GOLF CLUB SHAFT Filed Sept. 8, 1931 Patented Apr. 19, 1932 UNITED STATES HERBERT C. LAGERBLADE, OE BRISTOL, CONNECTICUT GOLF CLUB SHAFT Application led September 8, 1,931. SeriaLNo. 561,747.

rIhis invention relates to improvements in golf clubs and particularly to golf club shafts.

During the course of a year, manufacturers of tubular golf shafts will accumulate thousands of pieces of steel shafts that are perfectly good except that they are too short for use as a golf shaft. Heretofore all of this material has been scrapped. This scrap material quite frequently runs as high as twentyfive inches in length. VThis is due to the fact that very often there is a slight imperfection in the steel that will cause a break in the shaft toward the upper end while the lower end is perfectly good and of high quality.

In order to eliminate this waste, the present invention contemplates a composite golf shaft in that the shaft is formed of tubular metallic material throughout a major por- '20 tion of its length, while its handle section is of wood.

A further object is to provide a satisfactory mode of attaching the wooden handle to a tubular metallic shaft body.

A still further object is to reinforce the connection between the wooden handle and steel shaft proper.

With these and other objects in view the invention consists in certain details of construction and combinations and arrangements of parts all as will hereinafter be more fully described and the novel features thereof particularly pointed out in the appended claims.

"w As stated, the present invention-seeks to render it possible to utilize sections of tubularmetallc material which, under previous practices, would be too short for use in a golf club shaft. Generally stated, this is accomplished by having the major portion of `the shaft formed of a tubular metalic member to which is attached a Wooden handle section, the length of the two elements aggregating the desired club length. Not only does such an arrangement permit the use of otherwise 3E scrap material but the provision of the woodenhandle lends to the nished club a feel, different from that of a club having a metallic handle portion. That is, many players do not like the feel of a steelshaft under the grip portion of the club, claiming that it is too hard while others claim that they receive a shock when hitting a ball with the club, due to the steel shaft. In a composite shaft such as now proposed the woodenhandle section imparts to the shaft the desired feel, and, in addition, any shock `such as complained of is also eliminated. This is believed to be due to the fact that the wooden` handle section has certain torsioning properties.

In carrying out the invention the shaft is composed primarily of the tubular metallic section 10 that extends the major portion of the length of the shaft and a wooden handle section l1. Preferably, .section l0 is a tapering cross-section, the .wooden handle sect-ion being attached to its larger end and the club lhead l2 attached to itssmaller end. The'tubular metallic section 10 will varyin length in different clubs, depending upon thel length of the scrap material being utilized or upon the length that is desired inthe finished article.

It has been a difcult matter to provide a "i joint between a metallic section and a wooden section in a golf club that will have the desired strength to withstand the strains placed upon it when the club is in use. These difficulties are overcome in the present instance T by having the wooden handle section l1 formed with a tenon 13, `preferablytapered .and wedged in the large end lof the :metallic section 10.. Immediately beyond the larger end of :the metallic section endthe handle 11 l l ui Y Y handle.

is surrounded by a metallic sleeve 14 and this sleeve overlaps the larger end of the metallic section of the shaft. This sleeve, and that portion of the handle which is engaged thereby are also preferably of tapering cross-sec-A tion. To lend rigidity to the joint, sleeve 14 is provided on its interior with a shoulder 15 adapted to register with the end of the shaft section 10 when the parts are assembled and the handle section 11 is formed with a shoulder section 10 as to be covered 'or concealed by that portion ofthe sleeve 14 that overlaps section 10. After assembly of the parts as described, the wooden handle section, the sleeve and a portion of section 10 are completely covered with the usual wrapping material 19 so that the finished article has the appearance'of an all steel shaft. With the wooden handle 11 forming a driving lit in the section 10 and the shoulder 16 on said handle section abutting against the interior shoulder on sleeve 14 as well as against the upper end vof shaft section 10, and with the cross pins irmly securing the several parts together, an extreme- V ly rigid connection is obtained. It has been found that such a connection will withstand all the strains placed upon it. In this way there is obtained a shaft where the material that has heretofore been scrapped is utilized, and, as pointed out, the resulting product will have the same feel to the player as an all wood shaft.;

To further reinforce the connection a reinforce rod 20 may be provided, said rod extending longitudinally through tlie handle section 10. yIt is preferred that this .rod'extend from a` point beyond the upper end of sleeve 14 to the extremity of the handle section within the metallic section 10v although it may terminate somewhat short of this point so far as its strengthening properties are concerned.

It isV also desirable to protect the wood handle section against changes in weather-conditions. For this reasonV a sealing compound may be applied to the wood handle before it is driven into the metallic section 10. There are numerous cements and sealing waxes which will accomplish this purpose. Preferably, the entirewood handle is weatherproof as farl as possible, the connection heretofore described between the wooden section' and metallic section might also be supplemented by the use of solder between the overlapping portions of sleeve 14 and section 10.

While the sleeve 14 has beenshown and described as provided with `a shoulder 15, it will be understood that this shoulder is not absolutely necessary and may be dispensed with, the sleeve having `a plane uninterrupted tapering inner surface adapted to make a wedging fit on the handle and shaft'proper.
