SHAFT FOR com-cross.
Specification of Letters Patent.
Patented Jan. 12, 1915.
Application filed January 28, 1914. Serial No. 813,926.
To all whom it may concern:
Be it known that I, ALLAN E. LARD, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Shafts for Golf-Clubs, of which the following is a specification.
My present invention pertains to an improved shaft for golf-clubs, and the main object of the invention is to produce a metallic shaft embodying all the desirable and requisite features of the wooden shaft, and eliminating the objectionable features inherent thereto, namely, breaking, warping, becoming dead or set, and the care and attention necessary during and after exposure to rain. 1
A golf-club shaft must, as is well understood by those skilled in the use of golf clubs, have proper weight, and also proper balance, and the shaft must have the right whip to be effective, the whip being a matter of degree, varying with the taste and requirements of difi'erent players.
Satisfactory metallic golf-shafts have not, so far as I have been able to ascertain,
as yet appeared, and the main difficulty has been the inability to secure the absolutely essential feature of torsion. An ordinary hollow steel golf-shaft has no torsioning qualities under impact, and such torsioning or twisting of the shaft is just as indispensable in a metallic shaft as it is in a wooden one.
The face of the head of a golf-club is offset or out of line with the shaft, and when the impact against the ball occurs the wooden shaft not only flexes backwardly, but also twists or torsions, and it is such torsioning that adds a propelling power which assists in lengthening the drive. Furthermore, this torsioning, coiiperating with the turning of the wrists (it being a wellknown fact that the wrists must turn in every properly executed golf swing where distance is required), tends to give a long straight ball with a minimum efiort. In short, a longer and straighter ball can be obtained with a live shaft that torsions than .with one which does not.
Another important feature of the torsion-.
ing is that it tends cushion the blow,the result being a yielding, pleasant sensation rather than a sudden or jarring one. When the head of-the club, traveling at a high rate of speed, impacts against the ball, the tendency is to turn the shaft in the hands, and it will be readily seen that the shaft less liable to jar when this sudden, twisting effect is cushioned by the torsioning action of the shaft, such action traveling the length of the shaft and being, to a certain extent,
more gradually and pliantly conveyed to the gripping hands. It is, therefore, quite apparent, and a well-known fact to those versed in the science of the game, that torsion is indispensable in a wooden golf-shaft, and it naturally follows that it is just as indispensable in a steel golf-shaft.
Several embodiments of the invention are shown in the annexed drawings, wherein:

showing the ears on the ribs bearing (ii-- rectly upon the central tube instead of being overlapped; Fig. 18 is a side elevation shown in Fig. 18; and Fig. 20 a detail perspective view of a, still further modification.
Referring to the construction shown in.
Figs. 1 to 9 inclusive, and which I may here state has beenactually produced and tested out, 1 denotes a central tube formed of spring steel, the same being relatively small and light. It is surrounded by a plurality of inverted U-shaped ribs, said members being indicated by 2. These ribs' are formed from the blank shown in Fig. 3, and as will be noted upon reference to Figs. 2 and 5, they are of greater depth at the upper or grip end of the shaft than at the lower end;
in other words, they taper in depth from the upper to the lower end of the shaft. Each rib is formed with a plurality of laterally-extending ears or lugs 3, which in the completed rib are slightly curved and overlap the lugs or ears upon the adjacent rib when the parts areassembled about the central tube and secured. thereto, producing what may be termed an outer slotted tube. These lugs or ears may be welded to the central tube and the ribs have no immovable or solid connection therewith except through such ears, and thus as the outer slotted tube or ribs torsion the central tube torsions also under impact and is prevented from collapsing (which would otherwise occur owing to its lightness and size) by the exteriorly placedand longitudinally extending strengthening ribs." The object of the relatively light central tube is to provide a brace or support for the outer slotted tube or ribs, but its presence will not prevent the shaft from torsioning. The cars or lugs of the various ribs, as will be-readily appreciated, may lie side by side along the shaft, as in Fig.17, or they may abut, or be otherwise arranged. It has been found that a shaft thus produced will'have the necessary balance, will fall within the requirements of weight of the ordinary golf-shaft, to wit, from six to six and three-fourths ounces,
and will likewise have the necessary whip and will torsion under impact. diameter of the tube of the shaft which I have actually tested is seven-thirty seconds and the thickness of wall .014 of an out doing away with its susceptibility of .being torsioned, to prevent collapse of-the,
The outside tube. Of course, the ribs or outer tube tend to reduce the torsion to a certain degree, and the torsion is affected by the diameter and thickening of both tubes. The number and a construcignated by 4,which are rounded ofi' upon their outer surfaces so as to be upon a somewhat larger radius than the outer face of the ribs 2, and the wire or other securing device 5 is wound around the same. Over this is placed. a strip of listin 6, and any preferred form of grip sur ace 7. The nesting of the strips 4 between the ribs and the winding of the members 5 and 6 thereabout securely hold the grip in place. The wood being recessed to receive the ears which it .overlies, prevents any endwise movement of the grip with reference to the shaft. It will, of course, be understood that any suitable cementitious material may be used in addition, but this in practice has not been found necessary. The lower small end of the shaft is secured in the head of the club in the following manner: The wooden strips 8, being recessed to receive the ears, are laid in the grooves between the ribs sheet of metal bent to shape and having overlapping ears, aslO and 11, which are welded to the tube. Said ears, instead of overlapping, may be placed in any other suitable relation to each other, as above indicated in connection with Fig. 17 A shaft made in accordance with either of these constructionsmay be readily assembled and all the ribs secured in place without dificulty, through the employment of electric spot welding, or any other approved method.
