C. B. SIPPEL SHAFT FORA GOLF CLUBS AND THE LIKE Oct.. 23

Filed March 8, 1928 Fatented ct. 23, 1928.

UNITED STATES CHARLES B. SIPPEL,

F CHICAGO, ILLINOIS, `ASSIGNOR TO PYRATONE PRODUCTS COR- POBLATION, OF CHICAGO, ILLINOIS, A. .CORPORATION OF ILLINOIS.`

SHAFT ron. GOLF oLU'Bs AND 'rim Linn.

Application led March 8, 1928. Serial No. 260,005.

In United States Letters Patent 1,600,389 and 1,600,390, issued September 21, 1926,

there is described and claimed an 'improvedA ter it is shrunk thereupon, thereby rendering i@ it possible in the manufacture thereof to employ low grade material in the formation of the core, the casing being also adapted for use as a covering for hollow metallic cores, the casing or covering not only strengtheningand i reinforcing the core, but the required flexibility of the shaft will not be interfered with, while at the same time t-he shaft will be of the desired or required weight and rigidity. In the manufacture of golf c lub shafts it is sometimes desired to ornament the same by providing dierent colors, but with a continuous casing which extends for the length of the shaft between the head and grip of the club it is dicult to produce different clearly designed zones of diiferent colors.

It is one of the obj ects of the present invention to provide an improved casing or cover- 'ing of this character which will be of sectional construction whereby a plurality of sect-ions of different colors may be assembled upon a shaft and secured together, the sections being assembled upon the core or before they are placed thereon.

The completed casing or covering is secured to the core in any suitable manner preferably either by shrinking or wedging the same upon' the core, sections of dierent colors being suitably arranged and Secured together in any suitable manner, and if desired in a manner so as to resemble a bamboo shaft having joints or protubera'nces .at predetermined intervals throughout the length of the shaft.

To the attainment of these ends and the accomplishment of other new and useful objects asy will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the .accompanying drawing illustrating this invention, and in which Figure l is an elevation of a golf club shaft constructed in accordance with the principles of this inventiono Figure 2 is an enlarged detail vertical sectional view of a portion of the shaft 'taken through the casing with the core in elevation andshowing one method of connecting the pronimate ends of adjacent casing sections.

Figure 3 is a view similar to Figure 2, showing another means of fastening the proximate ends of adjacent sections.

Figure 4 is a view similar to Figure 3, showing another manner of fastening the proximate ends of adjacent casing sections.

Figure 5 is a view similar to Figure 2, showing still another means of securing the proximate ends of adjacent casing sections.

Figure 6 is a detail sectional view taken on line 6-6, Figure 5.

`Referring more particularly to the drawing the numeral 10 designates a core formed of any suitable material, here shown as being of a tubular construction and tapered, but it is to be understood that the core may be constructed of any suitable material, may be solid and. may be' of uniform diameter throughout its length.

Secured about the core 10 is a casing constructedvof any suitable non-metallic hard and flexible material, preferably! pyroxylin. These sections may be of any desired length and when the core itself is tapered the 'respective sections of the casing are tapered and the sections progressively taper so that' when they. are arranged end t0 end the'diameter of the inside of the casing thus formed will be only slightly larger than the external diameter of the core. When the casing thus formed is applied to the outside of the core to strengthen, reinforce and protect the same, it may be secured to the core .by either a wedging action or the casing may be shrunk about the core.

In the form of the invention shown in Fig-V ures 1 and 2, one end 12 of each of the casing sections 11 is driven into the proximate adjacent end 13 of the next adjacent section so as to secure the sections together and the por-a tion 13 of the respective casing sections will form protuberances or formations designed by the reference numeral 11i in Figurel 1, to

. simulate the joints or protuberances of bamboo, causing the-shaft, when nished, to resemble a bamboo shaft.

In the form of the invention shown in Figure 3, one end 15 of each of the casing les 1 sections is shaped so` as to -receive the proximate end 16 of the next adjacent section 1n such a manner that the outer peripheries of each of the sections will coincideto present ing 18 may be provided around the outer faces of the casing-sections.

In Figure 5 the proximate ends of the adjacent casing sections 11 are secured together by threading one of the sections into the other,.as at 19.

In all of the forms of the invention the casing thus formed'of sections will tight-lyl fit upon thecore.

With this improvement it will be manifest that the casing sections may be manufacture in any desired colors and any combination of colors may be produced by correspondingly assembling the sections endto end, with the result that a very ornamental shaft will be produced.

The sections may be secured together and assembled directly upon the core of the shaft or they may beall assembled or connected together before the core 'is telescoped-thereinto.

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 and in the combination and `arrangement of the several parts, Within the scope of the claims, without departing from the spirit of this invention.

What i's claimed as new is 1. A flexible golf club shaft embodying a core, and a separate tubular protecting and reinforcing casing of non-metallic hard and flexible material telesco ed over the core, said casing being formed o a plurality of separate tubular sectionsI arranged end to end,
