This invention relates generally to golf clubs,
`but has reference more particularly to golf clubs having angularly adjustable heads and to means for adjusting such heads.
This application is a division of my copending application, Serial No. 583,902, filed March 21, 1945, now Patent No. 2,475,926 granted July l2, 1949, which also relates to adjustable head golf clubs.
In my copending application, above referred to, I have disclosed an adjustable head golf club in which a radially movable member is utilized the character described, in which improved means `are provided for effecting the -release of the club head for adjustment purposes.
Another object of the invention is to provide improved means for locking the club head in its adjusted position.
Still another object `of the invention is to simplify the arrangement of the parts and reduce the number of parts required to effectively perform the aforesaid functions.
Other objects and advantages of the invention will be apparent during the course of the following description.
In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like lparts throughout the same, l
Fig. v1 is a longitudinal cross-sectional view of a golf club embodying the features of my invention.l
Fig. 2 is a fragmentary cross-sectional view taken on line 2-2 of Fig. 1.
Fig. 3 is a perspective view of one of the splined locking members used in the structure shown in Fig. 1.
Fig. 4 is an elevational detail on an enlarged scale of the head releasing pin shown in Figs. 1 and 2.
Fig. 5 is a view similar to Fig. 1 but showing a modified form of the invention.
Fig. 6 is a perspective view of one of the splined locking members used in that form of the `invention shown in Fig. 5. y
. Fig. 7 is a cross-sectional View similar to that z of Fig. 1, but showing still another modified form of the invention, and
Fig. 8 is a cross-sectional view taken on line 8 8 of Fig. 7.
Referring more particularly to that form of the invention shown in Figs. 1 4 inclusive, it will be seen that the pertinent structure includes a hosel 2 which has integrally formed thereon a shank 3 which extends at an obtuse angle thereto.
The shank 3 is provided with an outwardly extending circumferential shoulder 4 which serves as an abutment fora striking head 5 which is provided with a longitudinal bore 6 and which is rotatably mounted on the shank 3.
The shank 3 is provided with an intermediate portion i9 of slightly reduced diameter and terminates in an externally threaded stud Il of still further reduced diameter.
The head 5 is secured against axial displacement relative to the shank 3 by means of a capnut l, the head of which abuts one end of the :head 5, and the shank 8 of which is threaded internally for engagement with the stud Il, the outer surface Yof the shank 3 constituting, in effect, a continuation of the outer surface of the shank 3 so as to form with the latter a bearing surface for the head 5.
The wall of the bore 6 is provided with a multiplicity of inwardly extending circumferentiallyspaced serrations or teeth 9 which extend longitudinally of the head for a substantial portion of the length of the head, these serrations being practically coextensive in length with the length of the intermediate portion l0 of the shank 3.
The shank 3 is provided with an axial bore I2 which is counterbored as at I3 to provide a shoulder -l 4.
Extending radially from the portion of the bore l2 which lies in the intermediate portion Il) of the shank are a plurality of circumferentiallyspaced slideways or slots I5 in which are disposed splined head-locking members 49, each provided at its radially outermost face with a series -of parallel splines or serrations i6 which are adapted for engagement with the splines 9 of the head 5.
The members 49 are provided adjacent their ends with inclined surfaces All and 42, both of which surfaces are inclined in the same direction. A recess lil is provided on the members if] adjacent the foot of the inclined surface 42 and a recess I1 is also provided on the serrated surface I6 of the members.
The inclined surfaces 4l and 42 of the members 40 are engaged by conical cam elements 43 and 44 which extend from a pin 45 which is mounted for longitudinal reciprocal movement in the bore I2 of the shank, one end of said pin being enlarged to form a button 48 which projects out of the bore I3 of the shank 3.
The members 48 are normally maintained out of engagement with the serrations 9 by means of an annular spring I9 which is seated in an annular recess I8 formed on the shank portion I0, this recess being coextensive and in alignment with the recess I1 on the members 40. The spring I9 acts normally to retract the splined members 45 radially inwardly with reference to the shank and when thus retracted, the members 4 are out of engagement with the serrations 9 on the head 5, and the head 5 may be rotated. relatively to the shank 3.
Locking means are provided by the previously referred to cam elements 43 and 44 which are normally biased by a compression spring 46 into camming relationship to the members 4B. The spring 45 is interposed between the cap-nut 1 and the end of the cam element 43, and is substantially stronger than the spring I9.
In the position shown in Fig. 1. the members 40 have been forced into engagement with the serrations 9 of the head 5 by the camming action of the elements 43, 44 on the inclined surfaces 4I, 42, which camming action is caused by movement of the pin 45 to the right in response to the force exerted by the spring 46.
The interengagement ofthe serrations I6 with the serrations 9 causes the head to be locked against movement relatively to the shank, and
vthe head 5 will thus remain disposed in any selected position of angularity relative to the shank.
In order to release the head 5 from its locked position, the player merely pushes the button 48 to the left, as viewed in Fig. 1, against the action of the spring 45. This causes the cam elements 43, 44 to move out of lcamming engagement with the surfaces 4I, 42 of the members 48 and permits the spring I3 to become eifective to retract the members 4G in the manner previously described. l
The head 5 is then freely rotatable to any desired position of angular adjustment and may be locked in such selected position by release of the button 48.
