Definitions

  • This invention relates to improvements. in metallic tubes, shafts, or shapes and process of producing the same.
  • the metallic shaft or tube is claimed herein; the process is claimed in application Serial No. 293,419,
  • no object of the invention is the production of such tubes, shafts, or shapes having the desired torsion. Another object is so to form a metallic tube that said formation will duplicate a fine hickory golf shaft in torsion, weight, flexibility and balance. Another ob-.
  • the torsioning metallic construction of this invention is designed for use in golf club shafts and for other uses in tubular constructions where the shock-absorbing, stress-relieving characteristics of torsion are desired, or/and where the resilient spring action of torsion is desired.
  • Fig. 1 is. a perspective view of a tapered shaft shown with its larger end forward;
  • Fig. 2 illustrates the golf shaft of Fig. 1 in end elevation viewed from its larger end;
  • Fig. 3 is a perspective view of a some-v what modified construction of tapered shaft shown with its larger and forward;
  • Fig. 4 illustrates the golf shaft of Fig, 3 in and elevation viewed from its larger end
  • FIG. 5 is an endview from the smallerend METALLIC TUBE OR SHAFT Serial No. 293,419. Divided and this application fled Dctober 9, 1929. Serial No. 398,381.
  • Fig. 6 is a detail view of the smaller end of the metallic tube showing it covered with fabric and then wound about with cord;
  • Fig. 7 illustrates the tapered metallic tube as finished to constitute a commercial golf shaft
  • Fig. 8 is a larger scale detail longitudinal sectionalview through one-half of the lzeft-hgnd end of the finished shaft of Fig.
  • Fig. 9- is a perspective view of a non-tapered straight, shaft of this invention.
  • the preferred outside dimensions of a 43" driver shaft produced in the manner afoqesaid are approximately .625" at the large end and .338" at the small end.
  • the thin steel walls of t e shaft are spaced a uniform distance apart by the interposition of a spacer or separator, of suitable material, the thickness ofwhich determines said spacing and thereby also depreferably lea termines the de es of torsion in the finished tube or golf s aft.
  • the thinner. the lead spacer that is, the less the space between the t in steel walls, the greater the degree of torsion that will be developed under a given stress and a given diameter of shaft.
  • the lead filler was approximately 0.70" thick, and said shaft, tried in actual play, is *an unqualified success.
  • the shaft comprises two tubes, or shapes, or walls, of annular cross-section, one within the other, the inner joined to and suspended or supported from the outer; and that the seam m or m extendf now forced down into the slightly spread ing longitudinally of the shaft is constituted b opposin or contiguous edges which may a at as in igs. 1 and 2, or be separated as in I Figs. 3 and 4.
  • the opposing edges are not fastened together and hence may be said to constitute an open scam, the edges ofwhich are free for slight movement-relatively to each other when theshaft is subjected to torsional stress or strain.
  • Said open seam may be concealed, if desired, by inserting any suitable material between said opposing edges and then buffing said material flush with the metal, the filling material being anchored by means of the pressure of the walls of the seam thereon.
  • low carbon steel carburized toa high carbon content may be used instead of starting the process with a blank of high carbon steel. In that event it is preferable to weld the 'oint f. Instead of welding or brazing, the oint f may be formed by riveting. And, instead of starting with a blank of sheet metal or steel, proper lengths of cold drawn seamless tubin drawn or swa-ged to the desired taper and rawn, swaged or stro ped to the desired thickness of walls, may lie used and to the form shown in the drawing.
  • ralumin or similar alloy metal may be used, in the form of a seamless tapered tube, the wall thereof being thicker than that of steel but gauged to weigh the same.
  • the thickerwall of course has less torsion, but this may be offset by correspondingly decreasin the space between the two walls and the desired torsion thus obtained.
  • Molybdenum steel tubing may be used.
  • the metal shaft it is desirable to make certain additional provisions for its use as a golf club shaft.
  • Acetone or similar elastic cement having the characteristics of bonding and shrinking the material to the shaft
  • Fig. 6 is then slipped over said section.
  • Said sleeve p is larger (about 4 larger in diameter) than the shaft, thus providing an excess of fabric for a purpose stated below.
  • ⁇ Vedges (not shown) are now forced into the open fseam of the shaft just beyond each end of the fibrous-sleeve p, thus slightly spreading said seam.