In Figs. 12 to 16 inclusive I have shown a further modification of the invention,
other suitwherein the .shaft is produced from sheet metal without the use of a central supporting tube. It may be said to comprise a plurality of ribs formed from a single sheet of metal in such manner as to reduce a tapered shaft. Assam be a? apprecbnstruction may be producedin several ways, as by rolling between forming dies,
cutting out the-openings between the connecting ears or members (which secure the ribs together) at the time of their formation or thereafter, or producing a blank from which the ribs may be pressed out, as is illustrated in the fi res last referred to.
In Fig. 13 a blan is'shown consisting of a series of longitudinally-extending members connected by cross bars or ears 12. A blank thus produced will be sub'ected to the action of suitable dies, whereby longitudinal U-shaped members 13 will be formed, connected as just noted, by the ears or members 12, with outwardly-extending ears 12 along each side of the blank. These U-shaped members, as will be best seen upon reference to Figs. 11 and 15 are of greater depth at the handle or grip end than at the lower end of the shaft. To produce the shaft, the ribbed blank is brought to the form best shown in Figs; 11 and 12, and the marginal ears are overlapped and welded. With this construction the shaft may he made of a metal slightly heavier than in the constructions be ore referred to, inasmuch as no central tube is present, and the weight of said tube may be carried into the metal of the shaft. with any suitable wrapping, as for instance, wire as 12", Fig. 11. A shaft constructed in this manner will torsion, and has the whi and spring necessary to a successful golf club shaft.
The whip under any of the constructions hereinbefore set forth, may be located or accentuated at any desired point in the length of the shaft by variation in the height or size of the ribs. Thus, the whipmay be localized down near the head, up near the grip, or in the middle of the shaft.
It is, to be understood that in all the constructions herein set forth a greater or less number of ribs may be employed. In practice I have used four, that number keeping the shaft within the required weight,'andgiving all the desirable features before alluded to. 7
Thev shaft may be treated or enameled .to prevent rust, and where it is made of highgrade steel and properly tempered, its life is almost limitless.
Under all of the constructions hereinbefore referred to there is resent what may be termed a slotted sh it. Thus, in the constructions shown in Figs. 1 to. 9 inclusive, and in the constructions illustrated'in Figs. 10 and 17 slots are formed betweenthe ears and between the edges of. the ribs and'the dj en Jae ne s nt a th I v form 'shown in Figs. 11 to 1'6-"inc1usive there The shaft may bereinforced less the shaft will torsion, and vice versa.
It is'readily conceivable that with a blank formed as shown in Fig. 1'6, the ribs may be turned in a direction the reverse of those disclosed in Fig. 11, in which instance the vribs would be internal of the shaft with the vedges thereof extending outwardly. This,
however, is not as desirable a construction as that disclosed in Fig. 11. a
In Fi s. 18 and 19 there is shown a further mo ification, in which the tubular member 14 and the ribs 15 are Qdrawn from an ingot or .formed from one piece. In this construction the openings 16, designed for the v purpose of permitting torsion, are punched or milled.
The tapering of the shaft is produced by grinding away the outer surface of the ribs, and the whip is placed in the' desired section by reducing the height of the ribs in that 10- cality where it is desired the whip should appear. I
I have produced a' shaft ofthe charactei described by milling the flanges or ribs from a steel tube having a three-sixteenths inch inside diameter and an outside diameter 'of one-half inch. These flanges may, however,
be drawn instead of milled.
The depth of the ribs or flanges adjacent the grip end of the shaft is slightly over oneeighth of an inch. As will be readily seen upon reference to Fig. 18, the ribs may have a stepped,'tapered form. adjacent the lower end of the shaft, as indicated at 17, in order to facilitate the securing of the shaft in the head of the club. At the grip end the ribs, as shown maybe left of a height sufiicient to enable one to readily secure the proper gripping surface thereon.- Strips of wood may be embedded between the ribs, as before described. With this construction the clubmaker may, by merely grinding away the ribs, produce the whip at any desired point, in much the same manner as it is now obtained by reducing the diameter of a Wooden shaft which is commonly effected by scrapinkg the shaft with a piece of glass or the li e.
While I have described the invention somewhat at length, and the different ways in whichit-may be carried out, I do not confine myself to tapering by grinding, milling stamping or any specified methods; If it .is' found desirablejto produce the taperby 'drawingmayldo so.
In the ,eniployfiientof the terms slots the shaft. Thus, for instance, in Fig. it
may be said that the shaft is provided with longitudinally-extending slots located be-' tween the longitudinally-extending ribs, and the same is true of the construction disclosed in Figs. 18 and 19, wherein, in addition to thelongitudinally-extending slots formed in the production of the ribs 15, openings 16,
- in the central tubular body portion arelikewise provided to permit the desired amount or degree of torsion. In other words, I may or may not have openings in the central body portion of the shaft, dependent, of course, upon the size and thickness of the central body, as hereinbefore set forth.
