Application med November 15, 1916. Serial Tic, 1311,3537.

' 1'0 an whom it may concern:

, of Cook and State of Illinois, have invented certain new and useful improvements in Golf-Clubs; and-I do hereby declare that the following is a full, clear, and exact de scription of the same, reference being had to the accompanying drawings, and. to the numerals of reference marked thereon, which form a part of this specification.

'This invention relates to an improved type of golf club, particularly a wooden club in which a new and efficient disposition of the balancing weight or weights. used in the head of the club imparts a spin to the ball which regulates the action of the ball in a predetermined manner upon alighting. This result is obtained by arranging the weight eccentrically with reference to what Ihave herein designated the normal axis is to be understood herein to refer to a line through the head in the direction of its impelling force, and passing through the center of impact, when the ball is properly struclrhy the head, and may be represented either by a line tangential to the curved line of movement of the head, and passing through the center of impact, or by a line projected perpendicularly to the radius of movement of the head and at the center of impact. Of course, in playing, the point at which the head contacts with the ball will vary according to the ability of the player, and the shot which he wishes to malts. Forexample, a poor player will occasionally top or slice p player may undercut somewhat to loft the 40 the hall or a ball, but there is a substantially definite point'contemplated in designing the cluh, and approximately at the center of the striking face, at which the head is designed to strike the ball when properly played, and the axis of impact passing through such oint is contemplated and considered herein as the normal axis of impact.

It is an object therefore of this in vcntion to construct a golf club wherein the balanc-- ing weight in the head 01" the club is positioned so as to impart a predetermined spin or rotary movement to the ball.

It is furthermore an important object of this invention to provide a golf club with a weight positioned cccentrically above the 110111131 axis of impact so as to give the ball, when hit, a forward spin to cause the ball to roll along distance after alighting.

It is also an object of this'invention to provide a golf club with a weight positioned cccentrically below the normal axisof impact so as to give the ball, when hit,a back ward spin, which causes the ball to rise quickly and minimizes theroll of the'ball when it alights.

In the drawings:

Figure l is a top plan view of a head of a club embodying the principles of my invention.

Fig.2 is a rear elevation thereof.

Fig. 8 is a detail section on line 3-3 of Fig. 2.

Fig. 4 Fig. 2.

Fig. 5 is a rear elevation of the head of another form of club.

Fig. 6 is a section on line 6-6 of Fig. 5.

is a detail section on line H of Fig. 7 is a view similar to Fig. 6, of a modified form of device.

as shown on the drawings:

The reference numeral 1, indicates as a whole the head of a club having a shaft extension 2, which shaft, as in golf clubs. of the ordinary construction, is thin andv somewhat flexible, and one surface of the head 1 of the club is beveled ofl with a slight inclination to afford a striking face 3. Recessed into the upper portion of the rear surface of the head 1, is a balancing weight i, of any metal or metal composition, arranged so that the heft of the head is above the normal axis of impact, and this weight is rounded oil" to conform to the contour or shape of the club head, and held socured therein by obliquely directed attaching screws 5. A sole plate 6, may or may not, as desired, be attached on the under surface of the head 1, of the club, and the usual fiber or composition insert 7, is provided extending for a short distance along the bottom oi the club at the lower edge of the striking edge thereof, as, shown in Fig. 4. This is, however, a usual and well known construction, and forms no part of the present invention, and hence is not illustrated in further detail.

in the form of device illustrated in Figs. 5 and 6. thvhead fet the club is denoted as plsitc extension clinched to the head of l the direction of which depends on the heft of the head of the club below the nornml of impact, is 21 oniaxis slicing Weight 10. field balancing iveighli 10, preferably of brass; or alloy, clihong h,

course, any suitable metal may he used, is integral with a sole plate exten sion. 17., extending over the entire lower surface of the head 8, cf the club, upwardly extending substantially vertically disposed attaching screws 12, provided for holding said balancing; eight and 5.216

club. Obliqnely arranged screws 13, also prordded, as shown in 6 so furifiher in holdi g the balancing id/and its sole plate c .e" n the head of the club.

