Patented Oct. 1, 1935 UNITED STATES PATENT OFFIE GOLF CLUB Application August 24, 1929, Serial No. 388,069

11 Claims.

My invention relates to golf clubs and relates particularly to improvements in the method of and means for joining golf club shafts to golf club heads.

An object of my invention is to provide a novel method by which a golf club head may be secured to a golf club shaft which may be metallic and tubular, whereby vibrations otherwise transmitted at the moment of impact of the head with a golf ball to the handle end of the shaft, may be considerably subdued.

Another object of my invention is to provide an improved method of securing golf club shafts to golf club heads.

Another object of my invention is to provide for a relatively inexpensive but highly eiiicient method of securing golf club heads on to the end of the shafts.

Another object of my invention is to provide for the attainment of any and/or all of the foregoing objects in a structure which may be particularly applicable to the securing of metallic heads to tubular metal shafts, and which will subdue the shock due to impact of the club head with a ball, and which would otherwise be undesirably transmitted to the handle of the shaft.

Other objects of my invention and the invention itself will become apparent by reference to "the following description of an embodiment of 30 y invention, reference therein being had to the a o panying drawing illustrating the said embodimentfx Referring to the drawing:

Fig. 1 is a side elevational view of the lower end portion of a golf "club m tall c h a and the lower end of a metallic tuhularcshaft secured thereto.

Fig. 2 is a view similar to that of Fig. 1 but the shaft and the hosel portion of the head shown in longitudinal medial section.

Referring now to both of the figures of drawing, the club head i illustrated is of the so-called iron type, which type includes such clubs as driving-irons, mid-irons, mid-mashies, mashies, spade-mashies, mashie-niblicks, niblicks and putters.

Although my invention is not limited to use in connection with irons, very advantageous results are secured in connection with such use, since the shock of impact imparted to the striking face of a golf club, is more violently transmitted in the case of such clubs than in the case of clubs having wood heads. Such irons comprise the lowermost striking portion 2, provided with a forward striking face shown in the drawing as being ribbed, and an upstanding tubular portion 3 formed integrally therewith.

The tubular portion 3 when employed in connection with wood shafts such as those made of hickory, has its interior recess tapered so that 5. its diameter is less proceeding toward the end of the recess shown at 4.

The golf club shaft 5 of the embodiment illustrated, is of tubular form and is preferably of that form illustrated and described in United 10 States Letters Patent No. 1,670,530, dated May 22, 1928, to Robert H. Cowdery, and comprises preferably a plurality of integral cylindrical tempered steel sections, each of successively decreased diameter proceeding from the handle end of the 15 shaft toward the club head supporting end, although my invention may be advantageously employed in connection with shafts of other types and other forms.

The shaft it may, therefore, be provided with 0 a plurality of tubular sections 6, 1, 8, etc., each of successively larger diameters proceeding in the direction of the handle of the shaft, the sections 6, 1 and 8 being preferably also of shorter length slap the sections !5 and it located at the lower .5 or club head end of the shaft.

The section l5 being of greater length than the sections 6, 1 and 8 and of lesser diameter, provides a resilient snap action adjacent the head which is greater when a ball is struck than would be the 0w. case were all of the sections made shorter than are the sections 6 and 1. Also I preferably make the end section It of tapered form so that its lowermost end 2| is of lesser diameter than its uppermost portion 18; there being, however, a sub- 5 stantial and more or less abrupt increase in diameter proceeding from the portion iii of the section l6 to the elongated preferably cylindrical section !5 disposed immediately above it, to provide a shoulder 9 between the sections I5 and I6. 9

A tubular bushing III, which is tapered in both directions from an intermediate part H, is forced into the tapered recess 4.01? the club head hosel 3 to a predetermined depth suificient to effect a. very tight wedging fit between the bushing and the interior walls of the hosel.

The intermediate bushing portion I l of greatest diameter is then preferably disposed imimmediately at the upper end l2 of the tubular walls of the hosel 3. The bore of the bushing is adapted to receive the section it of the shaft, forced therein; but prior to such forcing of the section it into the bore of the bushing I 0, a tubular tapered metal ferrule I3 is telescoped onto the lower end 2! of the shaft section I6 until its smaller end i l engages the shoulder 9 joining the shaft sections l5 and It, said shoulder preventing further telescoping of the ferrule upwardly on to the shaft.

The bushing it being of double tapered form, comprises an upper short tubular section I1 and a'relatively long section 19 driven into the hosel. The shaft with the ferrule i3 carried thereon is forced into the bushing iii preferably until the ferrule i3 is snugly, longitudinally compressed between the shoulder 9 of the shaft and the circular edge I 2 at the upper end of the tubular hosel.

The hosel bushing and shaftsection I6 is then transversely bored to admit a rivet pin 29 projected through the transverse bore, and headed over at both ends to prevent relative rotative and longitudinal movement between the secured parts, comprising the shaft, bushing and hosel.

The, ferrule fitting so closely against the hosel end, then appears exteriorly as an upward tapered projection of the shaft, and provides such a merging of exterior surfaces of shaft and hosel as to give somewhat the same impression as would be given were the shaft, ferrule and hosel all construc'ted in one piece, with slightly curved annularlines surrounding the joints between the named portions.

The ferrule is formed of resilient metal and furnishes a slightly yieldable reenforcement for the lower reduced end of the shaft immediately adjacent the hosel, and as does also the bushing I0.

The bushing l may be made of various materials but I find that wood makes a very acceptable material for joining iron heads to steel tubular shafts.

Having thus described my invention in a particular embodiment, I am aware that numerous and extensive departures may be made from the embodiment herein illustrated and described but without departing from the principles of my invention.