  • the excess of fabric in the sleeve p is seam, as shown at g in Fig. 5, thereby drawing the fabric to a tight fit around the shaft.
  • the two wedges are now withdrawn allowing the spread seam to spring back to a tightly closed condition in which it securely grips and anchors the fabric between its edges.
  • the outer and projecting end or head of the plug is of larger diameter such as to be approximately flush with the outer. surface of the outer wall of the shaft.
  • a shoulder w (see Fig. 8) at approximate right angles to the axis of the plug.
  • a wedge-shaped collar y Around the plug inside said shoulder there is a wedge-shaped collar y.
  • the collar 11 on the plug is notched at y (see one half of the notch shown in dotted line in Fig. 8) to receive the walls at the seam of the metal shaft.
  • the headed pin or rivet :v of Figs; 7 and 8 may be omitted and the edges of the notch y utilized to lock the walls of the seam together, the stem of he plug/making a driving fit within the metal shaft;
  • 'Ihenietal shaft of this invention instead of being tapered. as has been described with relation to Figs. 1 m 8, may be non-tapered, that is to say, it may be in the form of a straight shaft. of approximately uniform diameter or cross-section, such as the shaft G shown in Fig. 9, which may be produced from a blank of sheet steel of uniform width throughout by the recess described in said application of whic this is a division.
  • said open seam may be similar to that shown atom in Figs. 3 and 4, formed by rounded op osing edges such as showniat a and k in saidfigures.
  • the ends of the non-tapering shaft may be prepared to receive a grip and a head, respectively, in any suitable way, for example, in the manner hereinbefore described and illustrated in Figs. 5 to 8 inclusive in reference to a tapered shaft.
  • the outer wall of both the tapered shaft of Figs. 1 to 8 inclusive and the non-tapered shaftof Fig. 9 may be reinforced where it leaves the neck of the head by inserting strips of hickory or spring metal, convex in ,crosssection, between the two walls of the shaft,
  • metal tube or shaft claimed herein'as a new article of manufacture is not limited to one produced by the particular process illustrated, described and claimed in the application of which this is a division.
  • open seam is used as designating the seam extending longitudinally of the shaft formed by the abutting or closely contiguous edges of the folded blank, which edges are free for movement relatively to each other, and examples of which seam are shown at m in Figs. 1 and 7, where the opposing or contiguous edges neatly abut together, and at m in Figs.
  • hickory has sundry imperfections and disadvantages. It is well known that hickory shafts are prone to warning, which renders them undesirable for their intended use. Moreover, hard, straight hickory shafts are now very scarce, andaccording to Government statistics the supply of high grade hickory timber, suitable for the mantis facture of golf shafts, is nearing its end.
  • hickory shafts are highly sensitive to changes of temperature and humidity; the effect of rainy Weather and hot weather being to increase their flexibility and degree of torsion, and vice versa,
  • a hickory golf shaft lacks constancy (or dependable uniformity of condition and action); and because of its variability and its susceptibility to even the ordinary changes of weather and other conditions, it is often the major contributing cause of un'steadiness or irregularity in the play of the user.
  • Many off days, that are commonly attributed to the golfers themselves, are in feet off days for their hickory shafted clubs.
  • the torsion of hickory. as imparted to a steel shaft by the herein described invention gives these outstanding advantages over steel shafts heretofore on the market: (1) It absorbs the jar of impact, thus cushioning the feel of the shot; (2) it counteracts the turning of the wrists at the moment of impact, thus producing” better direction; (3) it snaps the ball away on the rebound and thus contributes to a longer shot.
  • a metal tube or shaft susceptible of torsioning and having a seam extending longitudinally thereof formed by opposing edges which are free for slight movement relative to each other in said torsioning.
  • said tube or shaft I being constituted by two tubular walls of thin metal substantially uniformly spaced apart one within the other, and said walls being continuous with each other at both edges of said longitudinal seam.
  • a metal tube or shaft capable of torsioning and having a seam extending longitudinally thereof formed by contiguous edges which are free for slight movement relative to each other in said torsioning, said tube or shaft being constituted by two tubular walls of thin metal of substantially the same shape in cross section and substantially uniformly spaced apart one within the other, and said walls being integrally continuous with each other at both edges of said longitudinal seam.
