Application filed December 18, 1925. Serial No. 76,143.

My invention relates to golf clubs, the same being designed for the production of a metal head for such clubs as the driver and the brassie.

The advantages of ainetal head over one made of wood are well known, but difliculty has been experienced in the past in the production of a metal head, as a substitute for one made of wood, because of the inability to produce a metal head of substantially thesame weight as a wooden one, because of the inability to produce a metal head which, with the shaft of the'club, will have the same or a similar balance as a wooden one, and because of the inability to obtain a metal head which will have the resiliency of one made of wood.

in the diiferent views.

I have overcome these clifiiculties by making a metal head with an enlarged cavity in it and an insert of hard resilient material completely enclosed thereby.

The details of the invention will hereinafter appear and that which I regard 'asnew will be set forth in claims.

I prefer to use aluminum as the material of which the head 1 of my improved club is made.

7 This is cast to the shape of the particular club'to be produced, such as a driver or a brassie, and is formed with a cavity 2 in the body thereof which has been shown as extending throughout the length and breadth of the body, leaving relatively thin walls at all points. Extending upwardly at an angle from the body 0f the head is a shank 3 which is bored longitu-. dinally for the reception of the usual shaft 4 which may be either of wood or metal. A rectangular, preferably oblong-shaped, opening 5 in the lower face of the head communicates with the cavity 2. Around this opening the'metalof the head is cut away to form a flat or substantially flat surface 6, the two side edges of which are undercut, as shown at 7, to form shoulders between which fits the wear plate 8. Within the cavity are cast enlargements or thickened portions forming shoulders or abutments 9 and 10. These shoulders are in vertical alignment with'each other and with one end wall of the opening 5. It is between these shoulders and the inner wall of the striking face ll'of the club that the insert l2'is located. This insert is preferablymade of hard wood of the proper resiliency and of a weight or density to impart to the finished head the proper total weight. It may, however, be made of any other hard material of suitable'resiliency and weight. It is cut to the proper shape to fit snugly against the upper wall 13 of the cavity'2, against the shoulders 9 and 10 at one end and against the inner wall of the striking face-11 at the opposite end. The grain ofthe wood runs longitudinally of the oblong opening 5,-- 7

that is, in the direction of the length of the head between the shoulders 9 and 10 and the striking face 11. It is made of such size that it is necessary to force it into place so that it will tightly and snugly engage both the'shoulders 9 and 10 and the inner wall of thestriking face 11. The lower face of the insert 12' lies flush with the flattened surface 6 surrounding the opening 5 and is provided with a longitudinally extending groove 14. This groove, when the insert is in place, forms a continuation of a centrally disposed inclined groove 15 in the flattened surface 6 at the end of the opening 5 0pposite the striking face 11. The insert 12 is held in place within the cavity 2 by the wear 7 plate 8. It is additionally held in place by a plurality of dowel pins 16' which are introduced into the insert through openings '17 in the upper face of the head of the club, the outer ends of said dowel pins being trimmed down so that they lie flush with the outer surface of said upper face.

The wear plate 8 is preferably made of bronze although it may be made of any other suitable metal. fit upon the flattened surface 6 surrounding the opening 5, and between the undercut parts, the upper face of the wear'plate 8 It is of a size and shape to .which the screw 25passes.

is recessed as shown at 19 and 20 to produce the laterally extending rib 21. There is also formed on the upper side of the wear plate 8, at the center thereof, an upwardly extending lug 22 forming .a shoulder 23. The width of the lug 22 corresponds with the width of the grooves 14 and 15 so that the wear plate 8 may be introdueed intoposition by sliding it longitudinally between the undercut shoulders; 7 on the lower face of the head 1. When finally seated the shoulder 23 bears against the inner Wall of the striking face 11, the end of the wear plate 8 lies flush with the striking face 11 and the opposite end thereof is beveled off to conform or merge intothe lower surface of the head. The plate 8 is retained in place by the screws 24 and 25. Two screws 24 havev been shown extending through the plate 8 into the body 1 and a .third screw 25 has been shown extending through the plate 8, into the'insert 12. The rib 21 on the underside of the plate 8 is tangent to the Opening in the plate through As a result of this construction a broad bearing surface is provided behindthe screw 25 so that there is no tendency to shear ofi' the head of the screw. This is also effectually prevented by the engagement of the shoulder 28 with the inner wall of the striking face 11. The engagement of said shoulder with said wall prevents any longitudinal or sliding movement of the wear plate 8 as the face 11' of the club strikes against the ball. The rib 21 and shoulder 23, in connection with the undercut shoulders 7 and the screws 242 and 25, serve to effectually lock the wear plate 8 in position and prevent any movement What ever on the head of the club.

While I have described my invention as particularly adapted for use in connection withthe manufacture of drivers and brassies, it will be understood that it maybe found desirable to construct other clubs such as putters, in accordance therewith.
