Patented Sept. 4, 1945 UNHTED STATES PATENT OFFICE:v i f 2,384,333 GOLF CLUB John- L. Nilson, Chicago, lll.l Appueatienoetober 9, 1942, serial No. 461,645

` 1 Claim.y (o1. 273-79) My invention relates to a gol club which may be adjusted so that a player may need noy other club for a complete game of golf.

Among the objects of my invention is. toprovide a single golf club thereby eliminating the fourteen or more diiferent clubs heretofore used, and the bag for carrying the same. To produce a club adapted for use by either right or left handed players. To create a club having a plurality of faces, a multiplicity of lofting angles and a distribution o1" weight below the center line for increased percussion. To provide a club adjustable for u-se in place of the fourteen clubs now making up a golfers standard set of clubs. To supply an adjustable club so constructed as to be easily adjustable, sufficiently strong in adjusted position for heavy use and accurate play and of lasting wear. To create a Club that Will not rattle and unnerve the player during delicate shots. To provide a club resulting in great economies in an expensive game, and such other objects, advantages, and capabilities as will later more fully appear and which are inherently possessed by my invention.

While I have shown herein a preferred embodiment of my invention, yet I wish it understood that the same is susceptible of modification and change without departing from the spirit of my invention.

Referring to the drawing, Fig. l is an elevational view of my golf club; Fig. 2 is an end elevational view of the head with dotted lines showing various adjustments; Fig. 3 is an enlarged detailed sectional View on line 3-3 of Fig. l; Fig. 4 is a longitudinal sectional View on line 4 4 of Fig. 3; Fig. 5 is a longitudinal sectional view of my head partly mounted on the spindle; Fig. 6 is a detailed side elevational view of the spindle and Fig. 7 is a longitudinal sectional view of the head.

The embodiment selected to illustrate my invention comprises a shaft I9 having a grip II attached adjacent its upper end.

Surrounding the lower end of the shaft I3 is a hosel I2. A pin I3 extends from the hosel I2 into the shaft IQ. The hosel l2 has a bend I3 beyond which extends an integral extension or spindle I5.

A solid head i6 is slidably and rotatably mounted on extension I5, with extension I extending into bore 30 of head I6. The bore 30 extends substantially the entire length of the head I6.

The bore 30 has a plurality of serrated portions I9, spaced by a plurality of enlarged non serrated or neutral portions 3|. The serrated portions I9 are adapted to interengage With enlarged serrated portions 20 on spindle I 5. The plurality of serrated portions 2l) on spindle I5 are-spaced by a plurality of reduced non-serrated or neutral portions 32. I

Spindle I5 has a bore 33 to receive a portion of coiled spring 34. .The upper end of spring 34, extends beyond said spindle. When the head I6 is placed on spindle I5, the upper portion of spring 34 contacts projection or stop member 35 at the end of bore 3U.

The head I6 is slidable on spindle I5, and when the head is moved inwardly so that its serrated portions 3| are opposite non-serrated portions 32 of the spindle, the head is in neutral or adjustable position. The head may then be rotated on the spindle for the desired lofting angles of the races 36, 31 and 38. The angle may be adjusted from driver to putter and for any lofting angle therebetween. The head may also be turned so as to be cleaned face downward on the grass.

When the desired angle has been selected, the spring 34 slides the head outwardly with respect to the spindle, so that the serrated portions 20 of the spindle mesh with the serrated portions I9 of the head IB. The head is then in locked position. It takes deliberate and manual pressure by the user to move the head back inwardly against the spring 34 to neutral position on the spindle.

The inner end of the head I 6 has a pair of spaced screw threaded holes 39. A plate 30 extends between these holes and has openings 4I.

A pair of screws 42 extend through openings 4Iv and are threaded into holes 39. The plate extends across a portion of the inner end of bore 3G and prevents the passage therethrough of the enlarged serrated portions 2D, thereby holding spindle I5 within head I5.

Referring now particularly to my head I6, it will be noted that it is triangularly shaped in its preferred form. Face 3G is formed for a right hand driver. Face 3I is formed for a niblick and face 38 is formed for a left hand driver.

These respective faces are formed with relation to the other faces of the head, so that when any one of the faces of my club is chosen for the striking face, at substantially any angle, the greater portion of the weight of the club is below a line drawn across the center of the head. With the club in such a position the striking face of the head provides desired percussion in striking the ball. 'Ihe greatest efliciency is thus achieved, providing a solid hit. In those positions where one of the faces of my club is substantially parallel to the ground, the adjacent striking face provides maximum percussion in striking the ball.

While I have shown a triangular shaped club head, yet it is Within the contemplation of my invention that more sides may be added, furnishing additional faces.

My construction substantially eliminates the transmission of vibration through the shaft to the users hands, thereby preventing discomfort to the user and breakage of the shaft.

My construction also provides an adjustable head fitted so as to be water tight.

Having thus described my invention, I claim:

An adjustable golf club comprising a shaft, a hosel surrounding and attached to the lower end of said shaft, said hosel having a bend and integrally therebeyond a spindle, a head having a plurality of faces and a bore extending horizontally therethrough, said head rotatably and slidably mounted on said spindle with said spindle lying within said bore, a stop member positioned within the outer end of said bore, said spindle having an opening in its front end extending axially therein, a spring having its rear end extending within the opening of said spindle and with its front end contacting the inner end of said stop member, said spindle having a serrated portion at its outer end, and a plurality of spaced serrated portions throughout its length, the bore of said head having a plurality of similarly spaced serrations, said spindle having smaller spaced non-serrated portions between its said serrated portions and at its inner end, said bore having enlarged similarly spaced non-serrated portions between its said serrated portions and at its inner end, said head adapted to be slidably moved inwardly on said spindle by manual pressure of the user against said spring until the serrated portions of the bore of said head are opposite said non-serrated portions of said spindle for neutral position, said head in neutral position adapted to be rotated on said spindle to a desired lofting angle of any one of said faces, said head then adapted by said spring to be slidably moved outwardly on said spindle until the serrated portions of said spindle engage with the serrated portions of the bore of said head to lock the head at the desired lofting angle for the face chosen, so that said face may be used as a striking face, and means on the rear portion of said head positioned to engage the rearmost serrated portion of said spindle and prevent the accidental rearward withdrawal of said spindle from said head.

JOHN L. NILSON.
