GOLF CLUB Filed Dec. 29, 1932 7 B A 2%6/76 A/rz/r 11v VEN TOR UNITED S T Patented July 9, 1935 PATENT OFFICE I... Young Company; Detroit, Mich. v Application December '29, leaaserial No. 649,296 2 Claims. (01.273-77) The main objects of this invention are:

First, to provide an improved golf club in which the weight is so disposed as to be most effective in propelling aball.

Second, to provide an improved iron head golf club in which the head is relatively more compact as compared with clubs of standard types and at the same time is properly balanced and very [effective at the moment of impact with the ball.

Third, to provide a golf club head having a blade provided with coacting longitudinally extending vertically spaced weight areas adapted to impart to the ball a low trajectory, great speed, and long flight.

Objects relating to details and economies of my invention will appear from the description to follow. The invention is defined and pointed out in the claims. I

A structure which is a preferred embodiment of my invention is illustrated in the accompanying drawing, in which:

Fig. 1 is a rear elevation of .a No. 1 iron golf club head embodying the features of my invention, the shaft being omitted.

Fig. 2 is a transverse section on Fig. 1.

Fig. 3 is a transverse section on line 3-3 of Fig. 1.

Fig. 4 is a front end elevation of a No. 1 iron club head.

Fig. 5 is a front end elevation of a No. 4 iron club head.

Fig. 6 is a front end elevation of a club head.

In iron head golf clubs, it has been customary heretofore to place the majority of the weight in the sole or to make the head wider at the sole and taper it toward its top or upper edge, the theory being that this heavy sole or low positioning of the weight facilitates the followline 2-2 of No. 6 iron through of the swing, and, while it accomplishes this purpose and adds momentum to the swing, I have discovered that it doesnot produce the maximum distance to the ball that it is possible to impart with the weight of the club positioned as I have done.

One of my objects is to provide a more compact blade than has heretofore been produced and my improved structure has resulted in very substantial improvements without in anywise destroying the balance or feel of the club.

My improved golf club head has the usual inclined face 1, its rear side being conformed to provide a central longitudinal recess 2. From the bottom of this recess the head is transversely and outwardly curved as indicated at 3 and 4 so that equal weight distribution at both the top porthere isa relatively thin central zone. This zone is slightly below the longitudinal center of the head and thicker towards each edge, the weight being so constructed on the back or rear side of the club head or blade as to give approximately 5 tion and lower portion opposite the longitudinal curved recess as shown by the portion or mass of 7 weight at 3 being more condensed than the wider back formation .at 4.

The result is that the condensed lower weight 10 structure acts as a medium to elevate the ball at impact while the upper and wider reinforced weight structure propels the ball for greater distance through the action of upper weight structure counteracting the elevation of the ball, pro- 5 duced by the lower reinforced back weight structure. The effect as demonstrated blends the two important distance producing factors into one, namely, trajectory and maximum carry aided in distance obtained by the overspin applied to the 20 ball by the reinforced top weight which naturally gives the ball more run after contacting the ground.

The hosel l is suitably positioned relative to the head to receive the shaft. These improvements are desirable throughout the full range of a set of clubs. Figs. 4 to 6, inclusive, illustrate my improvements as applied to three of a set of irons, the blades 1 l, M and I6 being arranged at different angles of inclination to change the loft of the ball. The heads illustrated are the No. 1, No.

4 and No. 6 irons. I have not attempted to illustrate or describe the adaptation to the various intermediate clubs, as it is believed that this disclosure-will enable those skilled in the art to embody .or adapt the same as may be desired.

My improved arrangement of the weight on the back of the blade imparts an action to the ball at the moment of impact that has been impossible with clubs of the prior art. The weight at the bottom of the blade definitely helps the club head to follow through and has a tendency to elevate the ball. The increased weight at the upper portion of the blade has a tendency to counteract the action of the lower part of the blade and. lower the flight of the ball. Therefore, the two definite weight areas at the. top and bottom of the blade coact with each other to keep the ball at a minimum trajectory which gives the greatest speed and the longest flight possible. The great weight .at the top compensates the weight at the bottom of the blade and keeps the ball from skying. The extra weight at the bottom of the blade helps to get the club head through and adds greater ease of control.

substantially from end to end thereof, the bottomof the recess being slightly below the transverse center of the blade, the rear of the club being outwardly curved from said recess, the curvature above the bottom of the recess extending from end to end of the club head and conformed so that the longitudinal center of weight is approximately at the normal point of contact of the club with the golf ball.

2. An iron golf club head having an inclined face, the rear side of said head having a transversely concaved longitudinal recess extending longitudinally from end to end thereof, the bottom of the recess being below the transverse center of the blade, the rear side of the club being outwardly curved from the bottom of said recess to provide a center of weight thereabove and a center of weight therebelow, the longitudinal center of weight of the head being approximately at the normal point of contact of the head with the ball.