By reference to Fig. 4, it will be noted that each of the cam elements 43 and 44 is provided with a conical or tapered surface 43a which is inclined at an angle of about 30 degrees to the axis of the pin 45, and also has a conical or tapered surface 43h which is inclined at an angle of about 10 degrees to the axis of the pin, the latter surface corresponding to the angle of inclination of the surfaces 4I, 42 of the members 40. In locking the head 5 to the shank 3, the initial action of the spring 46 causes the members 48 to be iirst engaged by the surfaces 43a, and, as these surfaces are at an abrupt angle of inclination, the
camming action will be relatively rapid. Thereafter, the surfaces 43h will engage the surfaces 4I and 42 and the movement of the members 40, due to the reduced inclination of the surfaces 43h, will be slower and more forceful, culminating in the desired wedging of the members 40 in head-locking position.
By using two inclinations, such as the surfaces 43a and 43h on the cam elements, it is possible to obtain rapid and satisfactory locking engagement while using a spring 46 which need not be as strong as would be the case otherwise.
In that form of the invention shown in Figs. 5 and 6, the general construction of the parts is similar to that previously described with reference to Figs. 1 4, but in this case, the splined members 3D which correspond to the members 40 of the previously described form of invention, are provided with only a single inclined surface 3| intermediate their ends.
The surfaces 3l are engaged by a conical cam element 32 which is carried by a pin 33 mounted for reciprocatory movement in the bore I2 of the portion I0 of the shank 3. The pin 33 has an enlarged end 34 which projects out of the bore I3 of the shank 3 and serves as a button for effecting release of the locking members 30.
A compression coil spring 35 is interposed between the abutment or shoulder I4 of the bore of the shank and a flange 31 on the pin 33 so as to normally urge the pin to the right, as viewed in Fig. 5. A gasket 38 is interposed between the ange 31 and the wall of bore I3 so as to provide a dust-proof and water-proof seal which will prevent foreign material from entering the bore I3.
In the position shown in Fig. 5, the members 38 have been cammed by the element 32 into engagement with the serrations 9 of the head 5, thereby locking the head 5 and shank 3 together.
When the button 34 is depressed, the pin 33 is caused to move to the left against the action of spring 35 and as the cam element 32 disengages the members 3i), the spring I9 retracts the members 35 so as to disengage the serrations I6 thereon from the serrations 9. The head 5 may now be rotated to any desired position of angularity relative to the shank 3.
After the selected p-osition of the head has been obtained, the pin is released and spring 35 causes element 32 to again cam the members 3 into the previously described head-locking engagement.
Referring to Figs. 1 and 8, the construction therein shown is similar to that of Fig. 5, but in this case, the cam element 10 which corresponds to the cam element 32 is in the form of a nut which is threadedly secured to a pin 1I, so as to permit adjustment between the inclined cam surface 12 of the nut and the inclined surface 13 of head-locking members 14 to compensate Ifor the wear on these surfaces.
The members 14 have a serrated surface I5 which is adapted to engage the serrations 9 on the head 5. The ends of the members 14 opposite the surface 13 are inclined or sloped in the opposite direction to form surfaces 84 which engage correspondingly inclined surfaces 85 formed on the shank 85 and which act to cam the members 14 to head-locking position.
The pin 1I is` provided with an enlarged head portion 15 which has an inclined end surface 16 which is engaged by the correspondingly inclined end 11 of a pin 18 which is mounted for reciprocatory sliding movement in the shank 86 of the hosel 19. The pin 18 is engaged at its upper end by a lever or trigger element which is pivotally secured to the hcsel as by a pivot pin 8|.
It will be apparent that when the trigger element 80 is depressed toward the hosel 19, the pin 18 is moved downwardly against the tension of a compression coil spring B2 which is interposed between the shank 86 and the enlarged portion 15 of the pin 1I. This downward movement causes the pin 1I to be cammed to the left, as viewed in Fig. '1, releasing the members 14 from camming engagement with the element 10.
The spring I9 which encircles the members 14 then retracts the members so that serrations I6 are withdrawn from engagement with serrations 9 on the head 5.
Upon release of the trigger element 80, the spring 82 acts to return the members M to locking position.
A screw cap 83 is provided to conceal the pin 'Il and prevent ingress of dust and dirt into the shank of the club.
Thus, in each of the forms of my invention which I have described, the head of the golf club is rmly locked to the shank by means yof serrated radially movable locking members which engage serrations on the head in response to the camming action of a spring-pressed cam element.
In each case, the head may be released for rotation to a different selected position of angular adjustment by displacing the spring-pressed cam element, which permits an annular spring to retract the locking members from engagement with the head.
It is thus seen that I have provided various adjustable head golf clubs having improved means for locking the club head in adjusted position as Well as improved means for eiecting the release of the club head for adjustment.
It is to be understood that the forms of my invention, herewith shown and described, are to be taken as preferred examples of the same, and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of my invention, or the scope of the subioined claims.
Having thus described my invention, I claim:
