W. DUNN I Filed April 4, 1925 5 Clara, and State of California, have in-' Patented Jan. 5, 1926.

WILLIAM DUNN, 0F PALO ALTO, CALIFORNIA.

GOLF CLUB.

Application filed April 4, 1925. Serial No. 20,670.

To all whom it may concern:

Be it known that L'VVILLIAM DUNN, a subject of the King of Great Britain, and a resident of Palo Alto, county of Santa vented a certain new and useful Golf Club, of which the following is a specification.

The invention relates to golf clubs and particularly to the heads of golf clubs.

An object of the invention is to provide a hollow, metallic golf clubv head which will have the same feel in the hand and the same balance as a club provided with the usual wooden head.

Another object of the invention is to provide a hollow metallic golf club head in which the mass of the metal is concentrated behind the center of the striking face of the club, so that tendency toward hooking or slicing is eliminated.

Another object'of the invention is to provide a hollow metallic golf club head which may be filled with liquid to increase the weight of the head.

A further object of the invention is so to position the mass of the back wall of the head that the tendency of the club to twist, when the ball is notstruck exactly at the center of the driving face, is greatly reduced or eliminated.

The invention possesses other advantageous features, some of which with the foregoing, will be set forth at length in the following description, where I shall out-line that form of the invention which I have selected for illustration in the drawings accompanying and forming part of the present specification. In said drawings I have shown two forms of hollow golf club heads embodying my invention, but it is to be understood that I do not limit myself to such forms, since the invention as set forth in the claim may be embodied in a plurality of forms.

Referring to said drawings: Figure 1 is a perspective view of a gol club head embodying my invention, the shaft being broken away.

Figure 2 is a vertical transverse section of the golf club head taken in the vertical plane containing the line 2-2 Figure 1.

Figure 3 is a horizontal section of the golf club head taken in the horizontal plane containing'the line 33 Figure 1. v

Figure 4 is a section, taken on the same planeas Figure 3, through a modified form of, golf club head.

Figure 5 is a section taken on the vertical plane containing the line 55 Figure 1.

My invention relates to a hollow metallic golf club head 6, which is formed with a. closed cavity therein. The head is provided with an integral hollow neck 7 into which.

the shaft 8 extends, the sole or bottom 10 of the club head being provided with an .aperture in alinement with the axis of the neck into which the end of the shaft extends and in which it is suitably secured.

The head is provided with a front wall 9, the outer surface of which constitutes the striking surface of the club. The wall 9 is integral with the remainder of the head and is preferably somewhat thicker than the sole 10 or the top wall 11. The front wall is also preferably thicker than the walls at the heel and toe of the club. The back wall 12 of the club head is formed to concentrate a mass of metal directly behind the center of the striking face of the club head, so that as the club is swung against the ball, contact with the ball at either side of the center of the strikng face, will not cause the club to twist in such manner as to hook or slice the ball. This is accomplished by thickening the back wall 12 of the head by the addition of a thickened portion or bulge 13. which increases in thickness from its ends to the plane of the center of the striking face 9, this plane being indicated by the line 14. The back wall 12 and the bulge 13 are symmetrical with respect to the vertical plane of the line 14: and the mass of the back wall is concentrated adjacent the plane of the line 14, so that the center of gravity of the club will lie directly behind the center of the striking face 9. The front wall 16 of the pad 13 is preferably parallel to the striking face 9, so that the center of mass, considered vertically, of the club head is substantially directly behind the spot on the striking face by which the ball is hit when struck properly. This places the center of gravity of the club directly behind the ball in the line of movement of the club head, so that there is no tendency of the club head to twist, either to smother or loft the ball when it is somewhat improperly struck.

The front face of the pad 13 may lie in a straight line, as shown in Figure 3, or may be a curved line as shown in Figure 4:, in which the pad 15, which comprises the integral thickening of the rear' wall, has a curved front face 18 which produces a greater concentration of the mass adjacent the vertical plane passing through the center of the striking taco. By concentrating the weight directly behind the center of the striking face, the tendency of the club head to turn as a ball is improperly struck, is greatly reduced. lVhether the ball is struck on the heel or the toe of the striking face, the position of the mass of the head is so placed that the club head tends to follow through in its proper line of movement and is not twisted by improper impact against the ball.

When desired, the weight of the head may be increased by filling the cavity therein with Water and, for this purpose, I have provided an aperture, preferably in the toe of the club, which is closed by a plug 17, preferably of the screw threaded variety. \Vhen it is desired to increase the weight of the head, the plug 17 may be removed and liquid poured into the head and the plug replaced.

I have found that With a hollow golf club head constructed as disclosed herein, a good golf player will lengthen his drive approximately yards. This is due, in my opinion, to the resiliency of the club head, its perfect balance and the distribution of the metal in the head.

I claim:

A, golf club head comprising a hollow metal body cast as a complete integral structure and having a front striking face, and arear wall being thickened to constitute a substantial portion of the total weight of said head, the mass of said rear wall being symmetrically disposed with relation to a vertical plane normal to and bisecting said striking face, the remainder of the walls of said head being relatively lighter in construction compared to said rear wall.

In testin'iony whereof, I have hereunto set my hand.
