Patented Oct. 31', 1944 UNITED STATES PATENT OFFICE GOLF CLUB Milton B. Reach, Springfield, Mass. Application June17, 1943, Serial No. 491,209 7 Claims. (01. 2 73-80) The present invention relates to golf clubs, and more particularly pertains to improvements in the club head and the shaft in golf clubs of the wood type.

One of the disadvantages of wood type golf clubs in the past is that the club often breaks in the hosel or neck area, and this weakness results from deficiencies in the structure of the joint between the club head and the shaft. In the past it has been customary to taper the neck or stem 50 as to blend o-r merge this part of the hosel artistically with the relatively small shaft. Such tapering of the hosel .portion leaves but a thin annular section of material around the shaft which provides an inherent weakness inconven- Another cause of the breakage in the hosel or neck area of such wood type clubs results from the torsional stresses set up during impact of the club head with the ball. .The club head in the vicinity of the relatively small stem is therefore subjected to considerable twisting action relative to the shaft and these forces are often sufiicient to-rupture the club head in the hosel portion whereby the club is no longer of further use. a s

It is accordingly an object of the present invention to provide an assembly of the club head and the shaft wherein the disadvantages of the prior constructions as hereinabove referred to are avoided.

Another object of the invention resides in providing a joint structure between the shaft and head of a golf club having an artistic appearance, and wherein the torsional stresses developed during, a tendency of the hosel portion of the club head to turn on the shaft are distributed over a relatively large part of the hosel.

A more specific object of the invention pertains to the provision of a transverse shoulder on the hosel or stem of a golf club head arranged at an angle to a plane perpendicular to the axis of the shaft including a flange on the shaft arranged substantially parallel to the oblique shoulder for preventing relative turning movement between the shaft and the'club head without setting up destructive stresses in the neck or hosel portion of theclub head.

A stillfurther object of. the invention resides in providing resilient material in the joint between the golf club head and the shaft to provide shock absorbing means in the joint and for the further purpose of sealing the connection between the club head and the shaft. I

Other objects and features of the invention will be more apparent upon consideration of the accompanying drawing and the following detailed description wherein anexemplary embodiment of theinvention is disclosed.

a In the drawing:

Figure 1 is a front elevational view of a club head of the wood type showing the initial step in shaping the hosel or stem.

Fig. 2 is a similar view illustrating the manner in which an oblique shoulder may be formed on the hosel portion of the club head. v

Fig. 3. is a side elevational view of a portion of the shaft illustrating the ferrule and flange thereon in section.

v Fig. 4 is a sectional view of the stem portion of the club head showing the manner in which the shaft and flange thereon are associated with the shoulder on the hosel. I

Fig. 5 is a side elevational view of the assembled shaft and club head illustrating the wrapping in section.

Fig. 6 is a sectional view illustrating a resilient member between the flange and the oblique shoulder on the stem of the club head.

In carrying out the invention, the clubhead indicated at ID in the drawing is formed in the usual conventional manner. Such a club head includes a stem or-hosel portion II which may be formed as an integral part of the club head ID. The hosel or stem I l is elongated and extends upwardly and angularly from the rear portion of the club head. When the club head is formed of wood the hosel or stem portion is usually conically tapered to such an extent that the neck blends or substantially merges with the shaft to which the club head is attached. This relatively thin poriton of the neck or stem provides a weak structure so that the stresses set up in the neck portion of the club during useare often sufiicient to .cause breakage orsplitting of the wood in the hosel portion of the club head.

The present invention provides means for strengthening'a golf club at the juncture between the clubhead and the shaft, and particularly in golf clubs of the wood type. The improved assembly is; such as toapply the torsional strains to the upperend of the hosel or stem portion without setting up material twisting stresses in the upper end of the stem on the club-head.

These advantages are obtained by shaping the.

upper end portion of the hosel so as to provide a substantial shoulder of material surrounding an opening l2 for the shaft. The shouldermay be formed by cutting off the thin conical tapered part of the stem in a manner as shown in-Fig. 1.

' The upper end portion ofthe hosel or stem ll relative 'movement between is however shaped to provide a plane surfac or shoulder l4 arranged obliquely to a plane perpendicular to the axis of the shaft or the opening l2 inthe hosel H. The angular relationship of the shoulder M with respect to the transverse shoulder is clearly illustrated in Fig. 2 wherein the substantially flat surface of the shoulder 14 is arranged at an acute angle tothe axis of the opening l2 in the hoscl or stem portion of the club head? The shoulder I4 thusforms the upper end surface of the hosel H and this annular shoulder surrounds the opening l2.

