W. J. HADDEN GOLF CLUB HEAD Filed March 26, 1931 Patented July 4, 1933 FECE EBATEIN-"I"I WILLIAIVI JAMES HA'DEN OF GLASGOW, SCOTLAND, ASSIGNOR T0 DONALDSON IVANUFACTURING COMPANY LIMITEE, OF GLASGOW, SCOTLAND GOLF CLUB HEAD Application led March 26, 1931, Serial No. 525,530, and in Great kBritain November 20, 1930.

This invention relates to heads for golf clubs oi the driver,7 brassie or spoon type, usually termed wooden clubs, having either metallic or wooden shafts.

` An object of the present invention is to provide a metal golf club head of the aforesaid type which will be relatively simple and cheap to manufacture. A further object is to provide such a golf club head which will facilitate giving of top spin to the ball. A further object is to provide a head which will have a good appearance, which will not be liable to split or crack, and which will withstand rough treatment without being unduly marked. A further object is to concentrate the weight of the head more directly behind the ball so as to give a hammerlike etl'ect when striking the same. A still further object is to provide a head which will make it easier to lift out a golf ball from a had or cupped lie. Further objects will appear throughout the following specilication.

The head is strong and not liable to split 5 or crack, has a good appearance, and is able to withstand rough treatment without being unduly marked. It is simple to manufacture.

I will now describe my invention simply by way or' example with reference to the accompanying drawing whereon Fig.V l is an elevation of a golf club head constructed in accordance with this invention, the view being taken from the toe7 end thereof.

Fig. 2 is an inverted plan view of the head shown` in Fig. 1, illustrating the T-:tormation.

Fig. 3 is a section on the line III-III, Fig. 1.

Fig. 4 is a sectional plan on the line IV-IV, Fig. l.

Referring to the drawing The head shown is formed as a single n stamping of the material marketed under the 4"- trade-mark Duralumin, or of Duralumin alloy, there being no sole except for the bottom of the weighting and strengthening rib or part t and the bottom part 5 of the front face 6, these two parts 4 and 6 concentrating the weight of the head in T-formation (in horizontal. section) behind the ball and providing a somewhat T-shaped sole and the remainder of the head being hollowed out at 9 and l0 in the stamping process and leaving vacant spaces on both sides of the rib. In the stamping operation the rib is thickened towards the front face 6 so as to curve outwardly and merge into the rear surface of the `front face, while the top face 8 or" the head extends rearwardly from the front face over the rib thereby giving the head the usual rounded appearance from the top.

rlhe socket 7 may be internally screw threaded and tapered for the reception of an externally screw threaded and tapering shaft, the two when secured together, forming a combined screw and push joint as described in U. S. A. specication Serial No. 301,672, liled August 23, 1928.

In a modification, the rib may be removable and replaceable, so that ribs of diierent sizes and/or weights may be iitted in accordance with the desire of the user. In this case the ribs may be secured in position by screws, pins or otherwise.

Instead of being made as a stamping, the head may be cast, while a. bone or other face plate could be fitted in the front face of the head. In the case of a casting, a sole may be formed complete and integral with the rest of the head.

A head constructed in accordance with this invention gives a benelicial effect in striking a ball, as it acts in similar manner to that of a usual hammer head, a large proportion of the weight of the head extending in the direction in which the ball is struck. This arrangement gives rigidity combined with lightness to the head and also disposes a large proportion ofthe weight of the head behind the ball.

A head in accordance with this invention can be comparatively cheaply and easily made as one stamping and a number of heads can be made to an accurate size from the same dies. Heads for brassies, drivers, and spoons for example, can be made from the same dies or similar sets of dies with different lofts, thereby ensuring that sets of clubs can be marketed with truly similar heads. There is no shrinkage or warping as obtains A head Yforacgolf `ollil) comprising a'body formed as a unitary structure and having an upper Wall extending its full length and width and a depending Wall only along the front edge of the upper Wall, the said front Wall having its intermediate portion of increased thickness and merging into a rib extending from the front Wall to the rea-r edge of the upper wall, 'said rib -haying lower edge flush with the lower 'edge faceo the front .wall and the rear portion of its lower edge extendingiipwardly `tointerseot the rear edge vof thenpper Wall.

In testimony whereof I ai'xmy signature.

WILLIAM JAMES HADDEN.