In the form of dlviceilusfrnted if. A 2' I shown the head of the cub tioto, ccnote-d by reference provided with helmicin posed similar-l. lo the we prior ccnsiiritiotioin out separate fr plate 16. attached by attaching screws v desired nuiiiber of attaching screws 18, may be utilized to retain the sole plate ll} at tached upon the club.

In both Figs. (3 and 7 of the different constructions shown the usual lihcr insert the lewer end of the 5 face denoiedfhy the reference numeral 19, shown, corresponding to the fiber inseru shown Fig.

The operation is as follows:

The Weights herein provided arrzmged so to die purpose of the wee-hrs with which golfcluhs have her-ii 'hcreioforc prcviujd, nilfl'lkilji, to give the rich the desired balance and s vinp; t0 facilil lie its use, and in addition are adapted by icsson of their disposition cccentriccily or at one side of the normal axis of impact lo 51m: lo the ball, when hit a predetermined spi (he the normal axis of imp; 1"" zit which me vreight is loceled. which spinning moveriiciit "thus imparted to the hall is QiTGCiIlVl-E to ccncrol lhe action of the hell 'ii iicu esligliiing.

' zili fiils, causes i rill; would oliliierat the head or 'WlSB; and ivhere length ofdrive or distance is desired, this is a feature of considerable On the other hand, when the Weight is disposed s0 that the heft or greater weight of the club is below the normal axis of impact, illustrated in Figs. 5 to 7 elusive the head of the club, as it strikes the hell, hes a tendency to underriile lhe hall e hd thereby not only tends to cause the all. to rise quickly, but gives to the ball a backward spin, which when the ball. alights, prevents the ball from rolling, and enables the player to place the hall with greater accuracy.

The former construction. with the Weight top of the head, is preferably used in the club known as the driver, as this is the one with which long shots are usually made, and the latter construction, with the Weight at the base of the head, is adapted for use with the club known as the brassie, with. any clnh with which if is desired cm the hall to rise quickly and drop Howevch the disposiio secure either the forspin as desired, may he connection with any club withli-ion of Ward or e. Ej ployed 111 out departing from the spirit of my inveniron.

The Weight need not necessarily be located entirely at oneside of the normal axis of iii 1pm., but is arranged so that the prepc'ndcrancc of Weight, co the extent to secure the desired effect is at one side thereof, and in referring re the location of the Weight eccentricsl with reference to the normal s of impact, it is to he understood that re rel mee to the placing of the weight t a o n in sncn. manner that the preponderance OI the v-reight is at one side of the normal of impact. Also in the appended .is where I refer to the location of the weight cccenlarically at a vertical side of the ncrninl axis of impact I have reference to the placing of the weight either above or helcw such axis.

i i hile l" have shown and described my invention in a preferred form .21 T aware that various changes and niodiin-atic-i-s may he made therein withou t departing from the principles of my invention, and E therefore do not purpose lin'iiting the patent granted meenee rotary motion on. a substantially horizontal axis.

2. In a golf club the combination of a head having a flexible handle, said head comprising abody having a striking face at the front thereof, and Weight attached to the body at the rear thereof, so that the center of gravity of the heacl is at the rear thereof and disposed ecoentrically of the normal axis of impact and. substantially in a vertical plane through said, axis so as to flex the stem and actuate the head upon impact with it ball and thereby impart a rotary motion to the ball on a substantially horizontal axis.

3. In a golf club the combination of a head comprising a body having a striking face at the front thereof, a flexible shaft to which the head is secured, and a weight secured to the head above the normal axis of impact so as to impart to a. bell driven thereby, a predetermineoi overhead spin on a substantially horizontal axis.

In testimony whereof. 1 have hereunto subscribed my name in the presence oiqnvo subscribing Witnesses.
