Description
Sept; 18, 1934. w. w. HACKE TT TUBULAR METALLIC SHAFT Fild June 26, 1930 Patented Sept. 18, 1934 1,974,271 TUBULAR METALLIC SHAFT Walter William Hackett, Oldbury, near Birming ham, England, assignor to The American Fork & Hoe Company, Geneva, Ohio,- a corporationof Ohio" Application June 26,1930, Serial No. 4 3,981 In Great Britain October 26, 1929 16 Claims. (c1. 273-$$) This invention has relation to tubular metal lio shafts adapted for golf clubs, and their manufacture.
Previously it has been proposed to construct such tubular metallic shafts having a handle part of substantially uniform diameter and a major part of uniform conicaltaper, but the flexibility is a constant one, and the varying requirements of players with regard to flexibility can only be attained by the manufacture of shafts having different diameters, the point of maximum flexibility being a constantvfor any particular size.
The present invention has for its object to produce tubular metallic shafts adapted for golf 5 clubs having greater adaptability in the flexing of the shaft according to the requirements of individual players. 1
With this end in view, I provide a tubular metallic shaft having its major or centre part of elongated conoidal formation, that is to say, having a. decreasing or arcuate taper as dilferentiated from a uniform or straight one. This major or centre part at its minor dimension preferably merges into a part of substantially uniform diameter having a dimension equal to the aforesaid minor dimension, and at its major dimension merges into the handle part also of substantially uniform diameter.
In order that this invention may derstood and readily carried, into practice,reference is had to the annexedexplanatory sheet of' drawing, upon which:- 7
Fig. 1 is an elevational View of a tubular metallic shaft suitable for a golf club, constructed .3 according to the present invention; Fig. 2 illustrates the shaft in a vertical sectional elevation, while Fig. 3 is a diagrammatic view of exagger-r ated form for clearly defining the conoidal portion. V I I In the embodimentof the present invention shown, the tubular metallic, shaft comprises a major or center part a of elongated conoidal formation, as differentiated from the previously proposed uniform conical taper. This conoidal formation at its minor dimension merges into a terminal part a of substantially uniform diameter, the mergance being preferably such that no part of the shaft adapted for disposition between the hand grip supporting portion a and the club head supporting end of the portion a is of a lesser diameter than the part a At its upper extremity the conoidal portion a merges into the handle part a also of substantially uniform diameter. The respective lengths of the parts a and a may 5 be varied, as may be desirable, although as ilbe fully unlustrated in the-drawing it is preferable that the part a should be disposed relatively distant from the club head supporting end of the part 0), to ensure that portions of the shaft relatively remote from the club head will be substantially flexed during use of the club in which the shaft is incorporated. .In fact, the part a may be dispensed with. Also, the portion almay itself have a tapered extremity for engaging the tapered socket in the club head. In a golf club of this invention the individual requirements of players can be readily accommodated by the relative proportioning of the parts a a and the part a if present.
The tubing may be formed by a rolling operation, or may beformed in any other suitable way as by the use of compression dies. As for instance, tubing of a diameter equal to the handle part a may be rolled or pressed down to constitutethe parts a and a vI claim:
1. A golf club shaft in the form of a metallic tube the medial portion of which, throughout a major portionof the length of the shaft, is of concave conoidal form.
2. A golf club shaft in the form of a metallic tube themajor portion of the length of which is of concave conoidal form, said shaft having a club end portion of cylindrical form constituting a continuation of .the smaller end of the concave 5 conoidal portion thereof and of the same diameter as the smaller end of said conoidal portion;
3. A golf club shaft in theform of a metallic tube'the major portion of thelength of which is of concave conoidal form, said shaft having a handleend portion of cylindrical formconstituting a continuation of the larger end of the concave conoidalportion thereof and of the same diameter as the larger end of saidconoidal portion.
4. A golf club shaft in the form of 'a metallic tube having a cylindrical handle portion of rela-- tively largediameter and a cylindrical end portion of relatively smaller diameter, the said shaft, throughout the medial portion of its length between the han'dleand clubend portions thereof being of concave conoidal form and of the same diameter at its ends as the handle and club end portions, respectively.
5. A golf club shaft in the form of a metallic tube the medial portion of which, throughout a substantial portion of the length of the shaft, is of a generally concave conoidal form.
