Definitions
- club heads it is necessary to weigh the club heads to provide a proper swing weight.” This is provided in woods by boring a cavity in the soleplate of the wood club head and then inserting a weighted filler in the form of a lead slug or a molten lead.
- a weighted filler in the form of a lead slug or a molten lead.
- the club heads are made to known weights but there have been variations in the shaft and the gripper weight due to the lack of uniformity of the length of insertion of the shaft into the club heads. Thus, some sort of weight must be added to the tip of the shaft during the assembly thereof to provide uniformity of club weight.
- This invention is directed, in brief, to the provision of a head-to-shaft connection for a golf club wherein the shaft end and hosel bore are aligned during assembly by means of separate spacer elements with bonding or cementing means filling the space between the hosel bore and the shaft.
- the axial insertion of the shaft into the hosel may be limited by the bottom of the hosel bore.
- adjustment for length of different shafts may be made by cutting ofi' portions of the distal end of the shaft leaving the gripping end of a constant axial length. This permits the use of a single shaft for all irons and a single shaft for all woods.
- these advantages are obtained by forming the shaft with a straight end instead of a taper and forming a straight hosel bore in the head rather than a taper bore.
- a plug of desired weight may be connected to the end of a shaft for providing the desired swing weight.

- FIG. 12 is a fragmentary section view showing still another modified form of centering the shafts at the bottom of the hosel.
- the golf club 10 shown in FIGS. 1 and 2 of the drawings is that type commonly referred to an iron.
- the club includes a generally round shaft 12 attached to the club head 14 which is the portion of the club utilized for striking a golf ball during play.
- the shaft includes a handle or grip portion 15, a shank portion 16 intermediate the ends of the shaft, and an end or tip portion 18 which is connected with the hosel 20 of the club head 14.
- End portion 18 is preferably of a generally constant diameter and the length of the shaft is preferably longer than necessary for any club with which the shaft is to be used. Adjustments for proper length may be made by cutting the end portion 18 as described in my copending US. Pat. application, Ser. No. 749,681, filed Aug. 2, 1968, entitled GOLF CLUB SHAF'IS.
- I-Iosel 20 extends upwardly from head 14 and is provided with a shaft-receiving opening or bore 22 of generally constant diameter throughout most of its length. This bore is larger than the outer periphery of the end 18 of shaft 12 and includes a countersunk or first stepped portion 24 at the free end 25 of the hosel.
- the ferrule has a reduced end portion 30 which snugly mates with the countersunk portion 24 at the top of the bore 22.
- Ferrule 26 has a small recess 31 at the juncture of reduced portion 30 for receiving bonding material.
- the ferrule is formed to accurate dimensions, such as by molding the ferrule from plastic material, so that it may center the shaft 12 coaxially relative to the bore 22.
- a plug 32 which may be weighted, may be inserted in the opening of end 18 to center the shaft relative to bore 22 and to provide the desired swing weighting for the club.
- a cementing or bonding substance 34 is applied in the space between the shaft tip 18 and the bore 22 for securing the shaft 12 to the head 14. If desired, a pin could be inserted through the shaft and hosel.
- Plug 32 is preferably formed so that its first or reduced portion 38 snugly mates with the inner diameter 40 of shaft 12 and its second or enlarged portion 42 snugly mates with the hosel bore 22. This further serves to coaxially align or center shaft 12 relative to bore 22 upon assembly of the shaft to the club head.
- FIG. 2A is a modified form of the structure shown in FIG. 2.
- the hosel 20 has a reduced portion 41 at the lower end of bore 22, forming a shoulder 410 against which tip 18 of shaft 12 abuts.
- the enlarged portion 42a of plug 32 is intended to be snugly received in reduced bore portion 41.
- club 12 is that type commonly referred to as a wood.
- the club includes the same type of shaft 12, and similar reference numerals have been used to indicate identical portions of the shaft.
- Club head 44 has an upwardly extending hosel portion 46 which is provided with a shaft-receiving opening or bore 48 of generally constant diameter throughout most of its length. This bore is also larger than the outer periphery of the end 18 of shaft 12 providing a space 49 for receiving bonding material.
- the free end of the hosel may have a reduced outer diameter 50 providing a shoulder 52 and a second reduced diameter portion 54 providing a second shoulder 56.
- Ferrule, bushing or centering means 58 has a generally constant diameter bore 60 generally of a size and shape to snugly embrace the portion 18 of the shaft and a generally frustoconical bore portion 62 which mates with the tapered reduced portion 50 of the hosel.
- the ringlike end 64 of ferrule 58 abuts the shoulder 52 to limit the insertion of the hosel portion into the frustoconical bore portion 62.
- Suitable adhesive means 66 is provided in the space between the reduced diameter portion 54 and the transitional area 68 between the straight bore portion 60 and the frustoconical bore portion 62 of the ferrule 58.
