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

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 .
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

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
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
head [8, but it will, of course, be understood that
either of the forms shown may be applied to solid

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

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
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.
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.
