This invention relates to golfdubs; and more particularly to agolf club havinga head; the striking angle of which is adjustable from thegrip end of the handle.

Golfclubs are generally provided in sets; the metal blades'of individualclubs varying in angle,

so:.that by selection of one oranother'club of 'the" set. varying driving" effects upon the ballimay' be had.

The object of this inventionisv to provide'a:

single' club having a blade adjustablewith'refe erence to the-axis ofethehandle'so that the blade".- can be set at any: angle withintherangeofangles generally suppliedbysa' set. of. clubs, thus -rendering it unnecessary to employasetof clubs, each' havingablade permanently set at a different angle from-the others.

.Another object of the inventionis to provide the hollow handleof the club witha-stemaxially movable therewithin by a manual adjustmentat the grip end of the handle and'adapted to. be-

held at any set position.

of the club to turn therewith.

Another object of the invention is to provide agearingbetween the head. endof: the-stem and: the arbor-afiixed to the blade; to-rotateand-; hnld the blade in any angular "position to which' it" may "be set by axial movement of'the stem.

A further object of the inventionis to provide a rugged construction providing for the afore-' said adjustment, capable of withstanding the" stresses incident togolf clubs;

Th'ese'and other objects of the invention will be'illustrated in the 'drawings,1deseribedf in the specification and pointed out in the claims at the end thereof.

In the drawings; like reference numerals indi cate like parts.-

In the"- drawings, reference numeral I indicatesthe tubular "shaft .portion of the handle 'ofra golf cluband'l indicates a-stem that is'madeup of two' parts, which stem is enclosed -inthe handle and; moves endwise therein and is held againstrotatione therein as will presently be explained.

Enclosed'in theigrip end-of the tubular handle is a split sleeve 3 shown in Figs. 1 and 7,-whichsleeve is heldwagainst rotation in. the handle" I bys-twofipins4 and-5 which pins are-inserted in the 'tubularhandle I and engage; in holes in the sleeve' 3. Th'eserpins do not go-through thestem 22" Attheupper endythestem 2 isiprovided with a male'thread. On' the upper end of the-stem 2-" isrpl'aeed a cap 6; which is threaded witha'femalethread that engages withathe male threadpnthe upper end of thestem; Thiscap turnsfor the purpose of. moving" the": stem *endwise in a manner that will presently bedescribed.

The split sleeve-3has-amutilatedfiange at the topethereof. The-sleeve is split so that theupper ends of it can be sprung, together. The flange at. the --top is mutilated or I cut away to-form the small flanges 1 and 8'-as-shown= in Figs; 1, 5,- 6 and' 'i. The= capwis formed: with'an annulargroovet-9--with which the small flanges 1 and 8"- can engage'when the upper end of the split sleeve is: released" and the ends *are' allowed tospring. apart, 'it' being understood? that the upper ends of the split sleeve are 1 pressedtogether so that the mutilatedfianses can pass; through the narrow 3 opening below the annular groove 9 until they are in line with the groove itself and are then allowed to spring apart. This permits the cap to rotate freely on the flanges.

When the stem 2 is inserted in the split sleeve 3 the mutilated flanges l and 8 are held in spread relation and securely held in the annular groove 9 of the cap 6. On the lower end of the stem 2 is the enlarged cylindrical stem end member M. The end member M is provided with a socket into which the lower end of the stem 2 fits and the two parts are pinned by the pin Ma.

The split sleeve and the cap are first assembled in this manner and the upper end of the stem 2 is inserted into the opening of the bottom of the split sleeve 3, and makes threaded engagement with the cap 6. The stem and its assembly are held against rotation in a manner that will presently be described and the stem and the assembly are moved endwise by turning th cap 6.

On the lower end of the shaft portion of the handle I of the golf club is provided a casting i8, which has a bore therein aligned with the handle axis to receive the enlarged cylindrical end member 14 of the stem 2. The casting also has a horizontal bore therein to receive the arbor H3. The upper end of this casting is recessed to form a shoulder 20 on which the lower end of the handle shaft portion l rests. The parts are held together by a tight drive fit. They can be pinned together if needed. The casting comprises intersecting integral sleeves whose bore axes are askew to one another.

On the enlarged end member i4 is formed the teeth of the rack H. The enlarged end member is cylindrical and the crest of the teeth formed therein are therefore rounded. The arbor I9 is formed with gear teeth milled into it which when the arbor is inserted into place engage with the teeth of the rack as is shown in Figs. 3 and 4. The right hand end of the arbor is formed with a head 21. This arbor is inserted in the horizontal bore so that the rack and the gear teeth mesh with each other. On the left hand end of the arbor is placed the blade 22, which blade has a boss 24 on the back of it, which is recessed with a hole to receive the left hand end of the arbor 19, it being understood that the arbor and the blade are pinned together as indicated by the pin 23. The back of the blade is also reinforced by the ribs 25, 25.

The stem with the assembly at the upper end thereof, as above described, with the enlarged end member Id at the lower end is inserted in the grip end of the handle with a washer il interposed between the lower end of the cap 6 and the top of the handle shaft portion I, it being understood that the arbor I9 is first inserted in the horizontal hole in the casting I8. This brings the rack and gear shown in Figs. 3 and 4 in engagement with each other.

The teeth on the rack mesh with the teeth on the arbor and keep the stem 2 from rotating and limit it to an up and down movement.

The blade 22 is then placed on the arbor and is fastened to it by the pin 23.

Before the blade is placed on the arbor, the stem 2 and the rack I! should be brought to the lower end of its movement against the set screw 26, which set screw is shown at the bottom of Fig. 4. This is done by turning thecap 6. In this position the flat side 22a of the blade 22 is set at its maximum angle to the handle which is preferably about (15 degrees) 15 below the horizontal which horizontal is determined by a line 4 perpendicular to the handle. This position is indicated by the dotted line shown in Fig. 8. The blade is then placed on the arbor at this angle and is pinned to the arbor. Thereafter the cap is turned in the reverse direction to draw the stem 2 up until the fiat side of the blade 22 stands parallel to the handle. The further upward movement of the stem is then limited by inserting a set screw 21 in the cap 6. In this way the endwise movement of the stem is limited by the set screw 21 at the top and the set screw 26 at the bottom. By the rotation of the cap 6 the blade can be turned through an angle of about (75 degrees) 75 and left at any angle in between these limits and is held securely in such position.

In this way, the endwise movement of the stem is limited to about or of an inch.

By this adjustment of the blade, on club can be made to serve the same purpose as a number of clubs.

The upper end of the tubular handle shaft portion I is surrounded by a sleeve or a wrapping 30 for the purpose of forming a grip.
