CHARLES N. CURRY, OF CHICAGO, ILLINOIS, ASSIGNOR OF TWENTY-FIVE ONE- HUNDREDTHS TO TIMER GOODBICH' AND TWENTY-FOUR ONE-HUNDREDTHS TO CHARLES EVANS, JR., BOTH OF CHICAGO, ILLINOIS.

GOLF-CLUB.

I Specification of Letters Patent.

Application filed April 25 1913. Serial No. 763,539.

T 0 all whom it may concern-.-

Be it known that I, CHARLES N. CURRY, a citizen of the United. States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Golf-Clubs, of which the following is a full, clear, and exact specification.

As is well known to .all players of the game, the main difference between the various'iron clubs used, such as the putter, midiron, mashie and niblick, resides in the angle at which the striking surface of the blade is presented to the ball when it is struck thereby, .and the object of my invention is to produce a single club, which, by adjusting t e angle at which the blade stands to the shank, can be used for any one of a plurality of clubs, such as those above enumerated.

To illustratemy invention, I annex hereto a sheet of drawings, in which the same referenoe characters are used to designate identical parts in all the'figures, of which,

Figure 1 is a side elevation of a club embodying my invention, a portion of which is in central longitudinal section; Fig. 2 is an end elevation of the same; Fig. 3 is 'a view of the other end of the blade detached; 4 is a side elevation of the blade de-, tached; Fi 5 is a top plan view of the blade detac ed; Fig. 6 is a sectional view through the shank and blade, on the line AA of Fig. 1; and Fig. 7 is a view similar to a portion of Fig. 2, showing a modification of the means employed for holding the plunger in place.

In carrying out my invention, the customary haft a is secured in the upper end of the shank b in the customary manner. Instead of having the shank b integral with the blade 0, as is the customary practice, I make them separate and provide the following connections for adjusting the angle at which the blade shall stand.

The shank b has bored through the axis thereof a tubular passage d adapted to receive the plunger 6, which is preferably spring-pressed in place by a helically-coiled expanding spring f which is held in position by a screw-head g threaded into the upper end of the tubular passage d. As seen, the lower end of the plunger is preferably tapered slightly and is adapted to cooperate with any one of the four apertures h which are formed in a segmental flange a on the end of the blade, which flange is concentric with a bearing 7' which extends through a bearing aperture 70 in the lower end of the shank. 'A screw 1 is threaded into the end of the blade, through the bearing 7', and is locked in place by a set-screwm which is screwed into the bottom of the blade at right angles to the body of the screw Z. It will be observed that the screw 1 cooperating with the shank serves to prevent any movement of the blade relative to the shank except the movement of rotation heretofore described. The end' of the shank b is preferably enlarged so as to form a segmental channel n in which the flange 2' fits snugly,

and the channel a. is of suflicient length so that the apertures k are covered in all adjustments of the blade to prevent dirt orother material entering the same. The end of the blade 0 has a segmental channel 0 cut therein, and the side of the channel at in the end of the shank forms an annular flange p which enters the channel 0. The cotiperation of the two channels and flanges thus formed on the shank and blade further serves to hold the two parts against an possible relative movement exce t that o rotation of the blade 0 about the earing 7'. The blade is held in the adjusted position against rotation by the plunger e, and to provide for the ready adjustment of the club, the.

plunger is provided with a pin 9 which extends through an elongated slot 7' formed in the shank, and I also provide a shield or cover .s'associated with the head of the pin 9 and serving to cover the slot r in all positions, so as to prevent dirt getting into the passage for the plunger. As shown, I preferably make the heel of the blade a curved,

so that the club may be used withthe shaft a at difi'erent angles to the vertical.

Instead of employing the spiing f to hold the plunger 6 in its locking position, I may employ the L-shaped slot r shown in Fig. 7, and when the position of the club is to be changed, the pin 9 is turned out of the horizontal portion of the slot 1* into the vertical portion, and then raised until the blade is released for the new adjustment, after which the plunger is shoved down into the chosen aperture, and the turned through the horizont portion of the pin g is then a nation with a shank, of a slidin slot r to lock the plunger in position. ll may employ both the spring 1 and the t.- shaped slot.

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 necessitated by the state of the prior art.

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

1. In an adjustable golf-club, the combination with a shank having a latch carried thereby sliding along the axis of the shaft and having its lower end tapered in a conical form, of a blade pivotally mounted in said shank and having a plurality of flaring conical recesses therein into any one of which the tapered end of the latch may eX tend and lit snugly to determine the angle of the blade relative to the shank, and means to hold the latch in the recess.

2. In an adjustable golf-club, the combiplunger therein extending along the axis of the shank, an l.-shaped slot in the shank, a pin extending through said slot and connected to the plunger, by which the latter may be raised or rotated on its axis as far as the slot will permit, and ablade pivotally mounted in said shank and having a plu-' rality of recesses therein with any one of which the plunger may coiiperate to determine the angle of the blade relative to the shank.

3. In an adjustable golf-club, the combiture set at an angle to the axis of the shaft naaaaa and having a segmental channel therein concentric with the bearing aperture, of a blade having a bearing in said aperture, and a segmental flange having recesses therein coiiperating with the channel in the shank, a plunger in the shank having its end adapted to enter any one of the recesses, and means for holding the plunger in the recess.

4. In an adjustable golf-club, the combination with a shank having a bearing aperture set at an angle to the axis of the shaft and having a segmental channel therein concentric with the bearing aperture, of a blade having a bearing in said aperture, and a segmental flange having recesses therein coiiperating with the channel in the shank, a plunger in the shank having its end adapted to enter any one of the recesses, and means for holding the plunger in the recess, the segmental channel being long enough to cover the recesses in any position of adjustment of the shank.

5. ln an adjustable goltclub, the combination with a shank having a bearing aperture set at an angle to the axis of the shaft and having a segmental channel therein concentric with the bearing aperture, of a blade having a bearing in said aperture and a segmental flange coiiperating with the channel in the shank, and means interposed between the shank and blade to lock the same in different relative positions.

In witness whereof I have hereunto set my hand and afixedimy seal, this twentysecond day of April, A. D. 1913.
