GOLF CLUB.

Application filed October 14, 1926. Berta! In. 141,844.

My invention relates to golf clubs, more part1cularl to means 0f securing the shafts 01 golf clu%s to the heads thereof.

In golf lubs now in use, the shafts are 5 made of wood as well as of steel tubing.

Although the golf Clubs with wooden handles rovide great6r flexibility and resiliency 0th longitudinally and torsionally, the same break frequently at the portions di- 10 rectly secured to the lwads. Steel 0r other metal shafts, although more durable, also break frequently at the portions secured 120 the heads. Steel o1 other metal shafts, as heretofore constructed, provide less longitudinal flexibility than W0oden shafts and very little torsional flexibility und resilienc 1%1e objects of my present invention am: first. t0 provicle a sbeel shaft for golf clubs which will have the torsional flexibility and resiliency 0f the wooden shaft of golf clubs and still h:we durability superior to the conventional steel shaft; second, tq provide a golf club having a steel shaft in Which the shaft is secured als its extreme end to the head of the Club and reinforced intermediate its ends near its secured end in the form of a pivot means adapted t0 take the initial bending moment und considerably relieve the danger of breaking 0f the shaft from the head immecliately at fhe secured portion; third, to provide a shaft f0r golf clubs whi'ch is provided intermediate its ends with longitudinal slots for weakening the shaft ab one portion t0 permit greater flexibility in twisting and longitudinal bending, a.s well as' to provide greater torsional and longitudinal resiliency; fourth, to provide a golf club having a, long ferrule provided 40 with a recesserl portion at its interior und intermediate its ende. und a fulcrum or bearing portion in its interior and outwardly from the recessed portion, tl1e shaft of the club extending through the ferrule and securecl t0 the head at the base of the ferrule, the fulcrum 0r bearin portion providing minforcement for sai shaft und fulcrum means for longitudinal bending, and said recessed portion providing clearance for the bent shaft within the ferrule; fifth,

to provide novel, elficient and economical means for repairing old golf clubs und transformin old clubs inbo new b merely cutting ofi' t e shank from the old ead und welding, brazing, soldering or otherwise securing a special ferrule tlwreto; sixth, to provide a steel shaft which may be slotted longitudinally to any desired degree to provide any desired flexibility und resiliency; seventh, to provide a golf club of this dass whereby tlu= shock often' imparted through the shaft t0 the hands cf the player, will be reduced to a minimum; und, e1ghth, to provide as a whole a novel means 0f securin a shaft 170 the head of a golf club, provi ing a simple und efllcient club und one Which will nbt readily deteriorate or get out 0f Order.

With these andother objects in view, as will appear hereinafter, my invention consists of certain novel features of construction combination und arran ement of parts und portions, as will be ereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings und to the characters of reference thereon which for'm a art 0f this application in which:

igure 1 is a fragmentary side elevational view of the head end 0f a metal head golf Club, showing certain parts ai1d port1ons thereof broken away and in section to facilitate the illustration; Fig. 2 is a. transverse sectional view of the ferrule und sl xaft taken through 22 cf Fig. 1; Fig.'3 is an enlarged fragmentary sectional elevational view of a slightly modified form of securing the ferrule und shaft to the head of a golf club; und, Fig 4 is a fragmentarz sectional elevational view taken throu the 90 s ightly median line of the club, showing a. difierent means of construction.

Like charactefs'of reference refer similar parts und portions throughout the Several views of the drawings.

The golf clubs illustrated in Fi 1 und 3 of tl1e drawings show the clu reconstructed from conventional clubs. The head, indicated by 1 in Fig. 1, is provided in the conventional club W11;h an outwardly end of the shank und at the ofiset ortion B thereof, is positioned the base end f --portion at t the tubular ferrule 2. This ferrule 2 may be bra.zed soldered, o1 welded t0 the head member 1. 1

The ferrule 2 may be tapered to smaller dimensions toward its upper end to reduce weight und also provide for greater flexibility. The interior 0f the ferrule 2 is provided with a. bore 2*considerably larger than the diameter of the shaft 3 extending therethrough, said bore extending upwardly at s11bstantinllg 1 the same diameter as the ofi'set e upper end of the shank of the hea.d member. The upper end of the bore of the ferrule, indioated by 2", is considerably constricted and loosely engages the rod 0r shaft 3 Several inches from its lower end for reinforcing the shaft. Seid constricted ortion 2" of the bore 0f the ferrule is also rounded und tapers divergently oncurved lines toward the upper end of the ferrule, as shown. Thus, when the shaft 3 is bent, the same will bend about the ortion 2 which serves es a fulcrum and Will bend slightly, but uniformly, from its lower end to the fulcrum ortion 2*. The bte 2 permits cousidera le bending of the shaft The lower end of the shaft 3 may be variously secured to the head member in a central recess 1' in the shank thereof, such .as by pouring molten brass, 01' other metal into the hole in which %1 e sl11aft is positioned, a.s indicated by 4 in The shaft 3, shown in the drawings, is gnade of ta ered steel tubing and is pr'vi%;ad m 1ts Wal s at the portion positioned e tween the upper end of the shank 0f the head member and the constricted ortion of the ferrule with longitudinal slots 3. Said slots are adapted to weaken the shgnft at seid por ti0n to such an extent es to provide torsional flexibility to any desire'ad degree as well as to increase its longitudinal flexibility. By such slotting, the torsional und IOng1tndinal resiliency is also increased. Si1ch flexibility und res1liency may be varied by increasing or decreasing the number und size of the lon 'tudinal slots in the shafthe structure shown in Fig. 3 is substantially the same, as that illustrated in l, ex :ept that the upper end cf the shan o f the head member and the base rtion of the ferrule are beveled, as indicate res ectively 'by 1" and 2, so that the two meml?ers may be readily welded together und tothe inner end of tl1e shaft.

It will be here noted that insteed oi constructing the head member 1 and the fex'rule 2 in se arate pieces, as statd the same may be ma e integrally, if desired.

In Fig. 4 of the drawings, the head momber l and the ferrule 2 are shown as of integral construction With the space between T the large bore 2 und the shaft filled with lead, 0r other deadening material 5. It will be noted in this construction, the shaft 3 may be provided with its smallest diameter some distance from its inner end, as indicated by 3", so that the lead o1 other mate rial 5 may readily retain the shaft in position.

In Fig. 4 0f the drawings, the inner encl of the shaft may be secured, if desired, to the head member in any suitable manner, such es by the pouring of molten brass 4 around the inner end of the shaft within the inwardly gonvrging recess and througl1 a hole from the outside of the head member. It will be noted if the shaft 3 is secured to the head member at its inner end as stated, or by any other means, the lead m othenmetal or material 5 may be eliminated.

By either 0f the last mentioned constructions greater flexibility is obtained than by rigidly secnring the outer end of the ferrule to the shaft, as in conventional constrnction. Also, by the former construction, in which lead is used for securing the shaft within the ferrule, the shock is somewhat deadened by the lead 01' other maberial 5.

Though I have shown und described a particular construction, combination a.nd a1- mngement of arts and portions, and certain modificat1ons thereof, I du not wish to be limited to this particular construction, com

bination and arrangement, nor to the modifications, but desire to include in the scope of my invention the construction, combination und arrangement substantially a Set forth in the appended claims.

Havin thus described my invention, what I c a.im a.s new und desire to secure by Letters Patent is:
