GOLF-CLUB.

Specification of Letters Patent.

Patented June 17, 1913.

Application filed June 13, 1910. Serial No. 566,478.

To all whom t may concern Be it known that We, JOHN L. KELLY and PATRICK L. MCARDLE, citizens of the United States, and residents of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Golf-Clubs; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to an improvement in golf clubs and consists of the matters hereinafter described and more particularly pointed out in the appended claims.

In the drawings Figure l is a frontelevation of our improved golf club in position addressing the ball, showing part of the shaftbroken away. Fig. 2 is a vertical section through the head of the club in a vertical plane through the axis of the shaft. Fig. 3 is a section through Fig. 2 on the line 3-3 thereof. l

A indicates the shaft or handle of the club and B the head. The head B is spheric in form with the center of the sphere located in line with the central axis of the shaft A. A segment of the sphere is cut away in front as at Z1 to form a bearing for a plate b1 which provides the driving face of the club. Said face b is preferably made at an angle to a vertical plane. A segment of the sphere is also preferably removed at the base of the head to provide a substantially flat rest b5 for the club when addressing the ball.

Our improved elub,formed as illustrated and described, is particularly advantageous for the reason that on account of its approxlmation to the shape of a sphere the center of gravity of tne head lies in or near the t plane containing the central axis of the shaft and the cent-ral point of the driving face, and but very little back of the prolongation of the central ax'l of the shaft. The club approximates perfect balance, and in its operation nearly approaches the ideal theoretical club,-that is to say, a ball at the end oi' a string. The removal of the lower segment of the sphere forming the head to provide the horizontal base b5 brings the center of gravity of the head more nearly into a horizontal plane through the center of the ball and prevents topping" the ball. Our improved club may be used equally well as a wooden club or as an iron or as a putter.

In order to vary the angle of the face of the club, the face plate 1 is attached to the head in such manner as to be removable as follows: The shaft A is provided with a reduced end part a having a screw-thread al formed at the upper end of said reduced part. The reduced end part of the shaft engages within a radial socket BL formed in the head. The upper end of said socket has an internal screw-thread B3 adapted to receive the thread al on the shaft. The face piece b1 is provided at its rear with a central stud b2 which engages within a radial socket b3 extending transversely through the head. A transverse-opening Z1* is formed in the stub b2 of the same diameter as and coaxial with the socket B2 to receive the reduced end a of the shaft. It is thus apparent that the face b1 is locked in place by the engagement of the reduced end of the shaft Within the transverse opening through the stud b2.

`A number of face plates b1 having their outer faces at different angles, as indicated by the. dotted lines b in Fig. 3, may be applied with each club so as to provide faces which may be used in place of the various wooden and iron clubs, such as driver, brassy, mashy, cleik or mid-iron. Our improved club may thus be used as a universal club, several different face pieces being carried by the player, either of which may be readily attached when a particular play requires its use.

IVe claim as our invention 1. A golf club comprising a shaft and a spherical head. the center of the sphere being substantially co-incidcntwith the central axis of the shaft and said sphere being cut away on one side in a plane, a removable face piece parallel to said plane, a stud formed on the rear of said face piece, the head being provided with 4a socket to receive said stud, and means for removably securing said shaft to the head and for interlocking the end of said shaft with said stud.

2. A golf club comprising a shaft provided with a thread near its end, a spherical head, a radial socket in said head adapted to receive the end of said shaft, part of said socket being internally screw-threaded, the center of the sphere being substantially coincident with the central axis of the shaft and said sphere being cnt away onone side in a plane, a removable face piece adapted to engage the plane side of said head, and a study formed on the 'rear of said face piece,

said head having a transverse socket to receive said stud, and said stud beingkinberlocked with said shaft end.- f

f3. A golf club comprising a shaft and a head, the center of the head being substantially in alinernent with the central axis of Y the shaft, and said head being cut away on one side 1n a plane, a removable face plece parallel to said plane, a stud lformed on the rear of said face piece, the head being provided with a socket to receive said stud, and means for removably securing said shaftto the head and for interlocking the end of said 15 l'shaft with said stud.

In testimony, that we claim the foregoing as our invention we afiix our signatures in the presence of two witnesses.
