Application October 13, 1941, Serial No. 414,798

4 Claims. (Cl. 273-79) My invention relates to a golfv club which may be adjusted so that a player may need no other club for a complete game of golf.

Among the objects of my invention is to provide a single golf club thereby eliminating the fourteenor more different clubs heretofore used, and the bag for carrying the same. To provide a club adjustable for use in place of the fourteen clubs now makng 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 for lasting wear. To

create a club that will not rattle and unnerveV To provide a' of the head with dotted outline of various ad.

justments; Fig. 3 is a rear elevational view of the head of my golf club; Fig. 4 is a detailed sectional view on line 4 4 of Fig. 3; Fig. 5 is a it detailed sectional view shown in neutral position; Fig. 6 is a detailed sectional view on line 6-6 of Fig. 3; and Fig. 7 is an enlarged detailed sectional view on line 'l--l of Fig. 3.

The embodiment selected to illustrate my in- I` vention comprises a shaft I0 having a grip H Y attached adjacent its'upper end.

Surrounding the lower end of vthe shaft II) is a hosel I2. A pin I3 extends from the h osel rI2 into the shaft II). -I4 beyond which extends an integral reduced extension or spindle I5.

A head I6 is slidably and pivotally mounted on extension I5 by a pair of spaced hollow lugs I'l. 'I'he extension I5 is embedded `in a shallow depression I8 in the back of the head I E and extends substantially the entire rlength of the head.

The lugs I1 have serrations I9 on their inner portions to interengage with spaced serrated portions 20 on spindle I5.

The head I6 is slidable on spindle I5, and when the head is moved so that its serrated portions y 20 are not within lugs Il so as to interengage with serrations I9, the head is in neutral or ad- The hosel I2 Vhas a bend 3 justableposition. The head may then be pivoted on the spindle for the desired lifting anglefof the face 2l. The angle of the face may be approximately 9 to 11 degrees with respect to the shaft to function as a driver for driving, 14 to 16 degrees as a brassie for middle distance or fairway, 17 to 20 degrees as a spoon for sand traps, and parallel to the axis of the shaft as a putter for putting. In other words the angle may be adjusted from driver to putter and for any lofting angle therebetween. The head may alsobe turned so as to be cleaned face downward on the grass.

When the desired angle has been selected, the user slides the head outwardly with respect to the spindle, so that the serrated portions 20 'of the spindle interengage with the serrations I9 on lugs Il. The head is then in locked position, and remains there by its own inertia.

rWhen the user swings the club in play, the centrifugal force of the drive acts to hold the head I in its outermost locked position and prevents the head from sliding back on the spindle to neutral position. It takes deliberate and manual pressure b-y the user to move the head back to neutral position on the spindle.

In order to keep the head from rattling in desired fixed position and annoying the player during delicate shots, a spring compensator or adjustable tension member 22 is provided comprising a spring 23 having a curved semi-circular portion 24 extending over spindle I5 between spaced serrated portions 20, and a flat retaining portion 25 positioned against the back of head I6. A screw 2E extends through portion 25 into head I5 for adjusting the tension. This construction substantially takes up the play necessary for slidability of the head.

At the inner end portion of the spindle I5 the lenlarged hosel I2 forms a stop 27 against which the inner one of the lugs I1 strikes when the head is in neutral position.

The outer serrated portion 20 at its outer end 28 is peened over or enlarged so as to retain head I6 on spindle I5 and prevent the head from leaving the spindle.

HavingY thus described my invention, I claim:

l. 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 pair of spaced hollow lugs and a shallow depression in its back portion beginning at its inner edge and extending outwardly therefrom for substantially the entire length of said head, said head mounted on said spindle with said spindle lying within said depression and extending through said hollow lugs, said lugs having serrations in their hollow interior portions, said spindle having equally spaced serrated portions, said head adapted to be slidably moved inwardly on sai-d spindle by manual pressure of the user until the serrations on the lugs are free from engagement with the serrated portions on the spindlev for neutral position, said head in said neutral position adapted to be pivoted on said spindle by manual pressure of the user to desired lofting angles, said head then adapted to be slidably moved outwardly on said spindle by manual pressure of the user for engagement of the serrated portions of said spindle with the serrations of said lugs to lock the head at the desired lofting angles, and a spring having a.

iiat portion lying on said head, a screw extending through said flat portion into said head, said spring having a curved portion extending across and bearing against said spindle between said serrated portions to prevent rattling of said head on said spindle in locked position.
