3, will cause the ferrule I8 to seat in position metal to metal for swivelly terminating in the lower extremity of the ferrule 2I. the ferrule 2I which will preferably be of firm metal as aluminum will be preferably made to the shaft by shrinking the same thereon due to the preferred downwardly tapering portion of said shaft. the ferrule 2| will preferably be corrugated to furnish a connective seat for the lower extremity of a joint closure ferrule 23, which may be formed of pyroxylin or Celluloid of any well known character and caused to extend upwardly for some I distance along the shaft for ornamental and joint strengthening and finishing purposes. The pyroxylin ferrule 23 like the metallic ferrule 2I will be fixed to the shaft by reason of the drive fit form when the tapered shaft is forced downf wardly into the ferrule 23 and its metallic cooperating and locking part 2| in the joint assembly as hereinafter described.

In assembling the conical type of hollow tube metallic shaft herein shown and described the club head and neck are prepared and bored and the ferrule I8 will be placed with a close or drive iit upon the upper extremity of the neck I2 of the club head with the cylindrical bore of the ferrule i8 corresponding with the cylindrical portion I'.' of the club head shank and with the skirted portion of the ferrule I8 tapering and enlarging downwardly and outwardly in firm wedging position around the tapered shank l 2 of the club head in the manner illustrated more clearly in Fig. 3. When the ferrule I8 is in its normal position en shank parts I2 and II as shown the pyroxylin ferrule 23 will be placed upon the shaft I3 and forced upwardly therealong by means of the cooperating The attachment of The outer periphery of the body of i metallic. swivel ferrule 2| until the ferrule 2l has substantially reacheda seating position on the shaft, which will leave a portion of the lower tapered extremity of the shaft I3 protruding below the ferrule 2l and ready to be inserted in the bore l5 in the neck or shank of the club head. The parts may be brought into firm assembled relation by tapping or driving upon the upper extremity of the shaft I3, which will cause the shaft to further enter the bore of the clubhead with a wedging, binding action until all looseness in the joint is taken up, after which the shaft it may be secured in fixed non-rotative relation in the bore in the club head by any of th-e ordinary expedients employed for this purpose Such as the boring of registering holes through the shaft and club head and the passing of screws or metallic locking pins therein, such shaft-locking means not being herein shown and described since the same forms no part of the present invention.

In the modified form of the invention shown in Figs. 2, 8 and 9 we illustrate a construction by which a ,joint finishing ferrule of the character of the ferrule 23 shown in Figs, l and 3, may be more firmly and substantially anchored to the shaft and a modified ornamental appearance secured. The ferrule is divided into two or more sections, as designated by the reference characters 3--3!, 3l being the thicker section at th-e joint end of the ferrule constructed precisely in accordance with the lower end of the before described ferrule 23 and being secured in the same manner to the knurled ferrule 2l'. 32 is a metallic ferrule that may be secured with a drive fit upon shaft i3 in the same manner as the shaft ferrule 2l, and the ferrule 32 will preferably be provided with an intermediate peripheral flange 33 and will be adapted to take the abutting ends of the ferrule sections Sil-3l, the adjacent cooperating ends of these sections being undercut or enlarged to fit over the body portion of the connector ferrule 32, thus exposing the enlarged peripheral flange portion 33 between the sections 35-3! for ornamental purposes, in the same manner as the enlarged peripheral flange 3d at the lower end of the ferrule 2l (Figs. 1, 2, 3 and 8) is provided to secure an ornamental effect between the before described ferrules 20 and 23. There is an advantage in the use of the plurality of shaft ferrules 2l and 32 because of the double anchoring effect to the extended ferrule sections StL-3|. Obviously also the effect of the plurality of ferrules 2l and 32 may be further enhanced by elongating the total length of the shaft ferrule and providing more than one intermediate anchoring ferrule of the character of the ferrules 2l, 32 respectively,

In forming a mechanical connection or joint at the upper tapered end of the neck or shank of a wood-head club and its shaft one of the difcult problems involved is to avoid the provision of joints of a character that may open in use and so cause gaps between abutting or contacting f parts likely to throw undue strain upon the shaft in the joint connection. Our improved Yconstruction as described in the embodiment shown Yin Figs. l to 7, inclusive, is illustrative of the improved form of jomt that has been found pleasing in ornamental effect and to provide a joint that will permit of a certain amount of torsion and flexing of the shaft in relation to the neck and shank of a club without opening up the joint due to any tendency of the parts of the connecw tion to slide longitudinally of the shaft, while the modified sectional ferrule of Figs. 2, 8 and 9 provides additionally an improved and ornate means ofsecuring an elongated ferrule in joint combination upon the lower extremity of the golf club shaft. Furthermore, the improved joint provides a flexible and skirted connection between the shaft andthe club head, which makes unnecessary the use of any wrapping or whipping material and provides an ornate joint in which the necessary strength for providing a permanent and efficient joint connection is 'not dependent upon elastic or more or less flexible materials such as thread wrapping and whipping or pyroxylin or other flexible and more or less elastic materials heretofore utilized in securing and bracing of l5Y the joint, the connecting elements as provided being of firm and strong metals while capable of ornamentation if desired, by plastic or other ornate coverings, thus providing a durable and efficient as well as a flexible joint that will not detract from the normal torsibility of the flexible club shaft adjacent its point of connection with the club head since relative rotation is permitted between the metallic sleeves E8 and 2l aiiixed respectively to the neck of the club head and to the shaft when torsion takes place in the'lower reduced and weaker end of the shaft adjacent the club head whenever the -club head strikes the ball or other object in play.

In order that the invention might be understood, the details of the preferred embodiment thereof have been set forth with particularity, but it is not desired to be limited to such details except as specified in the claims, since it will be apparent that persons skilled in the art may resort to various modifications in the structure shown and described without departing from the purpose and spirit of our invention.
