DOUBLE-FACED GOLF CLUB Filed Aug. 4, 1952 INVENTOR. CLARENCE W. JAG KSON ATTORNEYS Patented Dec. 8, 1953 Clarence Jackson, San Mateo, Calif.

Application August 4, 1952, Serial No 302,500

3 Claims.

The present invention comprises an improvement in golf clubs, the invention being directed towardthe provision of means whereby a single club may serve for a plurality of uses. One object of the present invention is to provide a golf club which may be readily adapted for use by right-handed or left-handed players. A further object of the present invention is to provide a golf club having a pair of oppositely disposed impact faces of differing character and a shaft which may be disposed in oppositely directed, angular relationship to the head whereby the sameclub may be used for dual purposes, such as would be the case if one of the impact faces were designed for driving a hall from a tee and the other were designed for lifting the ball from the fairway,"

such as in the manner of a brassie or spoon. The ultimate object of the present invention, therefore, is to provide a four-way golf club having opposed impact faces of differing character and which may be used by either a right-handed or left-handed player.

A further object of the present invention is to provide a golf club of the foregoing character which is easily formed of durable materials and which may be economically. fabricated and assembled.

A further object of the present invention is to provide a golf club of the foregoing character comprising a metal core which is symmetrically disposed with respect to the shaft whereby the weight of the club will be properly distributed in any position of use, and a pair of plastic impact members disposed upon the opposite faces of the metal core. By reason of this construction, impact faces of differing character may be provided, any difierence in volume on opposite sides of the head involving plastic material of light weight, the effect upon the balance of the club resulting therefrom being negligible.

The foregoing and other objects and advantages of the present invention will be more readily apparent from inspection of the following specification, taken in connection with the accompanying drawing, wherein like numerals refer to like parts throughout.

Inthe drawing,

Fig. 1 is a face view of a golf club built in accordance with my invention, only a portion of the shaft being'shown;

Fig. 2 is an end view of Fig. 1;

Fig. 3 is a plan view of Fig. 1;

Fig. 4 is a vertical section taken substantially along line li of Fig. 3;

Fig. 5 is a vertical section taken substantially along line 5-5 of Fig. 3;

l Fig. 6 is a verticalsection taken substantially along line 5+8 of Fig. 4; and v Fig. 7 is avertical section, on an enlarged scale, taken substantially along line 1-1 of Fig. 5. .;..'Ihe present invention comprises a golf club consisting of a head, generally indicated by the numeral It, and a shaft, generally indicated by the numeral H. The shaft may be of any suitable construction, in the present instance colprising a tubular steel shaft 13 mounted in ahosel in the stem of a lower end portion I l. The lower end portion I 4 consists of a symmetrical, metal member having parallel side surfaces l5 and a pair of toes IE symmetrically extending in opposite directions, and is provided with a centrally disposed, transverse bore [1 for reception of a transverse pivot l8. The centerline of the borel'i is disposed along the intersection of the major axis of the lower end portion in the vertical sense and the major axis of the lower end portion in the horizontal sense, the former axis including the axis of the shaft l3 and the latter axis being in a centralplane through the tips of the toes It. The toes are outwardly tapered in a vertical sense whereby when the shaft. is moved through a vertical are from one extreme position to the other,.as illustrated in Fig. 1, one or the other upper surfaces of the toes It may be brought to a horizontal position. Each of the upper surfaces of the toes. i6 is provided with a pair of oppositely disposed, directional arrows [9 alongside of which are provided words indicating the character of the faces of the head toward which the arrows point. The arrows l9 and the associated words may be cast into the metal when the part M is being formed.

The head It] comprises a symmetrical, metal core consisting of a pair of identical cast metal core members 20 having centrally disposed, vertical faces in face-to-face relationship along a central plane as indicated at 2i, the core memoers as being held together by a pair of rivets 22. Opposed depressions formed in the surfaces 2! of the core members 2s,-indicated at 23 in Fig. 4, define a substantially rectangular, upwardly opening, centrally disposed slot 2a in the head. The verticalsides of the depressions 23 form the side walls 25 of the slot 2%, which side walls are parallel, vertical, and in symmetrical disposition with respect to the vertical, central plane of the metal core of the head defined by the surfaces 2 i. The dimensions of the slot are such that when one upper surface of one toe I6 is brought into substantially flush relation with the upper surface of the head, the lower surface of the opposed toe will be close to the bottom of the slot 24. While the slot is substantially rectangular, the mouth thereof may be reduced in length by means of overhanging lip portions indicated at 2B in order to prohibit the entry of grass and other debris into the slot.

In order to retain the shaft in its positions of utility with respect to the head, there is provided ball detent means as follows. Each of the toes i8 is provided with a laterally directed socket 27, the sockets being in horizontally spaced relation to the pivot l8 and opening toward the opposed side walls of the slot. A ball 28 is loosely mounted in each of the sockets 21 and is urged outwardly by means of a spring 29 compressed between the bottom of the socket and the ball. A plurality of hemispherical depressions 3c are provided in the side walls 25, the depressions being arranged to provide upper and lower symmetrically disposed pairs of depressions engageable by the balls '23 when the shaft is at its limits of movement. It will be appreciated from the foregoing that the metal mass of the head is symmetrically disposed with respect to the shaft E3 in either relative position of the shaft to the head.

In order that the same club may be used for a plurality of purposes, it is preferred that the impact faces be of differing character, as indicated at St and However, it will be appreciated that the face members are substaninterlock with angularly disposed edge portions of the impact members so as to key the impact members to the core, such portions being indicated generally at 83 and 34 in Fig. 5. The outer surface of each of the core members 2c is provided with a plurality of cylindrical sockets 35, as more clearly seen in Fig. 7, and the inner surface of each of the impact faces is provided with a plurality of cooperative key projections comprising cylindrical stems 36 of smaller diameter than the sockets 35, at the inner 'ends of which are a plurality of radially projecting arms 3i. When assembling the impact face members to the core, the sockets are partially filled with a suitable adhesive in plastic condition and the key projections of the impact faces are pressed thereinto, causing the plastic to flow around and over the radial arms 37 whereby the members are locked together by the adhesive when it hardens. As will be seen in Fig. 5, the inner surfaces of the impact face members are provided with suitable depressions '38 to receive the ends of the rivets 22. It will be seen in Fig. 6 that the pivot member l3 may be loosely disposed in the transverse bore I? and in aligned openings 39 in the core members 26. Assembly of the construction is thereby facilitated, and repair is made possible since the impact face members may be removed whereupon the pivot It may be driven from its position.

Having illustrated and described a preferred embodiment of the present invention, it should be apparent to those skilled in the art that the same permits of modification in arrangement and detail. I claim as my invention all such modifications as come within the true spirit and scope of the appended claims.