- the bore in the hosel of the wood club head may terminate in a shoulder structure similar to that shown in FIG. 2, preferably the bore is formed as shown in FIG. 4 where the bore opens through the bottom of the club head.
- the desired weighted plug 70 is positioned in the free end of the tip 18 of the club shaft, and bonding cement 34 is applied in the space between the tip 18 and the bore 48 as well as between the bottom of plug 70 and the baseplate 72.
- FIGS. 7-9 show modified forms of centering the end 18 of the shaft in the hosel bore by means other than the ferrule arrangement disclosed with respect to FIGS. 2 and 4.
- the end 18 of the shaft could be centered in bore 22 by means of radially inwardly projecting shoulders 74 which could be machined to close tolerances.
- radially outwardly extending projections 76 are formed on the shaft end 18 to center the same with respect to the bore 22.
- the end 18 of the shaft is centered in the bore 22 by means of a separate annular spacer ring 78.
- FIGS. -12 show alternate means for centering the shaft end 18 in the bottom of the hosel bore.
- the bottom of the hosel bore is provided with a stepped shoulder 80 on which the shaft end tip 18 abuts, with the adjacent sidewall 82 formed to close tolerances with the outer diameter of the end 18 to center the same with respect to the hosel bore 22 so that the club shaft is coaxial with the hosel bore.
- shaft end 18 is provided with radial enlargements 84 formed to a close tolerance with the hosel bore 22 so as to center the lower end of the shaft with respect to the lower end of the hosel bore.
- a spacer such as 78 referred to in FIG. 9 could also be provided at the lower end of the hosel bore 22 for centering the shaft end 18.
- both the hosel bore 92 and the tip 94 of the golf club shaft are tapered.
- the taper of the hosel bore is shown as 6 being at a wider angle than that of the golf club shaft though the two could be formed with the same taper.
- the shaft is oriented with respect to the hosel bore by means of a ferrule element 96.
- the shaft tip 94 and hosel bore 92 are fitted to cause centering of the shaft tip 94 and the hosel bore 92.
- the shaft 94 is plugged at the end with plug 98 to prevent bonding material from entering into the interior of the shaft.
- shaft 12 is shown angularly oriented relative to the hosel 20.
- both the tip 18 of the shaft and the bore 22 of the hosel are of generally circular cylindrical configuration.
- the spacer elements or ferrule means 102 are provided with offset or eccentric openings.
- the shaft 12 will be angularly disposed with respect to the hosel 20.
- suitable cementing or bonding means may be introduced in the space 106 between the shaft tip and the hosel bore to hold the elements in the desired orientation during assembly. It has been found that this type of assembly of the elements is most suitable for building in a club head-toshaft relationship wherein the head will be closed or open relative to the shaft to suit the needs of the individual golfer.
- connection of this invention eliminates the need for stocking several different club shafts for different golf clubs. All adjustments in the length of the club shaft can be made by cutting off the distal end of the shaft prior to final assembly of shaft and club head. Assembly of the shaft and club head is no longer dependent upon the close relationship of the shaft and to the club head hosel. Instead, suitable spacer elements or ferrule means are interposed between the shaft tip and the hosel bore to orient the shaft as desired with respect to the club head, following which a bonding substance is interposed in the space between the shaft and bore. Once the bonding substance cures, it positively holds the components in the desired relationship.
- relative length of the shaft for each club head may be determined by cutting a portion from only the head end of the shaft, and the limit of the insertion of the shaft into the hosel bore may be determined by abutment of the shaft with the bottom of the bore and not by the facial engagement between the tapered sidewalls of the bore and the tapered end of the shaft.
- a golf club head-to-shaft connection comprising;
- a golf club head including an upstanding hosel having a bore therein substantially larger than the head end of the shaft, said hosel bore having an open end and a closed end, said open end having a stepped configuration,
- a golf club shaft having a handle end portion and a head end portion, said head end portion being untapered and inserted in said hosel bore,
- said positioning means including first means located at said closed end and separate from said hosel for axially positioning the lower extremity of the shaft at the base of the hosel bore and apart from the walls of the hosel bore, and second means separate from said hosel for axially positioning the shaft at the said open end of the hosel bore, said second means fitting tightly about said shaft head end, said second means having a correspondingly stepped configuration as said open end for placement thereon, with said secondmeans step being substantially wider than said open-end step thereby positioning said shaft away from the walls of the hosel bore and bonding material disposed and filling the void between the head end portion of said shaft and the wall of the hosel bore so as to bond the entire outer surface of that portion of the shaft within the bore directly to the wall of the hosel bore.
- said shaft is hollow, and further including means to plug the open end of said hollow shaft, and wherein said plugging means comprises said first means for axially positioning the lower extremity of the shaft at the base of the hosel bore and apart from the wall thereof.
- said closed end of the bore includes a shoulder, receiving thereon a portion of the distal end of the shaft, limiting the penetration of the shaft into the hosel bore, said shoulder being comprised of an annularly reduced area of the bore.
