Specification of Letters Patent.

Patented Mar. 5, 1918.

Application filed September 28,1914,- Serial No. 863,819. Renewed October 27, 1917. Serial No. 198,899.

the following is a full, clear, and exact specification.

My invention is concerned with adjustable golf clubs of the type shown in the patent to Curry, No. 1,083,434, issued J anuary 4, 1914, and is designed to improve the club shown in the aforesaid patent in certain respects which make it much stronger and more durable, so that it will stand the violent blows incidental to its use without weak ening or loosening its parts.

With this object in view, I have invented a new form of locking mechanism, and changed the design of the interlocking channels, as will be hereinafter specified.

To illustrate my invention, I annex hereto asheet of drawings, in which the same reference characters are used to designate identical parts in all the figures,.of which,

Figure 1 is a rear elevation of a club embodying my invention, with a portion of the shank and blade in central longitudinal section;

Fig. 2 is a side elevation of the same, with a portion of the shank and the controlling co lar broken away;

Figs. 3, 4 and 5 are a rear elevation, an end elevation, and a top plan view, respectively, of the blade detached;

Fig. 6 is a perspective view of the locking in;

Fig. 7 is a longitudinal section upon the line A-A of Fig. 1;

Fig. 8 is a perspective view of a strengthening block which I may employ; and

Fig. 9 is a detail showing the tip that may be substituted for the blade when it is desired to carry the shaft as a walking stick.

In carrying out my invention, the customary wooden shaft 10 is employed, and is fitted in the customary manner in the upper end of the upper ortion of the shank member, which is pre erably made of two parts 11 and 12. The part 11 has the customary recess 12 to receive the reduced end 13 of the shaft in the customary manner, and it has a recess 14 in its lower end which is interiorly threaded with a left-hand screw, so that when the threaded upper end 15 of the lower portion 12 of the shank is screwed in place,

any blow given to the blade connected to the lower portion 12 of the shank will tend to tighten the two portions, rather than to loosen them. The upper end 15 of the portion 12 abuts squarely against the bottom of the recess 14 so as to prevent the locking collar 16 from being cramped between the shoulder 17 formed on the lower portion 12 of the shank and the bottom of the upper portion 11 when the parts are screwed together. The upper portion of the lower part 12 of the shank has a slot 18 out therein, so that the threaded lug 19 projecting from the upper end of the lockingpin 20 may slide in said slot 18 and have its threads cooperate with the internal threads of the collar 16, the outer surface of which is preferably milled so that it can be readily turned. The body of the locking pin 20, with its tapered lower end 21, extends through the cylindrical opening 22 formed in the lower portion of the lower part 12 of the shank, the aperture 22 being concentric with the axis of the shank. As in the structure of the above-mentioned Curry patent, the tapered lower end 21 of the locking pin 20 cooperates with the desired one of the corresponding plurality of recesses 23 formed in the thickened end 24 of the blade 25. By turning the collar 16, it will be readily seen that the threads on the inner surface thereof cooperating with the threads on the projection 19 will raise and lower the locking pin into and out of locking engagement with the recesses 23, and it will befurther noted that when the pin is thrust down into locking engagement, it is held there positively, and does not depend on any sprin action, and is not liable to be thrown out o engagement by the impact of the blade on the ball in making the stroke. or upon the ground in case the stroke is dubbed.

The lower end of the lower portion 12 of the shank is provided with an extension 26 'which has a bearing aperture 27 therein,

nel 31, which is bounded by the segmental flange 32 on its upper side and the blade has the cooperating segmental flange 33, in which are located the recesses 23, which flange extend into the channel 31, and the blade is also provided with the channel 34 cooperating with the flange 32 of the shank. It will be noted that the sides of these two flanges and channels are at right angles to thebearing screw 28, instead of being parallel to the axis of the shaft 10, as in the above-mentioned Curry patent. This is an important feature of my invention, inasmuch as the angles of the sides of the channels in the Curry club are such as not to oppose the tendency of the blows to draw the channels and flanges apart from each other, assuming. that the blade tends to swlng about an axis at right angles to the axis of the screw 28 and through its head. With the sides of the flanges and channels set as in my invention, there is an interlockingaction that tends to prevent such a separatlon, and thus strengthens the club and results in its being decidedly more durable in the Severe usage to which it is subjected.

As a means -of strengthening the upper portion of the lower part 12 of the shank, I may place the rectangular block'35, of steel or some other hard metal, in the groove 18 above the top of the locking pin 20. This fits snugly in the channeland .holds the threads expanded and in engagement with the threadsjn the upper part 11 of the shank, and also prevents the locking pin 20 from being raised farther than is necessary to unlock the parts.

If it is desired to carry the club and use it as a walking stick, the shaft 10 may be turned, when the upper portion 11 will be unscrewed from the lowerportion 12, and a tip 36 provided with a threaded upper portion 37 may be screwed into the lower end of the portion 12 of the shank, and thus transform the shaft into a walking stick.

While I have shown and described my invention as embodied in the form which I at present consider best adapted to carry out its purposes, it will be understood that it is capable of modifications, and that I do not desire to be limited in the interpretation of the following claims except as may be neces-.

sitated by the state of the art.

What I claim as new, and desire to secure by Letters Patent of the United States, is:
