The present improvements relate, in general, to golf clubs, and more particularly to clubs of the type known as woods although they may be adapted and applied in irons as well.
Among others, it is a primary object of the improvements, to improve the head of the club, so as to facilitate the swing or stroke. Means are accordingly provided to minimize resistance of the air and turf to the club head so that a sweeter, truer swing may be executed.
A further object is to provide a streamline club surface which will ride through the air with reduced resistance.
Another object is to provide means to facilitate turning of the club head during travel through the turf, so that the divot is reduced, and any sensation of impact to the wrists and arms of the player, is eliminated.
An additional object is to provide an improved sole or bottom surface of the wooden club head,
whereby the impact applied to the turf and vball will be similar to that applied by an iron club. A further object is to improve the wooden clubs, such as vthe driver, brassie, spoon, etc., so as to facilitate strokes on the fairway, from bad lies, from the rough and from sloping terrain.
Another object isV to provide an improved means for weighting wooden clubs.
The improvement of the wooden clubs without impairing their normal efficiency, their balance, and without imposing additional parts on the club head, constitutes further objects of the improvements.
Other objects and advantages of the improvements will be apparent to those skilled in the art; upon reference to the accompanying specification and drawings, in. which Fig. 1 is a front elevation of a golf club head embodying one form of the invention; Fig. 2 is a side elevation of the 01u10 head looking toward the toe of the club;
Fig. 3 is a bottom plan view of the club head; Fig. 4 is a section on line 4 4 of Figs. 2 and 3; Fig. 5 is a section on line 5 5 of Figs. 2 and 3; Fig. 6 is a section on line 6 6 of Figs. 2 and 3; Fig. '7 is a rear end elevation of the club head; Fig. 8 is a section on line 8 8 of Fig. 1. Fig. 9 is a bottom plan View of a modified form of club head;
Fig. 10 is a bottom plan view of a modified form of club head;
Fig. 11 is a perspective view on an iron golf club head illustrating the present improvements applied thereto;
Fig. 12 is a fragmentary view of the club head illustrating the improved weighting means.
Referring to the drawings, the wooden head I of the club has the usual forward driving or striking face 2, opposite rear face 3, toe portion 5 4, and heel portion 5 from which the integral shank or neck 6 extends. The club shaft 'l is fastened in any desired manner in said neck.
The character of club illustrated is of the brassie, spoon, driver or similar type, each lo of which has a conventional broad bottom surface, sole or base 8, which is normally in a substantially horizontal plane so that when the head rests on the ground, the upright forward face 2 will have the correct and intended inl5 clination from the vertical. This base 8, when resting on the ground, gives the proper lie to the club, so that in addressing the ball, the club head and shaft will lie in proper position, whereupon the player may close his fingers about 20 the shaft, thereby holding it in proper position throughout the swing. The preservation of this type of base is essential to prevent rocking of the head either transversely or longitudinally thereof, when the player is getting the lie of 25 the club, by having the shaft handle lay in his vopen hand.
The essentials of this bottom surface are therefore preserved, and none of their functions sacrificed in` the application of the present improve- 30 ments to the club head.
Upon reference to Fig. 3, it is seen that the bottom surface 8 of the head is made up of a transverse metallic plate 9, preferably of brass, and two divergng metallicwear plates I0 and 35 l l. These plates are countersunk in the head so that their surfaces will be flush with the wooden base surface of the head, as is usual in club construction.
'I'he metallic plate 9 extending across the for- 40 ward edge of the base, has a width about equal to that of the width of the base of an iron golf club head. This may be said to be approximately iive-eighths of an inch, but its dimensions may obviously be varied. It is well recognized that 45 an iron club offers less resistance to the ground than a wood club. Accordingly, the present improvements are designed to provide, among others, certain features of an iron in a wood, without sacrificing any advantages of the wood. 50
In accomplishing this end, and for other functional reasons hereinafter set forth, a depression or recess I2, countersunk from the normal base surface of the head, is provided. As illustrated, this depression may also be aptly termed, V-
a valley, furrow, void, channel or cavity, its nomenclature being unimportant. This depression I2, preferably originates in the rear face 3, and in the plate 9, about three-eighths of an inch from the forward face 2 of the club head. It is preferably elongated, and disposed in a manner so as to be concentric or aligned with the arc which the club head describes as it is swung by the shaft 'I by the player. Its aXis should preferably be normal to the shaft, which is the radius of the arc.
The forward end of the depression I2 is in, and flush with the surface of plate 9 and from that point it gradually increases in depth as it recedes toward the rear of the club head, whereupon it terminates in the rear face 3 in an arch-like cut out portion. (See Fig. 7.) Its depth at this end may vary from one-quarter to one-half of an inch or more, as desired. Likewise, the depression I2, is graduated in width, being flared from itsforward end to the rear end.
