This invention relates to golf clubs and has for an object the provision of a club wherein the head may be angularly adjusted, so that the same club may be used for plays .5 ordinarily requiring different clubs, such as a driver or brassie.
Another object of the invention is to provide a club with a head which may he quickly and angularly adjusted and securely held in l@ adjusted position.
Another object of the invention is the provision of a club which in addition to the above and other advantageous features, is simple in construction and efcient and reliable in use.
With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and 519 pointed out in the appended claims.
In the drawings Figure 1 is an elevation of a golf club constructed inaccordance with the invention.
Figure 2 is a fragmentary sectional view showing a golf club constructed in accordance with the invention with the head locked to the shaft.
Figure 3 is a like view with the head released.
Figures 4 and 5 are sectional views taken respectively on the lines 4-4 and 55 of Figure 3. n
Figure 6 is a fragmentary view of one end of the shaft.
Figure 7 is an edge view of the head.v
Referring to the drawings in detail Wherein like characters of reference denote correspending parts, the reference character 10 indicates the shaft of the club which is tapered from the handle downward. The shaftis hollow and has secured over one end a hollow shank 11 to which is detachably secured the head 12, the manner of attachment being hereinafter explained.
Extending from the shank 11 and preferably threadedly secured therein as shown at 13, is a sleeve 14 and this sleeve extends into a socket. 15 provided in the head. Secured within the socket 15 is one end of a steel 50 bushing 16 and secured withinthis bushing `is one endof the flexible section 17 `of a steel rod 18. 'This rod extends upwardly through the hollow shank 10 and Yhasslidingly secured to its upper end by means of a key 19, a sleeve'20 whose outer end isprovided with 55 a knurled flange 21. This flange defines a `shoulder 22 which engages the upper end of the hollow'shaft 10.
In order to connect the steel shaft 18 with the section 17, the `former is provided with a reduced extension 23 which is secured within a steel bushing 24 and this bushing is secured to the extension 23 by means of pins 25.
It will be seen that by means of the knurled flange 21, the shaft 18 may be rotated and this (65 rotation will' adjust the, head 12 angular-ly when the head is released. In order to hold the head against rotary'movement, the head is provided at its inner end with radially disposed teeth or serrations 26 which detac ably engage similar-teeth or serrations 27 which are disposed radially aboutthe adjacent end of the shank. r
Secured within the shank 10 as shown at 28 is a collar 29 while secured to the rod 18 i"7'5 within the shank 10v as shown at 30 is acollar 31. These collars have their adjacent ends serrated or toothed as shown at 32 so that when these teeth are engaged relative rotary movementk between the shank 10 and the rod 18 will be prevented;
Y Also secured within the shank 10 as shown at 33 is a collar 34, and a spring 35 which surrounds the rod 18-has one end bearing against this collar. The opposite end of the spring bears against a collar 36 which is secured tothe rod 18 as shown at 37, so that the tension of this spring is toforce the rod downwardly to disengage the head from the VShank 11 and disengage the collars 29 and 31.
The Vouter end of the rod 18fis threaded and mounted upon this end of the rod is an internally threaded socketed cap 38.
By loosening this cap 38 the spring 35 will force the rod 18 downward so asto disengage the collars 29 and 31 and disengage the head 12 from the shank 11. When the parts are thus disengaged, the rod 18 may be rotated through the medium of the knurled flange 21 so as to angularly adjust the head. After 100 Fee feo
proper adjustment has been obtained, the rod 18 may be drawn upward by screwing downward upon the cap 38. Engagement of the teeth or serrations 26 and 27 of the 5 shank 11 and head 12 respectively will prevent any rotary movement of the head, while engagement between the teeth of the collars 29 and 31 will prevent rotary movement between the shank and rod and assist in holding the head in adjusted position.
The invention is lsusceptible of various changes in its form, proportions .and minor details of construction and the right is herein reserved to make such changes .as properly fall within the scope of the appended claims.
Having described the invention what is claimed is 1- 1. In an adjustable golf club, ya hollow shaft, a head having a socket therein, a
m sleeve secured to and extending 'from one yend of the shaft into the socket to rotatably connect the head and shaft, a rod including a flexible section having one end secured to the head and extending through said ysleeve and shaft, means at the 4other end of the rod by which the latter may be rotated 'to adjust the head angul-arly, with respect to the shaft axis, and `means providing a `detachable interlocking engagement between the head and shaft to prevent rotation of the rod.
2. In an adjustable golf club, a hollow shaft, a head having a socket therein, a sleeve secured to and extending from one end of the shaft into the socket to rotatably connect the head and shaft, arod vincluding a flexible section having one end secured to the head and extending through said sleeve and shaft, means at the other end of the rod by which the latter may be rotated to adjust the head o angularly with respect to the shaft axis,
means to move the rod longitudinally of the shaft, and means controlled by such movement to provide a detachable interlocking engagement between the head and shaft to prevent rotation ofthe rod.
3. In an adjustable golf club a hollow shaft, a head, a rod extending through the hollow shaft'and having one end secured to the head, means engageable with the other end of the rod by which the latter may be rotated to adjust the head angular-ly with respect to the shaft axis, and means to provide a detachable interlocking engagement between the head and shaft.`
In testimony whereof I aflix my signature.
