This invention relates to golf clubs and has as its primary object the provision of means foi detachably connecting the head of the club tc the handle, so. that various kinds of heads can be used with one handle.
The invention together with its numerous objects and advantages will be best understood from a study of the following description, taken in connection with the accompanying drawing wherein is illustrated a preferred embodiment of the invention.
It is to be understood at the outset that it is in no wise intended to restrict the invention to the precise details of construction, combination and arrangement of elements as here specifically illustrated and described, other than may be necessary to meet the requirements of the prior art and scope of the appended claims.
In the drawing: Figure 1 is a view of the lower part of the golf club constructed in accordance with the present invention.
Figure 2 is a sectional view for illustrating details of the joint to be hereinafter more fully referred to.
Figure 3 is a view of the lower part of the handle.
Figures 4 and 5 are transverse sectional views taken substantially on the lines 4-4 and 5-5 respectively of Figure 2.
Figure 6 is a view of the head and stem associated therewith, and Figure 7 is a fragmentary vertical sectional view through a sleeve.
Referring to the drawing by reference numerals the letter A indicates a portion of a handle and letter B indicates the head of the club, the shank or stem I of which is formed with a socket 2 to receive the reduced part 3 of the handle. On the reduced part 3 of the handle is a shoulder 4 and above the shoulder is a groove 5 in which is arranged a coil spring 6. On the reduced end 3 of the handle there is also provided a spiral thread 7 which merges with the shoulder 4.
On the inner wall of the socket 2 there is provided a complemental spiral thread 8 to cooperate with the thread 7 when the part 3 is placed in the socket and one of the parts is rotated relative to the other part for screwing the end 3 down into the socket until the shoulder 4 abuts the upper end of the stem 1.
Slidably mounted on the lower end of the handle A is a locking sleeve 9 that is provided at its lower end with an inwardly facing elongated lug s having an upper part 10 normally engaging a notch II in the shoulder 4 and a lower part 12 to engage a notch 13 formed in the wall of the L socket 2 when the head has been screwed onto the handle A and notch 13 brought in registry with the notch I .
The spring 6 has its lower end engaging the upper part 10 of the lug carried by the sleeve 9 for normally urging the sleeve downwardly or in the direction of the head B to engage the lower end 12 of the lug with the notch 13 to prevent rotation of the head B relative to the handle A.
By forcing the sleeve 9 upwardly against the action of spring 6 the lower part 12 of the lug is moved out of engagement with the. notch 13 and the head B can be rotated relative to the handle A to thereby detach from the handle and another head substituted therefor.
To prevent the sleeve being forced entirely off the end of the handle by action of the spring 6 there is provided on the handle A a shoulder 14 while the upper end of the sleeve 15 is turned inwardly as at 15 to engage the shoulder 14 in a manner clearly shown in Figure 2. To facilitate shifting of sleeve 9, the same may if desired, have the exterior surface thereof knurled or otherwise formed to provide a roughened surface.
Having thus described my invention, what I claim as new is: 1. Means for connecting one member to another comprising a socket in one member and a reduced portion on the other member for entering the socket, the reduced portion on the said other member being provided with a spiral thread, and said socket being provided with an internal spiral thread complemental to the thread on said reduced portion for threadedly securing said reduced portion within the socket, and locking means for securing the parts together, said locking means including a sleeve slidable on said other member, a lug on said sleeve to engage alined notches provided one on the wall of the socket at the upper end of the socket, and a second notch on the reduced portion of said other member, said other member above said reduced portion being provided with a groove, a spring arranged in said groove with an end position to be engaged by the lug on the sleeve for normally urging the sleeve in one direction to retain said lug engaged with the alined notches. 2. In a golf club, the combination with a shaft, a head, said shaft having a reduced end, and said head having a socket receiving the reduced end of the shaft, and inter-engaging means on the socket and reduced end of the shaft for holding the head and shaft assembled against axial separation, of a sleeve slidably mounted on said shaft, said shaft and said socket being also provided with notches and said sleeve being provided at one end with a lug engageable with the notches whereby relative rotation between the shaft, socket and sleeve is positively prevented, and resilient means housed within said sleeve and having bearing engagement with said shaft and one end of said lug for normally urging the sleeve longitudinally of the shaft and in the direction of the head and thereby resiliently retain said lug engaged with said notches.
3. A golf club having in combination a shaft having a reduced end portion, and a circumferential groove adjacent said end and a notch at the junction of said reduced end portion and said groove, a head having a socket adapted to receive the reduced end of said shaft, said reduced end of the shaft being externally threaded, and said socket being internally threaded complemental to the thread on said reduced end of the shaft, said head at the open end of the socket being also provided with a notch adapted to aline with the first named notch, a locking sleeve slidably mounted on the shaft and provided with a lug adapted to engage the notches whereby relative rotation between the shaft and head is positively prevented, said lug having an end terminating internally of said sleeve, and a coil spring arranged within said groove and having an end portion engaging the inner end of said lug for yieldably retaining said lug engaged with said notches.
