This invention relates in general to golf clubs but more specifically to the shaft employed in connection `therewith, and one of the objects Vof the invention is to provide an 6 improved cover or casing for the shaft which is adapted to be telescoped or sleeved over the shaft or core and the two bound together Vby a wedging operation, thereby rendering it possible to produce the casing as a separate l and complete article of manufacture which may be sold as such to be applied to a shaft or core. f

Such a casing may be applied without the services of an expert, and when placed upon l the core, will not only protect the core, but

will strengthen and re-inforce the entire portion of thecore or shaft which is disposed between the grip and head of the club without interfering with the required flexibility of the shaft and at the-same time the shaft will be of the desired weight and rigidity.

To the attainment of these ends and the accomplishment of other new and useful objects as wlll appear, the invention consists $5 1n the features of novelty in substantially the construction, combination and arrangement of the several parts, hereinafter more fully described andl claimed and shown in the accompan ing drawing illustrating. this l0 invention, an in which Figure 1 is aside elevation of a golf club constructed in accordance with the principles of this invention.

While this invention hasv been shown and will be particularly described in connection with a golf club shaft, it is to be understood that the term shaft as employed throughout the ication and claims is not to ybe con- -strue as a term of limitation and as being adapted for that purpose alone, but 1t 1s -to vbe construed broadly as being applicable' to any form of shaft, staL'or for any other similar purpose and particularly to shafts subjected to impacts thereupon'in directions transverse to the length thereof.

heretofore golf club shafts .have usually been made of wood and some shafts have been constructed of highly tempered metal, such as steel.

While satisfactory results have been obtained with these shafts there are many objections to them. y

Golf club shafts are subjected, among other things, to moisture and changing tem-` peratures, with the result that wooden shafts or cores not only absorb moisture but they 7 will warp and split, while metal shafts will corrode and rus j The corrosion and rust cannot be covered by'painting the shaft as the paint will not stick but w1ll chip or peel oif.

The corroding and rusting of the metal shafts results in considerable loss not only to the manufacturer but also to the merchant. as the rusting will occur upon the shaftsthat are carried in stock, there y precluding the sale of the same. 7

It is one .of the objects of the present invention to provide for the core or shaft a cover or casing of non-metallic hard material having tensile strength and which casing will not only reinforceth shaft or core but possesses considerable flexibiljty',{so as. not to impair the flexibility of the liaft, at the same time, the casing will permit the finished product to possess the desired weight and balance. v

After the present casing is once applied, the core or shaft will be protected and no further o ration, in so far as the-casing is concerne, is necessa ,K as a casing may be given the desired before being applied, andthe telescoping and wedging operation of the core and casing is all that is necessary to bind them together.

v The casing and core are both formed with l. a continuous and extended taper so that the Casin' will have contact with-the core through t e entire length ofthe casing.

' In carrying this invention into practise a tubular casing, of any suitable non-metallic material, may be employed which is adapted to be placed upon or sleeved over the core and to be fashioned to conform to the contour ofthe shaft o r core, the shaft or core and the casing being both continor both ends thereof according to the methods or means employed to fasten the head and grip of the club to the shaft.

In "either event, however, the casing will closely fit and have a continuous contact with the core or shaft throughout the en tire length of the casing.

A suitable material which has been found ,y

to be efficient for this purpose is pyroxyline, but it is to be understood that 1t 1s not desired to be limited to this particular product as an other material having the properties an characteristics herein vrecited may be employed.

A similar material 0r casing may be employed or placed over a shaft or core which 1s Constructed of low grade wood and which core is either solid or tubular, enabling the use of material which has heretofore been practically useless or at least unfit for use 1n shafts.

Referring more particularly to the drawing, the numeral lO designates a hollow tapered core `or shaft preferably produced from a sheet 0f metal brought into form, and 1l designates a tubular casing formed from a non-metallic hard and flexible material. The casing is tapered throughout its entire length and conforms to the contour of the core and the size of the casing in cross section is such that when the two vare telescoped they may be bound together by a wedging operation, and at the same time they will be independent of each other in that they will not be so fastened that they cannot be separated.

A head 12 is secured in any suitable manner to one end of the shaft thug formed and a grip or handle 13 is applied to or formed at the other end of the-shaft.

In Figure '4 the casing 11 is shown as terminating short of the end of the core or shaft 10, while in Figure 5 the casing is co-extensive with the length of the core.

The casing 1l being tubular and normally tapered may be readily applied and when in place upon the core will not only protect the latter, but will not interfere with the torsion or flex of the core. Furthermore the casing serves as a finish for the core, the surface of the casing itself being adapted to be finished either before or after it is applied to the core.

By this means it will be manifest that any desired finish may be given to the shaft as the casing may be made of any desired color or colors. I

The tapered metallic core may be either tubular or solid and when the casing is against rust and corrosion. c With wood cores or shafts the casing w1ll not only protect them against moisture and warping but will reinforce and brace them without impairing the flexibility or the tor,-I

sion of any core or shaft to which it is applied. i

In shafts, such as in wood shafts, its which the torsion and flexibility are usually too great, the torsion and flex may be reduced by use of this improved` casing, the amount of the reduction being controlled by the degree of thickness of the casing, and at the same time the proper weight and balance as well as the necessary flexibility will be maintained in the club.

By the ex ression normally tapered is meant that t e casing is formed into shape so that even though it is hard, it will possess considerable fiexibility and is complete in itself ready to be sleeved over and wedged upon the core.

While the preferred forms of the invention have been .herein shown and described, it is to be understood that various changes may be made in the details of construction Yand inthe combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of this invention.

What is claimed as new is 1. A fiexible golf club shaft embodying a tapered core, and a separate tapered tubular protecting and reinforcing casing of nonmetallic hard and flexible material of a length coextensive with the length of the entire portion of thecore which is disposed between the grip and head of the club, the said casing telescoped over the core and wedged thereupon, the casing and core havmg contact throughout the entire length of the casing and being independent of each other, the saidcore and the interior of the casing increasing in diameter toward the grip end of the club.

2. A fiexible golf club shaft embodying a v tapered hollow metallic core, and a separate tapered tubular protecting and reinforcing casing of non-metallic hard and flexible material of a length coextensive with the length of the entire portion of the core which is disposed between the grip and head of the club, the said casing telescoped over the core and .wedged thereupon, the vcasing and core having contact throughout the entire len th of which is disposed between the ip and head of the club, the said casing te escoped over the core and wedged thereupon, the casing and core having Contact throughout the entire length of the casing and being independent of each other, the said core and the interior of the casing increasin in diameter toward the grip end of the clu 4. A fiexible golf club shaft embodying a tapered hollow metallic core and a separate tapered tubular protecting and reinforcing casing of pyroxyline of a length coextensive with the length of the entire portion of the core which is disposed between the grip and head of the club, the said casing telescoped over the core and wedged thereupon, the casing and core having contact throughout the ent-ire length of the casing and being indeendent of each other, the said core and the interior of the casing increasing in diameter 20 toward the grip end of the club.

In testimony whereof I have signed my name to this specification on this 18th day of March, A. D. 1926.

HAROLD G. BARRETT.
