Application March 24, 1932. Serial No. 600,963 6 Claims. (01. 273-77 Themain objects of this invention are:
First, to provide an improved weighted golf club head in which the weight is effectively secured and at the same time the weight is not 5 seriously weakened by the securing means.
Second, to provide an improved golf club head in which weights of composition may be effectively secured in position.
Third, to provide means for securing weights 10 to wood head golf clubs in which the mass is not materially reduced.
Fourth, to provide a golf club head in which the securing means for the weight is entirely concealed.
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.
a A structure which is a preferred embodiment of my invention is illustrated in the accompanying drawing, in which:
Fig. 1 is a front elevation of a wood golf club head embodying the features of my invention, the hosel being partially broken away.
Fig. 2 is an inverted view, the hosel being omitted.
Fig. 3 is a transverse section on line 33 of Fi 1.
Fig. 4 is a fragmentary horizontal section on line 4-4 of Fig. 1.
Fig. 5 is a fragmentary horizontal section of a modified form or embodiment of my invention.
In the embodiment illustrated in the accompanying drawing, the head 1 is formed of wood and is provided with the usual hosel 2. The head is formed with a recess 3 in its rear edge adapted to receive the weight 4 and a recess 5 in its striking face 6 adapted to receive the striking plate 7. The head also has a recess 8 adapted to receive the sole plate 9.
The head has a transverse stepped or shouldered bore 10 adapted to receive the screw 11, the head 12 of which engages the shoulder 13 of the bore. This bore opens to the recess 5 in the striking face and after the screw is inserted and threaded into the back weight 4 to clamp it into the recess, the plug is inserted, this being preferably a dowel pin glued into the hole behind the screw.
The striking plate '7 is secured in its recess 5 over the bore by means of the fillister head screw 14, so that this screw 14 not only secures the face plate but it covers the bore for the screw securing the weight. This enables the attaching of the weight without materially reducing its relatively brittle material such as ivory or composition which are quite expensive, and when secured by the common method do not bear up well under constant use.
In the embodiment of Fig. 5. a plurality of bores 10 and screws 11 are provided.
A satisfactory method of assembling the parts is to form by suitable milling or other cutter the weight recess, this recess being conformed to the shape of the back weight and striking plate to be used. The back weight is then fitted by hand and glued in position in the recess. The head is then placed in a drill press jig with the center of its face in a horizontal position to the drill. A hole is then drilled through the head to a point approximately half way through the inserted weight, and is then counter-bored to the desired depth. The screw is then inserted, preferably the part of the hole adapted to receive the threads being tapped in order not to subject the head to undue splitting strains which otherwise might result from the insertion of the screw. The counter-bored hole is then plugged with a dowel, the face plate recess milled and the striking plate inserted, as described, which conceals the weight securing means.
I have illustrated and described my improvements in highly satisfactory embodiments thereof. I have not attempted to illustrate or describe certain other modifications and adaptations as it is believed that this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