A shaft for the club head is shown at 15 in Fig. 3, and this shaft may be formed of any suitable material such as metal. The shaft is of a conventional design and is adapted to extend into the opening l2 arranged in thehosel ll club head In whereby the club head is mounted on the shaft.

Another feature of the invention pertains to the provision of aflang'e l'l on the shaft 15. The flange I I preferably embraces theshaft 5 to provide an annular shoulder thereon'complementary to the shoulder I4 at the upper'end of the stem or hosel .l l. The flange I1 isarranged in a' plane at" an'an gl'e to aplane perpendicular to the axis of the shaft I 5 Thus the flange I! is arranged at an acute'br obtuse angle withrespect to the axis of the shaft 15. The under face of the flange I] is preferably flat and arranged at such an angle on the shaft 15 so as to be parallel to the shoulder Mwhen the shaft is arranged in the opening i2. T his assembled relationship is illustrated in Fig. 4,

1 and it ll-be noted therefromgthat the shaft,

flange I! lies flat against the shoulder l4.

Theflange l1 may be secured to the shaft It: in any suitable manner. In'theexemplary embodiment illustrated in the drawing the flange l1 is'rigidly attached to the shaft by means of a tubular member IS. The flange I1 is preferably formed as an integral part of the tubular member or'sleeve I6, The tubular member may be secured to the shaft 1 5 in any suitable manner to prevent rotation of the sleeve on the shaft and to prevent axial movement of the tubular member IS on the shaft. j Thus the sleeve I 6 may be welded,br'azed or sweatedonthe shaft 15. 1

any conventional means such as a screw indicated at 18 i'nFig. 4. It will beobserved that the flange l'l'lies fiat against the shoulder 14' and the screw [8 is applied with the parts in this assembledpo'sition so that the flange I1 is retained against the shoulder 1 4 or the angular shaped end 'ofthestem orhosel H. Thus any tendency of the club head and thsh'a ft' i5'is prevented by reason of the angular relationship of the shoulder l4 and the flange 'lTwithre-spect to the axis of the shaft [5. Any tendency of relative turning movementbetween the club'head and the shaft [5 will set up a cam- Ining action between the flange 'l1 and the shoulder I4. Thus the forces tending to split the hosel portion of the club head are applied in a more or les'scompressional manner axially'of the hosel in contrast to torsional" stresses set up in a conventional type connection between the hosel and shaft of a golf club.

' The joint structure hereinabove described facilitates the finishing of the club whereby the appearance of the club'atthe connection between the club head and the shaft is artistic and provides a'slen'deriz'edblendingof the hosel and shaft.

Thus after the shaft has been affixed to the club lieadasshown and described in connection with and the.

ma ma l5 may be'retained within the open- Fig. 4, a wrapping may be applied around the tubular member 16 to form a slenderized cone tapering from the flange IT and merging with the shaft as shown in Fig. 5. The wrapping 19 may consist of any suitable material such as plastics and preferably extends above the upper end of the tubular member 16 so that substantially all structural features of the joint between the shaft and the club head are covered by the wrapping. The wrapping l9 may be'applie'd in excess of the necessary thickness, particularly at the base of the cone adjacent the flange I! after which the excess material may be rubbed down or otherwise removed to register with the lines of the neck portion of the club.

In some assemblies it may be desirable to interpose some yieldable or resilient material in the joint between the head and the shaft as a convenience in assembly, and to provide against shrinkage and to insure against open joints, and to ;add decorative color to the golf club. Thus a washer 20 may be arranged in the joint as shown in Fig. 6. This washer 20 may be applied simply by positioning the washer on the shoulder portion l4 belfzore introducing the shaft 15 into the opening over the lower end of the shaft l5 adjacent the flange ll before introducing the shaft into the opening of the hosel portion of the club head. The washer 20 may be made of some resilient material suchas rubber or some synthetic material to compress slightly under the camming action of the flange l1 relative to the shoulder l4 or'upper end portion of the hosel i I. The washer 20 will thus serve'a's a retarding agent and soften the shock to the hands of a player upon impact of the club head with the ball. The resilient washer 20 may be more desirable when the club head is formed of some material other than wood whereby the shock absorption of wood is no longer present in the club head material. The washer 20 also provides means for maintaining a closed joint between the flange ll and the upper end [4 of the hosel regardless of small shrinkages in the materials of the adjacent parts. The washer 20 may likewise be formed'of a material having a color in contrast to the adjacent parts of the club, and of a different color with respect to the other clubs, so'as to indicate different types of clubs.

While the invention has been described with reference to the specific structural details and with regard to various types'of materials in forming the jointure between the club head and shaft, it will be appreciated thatchanges in the structural features may be made and other materials may be employed in carrying out the invention. Such modifications and changes may be made without departing from the spirit and scope of the invention as defined in the appended claims.
