Application September 14, 1936, Serial No. 100,615 1 Claim. In the use of golf clubs, if the player be right handed, it is customary to guide and control the swing and delivery of the shot with the left hand, and to employ the right hand primarily for the 5 purpose of adding speed and force to the blow. A true coordination of movements requires that the guiding function of the left hand be unim~ peded and not interfered with by the grip of the right hand, and in these circumstances, an 10 expert player will ordinarily grip the club more ?rmly at its upper end with the left hand and with a lighter grip in the right hand so that the turning or twisting movements of the shaft necessary for its accurate control will not be 15 interfered with. It is frequently difficult to coordinate these gripping movements satisfactorily since the ordi nary handle grip of a regulation shaft is covered throughout with a winding of leather so that 20 a uniform coef?cient of friction is presented to both of the hands. The object of the present invention is to provide a hand grip having its upper covering section formed of rubber or a (Cl. 273—81) Fig. 5 is an enlarged sectional view taken on the line 5 of Fig. 4. Referring to Figs. 1, 2 and 3, 10 represents a tubular, tapered steel golf club shaft of a type now commonly in use having a head ll of any . desired'character. The upper end of the shaft thereon an upper grip section [3 in the form of a sheath of rubber or other similar rubber-like material or composition having a relatively high coefficient of friction. The upper grip section is preferably of a length to accommodate the palm 15 of the left hand throughout without protruding downwardly to a great degree, although some players may prefer that the upper section be extended somewhat to permit the hands to be lowered to the desired degree in playing short. .0 The length of the upper rubber frictional sec tion will be determined more or less by the play er’s preference, and some players may not desire to employ an upper grip section which is con rubber-like composition possessing a relatively 25 high coefficient of friction with the lower section of the handle grip formed as heretofore of leather long as sufficient provision is made to afford a or an equivalent composition having a relatively low coefficient of friction. In these circumstances upper hand to secure the bene?ts characteristic the player will naturally and instinctively secure of the present invention. 30 a tighter or ?rmer grip by the left hand than by the right hand irrespective of attention di rected to this requirement, and experience has shown that the average performance of a player, whether an expert or one of only moderate skill, 35 can be materially improved by the use of a han dle grip having the characteristics of the present invention. Experience has also shown that the provision of a frictional grip for the upper hand tends to 40 prevent a twisting or turning of the shaft at the instant of impact so that there is a reduced tendency to divert the course of the ball from the line of approach of the club during the swing. Further objects and details will appear from the 45 description of the invention in conjunction with the accompanying drawing wherein: Figure 1 is a side elevation of a golf club hav ing a steel shaft and having a handle grip where in the upper and lower sections abut in flush 50 relation to one another; Figs. 2 and 3 are enlarged cross-sectional views taken on the lines 2 and 3, respectively; Fig. 4 is a side elevation of a wooden golf club shaft embodying the features of the present in 55, vention in a modi?ed form; and ' constitutes the handle section and is provided with the usual inner fabric covering 12. The upper end of the shaft which is grasped by the left hand of a right handed player has mounted 1o) tacted by the entire palm of the left hand so I‘ su?iciently extended gripping surface for the Below the upper section I3 is a lower grip to section 14 which in the form shown in Fig. 1 terminates in its upper end in ?ush relation to the outer surface of the upper section so that there will be no break or shoulder at the point of junction for the two sections. The lower sec- 35 tion I4 is preferably of leather wound spirally in conformity with the prevailing practice, and since the lower grip section differs in no matter, save in length, from conventional practice, a further description is not deemed necessary. 40 However, the present invention may have its embodiment of a lower grip section formed of material other than leather provided that it pre sents a gripping surface having a lower coeffi cient of friction than that of the upper section. 45 Fig. 4 shows a modi?cation in which a leather wrapper l 5 extends throughout the handle of the shaft in conjunction with a tubular rubber sheath H5 which overlies the leather wrapping and af fords the gripping surface for the upper hand. 50 In this instance the upper section I6 is of a larger exterior diameter than the lower gripping section which affords a shoulder or abutment at the lower end of the upper gripping section. Fig. 4. illustrates a wooden shaft I‘! having a club 55 2 2,188,695 head [8, but it will, of course, be understood that either of the forms shown may be applied to solid Wooden shafts or to metallic shafts interchange ably, and that the particular types of shafts de scribed serve merely to illustrate particular em bodiments of the present invention. the ball at the center of the driving face will tend to impart a twist to the club, which, however, will be overcome by the friction afforded by the upper grip. The construction of Fig, 4 is one which permits the effective diameter of the upper end of the In use the upper or left hand in the case of a club to be increased to any desired degree either right handed player will grasp the upper gripping section either throughout its length or through so much thereof as is necessary to obtain the by the choice of a rubber sheath of the required thickness or by the use of padding or the like ?rmness of grip required in controlling the swing of the club and the delivery of the shot. Some players may prefer the construction illustrated in Fig. 4 which presents a larger or thicker handle section at the upper end which may in some cases afford a more effective grip than the section illus trated in Fig, 1. Irrespective of the detailed construction demanded by the personal prefer ence of a player, the upper section of the handle will afford a more effective grip for the upper hand than can be obtained in the case of a club having a handle of uniform frictional coefficient throughout. Furthermore by providing a fric tional grip at the upper end, it becomes unneces sary for the player to direct particular attention to the tightness of the grip imparted by the left hand, since twisting or maladjustment will be prevented by the inequality in the frictional sur faces presented even though the shaft be grasped with equal ?rmness by both hands. The value of this feature is particularly evident at the instant of impact since any stroke which does not impact interposed beneath the sheath prior to its being 10 ?tted on to the upper end of the handle section of the shaft. It will be understood that such terms as rubber and leather are employed merely as representa tive of a class of materials and that the essence 15 of the present invention lies in the provision of a handle grip having upper and lower sections pre senting varying coe?lcients of friction irrespective of the particular substance or material employed to obtain this result. 20 I claim: In combination with a golf club shaft having a handle of leathery material, an upper cylindrical hand grip encircling and frictionally engaging the upper end portion only of the handle mate 25 rial, and comprising a tubular section of rela tively thin and ?exible rubber material, the tube being of a length substantially equal to the width of an average hand and of a diameter materially less than that of the shaft handle on which it is 30 engaged to elastically adhere thereto.