As illustrated, the contour of the depression is streamlined. Its forward tip is rounded out of the plate 9 While the remainder of it is rounded out. of the wood base. As seen in Figs. 4 to 7, the depression is deepest along the middle of the head, thence gradually rising toward the wear plates IU and II which are likewise rounded transversely. The plates are flush with the base of the depression, the curvature of the latter being Continued in the surfaces of the plates on both sides. A wedge or fan-shaped depression is thereby providing having gradual, streamline curves transversely thereof, having a gradual inclination longitudinally thereof, and having gradually diverging side limits defined by the plates I0 and I I. Beginning from a location just to the rear of the forward face 2, the depression starts from the normal base level and extends uninterruptedly through the rear face of the club head, being countersunk within the normal level of the base surface of the head. The present improvements have therefore added nothing to the sole or base of the head which would interfere with its normal lie, or impair its natural balance.
A club embodying the present improvements is more particularly adapted for use where the ball is lying on the ground or grass, as in a brassie or spoon, but it may be applied to drivers because of the reduction in air resistance afforded during the stroke. Furthermore, the provision of. the groove or depression I2 in the base of the driver would increase the use of that club on the fairway, where it is now used very seldom.
In use, the club is placed behind the ball on the fairway, and the normal lower surface of the head, defined by plates 9 to II and by cham- 'fered surfaces I5 and I6, gives the club the proper lie and there is no rocking or canting of the club from proper position. In the back swing, down swing and in the follow through, the streamline concavity or depression I 2 reduces the resistance of the air to the club head, thereby facilitating the entire stroke. 'Ihis promotes a smoother swing, and tends to make the club head ride on the air, especially where the stroke is executed with great speed and force.
As the end of the down swing is approached, the forward face 2 and brass plate 9 engage the turf and diginto same, removing a portion known as a divot, as the club head Iiattens out and starts to ascend from the divot hole. During this descent into the turf and ascent from same, the turf offers less resistance to the club head due to about its own axis. The rear end of the head which is higher than the front face during descent, swings downward as it enters the divot hole and thereafter is lower than the front face during ascent. The rear half of the base therefore actually goes down toward the ground, and by providing the void or cavity I2 at this location, this slight turning of the head is accomplished and facilitated without the ground or turf resisting or interfering with it. Accordingly the rear surface of the base and rear edge thereof, in prior structures, which met resistance from the ground during the aforementioned change of position, no longer is present to be encountered by the turf. The depression is wider as it approaches the rear of the head. This is preferable since the turf resistance to the head increases as the club head goes further into the turf and by increasing the width, the rear end of the head misses or goes over turf that might otherwise be encountered. The head having the streamline contour, therefore goes through the turf with greater ease, and assists the player in grooving his swing before and after impact With the ball.
This undulating bottom surface of the head in combination with the narrow plate 9, permits the club to simulate an iron, Only the plate `portion 9 of the base will take the divot, as in the case of an iron, and the remainder of the base, back of the plate, will offer little resistance. This feature is especially advantageous where the ball has a bad or cuppy lie on the fairway, or is in the rough.
As illustrated the wear plates I0 and II radiate or diverge from the cross plate 9. This contributes a stream-line effect with the arc of the swing, and protects the base of the head from stones, etc. The plates are rounded or curved transversely to complete the streamline eiect and to merge with the depression. It is obvious however, that the plates may be flat, if desired.
A modied form of the improvements is illustrated in Fig. 9. In that view the plate 9A is cut back along its rear edge., being somewhat crescent-shaped. The cavity or depression IZA is the same as that previously described except that no part of it is in the plate 9A. The shallow end of the depression in this form, originates at the rear edge of plate 9A. The wear plates may have they form previously described or they may extend from the diverging edges of the depression to the edges of the base and along the edge of plate 9A, as shown at IOA and IIA.
A further modified form is shown in Fig. 10, wherein the sole plate having the usual outline common in brassies and spoons, is provided with the depression or cavity IZB, which is the same in form, contour and function as that described above. In Fig. 11, an iron I9 is shown with a depression 20, countersunk in its base, illustrating one manner of applying the present improvements to irons, putters, etc.
The wear plates may be dispensed with, while the conventional horn ller 2I may be varied in shape and composition, or omitted entirely, if desired.
The usual cavity with lead 22 is provided, as illustrated. However, a modified and novel form of lead weighting is illustrated in Fig. l2. In that view, holes 25 and 26 are bored diagonally through the rear face of the club, so that they intersect within the club head, forming an X- shaped channel or passage. If desired, they may converge to form only a V-shaped passage. The lead may then be poured into the passage and when it solidies, its shape prevents it from coming out or being loosened. This eliminates the necessity of screw-boring the cavities for holding the lead.
This improvement 'simplifies the application of the lead to the head. Furthermore, it permits the rear end of the depression I2 to be graded to any desired depth, since the rear face may be cut back much deeper than in instances where the conventional form of lead 22 is used. In such cases the proximity of the depression I2, to the cavity, holding lead 22, and the very thin wood intervening, might cause the wood at that point to be split or impaired. With the present form of X or v-shaped lead insert 21, the wood of the rear face is solid between holes 25 and 26, so that the depression l2 may have any desired depth at the rear. The balance and swing of the club are greatly improved, because of the shape of the lead.
Various other advantages and modifications may occur to those skilled in the art, and may be made without departing from the scope and purview of the improvements.
